There is increasing pressure on therapists to provide details of structured assessments and to report therapy outcomes to funders, employers and co-workers. This edited volume provides a series of case studies, with varied client groups, giving arts therapists an accessible introduction to assessment and outcome measures that can be easily incorporated into their regular practice. The book provides demonstrations, within a practice-based evidence framework, of how measures can be tailored to the individual client's needs. The case studies show assessment and outcome models for music therapy, art therapy and dramatherapy used with a range of client groups including people with intellectual disabilities, Autism Spectrum Disorders, Multiple Sclerosis and Parkinson's Disease and those suffering from depression, Post-Traumatic Stress Disorder or coping with bereavement.
