Objective To explore the influence of Marathon Group Counseling on
members' self-affirmation, and to promote the participation, feasibility and promotion
of group counseling in colleges and universities. Methods Based on self-awareness
theory, self-affirmation training theory, and expressive art therapy, group intervention
is implemented from three stages: group establishment and trust promotion, individual
self-affirmation training and family self-affirmation training. Results (1) Paired sample
t-test found that after participating in Marathon Group Counseling, the level of self-
confidence(t = 2.93, P < 0.05), core self-evaluation(t = -2.54, P< 0.03) and self-esteem
(t = -3.94, P < 0.01)of group counseling members are significantly improved, and
the improvement of core self-evaluation is continuous; (2) Chi-square test found the
number of self-esteem in the test group is significantly higher than that in the control
group. Conclusion Marathon Group Counseling has a positive role in promoting self-
evaluation and self-growth. Compared with traditional group counseling, Marathon
Group Counseling has some advantages in terms of participant participation, time
and economic cost, group counseling feasibility and intervention effectiveness, and is
suitable for university promotion and development.
