Sleep Disturbances, ADHD, and Self-Harm Among Youth

Previous studies have linked ADHD with self-harm, but the processes underlying this association are not fully understood. This research aims to investigate the role of sleep disturbances as a potential pathway between ADHD diagnosis and self-harm behaviors.

The study included 90 youth aged between 11 and 18 years, divided into two groups: a case group of 45 youth diagnosed with ADHD and a control group of 45 youth without ADHD. Both groups completed the Inventory of Statements About Self-Injury to evaluate self-harm behaviors and the Sleep Disturbance Scale for Children to assess sleep disturbances. A path analysis was conducted to examine whether a significant proportion of the association between ADHD and self-harm was shared with sleep disturbances, while controlling for gender, youth education, family income, maternal education, and overall anxiety and depression scores.

An ADHD diagnosis was significantly associated with sleep disturbances (β = .62, p < .001) and self-harm behaviors (β = .35, p = .03). Additionally, sleep disturbances were significantly linked to self-harm (β = .51, p = .002) and played a significant role in the association between ADHD and self-harm (indirect effect β = .32, p = .001).

These findings suggest that sleep disturbances account for a substantial proportion of the shared variance in the association between ADHD and self-harm. While the cross-sectional design limits causal interpretations, these results highlight the importance of addressing sleep issues in clinical care for ADHD to potentially reduce self-harm risks and improve outcomes for at-risk youth.
