Planning research in psychosocial interventions.

A number of research designs have been used to study the efficacy of psychosocial interventions in addictive disorders, including open label studies and randomised controlled trials. Only through a rigorously conducted research, evidence base for effectiveness of a psychosocial intervention can be established. However, research on these interventions are fraught with a number of challenges. It is imperative for researchers to ask appropriate research questions based on sound theoretical understanding of psychiatric disorders, psychosocial interventions and research designs. This would help in choosing the less studied, relevant areas for in depth study as well as in using pragmatic, realistic research designs. Defining intervention clearly is as crucial, as is its uniform implementation across various treatment arms. In addition, tapping the mediators, moderators and confounders of treatment using appropriate methods while assessing the factors that directly impact the outcome is important to determine actual effects of psychosocial intervention. Barriers at different stages must be gauged proactively and dealt with, wherever possible.
