Description of intervention(s) / exposure
Acceptance and Commitment Therapy (ACT) is a psychotherapy that has been an effective approach for chronic illnesses. This type of therapy focuses on six core principles that promote psychological flexibility among individuals which include the following: (1) acceptance, (2) cognitive defusion, (3) mindfulness, (4) self as context (5) values (6) committed action. The primary aim of ACT is to help patients with PAH achieve psychological flexibility through learning the skills based on the six core principles.

It is a group-based intervention that will be conducted physically with each group accommodating 8 to 10 participants. There will be 3 groups in total, each lasting two hours and spanning a total duration of six weeks.

The intervention will be conducted by clinical psychologists who are trained in the ACT approach with a minimum of 2 years of experience and with at least 4 years of experience in the field of mental health.
