This text is a virtual handbook of classic mistakes to anticipate, work through, and grow from. It identifies, discusses and re-frames classic mistakes that beginning interviewers and clinicians are likely to make in practice by illuminating a myriad of mistakes through the use of first-hand vignettes, in-text exercises, and a systems framework. This book uses a strengths-perspective, and can serve as a companion text or as a stand-alone primer because of its elaboration of the phases, principles, strategies and methods used in the helping process.
