title: Methodological problems encountered in research with psychiatric inpatients: a case example.
abstract: In this article, problems associated with several methods commonly employed in research with psychiatric inpatients are discussed and the implications that these problems have for the validity of research with this population are explored, using an investigation of the relationship between moral reasoning and aggression among psychiatric inpatients as a case example. Specific issues examined include the adequacy of hospital records for diagnosing patients, the difficulty of determining when it is appropriate to approach recently admitted patients for research, and problems in the measurement of behavioral and psychological variables such as aggression and moral reasoning. Suggestions and recommendations for addressing these issues in future research are offered.
