New evidence from clinical research seems to arrive each day, confirming the link between effective clinical supervision and positive client outcomes. As a result considerable efforts have been invested in training clinicians in ways that are measurable and systematic, and that produce the best possible outcomes for clients, supervisees, and supervisors alike.This concise text describes a trans-theoretical approach that has been the gold standard in supervisory practice for nearly two decades. The authors show readers how to identify, assess, and track the knowledge, specific skills, broad attitudes, and human values that undergird a series of professional competencies spanning the breadth of clinical practice.Case examples illuminate the supervisory give-and-take as trainees develop competence in areas such as professional values, sensitivity to individual and cultural differences, ethical and legal standards, self-care, scientific knowledge and methods, applying evidence-based practice, and more. From practicum, to internship and general practice, the competency-based approach offers clear training goals that organize and focus the supervisor's attention where it's needed most.This book also includes dialogue from the authors' supervision session with a real trainee as shown in the DVD Competency-Based Supervision.
