Guided by a stress process perspective, we investigated (a) whether marital conflict might directly lead to changes in depression and functional impairment, (b) whether marital conflict might indirectly lead to changes in functional impairment via depression, and (c) whether marital conflict might indirectly lead to changes in depression via functional impairment. We estimated a latent variable causal model using 3 waves of data from the National Survey of Families and Households (N = 1,832). Results indicated that marital conflict directly led to increases in depression and functional impairment and indirectly led to a rise in depression via functional impairment. Overall, findings suggest marital conflict is a significant risk factor for psychological and physical health among midlife and older adults.  相似文献

The present study evaluated the effects of a cognitive‐behavioral program on disruptive and delinquent behaviors among a sample of adolescent girls placed in a residential center in Quebec (Canada). This study also investigated the moderating impact of depressive symptoms on program effectiveness. The study used a quasi‐experimental design to allow comparisons between 104 girls in the treatment group and 78 girls in the comparison group over 18 months. Findings showed that the program contributed significantly, albeit modestly, to a decline in some forms of disruptive/delinquent behaviors. Results also indicated that girls with a higher level of depressive symptoms at admission also reported higher involvement in a myriad of disruptive/delinquent behaviors and that for some types of problem behaviors, this higher involvement persisted over time. In general, however, the seriousness of the depressive symptoms that the girls reported at admission did not interfere with the effectiveness of the cognitive‐behavioral program.  相似文献

Regression analysis for competing risks data can be based on generalized estimating equations. For the case with right censored data, pseudo-values were proposed to solve the estimating equations. In this article we investigate robustness of the pseudo-values against violation of the assumption that the probability of not being lost to follow-up (un-censored) is independent of the covariates. Modified pseudo-values are proposed which rely on a correctly specified regression model for the censoring times. Bias and efficiency of these methods are compared in a simulation study. Further illustration of the differences is obtained in an application to bone marrow transplantation data and a corresponding sensitivity analysis.  相似文献

Low socio-economic groups are typically difficult to recruit and retain in health research, which makes it difficult to investigate their health-related beliefs and behaviours. Low socio-economic parents with overweight or obese children took part in a longitudinal qualitative child obesity study over 12?months. These parents’ views of and recommendations for appropriate recruitment and retention strategies are reported. Their interpretations and suggestions are considered in the light of the difficulties that were experienced in designing the study to meet their needs and the approaches that were found to be more effective in achieving and maintaining a viable study cohort. Relevant aspects of recruitment included remuneration, recruitment locations and the use of appropriate weight-related terminology. Retention factors included protocol flexibility, ongoing remuneration and learning opportunities. Barriers to ongoing participation are also discussed. Suggestions are provided for future qualitative research with low socio-economic families.  相似文献

In the early twentieth century, Australians committed to nation-building had to be inventive. With neither a foundation myth nor a unique defining history to resort to, other cultural products were created to succour Australia's postcolonial development. Whereas one such cultural product, the Sydney Bulletin, has been examined in Australian historiography, the role of encyclopaedias has been neglected. It is argued here that the Australian Encyclopaedia (1925–26) plumped the cheeks of the nation; and that encyclopaedias, despite their claims to objectivity, are surprisingly effective in the communication of political ideas.  相似文献

Residents of the county of Osterg?tland, Sweden, who were 16-64 years of age in December 1984 and not pensioned (n=229,864), were followed in a prospective, cohort, study of data collected between 1985 and 1996. Using survival methods as the method of analysis, the likelihood of being granted a disability pension was 14% for women, 11% for men, and increased with age. Women less than 54 years of age were at higher risk than men (P<0.001), 69% of disability pensions granted were full-time and 31% were part-time, more women received part-time pensions (P<0.001). Whether the differences observed are due to gender bias in social insurance practices, to disease patterns, to occupational and work-related factors, or to a cohort effect has yet to be determined.  相似文献

Social entrepreneurship has emerged as an important means of addressing grand challenges. Although research on the topic has accelerated, scholars have yet to articulate an overarching framework that links the different pathways taken by social entrepreneurs with the positive effects of these efforts. To address this shortcoming, we conducted a systematic literature review which enabled us to conceptually differentiate between social value and social change as distinct outcomes of social entrepreneurship and identify seven pathways for achieving these outcomes. Building on our analysis, we outline a research agenda for questions pertaining to: the dynamics between social value and social change; how contextual factors and social entrepreneurs influence various pathways; design principles of business models and innovations that facilitate social value and social change; and defining, measuring, and ensuring accountability for social value and social change.  相似文献
