Predictors of adherence to cognitive-behavioural therapy in first-episode psychosis.

OBJECTIVE: To investigate predictors of adherence with a cognitive-behavioural intervention in first-episode psychosis (FEP) patients. METHOD: Predictors of adherence to cognitive-behavioural therapy (CBT) were longitudinally investigated in the experimental arm of a randomized controlled trial designed to evaluate the effectiveness of a CBT intervention for relapse prevention early in the course of psychosis when compared with treatment as usual within 2 high quality, youth oriented, specialist FEP programs (the EPISODE II trial). RESULTS: Longer duration of untreated psychosis (DUP) and poorer level of insight predicted poor adherence to CBT. This association remained significant after controlling for potential confounders. CONCLUSIONS: Treatment delay may decrease adherence with CBT in FEP patients. Reducing DUP and promoting insight early in the course of psychosis are likely to enhance adherence with CBT.

Staged treatment and acceptability guidelines in early psychosis study (STAGES): A randomized placebo controlled trial of intensive psychosocial treatment plus or minus antipsychotic medication for first-episode psychosis with low-risk of self-harm or aggression. Study protocol and baseline characteristics of participants.

AIM: It is now necessary to investigate whether recovery in psychosis is possible without the use of antipsychotic medication. This study will determine (1) whether a first-episode psychosis (FEP) group receiving intensive psychosocial interventions alone can achieve symptomatic remission and functional recovery; (2) whether prolonging the duration of untreated psychosis (DUP) in a sub-group according to randomisation will be associated with a poorer outcome and thereby establish whether the relationship between DUP and outcome is causative; and (3) whether neurobiological changes observed in FEP are associated with the psychotic disorder or antipsychotic medication. Baseline characteristics of participants will be presented. METHODS: This study is a triple-blind randomized placebo-controlled non-inferiority trial. The primary outcome is the level of functioning measured by the Social and Occupational Functioning Assessment Scale at 6 months. This study is being conducted at the Early Psychosis Prevention and Intervention Centre, Melbourne and includes young people aged 15 to 24 years with a DSM-IV psychotic disorder, a DUP less than 6 months and not high risk for suicide or harm to others. Strict discontinuation criteria are being applied. Participants are also undergoing three 3-Tesla-MRI scans. RESULTS: Ninety participants have been recruited and baseline characteristics are presented. CONCLUSIONS: Staged treatment and acceptability guidelines in early psychosis will determine whether antipsychotic medications are indicated in all young people with a FEP and whether antipsychotic medication can be safely delayed. Furthermore, the relative contribution of psychotic illness and antipsychotic medication in terms of structural brain changes will also be elucidated. The findings will inform clinical practice guidelines.

Enhancing treatment fidelity in psychotherapy research: novel approach to measure the components of cognitive behavioural therapy for relapse prevention in first-episode psychosis.

OBJECTIVES: Establishing treatment fidelity is one of the most important aspects of psychotherapy research. Treatment fidelity refers to the methodological strategies used to examine and enhance the reliability and validity of psychotherapy. This study sought to develop and evaluate a measure specifically designed to assess fidelity to the different therapeutic components (i.e. therapy phases) of the individual intervention of a psychotherapy clinical trial (the EPISODE II trial). METHOD: A representative sample of sessions stratified by therapy phase was assessed using a specifically developed fidelity measure (Relapse Prevention Therapy-Fidelity Scale, RPT-FS). Each RPT-FS subscale was designed to include a different component/phase of therapy and its major therapeutic ingredients. RESULTS: The measure was found to be reliable and had good internal consistency. The RPT-FS discriminated, almost perfectly, between therapy phases. The analysis of the therapeutic strategies implemented during the intervention indicated that treatment fidelity was good throughout therapy phases. While therapists primarily engaged in interventions from the appropriate therapeutic phase, flexibility in therapy was evident. CONCLUSIONS: This study described the development of a brief, reliable and internally consistent measure to determine both treatment fidelity and the therapy components implemented throughout the intervention. This methodology can be potentially useful to determine those components related to therapeutic change.

Moderated Online Social Therapy: A Model for Reducing Stress in Carers of Young People Diagnosed with Mental Health Disorders.

Family members caring for a young person diagnosed with the onset of mental health problems face heightened stress, depression, and social isolation. Despite evidence for the effectiveness of family based interventions, sustaining access to specialist family interventions is a major challenge. The availability of the Internet provides possibilities to expand and sustain access to evidence-based psychoeducation and personal support for family members. In this paper we describe the therapeutic model and the components of our purpose-built moderated online social therapy (MOST) program for families. We outline the background to its development, beginning with our face-to-face EPISODE II family intervention, which informed our selection of therapeutic content, and the integration of recent developments in positive psychology. Our online interventions for carers integrate online therapy, online social networking, peer and expert support, and online social problem solving which has been designed to reduce stress in carers. The initial version of our application entitled Meridian was shown to be safe, acceptable, and feasible in a feasibility study of carers of youth diagnosed with depression and anxiety. There was a significant reduction in self-reported levels of stress in caregivers and change in stress was significantly correlated with use of the system. We have subsequently launched a cluster RCT for caregivers with a relative diagnosed with first-episode psychosis. Our intervention has the potential to improve access to effective specialist support for families facing the onset of serious mental health problems in their young relative.

A randomized controlled trial of bibliotherapy for carers of young people with first-episode psychosis.

