OBJECTIVE. In this study, we examined the effectiveness of using weighted vests for improving attention, impulse control, and on-task behavior in children with attention deficit hyperactivity disorder (ADHD).
METHOD. In a randomized, two-period crossover design, 110 children with ADHD were measured using the Conners’ Continuous Performance Test–II (CPT–II) task.
RESULTS. 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 behaviors, including off task, out of seat, and fidgets. No significant improvements in impulse control and automatic vocalizations were found.
CONCLUSION. Although wearing a weighted vest is not a cure-all strategy, our findings support the use of the weighted vest to remedy attentional and on-task behavioral problems of children with ADHD.
Weighted vests could be provided as a useful modality to assist with improving the attentional and behavioral performance of children with ADHD.
Wearing weighted vests truly improves three aspects of attentional performance (inattention, speed of processing and responding, and consistency of executive management) of children with ADHD, although this method is not a cure-all strategy for their attentional deficits.
Wearing weighted vests truly improves three aspects of behavioral performance (off task, out of seat, and fidgets) of children with ADHD, although this method is not a cure-all strategy for their behavioral deficits.
Practitioners who adopt weighted vests to provide deep-touch pressure should apply the technique cautiously, especially if wearing protocols different from those in this study are used.
