Development and psychometric evaluation of the Job Demands in Nursing Scale and Job Resources in Nursing Scale: Results from a national study

AIM: To develop and test the psychometric properties of the Job Resources in Nursing (JRIN) Scale and the Job Demands in Nursing (JDIN) Scale. DESIGN: Cross‐sectional survey. METHODS: A three‐phase process of instrument development and psychometric evaluation was employed: Phase 1: development of a 42‐item JRIN Scale and 60‐item JDIN Scale through extensive literature review, expert consultation and an iterative content evaluation; Phase 2: pilot survey of 89 nurses and use of item discrimination analysis to estimate the internal consistency reliability of each subscale and reduce the length of each scale; Phase 3: Modified scales were tested in a nationwide survey of 3,822 rural/remote nurses, including use of exploratory factor analysis. RESULTS: The 24 items related to job resources favoured a six‐factor structure, accounting for 63% of the variance, Cronbach's alpha 0.88. The 22 items related to job demands favoured a six‐factor structure, accounting for 59% of the variance, Cronbach's alpha 0.84.
