Behavioural activation

1. Introduction

Version followed: Martell, Dimidjian & Herman-Dunn, Behavioral Activation for Depression: A Clinician's Guide (Guilford, 1st ed. 2010; 2nd ed. 2021/22), as operationalised in the COBRA trial protocol (Richards et al., 2016) and Martell's 2018 ACBS workshop slides. Where the brief, values-based variant (BATD-R; Lejuez, Hopko, Acierno, Daughters & Pagoto, 2011) differs, it is named explicitly. The 2nd edition's contents are not drawn on here; its additions (transdiagnostic chapter, fidelity and progress measures, client booklet) are noted from the publisher page only [uncertain].

Behavioural activation (BA) is a structured, brief, idiographic behavioural treatment for depression. It descends from Ferster's (1973) functional analysis of depression and Lewinsohn's reinforcement model, and became a stand-alone treatment after Jacobson et al.'s (1996) component analysis of CBT found the activation component alone performed as well as the full package. Its core idea of change: depression is maintained when life changes reduce access to positive reinforcement (or increase punishment) and the person responds with understandable short-term escape and avoidance (withdrawal, inactivity, rumination) that further shrinks contact with reward. Therapy works "outside-in": the client changes what they do according to a plan rather than mood, re-contacting natural reinforcers and solving life problems, and mood follows. Cognitions are not disputed; thinking such as rumination is treated as behaviour with a function. [source: Martell 2018 ACBS slides; Wikipedia; Ezquer Tiberio 2014 review of Martell et al.; Lejuez et al. 2011 abstract]

Two lineages exist: (a) Martell/Jacobson/Dimidjian BA (Seattle), formulation-driven, 16–24 sessions; (b) Lejuez/Hopko BATD/BATD-R, a simpler protocol built on values, daily monitoring, a ranked activity hierarchy and behavioural contracts, 10–12 sessions (sometimes fewer). Both are used by non-specialists (COBRA used junior mental-health workers; BATD-R lists bachelor's-level staff). There is no single certifying body. [source: COBRA slides; CEBC BATD page]

2. Framework

Format and dose (Martell BA, COBRA protocol). Up to 20 individual sessions of about 50–60 minutes over 16 weeks, optionally twice weekly for the first two months, then weekly, then spaced; plus up to 4 optional booster sessions. Group delivery is possible but the protocol is written for individual work. [source: Martell 2018 ACBS slides on COBRA; DPI patient brochure for session length]

Format and dose (BATD-R). 10–12 weekly sessions of 30–50 minutes, individual or group (groups of roughly 10–20 for mild depression, 3–5 for more impaired clients); about five minutes a day of client monitoring and planning; effects reported with shorter courses (e.g. 6 sessions in some case series). [source: CEBC BATD page; BATD-R breast-cancer case series abstract (Psicooncología, UCM)]

Standard session structure (all phases). (1) Brief check-in and progress measure (commonly PHQ-9); (2) collaboratively set agenda; (3) review last week's activity assignment in detail; (4) focal topic for the session (new skill or module); (5) plan and troubleshoot the next assignment with specifics; (6) summary and feedback from the client. [source: Ezquer Tiberio 2014 review (agenda, assignments, progress review); ENLIVEN stance in Martell 2018 slides; DPI brochure (PHQ-9)]

Phase I – Core BA (roughly sessions 1–8) [source: Martell 2018 slides]

Goals: assess the presenting problem and context (including risk); present the BA model; link mood to behaviour; begin activity monitoring; build a functional analysis and an individualised BA case formulation with the client; set short- and long-term goals; start activity scheduling; introduce TRAP/TRAC to spot avoidance and plan alternatives.
Move on when: the client can describe their own formulation (what triggers withdrawal, what it gives them short term, what it costs), is completing at least some monitoring/scheduling, and specific targets are clear [synthesis: the slides list contents but no explicit transition criteria; session numbers are approximate].

Phase II – Modules (roughly sessions 9–16) [source: Martell 2018 slides]

Mandatory modules: rumination; problem-solving.
Optional modules chosen from the formulation: functional equivalence; incorporating values; anxiety; punishment (aversive contexts); communication; alcohol and substance use.
Continue weekly scheduling, graded tasks and routine regulation throughout.
Move on when: symptoms have improved meaningfully on the progress measure and the client is setting and troubleshooting assignments with little prompting [synthesis].

Phase III – Maintenance and relapse prevention (last 2–4 sessions) [source: Martell 2018 slides]

Goals: shift to self-directed activity planning with less therapist support; identify personal relapse triggers and early warning behaviours; review progress on goals and valued activities; use TRAP/TRAC to pre-plan responses to future triggers; write a written relapse-prevention plan.
Boosters: optional, flexible; review earlier modules and the relapse plan.

