ABSTRACT: Case study research has been used relatively often in school and other applied areas of psychology. As traditionally conceived, case study investigation refers to the relatively uncontrolled and subjectively described study of a single case. However, case studies need not be restricted to this form of methodology. Several different types of case studies are reviewed in this paper including non-therapeutic, assessment, and therapeutic/intervention case studies.Case studies can be improved by taking into account numerous methodological factors,including repeated measurement of objective data, planning the treatment, chronicity of the case, size, and impact of effects, the number and diversity of subjects, standardization, and monitoring the integrity of both the independent and dependent variables, employing some type of formal design and data analysis, examining the social validity of outcomes, assessing generalization and maintenance of treatment effects. Several example studies are reviewed in the context of these considerations and recommendations are made for future case study research in school psychology.
