Effect of Occupational Health and Safety Training for Chinese Construction Workers Based on the CHAID Decision Tree

Abstract

Background: Occupational health and safety (OHS) training is an important way to prevent construction safety risks. However, the effectiveness of OHS training in China is questionable. In this study, the CHAID (chi-squared automatic interaction detection) decision tree, chi-square analysis, and correlation analysis were used to explore the main, secondary, weak, unrelated, and expectation factors affecting the effectiveness of training. It is the first to put forward the “five-factor method” of training effectiveness. It is found that training effectiveness is positively correlated with job responsibilities, OHS training, and job satisfaction. It is also significantly related to job certificate, training time, training method, and working time. However, the effectiveness of training has nothing to do with personal age, marital status, educational level, job type, and whether or not they have experienced industrial accidents. And the workers on site expect the enterprise to provide security and opportunities such as physical safety, training and learning, and future career development. The results show that OHS system training should be strengthened in the construction industry, and classified training should be carried out according to post responsibility, training methods, job satisfaction, and working hours.

Effect of Occupational Health and Safety on Employee Performance in the Ghanaian Construction Sector

“…Thus, the findings of that health and safety training for construction workers is essential for their safety at the construction site needed for safety, hazard management and emergency procedures for safety management is upheld by this study. Furthermore, Taylor et al 22 and Cao et al 8 found that if general health and safety policies are to be incorporated into specific job practices and skill levels are to be raised to an acceptable standard, training is required, further corroborated by this findings study.…”

“…Additionally, due to competing political, social and economic interests, OHS issues are mostly neglected in most African countries. 7 , 8 The effect of poor or lack of occupational health and safety policies in organisations in Africa is mostly deaths, permanent disabilities, severe injuries and absenteeism. One of Africa’s key sectors or industries closely associated with health and safety issues is the construction industry.…”

Clinical prediction rule for bacterial arthritis: Chi-squared automatic interaction detector decision tree analysis model

“…The categories of each independent variable were merged if they were not significantly different from the dependent variable and the cutoff values are established automatically by the chisquare test results. [27][28][29][30][31] Furthermore, we add and express it in other words by the explanation of CHAID model from other precedence articles, the CHAID algorithm is a nonparametric procedure and, therefore, it required no assumptions to be made of the underlying data. Also, CHAID treats the entire system and user-missing values for each independent variable as a single category.…”

Occupational Health and Safety Scope Significance in Achieving Sustainability

“…Methodologically wise, following a critical review of existing relevant studies [78,[97][98][99][100][101], an online questionnaire was developed and administered using Google Forms as the main tool, an approach in accordance with the practice used widely [102][103][104][105][106]. The questionnaire was developed adapting the 'Safety Culture Questionarrie', used by the University of Aegean in a relevant study [100], as well as previous work on factors affecting the level of awareness regarding OSH [66,[107][108][109][110]. Ultimately, a 19-item questionnaire was developed.…”
