Background Prevention of musculoskeletal disorders as one of the most common occupational health problems among the working population in both developed and developing countries is an important necessity and priority. The aim of this study was to evaluate the effectiveness of an educational intervention program based on the Health Belief Model (HBM) to increase awareness, perceived sensitivity, perceived severity, perceived benefits, and self-efficacy in adopting neck health-promoting behaviors in school teachers. Methods The present study was a quasi-experimental of the randomized clinical trial that was conducted for 6 months (December 2020 to July 2021). Participants were 146 junior high school teachers were selected from 26 schools through random sampling and divided into two groups of intervention and control. The data collection instrument was the self-design questionnaire and was completed in three points of time (before, immediately, and 3 months after the intervention). The data were analyzed by software version 24 SPSS. Results The results showed that awareness, perceived sensitivity, perceived severity, perceived benefits and barriers, and self-efficacy in adopting neck health-promoting behaviors in the intervention group increased in two points of time (immediately after the intervention and 3 months of follow-up) (P <  0.05). Conclusion Designing and implementing an educational intervention based on HBM could affect in adopting neck health-promoting behaviors among teachers.

Background Neck pain is one of the most common work-related musculoskeletal disorders (WMSDs). It has important social and economic consequences such as reduced productivity due to absenteeism, leave, and early retirement and financial losses due to medical expenses for the workforce especially teachers. This study aims to evaluate whether a model-based social media intervention could change the high-risk behaviors that cause work-related neck pain among teachers. Methods This is a randomized controlled trial that will be done in three steps. The first stage is a qualitative study to obtain the items and areas of the researcher-made questionnaire based on the health belief model (HBM), the second stage is the psychometric evaluation of the questionnaire, and the third stage is designing and implementation of model-based educational intervention in social media context. The study population is teachers who working in junior high school in the 19th district of education minister in Tehran, Iran, which are randomly divided into two groups of intervention and control. The intervention group receives training packages on social media, and the control group does not receive any training. The educational intervention tries to improve the knowledge, attitude, skills, and self-efficacy in adopting neck pain prevention behaviors among teachers. The study will also assess whether the intervention can promote preventive neck pain behavior among teachers. Discussion Work-related neck pain can have a negative impact on teachers’ health. This study is an attempt to investigate the impact of developed interventions in promoting preventive behavior regarding work-related neck pain through social media context.

Background: Neck pain is a common problem among teachers. This study aimed to develop and evaluate an instrument for measuring occupational neck pain preventive behaviors among teachers. Method: In order to develop a neck pain preventive behavior this study was conducted in December 2020 in two phases: qualitative, and quantitative. In qualitative phase a purposeful sample of teachers were interviewed to generate an item pool. Then content validity and face validity were performed to provide a provisional version of the questionnaire. In the next stage, to evaluate the psychometric properties of the questionnaire, a cross sectional study was conducted. In total, 146 teachers participated in this study (with a mean age 36.7; SD 8.92 years). The questionnaire was distributed among a sample of teachers. Exploratory factor analysis was used to obtain the factor structure of the questionnaire. The item-scale correlation matrix was examined to further evaluate the validity of the questionnaire. Internal consistency (Cronbach's alpha) was calculated to assess reliability and intra class correlation coefficient (ICC) to assess stability.Results: Based on analysis of the exploratory factor, 8 factors with 43 substances, that together accounted for 65,25% variances were obtained. Also, the correlation matrix in the case scale to establish the validity of the questionnaire showed satisfactory results. The results of face validity showed that 4 factors were not approved and were removed from the questionnaire. Reliability evaluation with internal consistency method (Cronbach's alpha) showed excellent compatibility (0.87). The intra class correlation reliability assessment showed that the questionnaire has satisfactory stability (ICC) (0.92).Conclusion: This study provides the reliability and validity for the Occupational Pain Neck Preventive Behaviors Questionnaire. The questionnaire evaluates occupational neck pain prevention behaviors among teachers and possibly is useful for using in other settings.
