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

摘要

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.
