The pathways between differentiation of self and health remain only partly elucidated. This cross‐cultural study sought to test Bowen's hypothesis about the associations between differentiation, stressful life events, and physical and psychological health, in a sample of 466 Spanish adults. Results show that people with higher levels of differentiation were less prone to physical ailments (e.g., heart disease, cancer, or blood disorders) and psychological symptoms (e.g., depression or anxiety). Further, differentiation mediated the association between stress (i.e., perceived negativity of stress in the past year and number of stressful events across the lifetime) and physical and psychological health. The current research provides cross‐cultural empirical evidence for the links between differentiation and mind and body health in a Mediterranean culture. 相似文献

Fatigue is a critical issue for nurses that may lead to medical errors, degradation in performance, decreased mental acuity, and social problems. Poor sleep quality is also a contributing factor in fatigue that nurses experience. Therefore, the purpose of this study was to examine the differences in perceptions of fatigue between night-shift and day-shift nurses, as measured by scores on the Brief Fatigue Inventory (BFI) and to examine differences in sleep quality between the two groups, as measured by responses on the Pittsburgh Sleep Quality Index (PSQI). Univariate analysis of variance showed significant differences between the two groups on the BFI, with the night-shift cohort reporting higher mean scores on the BFI. Significant differences were also found between the two groups on PSQI mean scores, with the night-shift cohort reporting higher mean scores. Findings from this study suggest that night-shift nurses, compared with day-shift nurses, perceived a much higher level of fatigue and had poorer sleep quality. Further research is needed to evaluate interventions that might decrease fatigue in nurses and improve their sleep quality. 相似文献

Graphical representation of survival curves is often used to illustrate associations between exposures and time-to-event outcomes. However, when exposures are time-dependent, calculation of survival probabilities is not straightforward. Our aim was to develop a method to estimate time-dependent survival probabilities and represent them graphically. Cox models with time-dependent indicators to represent state changes were fitted, and survival probabilities were plotted using pre-specified times of state changes. Time-varying hazard ratios for the state change were also explored. The method was applied to data from the Adult-to-Adult Living Donor Liver Transplantation Cohort Study (A2ALL). Survival curves showing a ‘split’ at a pre-specified time t allow for the qualitative comparison of survival probabilities between patients with similar baseline covariates who do and do not experience a state change at time t. Time since state change interactions can be visually represented to reflect changing hazard ratios over time. A2ALL study results showed differences in survival probabilities among those who did not receive a transplant, received a living donor transplant, and received a deceased donor transplant. These graphical representations of survival curves with time-dependent indicators improve upon previous methods and allow for clinically meaningful interpretation. 相似文献

In the absence of a "gold standard," research on domestic violence relies primarily on self-report, the quality of which is known to decline as the length of the recall period increases. Eliciting valid and reliable self-report data is crucial to the development of prevention and intervention policies and services. Nevertheless, existing measures typically do not incorporate devices to facilitate respondents' recall of the lifetime experience of domestic violence. This article describes the application of the Life History Calendar (LHC) method (Freedman, Thornton, Camburn, Alwin, & Young-DeMarco, 1988) to increase a respondent's recall of domestic violence victimization over the lifecourse. The LHC method elicits memorable information of a personal nature (e.g., children's birth dates) and uses this information to facilitate the recall of less memorable events. A recent field test of this LHC measure indicates its utility in assessing domestic violence victimization, which takes place in a complex sequence of episodes and often involves multiple perpetrators over the lifecourse. 相似文献

This study uses Cox regression to assess the relationships among parental drug use, drug treatment compliance, and reunification from substitute care. The study finds that drug treatment compliance is associated with faster reunification, even when accounting for ongoing drug use and three parenting measures. The findings are consistent with a conceptual framework suggesting that certain client actions, such as drug treatment compliance, may serve as markers that substantially affect client outcomes. 相似文献

Previous research has linked expressed emotion (EE) levels and psychiatric symptomology, whereas other empirical efforts have examined the relationship between EE and marital relationship variables. Still other research has linked psychological conditions with acts of aggression, and the impact of marital issues within this domain of inquiry also has been explored. The study presented here examined the combined effects of EE, marital quality, and psychiatric symptomology on displays of verbal aggression by both relationship partners. Both husbands' and wives' reports of marital quality were predictive of both husbands' and wives' verbal aggression levels; here, reports of lower marital quality were associated with higher levels of verbal aggression. Additionally, husbands' and wives' reports of psychological symptomology in self and partner were important paths to marital quality, as were husbands' and wives' reports of EE levels. Further, some evidence was generated that supports the mediating role of marital quality with regard to EE and psychological symptomology. However, the overall fit indices of the models tested in this empirical effort were modest. Limitations that concern the instruments utilized in the present study are discussed in this regard. 相似文献

Many of the available methods for estimating small-area parameters are model-based approaches in which auxiliary variables are used to predict the variable of interest. For models that are nonlinear, prediction is not straightforward. MacGibbon and Tomberlin and Farrell, MacGibbon, and Tomberlin have proposed approaches that require microdata for all individuals in a small area. In this article, we develop a method, based on a second-order Taylor-series expansion to obtain model-based predictions, that requires only local-area summary statistics for both continuous and categorical auxiliary variables. The methodology is evaluated using data based on a U.S. Census. 相似文献
