“…The advantages of the clinical interview may be a function of both the probing questions it contains about perceptual, ideational and mood symptoms, as well as the clinical training of the rater. Consistent with this speculation, some earlier research on general clinical samples comparing the predictive power of structured diagnostic interviews with parent-reported behavior problems indicates that structured interviews have higher positive predictive power and greater validity (Wassenberg, Max, Koele, & Firme, 2004; Reitman, Hummel, Franz, & Gross, 1998). Also, it has been argued that while externalizing problems are more readily observable because the problem behaviors are directed toward others, internalizing problems are relatively poorly recognized by parents (Bird, Gould, & Staghezza, 1992; Sourander, Helstela, & Helenius, 1999).…”
