MMPI-2 and MCMI-III scores among dutch inpatient substance abusers: Assessing correspondence and cross-cultural equivalence

The Millon Clinical Multiaxial Inventory (MCMI-II and MCMI-III) and the Minnesota Multiphasic Personality Inventory (MMPI-2) were applied to 263 Dutch inpatient substance abusers with multiple psychiatric diagnoses, and the results compared with those of 306 North-American substance abusers studied by Ward (1995). We looked for structural similarity both across groups (per instrument) and across the two instruments (per sample), using principal components analysis and congruence analysis. The component structure found by Ward was partly replicated in the Dutch group, thus cross-validating the use of the two instruments with these patients. Moreover, as found by Ward, the MMPI-2 content and supplementary scales of the Dutch sample proved to be important determinants of the first three MMPI-2 components, adding to convergent validity. Questions remained about the influence of the (dis)continuity of MCMI-II and MCMI-III on the replicability of the MCMI components.     

Emil Kraepelin's dream speech: A psychoanalytic interpretation

Freud's contemporary fellow psychiatrist Emil Kraepelin collected over the course of several decades some 700 specimens of speech in dreams, mostly his own, along with various concomitant data. These generally exhibit far more obvious primary-process influence than do the dream speech specimens found in Freud's corpus; but Kraepelin eschewed any depth-psychology interpretation. In this paper the authors first explore the respective orientations of Freud and Kraepelin to mind and brain, and normal and pathological phenomena, particularly as these relate to speech and dreaming. They then proceed, with the help of biographical sources, to analyze a selection of Kraepelin's deviant dream speech in the manner that was pioneered by Freud, most notably in his 'Autodidasker' dream. They find that Kraepelin's particular concern with the preservation of his rather uncommon family name-and with the preservation of his medical nomenclature, which lent prestige to that name-appears to provide a key link in a chain of associations for elucidating his dream speech specimens. They further suggest, more generally, that one's proper name, as a minimal characteristic of the ego during sleep, may prove to be a key in interpreting the dream speech of others as well.     

Effects of nutritional supplements on aggression,rule‐breaking,and psychopathology among young adult prisoners

Objective: In an earlier study, improvement of dietary status with food supplements led to a reduction in antisocial behavior among prisoners. Based on these earlier findings, a study of the effects of food supplements on aggression, rule‐breaking, and psychopathology was conducted among young Dutch prisoners. Methods: Two hundred and twenty‐one young adult prisoners (mean age=21.0, range 18–25 years) received nutritional supplements containing vitamins, minerals, and essential fatty acids or placebos, over a period of 1–3 months. Results: As in the earlier (British) study, reported incidents were significantly reduced (P=.017, one‐tailed) in the active condition (n=115), as compared with placebo (n=106). Other assessments, however, revealed no significant reductions in aggressiveness or psychiatric symptoms. Conclusion: As the incidents reported concerned aggressive and rule‐breaking behavior as observed by the prison staff, the results are considered to be promising. However, as no significant improvements were found in a number of other (self‐reported) outcome measures, the results should be interpreted with caution. Aggr.

Assessment of hostility in patients with coronary heart disease

One of the problems in efforts to more clearly conceptualize hostility is the amount of method variance, which ranges from self-report techniques to interview-based methods and mirrors the multidimensional nature of hostility and related constructs. In addition, rather few studies concerned with the assessment of hostility have specifically used samples of coronary heart disease (CHD) patients. The purpose of this study was, therefore, to examine the multidimensionality of the construct of hostility in a sample of male coronary patients with some frequently used instruments. Factor analysis was used to detect the relevant underlying constructs, which were assessed using a variety of hostility measures in a sample of cardiac patients undergoing baseline assessment in an ongoing health-education intervention study. Measurement included both questionnaires and interviews. Participants (N = 235) were divided into 3 diagnostic groups: patients who had recently undergone (a) a myocardial infarction, (b) coronary artery bypass grafting, or (c) percutaneous transluminal coronary angioplasty. A 4-factor solution appeared to provide the best fit, and the following factors were isolated: Anger-Out, Negative Affect, Coping, and Anger-In. All intercorrelations were less than .50. Medical diagnosis did not differ with regard to the 4 factors found. The total hostility construct as measured by the structured interview (SI) did not fit into the 4-factor model. This study was the first to show that dimensions of anger and hostility constitute valid and relevant aspects of the general construct of hostility for a representative group of CHD patients. The 4 aspects of hostility isolated using some well-known hostility questionnaires and the SI explained most of the observed variance. Although the SI appeared to tap more general state anger, the 4 aspects of hostility may be differentially related to health in those who are coronary prone. Future studies on the role of hostile or negative emotions in CHD patients should, therefore, pay greater attention to the multidimensional nature of hostility and may clearly benefit from the use of the 4-factor model described in this article.     

