“…These include tools such as the Scale for Assessing Emotional Disturbance (SAED; Epstein & Cullinan, 1998), the Differential Test of Conduct and Emotional Problems (DT/ CEP; Kelly, 1990), and the Emotional and Behavior Problem Scale (EBPS; Wright, 1989). Serious questions remain about the discriminant validity of such assessment tools (Costenbader & Buntaine, 1999;Olympia et al, 2004). For example, the DT/CEP and EBPS have been used for their ability to differentiate between ED and social maladjustment, but Costenbader and Buntaine (1999) found that the DT/CEP failed to identify 79% of students who were previously classified with ED, and the EBPS incorrectly identified about 50% of students with social maladjustment who previously did not meet this exclusion criterion.…”
