BACKGROUND: Adults with attention-deficit/hyperactivity disorder (ADHD) may have an increased risk of engaging in suicidal behavior. This study examined this association in the general adult population where there has been little research.
METHODS: Data came from the Adult Psychiatric Morbidity Survey 2007. This was a representative sample of the English adult household population aged ≥16 years (N=7403). The Adult ADHD Self-Report Scale (ASRS) was used to obtain information on ADHD symptoms. The Clinical Interview Schedule Revised (CIS-R) was used to assess six forms of common mental disorder (CMD). Information was also obtained on the lifetime and past 12-month occurrence of suicide ideation and attempts. Logistic regression analysis was used to examine these associations.
RESULTS: After adjusting for comorbid disorders, adults with more ADHD symptoms had significantly higher odds for suicidal behavior. When a single cut-off point was used to classify ADHD (ASRS score ≥14), odds ratios ranged from 1.62 (lifetime suicide attempt) to 2.43 (past 12-month suicide ideation). When ADHD symptoms were categorized by strata (I: a score of 0-9; II: 10-13; III: 14-17; IV: 18-24), compared to adults in stratum I, those in stratum IV had odds ratios ranging from 2.16 (lifetime suicide ideation) to 3.68 (past 12-month suicide attempt).
LIMITATIONS: ADHD and suicide data came from self-reports which may have been affected by socially desirable responding.
CONCLUSIONS: ADHD symptoms were linked to suicidal behavior after controlling for comorbid conditions. Health care professionals should be alerted to the increased suicide risk among adults with ADHD symptoms.
