ABSTRACT

With the rapid growth in incarceration in the United States over the past few decades came dramatic growth in the number of the incarcerated parents with at least one minor child. Parental incarceration places extra stresses and strains on families and children. Almost all of those incarcerated will eventually be released. However, the majority of those released from prison will be rearrested within a year. Finding interventions that can decrease the likelihood of returning to crime and to incarceration are of utmost importance. Using a social bond theory framework, the authors examine the moderating effect of living with a child before incarceration on program outcomes related to a prison-based parent management training program. A significant effect was found. Implications for these findings are discussed for future research and practice.  相似文献

Indigenous children and young people are over‐represented at all stages of the Australian child protection system. Policy and legislative initiatives exist in the state of Victoria, Australia aiming to support the connection between Indigenous children and young people in state care and their culture and community. This exploratory research involved focus group consultations with seven child and family welfare agencies to investigate the impacts, barriers, benefits and limitations of cultural support planning for Indigenous young people in, and leaving care in, Victoria. Findings indicated that cultural planning was of value when it could be completed. However, various shortcomings of current systems were identified including limited resourcing of Aboriginal Community Controlled Organisations to generate plans and provide direct and secondary consultation services to implement plans, difficulty gathering information for plans and some Indigenous young people expressing disinterest in connecting to their culture and community. Complexities in the relationships between the Indigenous and non‐Indigenous agencies that aimed to support Indigenous young people in care were also acknowledged. Participants identified a number of strategies to improve outcomes, such as facilitating better relationships between agencies, promoting opportunities for ongoing cultural training for staff in mainstream agencies and improving the resourcing of Aboriginal Community Controlled Organisations to deliver planning and to support cultural connections.  相似文献

Objective: The purpose of this pilot study was to evaluate the Resilience and Coping Intervention (RCI) with college students. Participants: College students (aged 18–23) from a large Midwest US university who volunteered for a randomized controlled trial during the 2015 spring semester. Methods: College students were randomly assigned to an intervention (n = 64) or a control (n = 65) group. Intervention participants received three 45-minute RCI sessions over subsequent weeks. All participants completed pre- and post-intervention assessments at the beginning of Week 1 and end of Week 3. Student resilience, coping, hope, stress, depression, and anxiety were assessed. Results. RCI participants reported significantly more hope and less stress and depression from Week 1 to Week 3 compared with control participants. Results for resilience also approached statistical significance. Effect sizes were small to moderate. Conclusions: This study found preliminary evidence that RCI is an effective resilience intervention for use with college students.  相似文献

Middle school is the appropriate time for students to begin exploring careers and improving self‐efficacy; however, empirically supported career and college readiness interventions for U.S. middle school students are limited. Examining the effect of an intervention that combined a virtual experience and a local college visit on middle school students (99 girls, 74 boys), the authors found that participating students had higher levels of college and career self‐efficacy than did nonparticipating students. The study shows that a workshop of the online Florida CHOICES program coupled with a campus visit increased middle school student career and college self‐efficacy. Future research should include longitudinal studies and use of diverse populations to improve generalizability of study results.  相似文献

We examine a recent dispute regarding the Centers for Medicare and Medicaid Services’ (CMS) refusal to unconditionally pay for amyloid positron emission tomography (PET) imaging for Medicare beneficiaries being assessed for Alzheimer’s disease. CMS will only pay for amyloid PET imaging when patients are enrolled in clinical trials that meet certain criteria. The dispute reflects CMS’s willingness in certain circumstances to require effectiveness evidence that differs from the Food and Drug Administration’s standard for pre-market approval of a medical intervention and reveals how stakeholders with differing perspectives about evidentiary standards have played a role in attempting to shape the Medicare program’s coverage policies.  相似文献
