Comparison of brain-behavioral systems (BAS/BIS), adjustment components and schizoid personality syndrome in patients with migraine and nervous peptic ulcer and normal subjects

Introduction: Migraine and nervous peptic ulcer are common psychosomatic diseases, that various psychological factors are effective in their occurrence and exacerbation. Aim: The purpose of this study was to compare the Brain Behavioral Systems (BAS/BIS), adjustment components and schizoid personality syndrome in patients with migraine and nervous peptic ulcer and normal subjects. Method: The method of this research was comparative causative research. The statistical population of this study was all patients over 18 years of age with nervous peptic ulcer and migraine who referred to Bukan medical centers in 2019 and their normal counterparts. The sample size was 90 people. 30 patients over 18 years old were assigned to each group by simple random sampling and their normal counterparts were also selected by available sampling method. Carver and Whites BIS/BAS Scales, Bells adjustment inventory and Millon clinical multiaxial inventory (MCMI-III) were provided for data collection. Data analysis was done by MANOVA and ANOVA method, using SPSS-PC (v.22). Results: Migraine patients had significantly higher mean of schizoid personality disorder symptoms and BAS/BIS than the other two groups (p<0.05). Both groups of patients had significantly lower mean in adaptation than normal subjects (p<0.05). Conclusion: Both groups of disease had the lowest rate of adjustment components. The findings also imply that the Migraine patients had the highest rates of schizoid personality syndrome and BAS/BIS.
