Psychological Outcomes

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: * Does a group-based ACT improve the psychological flexibility of the participants? * Does a group-based ACT improve the psychological distress, including depression, anxiety, and stress, of the participants? * Does a group-based ACT improve the QOL of the participants? Researchers will compare a group-based ACT to usual/standard care to determine whether ACT improves participants' psychological outcomes and QOL. Participants will: * Receive eight weekly, face-to-face, group-based ACT sessions, each lasting approximately 90 minutes. * Receive home-based practices following each session. * Receive a weekly phone call assessment to address any study-related concerns and provide reminders for the next appointment or assessment day. * Complete the questionnaires at three times: baseline (before intervention), post-intervention (at 8 weeks), and follow-up (6 weeks post-intervention).
