OBJECTIVE: To determine factors influencing outpatient mental health service use by children in foster care. METHOD: Detailed survey and administrative data were collected on 480 children who entered long-term foster care in San Diego County from May 1990 through October 1991. These data were linked with claims data from Medicaid and San Diego County Mental Health Services information systems. A Poisson regression model was used to determine whether the following factors influenced outpatient mental health service use: age, race/ethnicity, gender, maltreatment history, placement pattern, and behavioral problems as measured by the Achenbach Child Behavior Checklist (CBCL). RESULTS: Except for maltreatment history, all independent variables included in the multivariate regression model were statistically significant. The total number of outpatient mental health visits increased with age, male gender, and non-relative foster placements. Relative to Caucasians, visits were lower for Latinos, and Asian/Others, but comparable for African-Americans. Concerning maltreatment history, differences were only found in one category; children experiencing caretaker absence received fewer visits compared to children who did not experience caretaker absence. Children with CBCL Total Problem Scale T-scores of 60 or greater had significantly more visits than those with a score less than 60. CONCLUSIONS: Both clinical and non-clinical factors influence outpatient mental health service use by foster children. Limitations imposed by gender, race/ethnicity, and placement setting need to be addressed by child welfare policies. These finding suggest that guidelines are needed to systematically link children in foster care with behavioral problems to appropriate services. 相似文献

This study compares the impact of Anglican voluntary aided and voluntary controlled schools on a range of indices of local church life throughout the diocese of Chelmsford. After controlling for the influence of population size, the church electoral roll, the age of the priest in charge of the benefice, the number of churches in the benefice, and the number of stipendiary clergy employed in the benefice, the data lead to two conclusions. Voluntary controlled primary schools have no significant impact on any of the indices of local church life included in the study. Voluntary aided primary schools are associated with a significantly higher level of pre-teenage confirmands, but they have no influence on the number of older confirmands, the number of baptisms, the usual Sunday church attendance, or the number of festival communicants. 相似文献

OBJECTIVE: This study examines the unique contribution of five types of maltreatment (sexual abuse, physical abuse, emotional abuse, physical neglect, emotional neglect) to adult health behaviors as well as the additive impact of exposure to different types of childhood maltreatment. METHOD: Two hundred and twenty-one women recruited from a VA primary care clinic completed questionnaires assessing exposure to childhood trauma and adult health behaviors. Regression models were used to test the relationship between childhood maltreatment and adult health behaviors. RESULTS: Sexual and physical abuse appear to predict a number of adverse outcomes; when other types of maltreatment are controlled, however, sexual abuse and physical abuse do not predict as many poor outcomes. In addition, sexual, physical, and emotional abuse and emotional neglect in childhood were all related to different adult health behaviors. The more types of childhood maltreatment participants were exposed to the more likely they were to have problems with substance use and risky sexual behaviors in adulthood. IMPLICATIONS: The results indicate that it is important to assess a broad maltreatment history rather than trying to relate specific types of abuse to particular adverse health behaviors or health outcomes. 相似文献

Environmental and Genetic Variance in Children's Observed and Reported Maladaptive Behavior 总被引:1,自引:0,他引:1

The genetic and environmental contributions to children's maladaptive behavior are assessed in a sample of 154 twin pairs (77 MZ twin pairs and 77 DZ twin pairs), who range in age from 6 to 11 years. To bridge the strengths of behavioral genetic methods and environmental assessment techniques, we use a multimethod, multimeasure approach to data collection, and analyze the data using behavioral genetic modeling techniques. Results indicate that genetic variation accounts for a majority of the variance in parent-reported child maladaptive behavior (average = 62%). One parent-report measure also suggests a smaller, significant contribution of shared environmental variance. In contrast to the parental ratings, the observational coding and global impressions of parent-twin interactive behavior suggest that shared environment is the primary source of variance accounting for parent and child maladaptive behavior. This is due, in part, to the direct influence one's interactive partner has on the expression of maladaptive behavior in an interactive setting. When controlling for the co-participant's behavior, genetic variation increases and shared environmental variation decreases. 相似文献

There are no panaceas and no shortcuts. Man is an amphibious being who lives simultaneously or successively in several universes:
in the world of matter, the world of mind, the world of spirit; in the individual world and in the social world; in the homemade
universe of his own artifacts, institutions, and imaginings, and in the given, the God-made universe of nature and grace.
In the very nature of things none of the major problems confronting such a being can possibly be a simple problem. Those who
seek simple solutions for complex problems may have the best of intentions; but unfortunately there is an original sin of
the intellect in our habit of arbitrary oversimplification. Those who act without taking precautions against this vice of
their intellectual nature doom themselves and their fellows to perpetual disappointment. (Aldous Huxley, 1953, p. 1.) 相似文献

This study examined two possible mechanisms, evocative gene–environment correlation and prenatal factors, in accounting for child effects on parental negativity. Participants included 561 children adopted at birth, and their adoptive parents and birth parents within a prospective longitudinal adoption study. Findings indicated child effects on parental negativity, such that toddlers’ negative reactivity at 18 months was positively associated with adoptive parents’ over-reactive and hostile parenting at 27 months. Furthermore, we found that child effects on parental negativity were partially due to heritable (e.g., birth mother [BM] internalizing problems and substance use) and prenatal factors (e.g., BM illicit drug use during pregnancy) that influence children’s negative reactivity at 18 months. This study provides critical evidence for “child on parent” effects. 相似文献

Abstract This article examines the ways in which the narrative or story form generates personal connections between visitors and content and thus is ideally suited to the work of museums. Starting with a review of the qualities of narrative, the article provides specific examples of how stories and storytelling have worked in exhibitions, public programs and outreach to schools. 相似文献

Capillary wave phenomena are challenging to study, especially for microfluidics where the wavelengths are short, the frequencies are high, and the frequency distribution is rarely confined to a narrow range, let alone a single frequency. Those that have been studying Faraday capillary waves generated by vertical oscillation have chosen to work at larger scales and at low frequencies as a solution to this problem, trading simplicity in measurement for issues with gravity, boundary conditions, and the fidelity of the subharmonic capillary wave motion. Laser Doppler vibrometry using a Mach–Zehnder interferometer is an attractive alternative: The interface’s motion can be characterized at frequencies up to 40 MHz and displacements of as little as a few tens of picometers. 相似文献
