Abstract:
Objective To explore the attentional biases in individuals with different types of obsessivecompulsive symptom and the correlations between the attentional bias of high obsessive compulsive symptom (HOC) and symptoms. Methods 22 individuals with HOC and 38 individuals with low obsessive compulsive (LOC) symptom completed the Chinese Emotional Stroop task that assessed the attentional bias. Comparisons were made between HOC and LOC and in different types of HOC, and the correlations between the attentional bias of HOC and symptom severity scores were searched for. Results The comparison between HOC and LOC on the reaction time of neutral, negative and disgust-related words were not significant. The contamination/washing subtype in HOC showed faster reaction time on negative and disgust-related words compared to that of neutral words,and its attentional bias exhibited significant correlation with symptom severity scores( r= -0. 648, P=0. 031 ). Conclusion Such information point out the contamination/washing subtype may have a different neural mechanism compared to the other subtypes of OCD.
