Preliminary Analysis
In the undergraduate sample, approximately half of the participants (56.1%, n = 23) reported a lifetime history of NSSI. The mean score on emotion dysregulation was 84.60 (SD = 25.23), with those having a NSSI history reporting significantly higher scores,t (37) = -3.29, p =.002 (NSSI history, M = 95.50,SD = 18.26; no NSSI history, M = 73.65, SD = 23.15). In the community sample, approximately half of participants (55.2%, n = 91) reported a lifetime history of NSSI. The mean score on the measure of emotion dysregulation was 105.88 (SD = 19.30), with those having a NSSI history reporting significantly higher scores, t (163) = -2.53, p = .01 (NSSI history, M = 109.25, SD = 18.81; no NSSI history, M = 101.74, SD= 19.22). The two samples did not significantly differ with regard to percent of the sample endorsing NSSI, χ2 (1, N= 206) = .01, p = .91; however, samples did significantly differ on mean levels of emotion dysregulation, t (204) = -5.58, p<.001, with the community sample endorsing higher levels of emotion dysregulation.
