Cognitive behavioral therapy is an effective approach to the treatment of depressive disorders within schools, due to its demonstrated efficacy, as well as its availability in manualized treatment form. When implemented by therapists with inadequate training, the treatment is often stilted, less engaging for participants, and aimlessly guided through rigid adherence to the treatment manual. The transportability of such interventions to schools will be discussed, highlighting challenges that school psychologists may face, along with addressing important aspects for the successful implementation of treatments. The ACTION treatment program, a highly effective cognitive behavioral intervention for depressed youth, is provided as an example of one such program. Primary treatment components of ACTION are described along with subtleties to effectively train school psychologists who intend to treat depressed youth. The importance of improved training for school psychologists to become effective at implementing cognitive behavioral interventions is highlighted.
