Development and Psychometric Evaluation of the Behavioral Risk Assessment Scale for Work-Related Musculoskeletal Risk in Nurses (BRASM-N).

Existing assessment tools often focus on isolated risk domains, limiting their applicability in comprehensive ergonomic risk evaluation.

Content validation produced a 22-item scale with acceptable to excellent item relevance (I-CVI = 0.78-1.0).

In 382 nurses, exploratory and confirmatory factor analyses supported a stable four-factor structure with good model fit (CFI = 0.94, TLI = 0.93, RMSEA = 0.049).

Test-retest reliability was strong (ICC = 0.76-0.91).
