In response to the problem of adolescent smoking and limited appropriate cessation resources, this study examined the pattern and structure of the American Lung Association, Why Do You Smoke? (WDS) to determine its appropriateness for use in youth smoking cessation programs. The WDS is used to help smokers identify primary motivations for using tobacco and is comprised of eight subscales, each with three items representing primary smoking motivations ("Stimulation," "Handling," "Pleasure," "Crutch," "Psychological," "Habit," "Peer," and "Independence"). Study participants were all minors enrolled in a tobacco cessation program (n = 251). The pattern and structure of this self-assessment was examined using a correlated multiple group component factor analysis as a confirmatory approach. Findings show that the level of endorsement (as evidenced by subscale means and standard deviations) was relatively large across the eight subscales. Alpha coefficients ranged from .54 to .85. Results also underlined that the pattern coefficient matrix provided support for the hypothesized subscales through an examination of simultaneously extracted confidence intervals. These subscales should be further examined as to their usefulness in cessation interventions, such as the validity of using this instrument by gender, ethnicity, and age. However, from a measurement perspective, the confirmatory analysis provides excellent credence for the continued use of the WDS in cognitive/behavioral intervention programs targeting adolescents. 相似文献

OBJECTIVE AND PARTICIPANTS: The authors assessed the stability of diet and physical activity and their relationship to weight changes in first-year university women. METHODS: They collected anthropometric and body composition data from 101 resident women at the beginning of their first year of college and again at 12 months. The authors obtained physical activity and dietary logs 4 times throughout the year. RESULTS: Caloric intake decreased over 12 months in all participants (p = .01). There was little change in physical activity in participants who lost weight (p = .73, d = .18). Those who gained weight experienced a trend toward decreased physical activity (p = .13, d = .38). A significant Time X Group interaction on physical activity (p = .04) suggests that physical activity patterns differed substantially between individuals who gained weight and those who lost weight. CONCLUSIONS: Reduction in physical activity appears to be the defining characteristic in freshman weight gain. 相似文献

Traditional treatment of work-related musculoskeletal disorders focuses on the body functions and body structures aspects of the injury, with little or no attention paid to ergonomics as a form of treatment. The use of ergonomics in preventing disability in injured workers is a relatively new area of study. There are a number of factors that may contribute to the lack of emphasis on ergonomic interventions in the prevention of disability following musculoskeletal injury. For instance, a review of the knowledge base suggests that there is a lack of a formal conceptualization or standardized approach to ergonomics in the return to work process. In part, this lack of consistency may be due to the varied disciplinary backgrounds of ergonomists, leading individuals to view ergonomics from a specific perspective, rather than utilizing a transdisciplinary approach. The purpose of this paper is to introduce a new practice model of occupational rehabilitation ergonomics. The model draws upon the International Classification of Functioning, Disability, and Health (ICF) and merges this with basic ergonomic and rehabilitation principles. 相似文献

This study examined system barriers that precluded injured workers from accessing services and supports in the return-to-work (RTW) process. A grounded theory approach was used to investigate injured worker experiences. Methods included in-depth telephone interviews and the constant comparative method to analyze the data. Findings revealed that consumers experienced tensions or a tug-of-war between the RTW system, the health care system, and in accessing and using knowledge. Over time consumers reflected upon these tensions and initiated strategies to enhance return to function and RTW. Insights from consumer-driven strategies that might inform future policy change and promote positive service delivery for injured workers are examined. 相似文献

We document the impact of the AIDS crisis on non-AIDS-related health services in 14 sub-Saharan African countries. Using multiple
waves of Demographic and Health Surveys (DHS) for each country, we examine antenatal care, birth deliveries, and rates of
immunization for children born between 1988 and 2005. We find deterioration in nearly all these dimensions of health care
over this period. The most recent DHS survey for each country collected data on HIV prevalence, which allows us to examine
the association between HIV burden and health care. We find that erosion of health services is the largest in regions that
have developed the highest rates of HIV. Regions of countries that have light AIDS burdens have witnessed small or no declines
in health care, using the measures noted above, while those regions shouldering the heaviest burdens have seen the largest
erosion in non-HIV-related health services for pregnant women and children. Using semiparametric techniques, we can date the
beginning of the divergence in the use of antenatal care and in children’s immunizations between high- and low-HIV regions
to the mid-1990s. 相似文献

It is often asserted that the gender gap in educational attainment is larger for blacks than whites, but historical trends
comparing the black and white gender gap have received surprisingly little attention. Analysis of historical data from the
U.S. census IPUMS samples shows that the gender gap in college completion has evolved differently for whites and blacks. Historically,
the female advantage in educational attainment among blacks is linked to more favorable labor market opportunities and stronger
incentives for employment for educated black women. Blacks, particularly black males, still lag far behind whites in their
rates of college completion, but the striking educational gains of white women have caused the racial patterns of gender differences
in college completion rates to grow more similar over time. While some have linked the disadvantaged position of black males
to their high risk of incarceration, our estimates suggest that incarceration has a relatively small impact on the black gender
gap and the racial gap in college completion rates for males in the United States. 相似文献

Although a homophobic and sexist archetype of heterosexual masculinity has been thought to permeate competitive teamsport, matters have been rapidly changing. This is evident in research on openly gay athletes, attitudes among heterosexual athletes, and recent studies on decreasing homophobia among sport media content. In this research, however, we examine how some men still adhere to a homophobic and sexist masculine deposition when discussing sport on the Internet. A textual analysis was used to analyze hegemonic masculinity from a popular American football message board. Although posts related to hegemonic masculinity did not permeate the data, we found that this traditional form of masculinity was upheld through misogyny, homophobia, and the objectification of women. Thus, whereas mainstream sport media is increasingly policed for homophobia and sexism, this research shows that the anonymity of the Internet permits hegemonic masculinity to flourish in specific locations, without contestation. 相似文献

The purpose of this study was to examine sport fans' impressions of gay male athletes. Participants formed impressions of a fictional athlete from their favorite team after reading a short scenario about the player. The scenarios described the athlete as being gay or straight, and either becoming a distraction or not causing a distraction to the team. While males' ratings of the athlete did not significantly differ, female fans formed significantly more positive impressions of the gay male player than the straight athlete. These results are discussed in terms of the ingroup bias and the shifting culture of homophobia in sport. 相似文献
