Abstract

This study aims to systematically review randomized controlled trials that evaluate the effectiveness of group Acceptance and Commitment Therapy (ACT) in treating depressive symptoms. Studies published between January 2004 and June 2025 in English and Turkish languages were searched in databases such as Medline, PsycArticles, PubMed, Scopus, Web of Science, and TR Index. Ultimately, 17 studies meeting the inclusion criteria were included in this systematic review. In the studies, the intervention ranged from a minimum of 4 sessions to a maximum of 12 sessions. Most commonly, the interventions were implemented over 8 sessions. The studies included in this review utilized standardized measurement scales. Findings suggest that group-based Acceptance and Commitment Therapy is effective in reducing depressive symptoms and that this effect persists at follow-up measurements. As a result, group-based Acceptance and Commitment Therapy was found to be effective in treating depressive symptoms. Although most of the included studies had limited sample sizes and heterogeneous gender distribution, the inclusion of diverse groups -such as cancer patients, military personnel, and menopausal women- increases the generalizability of the findings. The results are clinically important because group therapy interventions are cost-effective and increase access to effective treatment for individuals.

Özet

Bu çalışmada depresif belirtilerin tedavisinde grup temelli Kabul ve Kararlılık Terapisinin etkililiğini ele alan randomize kontrollü çalışmaların sistematik olarak incelenmesi amaçlanmıştır. Ocak 2004 ile Haziran 2025 yılları arasında yayımlanmış, İngilizce ve Türkçe dillerindeki çalışmalar; Medline, PsycArticles, PubMed, Scopus, Web of Science ve TRDizin veri tabanlarında taranmıştır. Tarama sonucunda dahil etme kriterlerine uyan 17 çalışmaya bu sistematik derlemede yer verilmiştir. Bu çalışmalarda müdahale, en az 4 oturumdan en fazla 12 oturuma kadar değişiklik göstermiştir. Müdahalelerin çoğunlukla 8 oturum halinde uygulandığı görülmektedir. Bu derlemeye dahil edilen çalışmalarda standardize ölçüm araçları kullanılmıştır. Çalışmaların bulguları, grup temelli Kabul ve Kararlılık Terapisi’nin depresif belirtileri azaltmada etkili olduğunu ve izlem ölçümlerinde de bu etkinin devam ettiğini ortaya koymuştur. Sonuç olarak, grup temelli Kabul ve Kararlılık Terapisi’nin depresif belirtilerin tedavisinde etkili olduğu bulunmuştur. Dahil edilen çalışmaların çoğunda örneklem büyüklüğü sınırlıdır ve cinsiyet dağılımı heterojendir; ancak kanser hastaları, askerler, menopoz dönemindeki kadınlar gibi çeşitli örneklemleri kapsıyor oluşu genellenebilirliği artırmaktadır. Grup terapi müdahalelerinin maliyet-etkinlik açısından avantajlı oluşuyla ilişkili olarak etkili tedaviye erişimi artırmaları nedeniyle, bu sonuçlar klinik açıdan önem taşımaktadır.
