- Pakistan Institute of Living and Learning
- Brief 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
- Detailed Description
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.

Group Intervention Description CaCBT for psychosis CaCBT for psychosis CaCBT is a culturally adapted psychosocial intervention for people with early psychosis that comprises of 12 sessions. These sessions are conducted individually on a weekly basis and last 45-60 minutes CulFI Intervention Culturally adapted Family Intervention (CulFI) for psychosis CulFI is a culturally adapted psychosocial intervention delivered over 10 sessions of 40-60 minutes, weekly for the first 8 weeks and fortnightly for the remaining 4 weeks. Sessions are delivered to patients and their carers, though patient participation in sessions is not necessary.
- Primary Outcome Measures
Name Time Method Positive and Negative Syndrome Scale Change in scores from baseline to months 3, 6, and 12 The PANSS is a structured interview use to evaluate the prevalence and severity of the positive, negative and general psychiatric symptoms of schizophrenia. The higher the score the greater symptoms severity. potential ranges are 7 to 49 for the Positive and Negative Scales, and 16 to 112 for the General Psychopathology Scale.
- Secondary Outcome Measures
Name Time Method Calgary Depression Scale for Schizophrenia Change in scores from baseline to months 3, 6, and 12 The CDSS is a 9-items scale which evaluates depression in individuals with psychosis. The minimum score is 0 and maximum 30.Higher scores indicate greater depressive severity
EuroQol-5 Dimensions Change in scores from baseline to months 3, 6, and 12 EuroQol-5D (EQ- 5D) will be used to assess health-related quality of life over 5 dimensions (mobility, self-care, daily activities, pain-discomfort, anxiety and depression). Higher score indicates better quality of life.
World Health Organization Disability Assessment Scale Change in scores from baseline to months 3, 6, and 12 It is a self-administered questionnaire based on 36 items that measures health and disability. The scoring has three steps: Step 1 - Summing of recoded item scores within each domain. Step 2 - Summing of all six domain scores. Step 3 - Converting the summary score into a metric ranging from 0 to 100 (where 0 = no disability; 100 = full disability
Schedule for Assessment of Insight Change in scores from baseline to months 3, 6, and 12 The Schedule for Assessment of Insight is used to evaluate the three different aspects of insight: treatment compliance, recognition of illness and re-labelling of psychotic phenomena
Experience of Caregiving Inventory Change in scores from baseline to months 3, 6, and 12 The ECI is a thorough measure that assesses the experiences of caring for a family member with severe mental illness
Carer Well-Being and Support Change in scores from baseline to months 3, 6, and 12 The CWS is an instrument to assess the wellbeing and support of a carer
Illness Perception Questionnaire Change in scores from baseline to months 3, 6, and 12 The IPQ is used to evaluate carer beliefs about schizophrenia
Generalized Anxiety Disorder Change in scores from baseline to months 3, 6, and 12 A 7-item scale measuring anxiety. Higher score indicates higher anxiety. Score 0-4: Minimal Anxiety. Score 5-9: Mild Anxiety. Score 10-14: Moderate Anxiety. Score greater than 15: Severe Anxiety.
Patient Health Questionnaire (PHQ-9) Change in scores from baseline to months 3, 6, and 12 The PHQ-9 is a multipurpose instrument for screening, diagnosing, monitoring, and measuring the severity of depression. PHQ-9 total score for the nine items ranges from 0 to 27. Higher score indicates greater depression severity
Cognitive Behaviour Therapy Rating Scale Fidelity will be measured after completion of the intervention ( at 3rd month) Fidelity to the manuals of the interventions will be assessed via recorded sessions using Cognitive Behaviour Therapy Rating Scale
