Effectiveness of Self-Compassion Intervention on Enhancing Self-Compassion and Psychological Well-Being of Children With Attention Deficit/Hyperactivity Disorder

The study aims to investigate the underlying mechanism between Attention Deficit/Hyperactivity Disorder traits (AD/HD traits) and psychological well-being through studying the role of perceived criticism, rejection sensitivity, self-compassion and growth mindset. It also aims to explore the effectiveness of self-compassion intervention on enhancing self-compassion and psychological well-being of children with AD/HD in Hong Kong. The study will contribute to the current understanding of the supportive measures for children with AD/HD, and hopefully help to mobilize more resources to preserve children with AD/HD's mental health. The intervention program includes the following components: Participants will be randomly assigned to the self-compassion intervention group or the waitlist control group. The intervention group consists of two parts: children training session and parent group sessions. All children participants will complete a total of 6 training sessions, and each session will last around 90 minutes. Parents of the children participants will also complete a total of 3 group sessions, and each session will last around 90 minutes. To investigate the intervention effectiveness, children will be asked to complete a questionnaire assessing their levels of self-compassion, emotional regulation, as well as psychological well-being in terms of life satisfaction, positive and negative affect. Parents and teachers of participants will also be asked to complete a questionnaire covering children's emotional regulation, positive and negative affect. Questionnaire data collection will be conducted prior to the intervention (i.e., Time 1), immediately after the 6-session student and 3-session parent sessions (i.e., Time 2), and 2 months after the intervention (i.e., Time 3, a 2-month follow up). It takes approximately 20-30 minutes for children and parents to complete their questionnaires. Study Objectives: 1.
