Handbook of Clinical Psychology Competencies describes the core competency areas in providing psychological services relevant to practitioners as well as clinical researchers. It covers assessment and conceptualization of cases, the application of evidence-based methods, supervision, consultation, cross-cultural factors, and ethics.

This three-volume handbook provides detailed descriptions of competence levels and describes the developmental trajectory required to reach the highest of these levels. It features contributions by experts in each area.

Each chapter in the first volume follows a similar format, including an overview, basic competencies, and expert competencies, which facilitates easy comparison across chapters. In addition, all the material is illustrated with case examples. Subsequent volumes feature a similarly structured format that includes maintenance factors, mechanisms of change, evidence-based treatment approaches, and a focus on the transition from basic skills to expert functioning.
