Abstract
BACKGROUND: Nurses' resilience in the care of patients with Coronavirus Disease 2019 (COVID-19) is essential. This study aimed to develop and validate an instrument for assessing nurses' resilience control resources in the COVID-19 pandemic. METHODS: In this qualitative study, with a conventional content analysis based on a literature review and semi-structured interviews conducted with 20 nurses, the initial draft of the instrument was prepared in different aspects based on a 5-point scale. The instrument's face validity and content validity were examined in 15 nurses and 15 experts, and construct validity was obtained in 482 nurses using the available sampling method. Data were analyzed in SPSS software Version 24 using indexes and analytic tests. RESULTS: Out of 54 items, 18 items were confirmed by the expert panel and the items had content validity ratio and content validity index scores higher than 0.79. According to the results of an exploratory factor analysis, this tool has 4 dimensions: God, chance, internal locus of control, and powerful others. They accounted for 48.06% of the total variance. CFA showed the indices confirmed the model fit (χ2/df = 1.846, comparative fit index = 0.921, incremental fit index = 0.923, root mean square approximation error = 059, goodness of fit index = 0.905). The reliability of the instrument was acceptable (Ω > 0.70, α > 0.7, CR >0.60, and intra-class correlation coefficients > 0.70). CONCLUSION: The developed tool is used to measure the control resources of nurses' resilience in caring for COVID-19 patients. It can help recognize the focus areas for developing appropriate interventions.
