validation of questionnaire to assess occupational health risks and perceived health problems among nurses

Background: occupational health is crucial in healthcare, where nurses encounter diverse hazards that impact their well-being and safety. this study aimed to construct and validate a comprehensive questionnaire to assess occupational health risks and perceived health problems among nurses.materials and methods: this exploratory study involved constructing and validating a questionnaire in four phases: item generation, determination of essentiality using the content validity ratio (cvr), subsequent validation for content, principal component analysis, and assessment of internal consistency. the occupational health risks domain comprises 33 items across two major domains (biological and non-biological), while the perceived health problem domain includes 15 items addressing health issues relevant to the nursing profession.results: content validity was achieved through expert review, with an item-level content validity index (i-cvi) of 1 for all items and a scale-level content validity index (s-cvi) of 0.93, exceeding the threshold for significance. the kappa statistic of 1 demonstrates perfect inter-rater agreement. the kmo was 0.8, with a p-value of <0.05, indicating suitability, as similar factors or components were extracted with the constructed questionnaire. on the other hand, it exhibits good internal consistency, with a cronbach’s alpha value ranging from 0.76 to 0.83.conclusions: thus, the constructed questionnaire was validated, and the tool proved to be reliable and effective for assessing the occupational health risks and health perceptions of nurses. it can provide a foundation for assessments, effective interventions, and policy enhancements within healthcare organizations.
