Friendship and social connection

1. Introduction

Version followed: the public-health framing of the US Surgeon General's Advisory Our Epidemic of Loneliness and Isolation (2023) and the WHO Commission on Social Connection report From loneliness to social connection (launched 30 June 2025), with the four-type classification of loneliness interventions from the Masi, Chen, Hawkley and Cacioppo meta-analysis; therapist-side procedures not described in those sources are marked [synthesis].

Friendship and social connection is not a psychotherapy. It is a health determinant that public-health bodies now ask clinicians to assess and address. The Surgeon General's Advisory describes social connection as having three components: structure (how many relationships, how varied, how often there is contact), function (how far others can be relied on for different needs) and quality (how positive, helpful or satisfying relationships are) [source: Surgeon General's Advisory 2023, pp. 10-11]. Social isolation is the objective state of having few relationships, roles or interactions; loneliness is the subjective, distressing gap between the connection a person wants and the connection they have [source: Surgeon General's Advisory 2023, pp. 7-8; WHO Commission report 2025, p. 8]. The UK strategy uses the Perlman and Peplau definition of loneliness as an unwelcome feeling of lack or loss of companionship [source: DCMS, A connected society, 2018, p. 18].

How change happens, as the sources frame it: loneliness is maintained partly by maladaptive social cognition (lonely people tend to expect rejection and read others negatively, then behave in ways that confirm the expectation), so the interventions with the largest effects target those thoughts, alongside building skills, support and opportunities for contact [source: University of Chicago Medicine report of Masi et al.]. Isolation and loneliness have independent effects, so reducing one cannot be assumed to reduce the other [source: WHO Commission report 2025, p. 15].

Evidence status in one line each: a meta-analysis of 148 studies (308,849 participants) found that people with stronger social relationships had about 50% greater odds of survival (OR 1.50) [source: Holt-Lunstad, Smith and Layton 2010]; the Advisory reports loneliness and isolation raising the risk of premature death by 26% and 29% [source: Surgeon General's Advisory 2023, p. 8]; WHO estimates about one in six people are lonely and links loneliness to more than 870,000 deaths a year [source: WHO Director-General's remarks, 30 June 2025]; across randomised trials, loneliness interventions had a small but significant overall effect, with social-cognition interventions (including CBT) clearly the most effective [source: University of Chicago Medicine report of Masi et al.]; WHO describes psychological approaches as showing "the most promise" while evidence on community interventions remains limited [source: WHO Commission report 2025, p. xviii].

Cross-references: behavioural activation (II 040); social prescribing (pointer 081 to V 155; green social prescribing XV 015); mutual aid and peer support (pointer 082 to V 099-135); related civic entries XV 077 and XV 079; exercise (XV 122; IX 061), sleep (XV 123; II 069, II 068), nutrition (XV 124; IX 103).

2. Framework

No source gives a manualised protocol, session count or format for clinical work on social connection; the stages below organise what the public-health sources ask of clinicians plus standard CBT structure, and the sequencing and transition criteria are [synthesis].

Ask and assess. Goal: identify disconnection and separate loneliness from isolation across structure, function and quality. The Advisory's health-sector pillar asks systems to train providers and enable them to screen for social disconnection [source: Surgeon General's Advisory 2023, pillar 3]; Holt-Lunstad and colleagues suggest medical evaluations "could routinely include variables of social well-being" [source: Holt-Lunstad et al. 2010]. Move on when you and the client can say which component is the problem and what the client wants [synthesis].
Formulate. Goal: a shared map of what keeps the disconnection going: circumstances (move, bereavement, illness, caring role, disability, transport, money, discrimination), skills, beliefs about self and others, avoidance, comorbid depression or social anxiety. Move on when the client recognises the maintaining cycle in their own examples [synthesis].
Intervene across the four types. Goal: match the work to the formulation using Masi et al.'s four categories: improving social skills, enhancing social support, increasing opportunities for social contact, and addressing maladaptive social cognition [source: University of Chicago Medicine report of Masi et al.]. Individual-level options WHO lists for older people are social skills training, peer-support and social activity groups, befriending and CBT, face to face or digital [source: WHO advocacy brief news release, 29 July 2021]. Group and individual formats did not differ in effectiveness in the meta-analysis [source: University of Chicago Medicine report of Masi et al.].
Link to community. Goal: connect the client to groups and services outside therapy (social prescribing link workers, community organisations, volunteering) [source: Surgeon General's Advisory 2023, pillar 3; DCMS 2018, p. 26]. Move on when contact with at least one non-therapy source of connection is happening without the therapist's prompting [synthesis].
Consolidate and end. Goal: a written maintenance plan, early-warning signs of withdrawal, and an ending that does not leave the therapy relationship as the client's main connection [synthesis].

