The complex social and family environment puts some college students under significant psychological pressure and stimulation and some students experience Post Traumatic Stress Disorder (PTSD). If not intervened in a timely manner, it will cause significant harm to students’ physical and mental health and even threaten the stability of the campus. From the perspective of educational psychology, collaborative education of ideological and political education for college students can improve the timeliness of ideological and political education, and is of great significance for timely intervention of students’ psychological issues. It can be applied to students PTSD intervention.

The study conducted selection and grouping of 60 PTSD students, resulting in a control group (30) and an intervention group (30). The former adopts general ideological and political education, while the latter adopts a collaborative education strategy for college students’ ideological and political education, lasting for 3 months. PTSD was evaluated using indicators such as the Self-rating Scale for Post-traumatic Stress Disorder (PTSD-SS), and SPSS23.0 software was used to process data.

After 3 months of teaching, the PTSD symptoms of the two groups were improved significantly. Unlike the control group, the intervention group had lower PTSD-SS scores (P<0.05).

Combined with educational psychology, after the implementation of the collaborative education strategy for ideological and political education among college students, the symptoms of PTSD students have been alleviated to varying degrees, and the sleep quality of students has been greatly improved.
