Background Suicidal thoughts and non-suicidal self-harm are common in adolescents and are strongly associated with suicide attempts. We aimed to identify predictors of future suicide attempts in these high-risk groups. Methods Participants were from the Avon Longitudinal Study of Parents and Children, a population-based birth cohort study in the UK. The sample included 456 adolescents who reported suicidal thoughts and 569 who reported non-suicidal self-harm at 16 years of age. Logistic regression analyses were used to explore associations between a wide range of prospectively recorded risk factors and future suicide attempts, assessed at the age of 21 years. Findings 38 (12%) of 310 participants with suicidal thoughts and 46 (12%) of 380 participants who had engaged in non-suicidal self-harm reported having attempted suicide for the first time by the follow-up at 21 years of age. Among participants with suicidal thoughts, the strongest predictors of transition to attempts were non-suicidal self-harm (odds ratio [OR] 2.78, 95% CI 1.35-5.74; p=0.0059), cannabis use (2.61, 1.11-6.14; p=0.029), other illicit drug use (2.47, 1.02-5.96; p=0.045), exposure to self-harm (family 2.03, 0.93-4.44, p=0.076; friend 1.85, 0.93-3.69, p=0.081), and higher levels of the personality type intellect/openness (1.62, 1.06-2.46; p=0.025). Among participants with non-suicidal self-harm at baseline, the strongest predictors were cannabis use (OR 2.14, 95% CI 1.04-4.41; p=0.038), other illicit drug use (2.17, 1.10-4.27; p=0.025), sleep problems (waking in the night 1.91, 0.95-3.84, p=0.069; insufficient sleep 1.97, 1.02-3.81, p=0.043), and lower levels of the personality type extraversion (0.71, 0.49-1.03; p=0.068). Interpretation Most adolescents who think about suicide or engage in non-suicidal self-harm will not make an attempt on their life. Many commonly cited risk factors were not associated with transition to suicide attempt among these high-risk groups. Our findings suggest that asking about substance use, non-suicidal self-harm, sleep, personality traits, and exposure to self-harm could inform risk assessments, and might help clinicians to identify which adolescents are at greatest risk of attempting suicide in the future.
