Objectives

This study examined the effects of individual and contextual factors on reentry into out-of-home care among children who were discharged from child protective services in fiscal year 2004-2005. The objectives were to: (1) examine individual and contextual factors associated with reentry, (2) explore whether there are meaningful groups of youth who differ in terms of risk for reentry, and (3) determine whether relatively homogeneous clusters of child welfare agencies, based on contextual characteristics, differ significantly in terms of the reentry rates of the children whom they serve.

Method

The study design involved a multilevel longitudinal analysis of administrative data based on an exit cohort. Two Cox proportional hazards multilevel mixture models were tested. The first model included multiple individual level predictors and no agency level predictors. The second model included both levels of predictors.

Results

The results of multilevel Cox regression mixture modeling indicated that at the individual level, younger age, being placed in out-of-home care because of neglect and having physical, health problems corresponded to a decreased likelihood for reentry. At the agency level, lower average expenditures per child and contracting out case management services were associated with faster reentry into out-of-home care.

Conclusions

This study demonstrates that children who reenter out-of-home care appear to be a homogeneous population and that reentry is associated with both contextual factors and individual characteristics.

Practice implications

The most important implication that can be drawn from the study findings is that reentry may be most effectively prevented by focusing on such factors at the organizational level as contracting out case management services and funding allocation. Child welfare agencies that are responsible for an array of services and decide to contract out case management should consider the use of performance-based contracts and emphasize and strengthen quality assurance approaches for contracted services. In addition, to compensate for lower funding allocated for children served in out-of-home care, child welfare workers should become more familiar with community resources and help connect families to these supports.  相似文献

The writing skills of 286 children (157 female and 129 male) were studied by comparing name writing and letter writing scores from preschool to kindergarten with letter and word reading scores over the same time period. Two rubrics for scoring writing were compared to determine if scores based on multiple components (i.e., letter formation, orientation on the vertical axis, left–right orientation, and correct letter sequencing) would better reflect differences in children’s writing knowledge in preschool and kindergarten than rubrics composed of one component (i.e., letter formation only). While developmental changes in writing scores were found, little additional information was provided by multiple component scoring rubrics compared to the single component rubric. Letter writing scores were more strongly related to letter and word reading scores than name writing scores but neither writing score was predictive of growth. Implications of the findings for intentional/systematic writing instruction in preschool curricula are discussed.  相似文献

The relation of attachment security to multiple domains of psychosocial functioning was examined in a community sample of 167 early adolescents. Security of attachment organization, assessed using the Adult Attachment Interview, was linked to success in establishing autonomy while maintaining a sense of relatedness both with fathers and with peers, even after accounting for predictions from qualities of the mother-teen relationship. Growth curve analyses revealed links of insecurity to increasing patterns of externalizing behavior and higher and stable patterns of depressive symptoms across adolescence. Implications for a developing theory of the connections of the attachment system to multiple domains of functioning in adolescence are discussed.  相似文献

Using the stereotype content model as a guiding framework, this study explored whether the stigma that able‐bodied adults have towards children with a physical disability is reduced when the child is portrayed as being active. In a 2 (physical activity status) x 2 (ability status) study design, 178 university students rated a child described in one of four vignettes on 12 dimensions of perceived warmth and competence. Results revealed a main effect of ability status on warmth (p < 0.001) such that children with a physical disability were rated significantly higher in perceived warmth than able‐bodied children, regardless of activity status (d = 0.86). Also, there was a significant interaction (p = 0.02) of ability and activity status on perceived competence, indicating that ratings of perceived competence were significantly higher for active children with a physical disability than for all other children (d = 0.54–0.64). Results suggest that physical activity should be explored as a way to mitigate the stigmatisation of children with a physical disability.  相似文献

Although it remains rare in the United States, planned home birth has drawn increasing attention and criticism in the mainstream media and has come under attack from organized medicine. Yet, recent peer-reviewed studies contribute to the evidence base supporting home birth as a safe option for low-risk women attended by skilled midwives. The author of this editorial argues that home birth is an important cultural touchstone in the landscape of American maternity care.  相似文献
