This study examined specific parenting practices as predictors of prospective levels of children’s hyperactivity/inattention across early- and middle-childhood. Participants were a mixed-sex community cohort (N?=?976; 52 % boys) aged 4–10 years (M?=?6.5, SD?=?1.3). Measures of parenting practices, hyperactivity/inattention, conduct problems, and maternal education were collected at baseline, and hyperactivity/inattention re-assessed at 12-month follow-up. Analyses examined predictors of 12-month hyperactivity/inattention while controlling for levels at baseline. High levels of parental involvement were associated with reduced levels of hyperactivity/inattention, but only across early childhood. Conversely, increases in child age were associated with increased levels of hyperactivity/inattention across middle-childhood, but only among children exposed to high levels of inconsistent discipline. Inconsistent discipline and parental involvement appear to be uniquely associated with prospective hyperactivity/inattention across childhood, independent of associated conduct problems. Our results further suggest some developmental specificity with regard to the effects of these distinct dimensions of parenting on hyperactivity/inattention at different points in childhood.  相似文献

This study tested the potential to elicit a broadened attentional focus through writing about a positive life experience and to derive health benefits from such writing. Participants (n = 38) wrote for 20 min each day for 3 consecutive days about either a positive life experience or a control topic. Writing about positive experiences led to improved physical health (measured 4–6 weeks after writing) compared to control and higher levels of global cognitive focus after writing mediated this effect. Notably, while the positive writing condition was more broadened than control, positive affect was not responsible for this difference. Implications for disclosive writing and the broaden and build model are discussed.  相似文献

The Rey Auditory Verbal Learning Test was utilized to examine attention, learning, and memory abilities in 42 children with cerebellar (N?=?18) and third ventricle tumors (N?=?24). Children with cerebellar tumors exhibited significant auditory attentional impairments and displayed adequate encoding and retrieval across subsequent learning and memory trials. In contrast, children with third ventricle tumors exhibited average auditory attentional abilities, but they displayed mild encoding deficits across trials 2–5. Furthermore, the third ventricle group's compromised performance on the delayed recall trial and average performance on the delayed recognition trial is suggestive of underlying retrieval deficits.  相似文献

Introduction: Effective brief psychological approaches for depression that can be delivered by a variety of health professionals with minimal training increase access to treatment by patients. Problem Solving Treatment (PST) was developed for primary care and was modified for this study (EPST) to better meet the needs of mental health patients. Method: A total of 92 therapists from different professional backgrounds completed EPST workshops and treated 92 patients with major depression with interval clinical and treatment process assessments. Results: EPST achieved a significant reduction in depressive symptom scores, life problem scores, and there were few treatment non‐completers. Treatment outcome was predicted by process and therapist variables. Discussion: EPST is an effective and easy to teach treatment that can be delivered by a variety of practitioners and suitable for busy primary mental health care settings.  相似文献

Abstract

Using human embryos in research remains a controversial issue, especially in Christian bioethics. Although the official Catholic stance rejects human embryonic stem cell research, Christian thinkers T. Peters, K. Lebacqz and G. Bennett support it. They endorse the 14-day Rule and argue that ex vivo embryos lack moral worth. I examine and challenge the 14-day Rule and location argument (in vivo/ex vivo). I develop a theory of holistic anthropology and intrinsic moral value for human embryos. I conclude that intrinsic moral value is not equal to full moral value, and therefore use of embryos in biomedical research is morally permissible.  相似文献

Challenged by Lynn White's sharp criticism of Christianity's responsibility for earth's ecological crisis, both Ian Barbour and Philip Hefner have proposed theological anthropologies based upon the imago Dei that supports an ecological ethic. Russell, while supporting the ecological ethic, turns not to anthropology but rather to eschatology and the proleptic vision of a new creation.  相似文献
