Although peers' and teachers' evaluations of children's prosocial behavior and peers' sociometric ratings frequently have been used in studies of social development, the validity of young children's ratings of others has been questioned, as has that for teachers' ratings of prosocial behavior. In this study, preschoolers' ratings of peers' sociometric status and prosocial behavior, as well as teachers' ratings of children's prosocial dispositions, were obtained. These were correlated with children's naturally occurring prosocial or social behavior; ratings of prosocial behavior also were correlated with children's prosocial moral reasoning and prosocial self-attributions. Peers' sociometric ratings were positively related to children's sociability whereas prosocial ratings were related to helping (but not sharing) behavior. Teachers' ratings of prosocial behavior were not related to frequency of prosocial behaviors, but were positively related to developmentally mature moral judgments and self-reported motives.  相似文献

This binational study explored the need importance patterns and involvement in work and family contexts. Results reveal that in the work context, growth needs are most important, followed by affiliative and subsistence needs. In the family context, affiliative needs are most important, followed by subsistence and growth needs. Involvement in work and family contexts was found to be influenced by the need satisfaction potential of the respective contexts. This explained the nature of relationship between work and family involvement. The cross-national generalizability and usefulness of a motivational model for research on involvement in multilife-spheres are discussed.  相似文献

The Family System Functioning (FSF) scale is a new instrument for measuring dimensions of the intrafamilial environment thought to be important in recovery from major psychiatric illness. Modest statistical correlations were obtained when FSF ratings of laboratory-based family interactions were compared with researcher-guided therapist ratings of FSF based upon the family's behavior in family therapy sessions during the subsequent month. The data from these two settings provide support for the validity of some of the scales. Because of the modest size of the correlations, however, behavior in the laboratory setting may not always be an accurate indicator of how the family will behave in the early weeks of family therapy.  相似文献

A paper in the American Journal of Community Psychology (AJCP), by Reinke, Holmes, and myself, reported the results of a study of the influence of a friendly visitor program on the cognitive functioning and morale of elderly individuals. The program was reported to have had a significant multivariate effect on a combination of cognitive and morale measures and significant univariate effects on memory, self-perceived health, and activity director's ratings. Being intrigued by the memory finding, I conducted a follow-up study to further investigate the effect of a visitation program on cognitive functioning. In this second study the dependent measures included all of the cognitive variables included in the original study as well as some additional memory variables. The visitation program in the follow-up study had no effect on any of these measures. As a result of my failure to obtain a significant memory effect such as that reported in Reinke et al. (1981), I reanalyzed the data from the original study. In my reanalysis, the only significant effect was a borderline univariate effect for self-perceived health; the multivariate effect did not approach significance. On the basis of my inability to produce the results reported in Reinke et al. when I reanalyzed the original data, I must conclude that the friendly visitor program did not have the effects attributed to it in the original report.  相似文献
