The Association between Hyperactivity and Suicidal Behavior and Attempts among Children Referred from Emergency Departments

The global prevalence of suicidal behaviors in children is rising, with attention-deficit hyperactivity disorder (ADHD) proposed as a contributing factor. This study examines the association between ADHD facets (hyperactivity and inattention) and suicidal behavior and attempts in children. Additionally, it seeks to compare self-reported ADHD symptoms and suicide-related incidents with parental reports. A cohort of 71 children referred from emergency departments due to suicidal thoughts and behaviors completed self- and parental report questionnaires. The results revealed that elevated hyperactivity scores, surpassing the ADHD diagnosis threshold, were significantly associated with increased rates of suicidal behavior. Hyperactivity demonstrated a stronger association with lifetime suicide attempts compared to inattention. Moreover, children’s self-reported ADHD symptoms exhibited a stronger correlation with suicide attempts than parental reports. This study highlights the critical role of hyperactivity in understanding suicidal behaviors among children with ADHD. It underscores the importance of considering hyperactivity-related symptoms in assessment and treatment approaches for suicidal behavior in this population.
