Validity of the Threat Index.

The validity of the Threat Index was examined in a study of 42 students and 15 HIV+ clients. When completing the Threat Index, subjects rate the self and death on 30 bipolar adjectives. A count is made of the number of times the same adjective poles are used to describe the self and death. Uses of the same poles are called matches, while uses of different poles are called splits. The Threat Index is based on the assumption that splits indicate threat. Analysis showed that neither splits nor matches were usually threatening and that neither was necessary or sufficient for the experience of threat. These results did not support the validity of the Threat Index.     

Black South Africans and Canadians on neuroticism as a dimension of personality.

This study was done to assess gender and cultural differences on neuroticism as a dimension of personality among both Canadians and Black South Africans. No statistically significant cross-cultural differences were observed. However, statistically significant gender differences emerged among both Canadian and African men and women, with the latter scoring higher on neuroticism than the former.     

Premenstrual symptoms: the role of irrational thinking.

104 women, between the ages of 18 and 45 years, were surveyed to investigate the relationship between premenstrual symptomatology, as measured by the Modified Menstrual Distress Questionnaire, and irrational thinking, as measured by the General Attitude and Belief Scale. The women who reported greater premenstrual symptomatology also reported significantly higher scores in the "need for comfort" irrationality subscale. This indicated that these women had particular difficulty dealing with hassles and the resulting feelings of tension and irritability in the premenstruum. It was suggested that the absence of significant effects for other rationality-irrationality subscales could be associated with testing at different times during the menstrual cycle. Irrationality, like other conditions (such as anxiety and depression) prevalent in the premenstruum, could change in intensity across phases of the menstrual cycle.     

Depression, suicide ideation, and aggression among high school students whose parents are divorced and use alcohol at home.

106 high school students from a small rural high school completed the Children of Alcoholics Scale, Zaks and Walters' Aggression Scale, Beck Depression Scale, and a modified version of the Beck Scale of Suicide Ideation. Analyses of variance showed boys were not experiencing suicide ideation any more than girls; suicide ideation was similar across the four grades, but on aggression alcohol-dependent boys scored significantly higher than girls, and in Grade 9 boys' scores were significantly higher than those in Grade 10. The sophomores' scores on alcohol dependency were significantly lower than the freshmen's scores. Boys and children from divorced homes had higher scores on aggression than girls and children from nondivorced homes. Children from homes in which alcohol was used had higher depression scores than children from nonalcoholic homes. Freshman girls and sophomore boys had higher depression scores than senior boys and girls. A Pearson r of 0.28 between scores on alcohol dependency and suicide ideation was significant, but research is needed to understand better the associations of thoughts of suicide and drug-alcohol dependency among these high school students so strategies for prevention and intervention can be focused.     

Correlations of Beck Depression Inventory and Reynolds Adolescent Depression Scale.

The scores of 15 adolescents who had a primary diagnosis of Posttraumatic Stress Disorder, 21 of Conduct Disorder, and 23 control subjects on the Beck and Reynolds depression scales were correlated .58 over-all, .73 for the Posttraumatic group, .48 for the Conduct Disordered group, but .37 for controls. The Reynolds scale did not identify depression in these adolescents as effectively as did the Beck scale.     

Gilles de la Tourette syndrome in India: two cases.

Two cases of Gilles de la Tourette syndrome from India are presented. The symptomatology of Tourette syndrome is the same as that documented in western populations which suggests biological factors in the aetiology of the syndrome.     

Validity and clinical scale comparisons between the MMPI and MMPI-2 with psychiatric inpatients.

This study was designed to investigate the comparability of the original MMPI (1950) and the MMPI-2 (1989) with a psychiatric patient population. 34 male and 3 female patients, shortly after admission to one of two acute psychiatry units, completed the old and revised versions of the MMPI. Paired t tests indicated but scant differences for raw scores, while many more differences were found among T scores for validity, clinical, and supplemental scales. Analyses, however, showed all scales on the two forms to be highly correlated. Analysis of the high-point and two-point codes across the two administrations also showed relative stability, although the proportion of Scales 2 (Depression) and 8 (Schizophrenia) decreased, while those for Scales 6 (Paranoia) and 7 (Psychasthenia) increased markedly in the MMPI-2 protocols. Examination of each version's discriminability among mood- and thought-disordered subsamples suggested that the MMPI provides slightly better delineation between diagnostic classes. Discriminant function analyses showed that there were essentially no differences between the two forms in the accurate classification of clinical and nonclinical groups. The findings reported here provide support for the MMPI-2; despite modification, the newer form retains the advantages of the original MMPI. Differences found here may be unique to psychiatric patients and their patterns of MMPI/MMPI-2 equivalence and may not generalize to other special populations.     

Reliability and validity of the Cognitive Slippage Scale in two populations.

Analyses of responses from a clinical sample of 120 patients (primarily schizophrenics) and from 158 college students to the Cognitive Slippage Scale, a scale designed by Miers and Raulin to identify speech deficits and confused thinking in schizophrenic and schizotypal personality disorders showed high internal reliability; Cronbach's coefficients alpha were .89 and .86 in the clinical and college student samples, respectively. The mean scale scores significantly differentiated the two samples. Also, change scores over 4 wk. showed adequate stability for both samples. Item analysis indicated Items 11, 20, 21, and 28 may not reliably discriminate between schizophrenic and college student samples. Over-all, these preliminary results are consistent with the reliability and validity of the scale.     

Sensory and affective components of pain: separation and synthesis.

It has become increasingly accepted that pain is not simply a sensation generated by nociceptors, but a perceptual phenomenon with particular emotional qualities. The purpose of this article is to bring together vastly different streams of research on the divisibility of pain into sensory and affective components. Empirical evidence for this divisibility is drawn from recent studies using multivariate statistics, signal detection theory, and unidimensional scaling. An important conclusion is that separable though pain components may be, they are not necessarily independent. In critiquing previous research, new criteria are derived for partitioning pain into sensory and affective components. Finally, speculations are offered as to how these same components might be synthesized on the basis of theories of perceptual organization.
