SPS (sum) | 8.0 | 3.2 | 0.24 | 0.8 | t(55.0) = 15.5*, p < .001 |
QIDS (av) | 0.73 | 0.46 | 0.15 | 0.18 | t(64.7) = 7.4*, p < .001 |

Note: *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).
Abbreviations: BAI, Beck Anxiety Inventory; OCD, obsessive–compulsive disorder; QIDS, quick inventory of depressive symptoms; SD, standard deviation; SPS, sensory phenomena scale; Y‐BOCS, Yale‐Brown Obsessive–Compulsive Scale.
