Abstract

Purpose: The aim of this study was to assess the military performance of men with adolescent attention-deficit/hyperactivity disorder (ADHD) and men with childhood ADHD (in remission during adolescence) as compared with controls without ADHD.

Methods: The study employs the general population-based Northern Finland Birth Cohort 1986 (NFBC1986) together with data received from the Finnish Defence Forces (FDF). A total of 38 men with childhood ADHD and 67 with adolescent ADHD were compared with 160 controls.

Results: The men with adolescent ADHD were more often deemed unfit for military service, had more military health care visits, more often committed at least one offence during service, received poorer evaluations for team leadership skills and indulged in more alcohol consumption and smoking than the controls, while those with childhood ADHD did not differ from the controls in their military fitness, but received poorer evaluations for team leadership skills and smoked more than did the controls.

Conclusions: The conscripts with adolescent ADHD performed worse on many military parameters, but the men with ADHD in remission did not seem to suffer from such negative effects on military performance. The childhood ADHD group in particular was nevertheless somewhat limited in size, which might have led to a Type II error.
