Eighty dental patients were pretested with a scale measuring health locus of control and then exposed to a persuasive communication designed to manipulate their beliefs about the seriousness of periodontal disease and their susceptibility to it. The high seriousness condition increased feelings of fear, concern, and threat as well as intentions and reported compliance with recommended oral hygiene procedures. However, patient's perceived personal efficacy in performing the recommended behavior was the most important predictor of subsequent behavior. The implications of the results for Roger's protection motivation theory are discussed.  相似文献

Two experiments compared the perception of apparent movement when the second of two successive stimuli always appeared in the same position and when it varied randomly between two spatial positions. The results of both experiments showed that foreknowledge of the position of the second stimulus does not facilitate the perception of apparent movement. Experiment 2 also clearly showed that the space-time relationships of Korte’s third law of apparent movement does not depend on foreknowledge of the position of the second stimulus. These findings imply that apparent movement in real time occurs after the second stimulus has been registered by the visual system. It suggests that apparent movement involves a delayed decision mechanism that stores the first stimulus, the interstimulus temporal interval, and the second stimulus, and then impletes a motion compatible with the stimulus information.  相似文献

The assessment of worry among older adults typically has involved measures designed with younger cohorts. Because of special concerns in assessing older adults, modifications to existing instruments may be necessary. Addressing equivocal factor analytic data on the Penn State Worry Questionnaire (PSWQ) among younger adults, the authors conducted confirmatory factor analyses to evaluate the generalizability of previous models to older adults with generalized anxiety disorder. Data fit poorly with established single- and two-factor models. The single-factor model was modified, resulting in the elimination of 8 items, strong fit indices, high internal consistency, adequate test-retest reliability, and good convergent and divergent validity. Further psychometric work is required to assess whether the revised model is a more parsimonious method to assess late-life anxiety.  相似文献

Medical decision making often utilizes subjective observations to arrive at concrete judgments. The decisions frequently affect who receives scarce medical treatments and, thus, who lives or dies. In this paper, a model health status index is described. It is specific for the problem of choosing patients for hemodialysis or transplantation. Such a health status index may be designed for any medical decision involving such issues as drug treatment priorities, identification of salvageable patients, and selection of patients for scarce medical treatment. This index (1) incorporates a physician's own medical criteria and values, (2) can be modified as the data base improves, (3) assures consistency from decision to decision, and (4) can be developed and used without the help of a mathematician or computer.  相似文献
