Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Participants will be adults attend primary health care centers and indicating moderate distress & impaired functioning. Participants wishing to participate will be randomly allocated according to a random numbers system administered by an individual who independent of the study and who works at a site that is distant from the treatment centre.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomization will be conducted by a process of minimization stratified by primary health care center.

Efficacy
Statistical methods / analysis
Power calculations suggest a minimum sample size of 133 participants per group (power =.95, alpha = .05, 2-sided). Taking into account an expected 30% attrition at 3 months follow-up, we aim to include a total number of 346 participants (173 in each group, with an approximate equal number of men as women). The thrust of analyses will be using hierarchical linear models (HLM) to investigate the relative effects of the treatments. Analyses will be conducted using Mplus (version 7.11). The benefit of this approach is that it presumes intent-to-treat analyses as HLM allows the number of observations to vary between participants and effectively handles missing data by using the maximum likelihood estimator, which provides the optimal estimates of model parameter values and standard errors. The Level 1 model will represent within-patient change over time, and the Level 2 model will predict variation in within-patient change over time and encompass between-patient variables (treatment condition, injury characteristics, gender). Primary measures will comprise the HADS and WHODAS.

Summary
Brief summary
The rationale of the study is to evaluate the efficacy of a low intensity intervention to reduce mental health problems in people in low-resources settings. This study compares the relative efficacy of (a) Problem Management Plus, and (b) Enhanced Treatment as Usual. It is hypothesised that Problem Management Plus will lead to greater symptom reduction than Enhanced Treatment as Usual.
