The present study aimed to investigate the causal attributional dimensions used in the dissolution of premarital romantic relationships by using the subjects' own ratings, and to examine cultural influences on such dimensions. Twenty-two items tapping dimensions revealed by previous research were prepared and administered to 135 Turkish students who have broken up a relationship within the past year. Respondents' ratings of their perceived principal reason for dissolution were subjected to factor analysis which revealed the following six factors: self-control, partner's control, control external to the relationship, partner's lack of caring, instability, and transitoriness. The relationship between negative emotional reaction to the breakup and attributional dimensions and other dating-related variables revealed that the intensity of involvement and attributing the dissolution to external factors increases, whereas, initiating the breakup decreases the negative emotional impact of such an experience. The results of the study were greatly overlapping with the findings reported in the western literature. The implications of the results were discussed in relation to research in heterosexual relationships. 相似文献

Recently it has been suggested that social-psychological profiles of suicide attempters are useful to identify high-risk persons. There also is evidence that the complexity of interpersonal and intrapersonal factors constrict the extent to which such identification can be made. Using data from a nonprobability sample of 455 adolescent and youthful committers to test the hypothesis that attempters and committers do not differ with respect to environmental and stress-producing factors, the results reveal some differences between committers and attempters. Social-psychological characteristics of committers and factors relating to their social support systems are also discussed in the context of these differences. 相似文献

Work values and key influencers of a sample of black male and female adolescents were examined. Results indicated that boys and girls valued both the intrinsic and extrinsic rewards of work; however, girls reported slighter stronger extrinsic values than did boys. In addition, the sexes reported differences in the importance of specific work values such as "making lots of money," and "doing important things." When naming a key influencer, respondents tended to cite a same-sex and race individual. Sex of one's key influencer was related to certain work values, with subjects reporting a male key influencer valuing "trying out one's own ideas" and "having a secure future" more than those reporting a female key influencer. The interaction of sex of subject and sex of key influencer was significant on one of the work value outcomes. Implications of these findings are considered. 相似文献

This study examines the relationship between the age of unmarried fathers and their self-concept and anxiety level. A total of 24 unmarried fathers (12 adolescents and 12 adults) comprised the sample. No significant differences were found between adolescent and adult fathers on self-concept or anxiety level. Findings are discussed with regard to the current status of research on adolescent fathers. 相似文献