Stages overlap; cognitive work usually runs alongside behavioural steps rather than before them [synthesis].

3. Guiding principles

Connection is a health issue, not a personal failing. Ask about it as routinely as sleep or alcohol; the sources tie it to mortality, heart disease, stroke, depression, anxiety and dementia [source: Surgeon General's Advisory 2023; WHO Director-General's remarks 2025].
Loneliness and isolation are different targets. A person with many contacts can be lonely; an isolated person may not feel lonely; assess both and treat what is present [source: WHO Commission report 2025, p. 15].
Assess all three components. Structure, function and quality each need a question; more contact does not fix poor-quality or harmful relationships [source: Surgeon General's Advisory 2023, pp. 10-11].
Target social cognition first among equals. The meta-analysis found thought-focused interventions most effective, so expect to work on expectations of rejection, not only on activity [source: University of Chicago Medicine report of Masi et al.].
Reduce stigma. WHO notes stigma stops lonely people seeking help, and the UK strategy aims for loneliness to be talked about without stigma; name it plainly and normalise it [source: WHO Commission report 2025, p. 12; DCMS 2018, p. 7].
Fit the population and culture. What works differs by population, age and cultural norms; adapt to the client's life stage and community [source: WHO Commission report 2025, pp. xviii, 15-18].
Therapy links outward. The therapist's job is to help the client build connection outside the room, including by referral to community organisations [source: Surgeon General's Advisory 2023, pillar 3].
Digital tools serve human relationships. Treat online contact as a bridge, not a replacement [source: WHO Director-General's remarks 2025].
The therapist is not the friend. Warmth in the relationship is not a substitute friendship; avoid multiple relationships that risk impaired objectivity or exploitation [source: APA Ethics Code, Standard 3.05].
Address practical barriers. Transport, money, disability access, hearing, language and caring duties are part of the formulation, not side issues [source: WHO advocacy brief news release 2021 (transport, built environment, digital inclusion); application to individual therapy [synthesis]].
No lifestyle prescriptions. Where connection runs through exercise, food or sleep, do not set exercise, diet or sleep schedules; route to the physician or qualified professional (see XV 122-124) [synthesis].
Safety stays in view. Loneliness often travels with depression and suicidal thinking; keep standard risk assessment active [synthesis].

4. Intervention inventory

The public-health sources name intervention types rather than step-by-step clinical procedures; the steps below are standard clinical practice organised under those types, and are [synthesis] except where a source is tagged.

4.1 Routine enquiry about social connection

Purpose / when: at intake and review with every client, because disconnection is common, stigmatised and rarely volunteered [source: Surgeon General's Advisory 2023, pillar 3 (screen for social disconnection); Holt-Lunstad et al. 2010; WHO Commission report 2025, p. 12].
Steps: (1) Ask a normalising lead-in. (2) Ask one question each on contact (structure), on whom the client could rely for practical help, advice and comfort (function), and on how the relationships feel (quality). (3) Ask directly how often the client feels lonely. (4) Note recent changes (moves, losses, retirement, illness, new parenthood, leaving education). (5) Record and revisit at review [synthesis].
Example language (illustrative): "Lots of people feel more alone than they let on, so I ask everyone. Who do you see or talk to in a usual week? If something went wrong at 2 a.m., who could you call? And how often, these days, do you feel lonely?"
Watch for: shame or minimising ("I'm fine on my own") that contradicts a thin network; a client who has contacts but none they trust; signs of depression or suicidal thinking, which need standard risk assessment. Working: the client can name the gap in their own words [synthesis].

