Abstract
BACKGROUND
Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder that often negatively impacts behaviour, cognition, and learning. Stimulant medications are the most commonly used treatment for ADHD, with informant reports (e.g., parent questionnaires, surveys) frequently used to evaluate medication impact on behavioural and academic functioning in affected children.
OBJECTIVES
To determine parental perceptions of medication impact on behaviour and learning in a long-acting methylphenidate (LA-MPH) trial of their children with ADHD.
DESIGN/METHODS
A randomized controlled LA-MPH medication trial was conducted with children ages 8–12 with a diagnosis of ADHD. Trial began with one-week of baseline assessment, followed by a randomized three-week standard of care medication trial, and a one-week best dose assessment. Following the conclusion of the study (6 months to 2 years’ range post-treatment), families were asked to participate in a voluntary follow-up phone survey to evaluate parental perceptions on child’s behaviour and learning.
RESULTS
A total of 34/42 (81%) families participated (male to female ratio: 2.1/1). At the time of the follow-up survey, 53% (18/34) and 68% (23/34) of patients were having “difficulty” or “significant difficulty” with their behaviour and learning, respectively. Twenty-three patients (68%) were still on psycho-stimulant medications. Although parents of those 23 children said LA-MPH had in general “significant” or “very significant” impact on their child’s behaviour (87%) and learning (79%), these parents were still reporting challenges with behaviour (52%) and learning (61%) at follow-up. In addition, parents of children not on medication said that their current child’s behaviour and learning was still having the same or more challenging issues (82% and 73% respectively).
CONCLUSION
Overall, parents reported that medication significantly impacted their child’s behaviour and learning; however, long-term medication impact appears less effective. Thus, an ongoing relationship with families and paediatricians is recommended to better understand the impact of medication on behaviour and learning. Evaluating the effects of medication on behaviour and learning may ultimately lead to targeted intervention that help foster long-term treatment efficacy for children with ADHD.
