What it is

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…

Format

• 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…
• 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).

Who practises it, and how they are trained or regulated

• Continue weekly scheduling, graded tasks and routine regulation throughout.
• BATD-R sequence
• 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…

Questions to explore with your client

• What drew you to it, and what are you hoping it will change?
• Does it involve any substance, plant preparation, remedy or supplement? Has your doctor or prescriber been told, especially about any medication you take?
• Does it involve fasting, a special diet or 'detox'? Have you discussed this with your doctor?
• Is it a group, retreat or community? How do they respond if someone wants to leave or raises a concern?
• How do you and the practitioner understand what is happening, in spiritual or cultural terms? Is that a source of comfort, worry, or both?
• Who runs it, and what training or registration do they hold?
• What actually happens in a session or meeting, and how often?
• What does it cost, and is there pressure to commit to more?
• How do you feel afterwards, in the hours and days that follow?
• Does it fit with, or clash with, the work we do here?

What practitioners of it watch for

• turning it into a rule the client "fails". Working: client reports using it between sessions.
• sleep problems needing specific insomnia treatment. Working: more consistent days on the monitoring sheet.
• activities too vague to schedule. Working: a list of specific activities spread across several life areas.
• goals phrased as feelings ("be happy"); convert to behaviour. Working: goals are specific enough to schedule.
• the therapist accepting vague accounts ("I just didn't"). Working: barriers become predictable and get planned for.

When to involve someone else

• New or worsening physical symptoms, or advice to stop or change prescribed medication: involve the client's doctor or prescriber.
• Signs of coercion, isolation from family and friends, escalating costs or secrecy: discuss openly and consider safeguarding.
• A crisis or thoughts of suicide: follow your crisis protocol. In the US, call or text 988; in the UK and Ireland, Samaritans on 116 123.
