Culturally adapted psychosocial interventions (CaPSI) for early psychosis in a low-resource setting: study protocol for a large multi-center RCT.

BACKGROUND: Psychosis treatment guidelines recommend cognitive behaviour therapy (CBT) and family intervention (FI), for all patients with first episode psychosis (FEP), though guidance borrows heavily from literature in adults from high income countries. To our knowledge, there are few randomized controlled trials (RCTs) examining the comparative effect of these commonly endorsed psychosocial interventions in individuals with early psychosis from high-income countries and no such trials from low and middle-income countries (LMICs). The present study aims to confirm the clinical-efficacy and cost-effectiveness of delivering culturally adapted CBT (CaCBT) and culturally adapted FI (CulFI) to individuals with FEP in Pakistan. METHOD: A multi-centre, three-arm RCT of CaCBT, CulFI, and treatment as usual (TAU) for individuals with FEP (n = 390), recruited from major centres across Pakistan. Reducing overall symptoms of FEP will be the primary outcome. Additional aims will include improving patient and carer outcomes and estimating the economic impact of delivering culturally appropriate psychosocial interventions in low-resource settings. This trial will assess the clinical-efficacy and cost-effectiveness of CaCBT and CulFI compared with TAU in improving patient (positive and negative symptoms of psychosis, general psychopathology, depressive symptoms, quality of life, cognition, general functioning, and insight) and carer related outcomes (carer experience, wellbeing, illness attitudes and symptoms of depression and anxiety). CONCLUSIONS: A successful trial may inform the rapid scale up of these interventions not only in Pakistan but other low-resource settings, to improve clinical outcomes, social and occupational functioning, and quality of life in South Asian and other minority groups with FEP. TRIAL REGISTRATION: NCT05814913.

Willingness to pay for treated mosquito nets in Surat, India: the design and descriptive analysis of a household survey.

For willingness to pay (WTP) studies to have an appropriate impact on policy making, it is essential that the design and analysis are undertaken carefully. This paper aims to describe and justify the design of the survey tool used to assess hypothetical WTP for treated mosquito nets (TMN) in rural Surat, India and report its findings. Results from qualitative work were used as an input for developing the WTP questionnaire. A total of 1200 households belonging to 80 villages in rural Surat were selected for the study. A bidding format was used to elicit WTP values, using three different starting bids. The scenario was constructed in a way to reduce the possibility of respondents acting strategically. The response rate was 100%. About 79% of the respondents were willing to buy TMNs and the mean WTP was Rs57. Descriptive results of economic and other taste and preference variables are also presented, which include preventive measures used by households and treatment seeking behaviour for malaria. It is observed that WTP as well as demographic variables and prevention methods differ significantly across arms of the trial. This paper suggests that policy-makers could use the evidence following further analysis, along with information on costs of implementation, to ascertain the levels of subsidy that may be needed at different levels of coverage.
