The study examines the effectiveness of using weighted vests for improving attention, impulse control, and on-task behaviour in children with attention deficit hyperactivity disorder (ADHD).
In a randomized, two-period crossover design, 110 children with ADHD were measured using the Conners’ Continuous Performance Test–II (CPT–II) task. The results showed that in the weighted vest condition, the participants did show significant improvement in all three attentional variables of the CPT–II task, including inattention; speed of processing and responding; consistency of executive management; and three of four on-task behaviours, including off task, out of seat, and fidgets. No significant improvements in impulse control and automatic vocalizations were found.
Although wearing a weighted vest is not a cure-all strategy, the findings support the use of the weighted vest to remedy attentional and on-task behavioural problems of children with ADHD.
