“…Greater risk of prisoner maladjustment and SIB in ADSEG is generally assumed (Bonta & Gendreau, 1990;Correctional Association of New York, 2004;Craig, 2003;Haney, 1993;Haney & Lynch, 1997;Johnson, 1976;532 E. Lanes O'Keefe, 2008;Rhodes, 2005;Salive, Smith, & Brewer, 1989;Sykes, 1958). Consider, however, the findings that (a) a majority of all successful prisoner suicides occur in segregation housing (Mumola, 2005;White, Schimmel, & Frickey, 2002), (b) mentally ill prisoners find themselves housed for longer periods of time in ADSEG than nonmentally ill prisoners (Correctional Association of New York, 2004;Stone, 2003), and (c) many prisoners in ADSEG are relatively younger, less educated, more prone to substance abuse, have more extensive offense histories, and are more impulsive and hostile, easily frustrated, and experience higher rates of housing problems within prison than nonsegregated prisoners (Haney, 1993;Lovell, Cloyes, Allen, & Rhodes, 2000;Motiuk & Blanchette, 1997;O'Keefe, 2008;Sykes, 1958;Toch & Kupers, 2007;Zinger & Wichmann, 1999).…”