4.2 Separating loneliness from isolation across structure, function and quality

Purpose / when: after a positive enquiry, to choose the target; the components have independent effects [source: WHO Commission report 2025, p. 15; Surgeon General's Advisory 2023, pp. 10-11].
Steps: (1) Draw three columns: who is there (structure), what they provide (function), how it feels (quality). (2) Fill each with the client. (3) Rate which column the client most wants to change. (4) Agree the first target: more contact, more reliable support, or better or safer relationships [synthesis].
Example language (illustrative): "It sounds like you see plenty of people at work, but none of them would notice if you went quiet. So the gap might be less about numbers and more about having someone close. Does that fit?"
Watch for: harmful or controlling relationships showing up in the quality column, which change the plan (see 5.7); a client wanting more contact when the real gap is closeness. Working: a target the client endorses [synthesis].

4.3 Standardised measurement

Purpose / when: baseline and progress tracking, or when the client finds a questionnaire easier than talking.
Steps: (1) Choose a measure: the UCLA Loneliness Scale (Version 3) is a 20-item self-report scale with four-point frequency ratings (Russell 1996) [source: EdInstruments entry]; in UK settings the Office for National Statistics recommended package combines one direct question on how often a person feels lonely with a three-item scale adapted from the UCLA scale [source: DCMS 2018, p. 22]. (2) Check permissions and the version used in your service; do not copy items into your own forms. (3) Give it at baseline and at review. (4) Discuss the result rather than only scoring it [synthesis].
Example language (illustrative): "This short questionnaire asks how often you feel certain ways about other people. There are no right answers. We'll look at it together, then do it again in a while to see what's shifted."
Watch for: WHO notes there is no validated instrument covering all three components of social connection and no consensus on which tool to use clinically, so a loneliness score does not measure isolation or relationship quality [source: WHO Commission report 2025, pp. 26-29]. Working: scores and the client's account move together [synthesis].

4.4 Social network mapping

Purpose / when: to make structure and function visible, find dormant ties and plan contact [synthesis].
Steps: (1) Put the client in the centre of a page. (2) Place people in rings by closeness: household and closest, friends and family, wider acquaintances, groups and services. (3) Mark contact frequency, direction of support and quality (supportive, neutral, draining, harmful). (4) Circle dormant ties that could be renewed. (5) Mark empty areas (no one for fun, no one for practical help). (6) Pick one tie to act on [synthesis].
Example language (illustrative): "Let's draw who's around you, including people you've lost touch with. Sometimes the map shows a door that's still open, like an old friend who'd be glad to hear from you."
Watch for: grief when the map shows how much has been lost (bereavement, migration, estrangement); allow time for it. Working: the client spots at least one realistic next contact [synthesis].

4.5 Formulating the loneliness cycle

Purpose / when: when the client avoids contact, expects rejection or reads neutral cues as hostile; the meta-analysis framed loneliness as involving inaccurate beliefs about self and how others see one [source: University of Chicago Medicine report of Masi et al.].
Steps: (1) Take a recent example (a message not answered, a party declined). (2) Trace the sequence: situation, thought, feeling, body, behaviour, what others then did. (3) Draw how the behaviour confirmed the belief (withdrawing led to fewer invitations). (4) Name the cycle in the client's words. (5) Agree what could be tested [synthesis on structure; cognitive target per Masi et al.].
Example language (illustrative): "So the thought was 'they only invited me to be polite', you felt heavy and stayed home, and since then they haven't asked again. Can you see how the thought ended up looking true even if it wasn't?"
Watch for: the client hearing "it's your fault"; stress that the cycle is common and understandable. Working: the client starts noticing the cycle between sessions [synthesis].

4.6 Cognitive restructuring of social threat beliefs

Purpose / when: the core of the social-cognition type that the meta-analysis found most effective, with CBT singled out [source: University of Chicago Medicine report of Masi et al.].
Steps: (1) Identify the hot belief ("people find me boring", "I'm a burden"). (2) Rate belief strength. (3) Gather evidence for and against, including times people sought the client out. (4) Generate alternative explanations for ambiguous events (busy, shy themselves, missed the message). (5) Write a balanced statement. (6) Re-rate and link to a behavioural test (4.7) [synthesis on steps].
Example language (illustrative): "When your friend took a day to reply, your mind went straight to 'she's had enough of me'. What else could explain a day's delay? If a friend told you this story, what would you say to them?"
Watch for: beliefs that are accurate (the client is being excluded, or is in a hostile setting): then the task is problem-solving or changing settings, not reframing [synthesis]. Working: lower belief ratings and less avoidance [synthesis].

