Psychometric properties of the Persian version of Pressure Ulcer Management Self-Efficacy Scale for nurses.

BACKGROUND

Pressure ulcers remain a major clinical challenge, and nurses' self-efficacy is essential for their prevention and management. The Pressure Ulcer Management Self-Efficacy Scale (PUM-SES) for nurses was developed to assess this competency.

AIM: This study aimed to translate, culturally adapt and validate the Persian version of the PUM-SES (PUM-SES-P) among Iranian nurses.

METHODS

This three-phase study began with forward and back translation. In phase two, face and content validity were evaluated by 10 nurses and 15 experts, respectively, and construct validity and reliability were assessed among 200 and 30 nurses. In phase three, criterion-related and convergent validity were evaluated among 100 nurses.

RESULTS

Content validity indices were favourable (content validity index = 0.97, content validity ratio = 0.90), and factor analysis supported a four-factor structure. The scale showed high internal consistency (α = 0.91) and acceptable test-retest reliability (r = 0.89). Correlations with General Self-Efficacy Scale (r = 0.88) and Attitude towards Pressure Ulcer Prevention instrument (r = 0.77, p < 0.001) supported validity.

CONCLUSIONS

The PUM-SES-P appears to be a valid, reliable instrument for assessing pressure ulcer self-efficacy among Iranian nurses in this sample, offering a potentially useful resource for nurse educators and unit managers. Further validation in larger, more diverse samples is recommended before broader clinical application.
