Effects of social support and coping of family caregivers of older adults with dementia in Taiwan.

The purpose of this study was to explore the relationship of demographic characteristics, contextual factors, social support, and coping on health outcomes of family caregivers of older adults with dementia in Taiwan. This study also examined caregiving stress and whether support moderated the effects of caregiver stress on health. Lazarus and Folkman's (1984) Stress model guided this study. The descriptive cross-sectional study included subjects who were primary family caregivers of older adults with dementia from two settings in southern Taiwan. A convenience sample of 148 participants was interviewed. Data analysis consisted of Pearson's correlations, and simple and multiple regression analysis. Findings indicated that younger caregivers, those with paid assistants, and those with longer duration of caregiving had better health. Females with lower income and without assistants had more depressive symptoms. In addition, moderating effects of social support were supported. The results from this study provided a basis for developing interventions to minimize negative impacts on caregivers.

Disciplinary action against physicians: who is likely to get disciplined?

PURPOSE: We sought to determine the characteristics of disciplined physicians at-large and the risk of disciplinary action over time and to report the type and frequency of complaints and the nature of disciplinary actions against allopathic physicians in Oklahoma. METHODS: Descriptive statistics, Kaplan-Meier analysis, and Cox proportional hazards modeling of publicly available data on physicians licensed by the Oklahoma Board of Medical Licensure and Supervision. RESULTS: Among 14,314 currently or previously licensed physicians, 396 (2.8%) had been disciplined. Using univariate proportional hazards analysis, men (P <0.04), non-whites (P < 0.001), non-board-certified physicians (P < 0.001), and those in family medicine (P < 0.001), psychiatry (P < 0.001), general practice (P < 0.001), obstetrics-gynecology (P < 0.03) and emergency medicine (P < 0.001) were found to be at greater risk of being disciplined than other medical specialty groups. Foreign medical graduates had a higher risk of disciplinary action compared to US medical graduates (P < 0.001), although this finding was not confirmed by multivariate analysis. Kaplan-Meier analysis revealed that the proportion of physicians disciplined increased with each successive 10-year interval since first licensure. Complaints against physicians originated most often from the general public (66%), other physicians (5%), and staff (4%), and the complaints most frequently involved issues related to quality of care (25%), medication/prescription violations (19%), incompetence (18%), and negligence (17%). CONCLUSION: To improve physician behavior and reduce the need for disciplinary action, medical schools and residency training programs must continue to emphasize both patient care and medical professionalism as critical core competencies.

Depressive symptoms and learned resourcefulness among Taiwanese female adolescents.

Depression in adolescents is a widespread problem and has negative consequences on mental health, including suicidal tendencies. Worldwide, this condition is twice as prevalent in females as in males. To identify factors that may affect the development of depression in female adolescents in Taiwan, a cross-sectional, correlational design was used to examine the relationships among stressors, learned resourcefulness, and depressive symptoms. Four hundred four Taiwanese female adolescents participated in the study. Descriptive statistics and hierarchical multiple regression were used to analyze data. The study findings suggested that low household income, dissatisfaction with grades, perceived poor health state, and poor peer relationships were significant stressors that contribute to the development of depressive symptoms. Adolescents with greater learned resourcefulness had fewer depressive symptoms. In addition, learned resourcefulness mediated the effects of perceived health and peer relationships on depressive symptoms. Health-care providers can use this knowledge to teach adolescents coping strategies such as use of learned resourcefulness to prevent depression and its negative consequences.

Nonparametric estimation of the bivariate recurrence time distribution.

This article considers statistical models in which two different types of events, such as the diagnosis of a disease and the remission of the disease, occur alternately over time and are observed subject to right censoring. We propose nonparametric estimators for the joint distribution of bivariate recurrence times and the marginal distribution of the first recurrence time. In general, the marginal distribution of the second recurrence time cannot be estimated due to an identifiability problem, but a conditional distribution of the second recurrence time can be estimated non-parametrically. In the literature, statistical methods have been developed to estimate the joint distribution of bivariate recurrence times based on data on the first pair of censored bivariate recurrence times. These methods are inefficient in the model considered here because recurrence times of higher orders are not used. Asymptotic properties of the proposed estimators are established. Numerical studies demonstrate the estimators perform well with practical sample sizes. We apply the proposed method to the South Verona, Italy, psychiatric case register (PCR) data set for illustration of the methods and theory.
