Portuguese Version of the 12-Item Violence Prevention Climate Scale: Test of Psychometric Properties.

BACKGROUND AND PURPOSE: A violence prevention climate is critical for nurses' well-being but also for nursing practice and the quality of care. This study examined the reliability and factor validity of the European Portuguese version of the 12-item Violence Prevention Climate Scale (VPCS).

METHODS

Data came from a sample of 120 nurses providing care in Portugal. Confirmatory factor analysis was used to test the structural theory of the scale.

RESULTS

First and second-order confirmatory factor analysis models showed identical goodness-of-fit suggesting the adequacy of the models to the sample data. Our results also provide evidence of composite reliability, and convergent and discriminant validity.

CONCLUSIONS

Consistent with previous studies, data from this study showed that the Portuguese version of the 12-item VPCS is a reliable and valid scale to evaluate nurses' perceptions of a violence prevention climate.