BATD-R sequence [uncertain: the full manual is not drawn on; this order is from CEBC, IHS training slides and the UCM case series, with session placement from general knowledge of the manual]

Rationale and alliance; start daily monitoring of activities (with mood/enjoyment and importance ratings; a low-literacy monitoring form exists).
Review monitoring; identify values across life areas and list activities that would express them.
Select activities and rank them by difficulty; begin scheduling from the easier end.
Onward: weekly planning with explicit frequency/duration goals, ongoing monitoring, behavioural contracts with supportive people, troubleshooting barriers, progressing up the list; final session consolidates gains and plans relapse prevention.

3. Guiding principles

The ten principles of BA (Martell, Dimidjian & Herman-Dunn 2010; paraphrased) [source: Ezquer Tiberio 2014 review; DeCou 2017 UW slides; Martell 2018 slides]

Changing what people do changes how they feel. Practically: every session ends with a concrete behavioural plan, not just insight.
Life changes can trigger depression; short-term coping keeps people stuck. Practically: look for the losses or stressors that cut reinforcement and the avoidance that followed; validate both as understandable.
What precedes and follows important behaviours shows what will be antidepressant for this client. Practically: do functional analysis on the client's own records rather than prescribing generic pleasant activities.
Structure and schedule activities according to a plan, not a mood. Practically: specify day, time, place; the client does it whether or not they feel like it.
Change is easier when starting small. Practically: if an assignment was not done, make the next step smaller rather than pushing harder.
Emphasise naturally reinforcing activities. Practically: choose activities likely to be rewarded by the client's real environment (connection, accomplishment, valued outcomes), not arbitrary self-rewards or what merely looks good on paper.
Act as a coach. Practically: the client is the expert on their life; the therapist brings method, structure and encouragement.
Take an empirical, problem-solving approach; every result is useful. Practically: frame assignments as experiments; an incomplete task yields data about barriers.
Don't just talk, do. (Slides render it "Don't just talk, Do!") Practically: rehearse, role-play, start tasks in session, and keep discussion tied to action.
Troubleshoot possible and actual barriers. Practically: before any assignment, ask what could get in the way and plan for it; after, review what did.

Therapist stance: ENLIVEN (Martell 2018 slides) [source: Martell 2018 ACBS slides]

Establish an agenda: set it collaboratively and check in when the session drifts.
Nurture activation: keep monitoring and scheduling central; favour value-driven over mood-driven behaviour.
Learn together: coach, not expert; all information is useful.
Be non-judgemental: behaviour is just behaviour; the client's values need not match yours; values are not morals.
Validate: the emotion, the function the behaviour serves, the attempts at change, and how hard change is.
Encourage: stay hopeful; encourage experimentation, risk-taking and experiencing emotions the client labels negative.
Naturally express warmth: be present and genuine; avoid stock empathy phrases.

Therapist strategies: ACTIVATE (as reported from Martell et al. 2010) [source: Ezquer Tiberio 2014 review; exact wording in the book not verified, uncertain]

Assess what maintains the depression · Counter avoidance with structured activation and problem-solving · give Time to specific elements · Include monitoring · Validate · Assign activities · Troubleshoot · Encourage.

Further stance principles from the BA literature

Function over form: the same activity (e.g. watching TV) may be rest for one client and avoidance for another; judge by its consequences. [source: Martell 2018 slides (functional analysis, functional equivalence module); IHS slides (video-gaming example)]
Outside-in, not inside-out: acting first and letting mood follow, rather than waiting for motivation. [source: DeCou 2017 UW slides]
Avoid "just do it": exhortation without analysis, small steps and troubleshooting is not BA. [source: DeCou 2017 UW slides]
Values guide activity choice (strongly in BATD-R; an optional module in COBRA BA). [source: CEBC; Martell 2018 slides]
Thinking is treated by its function, not its content: no cognitive restructuring; rumination is targeted as avoidance behaviour. [source: Martell 2018 slides; Wikipedia]

4. Intervention inventory

Order follows the Martell/COBRA protocol (Phase I → modules → relapse prevention), then the BATD-R-specific procedures. All example language is illustrative and the author's own unless quoted and cited. Session placements are typical, not fixed.

