The diagnostic accuracy of questions about past experiences of being mechanically restrained in a population of psychiatric patients.

Information about stressful life experiences obtained from patients during diagnostic interviews is an important foundation for clinical decision making. In this study self-reports from 115 committed psychiatric patients of experiences of mechanical restraint were compared with medical records. The sensitivity of patient self-reports was 73% (11/15) and the specificity was 92% (92/100). No clear relationship between psychiatric symptoms and reliability of self-reports was identified. The results highlight the subjective qualities of narratives about past experiences.
