We describe three experiments testing treatments to promote the performance of health-protective dental behaviors. Subjects included 55 women from an introductory psychology course (Experiment 1), 45 men and women (Experiment 2), and 81 older-than-average students identified as at risk for gum disease (Experiment 3). The interventions, derived from social cognitive theory, included health education, skills training, and self-monitoring. In each study, we examined the contribution of additional treatment components, including social support (Experiment 1), intensive contact (Experiment 2), and flexible goal setting (Experiment 3). Across experiments, the behavioral results were remarkably similar: Subjects exhibited excellent adherence while in the study but, at follow-up, reported behavior that differed little from baseline. We discuss parallels between attempts to promote health-protective dental behaviors and other health-promotion programs, and we describe different perspectives from which to address the problem of creating healthy habits.  相似文献

La littérature portant sur la culture des organisations souffre d'un manque manifeste d'enquêtes extensives débouchant sur des études comparatives. Afin de rendre plus comparables les cultures organisationnelles, nous proposons une définition et une série de dimensions. La culture organisationnelle renverrait aux perceptions communes des pratiques de travail dans le cadre des unités constitutives des organisations. A l'examen d'études empiriques, les cinq dimensions suivantes nous sont apparues: autonomie, orientation externe, coordination interdépartementale, orientation vers les ressources humaines et orientation vers le développement. L'utilisation de cette définition et de ces dimensions générales devrait faciliter la comparaison des cultures organisationnelles et l'accumulation de résultats.
Within the body of organisation culture literature, there is a conspicuous absence of large-scale studies reporting on comparative studies. In order to increase comparability of organisational cultures we propose a definition and a set of dimensions. Organisational culture is defined as shared perceptions of organisational work practices within organisational units. On the basis of empirical studies we discerned the following five dimensions: autonomy, external orientation, interdepartmental coordination, human resource orientation, and improvement orientation. Use of this definition and a set of such generic dimensions would facilitate the comparison of organisational cultures and the accumulation of research findings.  相似文献

In this introduction to the special issue on teaching about gender and ethnicity in psychology, we consider the assumptions underlying an inclusive curriculum that pays attention to gender and ethnicity and address why such a curriculum has merit. We review empirical studies, assessing whether existing curricula are inclusive, and present an overview of the articles and the recurrent themes. These themes include the complexity of the interaction between ethnicity and gender; the difficulty of deciding which of the many possible ethnic groups to include in course material; the dominance of evaluative comparison in discussions of differences among groups; the interdisciplinary nature of research on ethnicity; and the tendency in psychology to ignore the importance of the power differences that confound analyses of the effect of ethnicity and gender.  相似文献

Adult age differences in the consistency effect were examined in 3 experiments. The consistency effect refers to items inconsistent with expectations being better remembered than items consistent with expectations. Younger and older adults walked into an office room and viewed objects that varied in their consistency with expectation. Immediate and delayed recognition tests on item information (i.e., distractors were defined by their semantic identity) revealed that both age groups recognized unexpected items better than expected items. However, when recognition of token information was requested (i.e., distractors were defined by their physical appearance), younger adults, in contrast to older adults, exhibited consistency effects. Also, under divided attention, young adults revealed the same pattern of data as did elderly adults under full attention. The results are discussed in terms of capacity-related differences in distinctive encoding.  相似文献

We investigated motivational and cognitive processes of behavior change with respect to mammography screening. One hundred forty-two women (ages 40 and older) recruited from three worksites answered a 41-item questionnaire consisting of statements based on constructs from the transtheoretical model of behavior change. Principal-components analysis identified two factors: a six-item component representing positive perceptions of mammography (Pros) and a six-item component representing avoidance of mammography (Cons). Analysis of variance showed that Pros, Cons, and a derived Decisional Balance measure (Pros minus Cons) were associated with stage of mammography adoption. Results are consistent with applications of the model to smoking cessation. The model is also discussed as it relates to other theories of behavior change and as a general strategy for analyzing perceptual data pertinent to health-related actions and intentions for behavioral change.  相似文献
