Acceptance and Commitment Therapy, or “ACT”, is now backed by several hundred Randomized Controlled Trials (RCTs) since the 1980s, with applications ranging from the treatment of mental disorders to the improvement of business performance.
One of the most recent RCTs came from Hong Kong. Originally published as a dissertation, and later in the journal Pediatrics, Yuen Yu Chong and others sought to investigate the extent to which ACT can facilitate parents’ ability to manage their children’s asthma. The team noted that “in the Asia-Pacific region, over half of the Asian children with asthma require emergency care services due to asthma exacerbations per year.”
Though ACT has demonstrated effectiveness with parents of children with a variety of conditions, such as acquired brain injury, cerebral palsy, and anorexia nervosa, this was the first related to asthma.
The team randomly assigned 168 parent-child dyads to one of two groups. The control group received the typical asthma education talk given to parents, plus three weekly telephone followups. The ACT group received the asthma education integrated with a group-based ACT protocol across the same four weeks.
The ACT protocol sought to enhance psychological flexibility on the part of parents. They did so by increasing present moment awareness, promoting acceptance, and encouraging the parents to take action along values-based goals. They noted “throughout the four ACT sessions, six ACT therapeutic processes were applied interchangeably, which were: contacting with the present moment, defusion, acceptance, self-as-context, values and committed action.”
The team found that the children from the ACT group were significantly less likely to visit the emergency room or a private doctor as compared to the control group. Moreover, the children “exhibited fewer days of asthma symptoms during the daytime, fewer nights with disturbed sleep due to asthma symptoms and fewer days of using inhaled bronchodilators.”
The team also reported that parents in the ACT group were less likely to have negative emotional experiences, including worry, anger, and anxiety, which improved quality of life as compared to the control group.
