Introduction: Home modifications play a crucial role in supporting independence, safety and participation for older adults and individuals with disabilities. While home modification services are widely implemented, limited research has explored how client satisfaction with the home modification process and outcomes. This study examined clients’ satisfaction levels and key factors influencing satisfaction with home modification services.

Method: An explanatory sequential mixed-methods design was used to collect quantitative data from 45 participants using the Post Modification Satisfaction Questionnaire (PMSQ). One-way ANOVAs examined associations between client satisfaction and participants' age, modification type, cost and Modified Barthel Index (MBI) scores. Qualitative data were obtained from 12 participants using semi-structured interviews which were thematically analysed to explore factors influencing
satisfaction.

Results: Modification type (major vs. minor), cost and MBI scores were not significantly related to satisfaction on the PMSQ, although age was (p < 0.002), with younger participants (under 60) reporting lower satisfaction (M=74, SD21.85). Thematic analysis identified communication as an overarching factor influencing satisfaction, with three key themes: 1) involvement in decision-making, 2) being informed about funding processes, and 3) communication with builders.

Conclusion: Whilst modification type, cost and MBI scores did not strongly influence satisfaction, communication throughout the process emerged as a critical factor. This study underscores the importance of client-centred communication strategies to enhance satisfaction with home modification services. Age-related differences in satisfaction warrant further investigation.
