Identity development and perceived parental behavior as sources of adolescent egocentrism 总被引:3,自引:0,他引:3
Brian P. O'Connor 《Journal of youth and adolescence》1995,24(2):205-227
Adolescent egocentrism involves heightened self-consciousness and feelings of uniqueness (O. Elkind [1967], Egocentrism in Adolescence, Child Development, Vol. 38, pp. 1025–1034). Some studies have found that adolescent egocentrism is associated with identity development, and other studies have found that egocentrism is associated with perceptions of parental behavior. The purposes of this investigation were to simultaneously examine the associations between these variables (1) to determine whether identity development and perceived parental behavior display separate or overlapping associations with adolescent egocentrism, and (2) to clarify the directions of the relationships between these variables. Four hundred eighteen subjects from 12 to 21 years of age completed established measures of identity development, perceived parental behavior, and egocentrism. Identity development was more strongly and consistently related to egocentrism (egocentric adolescents tended to be identity achieved or to be experiencing an identity crisis), whereas perceived parental behavior accounted for little additional variance. The results also clarify differences between the two primary measures of adolescent egocentrism (the Adolescent Egocentrism Scale and Imaginary Audience Scale).Received his M.Sc. and Ph.D. from the University of Victoria.

Challenges the use by policy researchers of a model for comparing adolescent and adult decision making that is based on informed consent standards. An expanded decision-making framework designed to evaluate judgment in adults and adolescents can better test the empirical basis of paternalistic legal policies. The theoretical and empirical literature on the informed consent framework is critiqued and an alternative framework incorporating judgment factors is proposed. Three judgment factors—temporal perspective, attitude toward risk, and peer and parental influence—and their effects on decision making are explored. Finally, implications for future research are analyzed in several decision-making contexts.Several of the ideas in this article were originally presented by the first author and were published as part of a symposium on competence (see Scott, 1992). The current article expands and refines these ideas, provides a more substantial research base, and suggests several future research directions. We thank Joseph Allen, Richard Bonnie, Baruch Fischhoff, William Gardner, John Monahan, Edward Mulvey, Richard Redding, Paul Slovic, and three anonymous reviewers for their helpful comments. Special thanks to Thomas Grisso for providing much constructive criticism and to Wendy Shang for outstanding research assistance. Finally, we would like to acknowledge the MacArthur Foundation, which supported this work in its early stages. 相似文献

This article reports the development and psychometric properties of three standardized and objectively scored measures, the MacArthur Treatment Competence Research Instruments. They were designed to assess abilities related conceptually to four legal standards for competence to consent to treatment: understanding, appreciation, rational manipulation (reasoning), and expressing a choice. Scoring reliability, internal consistency, intertest correlations, and test-retest correlations were examined with data from samples of hospitalized patients with schizophrenia, major depression, and ischemic heart disease, as well as matched non-ill community samples. The results indicate very good interscorer reliability and provide guidance for the use of the instruments and interpretation of their results in future research on patients' decisional abilities in treatment contexts. 相似文献

Doe demonstrates that once an employer enters into a relationship with an individual and thereafter determines that he or she may be disabled, the employer has the right to ask the individual questions about the possible disability when those questions are relevant to assessing his or her qualifications for continuing on the job. In fact, once a health care provider is on notice that an employee's or physician's disability may render the employee or physician no longer qualified, thereby potentially endangering patients, the provider is required to determine whether the person is qualified for the job. In these sensitive matters, employers must draw a fine line between unreasonably following up on every rumor on the one hand, and on the other hand investigating reliable information when there may indeed be a direct threat to patients. 相似文献
