Since the introduction of early intervention services, 40-60% of people experiencing their first episode of psychosis have made a full or partial recovery (Craig et al., 2004). However, some people continue to not respond well with routine early intervention services and still have problems in their social functioning. This can lead to long-term social difficulties, such as withdrawal, isolation, and lack of integration into the community.
Traditional Cognitive Behavioural Therapy (CBT) is recommended by the National Institute of Health and Clinical Excellence (NICE) for people with psychosis and has been demonstrated to be effective in helping with the symptoms of psychosis (NICE, 2014; Shepherd, 2014; Wykes et al, 2008). However, the traditional CBT approach does not explicitly aim to improve social functioning, which is extremely important to the recovery needs of people experiencing psychosis (Pitt et al, 2007). In particular, gaining meaningful employment, accessing education, spending time with friends and family, are important.
This study aimed to see if a social recovery CBT intervention, delivered within early intervention teams, could help improve social activity for people experiencing psychosis.
This study is a single-blind randomised controlled trial in four early intervention teams (Birmingham, Lancashire, Norfolk and Suffolk). Participants were people with psychosis who had been with early intervention services for 12 to 30 months, had current psychotic symptoms (operationally defined by the PANSS (Kay et al, 1987) score ≥4 ), and difficulties in social functioning (operationally defined by ≤ on the Time Use Survey; Gershuny, 2011).
Participants were randomised to either:
- The social recovery CBT intervention plus early intervention service,
- Or early intervention services only (usual treatment).
The intervention was social recovery CBT, which was delivered in three stages:
- Development of a detailed assessment with a particular focus on behaviours, therapeutic engagement and the development of a formulation, and identification of a problem list.
- Participant and therapist working together to prepare for meaningful activities including, e.g. referrals to vocational agencies and community sport activity groups. Cognitive work involved tackling stigma, negative self-belief, improving agency, and undertaking behavioural experiments.
- Engagement in new activities, fostering feelings of mastery and agency, problem-solving, and working systemically with the participant’s social network.
Participants completed outcomes at:
- Post therapy (9-months)
- Follow-up (15 months)
The primary outcome was structured activity at 9-months (measured by the Time Use Survey (Gershuny, 2011)), which examines the number of hours spent in meaningful activity per week.
Secondary outcomes were general pathology and negative symptoms (measured using the PANSS; Kay et al, 1987), anxiety (Social Interaction Anxiety Scale; Mattick & Clark, 1998), depression (Beck Depression Inventory; Beck, Steer & Brown, 1996), hopelessness (Beck Hopelessness Scale; Beck & Steer, 1988), hope (Adult Trait Hope Scale; Snyder et al., 1991) and meaning in life (Meaning in Life Questionnaire; Steger. Frazier, Oishi & Kaler, 2006).
Quality of data
Missing data for the primary outcome was low post-therapy (7%) and follow-up (16%) demonstrating acceptable rates. Higher rates of missing data was reported for other secondary measures such as the PANSS (20% post-therapy and 35% at follow-up), which may demonstrate a risk of bias on this outcome.
155 participants were randomly allocated to either receive CBT social recovery therapy (n=76) or early intervention services alone (n=79). Baseline characteristics were similar in both groups. The majority of the sample were male, white British, had English as a first language, and were single.
Participants received an average of 16.49 sessions, and 81% of participants received an adequate ‘dose’ of therapy. The researchers reported that therapists had excellent fidelity to the treatment model. Seven participants dropped out of therapy and seven did not receive an adequate dose.
- The primary outcome of time in structured activity was significantly higher by 8.1 hours in the group that had social recovery CBT compared to the control group post-therapy, but this improvement was not maintained at follow-up.
- Constructive economic activity (time in employment) also improved post-therapy for the social recovery CBT group (compared to the control group), but this was not maintained at follow-up
- All other outcomes showed no benefit for the social recovery CBT intervention with the exception of hope at follow-up.
Social recovery CBT demonstrated improvements in structured activity post-therapy over usual treatment, but this was not maintained at follow-up. All secondary outcomes, except for hope at follow-up, did not demonstrate any significant improvements for social recovery CBT. The authors state that it may be the high level of missing data which had impacted on the findings.
Strengths and limitations
The study followed best practice procedures, for example described by Consolidated Standards of Reporting Trials (CONSORT; Schulz et al, 2010) for conducting a trial which improved the reliability and validity of results. This included; prospectively publishing the research protocol, transparent reporting of results, following good clinical practice guidelines, recruiting from a variety of sites, participants being randomly allocated to conditions by people external to the research team, researcher assistants being blind to allocation, blind break monitoring, and use of intention to treat analysis.
The researchers were also able to recruit a vulnerable group of people with moderate to severe difficulties in their social functioning.
- The prospective protocol did not state at what time point (post-therapy or follow-up) the primary and secondary outcomes would be examined
- After publishing the protocol, but prior to the study commencing, the authors chose to look at the primary outcome of structured activity use at post-therapy (9 months) as their primary outcome
- Additional secondary outcome were added that were not on the original protocol. However, the authors of the study were transparent about this
- Another potential limitation is the missing data at follow-up, which is likely to increase the risk of bias in the study findings.
Implications for practice
This study provides some evidence for focusing on social recovery in people receiving care from early intervention services. It shows that people experiencing psychosis who also struggle with social functioning can and are willing to engage in a therapy that aims to improve their activity levels. It also demonstrates that social recovery is an important issue that participants wanted to talk about and focus on in therapy.
