Measurement Properties of the Polish Nurse-Nurse Collaboration Scale: A Psychometric Study.

Background and Purpose: Reliable measurement of nurse-nurse collaboration requires psychometrically sound instruments with stable factor structures across cultural contexts. Previous cross-cultural studies of the Nurse-Nurse Collaboration Scale (NNCS) suggest variability in its dimensional structure. This study aimed to evaluate the psychometric properties of the Polish version of the NNCS (NNCS-Pl).

Methods

A cross-sectional study was conducted among 312 professionally active nurses in Poland. The NNCS was translated and culturally adapted following established guidelines. Construct validity was examined using confirmatory factor analysis (CFA) and exploratory factor analysis (EFA). Convergent and discriminant validity and internal consistency were also assessed.

Results

CFA indicated acceptable overall model fit but limited discriminant validity. EFA yielded a refined five-factor, 26-item structure with satisfactory reliability (α = .73-0.84; ω = .72-.85).

Conclusions

The NNCS-Pl demonstrates satisfactory reliability and construct validity and is suitable for research on nurse-nurse collaboration in cross-cultural contexts.
