than trying new things; his sensitivity to the potential rewards of trying new things appears to be blunted or at least overshadowed by exaggerated anticipation of potential punishment (feeling bad). Similarly, previous studies have reported clinically significant levels of anhedonia, conceptualized as the inability to experience pleasure and reduced sensitivity to rewards, in OCD patients, which predicted OCD symptom severity independently of depression symptoms [138–139]. Previous work has also indicated that a proportion of patients with OCD report feelings of reward and positive affect following the completion of compulsive behaviors [24, 38].
