Efficacy of behavioural parent training on attachment security in children with attention deficit hyperactivity disorder: a randomised controlled trial

Abstract

Abstract Background Behavioural parent training (BPT) is a psychosocial intervention designed for children with attention deficit hyperactivity disorder (ADHD). BPT programs teach parents to use effective commands or rules whilst encouraging them to pay careful attention to their child’s appropriate behaviour. In this study, we will investigate the efficacy of BPT on parental stress, mothers’ sense of emotional closeness to their children, and children’s attachment security to their mothers. We will also examine the effects of BPT on children’s internalising and externalising symptoms, ADHD symptoms, and sensitivity to rewards and punishments compared to usual care alone. The use of bias-prone assessment tools limits the ability of previous studies to assess effectiveness. Therefore, in this study, the child’s attachment security will be assessed in a structured interview conducted by assessors blinded to group allocation, and brain changes will be assessed using magnetic resonance imaging. Methods This randomised controlled clinical trial will aim to compare the efficacy of BPT to routine clinical care for 60 children with ADHD. Participants will be randomised, with stratification by medication status for ADHD (medicated or non-medicated). The BPT intervention group will receive parent training weekly for 10 weeks in a group of six or less. The primary outcome measure will be changes in parental stress. Furthermore, the key secondary outcome measure will be the child’s attachment security, which will be assessed in an interview conducted by assessors blinded to group allocation. We will also evaluate changes in neural connectivity in both children and mothers using magnetic resonance imaging. Other secondary outcomes will include child behavioural problems, ADHD symptoms, emotional regulation, child sensitivity to rewards and punishments, parental behaviour, and the child and parent’s social support network following the completion of 10 sessions. Discussion This study represents the first randomised controlled trial exploring the efficacy of BPT on child attachment security and mothers’ sense of emotional closeness to their children. It aims to provide robust evidence to assist parents of children with ADHD in making appropriate treatment decisions. Trial registration UMIN000038693. Registered on November 9, 2019.
