Our study represents a rural case management agency's use of its data to aid in its transition from being funded by federal grant funds to self-sustainment. We wanted to learn if some characteristics of those children served could predict the resources needed to serve them. We analyzed data on 90 children and adolescents living in a rural community. Using multiple regression analysis we found that CAFAS total and CBCL total problem scores predicted Medicaid reimbursements but not flexible funds spending or case management hours. History of psychiatric hospitalization, however, predicted flexible funds spending and case management hours. Using one-way ANOVA and post hoc analysis we found that the staff members' assessments of each child and family's level of service needs were reflected in differences in mean CAFAS total scores, Medicaid reimbursements and case management hours, but not CBCL total problem scores or flexible funds spending. 相似文献

We report associations between serial measures of blood lead and intelligence in children age 10-12 years, half heavily exposed to lead from the prenatal period onward, and half relatively unexposed. For a subsample, we examine bone lead-IQ associations, comparing them with bone lead associations. Both blood and bone lead levels were associated with intelligence decrements, small relative to the contribution of social factors. For each doubling of Tib-Pb, Full Scale, Performance, and Verbal IQ decreased by an estimated 5.5, 6.2, and 4.1 points, respectively. Bone lead-IQ associations were stronger than those for blood lead, which nonetheless provide robust analogues. Current BPb, easy to obtain, provides a useful means for assessing Pb exposure/IQ associations. 相似文献

This study explores associations of IQ at age 14 with adult symptoms of suicidal thoughts and attempts at age 21. Analysis was based on the Mater University Study of Pregnancy and its outcomes, an Australian prospective birth cohort study started in Brisbane Australia in 1981. We assessed associations with suicide thoughts, plans, and attempts. We used two measures of IQ: the Raven's Standard Progressive Matrices and the Wide Range Achievement Test. In multivariable analyses, there was an inverse association between Raven's IQ and suicide thoughts, plans, and attempts, but no strong evidence of an association between the WRAT3 and the three suicidal items. Specific aspects of intelligence may be associated with suicidal thoughts, plans, and attempts. 相似文献

Despite the considerable literature that documents the existence of a positive relationship between religious faith and individual well-being, there has been little investigation of the mechanisms by which this connection operates. An investigation of this issue, using qualitative research methods and based on classical and contemporary sociological theory, suggests that Christian faith provides its adherents with several tools with which they can combat those circumstances in their lives that are likely to lead to distress and disease. These tools include community, hope, meaning systems, behavioral constraints, and elements of church practice and church life, all of which work together to provide the faithful with a sense of peace that contributes to their well-being. 相似文献

Some problems inherent in administering inhalation anesthetics to small laboratory animals in studies of memory consolidation are discussed. A simple and inexpensive apparatus which has been designed to eliminate some of these problems is described. 相似文献

Two experiments are reported in which subliminal stimulation of one modality with emotional material impairs detection performance in a different modality. In the first experiment the visual awareness threshold for neutral material was raised by simultaneous auditory presentation of emotional words. This result supports the hypothesis that threshold changes induced by emotional stimulation are mediated centrally. In the second experiment a similar effect was obtained when the experimental roles of the two modalities were reversed. An analysis of the effect in terms of the parameters of Signal Detectability Theory indicates that it is mediated by a lowering of the sensitivity of the detection mechanism. This may be caused either by attenuation of incoming signals, or by an increase in the level of “noise” against which the signal is received. 相似文献
