Abstract

There is no valid scale to measure health related procrastination, especially in nurses. This study was conducted to design and assess the psychometric properties of the health-related procrastination scale in nurses. This exploratory mixed method study was conducted between April 2017 and May 2019. The design and psychometric assessment of the nurses' health-related procrastination scale (NHRPS) was carried out through quantitative and qualitative phases. In the qualitative phase, nurses were interviewed and a review of literature was carried out to generate the items. In the quantitative phase, the scale validity was evaluated using the face, content and construct validity and its reliability was evaluated through the Cronbach's alpha, McDonald's omega, intra-class correlation coefficient, standard error of measurement, minimal detectable changes. The results of the exploratory factor analysis showed that, with 29 items and five factors, the NHRPS explains 54.81% of the variance in NHRPS. The results of confirmatory factor analysis also confirmed the final fit of model with five factors (RAMSEA: 0.08, CMIN/DF: 2.42, NFI: 0.92, PNFI: 0.83, CFI: 0.95, IFI: 0.95, RFI: 0.91, SRMR: 0.074). The Cronbach's alpha of the scale was 0.947, its intra-class correlation coefficient was 0.944, the Half-fold consistency coefficient was 0.970 and Omega internal consistency coefficient was 0.96. The NHRPS has good psychometric properties. This scale is suitable for research purposes, especially to plan for nurses' health promotion. © 2023 The Authors
