Critical Events in Psychotherapy Supervision helps supervisors understand the dilemmas they most frequently encounter when supervising psychotherapist trainees. Such dilemmas may include ambiguity about roles, misunderstandings related to cultural background and gender, problematic attitudes and behavior, skill deficits, countertransference, and sexual attraction to clients. Resolving these difficulties effectively is particularly important in the supervisor-supervisee relationship, because doing so models positive ways of handling interactions with clients.
