“…Each item was rated on a Likert scale indicating the degree to which the participant was bothered or distressed by the symptom in the past 4 weeks (0 = not at all , 4 = extremely ; α = .98). We were particularly interested in the SCL-90-R GSI as it is a validated and common index of general psychological distress (e.g., Marshall, Schell, & Miles, 2010; Metzger et al, 2004; Øiesvold, Bakkejord, & Sexton, 2011) and allowed us to assess reactions to stress (e.g., exams) that could involve various clinical symptoms. This measure was previously used to assess clinical and treatment outcomes among depressed and other clinical and nonclinical populations (e.g., Baer, 2003; Carryer & Greenberg, 2010; Ogles, Lambert, & Sawyer, 1995).…”
