Objective: To explore the effect of group cognitive behavioral therapy (GCBT) on cognitive control among college students with high obsessive compulsive traits, to provide basic information for the psychological counseling intervention for college students. Methods: From March to April 2019, 687 students were conveniently selected from 2 universities in Hefei. According to the inclusion and exclusion criteria, 58 students with high obsessive traits were selected and divided into experimental group ( n =29) and control group ( n =29) by random number table method. The experimental group received cognitive behavioral group counseling for 4 weeks (1.5 h each time, twice a week), while the control group receive no intervention. The Obsessive Compulsive Inventory Revised (OCI-R), Stroop Color Word Test (SCWT), Digital Span Test (DST), and Wisconsin Card Sorting Test (WSCT) were used to assess in two groups at baseline and 4 weeks later. Results: After 4 weeks, the scores of OCI-R in the GCBT group (10.28±7.22) was lower than that of in the control group (15.90±10.20) ( t=2.42, P<0.05). Before and after intervention, compared with the control group [(21.89±6.63, 20.52±7.37)s, (8.62±4.43, 8.04±4.84)s] in Stroop C and Stroop interfere effects (SIE), the GCBT group [(22.14±4.92, 16.81±3.43)s, (8.36±3.87, 4.82±1.86)s], the interaction of time group was statistically significant ( F =14.60, 10.54, P <0.05). Compared with the control group (6.21±1.35, 6.55±1.45)times, the scores of DST reverse in the GCBT group (6.31±1.44, 7.24±1.38) times were statistically significant ( F=3.96, P <0.05). Conclusion It suggests that cognitive behavioral group counseling can improve the inhibitory control and working memory of college students with high obsessive compulsive traits, but does not change the cognitive flexibility.

Objective To explore the cognitive process of cognitive flexibility in obsessive-compulsive disorder patients. Methods Thirty-two patients with obsessive-compulsive disorder (OCD) and thirty-two healthy controls were included. The Task Switch paradigm and event-related potentials were used to assess cognitive flexibility. Results The accuracy rate was lower in the OCD than in control group in both repeat and switch trials (P＜0.05). Reaction time analysis revealed significant differences in both repeat and switch between the OCD and controls ( P＜0.05). ERPs revealed significant differences in N2 and P3 amplitudes between OCD and controls (P＜0.05). There was no significant correlation between cognitive flexibility (accuracy rate and reaction time of repeat and switch, and N1, N2 and P3 amplitudes) and clinical forced symptoms in OCD (P＞0.05). Conclusion Obsessive-compulsive disorder of cognitive flexibility by injured.
