In stage 2, the difference between OCD hoarders and controls reaching criterion just approached significance ( χ 2 (1)=3.77, p =0.05), and the difference between the hoarding disorder and control groups was significant ( χ 2 (1)=7.31, p <0.01) (see Fig. 2 A).
Hoarders who scored below the median anxiety score demonstrated significant impairments in TOL, set shifting, PRL, and marginal significance in SSRT ( p <0.06), replicating the results reported in Table 2 .
Similar group differences were found (although SSRT now became marginally significant ( p <0.08)), suggesting the present findings were unlikely to result from comorbid depressive symptoms.
