The Efficacy of an SFBT-Based Positive Psychology Intervention in Promoting University Students’ Post-Traumatic Growth and Psychological Resilience After the COVID-19 Pandemic: A Quasi-Experiment

Abstract

Purpose: This study examines the efficacy of a positive psychology intervention involving solution-focused brief therapy (SFBT) techniques in promoting university students' post-traumatic growth and psychological resilience after the COVID-19 pandemic. Methods: The research hypotheses were tested via a quasi-experimental design with pre- and post-tests including three groups: intervention (n = 28), active control (n = 25), and control groups (n = 57). We followed convenience sampling and recruited Chinese students after the peak of the pandemic. Results: Repeated-measures ANOVA revealed that there were significant main effects of groups in post-traumatic growth, F(2, 107) = 3.17, p < .05, η² = .05, and psychological resilience, F(2, 107) = 4.19, p < .05, η² = .06. The SFBT-based positive psychology intervention significantly increased both positive outcomes in the intervention group. Discussion: By applying SFBT techniques in positive psychology interventions, pandemic experiences can become an opportunity for students' positive growth.
