Objective: To understand the suicidal ideation among migrant construction male workers in Pudong New Area, Shanghai, and analyze the influence factors based on social cognitive theory. Methods: Surveys were carried out among 1 850 migrant construction male workers from 3 randomly chosen construction sites using cluster random sampling. Univariate and multivariate Logistic regressions analysis were used to explore the association between suicidal ideation and its related factors such as negative psychology, negative cognition and high-risk behavior. Results: Among the total 1 580 respondents completed the survey, 126 (8.0%) reported having suicidal ideation. In the univariate Logistic regression analysis, drug abuse, alcohol abuse, depression, generalized anxiety and loneliness were risk factors for suicidal ideation, while perceived social support was a protective factor. Five of the six variables, alcohol abuse (ORm=2.15, 95%CI 1.42-3.24), depression (ORm=2.47, 95%CI 1.17-5.21), generalized anxiety (ORm=2.24, 95%CI 1.50- 3.35), loneliness (ORm=2.09, 95%CI 1.28-3.40) and perceived social support (ORm=1.84, 95%CI 1.20-2.83) were selected by the multivariate Logistic regression analysis. Conclusion: Suicidal ideation among migrant construction male workers in Pudong New Area, Shanghai occurs under the influence of negative psychology, negative cognition and high-risk behavior. For the crowds, family and society should be actively promoted and mental health interventions should be strengthened, which could effectively prevent suicide ideation. © 2018, Editorial Department of Journal of Shanghai Second Medical University.
