AbstractExisting research on the impact of growing up in care focuses upon either the care experience itself or the period of transition from care to independence. Our knowledge of outcomes largely ceases when former residents of the care system reach their early twenties. There are strong social justice reasons for extending research into the older adult lives of such young people. We know a great deal about the multiple disadvantages that such individuals face as children. But research is largely silent about their subsequent adult lives. While we must be cautious in drawing causal links to the childhood care experience as the time period since life in care extends, we know that early experiences can affect care-leavers across their life course—just as childhood experience affects all adults in a variety of ways. In this review, we highlight evidence drawn from research in Australia, the United Kingdom, Canada, Ireland, and the United States, with particular attention paid to the first two of those countries. We use a wide range of sources and identify areas for further consideration, including access to personal records, mental health, education, and parenting. By doing so, we seek to open up this area for further research with the hope that such research will lead to an increasing recognition of care-leavers' needs and thus to improvements in social policy and service provision. 相似文献

To identify Gambling Disorder (GD) subtypes, in a population of men seeking treatment for GD, according to specific executive function domains (i.e., cognitive flexibility, inhibition and working memory as well as decision making) which are usually impaired in addictive behaviors. A total of 145 males ranging from 18 to 65 years diagnosed with GD were included in this study. All participants completed: (a) a set of questionnaires to assess psychopathological symptoms, personality and impulsivity traits, and (b) a battery of neuropsychological measures to test different executive functioning domains. Two clusters were identified based on the individual performance on the neuropsychological assessment. Cluster 1 [n = 106; labeled as Low Impaired Executive Function (LIEF)] was composed by patients with poor results in the neuropsychological assessment; cluster 2 patients [n = 46; labeled as High Impaired Executive Function (HIEF)] presented significantly higher deficits on the assessed domains and performed worse than the ones of LIEF cluster. Regarding the characterization of these two clusters, patients in cluster 2 were significantly older, unemployed and registered higher mean age of GD onset than patients in cluster 1. Additionally, patients in cluster 2 also obtained higher psychopathological symptoms, impulsivity (in both positive and negative urgency as well as sensation seeking) and some specific personality traits (higher harm avoidance as well as lower self-directedness and cooperativeness) than patients in cluster 1. The results of this study describe two different GD subtypes based on different cognitive domains (i.e., executive function performance). These two GD subtypes display different impulsivity and personality traits as well as clinical symptoms. The results provide new insight into the etiology and characterization of GD and have the potential to help improving current treatments. 相似文献

Most individuals will gamble during their lifetime, yet only a select few will develop gambling disorder. Gray’s Reinforcement Sensitivity Theory holds promise for providing insight into gambling disorder etiology and symptomatology as it ascertains that neurobiological differences in reward and punishment sensitivity play a crucial role in determining an individual’s affect and motives. The aim of the study was to assess a mediational pathway, which included patients’ sex, personality traits, reward and punishment sensitivity, and gambling-severity variables. The Sensitivity to Punishment and Sensitivity to Reward Questionnaire, the South Oaks Gambling Screen, the Symptom Checklist-Revised, and the Temperament and Character Inventory-Revised were administered to a sample of gambling disorder outpatients (N = 831), diagnosed according to DSM-5 criteria, attending a specialized outpatient unit. Sociodemographic variables were also recorded. A structural equation model found that both reward and punishment sensitivity were positively and directly associated with increased gambling severity, sociodemographic variables, and certain personality traits while also revealing a complex mediational role for these dimensions. To this end, our findings suggest that the Sensitivity to Punishment and Sensitivity to Reward Questionnaire could be a useful tool for gaining a better understanding of different gambling disorder phenotypes and developing tailored interventions. 相似文献

The purpose of this study was to evaluate whether a 12-wk functional circuit-training program (FCT) could alter markers of physical frailty in a group of frail community-dwelling adults. Fifty-one individuals (31 women, 20 men), mean age (± SD) 84 (± 2.9) yr, met frailty criteria and were randomly assigned into groups (FCT = 26, control group [CG] = 25). FCT underwent a 12-wk exercise program. CG met once a week for health education meetings. Measures of physical frailty, function, strength, balance, and gait speed were assessed at Weeks 0, 12, and 36. Physical-frailty measures in FCT showed significant (p < .05) improvements relative to those in CG (Barthel Index at Weeks 0 and 36: 73.41 (± 2.35) and 77.0 (± 2.38) for the FCT and 70.79 (± 2.53) and 66.73 (± 2.73) for the CG. These data indicate that an FCT program is effective in improving measures of function and reducing physical frailty among frail older adults. 相似文献

A randomized prevention trial was conducted contrasting families who took part in the Strong African American Families Program (SAAF), a preventive intervention for rural African American mothers and their 11‐year‐olds, with control families. SAAF is based on a conceptual model positing that changes in intervention‐targeted parenting behaviors would enhance responsive‐supportive parent–child relationships and youths' self‐control, which protect rural African American youths from substance use and early sexual activity. Parenting variables included involvement‐vigilance, racial socialization, communication about sex, and clear expectations for alcohol use. Structural equation modeling analyses indicated that intervention‐induced changes in parenting were linked with changes in responsive–supportive parent–child relationships and youth self‐control. 相似文献

Observations were conducted in three county councils to find out whether the government’s ambition to develop Learning Disability Partnership Boards (as expressed in the White Paper Valuing people) are being realized. All the partnerships practiced various inclusive activities in order to involve people with learning disabilities in public service strategies. However, there appeared to be limited opportunities for citizens to be involved in recommendations or decision‐making for their area. This concurs with other research elsewhere on the involvement of citizens in state provision, i.e. public participation in civic affairs remains in the control of public sector managers. The lack of opportunities for citizens to direct the allocation of resources and strategies at a local level, regardless of their ability to process information, emphasises the limits of New Labour’s citizen–public sector partnerships. 相似文献

Despite the considerable resources devoted to making demographic projections in Australia over the past two decades, there have been few attempts to evaluate the performance of these projections in terms of forecast accuracy. This paper first considers the role of accuracy amongst other objectives of projection activity. Accepting accuracy as a legitimate goal, we then assess the performance of 48 sets of population projections and forecasts for states and territories of Australia prepared since 1970. Projection accuracy is assessed by reference to length of forecast horizon, population size and rate of growth. We also examine the main sources of forecast error in selected projections for each state and compare the performance of past projections with alternatives based on simple extrapolation of contemporary population trends. 相似文献

Increased contamination of the environment by toxic chemicals has resulted in the need for sensitive assays to be used in risk assessment of polluted sites. Traditional tests are useful to detect and measure concentrations of chemicals in the environment and in tissues. However, physicochemical assays possess deficiencies that impair their use in evaluating complex environmental contamination. We have developed cytogenetic procedures, including chromosomal, micronucleus, and flow cytometric assays, to assess the mutagenic damage of petrochemicals and low-level radioactivity on indigenous terrestrial and aquatic wildlife populations. These procedures are sensitive to the perturbation of DNA that results from exposure to mutagenic contaminants in both field and laboratory studies. The use of natural populations of animals in biomonitoring, combined with traditional chemical assays, will ultimately provide sufficient information to estimate the risk to human health and environmental quality from anthropogenic pollution. 相似文献