Personality disorders, depression, and coping styles in Argentinean bulimic patients

This study investigates the coping styles of bulimic patients with personality disorders (PDs) and the effects of the level of depression on the relations between PDs and coping. The sample consisted of 75 Argentinean bulimic outpatients engaged in treatment. Patients completed the SCID II (Structural Interview for DSM IV-Personality Disorders), COPE (Coping Inventory), and the SCL-90-R (Symptom Checklist-90-Revised). No differences in the coping styles of bulimic patients with or without a PD were found. However, when three specific PDs were considered-Avoidant, Obsessive-Compulsive, or Borderline PDs-clear differences in the coping styles of the bulimics were found. However, the differences disappeared when depression was controlled. Regarding the severity of the three specific PDs, coping styles were only found to be associated with the Avoidant PD. Depression showed to affect the relations between coping styles and two specific PDs-Avoidant and Borderline PDs-in bulimic patients.     

Memory consolidation for the discrimination of frequency-modulated tones in mongolian gerbils is sensitive to protein-synthesis inhibitors applied to the auditory cortex

Differential conditioning of Mongolian gerbils to linearly frequency-modulated tones (FM) has recently received experimental attention. In the study of the role of cerebral protein synthesis for FM discrimination memory, gerbils received post-training bilateral injections of anisomycin into the auditory cortex under light halothane anesthesia. Compared with saline-treated controls, anisomycin-treated gerbils showed a discrimination decrement during the subsequent three days of training. They markedly improved their performance within training sessions, but started each session at low levels. When repeatedly trained gerbils received post-session injections of anisomycin, discrimination performance during subsequent sessions was similar to the pre-injection performance, indicating that retention, retrieval, reconsolidation, and expression of the established reaction were not affected. However, the improvement of a partially established discrimination reaction was impaired after this treatment. Intracortical injections of emetine confirmed this finding. Neither drug affected FM discrimination learning when given several days before the initial training. Our results suggest that protein-synthesis inhibitors applied to the auditory cortex of gerbils during the post-acquisition phase interfered with learning and memory-related aspects of FM processing. The resulting deficit was evident for a number of post-injection training days. This effect was probably due to impaired consolidation, i.e., processes required for long-term stabilization or retrieval of the memory trace while leaving short-term memory intact.     

Cross-cultural replication of the five-factor model and comparison of the NEO-PI-R and MMPI-2 PSY-5 scales in a Dutch psychiatric sample

The authors investigated cross-cultural replicability of the five-factor model (FFM) of personality as represented by the revised NEO Personality Inventory (NEO-PI-R; P. T. Costa & R. R. McCrae, 1992) in a sample of 423 Dutch psychiatric patients. Also, NEO-PI-R domain scales were compared with the Personality Psychopathology Five (PSY-5; A. R. Harkness & J. L. McNulty, 1994) scales of the Minnesota Multiphasic Personality Inventory-2 (J. N. Butcher, W. G. Dahlstrom, J. R. Graham, A. Tellegen, & B. Kaemmer, 2002). Principal-components analysis with procrustean rotation confirmed the hypothesized structural similarity of the present sample with the U.S. normative factor scores. All of the hypothesized relations between NEO-PI-R and PSY-5 scales were confirmed. The results provide evidence for cross-cultural replicability of the FFM and for validity of the NEO-PI-R and PSY-5 constructs in the psychological assessment of psychiatric patients.
