Background: Reinforcement sensitivity theory is a neurocognitive theory of personality that strives to explain the underlying structure of personality.

Aim: The present study aimed to address this issue by assessing the behavioral systems of revised-RST, i.e., BIS, BAS, fight, flight, and freeze among four populations.

Methods: Participants included 235 out-patients, of these, 54 met the DSM-5 criteria for OCD, 65 for GAD, 72 for SAD, and 44 for PD. Further, 82 healthy controls were recruited and matched on education and age. Then, participants completed demographic information and several questionnaires in Persian. The Kolmogorov-Smirnov, Chi-squared analyses, the independent t-tests, and MANCOVA was used to compare demographics and clinical variables in five groups.

Results: The mean score of GAD in r-BAS was higher than the other abnormal groups, but the mean score of r-BIS was higher for the OCD group. In addition, the PD group experienced the highest Fight as well as Flight mean score. Also, the GAD group experienced the highest mean score of Freeze. The greatest effect size was for r-BAS, whereas the effect size of the groups for Flight and Freeze was lower than the other scales.

Conclusions: More nuanced knowledge from RST may be helpful in the diagnosis, etiology, and continuation of common mental disorders. The results may help us understand better the personality-related psychopathology underlying OCD as well as anxiety disorders.
