For GCSE and A level qualifications, there was a difference in the pattern of association across the self harm groups (table 2). In univariable analysis, the odds of not achieving five or more GCSEs or equivalent A*-C grades and not achieving three or more A levels was increased among those with suicidal self harm (odds ratio for GCSE 2.24, 95% confidence interval 1.70 to 2.95 and for A level 1.53, 1.12 to 2.09), but reduced among those with non-suicidal self harm (GCSE 0.83, 0.62 to 1.11 and A level 0.85, 0.67 to 1.08), although findings for non-suicidal self harm did not reach conventional levels of significance. After adjustment for socioeconomic position, symptoms of depression, and IQ, strong evidence remained only for suicidal self harm and GCSE qualifications. Self harm with suicidal intent was also associated with an increased risk of being NEET at age 19 years (adjusted odds ratio 1.96, 95% confidence interval 1.16 to 3.31).
