“…Individuals who are diagnosed as psychotic have lost touch with reality, often experience hallucinations (seeing or hearing things that are not occurring) and delusions (bizarre beliefs), and behave inappropriately. Most studies report that JHOs are rarely psychotic (see, e.g., Bailey, 1994;Corder, Ball, Haizlip, Rollins, & Beaumont, 1976;Cornell, 1989;Cornell et al, 1987bCornell et al, , 1989Dolan & Smith, 2001;Ewing, 1990;Hellsten & Katila, 1965;Kashani, Darby, Allan, Hantke, & Reid, 1997;King, 1975;Labelle et al, 1991;Malmquist, 1971;Myers et al, 1995;Myers & Kemph, 1988Patterson, 1943;Petti & Davidman, 1981;Russell, 1965Russell, , 1979Shumaker & McKee, 2001;Sorrells, 1977;Stearns, 1957;Walshe-Brennan, 1974Yates, Beutler, & Crago, 1983; with respect to adolescent mass murderers, see Meloy, Hempel, Mohandie, Shiva, & Gray, 2001). Some studies, however, do posit a high incidence of psychosis (see, e.g., Bender 1959;Lewis, Pincus et al, 1988;Rosner, Weiderlight, Rosner, & Wieczorek, 1978;Sendi & Blomgren, 1975) or episodic psychotic symptomatology (Lewis et al, 1985;Lewis, Lovely et al, 1988;Myers et al, 1995;Myers & Scott, 1998) and other serious mental illness, such as mood disorders (Lewis, Pincus et al, 1988;Malmquist, 1971Malmquist, , 1990.…”
