Relationship between MCMI-II scales and normal personality traits.

We correlated MCMI-II and 16 PF profiles of 145 couples in outpatient marital therapy and noted significant associations between these tests that were consistently and logically related to constructs which underlie the meaning of the MCMI-II scales. This provided good concurrent validity for both the Personality and Clinical Scales of the MCMI-II. These results add credence to research designed to study Millon's basic styles in normal populations.

Vitamins and carcinogenesis: an overview.

The pathophysiology of carcinogenesis as a multistage process has been reviewed and the rationale for the action of vitamins and biofactors has been presented. This overview will now be followed by presentations of the actions of retinoids, carotenoids, vitamin D and marine natural products by other members of this Symposium.

Relationship between Wechsler scales and Peabody Picture Vocabulary Test-Revised scores among disability applicants.

Relationships, including age, race, gender, and IQ level, between the Wechsler intelligence scales (WISC-R, WAIS-R) and the Peabody Picture Vocabulary Test-Revised (PPVT-R) were studied among 206 applicants for disability benefits in a private practice setting. We found that the PPVT-R seriously underestimated WISC-R IQs by an average of 5 points and WAIS-R IQs by an average of 12 points. Results were discussed in terms of psychometric findings and clinical application. The study demonstrates that psychologists in private practice settings can use the product of their daily work to address important questions that require empirical answers, which, in turn, can influence clinical practice.

MCMI comparisons of cocaine abusers and heroin addicts.

Cocaine addicts (N = 107) and opiate addicts (N = 86) in treatment for drug abuse were compared on the MCMI. Univariate analyses revealed that cocaine abusers showed more traits of the antisocial personality style, whereas heroin addicts evinced more problems with anxiety and somatic distress, probably related to residual problems of withdrawal, and alcohol abuse. Multivariate analyses revealed four distinct clusters (MCMI patterns 456', 865', 56', and 8') that aligned by underlying personality style and clinical syndrome expression rather than by drug of choice. Ideographic analyses further demonstrated consistencies in prevalence rates of DSM-III-R personality disorders. Results do not support the pharmacodynamic theory of drug abuse. It was concluded that the similarities in personality between these two groups are greater than their differences.

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.

Clinical teaching in physical therapy: student and teacher perceptions.

Many practicing physical therapists participate in the most crucial phase of a student's education by serving as Clinical Instructors. The purposes of this study were to identify the clinical teaching behaviors perceived as most effective and most hindering by students and CIs and to compare the response rates of students in bachelor's and master's degree programs. A published 58-item questionnaire was completed by 172 participants from eight physical therapy education programs. The results were analyzed by multivariate analysis of variance. The perceived most helpful teaching behaviors pertained to providing information through feedback. The perceived most hindering behaviors were intimidating questioning and correcting student errors in the presence of patients. The different student and CI ratings for the item "leaves student alone until asked to supervise" has important ethical and educational implications. Master's and bachelor's degree students' ratings differed significantly on four teaching behaviors. Different instructional methods might be necessary for educating these students.

Behavior

Allied health perceptions of effective clinical instruction.

Clinical instruction is a critical component of allied health education. The purposes of this study were to identify those behaviors of clinical instructors perceived as both most effective and most hindering in facilitating learning, to identify and compare the behaviors of clinical instructors as perceived by two different allied health groups, and to categorize into meaningful domains the behaviors identified. A published 58-item questionnaire was completed by 311 clinical students and instructors from eight physical therapy and ten physician assistant programs. Results were analyzed by multivariate analysis of variance. Instructor behaviors rated as most helpful in learning included answering questions clearly, taking time for discussion and questions, and providing opportunities for practicing skills. Behaviors most hindering to learning were asking questions in an intimidating manner and correcting student errors in front of patients. Ratings were significantly different (P less than or equal to .001) between the physical therapy and physician assistant groups on 13 items, and posed important considerations for allied health educators.

A critique of the report of the National Institutes of Health Expert Panel on detection, evaluation, and treatment of high blood cholesterol.

In summary, I think the National Cholesterol Education Program could be strengthened if more realistic values for normal and abnormal serum cholesterol levels were adopted, if lipoprotein typing were recommended as an early step in the screening process, if modification of other risk factors were attempted, and if intervention with diet were avoided for persons without other risk factors whose cholesterol levels are below 6.21 mmol/L. A more flexible program of diet therapy should be offered to those persons with serum cholesterol values over 6.21 mmol/L, which should include not only the "prudent diet" but also other dietary regimens with proven benefits. All physicians should make an attempt to carry out this program of preventive cardiology as a long-term clinical investigation to determine the extent to which modification of serum lipid levels in large outpatient populations influences the prognosis for CHD.

Differences in psychological need hierarchies between black and white drug addicts.

A total of 109 Black and White heroin and cocaine addicts in treatment for drug abuse were compared on the Adjective Checklist (ACL). We found that the White addict had a significantly different pattern of needs than did the Black addict, characterized by more psychological dependence, distress, and maladjustment. Consistent with the MMPI literature in this area, the ACL provides an accurate evaluation of personality dimensions among drug addicts, and White addicts are more psychologically maladjusted than Black addicts.

Amino acid-restricted diets in the treatment of mammary adenocarcinoma in mice.

The effect of a diet moderately restricted in tryptophan on the tumor and the nutritional status of C3H mice bearing mammary adenocarcinoma was examined. Five groups of female tumor-bearing mice were fed ad libitum a diet containing 1) 15% casein, 2) 15% amino acid mixture, 3) 15% amino acid mixture restricted in tryptophan 4) 15% zein supplemented with lysine and tryptophan or 5) 15% zein supplemented with lysine and restricted in tryptophan. Another group of tumor-free mice of similar age fed 15% casein served as a control for the tumor-bearing group fed the 15% casein diet. Moderate restriction of tryptophan in the diet appeared to have no effect on the tumor status of the animal. Tumor burden usually induced malnutrition in the animal. However, tryptophan restriction did not further aggravate this malnutrition. The source of protein, whether casein, amino acid mixture or zein, appeared to make a difference in nutritional status of tumor-bearing animals though not in tumor status. Casein-fed animals generally tended to have higher values for all the nutritional markers studied than did animals fed the amino acid mixture or zein.

Differences in psychological need hierarchy between program completers and dropouts from a drug abuse treatment program.

Psychological need patterns among 116 drug addicts in treatment were measured with the Adjective Checklist. Compared to program completers, program dropouts had higher needs for autonomy and aggression and lower needs for deference, nurturance, and affiliation. This personality style may form the basis of dropping out, among certain types of addicts in certain types of programs, when faced with situational, environmental, or interactional stress. Results also suggest that we may be able to identify a personality pattern at risk for premature termination before the person experiences the impulse to leave.

Differences in psychological needs among drug abusers: first admissions compared to recidivists.

A group of 58 recidivists were compared with a group of 58 first-admission patients in drug abuse treatment, using the Adjective Checklist measuring basic psychological needs. Compared to the recidivists, the first-admission patients scored significantly higher in the needs for Exhibition, Autonomy, Aggression, and Change. A Personality composite for this need configuration was described, and the clinical implications of these results emphasized the need to give attention to the special needs of the patient who is in drug abuse treatment for the first time.
