Designing home environments for health and wellness is a crucial strategy for disease prevention and health promotion. Yet, there is not a tool to evaluate perceptions regarding home design for health and wellness. This study aimed to develop and validate a new instrument to measure people's perceptions regarding the concept of DWELL: Design for WELLness in the home environment. We developed a short 5-item online questionnaire to detect changes in knowledge, awareness, engagement and self-efficacy regarding DWELL. The instrument was validated in an online study. Of the 613 mothers who answered the questionnaire initially, 397 answered the questionnaire a second time. Factor analysis and Cronbach's alpha indicated that all five DWELL questions load into one single factor (the model explained 61.84% of total variance), and measure a reliable scale of the same construct, with high levels of internal consistency (Cronbach's α = 0.85) at both first and second administrations. Spearman correlations between DWELL first and second administrations of the questionnaire indicated moderate-to-high test-retest reliability (0.55-0.70, p < 0.001). DWELL was found to be a valid tool which fills a gap in the public health literature. This measure serves as a free and convenient online instrument to gain insights regarding the effect of modifying environments for disease prevention and health promotion. The tool may be used to assess perceptions in the conditions leading wellness promotion in the home.
