Social diffusion theory has recently been recognized as a promising approach for large-scale disease prevention and health promotion efforts. This paper describes how principles and tactics from social cognitive theory, operant psychology, social psychology, social marketing, and the overarching stages of change model can be used to further develop the conceptual and strategic (technological) bases of social diffusion theory. Within an integrative framework, we discuss in detail more effective ways to train peer mediators of behavior change as one example of how social diffusion theory can benefit from this conceptual and strategic reformulation. We then further illustrate the use of peer mediators of change in human immunodeficiency virus (HIV) and cancer prevention intervention studies with both interventions training peer mediators to diffuse information, norms, and risk reduction strategies. Although the results of these studies showed reductions in high-risk behaviors across population segments, more closely following the framework discussed in this article should further increase the behavior change potential of future interventions based on social diffusion theory. 相似文献

Large numbers of America's young people engage in multiple high-risk behaviors that may jeopardize their health and social development. Given the gravity of this situation, many federal agencies and national organizations have called for the implementation of school-based K-12 social competence and health promotion programs. Unfortunately, there is a gap between the comprehensive programs that policymakers are asking educators to implement and the limited scope, duration, and intensity of state-of-the-art health promotion programs that scientists have developed and evaluated. As a result, most schools currently adopt well-marketed programs that lack documented effectiveness. Although current research indicates that brief, well-designed, theory-driven competence promotion and health education programs produce short-term benefits, there have been no controlled, longitudinal field studies to evaluate the long-term effects of K-12 efforts. This paper proposes that policymakers and funding agencies support long-term collaborations among educators and scientists to develop and evaluate K-12 comprehensive social competence and health education programs and identifies critical issues that funded projects should address. 相似文献

Converging evidence supports a left hemisphere role in defensive repression and sensation seeking. This led to the hypothesis that students with a relatively active left hemisphere would perform poorly during 8 weeks of a college class. The measure of relative hemispheric activation was the visual line-bisecting task given early in the course. The hypothesis was supported. Previous evidence that activation asymmetry is stable over time was supported because the single measurement of line bisecting was a longitudinal predictor of multiple behaviors. A temporal pattern of increasing correlation between the bisecting and performance measures favors a feedback repression model. Alternative explanations based on sensation seeking, subject-matter repression, and cooperation were considered but not eliminated. 相似文献

The counter model for word identification (Ratcliff & McKoon, 1997) has been challenged by recent empirical findings that performance on low-frequency words improves as the result of repetition of the words. We show that the model can accommodate this learning effect, and that it can do so without jeopardizing its explanations of the effects on word identification of a large number of other variables. 相似文献

A stochastic model is proposed to account for the behavior of subjects in recognition tasks in which stimuli are presented, one at a time, in a protracted sequence. The basic assumption is that the memory trace resulting from the presentation of a particular stimulus not only fades away during the presentation of subsequent stimuli but also diffuses in such a way as to become decreasingly stimulus specific. An account is thereby provided for both (a) the increase in the probability of false recognition with the total number of stimulus presentations and (b) the departure of curves of forgetting from the previously proposed simple exponential decay functions. An expression for the amount of information carried along when the number of stimulus presentations becomes large is then derived for subjects who conform with the model.The author has benefited from discussions of this work with J. W. Tukey, J. R. Pierce, E. N. Gilbert, and D. Slepian of the Bell Telephone Laboratories and with G. A. Miller of Harvard University. 相似文献

The study employs a daily diary design to assess self-esteem reactivity and its association with children's aggressive behavior. We test the hypothesis that the self-esteem of aggressive children will be more reactive to negative interpersonal events than the self-esteem of nonaggressive children. Results provide partial support for the aggression/reactivity hypothesis. Aggressive children's self-esteem was more reactive to negative peer events but less reactive to negative adult events than the self-esteem of less aggressive children. These findings are discussed in relation to the experimental literature relating self-esteem instability and ego-threat to aggression and in relation to the extensive body of research on childhood aggression. Intervention implications are also considered. 相似文献

Background
11 out of 35 male employees of a central alert team with rescue coordination function developed a tinnitus disorder. This clinical case-study highlights the psychodynamic background of this accumulation.Methods
Employees were investigated by psychometric questionnaires and semistructured psychodynamic biografical interviews. Additionally aspects of group dynamics and organisational structure were assessed.Results
All staff members reported adverse work conditions. Medical and psychometric examination of the tinnitus patients did not reveal severe pathological findings. The interviews identified psychodynamic conflicts dealing with autonomy and regulation of self-esteem. All tinnitus patients reported a very adverse or punitive father relation and difficulties in performing a stabile male role and self-image. Group dynamics was dominated by paranoid and regressive tendencies complicated by maladaptive coping, crude perception of external facts and a pronounced experience of aggressive impulses.Conclusion
The remobilisation of infantile powerlessness, ineffectiveness and helplessness triggered by adverse work conditions and the introduction of a new culture of personal responsibility within the work organisation together with an impaired coping of separation conflicts enforced by traumatic aspects of the relation with the father may have promoted the tinnitus symptomatology. Additionally, due to the missing awareness of the importance of such group dynamical processes the employers contributed to an increasing psychosocial distress, which promoted the accumulated manifestation of tinnitus as a conflict expressive symptom. 相似文献98.

Recently, G. C. Van Orden, J. G. Holden, and M. T. Turvey (2003) proposed to abandon the conventional framework of cognitive psychology in favor of the framework of nonlinear dynamical systems theory. Van Orden et al. presented evidence that "purposive behavior originates in self-organized criticality" (p. 333). Here, the authors show that Van Orden et al.'s analyses do not test their hypotheses. Further, the authors argue that a confirmation of Van Orden et al.'s hypotheses would not have constituted firm evidence in support of their framework. Finally, the absence of a specific model for how self-organized criticality produces the observed behavior makes it very difficult to derive testable predictions. The authors conclude that the proposed paradigm shift is presently unwarranted. 相似文献

Mental health courts have developed as one response to persons with mental illness who are involved with the criminal justice system. This study investigated the efficiency and safety goals of one such court in Broward County, FL. Mental health court (MHC) clients spent significantly fewer days in jail for the index arrest associated with study enrollment than a comparison group. MHC clients had similar survival time to re-arrest up to one year after study enrollment. MHC clients did not significantly differ from the comparison group in self-reported aggressive acts over an 8 month follow-up period, while they did self-report significantly fewer acts of violence than the comparison group at the 8 month follow-up. These findings suggest that some of the benefits associated with the MHC reported in prior studies were not achieved at the expense of efficiency and safety. 相似文献