4.1 Assessment and risk screening (session 1–2)

Purpose / when: First sessions; establish the problem, its onset context, current functioning, and safety. [source: Martell 2018 slides ("assess the presenting problem"); risk procedure is standard practice, synthesis]
Steps:
1. Ask when the depression started and what changed in the client's life around then (losses, moves, role changes, health, relationships, work).
2. Map a typical day now versus before: what has dropped out, what has increased (bed time, screens, alcohol, rumination).
3. Administer a baseline measure (e.g. PHQ-9) and repeat each session. [source: DPI brochure]
4. Screen for suicidal thoughts and self-harm using your service's standard structured risk assessment; if present, build a written safety plan and include lethal-means counselling (safe storage or removal of means, involving supporters) before activation work. [synthesis: standard practice; not specified in the BA sources]
5. Screen for conditions needing other priority care (mania/hypomania, psychosis, substance dependence requiring withdrawal management, medical causes of fatigue). [synthesis]
Example language (illustrative): "Let's look at what your weeks looked like before things got hard, and what they look like now. The differences usually tell us where to start."
Watch for: the client describing life changes in purely internal terms ("I just lost motivation"); gently ask what happened in their environment. Working: you can name 2–3 concrete losses of reinforcement and the coping behaviours that followed.

4.2 Presenting the BA model (rationale) (session 1–2)

Purpose / when: Early, and re-presented whenever motivation dips. BATD-R places extra emphasis on the rationale and alliance. [source: Martell 2018 slides ("explain the BA model", "link mood to behaviour"); Lejuez et al. 2011 abstract]
Steps:
1. Draw the cycle using the client's own material: life event/context → less reward or more stress → low mood, fatigue → withdrawal/avoidance (brings short-term relief) → even fewer rewards and more problems → lower mood. [source: Lewinsohn model and ABC model, Martell 2018 slides]
2. Explain that the treatment targets the avoidance loop by changing actions on a plan, starting small, rather than waiting to feel better first (outside-in).
3. Normalise: the avoidance made sense; it is not laziness or a character flaw.
4. Describe what therapy involves: weekly monitoring, scheduling, experiments, reviews.
5. Ask for the client's reaction and examples that fit or don't fit; adjust.
6. Optionally give a written handout or client booklet (the 2nd edition supplies one). [source: Guilford page]
Example language (illustrative): "When we feel low it's natural to pull back. That gives a bit of relief today, but over weeks it means fewer of the things that used to give you a lift. We're going to work on that loop from the outside, by changing what you do in small planned steps, and see what happens to your mood."
Watch for: client hearing "just get busy" or feeling blamed. Working: the client can retell the cycle with one of their own examples.

4.3 Goal setting

Purpose / when: Phase I, after the model; gives direction for activation. [source: DPI brochure (goals tied to values); Martell 2018 slides (review goals in Phase III)]
Steps: (1) Ask what the client would be doing if depression were less in the way; (2) translate into observable short-term goals (next few weeks) and longer-term goals (months); (3) for each long-term goal, identify a first small step; (4) record and revisit at progress reviews.
Example language (illustrative): "If we filmed a good week three months from now, what would we see you doing?"
Watch for: goals phrased as feelings ("be happy"); convert to behaviour. Working: goals are specific enough to schedule.

4.4 Activity monitoring

Purpose / when: From session 1 or 2 onward; the core data source for functional analysis and for linking activity to mood. [source: Wikipedia (hourly activity and mood chart); Ezquer Tiberio 2014 (activity, emotion, intensity; optionally mastery and pleasure); IHS slides (importance, enjoyment, mastery ratings)]
Steps:
1. Give an hour-by-hour weekly grid. For each block the client notes what they did and the emotion/mood with an intensity rating (e.g. 0–10); optionally ratings for mastery and pleasure (Martell) or enjoyment and importance (BATD-R).
2. Agree how often to record (ideally every 2–3 hours, at minimum each evening; set phone reminders). Partial records still count.
3. Practise filling in the last few hours in session.
4. Next session, review together: look for patterns (when mood is lowest/highest, what activities precede changes, time spent in bed or alone, avoidance), and mark activities to increase and decrease.
5. Repeat monitoring periodically to check change, or targeted to specific times of day.
Example language (illustrative): "Think of this as collecting data, not homework you can fail. Even three or four entries a day will show us something."
Watch for: retrospective all-at-once filling (less accurate; encourage nearer-real-time); global ratings ("all 2s") that hide variability, so ask about the best and worst hour; literacy limits (BATD-R has a simplified form; use pictures, voice notes or a phone). Working: client and therapist can identify at least one activity–mood link the client had not noticed.

