Means and standard deviation by group on symptom measures

Symptom Measures OCD
M (SD)		 NCC
M (SD)		 t d
DOCS 31.93 (15.95) 5.40 (4.71) 8.73 1.50
STAI - T 53.66 (10.41) 35.50 (8.73) 7.32 1.37
ACS-Focus 20.06 (5.35) 26.00 (4.08) 4.77 1.06
ACS-Shift 27.26 (5.22) 32.51 (4.22) 4.23 0.97

Note: all t-values significant at p < .001. OCD = Obsessive Compulsive Disorder; NCC = Non-clinical control; DOCS = Dimensional Obsessive-Compulsive Scale; STAI–T = State Trait Anxiety Inventory – Trait Subscale; ACS = Attention Control Scale. Cohen’s d was calculated as the difference between the mean scores in each group divided by the pooled standard deviation.
