“…Alcoholics in treatment typically are older than drug abusers in treatment (Keskinen, 1987; cf. Method section), and age is known to be correlated with MMPI scores in both the general psychiatric population (e.g., Aaronson, 1958; Gynther & Shimkunas, 1966; Schenkenberg, Gottfredson, & Christensen, 1984) and among alcoholics (Delatte & Delatte, 1984; Faulstich, Carey, Delatte, & Delatte, 1985; Filstead, Drachman, Rossi, & Getsinger, 1983; Graham & Strenger, 1988; McGinnis & Ryan, 1965; McLachlan, 1975; Penk, Charles, et al, 1982; Wilson, Mabry, Khavari, & Dalpes, 1977). In both the general psychiatric population and among alcoholics, MMPI scales Hypochondriasis ( Hs ) and Depression ( D ) are usually higher in older subjects and scales F , Psychopathic Deviate ( Pd ), Psychasthenia ( Pt ), Schizophrenia ( Sc ), and Hypomania ( Ma ) are usually lower in older subjects.…”
