"Psychological examinations are frequently required for the evaluation of emotional and intellectual impairments in order to establish the degree of loss of function in workers who apply for disability benefits as well as in adults who are disabled in childhood… . The presence of severe and persistent illness should be associated with objective evidences of regression substantial enough to preclude vocational activity… . Psychological evaluations serve to pinpoint the specific functional capacities of the applicant so as to serve as a basis for the evaluation as well as for rehabilitation."

In this study the authors examined both preventive psychological coping resources and negative mood regulation expectancies as potential mediators between parental attachment and two types of stress outcomes: stress symptoms and stress-produced emotions. Data were collected from 390 college students and separate structural equation models were tested for the outcomes of stress symptoms and emotions. Results suggested that for both models, as hypothesized, preventive resources and negative mood regulation expectancies functioned as mediators. Further, there was evidence that these results were similar for the model in which stress symptoms were used as an outcome, as well as the model in which stress-produced emotions were used as the outcome. Implications for a more complete understanding of psychological resources promoted by secure attachment are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)  相似文献

This article explores the cultural construction of fatherhood in America, as well as the consequences of this construction as a motivator for understudying fathers—especially father love—for nearly a century in developmental and family research. It then reviews evidence from 6 categories of empirical studies showing the powerful influence of fathers' love on children's and young adults' social, emotional, and cognitive development and functioning. Much of this evidence suggests that the influence of father love on offspring's development is as great as and occasionally greater than the influence of mother love. Some studies conclude that father love is the sole significant predictor of specific outcomes after controlling for the influence of mother love. Overall, father love appears to be as heavily implicated as mother love in offsprings' psychological well-being and health, as well as in an array of psychological and behavioral problems.

Presents a brief overview of the career of Philip R. Laughlin. Philip R. Laughlin has made an outstanding contribution to the education and training of professional psychologists through his leadership in the Veterans Administration. As Chairperson for the Psychology Representation Training Committee, he has advised the VA on policy, affiliated programs, distribution of funds budgeted for psychology interns, and related matters. As Chair of the Committee on Psychology Training of the Association of VA Chief Psychologists and as a member of a number of VA committees and task forces, he has been a strong and articulate voice for psychology training in the VA system. He has also served as a member of the APA Committee on Accreditation, the Executive Committee of the Association of Psychology Internship Centers, and as recorder at the National Internship Training Conference in 1987. In all these roles, as well as in his work as Executive Officer for the Iowa Psychological Association, he has worked for the strengthening of support for, and excellence of, internship training in psychology.

The widespread use of complementary and alternative medicine techniques, often explored by patients without discussion with their primary care physician, is seen as a request from patients for care as well as cure. In this article, we discuss the reasons for the growth of and interest in complementary and alternative medicine in an era of rapidly advancing medical technology. There is, for instance, evidence of the efficacy of supportive techniques such as group psychotherapy in improving adjustment and increasing survival time of cancer patients. We describe current and developing complementary medicine programs as well as opportunities for integration of some complementary techniques into standard medical care.  相似文献
