We describe the first study with a home-based HIV prevention video program for parents and young teenagers. The objectives of the program are to inform parents and teenagers about the causes and prevention of HIV infection and other sexually transmitted diseases, to increase family problem-solving skills, and to increase teen problem-solving and assertiveness skills. The objectives pertain to the goals of increasing skills needed to help teenagers avoid or manage high-risk behaviors and situations. Forty-five families with at least one 12- to 14-year-old were randomly assigned to either experimental (receive video program) or control (no video) conditions in a pretest-posttest design. After 6 months (Follow-Up 1), the experimental and control families were reassessed. The control families next received the video program, and the control families were assessed again (Follow-Up 2). The results indicate increases in parent and teen knowledge and skills only with video viewing. Approaches to improving the video program, particularly with teenagers, are discussed. 相似文献
Objective: Poor physical health in childhood is associated with a variety of negative health-related outcomes in adulthood. Psychosocial pathways contributing to the maintenance of physical health problems from childhood to young adulthood remain largely unexamined, despite evidence that factors such as negative mood and stress impact physical health.
Design: The current study tested the direct and indirect effects of ongoing health, chronic stress, health-related chronic stress, and depressive symptoms at age 20 on the link between health problems in childhood and young adulthood (age 21) in a longitudinal sample (n = 384).
Main Outcome Measures: The hypotheses were tested using a multiple mediation path analysis framework; the primary outcome measure was a composite index of health status markers in young adulthood.
Results: The proposed model provided an adequate fit for the data, with significant total indirect effects of the four mediators and significant specific indirect effects of health-related chronic stress and depressive symptoms in maintaining health problems from childhood into young adulthood.
Conclusions: Health problems are maintained from early childhood into young adulthood in part through psychosocial mechanisms. Depressive symptoms and health-related chronic stress have significant, unique effects on the relationship between health problems in early childhood and young adulthood. 相似文献
There is extensive documentation that the sex of organizational members may bias a wide variety of managerial decisions and workplace outcomes. While such effects have been persuasively demonstrated, the sex context of these effects has received little attention. It is argued here that it is not merely the sex of the actor, but the nature of the dyadic match (male/male; female/female; male/female; female/male) that is a critical influence on outcomes. This hypothesis is strongly supported by gross differences in workplace justice outcomes based on the dyadic composition of the actors involved in dispute proceedings (n=369) in a field setting. These results are tempered, however, inasmuch as analysis also indicates differences in the severity of disputed issues across these dyadic compositions. 相似文献
Any individual living or working in an odorous environment can experience changes in odor perception, some of which are long lasting. Often, these individuals report a significant reduction in the perception of an odor following long-term exposure to that odor (adaptation). Yet, most experimental analyses of olfactory adaptation use brief odorant exposures which may not typify real-world experiences. Using a procedure combining long-term odor exposure in a naturalistic setting with psychophysical tests in the laboratory, we present evidence to show that reduced odor intensity following long-term exposure is accompanied by odorant-specific shifts in threshold. Subjects were exposed continuously to one of two odorants while in their home for a period of 2 weeks. Exposure produced an odorant-specific reduction in sensitivity and perceived intensity compared with preexposure baselines: Detection thresholds for the adapting odorant were elevated following exposure and perceived intensity ratings for weak concentrations were reduced. For most individuals, reduced sensitivity to the test odorant was still evident up to 2 weeks following the last exposure. The persistence of the change, as evidenced by the duration of recovery from adaptation, distinguishes this phenomenon from the adaptation seen following shorter exposures and highlights the need for the study of exposure durations that are more similar to real-world exposures. 相似文献
Fifty-six pairs of male college students competed in games of electronic table tennis. The participants were led to expect a bias in the game equipment, such that one player would have an advantage and the other a disadvantage. All participants recorded levels of aspiration both before and after being informed of the alleged bias. Upon completion of the game, the subjects made ratings of causal attribution to five factors: ability, task difficulty, effort, luck, and equipment bias. The results showed that the students with the putative disadvantage set significantly lower aspiration levels and performed at a significantly lower level than those students with the supposed advantage. Thus the putative bias became a real bias, although a psychological rather than a physical one. It is suggested that the source of the bias and the performance differences was a self-fulfilling prophecy. In contrast to the results of earlier studies, there were no meaningful differences in ratings of causal attribution. 相似文献
