culturally adapted psychosocial interventions for early psychosis in a low-resource setting

Conditions: Psychosis

Summary: primary aims: to determine the clinical efficacy of culturally adapted cognitive behavioral therapy (cacbt) and culturally adapted family intervention (culfi) compared to treatment as usual (tau) on reducing overall symptoms of psychosis in patients with first episode psychosis (fep) in pakistan. secondary aims: 1. to determine the efficacy of cacbt and culfi compared to tau on positive and negative symptoms of psychosis, general psychopathology, depressive symptoms, quality of life, general functioning, and insight in patients with fep in pakistan. 2. to determine the efficacy of cacbt and culfi compared to tau on improving carer experience, carer wellbeing, carer illness attitudes and symptoms of depression and anxiety in family and carers of patients with fep in pakistan. 3. to determine the comparative effect of cacbt and culfi in improving patient and carer related outcomes in individuals with fep in pakistan. 4. to estimate the economic impact of delivering culturally appropriate psychosocial interventions in low-resource settings 5. to explore delivery and reach of each intervention, tolerability of intervention components, acceptability of interventions, understanding mechanism of change and developing an understanding of barriers and facilitators to future adoption using process evaluation. study design and setting: this will be a multi-centre, assessor masked, individual, three-arm randomised controlled trial (rct). sample size: the study aims to recruit a total of n=390 participants with fep

family intervention (fi) and cognitive behavior therapy (cbt) are among the most efficacious psychosocial interventions to prevent relapse in schizophrenia. however, there is limited evidence from lmics that supports the clinical efficacy and cost-effectiveness of delivering these psychosocial interventions to individuals with fep. we aim to determine the clinical efficacy and cost-effectiveness of culturally adapted cognitive behavioral therapy (cacbt) and culturally adapted family intervention (culfi) compared to tau in reducing overall symptoms of psychosis in individuals with fep in pakistan. the study will include 390 participants with fep from psychiatric units of hospitals and community settings in ten centres (i.e. karachi, lahore, rawalpindi, hyderabad, qambar shahdakot, shaheed benazirabad, sukkur, peshawar, quetta and multan). consented participants meeting eligibility criteria will be randomised in a 1:1:1 allocation to cacbt + tau, culfi + tau or tau alone. participants in cacbt intervention group will receive 12-weekly one-to-one sessions. participants in culfi group will receive 10-weekly one-to-one sessions. each cacbt and culfi session will last for approximately 1 hour. sessions will be delivered by trained psychologists who will receive regular weekly supervision to maintain fidelity. assessments will be carried out at baseline, months 3, 6, and 12 by trained, blinded assessors. . process evaluation will help to build the implementation knowledge base for proposed interventions across study settings. we will conduct economic evaluations (i.e., the cost-effectiveness and cost-utility analyses) of the cacbt and culfi interventions, as add-on to tau.
