Predicting the Frequency of Adolescent Self Injury
Background/Purpose: A substantial proportion of youth lacking in support or adaptive coping skills may be at risk for trying self-injury. The purpose of this study was to identify predictors of the frequency of self-injury among 1748 sixth and eighth graders using the middle school Youth Risk Behavior Survey (YRBS).
Methods: Secondary data analysis using multilevel modeling using HLM.6 was used to identify statistically significant predictors of the frequency of self-injury.
Results/Outcomes: Among youth who self-reported having ever tried self-injury (N=495; 28%), 35% had harmed themselves once and 35% had harmed themselves more than once during the past month. Those who self-injured once (compared to never) were more likely to demonstrate abnormal eating behaviors (OR = 3.69, 95% CI 1.70, 8.05), exposure to peer self-injury (OR = 1.72, 95% CI = 1.21, 2.44), and higher level of suicidal tendencies (OR = 1.63, 95% CI = 1.33, 2.01). Those who had self-injured more than once (compared to never) were more likely to demonstrate higher levels of suicidal tendencies (OR = 2.84, 95% CI 2.27, 3.55), inhalant use (OR = 2.52, 95% CI = 1.47, 4.31), and lower levels of belief in their possibilities (OR = 0.61, 95% CI = 0.42, 0.88). Finally, those who self-injured more than once (compared to once) demonstrated higher levels of suicidal tendencies (OR = 1.74, 95% CI 1.37, 2.21).
Conclusions: Overall, results suggested the presence of multiple predictors of the frequency of self-injury, which leads us to greater understanding of those factors to target for prevention.
