Systematic review and meta-analysis of therapeutic alliance, engagement, and outcome in psychological therapies for psychosis.

AIM: The moderate association between therapeutic alliance (TA) and psychological therapy outcome is well established. Historically, the field has not focused on people with a severe mental illness. This is the first review to conduct a meta-analysis of associations between TA and therapeutic engagement as well as outcome in psychological therapy for psychosis. ELIGIBILITY CRITERIA: Eligible studies conducted a quantitative investigation of the relationship between TA during a psychological therapy and outcome at a subsequent time-point. METHOD: A systematic review examined the relationship between TA and engagement as well as outcome measures within psychological therapy for psychosis. Correlational meta-analyses using an aggregate random effects model were conducted. RESULTS: Twenty-four studies were eligible for inclusion (n = 1,656) of which 13 were included in the meta-analyses. Client- and therapist-rated TA were associated with engagement in therapy (rclient (c)  = 0.36, p = .003; rtherapist (t)  = 0.40, p = .0053). TA was also associated with reduction in global (rc  = 0.29, p = .0005; rt  = 0.24, p = .0015) and psychotic symptoms (rc  = 0.17, p = .0115; rt  = 0.30, p = .0003). The systematic review identified no evidence or limited evidence for a relationship between TA during therapy and depression, substance use, physical health behaviours, global as well as social functioning, overall mental health recovery, and self-esteem at follow-up. Although number of studies was small, TA was related to a reduced risk of subsequent hospitalization in 40% of analyses (across two studies) and improved cognitive outcome in 50% of analyses (across three studies). CONCLUSIONS: The observed TA-therapy engagement and TA-outcome associations were broadly consistent with those identified across non-psychotic diagnostic groups. Well-powered studies are needed to investigate the relationship between TA and process as well as outcome in psychological therapy for psychosis specifically. PRACTITIONER POINTS: This is the first review to conduct a meta-analytic synthesis of the association between therapeutic alliance (TA) and both engagement and change in outcome in psychological therapies for psychosis. TA (as rated by therapist and client) was associated with the extent of therapeutic engagement as well as reduction in global mental health symptoms and psychotic symptoms. The significant associations between TA and engagement as well as change in outcome identified in the current review are broadly consistent with those observed across non-psychotic diagnostic groups. We consider factors that could impact upon the dynamic and potentially interdependent relationships between TA and therapeutic techniques, including attachment security and severity of paranoid ideation.

Virtual reality in the treatment of persecutory delusions: randomised controlled experimental study testing how to reduce delusional conviction.

BACKGROUND: Persecutory delusions may be unfounded threat beliefs maintained by safety-seeking behaviours that prevent disconfirmatory evidence being successfully processed. Use of virtual reality could facilitate new learning. AIMS: To test the hypothesis that enabling patients to test the threat predictions of persecutory delusions in virtual reality social environments with the dropping of safety-seeking behaviours (virtual reality cognitive therapy) would lead to greater delusion reduction than exposure alone (virtual reality exposure). METHOD: Conviction in delusions and distress in a real-world situation were assessed in 30 patients with persecutory delusions. Patients were then randomised to virtual reality cognitive therapy or virtual reality exposure, both with 30 min in graded virtual reality social environments. Delusion conviction and real-world distress were then reassessed. RESULTS: In comparison with exposure, virtual reality cognitive therapy led to large reductions in delusional conviction (reduction 22.0%, P = 0.024, Cohen's d = 1.3) and real-world distress (reduction 19.6%, P = 0.020, Cohen's d = 0.8). CONCLUSION: Cognitive therapy using virtual reality could prove highly effective in treating delusions.

Targeting Recovery in Persistent Persecutory Delusions: A Proof of Principle Study of a New Translational Psychological Treatment (the Feeling Safe Programme).

BACKGROUND: Many patients do not respond adequately to current pharmacological or psychological treatments for psychosis. Persistent persecutory delusions are common in clinical services, and cause considerable patient distress and impairment. Our aim has been to build a new translational personalized treatment, with the potential for wide use, that leads to high rates of recovery in persistent persecutory delusions. We have been developing, and evaluating individually, brief modular interventions, each targeting a key causal factor identified from our cognitive model. These modules are now combined in "The Feeling Safe Programme". AIMS: To test the feasibility of a new translational modular treatment for persistent persecutory delusions and provide initial efficacy data. METHOD: 12 patients with persistent persecutory delusions in the context of non-affective psychosis were offered the 6-month Feeling Safe Programme. After assessment, patients chose from a personalized menu of treatment options. Four weekly baseline assessments were carried out, followed by monthly assessments. Recovery in the delusion was defined as conviction falling below 50% (greater doubt than certainty). RESULTS: 11 patients completed the intervention. One patient withdrew before the first monthly assessment due to physical health problems. An average of 20 sessions (SD = 4.4) were received. Posttreatment, 7 out of 11 (64%) patients had recovery in their persistent delusions. Satisfaction ratings were high. CONCLUSIONS: The Feeling Safe Programme is feasible to use and was associated with large clinical benefits. To our knowledge this is the first treatment report focused on delusion recovery. The treatment will be tested in a randomized controlled trial.

The In-Session and Long-Term Role of a Significant Other in Motivational Enhancement Therapy for Alcohol Use Disorders.

OBJECTIVE: To examine how significant other (SO) language in support of or against client abstinence from alcohol influences clients' in-session speech and drinking behavior over the 9 months post-Motivational Enhancement Therapy (MET). METHOD: Sequential analyses were used to examine the language of Project MATCH clients who invited an SO to participate in an MET session. Hierarchical regressions investigated the predictive relationship between SO language and clients' post-treatment drinking behavior. A cohort analytic design compared the change language of these SO-involved participants against a matched group who chose client-only therapy. RESULTS: 'SO Support Change' language increased the odds of client Change Talk in the next utterance (p<.01). SO Support Change did not significantly predict reduced post-treatment drinking, whereas 'SO Against Change' significantly predicted an increase in average drinks per drinking day (DDD) across months 7-9 post-MET (p=.04). In the matched comparison, the proportion of change-related client language was comparable across the SO-involved and client-only groups. CONCLUSIONS: Motivational interviewing theory was supported by the sequential association between SO and client language as well as the predictive link between SO Against Change and client drinking intensity. Given the centrality of pro-sobriety language in the literature, it was surprising that SO Support Change did not predict alcohol use outcomes. Findings are discussed in relation to contemporary treatment process research and clinical practice.
