Development and psychometric evaluation of a tool to assess oncology nurses' occupational health needs

Oncology nurses are confronted with various occupational hazards; consequently, it is of great importance to identify and measure their occupational health needs. Due to the fact that standard tools are not available to assess these needs, this study was conducted to develop a tool for assessing oncology nurses' occupational health needs.

This study consisted of two phases from 2020 to 2021. The first phase was item generation and tool design. The initial development of the item pool was based on the result of the qualitative study and literature search. The second phase was item reduction and psychometric evaluation of the formulated tool including, face, content, and construct validity and reliability. Construct validity was assessed using exploratory factor analysis and convergent validity with the participation of 300 oncology nurses. The reliability of the tool was assessed using internal consistency (Cronbach's alpha) and test-retest (intra-cluster correlation coefficient).

The mean content validity index (CVI) of the tool was 0.95. The results of exploratory factor analysis showed that this tool consisted of 69 items and four factors, explaining 65.88% of the variance. The results of the convergent validity assessment showed a significant positive correlation between the mean scores of occupational health needs and occupational stress (P < 0.0001 and r = 0.40). Cronbach's alpha coefficient (0.98) and tool stability (0.98) confirmed the appropriate reliability of the tool.

The developed tool is recommended as a valid and reliable tool for assessing oncology nurses' occupational health needs that can be used both in practice and in future studies.
