Note. Correlations in bold are statistically significant at p < .001. Correlations in italics are statistically significant at p < .05. Correlation coefficients were estimated based on varying sample sizes (ns = 125 to 653) as some measures were only administered to participants who endorsed specific diagnoses. OASIS = Overall Anxiety Severity and Impairment Scale. BSI-A = Brief Symptom Inventory – Anxiety Subscale. PDSS = Panic Disorder Severity Scale (self-report version). SPIN = Social Phobia Inventory. PCL-C = Posttraumatic Stress Disorder Checklist –Civilian Version. GADSS = Generalized Anxiety Disorder Severity Scale. PHQ-9 = Patient Health Questionnaire 9 (depression scale). SF-12-M = Short Form Health Survey – Mental Health Subscale. SDS = Sheehan Disability Scale. EQ-5D = EuroQol (quality of life scale). SF-12-P = Short Form Health Survey – Physical Health Subscale. MOS-SSS = Medical Outcomes Survey – Social Support Scale. AUDIT = Alcohol Use Disorders Identification Test.