4.5 Functional analysis and BA case formulation

Purpose / when: Phase I; repeated whenever a new problem behaviour appears. This is what distinguishes BA from simply increasing pleasant events. [source: Martell 2018 slides]
Steps:
1. Choose a specific episode from the monitoring (e.g. Sunday afternoon in bed).
2. Walk through the ABC: what happened before (situation, trigger), how the client felt, what they did, and what followed immediately and later.
3. Identify the function: what did the behaviour achieve short term (escape from a feeling, avoiding a demand, relief) and what did it cost long term?
4. Link episodes into the individual formulation: life context and vulnerabilities, the reduction in reward/increase in punishment, secondary problems, and the recurring avoidance patterns. [source: Lewinsohn integrative model, Martell 2018 slides]
5. Write or draw the formulation with the client and check it fits; revise as new data come in.
6. Derive targets: behaviours to increase (likely to be naturally reinforced or solve problems) and avoidance to replace.
Example language (illustrative): "When you got into bed after that call, what did it do for you in the moment? And how did the evening go after that?"
Watch for: confusing form with function; a behaviour is only a target if its function is avoidance or it costs the client. Working: the client starts spotting functions spontaneously.

4.6 TRAP / TRAC

Purpose / when: Phase I onward; teaches the client to recognise avoidance loops and choose alternative coping. [source: Martell 2018 slides; Wikipedia; DeCou 2017 slides]
Steps:
1. Introduce TRAP: Trigger (situation), Response (emotional/physical reaction), Avoidance Pattern (the habitual escape behaviour).
2. Fill one in from the client's week (e.g. seeing an ex's photos → sadness, anger → staying in, brooding, checking their social media — the example in Martell's slides).
3. Ask about short-term relief versus long-term cost.
4. Build TRAC: same Trigger and Response, then Alternative Coping (an approach behaviour, e.g. calling a friend for a walk, or, late at night, singing along to music).
5. Plan when the trigger is likely to recur and rehearse the alternative; schedule it where possible.
6. Review: did the trigger occur, what was done, what happened.
Example language (illustrative): "So the trigger was the message, the response was that sinking feeling, and the pattern was going quiet and scrolling. What's one thing you could try next time instead, even for ten minutes?"
Watch for: alternatives that are actually subtler avoidance; alternatives too large to try while distressed. Working: the client can name their TRAPs in session and reports at least partial TRACs.

4.7 Activity scheduling

Purpose / when: From session 2–3 throughout; the central change procedure ("plan, not mood"). [source: Martell 2018 slides; Ezquer Tiberio 2014]
Steps:
1. Choose activities from the formulation: avoided tasks, previously rewarding activities, valued activities, routine anchors. Prefer those likely to be naturally reinforced.
2. Make each specific: the 5 Ws — what, when, where, with whom, and why it matters to the client. [source: Martell 2018 slides]
3. Write it on the schedule with day and time (the client writes it in their own calendar/phone during session).
4. Ask the client to rate mood (and mastery/pleasure) during or after the activity.
5. Ask what could get in the way; plan around each barrier (see 4.17).
6. Ask about expectations, but treat the aim as planning and commitment, not testing beliefs. [source: Martell 2018 slides]
7. Review next session: what was done, partially done, not done; what happened to mood; what was learned.
Example language (illustrative): "Let's pin it down: which day, what time, where will you be, and will anyone be with you? Put it in your phone now while we're here."
Watch for: overloaded schedules (a common pitfall per DeCou 2017); only pleasant activities when important avoided tasks are driving distress; mood ratings showing no change for weeks (re-check function, intensity, and whether the activity is reinforced in the client's environment). Working: completion rises, and mood ratings vary with activity.

4.8 Graded task assignment (breaking tasks down)

Purpose / when: Whenever a scheduled activity is too big, was not done, or the client is overwhelmed. [source: Martell 2018 slides ("break goals into small, doable steps"); principle 5; Ezquer Tiberio 2014 (structuring and grading tasks)]
Steps: (1) Name the larger task; (2) list component steps in order; (3) make the first step small enough that the client is confident they can do it (ask for a 0–10 confidence rating; if below about 7, shrink it — [synthesis: threshold is a common heuristic, not from the sources]); (4) schedule only the first one or two steps; (5) build up on success.
Example language (illustrative): "Clearing the backlog is the goal, but this week the step might just be opening the post and sorting it into two piles."
Watch for: steps defined by time spent rather than completion where completion matters, and vice versa; perfectionism. Working: steps are being completed and the client proposes the next step.

