To explore the enhancement effect of the Chinese Chess psychological counseling method on the professional competency of psychological counselors. A total of 66 students (n=33, experimental group participating in the Chinese Chess psychological counseling method training) and (n=33, control group not participating in the Chinese Chess psychological counseling method training) were selected from psychological schools for technical training of counselors. The experimental group underwent timely supervision based on the specific actual situation of counselors after intensive training. The General Self-Efficacy Scale (GSES), Maslach Burnout Inventory General Survey (MBI-GS), and Competency Research Scale were used to conduct pre-test, post-test, and follow-up measurement after half a year for both the experimental group and the control group. Independent sample t-tests were used to analyze the differences in various variables between the experimental group and the control group during the pretest, post-test, and follow-up measurement. Paired sample t-tests were used to analyze the changes in various variables between the experimental group and the control group during the pre-test, post-test, and follow-up measurement. What the results show are: (1) Independent sample t-tests showed that there were significant differences in general self-efficacy, job burnout and its sub-dimensions, and competency characteristics and its sub-dimensions between the experimental group and the control group before and after training, as well as after half a year. The experimental group scored significantly higher than the control group in general self-efficacy and competency and its sub-dimensions (p<0.001), while scoring significantly lower in job burnout and its sub-dimensions (p≤0.001). (2) Paired sample t-tests showed no significant differences in general self-efficacy, job burnout and its sub-dimensions, and competency and its sub-dimensions between the control group before and after the test (p>0.05), indicating that there were no statistically significant changes in the research variables of the control group during the pre-test and post-test periods. After half a year, there was no significant change in job burnout scores, while general self-efficacy, competency, and its sub-dimensions scores significantly decreased (p<0.05). (3) Paired sample t-tests showed significant differences in general self-efficacy, job burnout and its sub-dimensions, competency and its sub-dimensions between the experimental group before and after training (p<0.001). After half a year, job burnout scores significantly decreased (p<0.001), while general self-efficacy, competency, and its sub-dimensions scores significantly increased (p<0.001). Therefore, the Chinese Chess psychological counseling method has an enhancement effect on the professional competency of psychological counselors.
