Development and validation of an instrument of occupational low back pain prevention behaviours of nurse

Abstract

Aim: To develop and test the psychometric properties of occupational low back pain prevention behaviours questionnaire in nursing personnel. Design: A qualitative and quantitative research design to develop and validate an instrument. Methods: A qualitative study was conducted from May-October 2017 with 20 participants to generate an item pool. Then, content and face validity was carried out. Next, the questionnaire was distributed among a sample of nurses. In all, 150 nurses participated (mean age 34.1; SD 7.66 years) in the study. Exploratory factor analysis used to determine the factor structure of the questionnaire. Item-scale correlation matrix was provided to examine the construct validity. Internal consistency (Cronbach's alpha) was estimated to assess reliability and intraclass correlation coefficient was calculated to examine stability. Results: Six factors with 30 items emerged from the exploratory factor analysis that jointly accounted for 67.9% of the variance observed. Item-scale correlation matrix showed satisfactory results lending support to construct validity of the questionnaire. The Cronbach's alpha coefficient for the whole scale showed excellent internal consistency (0.92), although this was not true for the knowledge subscale. The intraclass correlation coefficient with a 2-week interval also indicated that the questionnaire had satisfactory stability (0.97). Conclusion: This study provides initial support for reliability and validity of the Occupational Low Back Pain Prevention Behaviour Questionnaire. Impact: This study offers an instrument to assess low back pain preventive behaviours among nurses. The instrument is useful for nursing personnel and could be used in hospitals and healthcare settings to implement appropriate interventions.

Psychometric Evaluation of the Chinese Version of Occupational LowBack Pain Prevention Behaviors Questionnaire Among Clinical Nurses: A Validation Study

“…The Cronbach's α coefficient can reflect the homogeneity of items in questionnaire ( 34 ). The results showed that the Cronbach's α coefficient of the Chinese version of the questionnaire was 0.885, and the Cronbach's α coefficient of each dimension ranged from 0.903 to 0.924, which is slightly higher than the result of the original questionnaire ( 24 ), indicating that the items of the Chinese version of the questionnaire has higher internal consistency. Similarly, the split-half reliability coefficient was 0.663, which once again confirms the above conclusion.…”

“…The results showed that I-CVI ranged from 0.857 to 1.000, and Q-CVI was 0.952, which is higher than the reference value of content validity of 0.9 and 0.8, respectively ( 36 ). Furthermore, the EFA results showed that the six common factors of the Chinese version of the questionnaire explained 73.623% of the total variance, and the factor loading of each item in the questionnaire was >0.4, and the factor attribution of each item was consistent with the original version ( 24 ), which indicating that the Chinese version of the questionnaire has suitable construct validity. Meanwhile, in CFA, the fitting index of the Chinese version of the questionnaire was within the acceptable range and stronger than that of the original version ( 24 ).…”

Meanwhile, in CFA, the fitting index of the Chinese version of the questionnaire was within the acceptable range and stronger than that of the original version ( 24 ). In conclusion, we consider that the Chinese version of occupational low back pain prevention behaviors questionnaire has suitable content validity and structural validity among clinical nurses.…”

“…The level of occupational low back pain prevention behaviors was measured by the occupational low back pain prevention behaviors questionnaire developed by Kazemi et al ( 24 ). The questionnaire consisted of six dimensions with 30 items.…”

“…However, these tools do not examine the effective factors that might help to promote health behaviors. Therefore, from the salient features of health promotion and arising out of the PRECEDE-PROCEED model, the occupational low back pain prevention behaviors questionnaire was developed ( 24 ). The prevention of occupational low back pain is a repeated process of assessing prevention knowledge and the practice of prevention behavior to meet the professional's internal and external needs in work ( 25 ).…”
