The use of computer based diagnostic decision and artificial intelligence are discussed in relation to the problems of validity and reliability of psychiatric diagnoses. The authors suggest a definition of a computer aided classificator as an existent decision system for an automatically analysis of findings. 相似文献

This paper explores the significance of Marie Bonaparte's book, Topsy: The Story of a Golden Haired Chow. The manifest importance of Topsy has been attached to the fact that the Freuds translated it out of gratitude to Bonaparte and because of their love for dogs. Another level of significance emerges when the book is placed in historical context. Topsy elucidates the relationships between Marie Bonaparte, Sigmund Freud, and Anna Freud. It reflects Bonaparte's feelings about Freud's illness and is part of an ongoing dialogue with him. The persistent misplaced emphasis on the "dog story" has obscured the more profound issues. The author suggests that the conflicting needs to appreciate transience and to avoid mourning may account for both the importance of the book and for its obscurity. 相似文献

An investigation into the diagnostic value of psychometric methods for the diagnosis of depressive states involved five psychometric questionnaires, one concentration test procedure, and one problem-solving approach to register cognitive processes. The data obtained for 80 depressive patients of varied aetiology were compared with those of sample of 80 neurotics without depressive aberration. Even univariate comparisons revealed statistically significant differences between the two samples. Multivariate methods (factor analysis, discriminative analysis) yielded more differentiated information. The "Scale for depression depth measurements" was found to be of particular diagnostic relevance; it was standardized for the time being. 相似文献

In this study we investigated the immediate and continued impact on women of a major stressful event, the outcome of pregnancy, and the mitigating effect of self-esteem and intimacy with their spouse on their reactions. Few other studies have investigated initial reactions to crisis events. Ninety-nine Israeli women who experienced either normal delivery or pregnancy complications were interviewed at the time of the event and 3 months later. High self-esteem was found to limit feelings of depression at both times. Intimacy with spouse limited depression at the event, but not at follow-up. High self-esteem was seen as always being exploitable by women who possessed it, whereas the benefit of intimacy with spouse was seen as being dependent on situational demands and environmental constraints. Cross-cultural implications were presented. 相似文献

Two studies are reported on a new Anger Control Inventory based on a cognitive-behavioral person-situation interaction model. In Study 1, the inventory responses of 118 clinical subjects and 190 normal subjects were correlated with an anger problem criterion based on observable signs. Factor analyses were conducted to clarify the construct base of the inventory. In Study 2, comparisons were made between the inventory responses of 100 spouse batterers and 96 normal subjects. Significant differences between the pretreatment and posttreatment scores of 65 batterers given treatment in anger control were obtained on the inventory scales, which were found to be correlated with the problem criterion and discriminating between the clinical and normal groups. The construct validity and clinical utility of the Anger Control Inventory are discussed. 相似文献

The purpose of this study was to explore differences in body satisfaction among female adolescents 14 to 18 years of age. Principal components analysis of a body cathexis measure completed by 751 high school cheerleaders indicated that six factors defined the adolescents' attitudes toward their bodies: satisfaction with the midsection and overall appearance, peripheral body parts, hair and face, mouth, hands, and height. An Age X Body Satisfaction multivariate analysis of variance (MANOVA) was conducted; a Bonferroni adjusted alpha of .007 was established for subsequent ANOVAs. Satisfaction with the mouth increased significantly as age increased, and a similar but nonsignificant trend was found for peripheral body parts. The findings contradict previous research reporting no age differences in the body satisfaction of adolescents. Role demands and physical maturation of the cheerleaders may explain differences based on age. 相似文献

The Threat Index and the Death Anxiety Scale were administered to 228 subjects. Based on the high/low criterion scores, 105 subjects were assigned to the following four groups: (a) high death threat/high death anxiety, (b) high death threat/low death anxiety, (c) low death threat/high death anxiety, and (d) low death threat/low death anxiety. During the experimental phase of the study, subjects viewed a filmstrip on death rituals in various cultures. A recall test was then administered. Results indicated no significant group differences on recall performance. Initial no-show rates for the second part of the experiment were observed in the four groups reflecting a significant negative relationship between death anxiety and initial no-show rates. The possibility of defensive responding on the Death Anxiety Scale was suggested. 相似文献
