“…Clinically speaking, the existence of many disorder-specific interventions (i.e., single-disorder protocols [SDPs]) places additional burden on clinicians to learn and administer different SDPs, contributing to clinician burnout and preventing patients from receiving care that they need (Kazdin, 2008;Kazdin & Blase, 2016;McHugh & Barlow, 2010). Recently, researchers have begun to more comprehensively investigate the degree to which aversive reactivity constructs relate to neuroticism (Naragon-Gainey & Watson, 2018), to one another (Conway et al, 2020;Spinhoven et al, 2017), and to other related constructs such as emotion dysregulation (Conway et al, 2020;Juarascio et al, 2020). From a clinical perspective, empirical efforts to compare transdiagnostic cognitive-behavioral interventions (i.e., the Unified Protocol [UP]) to disorder-specific protocols demonstrated that the UP resulted in equivalent symptom reduction, suggesting equal effectiveness with less attrition and less clinician burden (Barlow et al, 2017).…”