Caring for young people with first-episode psychosis (FEP) is challenging and can adversely affect carer well-being, with limited evidence-based support materials available. We aimed to examine whether completion of a self-directed problem-solving bibliotherapy among carers of young people with FEP led to a better experience of caring, less distress and expressed emotion, and better general health than carers who only received treatment as usual (TAU). A randomized controlled trial was conducted across two early-intervention psychosis services in Melbourne, Australia. A total of 124 carers were randomized to problem-solving bibliotherapy intervention (PSBI) or TAU and assessed at baseline, 6-week and 16-week follow-up. Intent-to-treat analyses were carried out and indicated that recipients of PSBI had a more favorable experience of caring than those receiving TAU, and these effects were sustained at both follow-up time points. Across the other measures, both groups demonstrated improvements by week 16, although the PBSI group tended to improve earlier. The PSBI group experienced a greater reduction in negative emotional evaluations of the need to provide additional support to young people with FEP than the TAU group by week 6, while the level of psychological distress decreased at a greater rate from baseline to 6 weeks in the PSBI compared with the TAU group. These findings support the use of problem-solving bibliotherapy for first-time carers, particularly as a cost-effective adjunct to TAU.

A randomized controlled trial of relapse prevention therapy for first-episode psychosis patients: outcome at 30-month follow-up.

The effectiveness of a novel 7-month psychosocial treatment designed to prevent the second episode of psychosis was evaluated in a randomized controlled trial at 2 specialist first-episode psychosis (FEP) programs. An individual and family cognitive behavior therapy for relapse prevention was compared with specialist FEP care. Forty-one FEP patients were randomized to the relapse prevention therapy (RPT) and 40 to specialist FEP care. Participants were assessed on an array of measures at baseline, 7- (end of therapy), 12-, 18-, 24-, and 30-month follow-up. At 12-month follow-up, the relapse rate was significantly lower in the therapy condition compared with specialized treatment alone (P = .039), and time to relapse was significantly delayed for those in the relapse therapy condition (P = .038); however, such differences were not maintained. Unexpectedly, psychosocial functioning deteriorated over time in the experimental but not in the control group; these differences were no longer statistically significant when between-group differences in medication adherence were included in the model. Further research is required to ascertain if the initial treatment effect of the RPT can be sustained. Further research is needed to investigate if medication adherence contributes to negative outcomes in functioning in FEP patients who have reached remission, or, alternatively, if a component of RPT is detrimental.

Family outcomes from a randomized control trial of relapse prevention therapy in first-episode psychosis.

OBJECTIVE: We have previously reported that our combined individual and family cognitive-behavioral therapy (CBT) relapse prevention therapy (RPT) was effective in reducing relapse rates compared to treatment as usual (TAU) within a specialist program for young, first-episode psychosis patients who had reached remission on positive symptoms. Here, we report the outcomes for family participants of DSM-IV-diagnosed first-episode psychosis patients recruited between November 2003 and May 2005 over a 2.5-year follow-up period. The primary hypothesis was that, compared to family members receiving TAU, family participants who received RPT would have significantly improved appraisals of stressors related to caregiving. Secondary hypotheses were that RPT would be associated with reduced expressed emotion and improved psychological distress. METHOD: Family members were assessed at baseline and at 7-month, 12-month, 18-month, 24-month, and 30-month follow-up on appraisal of caregiving, expressed emotion, and psychological distress using the Experience of Caregiving Inventory, The Family Questionnaire, and the General Health Questionnaire of 28 Items, respectively. The family component of RPT was based on family behavioral therapy for schizophrenia with a specific focus on psychoeducation and CBT for relapse prevention. RESULTS: Thirty-two families received RPT, and 31 families received TAU. There were significant group effects for aspects of the appraisal of caregiving, including negative symptoms, positive personal experiences, and total positive score on the Experience of Caregiving Inventory. Time effects were evident for emotional overinvolvement and for aspects of the appraisal of caregiving. There were no significant effects for psychological distress. CONCLUSIONS: The relatives of patients who received RPT perceived less stress related to their relative's negative symptoms and an increase in perceived opportunities to make a positive contribution to the care of their relative compared to carers in the TAU condition. Cognitive-behavioral therapy for relapse prevention showed promise in improving the experience of caregiving for family members of first-episode psychosis patients over a 2.5-year follow-up period.

A randomized controlled trial of relapse prevention therapy for first-episode psychosis patients.

OBJECTIVE: Patients with first-episode psychosis are responsive to acute-phase treatments, but relapse rates are high. This study aimed to evaluate the effectiveness of a psychosocial treatment designed to prevent the second episode of psychosis compared with standardized early psychosis care. METHOD: In a randomized controlled trial, conducted at the Early Psychosis Prevention and Intervention Centre and Barwon Health, Australia, a multimodal individual and family cognitive-behavioral therapy for relapse prevention was compared with standardized case management within a specialist early psychosis service. Patients aged 15 to 25 years with a first episode of a DSM-IV psychotic disorder were recruited between November 2003 and May 2005. The main outcome measures were the number of relapses and time to first relapse. RESULTS: Forty-one first-episode psychosis patients were randomly assigned to the relapse prevention therapy (RPT) and 40 to standardized case management. At the 7-month follow up, the relapse rate was significantly lower in the therapy condition compared to treatment as usual (p = .042) and time to relapse was significantly longer for the RPT condition (p = .03). The number needed to treat was 6 over 7 months. CONCLUSIONS: Interim findings suggest that RPT provided within a specialist early psychosis program was effective in reducing relapse in early psychosis when compared with standardized early psychosis case management.
