Abstract
BACKGROUND: Nonsuicidal self-harm includes cutting, scratching, burning and minor overdosing. There have been few studies that have examined the rate of self-harm and mental-health correlates among community-based youth. We performed a population-based study to determine the prevalence of nonsuicidal self-harm, its mental-health correlates and help-seeking behaviour. METHODS: We used data from the Victoria Healthy Youth Survey, a population-based longitudinal survey of youth aged 14-21 in Victoria, British Columbia. The survey included questions about the history, method, frequency, age of onset and help-seeking for nonsuicidal self-harm. Youth were interviewed between February and June 2005. Univariable group differences were analyzed using students t test for continuous data and chi2 for binary or categorical data. Multivariate analyses were conducted by use of multivariate analysis of variance and logistic regression. RESULTS: Ninety-six of 568 (16.9%) youth indicated that they had ever harmed themselves. Self-injuries such as cutting, scratching and self-hitting were the most common forms of nonsuicidal self-harm (83.2%). The mean age of onset was 15.2 years. Of those who reported nonsuicidal self-harm, 56% had sought help for this behaviour. Participants who reported 5 or more symptoms (out of 6) in a given symptom category were more likely than those who reported less than 5 symptoms to report nonsuicidal self-harm for the following categories: depressive mood (odds ratio [OR] 2.18, confidence interval [CI] 1.28-3.7) and problems with regulation of attention, impulsivity and activity (OR 2.24, CI 1.33-3.76). INTERPRETATION: We found a high lifetime prevalence of nonsuicidal self-harm. Many mental-health symptoms were associated with this behaviour, particularly those with depressive mood and attention-related problems. Just over half of youth reported seeking help for nonsuicidal self-harm. Clinicians who encounter youth should be vigilant to assess for this behaviour in youth who present with mental health issues.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
