The relationship between occupational performance and stress of subjects discharged to home:

Using SOPI and heart rate variability analysis

Abstract

The purpose of this study was to clarify the relationship between work participation (evaluated using SOPI:Self-completed Occupational Performance Index) and stress (evaluated using autonomic nerve activity) in 26 rehabilitated users who returned home. The analysis confirmed the correlation coefficient between the stress index and SOPI. Subsequently, a multiple regression analysis (stepwise method) was performed using the stress index as a dependent variable, and the three areas of SOPI as explanatory variables. Moreover, a multiple regression analysis (stepwise method) was performed with three aspects of SOPI work performance as explanatory variables. Significant correlation was found between stress index and SOPI (r＝-0.495 [p＝0.010]). As a result of the multiple regression analysis, “leisure activity” (R²＝0.224, standardization coefficient β＝-0.473, p＝0.015) and “work control” were extracted as factors related to stress reduction (R²＝0.262, standardization coefficient β＝-0.511, p＝0.008).
