Case analyses are an excellent tool for effective case management and quality assurance, and they represent the gold standard for applied research in the psychosocial field. This volume brings together the essential components needed for the planning, execution, and interpretation of psychosocial case analyses: foundational knowledge in scientific theory, research designs, data collection methods, and statistical analysis techniques. It also presents components that are rarely discussed in detail in other works on case research: goal achievement analysis, outpatient assessment, the psychometric case approach, and graphical methods. All steps of the process are explained and illustrated with numerous didactic examples from the psychosocial field. Detailed case studies illustrate the approach and its application.
