“…The subjects of these investigations frequently have been lower-socioeconomicstatus men from a single state hospital or Veterans Administration treatment program (Bean & Karasievich, 1975;Goldstein & Linden, 1969;Nerviano, 1976;Skinner, Jackson, & Hoffman, 1974;Stein, Rozynko, & Pugh, 1971). As noted above, the typing dimensions usually have been personality variables (Lawlis & Rubin, 1971;Nerviano, 1976;Nerviano & Gross, 1973;Partington & Johnson, 1969;Skinner et al, 1974;Stein et al, 1971)-often from the Minnesota Multiphasic Personality Inventory (MMPI; Bean & Karasievich, 1975;Goldstein & Linden, 1969;Mogar, Wilson, & Helm, 1970;Whitelock, Overall, & Patrick, 1971). Typically, the typology is related to few other variables, so the types remain relatively unelaborated, and the issues of their differential development and prognoses are not explored (but see Partington & Johnson, 1969).…”
