“…Assessments developed to aid in the differentiation between ED and SM include the Clinical Assessment of Behavior (CAB; Bracken & Keith, 2004), Emotional Disturbance Decision Tree (EDDT; Euler, 2007), Scale for Assessing Emotional Disturbance (SAED; Epstein & Cullinan, 1998), Emotional and Behavior Problem Scale (EBPS; Wright, 1989), and the Differential Test of Conduct and Emotional Problems (DT/CEP; Kelly, 1990). In spite of the presence of these measures, researchers have established that students with ED cannot be reliably differentiated from students with SM (Constenbader & Buntaine 1999; Dumont & Rauch, 2000; Easler & Medway, 2004; Merrell & Walker, 2004; Olympia et al, 2004; Stein & Merrell, 1992) because youth with characteristics associated with most definitions of SM (e.g., exhibiting behavior that is difficult to manage, aggressive, truant) are likely to have co-occurring conditions such as depression, anxiety, and PTSD (Davis, Sheeber, & Hops, 2002; Seeley, Rohde, Lewinsohn, & Clarke, 2002). Thus, those students who exhibit behavior consistent with many conceptualizations of SM are the same students as those who have the emotional and behavioral problems associated with ED.…”
