Abstract

OBJECTIVE:

To identify psychometric properties of the Home Safety Self-Assessment Tool (HSSAT) to prevent falls in community-dwelling older adults.

METHOD:

We tested content validity, test-retest reliability, interrater reliability, construct validity, convergent and discriminant validity, and responsiveness to change.

RESULTS:

The content validity index was .98, the intraclass correlation coefficient for test-retest reliability was .97, and the interrater reliability was .89. The difference on identified risk factors between the use and nonuse of the HSSAT was significant (p = .005). Convergent validity with the Centers for Disease Control and Prevention Home Safety Checklist was high (r = .65), and discriminant validity with fear of falling was very low (r = .10). The responsiveness to change was moderate (standardized response mean = 0.57).

CONCLUSION:

The HSSAT is a reliable and valid instrument to identify fall risks in a home environment, and the HSSAT booklet is effective as educational material leading to improvement in home safety.
