Preventing child abuse and neglect: a national evaluation of Parents Anonymous groups

This evaluation assessed whether participation in Parents Anonymous mutual support groups was associated with child maltreatment prevention. Parents new to groups across the United States were interviewed at baseline, one month, and six months. Using standardized scales, all parents showed improvements in some child maltreatment outcomes, risk factors, and protective factors. Parents starting out with particularly serious needs showed statistically significant improvement on every scale. Results indicated that Parents Anonymous participation contributes to child maltreatment reduction.     

Effect of child protective services system factors on child maltreatment rereporting

This study examined how child protective services (CPS) systems respond to initial and subsequent reports in the context of child maltreatment rereporting and to what extent CPS system factors are associated with the risk of rereporting after controlling for abuse type and child and family factors. This study followed 67,243 families who were reported to the CPS agencies in seven counties in Florida for child abuse and neglect over a period of 5.4 years and found that 14,218 families had one or more child maltreatment rereports. Key findings include that CPS system factors were significantly different from initial report to subsequent reports. Five CPS system factors, reporting source, contact by CPS workers, investigative level at intake, postinvestigation services, and duration ofCPS involvement were significantly associated with the risk of child maltreatment rereporting. Multivariate analyses found that CPS system factors were substantially different for three categories ofrereporting, unsubstantiated rereports, substantiated rereports, and recurrence reports. Interpretations and implications for practice are discussed.     

Improving the use of self-generated identification codes

In panel studies on sensitive topics, respondent-generated identification codes are often used to link records across surveys. However, usually a substantial number of cases are lost due to the codes. These losses may cause biased estimates. Using more components and linking the codes by the Levenshtein string distance function will reduce the losses. In a simulation study and two field experiments, the proposed procedure outperforms the methods previously applied.     

Two-stage hierarchical modeling for analysis of subpopulations in conditional distributions

In this work, we develop modeling and estimation approach for the analysis of cross-sectional clustered data with multimodal conditional distributions where the main interest is in analysis of subpopulations. It is proposed to model such data in a hierarchical model with conditional distributions viewed as finite mixtures of normal components. With a large number of observations in the lowest level clusters, a two-stage estimation approach is used. In the first stage, the normal mixture parameters in each lowest level cluster are estimated using robust methods. Robust alternatives to the maximum likelihood estimation are used to provide stable results even for data with conditional distributions such that their components may not quite meet normality assumptions. Then the lowest level cluster-specific means and standard deviations are modeled in a mixed effects model in the second stage. A small simulation study was conducted to compare performance of finite normal mixture population parameter estimates based on robust and maximum likelihood estimation in stage 1. The proposed modeling approach is illustrated through the analysis of mice tendon fibril diameters data. Analyses results address genotype differences between corresponding components in the mixtures and demonstrate advantages of robust estimation in stage 1.     

Childhood sexual experiences and adult health sequelae among gay and bisexual men: defining childhood sexual abuse

Gay and bisexual men carry the burden of HIV infections in the United States and have high rates of childhood sexual abuse that predict HIV and other health outcomes. This study examined differential effects of forced, consensual, and no childhood sexual experiences (CSE) on health outcomes among a probability sample of adult men who have sex with men (MSM). The forced sex group had the highest levels of psychological distress, substance use, and HIV risk. There were no differences in rates of depression and suicidal ideation between the consensual- and no-sex groups. The consensual- and forced-sex groups had higher rates of substance use and transmission risk than the no-sex group. The forced-sex group, however, had significantly higher rates of frequent drug use and high-risk sex than the consensual group. Findings suggest that forced CSEs result in a higher-risk profile than consensual or no childhood sexual experiences, the kind of risk pattern differs between forced and consensual childhood sexual experiences, and the underlying mechanisms that maintain risk patterns may vary. It is important to clarify risk patterns and mechanisms that maintain them differentially for forced and consensual sex groups so that interventions may be tailored to the specific trajectories related to each experience.     

The contribution of media consumption to civic participation

A national UK survey (N = 1017) examined the association between media consumption and three indicators of civic participation - likelihood of voting, interest in politics, and actions taken in response to a public issue of concern to the respondent. Multiple regression analysis was used to test the variance explained by media use variables after first controlling for demographic, social and political predictors of each indicator of participation. Media use significantly added to explaining variance in civic participation as follows. In accounting for voting, demographic and political/social factors mattered, but so too did some media habits (listening to the radio and engagement with the news). Interest in politics was accounted for by political/social factors and by media use, especially higher news engagement and lower media trust. However, taking action on an issue of concern was accounted for only by political/social factors, with the exception that slightly fewer actions were taken by those who watched more television. These findings provided little support for the media malaise thesis, and instead were interpreted as providing qualified support for the cognitive/motivational theory of news as a means of engaging the public.
