Attention deficit/ hyperactivity disorder (ADHD) is commonly prevalent among children worldwide. More than 40,000 children are estimated to suffer from ADHD, with the average prevalence rate reaching approximately 6.4% (Liu et al., 2018;Sayal et al., 2017). ADHD is a mental disorder marked by inattention, hyperactivity and impulsivity; it interferes with cognitive and social development of children. These symptoms commonly manifest in children below 12 years of aged (National Institution of Mental Health, 2020). Children with ADHD have higher activity levels, combined with the inability to control their temper as compared with age-matched peers (American Psychiatric Association, 2013). Children with ADHD face obstacles in social relationships and in academics, which parents perceive as a burden (Aili et al., 2015;Lan et al., 2015). In Hong Kong, parents are the main caregivers of children with ADHD (Lan et al., 2015).
