ABSTRACT
Research into psychosocial treatment strategies exists at varying stages of development, some modalities having been studied more often and with better-designed ran domized controlled trials. The majority of the randomized controlled trials reviewed assumed that optimal antipsy chotic medication management was provided. From the available literature, whenever possible, we will address the following questions. What is the efficacy of the specific in tervention for the primary outcome measure? For second ary outcomes? Is a particular kind of psychosocial inter
vention more efficacious for certain outcomes? (If so, what is the evidence for an “active ingredient”?). What evidence exists for effectiveness and transferability, i.e., effective ness in more usual clinical settings? What data exist re garding cost-effectiveness?
