Problematic alcohol use and suicidal ideation among firefighters: A multi-study investigation of the explanatory roles of perceived burdensomeness and thwarted belongingness

BACKGROUND

Firefighters are at increased risk for both problematic alcohol use and suicidality. Research has found that problematic alcohol use is related to suicidality among this population; however, limited data exist regarding what might account for this association. The present two-study investigation (1) examined the association between suicidality and problematic alcohol use among two large samples of firefighters and (2) tested whether interpersonal theory of suicide constructs-perceived burdensomeness (PB) and thwarted belongingness (TB)-serve as indirect indicators of this relationship.

METHODS

Participants in Study 1 were 944 U.S. firefighters (12.5% female); participants in Study 2 were 241 U.S. women firefighters. Participants completed the Interpersonal Needs Questionnaire, Alcohol Use Disorders Identification Test, and the Depressive Symptom Inventory-Suicidality Subscale (Study 1) or the Self-Injurious Thoughts and Behaviors Interview-Short Form (Study 2). Bias-corrected bootstrap indirect effects path analyses were utilized.

RESULTS

In Study 1, more problematic alcohol use was significantly associated with more severe career suicidal ideation via PB but not TB. In Study 2, problematic alcohol use was associated with career suicidal ideation via both PB and TB. PB seems to account for the relationship between problematic alcohol use and career suicidal ideation among male and female firefighters.

LIMITATIONS

Limitations include use of a cross-sectional design, use of retrospective measures of suicidal ideation, and our findings derived from subsamples of two existing datasets.

CONCLUSIONS

Findings suggest that PB and TB may explain the relationship between problematic alcohol use and suicidal ideation, but that this effect is discrepant based on gender.

Suicidal behaviors and associated factors among university students in six countries in the Association of Southeast Asian Nations (ASEAN)

A large data gap remains on suicidal behaviors among youth in the Association of Southeast Asian Nations (ASEAN) countries, despite the increasing rates of suicide in Asian cultures that may be related to rapid economic changes and the loss of social stability. This study was therefore conducted to explore the prevalence of and factors associated with suicidal ideation and suicide attempts among university students in six ASEAN member states. Data were collected in a cross-sectional survey of 4675 undergraduate university students, mean age 20.6 years (SD=2.7), range of 18-30 years, from Cambodia, Indonesia, Malaysia, Myanmar, Thailand and Vietnam. The overall prevalence of ever suicidal ideation and ever suicide attempt among students in this study was 11.7% and 2.4%, respectively. Different rates of these suicidal behaviors were observed across the countries. In multivariable logistic regression models, suicidal ideation was significantly associated with psychosocial factors including childhood sexual abuse, depressive symptoms, involvement in physical fights, and poor academic performance as well as socio-environmental factors including living with parents or guardians and low involvement in organized religious activity. Suicide attempt was significantly associated with childhood sexual abuse, depressive symptoms, low involvement in organized religious activity and being underweight or overweight. Our findings suggest that individual-level strategies for suicide prevention should be targeted toward students with poor academic performance, mental health problems and a history of adverse childhood experiences. Particular attention should be paid to the role of families that could be a potential stressor in the lives of university students.
