Abstract
Objective
Non‐suicidal self‐injury (NSSI) comprising thoughts and behaviors is common and often co‐occurring with suicidal behavior like ideation, plan and attempt. As limited data is available for adolescents and young adults, this study aims to present prevalence estimates for lifetime NSSI, its co‐occurrence with suicidal behavior, conditional probabilities and their association with socio‐demographic characteristics, severity characteristics of suicidal behavior, and health service utilization.
Methods
The epidemiological Behavior and Mind Health (BeMIND) study assessed in 2015/16 a random‐community sample of N = 1180 aged 14‐21 years from Dresden, Germany, regarding lifetime NSSI via self‐administered questionnaire and suicidal behaviors via standardized interview.
Results
Any lifetime NSSI was reported by 19.3% (thoughts: 18.0%, behaviors: 13.6%) of the sample with higher prevalence in females (OR = 2.7, 95% CI 1.9‐3.8, P < .001). Lifetime prevalence of co‐occurring NSSI and suicidal behavior was 7.7%. Females had a 3.3 to 8.8‐fold odds of co‐occurrence than males. Among those with any NSSI, 39.6% endorsed suicidal behavior, and 66.3% of those with any suicidal behavior reported NSSI. 42.3% of those with any NSSI reported to have used mental health care services at any time during their life with higher rates in those with co‐occurring suicidal behavior (62.3%).
Conclusion
NSSI and co‐occurring suicidal behavior is common in adolescents and young adults – especially females. The limited utilization of mental health care services underpins the need for improving recognition of NSSI and suicidal behavior as well as the accessibility of mental health care services during adolescence and emerging adulthood.
