Increasingly, psychologists are being enlisted to provide consultation in clinical, health, corporate, and community settings, although many have received only minimal training in consultation. This volume provides a comprehensive foundation to develop or enhance consultation practice. Consultation is a distinct professional practice with goals and functions different from direct clinical service or clinical supervision. While all consultation settings require certain basic competencies, each setting requires additional unique ones. Thus, the opening chapters of this book introduce a competency-based, multicultural, and ethical approach to consultation that is relevant to all contexts, while subsequent chapters build on this foundation and describe the knowledge, skills, and attitudes necessary for consultation in a variety of specific contexts. These include medical, pediatric, forensic, school, corporate, leadership, family, religious, police, and military settings. Both students and practicing psychologists will benefit from this essential guide.