4.9 Routine regulation

Purpose / when: When sleep, meals, waking times or daily rhythms are disrupted; depression often erodes routine and irregularity worsens mood. [source: Martell 2018 slides (routine regulation listed as a key strategy); rationale wording is synthesis]
Steps: (1) From monitoring, identify disrupted routines (rise time, bedtime, meals, hygiene, work/study blocks); (2) choose one anchor (often a fixed rise time); (3) schedule it daily, with a small reinforcing activity attached; (4) add further anchors gradually.
Example language (illustrative): "Let's pick one fixed point in the day to hang everything else on. Would getting up at the same time every day be a realistic place to start?"
Watch for: sleep problems needing specific insomnia treatment [synthesis]. Working: more consistent days on the monitoring sheet.

4.10 ACTION (client-facing problem-solving sequence for avoidance)

Purpose / when: Phase I–II; gives the client a portable sequence for turning a TRAP into a TRAC on their own. Originates in Addis & Martell's (2004) self-help book Overcoming Depression One Step at a Time. [source: Wikipedia]
Steps: Assess the behaviour and its effect on mood (is it avoidance?); Choose an alternative response; Try it; Integrate alternatives that work into routine; Observe and evaluate results; Never give up (keep experimenting). [uncertain: the N]
Example language (illustrative): "Before you go back to bed, run it through ACTION: what's this going to do for my mood, what else could I choose, and can I try it for fifteen minutes and see?"
Watch for: turning it into a rule the client "fails". Working: client reports using it between sessions.

4.11 Rumination module (mandatory in COBRA)

Purpose / when: Phase II, or earlier if rumination dominates the monitoring. Rumination is treated as behaviour with an avoidant function, not as thought content to dispute. Brooding is the target; reflective problem-focused thinking is not. [source: Martell 2018 slides (Treynor et al. brooding/reflection distinction; two broad approaches)]
Steps:
1. Functional analysis of rumination: identify when it happens (cues, times, places), what it is about, how long, and what follows (mood, tasks missed). Ask whether it has ever produced a solution or relief. [source: Wikipedia (evaluate whether ruminating has helped); Martell 2018 slides]
2. Distinguish brooding from problem-solving: apply the two-minute rule — if thinking about a problem has not yielded a step towards a solution within about two minutes, treat it as brooding. [source: Martell 2018 slides]
3. Rumination Cues Action (RCA): agree that noticing rumination is itself the cue to act: either move to structured problem-solving (4.12) if there is a solvable problem, or shift attention to the present activity / do a planned alternative. [source: Wikipedia (RCA named); procedural detail: synthesis]
4. Attention to experience: practise in session directing attention to sensory detail of the current activity (sights, sounds, physical sensations, the task), returning attention whenever it drifts to brooding; assign during scheduled activities, especially those during which rumination was recorded. [source: Martell 2018 slides; Ezquer Tiberio 2014 (attention-to-experience assignments); exact exercise wording is synthesis]
5. Add rumination ratings to monitoring to track change.
Example language (illustrative): "When you've been going over it for a couple of minutes and you're no closer to a next step, that's the signal. Then the question is: is there something I can do about this right now? If yes, we problem-solve. If not, we bring your attention back to what you're doing."
Watch for: clients believing rumination is necessary to understand themselves or prevent mistakes; validate the intent, then test the outcome. Attention to experience is not meant to suppress feelings. Working: shorter, less frequent episodes and more completed activities during former rumination times.

4.12 Problem-solving (mandatory in COBRA)

Purpose / when: When life problems maintain depression or when brooding substitutes for action. [source: Martell 2018 slides]
Steps: (1) Two-minute rule check; (2) define the problem in behavioural, specific terms; (3) brainstorm as many solutions as possible without judging; (4) evaluate options (pros, cons, feasibility); (5) choose one, break it into steps and schedule it; (6) review outcome and try another option if needed. [source: Martell 2018 slides]
Example language (illustrative): "Let's write down every possible option, including silly ones, before we decide anything."
Watch for: solutions that depend entirely on others changing; very large first steps. Working: a scheduled step was carried out and the client evaluates it without catastrophising.

4.13 Incorporating values (optional module in COBRA; core in BATD-R)

Purpose / when: When activities feel empty or arbitrary, or to pick activities with lasting natural reinforcement. [source: Martell 2018 slides; CEBC; IHS slides]
Steps: (1) Explore what matters to the client across life areas (relationships, work/study, leisure, health, spirituality, daily responsibilities); (2) phrase values as directions (e.g. being a caring parent) rather than achievable outcomes; (3) for each, list concrete activities expressing it; (4) compare current monitoring with values to find gaps; (5) schedule value-linked activities.
Example language (illustrative): "You said being a dependable friend matters to you. What's one thing a dependable friend might do this week, even in a small way?"
Watch for: imposing therapist values; "should" lists driven by guilt (ENLIVEN: values are not morals). Working: activities chosen feel meaningful even when not pleasant.

