Autism is a neurodevelopmental disorder characterized by social interaction and verbal communication deficits. Students with autism face various psychological difficulties in the college environment, such as social difficulties, emotional fluctuations, and limited cognitive function. This study aims to help autistic students develop their psychology and improve their quality of life.

This study tried to carry out psychological extension training in college sports, and 50 students with autism were set as research objects. Half of the students received psychological extension training in the physical education course, and the other half received traditional behavioral intervention therapy in the physical education course. Both groups of students received one semester of therapeutic training. Results SPSS23.0 software was used for psychological data correlation statistics, P>0.5 indicated strong correlation and P<0.5 indicated medium weak correlation.

The experimental results showed that after one semester of treatment training, the number of autistic students in the experimental group was reduced to 12. The overall mental state was good, and the cultivation of positive psychology was more effective. At the same time, the average test score was higher. However, the number of students with autism in the control group remained high at about 20, and the P-value was still greater than 0.5.

The psychological development training proposed in this study can provide theoretical and practical guidance for cultivating autistic students’ positive psychology to improve their overall mental health level.
