In this pilot study, we examined the relationship between health factors, sociodemographic factors, and body mass index (BMI) across two generations (n = 41 parent-child pairs). Generation 1 study variables included parent- and family-focused characteristics and health variables, the Generation 2 variables included child demographic factors, and the outcome variable was youths’ physical health (operationalized as BMI). Regression models revealed that Generation 1 variables, taken together, accounted for 26% of the variance in youth BMI. However, only the parent’s mental health symptoms (i.e., depression symptoms) made a unique contribution to the variance in youth BMI. Logistic regression analysis revealed that the youths’ race and age—but no other demographic factor—were significantly related to youth BMI-for-age. Our findings suggest that youth race, age, and parent mental health are each associated with youth physical health (i.e., BMI), confirming previous study findings that parental factors and demographic factors should be considered when exploring youth health outcomes.  相似文献

The present studies examined the extent to which (a) communalism, familism, and filial piety would pattern onto a single family/relationship primacy construct; (b) this construct would be closely related to indices of collectivism; and (c) this construct would be related to positive psychosocial functioning and psychological distress. In Study 1, 1,773 students from nine colleges and universities around the United States completed measures of communalism, familism, and filial piety, as well as of individualistic and collectivistic values. Results indicated that communalism, familism, and filial piety clustered onto a single factor. This factor, to which we refer as family/relationship primacy, was closely and positively related to collectivism but only weakly and positively related to individualism and independence. In Study 2, 10,491 students from 30 colleges and universities in 20 U.S. states completed measures of communalism, familism, and filial piety, as well as of positive psychosocial functioning and psychological distress. The family/relationship primacy factor again emerged and was positively associated with both positive psychosocial functioning and psychological distress. Clinical implications and future directions for the study of cultural values are discussed.  相似文献

Perceived sex appropriateness of the work situation is believed to constrain work opportunities, particularly for women. However, sex appropriateness may be defined either with respect to the entire job or with respect to the tasks which comprise the job. In this study sex appropriateness of job tasks was examined by obtaining subjective estimates of the masculinity-femininity of the job requirement dimensions defined by the Dictionary of Occupational Titles (DOT). Results indicate that interacting with things is perceived as masculine, interacting with people is perceived as feminine, and interacting with data is perceived as falling between the other two. There is less agreement on the masculinity-femininity of specific types of interactions with data, people, and things. Sex appropriateness of specific requirements was found to be only moderately associated with the DOT's assessment of the complexity of those requirements. Further, sex appropriateness of job requirements was not highly related to the job sextypes established by Shinar (Shinar, E. H. Journal of Vocational Behavior, 1975, 7, 99–110) and Krefting et al. (Krefting, L. A., Berger, P. K., and Wallace, M. J. Jr. Journal of Vocational Behavior, 1978, 13, 181–191). This suggests that sex appropriateness of a job and sex appropriateness of the tasks which comprise the job are distinct, separate concepts.  相似文献

The relationship between gender role and person-perception accuracy was examined in this research. Young adults who were masculine, feminine, androgynous, or undifferentiated in their gender role interacted with a child, and with a peer, in role-playing situations that focused on parenting and marital behaviors. The accuracy with which subjects predicted the child's perception of them, and the accuracy with which they perceived the interpersonal traits of the peer, were assessed. The results indicated that androgynous subjects were clearly superior in predicting the child's perceptions of them, but were no better than the other gender-role groups in terms of peer perceptions. Rather, females were more accurate than males in perceptions of gender-related traits. Implications of this research for the relationship between gender role and parenting behavior, and directions for future research that examines person-perception accuracy, are discussed.  相似文献

Abstract

One important emotion theory currently postulates an innate tie between specific infant facial expressions and a set of discrete basic emotions. The arguments and evidence relevant to this assertion are reviewed. New data are presented from a naturalistic study of one infant's early expressive development and a judgement study of infant facial, vocal, and body activity. These data challenge the innate tie hypothesis. Based on dynamical systems systems theory, an alternate conceptual framework is presented that may allow us to usefully retain the concept of basic emotions while accommodating the data on infant expressive development.  相似文献
