Mood and Proneness to Boredom Are Associated with Poorer Continuous Performance Test Results, Which May Improve with Methylphenidate Treatment, in Attention-Deficit/Hyperactivity Disorder

Objectives: This study aimed to evaluate the relationship between baseline test of variables of attention (TOVA) performance, attention-deficit/hyperactivity disorder (ADHD) symptom severity, mood symptoms, proneness to boredom in children with ADHD, and to assess the responses of the various scales to methylphenidate treatment. Methods: Thirty-three children and adolescents with ADHD, aged 7-18 years, were assessed at baseline with TOVA and treated for 3 months thereafter with methylphenidate. The ADHD Rating Scale (ADHD-RS), Short Boredom Proneness Scale (SBPS), Children's Depression Inventory (CDI) scale, and CDI-academic and social subscale (CDI-AS) were administered to all participants at baseline and after 3 months of methylphenidate (MPH) treatment. Results: The baseline TOVA reaction time (RT) and RT variability parameters correlated with baseline SBPS and CDI-AS scores as well as with baseline total CDI scores. Significant improvements were found in ADHD-RS, SBPS, and CDI-AS scores after MPH treatment. The alteration in ADHD-RS correlated with parallel changes in SBPS and CDI-AS scores. Conclusions: Mood and proneness to boredom correlate with poor attention-span in children with ADHD. Improvement in ADHD levels after MPH treatment correlates with a parallel decrease in mood symptoms related to academic achievement and social functioning.

Automated summary

This study found that mood and proneness to boredom are related to poor attention-span in children with ADHD, and improvement in ADHD levels after methylphenidate treatment correlates with a parallel decrease in mood symptoms related to academic achievement and social functioning.
