ABSTRACT

Objective:

To explore the correlation among childhood trauma, obsessive-compulsive symptoms, and implicit and explicit memory in patients with obsessive-compulsive disorder(OCD).

Methods:

Fifty-two OCD patients were enrolled, and the childhood trauma was investigated by using the childhood trauma questionnaire short-form(CTQ-SF). The degree of obsessive-compulsive symptoms was assessed by using the Yale-Brown obsessive symptoms scale (Y-BOCS). In addition, the abilities of implicit memory and explicit memory were tested by vocabulary perception speed tasks and vocabulary recognition tasks.According to the scores of CTQ-SF, the patients were divided into abuse group( n=26) and neglect group( n=26). SPSS 22.0 software was used for t-test and Pearson correlation analysis.

Results:

Results of obsessive-compulsive symptoms, implicit memory, and explicit memory showed no differences between the abuse group and the neglect group( t=-1.959-1.839, P>0.05). The scores of obsessions symptoms(12.52±4.61) were positively correlated with the total scores of CTQ-SF (40.10±10.20)( r=0.331, P<0.05). On the subscale, the scores of obsessions were positively correlated with the scores of physical abuse(7.89±3.02), sexual abuse(6.47±2.28)( r=0.373, P<0.01, r=0.356, P<0.05). There was a negative correlation between the scores of physical abuse and the accuracy of explicit memory(68.75±13.33)( r=-0.281, P<0.05). The scores of physical neglect(8.98±2.67) was positively correlated with implicit memory response time(4 285.94±2 067.42)( r=0.314, P<0.05).

Conclusion:

Obsessions in patients with OCD are related to traumatic childhood experiences, especially physical abuse and sexual abuse.Physical trauma may influence the level of implicit and explicit memory in patients with OCD.
