Predicting the work ability of security guards at a university in Nakhon Si Thammarat province, Thailand.

Objectives. The number of security guards in universities has increased significantly. This study aimed to predict work ability of university security guards. Methods. A cross-sectional study of 97 university security guards in Thailand was performed. Data were collected through interviews using a questionnaire covering social demographics, behavioral health and work ability. The data were analyzed using χ2 tests and logistic regression models. Results. The average work ability index (WAI) score was 38.1 ± 3.8, with 65.0% of participants scoring 'good'. Social support significantly influenced the WAI (p = 0.004). Those with insufficient support were 4.3 times more likely to show poor work ability. Mental health also impacted the WAI (p = 0.006); those with poor mental health were 4.7 times at risk. Additionally, work experience affected the WAI (p = 0.039). Those with ≥5 years of experience showed reduced work ability compared to their less-experienced counterparts (adjusted odds ratio 0.4; 95% confidence interval [0.20, 0.96]). Conclusions. Supervisors should provide social support and offer rewards and commendations to enhance employees' abilities, health behaviors and management of underlying diseases. Additionally, organizations should prioritize health and safety in the workplace to ensure their employees are healthier and perform their tasks more effectively.

Effects of safety interventions toward workers' behaviors using the theory of planned behavior in the rubber wood processing industry.

Objectives. Rubberwood manufacturing has a wide range of occupational safety hazards. Workers' safety behaviors are substandard. This quasi-experimental study aimed to determine the factors affecting safety behaviors using the theory of planned behavior (TPB) and compare the effects of safety intervention programs on workers' behaviors. Methods. The sample comprised workers from a rubberwood processing factory. Exploratory and confirmatory factor analyses were performed to validate the TPB constructs. The constructs were also analyzed before and after the interventions using structural equation modeling to confirm the observed variables. The interventions included conducting job safety analysis, establishing safety standard operation procedures and launching a behavioral promotion campaign. A t test was used to compare the constructs' intervention effects. Results. The structural equation model adequately fit the data and confirmed that the constructs were aligned with the TPB. Most path coefficients were statistically significant after the interventions were implemented. 'Attitude' and 'perceived behavioral control' directly and significantly affected 'intention'. 'Intention' was an essential mediator to 'behaviors'. The improvement in workers' behaviors was evident. Conclusions. According to the TPB, safety program interventions helped enhance workers' behaviors. Hence, based on participatory approaches, sustainable safety interventions should be maintained for all levels of personnel in the organization.

Developing the Vulnerability Factor Structure Affecting Injuries and Health Problems Among Migrant Seafood Processing Industry Workers.

Background: The vulnerability of international migrant workers is on the rise, affecting the frequency of occupational accidents at workplaces worldwide. If migrant workers are managed in the same way as native workers, the consequences on safety assurance and risk management will be significant. This study aimed to develop the vulnerability factor model for migrant workers in seafood processing industries because of significant risk-laden labor of Thailand, which could be a solution to control the risk effectively. Methods: A total of 569 migrant workers were surveyed (432 Burmese and 137 Cambodian), beginning with 40 initial vulnerability factors identified in the questionnaire established from experts. The data were analyzed through descriptive analysis; exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were used to ascertain the model. Results: The result of content validity >0.67 and the Cronbach's alpha of 0.957 specified the high reliability of 40 factors. The EFA indicated a total variance of 65.49%. The final CFA validated the model and had an empirical fitting; chi-square = 85.34, Adjust Goodness-of-Fit Index = 0.96, and root mean square error of approximation = 0.016. The structure concluded with three dimensions and 18 factors. Dimension 1 of the structure, "multicultural safety operation," contained 12 factors; Dimension 2, "well-being," contained four factors; and Dimension 3, "communication technology," contained two factors. Conclusion: The vulnerability factor structure developed in this study included three dimensions and 18 factors that were significantly empirical. The knowledge enhanced safety management in the context of vulnerability factor structure for migrant workers at the workplace.
