Note. Item-level data are presented for the CBCL OCS subscale. The number (percent) of participants endorsing each CBCL item response option (0, 1, or 2) presented for the full sample and split by the presence/absence of a K-SADS lifetime OCD diagnosis. The first four items are drawn from the Thought Problems subscale (#9, 66, 84, 85) and the latter four items are drawn from the Anxious/Depressed subscale (#31, 32, 52, 112). The number (percent) of participants with a raw sum score>0, >1, or ≥ 5 are also presented. All differences between those with and without lifetime OCD are p<.001 significant in this table.