4.14 Functional equivalence (optional module)

Purpose / when: When a problem behaviour serves a real need (rest, soothing, connection, escape from overwhelm) and simply stopping it leaves a gap. [source: module named in Martell 2018 slides; procedure: synthesis from BA functional-analytic principles]
Steps: (1) From functional analysis, name what the behaviour provides; (2) brainstorm alternative behaviours that meet the same need with less long-term cost; (3) schedule and test them in the trigger situation; (4) compare outcomes.
Example language (illustrative): "Scrolling at night seems to give you a break from feeling alone. What else might give you a sense of connection at that time?"
Watch for: alternatives that are not actually available at the trigger time. Working: the alternative is used and the costly behaviour drops.

4.15 Anxiety module (optional): graded approach of avoided situations

Purpose / when: When anxiety-driven avoidance blocks activation (e.g. avoiding social contact, phone calls, leaving home). [source: module named in Martell 2018 slides; IHS slides (BA adapted for anxiety-related avoidance, combine with relaxation, monitor anxiety); detailed steps: synthesis]
Consent and safety: explain that approaching feared situations temporarily raises anxiety; obtain explicit agreement for each step; the client controls pace. Contraindications/cautions [synthesis]: unmanaged suicidal crisis, active psychosis, current dangerous situations (e.g. domestic violence — approach is not appropriate where the threat is real), unstable medical conditions affected by arousal, active substance intoxication. Where a primary anxiety disorder or PTSD is driving avoidance, consider a dedicated exposure-based protocol or referral.
Steps: (1) List avoided situations linked to goals; (2) rate anticipated anxiety and order them; (3) schedule the easiest step as an activity, with anxiety ratings before, during, after; (4) encourage staying long enough to learn what happens; (5) review and step up.
Example language (illustrative): "We'll only do steps you agree to. The aim is to find out what actually happens when you go, rather than what the anxiety predicts."
Watch for: safety behaviours that keep avoidance going; overwhelm (step down, don't stop). Working: anxiety ratings fall across repetitions and the avoided activity becomes schedulable.

4.16 Punishment module (optional): reducing aversive contingencies

Purpose / when: When the client's environment actively punishes activity (critical partner, bullying workplace, hostile living situation). [source: module named in Martell 2018 slides; Ferster/Lewinsohn model (increased punishment); procedure: synthesis]
Steps: (1) Identify where activity leads to aversive outcomes; (2) problem-solve changes to the context (assertive communication, boundary-setting, seeking support, changing setting); (3) where the environment cannot be changed, schedule reinforcing activities in other contexts; (4) assess safety if abuse is disclosed and follow safeguarding procedures.
Watch for: framing the client as responsible for others' behaviour. Working: fewer punished attempts recorded; more reinforced activity elsewhere.

4.17 Communication / skills training and in-session rehearsal (optional module; rehearsal used throughout)

Purpose / when: When skills deficits (asking for help, saying no, repairing a relationship) stop activities being reinforced; and generally to make assignments more likely to happen ("don't just talk, do"). [source: communication module named in Martell 2018 slides; role-play and visualisation for setting plans into action, and teaching relationship skills, IHS slides]
Steps: (1) Pick the specific interaction; (2) model or discuss options; (3) role-play with the client, swapping roles if helpful; (4) give specific feedback; (5) rehearse again; (6) optionally rehearse in imagery the moment of starting the task; (7) schedule the real interaction.
Example language (illustrative): "Let's try it here first. I'll be your manager. What would you open with?"
Watch for: rehearsal turning into evaluation of the client. Working: the client completes the interaction and reports a response from others.

4.18 Alcohol and substance use module (optional)

Purpose / when: When substance use functions as avoidance or replaces reinforcers. [source: module named in Martell 2018 slides; BA in substance users, DeCou 2017 UW slides and Cassar et al. 2016; procedure: synthesis]
Steps: (1) Include use in monitoring; (2) functional analysis of use episodes (triggers, short-term relief, costs); (3) TRAP/TRAC with substance-free alternatives meeting the same function; (4) schedule substance-free reinforcing activities in high-risk times; (5) coordinate with addiction services where dependence is present.
Watch for: withdrawal risk (medical referral); shame suppressing honest monitoring. Working: use falls in former high-risk periods.