4.7 Behavioural experiments on social predictions

Purpose / when: to test expectations of rejection in real contact; pairs with 4.6 [synthesis].
Steps: (1) State the prediction and how likely it feels. (2) Design a small, specific step (send one message, ask one colleague to lunch). (3) Plan how to tell whether the prediction came true. (4) Drop safety behaviours where possible (over-apologising, leaving early). (5) Review: what happened, what it means for the belief, what next [synthesis].
Example language (illustrative): "Your prediction is that if you message your cousin, she'll ignore it or be cold. Shall we find out? Send it this week, and we'll look at what actually happened, whatever it was."
Watch for: a genuinely bad outcome; plan in advance how to read it (one response is not proof) and how to cope. Working: predictions become less extreme over repeated tests [synthesis].

4.8 Social skills work

Purpose / when: one of Masi et al.'s four types, and listed by WHO as a promising individual-level option, for clients who lack specific skills (starting and keeping conversation, listening, self-disclosure, asking for help, handling conflict) [source: University of Chicago Medicine report of Masi et al.; WHO advocacy brief news release 2021].
Steps: (1) Pinpoint the skill from real examples. (2) Explain and model it briefly. (3) Role-play with the client, swapping roles. (4) Give specific feedback on one or two points. (5) Agree a real-world practice. (6) Review and refine [synthesis on steps].
Example language (illustrative): "You said conversations die after 'how are you'. Let's practise: I'll be the colleague, and you try one follow-up question about something I've said. Then we'll swap."
Watch for: skills deficits that suggest a neurodevelopmental difference or social anxiety disorder warranting assessment (see 5.6); the client feeling patronised. Working: smoother real conversations reported, more follow-up contact [synthesis].

4.9 Graded social activity scheduling

Purpose / when: for isolation and withdrawal, using the behavioural-activation framework (II 040); creating opportunities for contact is one of the four types [source: University of Chicago Medicine report of Masi et al.; method II 040].
Steps: (1) List possible social activities with the client, from easy to hard. (2) Link each to the client's values (belonging, usefulness, fun). (3) Choose a first step the client is confident about. (4) Schedule it concretely (day, place, how they will get there). (5) Review and step up when the client is ready. The client sets the pace; no frequency targets are set here [synthesis].
Example language (illustrative): "Of these, which feels possible this week, even on a bad day? Going to the library talk feels like a 3 out of 10 for difficulty. Shall we pencil that in and plan how you'll get there?"
Watch for: where activity is physical (walking groups, sport), do not prescribe durations or intensity; check with the client's physician or a qualified exercise professional (XV 122). Working: activities are happening and are linked to mood or meaning [synthesis].

4.10 Joining groups and peer-support or activity groups

Purpose / when: WHO lists peer-support and social activity groups among promising individual-level interventions; regular, shared-interest groups give repeated low-pressure contact [source: WHO advocacy brief news release 2021; rationale [synthesis]].
Steps: (1) Explore interests, identities and values. (2) Research options together (local listings, faith communities, clubs, mutual aid, cultural associations). (3) Anticipate the first-visit hurdle and rehearse an introduction. (4) Agree to try a group more than once before judging it. (5) Debrief each visit [synthesis].
Example language (illustrative): "First visits are the hardest for nearly everyone. What if you go twice before deciding? Let's work out what you'll say when someone asks what brought you."
Watch for: groups with high-control or exploitative features (see 5.7); mutual-aid groups are covered under pointer 082 (V 099-135). Working: the client is recognised by name at the group [synthesis].

4.11 Referral to social prescribing and link workers

Purpose / when: when the client needs practical help finding community activities or services; the UK strategy committed to social prescribing connector schemes with link workers guiding people to community groups, and the Advisory asks health systems to link patients to community organisations [source: DCMS 2018, p. 26; Surgeon General's Advisory 2023, pillar 3]. Full guide: pointer 081 (V 155); green social prescribing XV 015.
Steps: (1) Check local routes (GP practice, primary care network, voluntary-sector hub). (2) Explain what a link worker does and does not do. (3) With consent, share a short summary of the client's goals and barriers. (4) Prepare the client for the first meeting. (5) Debrief and keep the therapy goals aligned [synthesis on steps].
Example language (illustrative): "There are people whose job is to know what's on locally and help you get to it. Would you like me to help you get a referral? I can pass on what you've told me matters most, if you're happy for me to."
Watch for: the strategy states social prescribing does not replace medical care [source: DCMS 2018, p. 34]; keep treating any mental-health condition. Working: the client attends a linked activity [synthesis].

