title: Psychometric Properties of the Survey of Workplace Intimidation Instrument.
abstract: OBJECTIVE
  The purpose of this study was to assess the psychometric properties of the Survey of Workplace Intimidation (SWI), including content and construct validity, factor structure, and internal consistency.
  
  
  METHODS
  A cross-sectional, descriptive study design was used for this study. The final sample consisted of 237 labor and delivery nurses who completed the SWI and the Practice Environment Scale of the Nursing Work Index (PES-NWI). Cronbach's alpha for the SWI was .930.
  
  
  RESULTS
  Content validity was obtained and the scale content validity index (S-CVI) was .943. Convergent validity was calculated by comparing the SWI with the PES-NWI, and the result was .408 (p = .01). A factor analysis explained 61% of the variance and resulted in two factors: prescriber behaviors and nurses' responses to prescribers' behaviors.
  
  
  CONCLUSIONS
  The SWI demonstrated acceptable reliability and validity.
