The CTQ is a 28-item, retrospective screening tool used to detect the occurrence and frequency of emotional, physical, and sexual abuse as well as emotional and physical neglect before the age of 17 (α = 0.613 for total scale). The instrument's five subscales, each representing a type of abuse or neglect, have robust internal consistency and convergent validity with a clinician-rated interview of childhood abuse as well as with therapists' ratings of abuse (Scher et al. 2001). The MASQ-SF is a 62-item scale that includes four subscales: general distress anxious symptoms, general distress depressive symptoms, anxious arousal and anhedonic depression. The 22-item AD subscale is an instrument assessing low levels of positive affect and other factors that represent depression specifically (i.e. not general negative affect; Hughes et al. 2006). One item was excluded from this questionnaire in our sample (‘thoughts about death or suicide’) to be compliant with the Duke University IRB (α = 0.899 for anhedonia subscale). The GDD subscale includes 12 items (α = 0.930 for GDD subscale) reflecting negative affect that occur in both depression and anxiety