4.12 Befriending services

Purpose / when: for housebound, very isolated or older clients for whom groups are not yet possible; WHO lists befriending services among promising individual-level options [source: WHO advocacy brief news release 2021].
Steps: (1) Identify local or national befriending schemes (telephone or in person) [synthesis]. (2) Discuss what the client wants from it. (3) Support the referral. (4) Use the relationship as a step towards wider contact where the client wishes [synthesis].
Example language (illustrative): "Some organisations match people with a volunteer who calls or visits regularly, just to chat. Would that feel welcome, or a bit odd?"
Watch for: the client feeling it signals failure (address the stigma, 4.16); scheme safeguarding checks for vulnerable adults. Working: the client looks forward to contact [synthesis].

4.13 Volunteering and serving others

Purpose / when: for clients who feel useless or a burden, or who connect more easily through shared tasks; the UK strategy encourages volunteering and community participation, and the Advisory lists serving the community among everyday actions [source: DCMS 2018, p. 16; Surgeon General's Advisory 2023, letter, p. 5 (everyday suggestions)]. Cross-refer XV 077 and XV 079.
Steps: (1) Explore causes the client cares about. (2) Match to the client's energy, skills and access. (3) Start with a bounded role. (4) Review the social as well as the task side [synthesis].
Example language (illustrative): "You said you miss feeling useful. Is there a cause close to your heart where helping out would also put you alongside other people?"
Watch for: over-commitment, people-pleasing and helper burnout, especially in clients with caring roles [synthesis]. Working: the client reports contact and a sense of contribution [synthesis].

4.14 Maintaining and deepening existing friendships

Purpose / when: when ties exist but are drifting or shallow; the Advisory's letter suggests everyday acts such as answering "that phone call from a friend" and making time to share a meal [source: Surgeon General's Advisory 2023, p. 5].
Steps: (1) From the map (4.4), pick one or two relationships the client values. (2) Plan a small reach-out. (3) Practise graded self-disclosure: sharing a bit more of what is going on. (4) Practise responsiveness: remembering, following up, asking. (5) Notice reciprocity over time [synthesis].
Example language (illustrative): "You mentioned your old housemate. What would a low-pressure message look like? Something like 'Saw this and thought of you, how are things?'"
Watch for: one-sided relationships in which the client always gives; disclosure that moves too fast for the friendship. Working: two-way contact, some of it initiated by the other person [synthesis].

4.15 Repairing a ruptured or estranged relationship

Purpose / when: when a valued friendship or family tie ended in conflict and the client wants to try repair [synthesis].
Steps: (1) Clarify what the client wants (reconnection, closure, an apology given or received). (2) Review the rupture from both sides. (3) Assess safety: do not encourage contact with an abusive person. (4) Draft and rehearse a short, non-blaming approach. (5) Prepare for any response, including none. (6) Debrief [synthesis].
Example language (illustrative): "If she wrote back tomorrow, what would you most want to have said? And if she doesn't reply, what will help you live with that?"
Watch for: pressure from family to reconcile with someone harmful; grief if repair fails. Working: the client acts in line with their values whatever the outcome [synthesis].

4.16 Working with stigma and shame about loneliness

Purpose / when: throughout, because stigma stops lonely people seeking help [source: WHO Commission report 2025, p. 12; DCMS 2018, p. 7].
Steps: (1) Name loneliness plainly and as common. (2) Explore what the client believes loneliness says about them. (3) Separate the feeling (a signal of unmet need) from self-judgement. (4) Use compassionate self-talk alongside 4.6 [synthesis].
Example language (illustrative): "Feeling lonely is a bit like feeling hungry: it tells you something you need is missing. It doesn't mean something is wrong with you."
Watch for: the hunger comparison is an illustration, not a claim from the sources; drop it if it does not help. Working: the client talks about loneliness with less shame and tells someone else [synthesis].

