Abstract
OBJECTIVE: Sensory overresponsivity (SOR) is characterized by challenges in integrating and responding to everyday sensory experiences. Obsessive-compulsive disorder (OCD) is characterized by intrusive thoughts, ritualistic behaviors, and sensory phenomena. There is some evidence that individuals with co-occurring symptoms of SOR and OCD experience more severe anxiety than those with symptoms of OCD alone, but most studies employed small numbers of participants (typically with an OCD diagnosis) assessed at a single time point. Our 2-fold objective was to replicate previous research showing an association between OCD symptoms and SOR symptoms concurrently and to extend these analyses longitudinally in a large, birth-register-based sample. METHOD: Twins (N = 1613) and their primary caregivers participated in a multimodal, multimethod, longitudinal study. Primary caregivers completed the SOR inventory for their offspring at the age of 8 years, and twins completed the adult sensory profile at the age of 13 years. Parents completed the OCD module of the Diagnostic Interview Schedule for Children-IV when twins were 8 years; twins completed the same module at 13 years. Linear regression models tested for the concurrent and longitudinal associations between SOR and OCD controlling for socioeconomic status. RESULTS: Concurrently, participants' likelihood of exhibiting OCD symptoms increased with each symptom of tactile or auditory overresponsivity at 8 years and 13 years (odds ratio = 1.1-2.7). However, SOR measured at age 8 years was unrelated to adolescent OCD symptoms at 13 years and vice versa. CONCLUSION: SOR symptoms, although significantly related to concurrent OCD symptoms, do not appear to precede OCD symptoms, suggesting that SOR symptoms may reflect another type of OCD sensory phenomenon rather than a comorbid condition.
