【 摘 要 】

Background and aims: Obsessive-compulsive (OC) disorder patients are impaired in disengaging attention from negative valence stimuli and show an attentional bias toward the right space. This pattern in OC disorder is similar to the impaired disengagement of attention from stimuli in the ipsilesional space as a consequence of a right-hemispheric cerebral lesion in neglect patients, suggesting a right-hemispheric dysfunction in OC disorder patients. The attentional impairment in neglect patients is reduced by a visuo-motor procedure as prismatic adaptation (PA) with right-deviating lenses. Thus, here we explored whether right-deviating-PA is also effective in reducing OC psychological symptoms. Methods: Participants with high rate of OC symptoms, completed self-report measures of such symptoms before and after right- or left-deviating-PA. Results: Right-deviating, and not left-deviating-PA, reduced OC symptoms more prominently on obsessions than compulsions. Conclusions: Results support the idea that right-deviating-PA might be considered as an effective technique to modulate OC symptoms. This has implications for theories about the underlying mechanisms of OC symptoms and for the consideration of PA as a complementary procedure to psychological treatments.
