The usefulness of a questionnaire to evaluate daily living performance in psychiatric inpatients: results of cross-sectional and follow-up studies.

: The purpose of this research was to study the usefulness of daily living performance scores (DLPS) in order to indicate the capabilities of inpatients at psychiatric hospitals in performing activities of daily living (ADL). A cross-sectional study was conducted on 44 subjects who were inpatients at psychiatric hospitals in Japan and who responded to a questionnaire about daily living performance. A follow-up survey was conducted 9 months later on 43 patients. These patients were targeted for a study on the relationship between items relating to adverse ambulatory events and DLPS. The results showed a strong correlation between DLPS. From the follow-up survey, the odds ratio (OR) and 95% confidence intervals (CI) for each event experience that produced a 1-point increase in the DLPS were obtained by gender and age-adjusted multiple logistic analysis. The results were as follows: "falling" OR = 0.89, CI (0.805 - 0.977), "stumbling" OR = 0.84, CI (0.733 - 0.977), "indoor ambulatory anxiety" OR = 0.87, CI (0.795 - 0.996), "outdoor ambulatory anxiety" (OR = 0.88, CI (0.795 - 0.996), "injury due to falling" OR = 0.89, CI (0.798 - 0.984) (p < 0.05). The results confirm that DLPS are useful in predicting adverse ambulatory events experienced by patients in psychiatric hospitals.
