There are relatively few community-based epidemiological studies in which correlates of
depressive disorders were identified through multivariate analyses in children and adolescents aged 6--14
years. Moreover, several family characteristics (e.g., parent-child relationship) have never been explored in
this regard. The purpose of this study was twofold. Using data from the Quebec Child Mental Health Survey,
it sought: (1) to identify psychosocial correlates associated with depressive disorder in two age-groups (6--11 and 12-14
years) according to informant (child/adolescent, parent); and (2) to interpret the relative
importance of correlates by ranking variables according to strength and consistency of association across
age-groups. Logistic regression models show correlates to be inconsistent across informants. The ranking of
correlates indicates a major contribution of only-child status/ordinal position, parent's major depressive
disorder, stressful family events, and parent-child relationship, thereby supporting the hypothesis of the
relevance of family context in the development of depression. 相似文献

This research investigates the hypothesis that the mere suggestion of sexism can harm women’s experience of an instruction situation. Across three experiments, women exposed to the suggestion about the sexism of a male instructor reported a less positive experience, performed worse on a logic test, and rated the instructor as less competent than did women who were not exposed to the suggestion. The same harmful consequences did not befall men, even when they were potential targets of the alleged sexism. To interpret results, the authors emphasize the concept of social identity threat: the concern that one will be the target not only of stereotypes about inferiority, but also a more general hostility based on a salient social identity. Results suggest the need to expand conceptions of discrimination to include systemic forms of identity threat that can be sufficient to produce harm, even in situations where differential treatment is initially absent. 相似文献

Speeding is a preventable risky behavior that contributes to risk of accident. Readiness to change reflects an individual's recognition of and desire to change behavior. No measure to identify readiness to change has yet been validated for speeding. The Readiness to Change Questionnaire appraises readiness to change drinking behavior. The questionnaire was adapted to speeding and its psychometric properties examined. Participants (N = 112) completed the questionnaire and reported their usual driving speed. A clear component structure and acceptable internal consistency and test-retest reliability were found. Convergent validity was indicated by an association between higher readiness to change and lower driving speed. Results support the questionnaire's potential as a measure of readiness to change speeding, and advance research into the role of motivation in speeding behavior. 相似文献

Brown and Jeeves (1993) found that an evoked potential estimate of interhemispheric transfer time, from the left to the right hemisphere, correlated negatively with a bilateral field advantage (BFA) in a response-choice letter matching task. We implemented a go no-go dot size matching task to determine whether the crossed-uncrossed difference (CUD) in reaction time, commission errors and omission errors (estimates of the “cost” of interhemispheric transfer) would correlate with BFAs in data from the same experiment and whether the type of decision (“same” versus “different”) would modulate the CUDs and/or BFAs. Sixteen normal right-handed subjects were tested. The CUDs were negatively correlated with the BFAs. Canonical correlation analysis of this set of relations was highly significant (r= .95). Estimates of left-to-right relay were far more strongly related to BFA (p= .0001) than were estimates of right-to-left relay (p= .03). “Same” decisions yielded a unilateral field advantage and “different” decisions a bilateral field advantage in omission error data, this crossed interaction reaching significance. More efficient interhemispheric relay favored BFAs, i.e., strongly suggesting in such cases an advantage of interhemispheric over intrahemispheric integration. This effect appeared to be markedly asymmetric. Furthermore, resource sharing within and between the hemispheres was a function of the “same” versus “different” dimensions of the decision to be made, especially in omission errors. The opposite dissociation occurred less markedly in the reaction times, this double dissociation reaching significance, revealing presence of a subtle speed–accuracy trade-off in interhemispheric dynamics. 相似文献
