Relationship between Interests and Health-Related Quality of Life in Older People

Abstract

Objective: This study examined the relationship between interest responses and health-related quality of life in 324 healthy older Japanese people. Method: Instruments used in this study included the Japanese Interest Checklist for the Elderly (JICE) containing six factors with 25 activities, and the Medical Outcomes Study 36-Item Short Form Health Survey version 2 (SF-36v2). Spearman's rank correlation coefficient was used to test correlations between the three interest parameter scores (interest, current participation and future participation) of the JICE and SF-36v2 scores. Data were analysed for men and women separately to clarify gender-specific differences. Results: Among women, the physical component score in the SF-36v2 correlated significantly and positively with all three interest parameter scores for all factors other than Entertainment Activities in the JICE. Among men, the mental component score in the SF-36v2 correlated significantly and positively with the scores of the three interest parameters for Activities of Daily Living, Pleasurable Outings and Cultural/Educational Activities factors in the JICE. Conclusion: This study identified different correlations between interest responses in activities listed on the JICE and component scores on the SF-36v2 between men and women and demonstrated a new application of interest checklists in the physical domain of the occupational therapy.
