“…Specifically, various samples of individuals working with populations with developmental disabilities included direct care staff scoring an average of 51% (Furtkamp, Giffort, & Schiers, 1982); professionals including nurses, occupational therapists, psychiatrists, and physiotherapists obtaining 49% (Sturmey, Newton, Milne, & Burdett, 1987); and school staff achieving a mean of 52% (Sturmey et al, 1987). However, community mental health agency therapists' mean kbpac score of 64% is somewhat higher than the 43% obtained by parents in this study (Herschell, 2004). The majority of therapists (almost 90%) in Herschell's study (2004), however, had masters-level degrees, while parents in the present study reported, on average, completing “some college.” These discrepancies in education and scores on the kbpac between the present study and Herschell (2004) may support the idea that education, particularly education in mental health, increases knowledge of behavioral principles.…”
