The Program for Effective Mental Health Interventions in Under-Resourced Health Systems (PREMIUM) sought to develop and assess scalable psychological treatments that are culturally appropriate, affordable, and feasible for delivery by non-specialist health workers and apply these treatments to the two leading mental health disorders: moderately severe to severe depression (the Healthy Activity Program [HAP]) and harmful drinking (Counselling for Alcohol Problems [CAP]). This data collection contains records of adult male/female Primary Health Centres (PHC) attenders (one patient per row) recruited in the trials site between October 28th 2013 and July 30th 2015, and followed-up for outcome assessments until September 30th 2016. It encompasses enrolment, treatment process (including therapy quality), cost-effectiveness, and clinical/other outcome data. Only variables relevant for the analysis of our twelve-month follow-up are presented. The HAP dataset is made available on request, in accordance with ethical constraints outlined in the participant consent agreement. To obtain access, interested parties must complete a data request form or email [email protected] outlining the purpose for which they intend to use the dataset and agree to sign a licence agreement confirming that they will protect participant confidentiality
