AbstractThis article studies the consistency of a local density regression model under a supremum Hellinger distance. Such model applies a piecewise structure where a mixture of Dirichlet process model (MDP) is assigned as the fixed density on each piece. The piecewise construction is a straightforward way to establish sup–Hellinger consistency in a regression settings. A specific piecewise density example is presented in a simulation study. 相似文献

The weighted generalized estimating equation (WGEE), an extension of the generalized estimating equation (GEE) method, is a method for analyzing incomplete longitudinal data. An inappropriate specification of the working correlation structure results in the loss of efficiency of the GEE estimation. In this study, we evaluated the efficiency of WGEE estimation for incomplete longitudinal data when the working correlation structure was misspecified. As a result, we found that the efficiency of the WGEE estimation was lower when an improper working correlation structure was selected, similar to the case of the GEE method. Furthermore, we modified the criterion proposed by Gosho et al. (2011) for selecting a working correlation structure, such that the GEE and WGEE methods can be applied to incomplete longitudinal data, and we investigated the performance of the modified criterion. The results revealed that when the modified criterion was adopted, the proportion that the true correlation structure was selected was likely higher than that in the case of adopting other competing approaches. 相似文献

In 2008, Maddan, Walker and Miller promoted the use of the Body Mass Index (BMI) as a viable alternative to Sheldon's technique of somatotyping. Utilizing the BMI, Maddan Walker and Miller re-analyzed the original data from the Sheldon studies. This analysis indicated a statistically significant relationship between the two measures of somatotyping. Genovese wrote a response to this work suggesting the BMI is not a useful proxy for somatotyping individuals. We respond to Genovese's critique by providing a full explication of the Sheldon somatoype measure and an analysis of Sheldon's original data accounting for all of the different somatotypes identified. Analyses here indicate that the original somatotype measure was very subjective. Although not without flaws, the BMI provides an objective somatotype measure that is comparable, if not superior, to the measure promulgated by Sheldon. 相似文献

ABSTRACTKnowledge about methods to retain community mental health (CMH) clients in integrated primary and behavioral health care (PBHC) programs is needed to address longstanding health disparities. A preexisting data set that contained the clinical records of 446 PBHC program participants was used to examine whether baseline sociodemographic, health, and psychosocial characteristics predicted retention in care at 6 months post-enrollment. Results indicated that less than half of PBHC participants (43.7%) were retained in care, and approximately 17% of the variance in retention was explained by the inclusion of seven predictors in the model (overall health, medications, laboratory data, primary care provider, disorder type, transportation, and living arrangement). Clients with thought disorders were almost twice as likely as those with mood disorders to be retained in care, and greater frequency of prescribed medications also increased the likelihood of treatment continuation (ORs = 1.99 and 1.20, respectively). Future research should identify factors that improve retention in integrated PBHC programs overall, and among persons with mood disorders, in particular. 相似文献

This study examined spiritual coping mechanisms, beliefs about spirituality and participation in spiritual activities and in other positive activities among adolescents in foster care. A multidimensional measure of spirituality was developed for face-to-face interviews with 188 youth (ages 14–17) from diverse racial/ethnic backgrounds in the United States. Findings revealed 95% of youth believe in God, over 70% believe God is 'creator' and God is 'love', and 79% considered prayer a spiritual practice. Most youth said love and forgiveness help them heal. Two-thirds (67%) reported responding to 'bad or tragic things happening' by spending time alone, and over half responded by praying (59%) or sharing the problem with someone else (56%). Youth's top three spiritual goals were to follow God's plan for them, become a better person, and know their purpose in life. Based on the value youth ascribed to spiritual coping mechanisms, recommendations for policy and practice focus on the integration of spirituality into practice and caregiving for youth in foster care. 相似文献

We provide a decision theoretic approach to the construction of a learning process in the presence of independent and identically distributed observations. Starting with a probability measure representing beliefs about a key parameter, the approach allows the measure to be updated via the solution to a well defined decision problem. While the learning process encompasses the Bayesian approach, a necessary asymptotic consideration then actually implies the Bayesian learning process is best. This conclusion is due to the requirement of posterior consistency for all models and of having standardized losses between probability distributions. This is shown considering a specific continuous model and a very general class of discrete models. 相似文献

This study examined maintenance and booster effects of a brief couple intervention, the Marriage Checkup (MC), across 5 years. A subsample of 63 couples who benefitted from two previous MCs (responder couples), were randomly assigned to a third MC or control. Before randomization (at 4-years-9-months), the responder sample had maintained small to medium effects on two measures of relationship functioning. After randomization, we found no significant between-group effects. Yet, within-group analyses revealed that while control couples showed flat trajectories in all outcomes after the 4-year-9-months baseline, couples receiving a third MC (at Year 5) reported small to medium improvements in three measures of relationship functioning and maintained follow-up effect in one measure. Findings indicate that couples who initially improved from the MC can maintain some of their improvements over long periods. The potential of boosting such improvements with recurrent MCs is a relevant target for further investigation in larger samples. 相似文献

Multifamily therapy (MFT) is a psychotherapeutic group intervention for patients with severe mental disorders (SMDs) and their families. The present study is a multicenter, randomized, and controlled trial that analyzes the benefit of MFT during outpatient treatment. The recruited patients were randomly assigned to the experimental group (n = 26), which received 24 MFT sessions in addition to their treatment as usual (TAU), or to the control group (n = 29), which received only TAU (individual and family sessions). Six months after the inclusion in the MFT, the experimental group showed a significant decrease in number of visits to the psychiatric emergency services, number of psychiatric admissions, and the days of admission. The need for hospital care 6 months after recruitment was also lower in the experimental group compared to the control group. These results suggest that the implementation of MFT during outpatient treatment facilitates community management of people diagnosed with mental health problems. 相似文献

Development is complex. It encompasses interacting domains, at multiple levels, across nested time scales. Embracing the complexity of development—while addressing the challenges inherent to studying infants—requires researchers to make tough decisions about what to study, why, how, where, and when. My own view is inspired by a developmental systems approach, and echoed in Esther Thelen's (2005) mountain stream metaphor. Like a river that carves its course, the active infant navigates the social and physical environment and generates rich inputs that propel learning and development. Drawing from my experiences, I offer some recommendations to guide research on infants. I encourage researchers to embrace discovery science; to observe infants in ecologically valid settings; to recognize the active and adaptive nature of infant behavior; to break down silos and consider the nonobvious; and to adopt full transparency in all aspects of research. I draw on cascading influences in infant play, language, and motor domains to illustrate the value of a bottom-up, cross-domain, collaborative approach. 相似文献
