RESUMO
BACKGROUND: This article explores the effectiveness of development of the Lo's Healthy and Happy Lifestyle Scale (LHHLS), which is an evaluative tool that monitors the resilience of the Taiwan population in times of such COVID-19 epidemic. Also, to verify factors of resilience, namely the reliability and validity of self-efficacy and positive thinking, and establishment of a prospective norm analysis. METHOD: The study mainly applied Explorative Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA) to develop LHHLS and establish the reliability and validity of the tool's structure, verify norm analysis and the reliability of data from each question using Cronbach's alpha. RESULTS: According to statistics, LHHLS has a good factorial effectiveness and relatively high reliability, with factor reliability analyses where Cronbach's alpha lies between 0.83 to 0.94. The 14 questions in the LHHLS has a total variance of 67.04%. The tool includes two sub-assessments that are theoretically and statistically appropriate: mental health/self-efficacy and positive thinking. CONCLUSION: The tool LHHLS can be applied to populations affected by COVID-19. With participants' self-awareness of mental health state and state of happy living, this tool is valid and reliable in assessing and evaluating the resilience of such participants against times of COVID-19. This study can become future use for epidemic prevention communities in monitoring residents' healthy living and changes in their resilience. Also, can become a reference standard for interventions to reduce the impacts populations' happy and healthy living, in times of biological disasters.