4.17 Reviewing digital connection

Purpose / when: when online life replaces or displaces in-person contact, or when digital contact is the main bridge (housebound, rural, disabled clients); WHO says digital tools should support, not replace, human relationships, and the Advisory includes reforming digital environments among its pillars [source: WHO Director-General's remarks 2025; Surgeon General's Advisory 2023, pillar 4].
Steps: (1) Map online activity: which uses bring connection, which bring comparison, conflict or isolation. (2) Keep what connects and use it as a bridge (a group chat leading to a meet-up). (3) Agree changes the client chooses. (4) For low digital skills, signpost digital inclusion help [synthesis; digital inclusion listed by WHO advocacy brief news release 2021].
Example language (illustrative): "Which bits of your phone time leave you feeling closer to people, and which leave you feeling more on the outside?"
Watch for: romance or friendship scams and online grooming aimed at lonely people; AI companions, whose effectiveness and risks WHO says need further study [source: WHO Commission report 2025, p. xviii; scam point [synthesis]]. Working: online contact leads to more, not less, real-world contact [synthesis].

4.18 Group CBT for loneliness

Purpose / when: where a service can run groups; the meta-analysis found no difference between group and individual formats, and a group gives in-session contact to practise with [source: University of Chicago Medicine report of Masi et al.; practice rationale [synthesis]].
Steps: (1) Screen members for fit and risk. (2) Agree group rules on confidentiality and respect. (3) Combine the cycle formulation (4.5), restructuring (4.6), skills practice (4.8) and between-session experiments (4.7). (4) Build in member-to-member contact. (5) Plan for connection after the group ends [synthesis].
Example language (illustrative): "Everyone here knows what it's like to feel on the outside. That means this room is a good place to try something new and see how people really respond."
Watch for: members feeling excluded inside the group (which re-enacts the problem); dominant members. Working: members contact each other between sessions, where the group agrees to that [synthesis].

4.19 Adapting to life stage, culture and transitions

Purpose / when: what works differs by population, and needs and norms vary with age and culture [source: WHO Commission report 2025, pp. xviii, 15-18]; WHO notes high rates among young people and in low-income countries [source: WHO Director-General's remarks 2025].
Steps: (1) Identify the transition (starting university, new parenthood, divorce, retirement, bereavement, migration, illness or disability). (2) Ask what connection looks like in the client's culture and family (collective versus individual norms, faith community, language). (3) Use the DSM-5-TR Cultural Formulation Interview where cultural factors shape the problem. (4) Adapt the options in 4.9-4.13 to fit [synthesis].
Example language (illustrative): "Back home, who were your people, and how did you spend time with them? What would a version of that look like here?"
Watch for: imposing a single model of friendship; for young clients, safeguarding and parental involvement as appropriate, never naming minors in records shared outside the service [synthesis]. Working: a plan the client says fits their life [synthesis].

4.20 Linking connection to physical health and other care

Purpose / when: when disconnection coexists with physical illness, hearing or mobility problems or caring duties; the Advisory links disconnection to heart disease, stroke and dementia and asks health systems to train providers and address patients' social needs [source: Surgeon General's Advisory 2023; WHO Director-General's remarks 2025].
Steps: (1) With consent, tell the client's physician that disconnection is a treatment target. (2) Flag practical barriers a physician or occupational therapist can address (hearing assessment, mobility aids, transport schemes) [synthesis]. (3) Where the client wants activity-based connection, route exercise questions to the physician or a qualified exercise professional (XV 122), sleep questions to sleep medicine and CBT-I (XV 123; II 069) and food questions to a registered dietitian (XV 124) [synthesis]. (4) Do not advise on medicines.
Example language (illustrative): "You said you stopped going out partly because you can't follow conversations in noisy rooms. Would it help if we asked your doctor about a hearing check?"
Watch for: disordered eating behind avoidance of shared meals: screen and refer to a registered dietitian or an eating-disorder service; for support, the National Alliance for Eating Disorders [synthesis]. Working: barriers are being dealt with alongside the therapy [synthesis].

4.21 Maintenance and ending plan

Purpose / when: before ending, so gains hold and the therapy relationship is not the client's main connection [synthesis].
Steps: (1) Review the map (4.4) and measures (4.3) against baseline. (2) List what helped. (3) Name early warning signs (cancelling plans, not replying, staying in). (4) Write the first responses to them. (5) Taper sessions where possible while outside contacts increase. (6) Discuss feelings about ending openly [synthesis].
Example language (illustrative): "Ending here is a loss too, and it's fine to say so. Let's write down what you'll do if you notice yourself pulling back again."
Watch for: a crisis or new withdrawal timed with ending. Working: the client can describe their plan without prompts [synthesis].

