In order to treat adolescent depression, a number of empirically supported treatments (ESTs) have been developed from both the cognitive behavioral therapy (CBT) and interpersonal psychotherapy (IPT-A) frameworks. Research has shown that in order for these treatments to be implemented in routine clinical practice (RCP), effective therapist training must be generated and provided. However, before such training can be developed, a good understanding of the therapist competencies needed to implement these ESTs is required. Sburlati et al. ("Clin Child Fam Psychol Rev" 14:89-109, 2011) developed a model of therapist competencies for implementing CBT using the well-established Delphi technique. Given that IPT-A differs considerably to CBT, the current study aims to develop a model of therapist competencies for the implementation of IPT-A using a similar procedure as that applied in Sburlati et al. ("Clin Child Fam Psychol Rev" 14:89-109, 2011). This method involved: (1) identifying and reviewing an empirically supported IPT-A approach, (2) extracting therapist competencies required for the implementation of IPT-A, (3) consulting with a panel of IPT-A experts to generate an overall model of therapist competencies, and (4) validating the overall model with the IPT-A manual author. The resultant model offers an empirically derived set of competencies necessary for effectively treating adolescent depression using IPT-A and has wide implications for the development of therapist training, competence assessment measures, and evidence-based practice guidelines. This model, therefore, provides an empirical framework for the development of dissemination and implementation programs aimed at ensuring that adolescents with depression receive effective care in RCP settings. Key similarities and differences between CBT and IPT-A, and the therapist competencies required for implementing these treatments, are also highlighted throughout this article.

This paper describes the process of modifying and transporting an evidence-based treatment, Interpersonal Psychotherapy for Depressed Adolescents (IPT-A), from a university setting to school-based health clinics. It addresses conceptual issues involved in the shift from efficacy to effectiveness research as well as operational issues specific to the transport of IPT-A into school-based health clinics. Consideration is given to the rationale for an IPT-A effectiveness study, methodological concerns, and the timing of the move from the "lab" to the community. The authors identify challenges and barriers to initiating effectiveness and transportability research and provide suggestions for overcoming these barriers. Recommendations for conducting research in school-based practice settings are provided.
