The first part of this book describes and explains the basic concepts of neurocognition, social cognition, and social competency that are now allowing us a better understanding of schizophrenia. Current treatment approaches and empirical support for them are also discussed. The core of the book is a clear and structured description of the five subprograms making up IPT: # Cognitive Differentiation # Social Perception # Verbal Communication # Social Skills # Interpersonal Problem-Solving Clinicians learn step by step how to apply the therapy techniques and to select the appropriate therapy materials (described in detail in practical appendices). The book also provides practical advice about dealing with group processes and individual dyadic situations. Differential indications, assessment, therapy planning and evaluation are presented. Therapists will also learn how to use IPT within multimodal therapy and rehabilitation efforts (case management; implementation of IPT). The final part of the book provides an overview of further developments of IPT: Integrated Neurocognitive Therapy (INT), conceptualized mainly for outpatients with better social functioning, and specific social skills programs for residential, vocational, and recreational rehabilitation (WAF).
