Description: This study will examine if and how anger and depressive rumination are differentially associated with internalizing and externalizing disorders, and patterns of gender differences in these relationships. Using participants recruited from the Colorado Longitudinal Twin Study (LTS; for additional details about this sample, see Rhea, Gross, Haberstick, & Corley, 2013; Rhea, Gross, Haberstick, & Corley, 2006), we will use the anger rumination scale (ARS; Sukhodolsky, Golub, & Cromwell, 2001), the rumination-reflection questionnaire (RRQ; Trapnell & Campbell, 1999), and the ruminative response scale (RRS; Treynor, Gonzalez, & Nolen-Hoeksema, 2003) as measures of anger and depressive rumination. In terms of psychopathology, we will include measures of generalized anxiety disorder, major depressive disorder, antisocial personality disorder from the Diagnostic Interview Schedule (DIS; Robins, Cottler, Buckolz, Compton, North, & Rourke, 2000), and measures of substance dependence/abuse from the Composite International Diagnostic Interview – Substance Abuse Module (CIDI-SAM; Cottler, Robins, & Helzer, 1989).
