The Bristol Social Adjustment Guides (BSAG) are widely employed in research and in the identification of maladjustment in school children. The BSAG provides scores on several indices including five homogeneous behavioral syndromes and one associated grouping. Field experience suggests that maladjusted children frequently manifest problems in more than one syndrome. In order to discover what patterns of syndromic profiles may commonly exist among children, the data for the most recent revision of the BSAG are reanalyzed. The syndrome scores for all 2,527 5- to 15-year-old regular school children in the standardization sample were grouped into similar profile patterns by hierarchical cluster analysis. Sixteen homogeneous syndromic profile types emerged. The resultant profile types were described on the basis of their component behaviors and examined for membership trends by sex and age groups. Multiple syndromic profiles represented 60% of all maladjusted children.The author wishes to thank Dr. Denis H. Stott, former professor of psychology at the University of Guelph, Ontario, for kindly making the Bristol Social Adjustment Guides data available for this study.  相似文献

Completion responses were collected for two sets of sentence contexts, which were designed to produce different distributions of probabilities for the primary responses. The subject population consisted of undergraduate college students. For each context, responses and their respective probability of occurrence are listed, and an index of the primary responses is provided. It is hoped that these normative materials will facilitate comparison among future studies of the effects of sentence contexts on word processing.  相似文献

Two methods of language instruction administered to mentally retarded subjects at the two-word stage of language development were investigated. Subjects of the mimicry training group imitated Agent-Action-Object (AAO) constructions immediately after presentation, while subjects of the imitative modeling group first heard the AAO presentation and later produced the AAO construction in response to a verb question. Imitative modeling subjects achieved as many correct AAO responses during training and more correct responses on a generalization task and in a free play setting. They also displayed more novel response behavior (selective imitations) and spontaneously corrected productions. The results support the use of modeling procedures for inducing language production in the retarded.  相似文献

Individual and organizational correlates of employees who refuse seniority-based promotions in union lines of progression are examined. The sample consisted of 313 production employees of a large manufacturing complex. Correlational and discriminant analyses revealed that age, being female, and number of employees in the department related positively to promotion refusal, while years of education and pay showed a negative relationship. Of these variables, years of education was the strongest predictor. Potential explanations for the results relate to stress avoidance, perceived inabilities, and equity theory. Areas for future research are suggested.  相似文献

The advantages of selecting agoraphobic patients for treatment by group exposure according to their residential geographic neighbourhood were evaluated in terms of facilitation of ‘homework’ practice and increased social contact. Both ‘zoned’ and ‘unzoned’ groups showed gains in ability to perform hierarchy items after 11 sessions of exposure, relative to a no-treatment control group. However only zoned subjects showed significant reductions in experienced anxiety when executing such items. Self-ratings of overall phobic severity also suggested a zoned group was superior to unzoned while assessors' ratings indicated both groups as equally improved. Only zoned subjects showed a significant increase in social range. Improvements were maintained at 3-months follow-up. No effect of treatment was found on either the Zung measure of anxious mood or on social integration.These results suggest that, where practical, zoning might offer the means for desirable continuation of intensive clinic-based group treatment as well as the benefit of extending treatment into the patients' environment as in home-based treatments. Crucial levels of group cohesion might also be increased although therapists should be prepared to negotiate resistance to a socially demanding programme from patients with significant additional social phobias.  相似文献

This survey reports the results of a national survey of training programs in family therapy. Two hundred and forty-five programs responded to the survey questionnaire providing data for the development of a master list of training programs and a general assessment of the nature and magnitude of training efforts in the field. The survey included programs housed in diverse institutional settings. The data indicate the extent of growth and the increasing formalization of professional training in family therapy. A classification system is proposed for distinguishing among the major types of facilities providing family therapy training. Programs are compared in terms of the type, duration, and intensity of the training offered and the number of students enrolled.  相似文献
