The purpose of this study was to determine if recommendations made as a result of the administration of the Cougar Home Safety Assessment Version 4.0 (CHSA 4.0) were effective in causing older residents to make environmental safety modifications in their homes. Initial data were collected during the administration of the CHSA 4.0 in the homes of 40 older people in four northeastern states. After completing the initial assessments, the researchers provided the participants with recommendations for improving the environmental safety of their homes. Approximately one month later, each home was reassessed with the CHSA 4.0. Overall, improvement in environmental safety was demonstrated in the homes with the greatest increases being in fire safety, emergency phone number placement, and bathroom safety. A t-test demonstrated a significant gain in compliance (t = 7.8, p < .001) by comparing the difference between the mean initial and reassessment home safety scores. A very large effect size (Cohen’s d = 1.7) was also found, indicating a high magnitude of difference between initial and reassessment safety ratings. The assessment proved to be beneficial in increasing the environmental safety of homes