4.19 Troubleshooting barriers to activation (every session)

Purpose / when: Before setting and after reviewing each assignment (principle 10). [source: principle 10; Martell 2018 slides (ask about anticipated obstacles); IHS slides (assess function of a barrier, check confidence, adjust plan)]
Steps:
1. Before: ask what might get in the way (time, energy, other people, mood on the day, forgetting) and plan specific counters (reminders, smaller version, backup time, support person).
2. Ask for a confidence rating; if low, adjust the plan.
3. After: review in detail, without judgement. For anything not done, find the exact point where it stopped (didn't remember, remembered but didn't start, started but stopped) and what was happening then.
4. Assess the function of not doing it (what did avoiding it achieve?), then revise: smaller step, different time, alternative coping, problem-solve the external barrier.
Example language (illustrative): "Walk me through Tuesday at six. Where were you when you remembered the plan, and what happened next?"
Watch for: the therapist accepting vague accounts ("I just didn't"). Working: barriers become predictable and get planned for.

4.20 Progress monitoring

Purpose / when: Each session; informs pacing and phase decisions. [source: DPI brochure (PHQ-9); Guilford page (2nd ed. adds progress and fidelity measures)]
Steps: brief measure at session start; plot scores with the client; link changes to what they did that week; review goals at intervals.
Watch for: no change by around the middle of treatment — revisit formulation, assignment size and whether targets are actually avoidance [synthesis]. Working: scores fall alongside rising activity.

4.21 Relapse prevention (Phase III)

Purpose / when: Final sessions and boosters. [source: Martell 2018 slides]
Steps: (1) Review what worked (which activities, which TRACs, which routines); (2) identify likely future triggers and the client's early warning behaviours (e.g. cancelling plans, more time in bed); (3) write TRAP/TRAC plans for each; (4) have the client set their own weekly schedule unaided; (5) agree when to restart monitoring/scheduling and when to seek help; (6) offer boosters.
Example language (illustrative): "If you notice yourself starting to cancel things again, what's your first move?"
Watch for: the client attributing improvement to luck rather than their actions; draw links to their data. Working: a written plan in the client's words.

BATD-R-specific procedures

The following are the brief Lejuez/Hopko protocol's components. The manual itself (Lejuez et al., 2011) is not drawn on; details below are from CEBC, IHS slides and summaries [uncertain on specific form names and session placement].

4.22 Life areas, values and activities inventory (BATD-R)

Purpose / when: Early (about session 2) after monitoring starts; ties activation to what the client values. [source: CEBC; IHS slides; Lejuez et al. 2011 abstract]
Steps: (1) Go through each major life area (relationships, education/career, recreation, physical/mental health and spirituality, daily responsibilities [uncertain: exact list]); (2) for each, help the client state a value; (3) list several concrete, observable activities that would express that value; (4) compare with monitoring to see how well current living matches.
Example language (illustrative): "In your family life, what kind of person do you want to be? What would that look like on an ordinary Wednesday?"
Watch for: activities too vague to schedule. Working: a list of specific activities spread across several life areas.

4.23 Activity selection and ranking (BATD-R)

Purpose / when: After the values inventory; builds a hierarchy to work through. [source: CEBC (structured selection); Wikipedia (difficulty-ranked hierarchy); number of activities: uncertain]
Steps: (1) Pick a set of activities from the inventory; (2) have the client rank them from easiest to hardest; (3) start scheduling from the easier end; (4) move up as activities are completed.
Watch for: ranking by what the client thinks they should manage rather than realistic difficulty. Working: steady progress up the list.

4.24 Weekly activity planning with goals (BATD-R)

Purpose / when: Every session from about session 3. [source: CEBC (planning with ongoing monitoring); UCM case series (duration and frequency of activities)]
Steps: (1) Choose activities for the coming week from the ranked list; (2) set an ideal frequency and duration for each; (3) schedule on the daily monitoring/planning form; (4) at review, compare done versus planned and adjust.
Watch for: setting the ideal as the target too early; start with what is achievable [synthesis]. Working: planned and completed activities converge.

4.25 Behavioural contracts (BATD-R)

Purpose / when: Once the client is activating; recruits social support for chosen activities. [source: CEBC; IHS slides; Cassar et al. 2016 (contracts are one of seven tip themes)]
Steps: (1) Identify an activity that would benefit from someone's support; (2) choose a supportive person; (3) agree with the client what to ask (e.g. company, a reminder, acknowledgment when done); (4) rehearse the request; (5) the client makes the agreement and reports back.
Example language (illustrative): "Who in your life would be glad to help with this, even in a small way? What exactly would you ask them to do?"
Watch for: contracts with people who are critical or unreliable; requests the client feels ashamed to make. Working: the support happens and the activity is completed more often.

