This study conducted a systematic literature review and meta-analysis of 54 quantitative group studies published between 2001 and 2020, exploring three key questions: What is the overview of the application of group-creating factors in practical settings? How do these factors relate to group effectiveness? Do group-creating factors such as theoretical approaches, group structure, members and leaders contribute to achieving change effects? The findings reveal that research topics are diverse, with self-related issues being the most common. Groups typically consist of 8-12 members, meet once a week, for a total of 5-8 sessions and 16 hours, with cognitive, action-oriented, or goal-oriented approaches preferred. Most members are adults, over half are normal and healthy individuals, and the majority are mixed-gender groups, led by school teachers, counselors, or graduate students. Both immediate and sustained effect sizes are statistically significant and moderate, indicating positive impacts on the mental health and behavior of group members. Furthermore, member sex, age, and group topics significantly correlate with immediate effect size, while theoretical orientation, member age, group topics, and total hours significantly correlate with sustained effect size. These findings provide valuable insights for group design and practice, offering recommendations for future research and group education. |
