MMPI profiles of adolescent substance abusers in treatment

The non-K-corrected MMPI profiles of 243 adolescents presenting themselves for chemical dependency treatment in a residential setting were examined. Results suggested a general lack of psychopathology in this population, although a significant elevation on the Pd scale did emerge. These data are compared to the findings of previous studies with both adolescent and adult populations.     

The MMPI, prototypal typology, and borderline personality disorder

This study demonstrates inherent features in the DSM-III diagnostic criteria for personality disorders (i.e., overlapping diagnoses and heterogeneous symptomatology) that limit efforts to identify a sensitive and specific MMPI profile for the borderline personality disorder. A sample of 71 inpatients was administered an MMPI and a semistructured interview that systematically evaluated each of 81 symptoms for the 11 DSM-III personality disorders. Interrater reliability was substantially higher than has been obtained with unstructured interviews. The effect on the borderline MMPI profile of variation in the number of borderline symptoms and overlap with the schizotypal, histrionic, and antisocial diagnoses was demonstrated. We discuss implications with respect to a prototypal model of classification.     

Cognitive modeling analysis of decision-making processes in cocaine abusers

This article examines the theoretical basis of decision-making deficits exhibited by cocaine abusers in a laboratory decision-making task first described by Bechara, Damasio, Damasio, and Anderson (1994). A total of 12 male cocaine abusers and 14 comparison subjects performed the task, and the cocaine group performed significantly worse than the comparison group. A cognitive modeling analysis (Busemeyer & Stout, 2002) was used to estimate three parameters that measure importance of the cognitive, motivational, and response processes for determining the observed performance deficit. The results of this analysis indicated, for the first time, that motivational and choice consistency factors, but not learning/ memory were mainly responsible for the decision-making deficit of the cocaine abusers in this task.     

MMPI characteristics of drug abusers with and without histories of suicide attempts

Compared to drug addicts without histories of suicidal attempt (n = 50), drug addicts who have attempted suicide (n = 50) were characterized by higher levels of maladjustment--particularly in the areas of depression, feelings of alienation, and use of projection and externalization--and were more emotionally withdrawn. Certain Minnesota Multiphasic Personality Inventory (MMPI) codetypes appeared in the attempt group that were not present in the no history group. Drug addicts with suicidal ideation but no history of attempt (n = 13) were not significantly different from the other two groups, and their inclusion as a comparison group masked the real differences between the other two groups. The MMPI results suggest it may be possible to identify a suicide attempt group in substance abusers but not when contrasted with a suicidal ideation group. Treatment implications are considered.     

MCMI differences between alcoholics and cocaine abusers: effect of age, sex, and race.

Samples of alcohol-dependent-only subjects (n = 164), cocaine-dependent-only subjects (n = 63), and subjects dependent on multiple substances, including alcohol and cocaine (n = 103), were administered the Millon Clinical Multiaxial Inventory (MCMI) as part of a routine clinical evaluation. The alcohol-only group was older (M = 38.7 years) and had a higher percentage of White subjects than other groups. The multiple-use (60%) group also had a higher percentage of White subjects than the cocaine only group (38%) and a higher percentage of male subjects (81%) than the alcohol-only group (67%). Although the MCMI characteristics of each diagnostic group paralleled previous findings, few MCMI differences were found after controlling for age, sex, and race effects. The implications of these results for treatment development are discussed.     

Delusions and hallucinations of cocaine abusers and paranoid schizophrenics: a comparative study

We compared delusions and hallucinations of 100 cocaine abusers and 100 paranoid schizophrenic subjects admitted to an East Texas state psychiatric hospital. Subjects in both groups feared that individuals or organized groups might harm them in some way, but delusions of the paranoid schizophrenic subjects were more often bizarre than those of the cocaine abuse subjects. "Cocaine bugs" (parasitosis) were more often found in the cocaine abuse subjects. Command hallucinations were found in both groups, but the commands of the schizophrenic group more often related to harming or killing others. Cocaine abusers had a greater frequency of visual hallucinations (47 to 7), distinguished by shadows, flashing lights ("snow lights"), objects moving and bugs crawling on the arm. Finally, the most distinguishing characteristics were identity delusions, possession delusions, grandiose delusions (other than identities and possessions), and delusions that their families were imposters (Capgras Syndrome) reported by paranoid schizophrenics. No such delusions were reported by the cocaine abusers.     

An MMPI Typology of Cocaine Abusers

Three types were found in a cluster analysis of scores on the Minnesota Multiphasic Personality Inventory (MMPI) of 100 men voluntarily presenting for treatment of cocaine abuse. Type 1 (n = 59) had a mean MMPI profile consistent with the hypothesized grouping of persons who self-medicate with cocaine as a means of overcoming depression. The relatively normal mean MMPI profile obtained by Type 2 (n = 37) suggested little indication of significant psychopathology. Type 3's (n = 4) mean MMPI profile suggested either severe disturbance or profile invalidity. Types were found to differ in the nature of drug use, reactions to cocaine, education level, and social class, but not on the scales of the Adjective Check List.     

