Earlier research has demonstrated that alcoholics with or without attention deficit disorders, residual type (ADDRT) can be differentiated by Minnesota Multiphasic Personality Inventory (MMPI) Clinical Scale Profiles. This study addressed the question of whether that differentiation was made by virtue of subtle or obvious aspects of the MMPI item pool. Groups of 30 of male alcoholics with or without ADDRT were individually matched on age and education variables. Statistically significant differences were found for the D-O, HY-O, HY-S, PD-O, PA-O, PA-S, MA-O, MA-S, ES and A scales.
Earlier research had demonstrated that alcoholics with attention deficit disorder residual type (ADDRT) differ from other alcoholics on the Minnesota Multiphasic Personality Inventory (MMPI). The purpose of this study was to explore the influence of drug abuse on the relationship of ADDRT and alcoholism as reflected on the MMPI. Groups of 48 male alcoholics, 28 ADDRT alcoholics, 25 ADDRT alcohol and drug abusers and 18 alcohol and drug abusers were all administered the MMPI. Significant differences were found between the alcoholic and ADDRT alcoholic groups on scales Pd, Sc, Si, F, and K. For the ADDRT alcohol and drug abusers versus the alcohol and drug abuser groups, they differed on scales K, Hs, D, Pd, Pa, Pt, Sc, Si, F, K, and L.
Recent research studies have attempted to explore various aspects of attention deficit disorder and substance abuser subtypes. The purpose of the present study is to evaluate the effect of drug abuse on MMPI scale score profiles of alcoholics with or without attention deficit disorder symptoms. For the alcoholic group with ADDRT versus the alcoholic group with ADDRT and drug abuse there were no significant differences between the groups. The hypothesis that the factor of drug abuse would account for MMPI score differences between alcoholics with or without ADDRT failed to be supported. Regardless of whether or not the subject groups contained drug abusers or not, the ADDRT-diagnosed groups demonstrated clinically significant levels of psychopathology on the MMPI profiles. These results would suggest that the variable of ADDRT diagnosis is probably an important factor to consider in substance abuser populations.
Programs for the computer analysis and interpretation of neuropsychological test data have been developed in recent years. In this paper, a new computer program, with initial validation data, is presented. Diagnostic hit rate for brain damage was 80% (52 of 65). For the extent of brain damage the hit rate was 60% (12 of 20). When laterality was considered, the hit rate was 71% (10 of 14). These results are comparable with computer programs for data from the Halstead-Reitan Neuropsychology Test Battery.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