Not included as a core technique: a token-economy hierarchy variant is described on Wikipedia but was not found in either main manual's summaries [uncertain]. Cognitive restructuring is not part of BA.

5. Handling problems

Source notes: BATD-R explicitly ends with a section on barriers and strategies, and Cassar et al. (2016) group trainer tips into seven themes (rationale; alliance and self-disclosure; monitoring; values; angles and steps; contracts; combining approaches), but their specific advice is not drawn on here. Most responses below apply BA's principles; each is tagged. [source: Lejuez et al. 2011 abstract; Cassar et al. 2016 abstract]

Stuck client (no change after several weeks)

Re-do functional analysis: are scheduled activities actually reinforced in this client's environment, or chosen because they look good on paper? Shift toward naturally reinforcing and value-linked activities (principle 6). [source: principles; DeCou 2017 slides]
Check that important avoided tasks, not only pleasant events, are being targeted. [source: IHS slides (active coping)]
Check for an aversive context (punishment module), rumination during activities (attention to experience), or substance use. [source: Martell 2018 slides]
Review the case with supervision; consider whether medication review or a different treatment is indicated. [synthesis]

"Resistance" / low motivation

Treat as data, not defiance: explore the function of not acting (principle 8). [source: principles]
Return to the rationale using the client's own monitoring; validate how hard change is (ENLIVEN). [source: Martell 2018 slides]
Do not exhort ("just do it"); shrink the step and start it in session. [source: DeCou 2017 slides; principle 9]
If the client disagrees with the model, run a small experiment rather than debate. [synthesis]

Overwhelm

Reduce the number of assignments; schedule fewer, smaller steps; protect rest. [source: DeCou 2017 slides (doing too much too fast as a pitfall)]
Use problem-solving to triage life demands; schedule one first step for the most pressing. [source: Martell 2018 slides]
If overwhelm reflects crisis (bereavement, housing loss, violence), prioritise practical support and safety. [synthesis]

Non-adherence to monitoring or scheduling

Find the exact breakdown point (4.19); simplify the form (BATD-R has a low-literacy version), use phone reminders, record only key times of day. [source: Lejuez et al. 2011 abstract; procedure synthesis]
Always review what was brought, however partial; praise the attempt specifically; never ignore homework. [synthesis consistent with principle 8]
Complete or start the task in session.

Alliance ruptures

Name and invite discussion of the strain; validate; accept your share (e.g. pushing too hard, too many assignments). [synthesis: general rupture-repair practice; BA sources stress validation and genuine warmth]
Re-collaborate on the agenda and assignment size; remind that you are a coach, not an authority (principle 7).
Careful, purposeful self-disclosure is discussed by Cassar et al. (2016) as an alliance tool [source: abstract only; specifics not seen].

Modality-specific difficulties

Activation becomes more avoidance (e.g. busy work or solitary gaming that avoids family contact): check function, not just activity counts. [source: IHS slides; Martell 2018 slides]
Mood does not lift during activities: check for rumination during the activity (attention to experience); remind that mood often follows with a lag; keep rating. [source: Martell 2018 slides; lag point: synthesis]
Client feels BA is superficial or wants to talk about the past: validate; link history to current patterns via the formulation (life changes and short-term coping, principle 2); keep sessions tied to action. [synthesis]
Severe depression with very low energy: begin with routine anchors and tiny graded steps; consider twice-weekly sessions early (as in COBRA). [source: Martell 2018 slides (twice-weekly schedule); rest synthesis]
Physical illness or pain: adapt activities to capacity; BATD-R has been used with cancer patients. [source: UCM case series; adaptation: synthesis]
Lay or junior workers delivering BA: use a structured protocol and regular supervision, as in COBRA and BATD-R. [source: Martell 2018 slides; CEBC]

Suicidal ideation emerging during treatment [synthesis: standard practice]

Pause the agenda; conduct a structured risk assessment per service protocol; update the safety plan; lethal-means counselling (restricting access, safe storage, involving supporters); increase contact and escalate per local pathway. Resume activation when safe, using activities that build connection and reasons for living.

Problems the sources do not address (all synthesis)

Cultural fit: ask how activities, family roles and values are understood in the client's context; avoid assuming individualistic goals.
Group delivery: keep individual monitoring and planning; use group time for shared rationale, problem-solving and peer contracts; follow up non-attenders individually.
Remote delivery: share forms digitally; schedule assignments into the client's phone during the session.
Bipolar presentations: monitor for activation pushing towards hypomania; emphasise routine regulation and refer for specialist care.
