How do we know if mental health services work? What are the best ways to measure the outcomes of care for people with mental health problems? This book contains five practical scales for assessing the outcomes of mental healthcare. They are the European versions of: Camberwell Assessment of Need (for unmet and met needs) Client Socio-demographic and Service Receipt Inventory (for service costs) Involvement Evaluation Questionnaire (for impact of care on family members) Lancashire Quality of Life Profile (for quality of life) Verona Service Satisfaction Scale (for service satisfaction). Each scale has been standardised (in Danish, Dutch, English, Italian and Spanish), and has been shown to be reliable and valid in all these European languages. The book contains full details of the development of these scales, manuals for their use, the scales themselves and instructions on how to use the results. These new measures will be invaluable to all those in research, evaluation, audit and management who have an interest in evidence-based policy and practice in mental healthcare.