5. Handling problems

The public-health sources do not address in-therapy difficulties; all guidance in this section is [synthesis] unless tagged.

5.1 Stuck client: "there's no one and nothing out there"

Treat the statement as a belief to test (4.6) and as a possible sign of depression; assess mood and, if depression is present, treat it alongside (behavioural activation, II 040).
Shrink the step: one brief, low-risk contact (a shop conversation, a reply to a message) rather than a group.
Do the research together in session, so the "nothing out there" claim is checked against real local options.
Illustrative: "Let's not decide yet whether anything out there would suit you. Let's just look, together, for ten minutes."

5.2 Resistance and "I prefer being alone"

Respect solitude that the client genuinely values; isolation without loneliness may need no change, though its health risks can be discussed neutrally [source: WHO Commission report 2025, p. 15 (independent effects)].
Explore whether the preference protects against expected rejection or past hurt; if so, work on that (4.5-4.7).
Use motivational questions about the client's own goals, not the therapist's.
Illustrative: "Some people really are happiest with a lot of time alone. I'm curious whether that's you, or whether being alone has become safer than the alternative."

5.3 Overwhelm and social anxiety

Step down the hierarchy, slow the pace and plan exits for any social activity.
If anxiety is intense and persistent across social situations, assess for social anxiety disorder and offer, or refer for, an evidence-based treatment for it before pushing for exposure to groups.
For trauma-related fear of people, stabilise and work with the trauma before graded social steps.

5.4 Non-adherence to between-session tasks

Review what got in the way without blame: the task may have been too big, poorly timed or blocked by practical barriers (cost, transport, caring duties, disability access).
Rehearse the first moment of the task in session (the opening line, the walk to the door).
Turn a missed task into data for the cycle (4.5): what thought came up just before skipping it?

5.5 Rupture and over-reliance on the therapist

Expect that a lonely client may feel the therapist is their main relationship. Acknowledge it warmly, and keep building outside ties.
Hold boundaries on contact between sessions and on any social relationship with the client; avoid multiple relationships that risk impaired objectivity or exploitation [source: APA Ethics Code, Standard 3.05].
Treat perceived slights (a late reply, a cancelled session) as live examples of the loneliness cycle and repair them openly.
Illustrative: "When I had to move our session, it sounds like part of you heard 'she doesn't care'. I'm glad you told me. That's exactly the kind of thought we've been working on."

5.6 Skills differences, neurodivergence and communication barriers

If social difficulty is lifelong and broad, consider assessment for autism or other neurodevelopmental conditions, and adapt goals to the client's own preferences rather than neurotypical norms.
Check hearing, vision, language and speech barriers, and involve the physician or relevant professional (4.20).

5.7 Harmful relationships and exploitation

More contact is not the goal when relationships are abusive or controlling; quality matters [source: Surgeon General's Advisory 2023, pp. 10-11 (quality component)].
Screen for domestic abuse, financial exploitation, scams and high-control groups that target lonely people; follow safeguarding and adult-protection duties and local reporting procedures.
Plan for safety before any change that could provoke the controlling person.

5.8 Suicide risk

Loneliness, a sense of being a burden and thwarted belonging warrant direct questions about suicidal thoughts as part of standard risk assessment; act on risk using your service's procedures, and counsel on safe storage or removal of lethal means where relevant.
Give crisis resources: 988 Suicide and Crisis Lifeline (US); Samaritans 116 123 (UK and Ireland).

5.9 Grief, migration and losses behind the loneliness

When disconnection follows bereavement, divorce or migration, work with the loss first; network-building too early can feel like replacing the person lost. For bereavement see the death and mourning entries in this domain.

5.10 Limited local options or access

Where services are scarce (rural areas, low-income settings, disability access), combine digital bridges (4.17), telephone befriending (4.12) and existing ties (4.14); advocate with the client for transport or access support where possible. WHO lists transport, the built environment and digital inclusion as community-level levers [source: WHO advocacy brief news release 2021].

5.11 Progress on measures but not in life, or the reverse

Because no single tool captures structure, function and quality [source: WHO Commission report 2025, pp. 26-29], check all three in conversation before concluding that therapy is or is not working.