An organizational typology for self-help groups

Conclusion Several continuing obstacles have hindered the compilation of a research-based body of literature on self-help groups. Among them are the diversity of the groups and the need for appropriate research methodology. The validated typology described above was designed to address some of these problems. It provides a means of recognizing the diversity of the groups and sorting them into broad types without stating that one is better or more productive than another. It supplies a framework for examining the organizational features of a group in order to facilitate comparison with other groups. It recognizes the potential effects of time, change, and leadership on the small local units of self-help organizations. It has implications for making research more compatible with self-help groups. The use of this typology might eliminate some of the ambiguity and conflicts currently found in the literature and thereby help people — professionals and self-helpers — to more clearly understand the nature and functioning of self-help groups.     

Evaluating the relative effectiveness of three aversion therapies designed to reduce craving among cocaine abusers

Crack cocaine use and dependence has been steadily increasing since the mid‐1980s. Treatment approaches vary from simple psychotherapy to intensive medication regimens. One clear phenomenon that has been implicated in the continued use and abuse of crack cocaine is craving. Craving is believed to be a response that has been conditioned with previous drug using episodes, and is elicited by environmental cues. The current study investigated the use of three aversion therapies (chemical, covert sensitization, and faradic) designed to eliminate craving for cocaine. Seventy subjects were randomly assigned to one of three aversion treatments or a relaxation control condition. Results indicate that aversion therapy reduces crack cocaine craving. The use of aversion therapy as an adjunct to traditional treatment programs for reducing craving is discussed. Copyright © 2004 John Wiley & Sons, Ltd.     

An empirical couple typology based on differentiation

Both spouses of 100 married, heterosexual couples completed the Personal Authority in the Family System Questionnaire (PAFS-Q). A cluster analysis of the couples' scores on the four intimacy and fusion scales of the PAFS-Q produced four clusters that were meaningfully distinct in the patterns of differentiation of the wives and husbands. Couples comprising these clusters are described in terms of intergenerational theories of family interaction.This paper is based on the master's thesis of the first author submitted to the Graduate School of Texas Woman's University. A presentation based on this work was given at the 1988 annual convention of the Southwestern Psychological Association, Tulsa, Oklahoma. The authors thank Glenda Peters and Joe Natale for their contributions to the preparation of this paper. A more extensive report of the methodology and results of this study can be obtained from the second author.     

An MMPI Comparison of Two Groups of Institutionalized Delinquents

Two independent studies compared the MMPI performance of 2 groups of matched institutionalized delinquent boys, those who caused trouble in dormitories (SSs) and those who did not (GGs). In the 1st study, Scale 4 was the only statistically significant scale. Cross-validation found no scales statistically significant. Nineteen items which discriminated between SSs and GGs in the 1st study did not hold up in the cross-validation study. It is concluded that the MMPI has questionable value in discriminating between different levels and types of delinquents.     

MMPI ratings of suicide risk.

Among past attempts to use MMPI data to predict suicidal behavior, there has been a lack of research on the ability of clinicians to identify MMPI profiles of suicidal persons. In this study, the MMPI profiles of 20 male psychiatric patients who committed suicide and the MMPI profiles of 20 male patients who did not attempt or commit suicide were presented to six clinical psychologists with expertise in MMPI interpretation. The clinicians were asked to classify each MMPI profile as coming from a patient who did or did not later commit suicide, and to rate eight variables thought to be relevant to the assessment of suicide risk. Data analysis revealed that the clinicians could not identify suicide and nonsuicide patients from their MMPI profiles. Furthermore, the ratings of the eight suicide variable did not differentiate suicide and nonsuicide patients.     

An empirical classification of non-violent offenders using the MMPI

MMPI protocols of 87 non-violent male offenders were cluster analysed on eight experimental scales. Four clusters emerged. These were compared with the findings from 105 prisoners with convictions for violence. Clusters tended to be similar across the two samples with the exception of the ‘Inhibited’ offender. This non-violent group tended to be less psychiatrically disturbed, as well as less introverted, anxious and hostile than its corresponding violent cluster.     

A typology of family social environments.

A sample of 100 families measured on ten dimensions of their social environments was subjected to cluster analysis to develop an empirically based taxonomy of families. Six distinctive clusters of families were indentified: Expression-Oriented, Structure-Oriented, Independence-Oriented, Achievement-Oriented, Moral/Religious-Oriented and Conflict-Oriented. The clusters showed systematic differences in background characteristics such as size, ethnic minority composition, drinking patterns, and family disturbance and incongruence. Some evidence that certain clusters of families are composed of different sub-clusters was presented. An empirically derived taxonomy of the social environments of families may help to understand how different family environments are linked to different family outcomes.     

Suicide attempts among drug abusers.

The relationship between substance abuse and suicide is indicated by the high rate of attempted suicide among alcoholics and drug abusers as well as the increased likelihood of repeated attempts in these populations. This study reports on the psychological characteristics of male drug suicide attempters who are in treatment for their addiction problem. Data collected from 166 veterans included background information, symptoms, mood, social functioning, and attitude measures. Of the drug abuse patients, 26 percent reported having made a suicide attempt. These subjects were found to be significantly more depressed, angry, insecure, and anxious than the nonsuicide-attempt drug abusers. Treatment staff need to be sensitized to the possibility of repeated suicide attempts among substance abuse patients.
