The Rosenberg Self-esteem Scale was administered to 550 14- and 16-yr.-old (+/- 6 mo.) girls. Self-esteem scores were categorized by weight and weight by height. Scores on the Quetelet Index for obesity were correlated with self-esteem scores. Mean self-esteem of the low- and middle-weight by height group was significantly higher than the mean of the high-weight by height group. In analyzing weight alone, the self-esteem of the middle-weight group was significantly higher than the self-esteem of the high-weight group. The correlation of the obesity index and self-esteem indicated that as weight increased self-esteem decreased. 相似文献

Observations on three children with neurolisteriosis (one case of meningitis, two cases of meningoencephalitis, each Serovar 4 b), show that even after the neonatal period, listeriosis must not be ignored in the process of diagnosis and therapy. It is the bacteriological examination of the cerebrospinal fluid, together with the blood culture, and not clinical symptoms and serology that guarantee a timely diagnosis and therapy (ampicillin and gentamicin). 相似文献

From a random sample of 49 patients suffering from torticollis spasmodicus and dependence on alcohol or medicaments, 6 have been selected and are discussed with i view to findings possible mutual influences between the disorders. In particular, premorbid accentuation of personality presented itself as a potential risk factor leading to both tortocollis and alcoholism. In various cases, the patient makes use of alcohol for self-treatment of extrapyramidal-motor symptoms. But such phenomenological developments are preceded by varied constellations of conditions, that have to be taken into account in the treatment. 相似文献

The constituents of the complex affective experience of envy are delineated, and defenses against each of these constituents are explored. Attention is then called to a common, variably adaptive, and socially approved means of obviating or coping with envious feelings, involving a partial identification and culminating in the conscious experience of "being proud of." A conjecture is made regarding the kind of pathology most likely to interfere with this mechanism. 相似文献

Insight reflects the unitary nature of psychic activity in contrast to the fragmentation created in abstracting categories for the purpose of study and discussion. The unique analytic clinical dyad offers a structure in which intrapsychic fragments can be actualized and integrated. As a result, the analyst's contribution is more crucially one of exploration than of revelation. Whatever the area of examination, past or present, the link to analytic immediacy offers the opportunity to make meanings meaningful, to convert known facts to psychic truths. The analyst's clinical task requires his private self-analysis as part of the collaborative exploration of how the patient's mind works. Higher level ego functioning, including acutely active remembering, is at times transiently loosened in order for the analyst to share in the clinical work of discovery. The words the analyst uses to communicate his understanding convey only approximate manifest meanings, though they structurally reveal deeper messages of importance to the patient. These verbal approximations help stimulate self-reflection in the analysand as a step in the process of gaining insight. 相似文献
