In 1997, the Office of Child Support Enforcement initiated the State Child Access and Visitation (AV) Grant Program, which involves annual awards of $10 million to states to promote the development of programs to alleviate access problems. Telephone interviews with 970 parents who used mediation, parent education, and supervised visitation programs funded by AV grants in nine states revealed that the programs are reaching diverse groups of parents including many low-income, non-White, and unmarried parents who receive no other type of access assistance. The programs also appear to be achieving the major objectives posited for them by the federal government. One-third to one-half of noncustodial parents in every program type reported that parent–child contact increased following program participation, with supervised visitation users who typically had the lowest levels of parent–child contact reporting a significant increase in the number of days of contact. A review of child support records for 173 program users in three states revealed that child support payments increased among participants following program participation, especially for never-married parents who paid a significantly higher proportion of what they owed. These findings are similar to results reported in a five-state study of mediation programs funded by AV grants that was conducted by the Office of the Inspector General. However, both studies have some serious limitations, including low response rates and the absence of a nontreatment comparison group.  相似文献

This study uses a structured vignette procedure to assess competency to make treatment decisions in two groups of adolescents, one at risk for institutional placement and the other a matched community sample. Scores on Factual Understanding (the ability to recall facts), Inferential Understanding (the ability to make inferences about those facts), and Reasoning (the ability to weigh risks and benefits of various treatment options and to make choices based on that reasoning) were compared. Results showed that while at-risk adolescents and their community, counterparts did not differ in their factual and inferential understanding abilities, the at-risk adolescents did significantly less well than the community adolescents in reasoning. This difference could not be fully explained by differences in verbal IQ. Girls, no matter what their risk status, scored higher than boys on the Reasoning scale. Implications for legal policies concerning adolescents are discussed.  相似文献
