“…Five studies reported total severity scores, which were based on the RFQ (Poletti et al, 2017), the CAQ (Green et al, 2014), the CTQ (Marshall et al, 2016; Mansueto et al, 2017), and information retrieved from medical charts and non-standardized interviews (Schenkel et al, 2005). Thirteen studies used a composite score of severity and frequency and used dichotomous variables of CT exposure of (1) low versus high levels (Poletti et al, 2017; Aas et al, 2012b; Shannon et al, 2011; Mansueto et al, 2017), (2) absent versus high levels (Bucker et al, 2013; Kelly et al, 2016), (3) absent versus existent levels (van Os et al, 2017; Green et al, 2014; Green et al, 2015; McCabe et al, 2012; Schenkel et al, 2005) or (iv) below versus above the median split (Aas et al, 2012b) for the subscales or total scores. However not all studies reported mean group-level data for these measures.…”
