Using a projective technique among child and adolescent psychiatric inpatients, we tested several hypotheses derived from Coyne's (1976b) interpersonal theory of depression. First, we predicted that depression would be associated with rejection, even controlling for the effects of aggression. Depression and rejection were associated only when aggression effects were covaried. Second, we hypothesized that the depression-rejection relation would display symptom specificity. Consistent with this hypothesis, we found that depression, but not anxiety, was related to rejection. Third, we assessed whether an index of interpersonal style—reliance on others—moderated the depression-rejection relation. Results suggested that depression and overreliance were both associated with high rejection scores, whereas the combination of low depression and low reliance on others was associated with low rejection scores. We found that results held across age groups. The implications of our findings for the interpersonal theory of depression in youngsters are discussed.  相似文献

The correlations and comorbidities of a series of adolescent problem behaviors were studied in a sample of 739 New Zealand 15-year-olds. This analysis revealed the presence of strong comorbidities between different problem behaviors. The data were modeled using methods of unrestricted latent class analysis and this suggested that the best fitting model to describe the data was one which assumed that adolescent problem behaviors were described by four general classes of children. While the same general four-class model applied to males and females, there were marked gender differences in the rates of problems. Specifically, the predominant problem behaviors in females were those relating to an accelerated transition to adulthood marked by early sexual activity, alcohol abuse, and cannabis use whereas the predominant problems for boys were related to antisocial and law-breaking behaviors. Rates of children with no problems (85%) and with multiple problems (3%) were similar for boys and girls.This research was funded by grants from the Health Research Council of New Zealand, the Canterbury Medical Research Foundation, and the National Child Health Research Foundation.  相似文献

Parent-report based scales for the assessment of sex-dimorphic behavior are an important tool in research on psychosexual differentiation and its disorders. This paper presents the factor analysis and corresponding scale development for the slightly expanded Child Game Participation Questionnaire (Bates & Bentler, 1973), based on the parents of a demographically diverse school sample of 355 girls and 333 boys aged 6 to 10 years. Evidence supporting each of three theoretical positions in gender assessment — unidimensional bipolar, two-dimensional unipolar, and multidimensional — was provided. Effect sizes were unusually large for gender, but small for age, socioeconomic level, and race/ethnicity.This research was supported in part by a NICHD postdoctoral fellowship (NRSA HD06726; sponsor: Dr. Meyer-Bahlburg) awarded to Dr. Sandberg, by grants to Dr. Ehrhardt and Dr. Meyer-Bahlburg from the Spencer Foundation, the William T. Grant Foundation, the Ford Foundation, and NIMH (center grant 2-P50-MH43520, Anke A. Ehrhardt, Ph.D., Principal Investigator), and by the NIMH Clinical Research Center grant MH-30906.We thank the children and parents who participated in the study. Dr. Jacob Cohen consulted on statistical matters. Ms. Patricia Connolly provided word processing services. A portion of this work was presented as a poster at the XIth Biennial Meeting of the International Society for the Study of Behavioral Development, Minneapolis, Minnesota, July 3–7, 1991 (Abstracts, p. 285).  相似文献

The four experiments reported here provide evidence that (1) misleading postevent suggestions can impair memory for details in a witnessed event and (2) subjects sometimes remember sug-gested details as things seen in the event itself. All four experiments used recall tests in which subjects were warned of the possibility that the postevent information included misleading sug-gestions and were instructed to report both what they witnessed in the event and what was men-tioned in the postevent narrative. Recall of event details was poorer on misled items than on control items, and subjects sometimes misidentified the sources of their recollections. Our re-sults suggest that these findings are not due to guessing or response biases, but rather reflect genuine memory impairment and source monitoring confusions.  相似文献

Summary Two experiments investigated relative spatial coding in the Simon effect. It was hypothesized that relative spatial coding is carried out with reference to the position of the focus of visual attention. The spatial code for an imperative stimulus presented exactly at the position of focal attention should be neutral on the horizontal plane, and therefore no Simon effect should be observed. However, when the imperative stimulus is presented to the left or to the right of the current position of focal attention, the spatial code should not be neutral, thus producing a Simon effect. In both experiments, focal attention was manipulated either by a peripherally presented onset precue (Experiment 1) or by a centrally presented symbolic precue (Experiment 2). Results showed that the Simon effect was substantially reduced in both experiments when a valid precue preceded the imperative stimulus just in time to conclude refocusing of attention to the position of the imperative stimulus before it was presented. However, conditions with neutral precues yielded a normally sized Simon effect. In both experiments, the Simon effect decreased as the SOA grew when the precue was valid. At least for the Simon effect, the results can be interpreted as evidence that relative spatial coding is functionally related to the position of the focus of attention.  相似文献

This paper describes a format for group intervention with children of parents with AIDS. Therapeutic factors specific to group work with these children and special issues regarding AIDS are discussed. The stages of development of such groups are outlined, with particular attention paid to themes of grief and loss. Suggestions for future work in this area are given.  相似文献

The purpose of this investigation was to assess the influence of White racial identity attitudes on racism. A total of 234 White undergraduate students participated in this investigation. The students completed the White Racial Identity Attitude Scale (Helms & Carter, 1990) and the New Racism Scale (Jacobson, 1985). Consistent with findings in previous research, White racial identity attitudes were predictive of racism. We also found gender and age differences in White racial identity attitudes. Implications of these findings are discussed in terms of the role of counselors in addressing racial awareness on college campuses.  相似文献

The authors discuss the role of an academic department in promoting faculty development. Specifically, the authors (a) define faculty development from a departmental perspective, (b) discuss stages and seasons in academic careers, and (c) delineate specific faculty development goals and programs within the department.  相似文献

The authors examined the association between demographic variables and self-reported multicultural counseling competencies among counselors. A national sample of 220 counselors affiliated with university counseling centers participated in this investigation. Counselors responded to 40 Likert-type statements about multicultural awareness, knowledge, skills, and relationships. Results from a series of multivariate and univariate analyses indicated that Asian American and Hispanic counselors reported more multicultural knowledge than did White counselors, and African American, Asian American, and Hispanic counselors reported more competence in multicultural awareness and relationships than did White counselors. No effects were found for other demographic variables. Implications of these findings are discussed.  相似文献
