It has been suggested that cultural differences can influence the process of Cognitive Behaviour Psychotherapy, and therefore therapy might need adapting to the cultural needs of a given country. Our group has adapted Cognitive Therapy for depression in Pakistan (F. Naeem, Ayub, Gobbi, & Kingdon, 2009; F. Naeem, Gobbi, Ayub, Kingdon, & others, 2010; Farooq Naeem, Ayub, Kingdon, & Gobbi, 2012; Farooq Naeem, Gobbi, Ayub, & Kingdon, 2009) , which was found to be effective in a small trial (Farooq Naeem, Waheed, Gobbi, Ayub, & Kingdon, 2011). Same methodology was useed to adapt CBT for schizophrenia for local use (Naeem et al, under review). A small pilot found it to be effective in inpatient settings. (Habib et al, under review). This is a RCT to test the effectiveness of Culturally adapted CBT for psychosis (CaCBTp).
