Brief culturally adapted CBT for psychosis (CaCBTp): A randomized controlled trial from a low income country

Abstract

Evidence for the effectiveness of Culturally adapted CBT for psychosis in Low And Middle Income Countries (LAMIC) is limited. Therefore, brief Culturally adapted CBT for psychosis (CaCBTp) targeted at symptoms of schizophrenia for outpatients plus treatment as usual (TAU) is compared with TAU. A total of 116 participants with schizophrenia were recruited from 2 hospitals in Karachi, Pakistan, and randomized into two groups with 1: 1 allocation (CaCBTp plus TAU = 59, TAU = 57). A brief version of CaCBTp (6 individual sessions with the involvement of main carer, plus one session for the family) was provided over 4 months. Psychopathology was measured using Positive and Negative Syndrome Scale of Schizophrenia (PANSS), Psychotic Symptom Rating Scales (PSYRATS), and the Schedule for Assessment of Insight (SAI) at baseline and end of therapy. Participants in treatment group, showed statistically significant improvement in all measures of psychopathology at the end of the study compared with control group. Participants in treatment group showed statistically significant improvement in Positive Symptoms (PANSS, Positive Symptoms Subscale; p = 0.000), Negative Symptoms (PANSS, Negative Symptoms subscales; p = 0.000), Delusions (PSYRATS, Delusions Subscale; p = 0.000), Hallucinations (PSYRATS, Hallucination Subscale; p = 0.000) and Insight (SAI; p = 0.007). The results suggest that brief, Culturally adapted CBT for psychosis can be an effective treatment when provided in combination with TAU, for patients with schizophrenia in a LAMIC setting. This is the first trial of CBT for psychosis from outside the western world. These findings need replicating in other low and middle income countries
