Group-based ACT for Psychological Distress of Young People

This clinical study investigates the effectiveness of two psychological treatment formats for young people aged 16-25 with symptoms of depression, anxiety, stress, or interpersonal difficulties. The study compares group-based Acceptance and Commitment Therapy (ACT) with treatment as usual (TAU), most frequent that would be individual psychotherapy, both of which are established treatment approaches. The study uses a randomized controlled design (RCT), in which participants are randomly assigned to one of the two treatment conditions. This allows for a systematic comparison of treatment outcomes between ACT delivered in a group format and standard individual therapy. The ACT group intervention consists of a structured program in which participants meet regularly over a defined treatment period. The treatment focuses on processes such as psychological flexibility, acceptance of internal experiences, and engagement in actions aligned with personal values. The individual therapy condition consists of one-to-one sessions with a clinician, following standard therapeutic practice. Treatment content and duration are tailored to the participant's clinical presentation and therapeutic needs. Outcome measures include standardized assessments of mental health symptoms, functioning, and psychological processes. These assessments are conducted at baseline, during the treatment period, at post-treatment, and at follow-up time points. Data collected from these measures will be used to evaluate changes over time and differences between the two treatment conditions. The primary aim of the study is to determine whether group-based ACT is as effective as, or more effective than, individual psychotherapy for young people receiving mental health services. The results are expected to contribute to improved knowledge about treatment options for this age group and inform future clinical practice.
