“…The Brief Symptom Inventory-18 (BSI-18; Derogatis, 2001) is an 18-item Self-Report Checklist measure developed as a brief screen for psychological symptoms in medical patients. The BSI-18 has been widely used in research and clinical applications with a variety of patient populations (e.g., Derogatis & Melisaratos, 1983; Mustanski, Garofalo, Herrick, & Donenberg, 2007; Petkus et al, 2010; Serber et al, 2012), including oncology samples (Bober et al, 2013; Galdon et al, 2008; Kwak et al, 2013b; Merport, Bober, Grose, & Recklitis, 2012; Michel, Rebholz, von der Weid, Bergstraesser, & Kuehni, 2010; Michel & Vetsch, 2015; Zabora, 2015; Zabora et al, 2001; Zeltzer et al, 2009). Application of the BSI-18 to oncology patients is supported by its brevity, its coverage of the critical areas of anxiety and depression, and the published manual’s inclusion of normative data for an oncology sample.…”
