OCD=Obsessive-Compulsive Disorder; SD=standard deviation; Y-BOCS=Yale-Brown Obsessive-Compulsive Scale; SPS=Sensory Phenomena Scale; QIDS=Quick Inventory of Depressive Symptoms; BAI=Beck Anxiety Inventory.

Levene’s Tests for Equality of Variances revealed unequal variance between the groups for Y-BOCS, SPS, QIDS, and BAI scores; degrees of freedom for these tests are adjusted using Satterthwaite’s approximation. Scores for the Y-BOCS and SPS reflect the sum of individual rating scales; scores for the QIDS and BAI are the average (av) of responses to the individual questions (total average scores can range from 0 to 3).
