An interventional study of ACT intervention and Usual/standard control in Psychological Outcomes and Quality of Life, sponsored by The Hong Kong Polytechnic University. Not yet recruiting. Open to participants aged 18 Years and older, including healthy volunteers. Per ClinicalTrials.gov, last updated 2026-09-11.
Sponsored by The Hong Kong Polytechnic University · Not applicable, Interventional, and Supportive care
The goal of this randomized controlled trial is to evaluate whether a group-based acceptance and commitment therapy (ACT) can improve the psychological outcomes and quality of life (QOL) of children with cerebral palsy. The main questions it aims to answer are:
Researchers will compare a group-based ACT to usual/standard care to determine whether ACT improves participants' psychological outcomes and QOL.

Exclusion Criteria:
Behavioral: ACT intervention
Other: Usual/standard control
Participants in the intervention group will receive an ACT that consists of eight sessions. Th introductions include an introduction, cognitive defusion, acceptance, being present, values, committed action, and noticing self/self-as context, and a summary session. An ACT-trained researcher will deliver weekly, face-to-face, group-based sessions, each lasting approximately 90 minutes, though durations may vary to accommodate group variations. Each group will consist of five to seven participants. The interventions will be delivered via various strategies, including psychoeducation, discussion, mindfulness exercises, and metaphors supplemented with with home practices. A research assistant will conduct a weekly phone call assessment to address any study-related concerns and provide reminders for the next appointment or assessment day.
Participants in the control group will receive the usual or standard care provided by the respective center. To enhance participant retention in the study, a weekly phone call will be conducted by a research assistant, during which participants will be asked whether they have any concerns about the study and reminded of the next appointment or assessment day.
Level of psychological flexibility
The psychological flexibility will be assessed using the 7-item Acceptance and Action Questionnaire-II (AAQ-II). Each item in the AAQ-II is scored on a scale of seven from 1(never true) to 7(always true). The total score is obtained by summing the scores of all items, and the higher the total score indicates greater psychological inflexibility.
Time frame: Baseline (before intervention), post-intervention (at 8 weeks), and follow-up (6 weeks post-intervention).
Level of psychological distress
The psychological distress outcomes including, anxiety, depression, and stress will be assessed using the self-report 21-item anxiety, depression, and stress scale (DASS-21). Each of the subscales comprises 7 items and is scored on a four-point Likert scale ranging from 0(didn't apply at all to me) to 3(applied to me very much or most of the time), and the score is calculated by summing up the items in each subscale, and the final core is obtained by multiplying the core by two to make it comparable with the full scale (DASS-42). The higher the core indicates high distress symptoms.
Time frame: Baseline (before intervention), post-intervention (at 8 weeks), and follow-up (6 weeks post-intervention).
Level of quality of life
The quality of life will be evaluated by using the World Health Organization Quality of Life-BREF (WHOQOL-BREF). It comprises four domains: physical health, psychological, social relationships, and environment. Each item is scored on a five-point scale from 1 to 5, with varying response options across the domains, and some items need to be reversely scored. There are two items examined separately and will not be included in the score calculation. Domain scores are calculated by summing up the mean of all items in each domain and multiplying by four, and then the total score is transformed to a 0-100 scale to make the domains comparable. A higher the score indicates a higher QOL.
Time frame: Baseline (before intervention), post-intervention (at 8 weeks), and follow-up (6 weeks post-intervention).

Start is estimated for Oct 2026; primary completion for Jan 2027, 3 months later.
Of 3,841 non-industry interventional studies with no phase under Anxiety Disorders, half reached primary completion within 12 months of starting (the median), counting those still running; a quarter within 5 and three quarters within 28. This study's planned 3 months is below that.
Counting every sponsor, half of 3,943 studies reached it within 12 months; a quarter within 5 and three quarters within 28.
