How can therapists help clients reflect more deeply on their own—and other people's—thoughts and emotions? How can the therapeutic relationship be leveraged effectively to create change? This concise book guides therapists of any orientation to incorporate innovative mentalization-based strategies into assessment and intervention. Complex ideas are clearly explained and illustrated with extensive session transcripts and vignettes. Ways to help clients struggling with dysregulated emotions and behavior are highlighted. Compelling topics include the role of mentalization difficulties in personality disorders, special concerns in working with adolescents, and how clinicians can improve their own mentalizing capacities.
