Objective: To compare characteristics between the group who completed suicide and the group who attempted suicide, and to identify factors associated with completed suicide.
Methods: This case-control study was conducted in Nan province, comparing the group who completed suicides and those who attempted suicide. Secondary data from medical records and semi-structured interview notes by psychiatric personnel were used, covering general characteristics, suicide patterns, predisposing factors, precipitating factors, and protective factors. Differences between groups were analyzed using chi-square and Mann-Whitney U tests. Predictors of completed suicide were identified using binary logistic regression.
Results: The sample included 163 subjects, divided into 69 completed suicides and 94 attempts. Compared to the attempt group, the completed suicide group had significantly higher median age and proportions of males, being employed, and use of violent methods such as hanging. Factors that significantly increased the likelihood of completed suicide were male gender (AOR = 4.68, 95% CI = 1.82 - 11.98), presence of physical health problems (AOR = 9.55, 95% CI = 1.55 - 57.75) and lack of self-problem-solving skills (AOR = 3.11, 95% CI = 1.02 - 9.49).
Conclusion: Systematic screening and prevention of completed suicide should be implemented, taking gender differences into account and focusing on high-risk groups facing life crises, especially health and economic issues. Emphasis should also be placed on promotion of self-problem-solving skills to enable adaptive coping with crisis situations.
