“…Rather, the data suggest that preference for street drugs varies over time and as a function of the demographic characteristics of the sample, similar to patterns in the general population (Mueser, Yarnold, & Bellack, 1992). Similarly, people with schizophrenia often report the same reasons for their drug use as primary substance abusers: using to cope with negative affective states, interpersonal conflict, and social pressures (Bradizza, Stasiewicz, & Carey, 1998; Dixon et al, 1991; Krausz, Mass, Haasen, & Gross, 1996; Noordsy et al, 1991; Pristach & Smith, 1996; Sandberg & Marlatt, 1991), as well as reasons related to socialization and boredom (Carey et al, 1999; Mueser et al, 1995; Warner et al, 1994). The situational context seems to be an important determinant of substance abuse for people with schizophrenia, as it is for other abusers (McCrady, 1993), with findings that about half of alcohol abuse occurs in a social context (Dixon Haas, Weiden, Sweeney, & Francis, 1990).…”
