Over the past four to five decades, multiple randomized controlled trials have verified that preventive interventions targeting key parenting skills can have far-reaching effects on improving a diverse array of child outcomes. Further, these studies have shown that parenting skills can be taught, and they are malleable. Given these advances, prevention scientists are in a position to make solid empirically based recommendations to public child service systems on using parent-mediated interventions to optimize positive outcomes for the children and families that they serve. Child welfare systems serve some of this country’s most vulnerable children and families, yet they have been slow (compared to juvenile justice and mental health systems) to adopt empirically based interventions. This paper describes two child-welfare-initiated, policy-based case studies that have sought to scale-up research-based parenting skills into the routine services that caseworkers deliver to the families that they serve. In both case studies, the child welfare system leaders worked with evaluators and model developers to tailor policy, administrative, and fiscal system practices to institutionalize and sustain evidence-based practices into usual foster care services. Descriptions of the implementations, intervention models, and preliminary results are described. © 2017, Springer Science+Business Media New York.

The target article is a qualitative review of selected findings in the physical attractiveness literature. This commentary explains why the meta-analytic approach, frequently used by other attractiveness reviewers, is preferable for drawing unbiased conclusions about the effects of attractiveness. The article's main contribution is affording a foundation for subsequent meta-analysis of the studies discussed in a subjective fashion. © Cambridge University Press 2017.

While it is well known that working memory functions decline with age, the functional reasons for this decline are not well understood. A factor that has proven critical for general individual differences in visual working memory capacity is the efficiency of filtering irrelevant information. Here, we examine to what degree this factor is also responsible for age differences in working memory. Young and old participants performed a change-detection task where some items in the encoding display were marked as irrelevant. The contralateral delay activity of the electroencephalogram was used to assess individual participants' filtering efficiency (see Vogel EK, McCollough AW, Machizawa MG. 2005. Neural measures reveal individual differences in controlling access to working memory. Nature. 438:500-503.). Older adults showed smaller filtering scores than young adults, but only early in the retention interval, suggesting that efficient filtering was delayed. In contrast, age-independent individual differences in filtering were reflected primarily later in the retention interval. Thus, age and individual differences in filtering are reflected in different ways showing that old adults are not simply like less efficiently performing young adults. © The Author 2010.

Adolescent psychopathology is commonly connected to marijuana use. How changes in these adolescent antecedents and in adolescent marijuana use are connected to patterns of marijuana use in the 20s is little understood. Another issue not clearly understood is psychopathology in the 30s as predicted by marijuana use in the 20s. This study sought to examine these two issues and the associations with marijuana disorder diagnoses using a longitudinal data set of 205 men with essentially annual reports. Individual psychopathology and family characteristics from the men's adolescence were used to predict their patterns of marijuana use across their 20s, and aspects of the men's psychopathology in their mid-30s were predicted from these patterns. Three patterns of marijuana use in the 20s were identified using growth mixture modeling and were associated with diagnoses of marijuana disorders at age 26 years. Parental marijuana use predicted chronic use for the men in adulthood. Patterns of marijuana use in the 20s predicted antisocial behavior and deviant peer association at age 36 years (controlling for adolescent levels of the outcomes by residualization). These findings indicate that differential patterns of marijuana use in early adulthood are associated with psychopathology toward midlife. © 2014 Cambridge University Press.

Objective: Multilevel and latent growth models are frequently used interchangeably to examine differences between groups in trajectories of outcomes from controlled clinical trials. The unstandardized coefficient for the effect from group to slope (the treatment effect) from such models can be converted to a standardized mean difference (Cohen's d) between the treatment and control groups at end of study. This article addresses the confidence interval (CI) for this effect size. Method: Two sets of equations for estimating the CI for the treatment effect size in multilevel models were derived, and the usage of each was illustrated with data from the National Youth Study (Elliott, Huizinga, & Menard, 1989). Validity of the CIs was examined with a Monte Carlo simulation study that manipulated effect potency and sample size. Results: The equivalence of the 2 new CI estimation methods was demonstrated, and the Monte Carlo study found that bias in the CI for the effect size was not appreciably larger than bias in the CI for the widely used unstandardized coefficient. Conclusions: Investigators reporting this increasingly popular effect size can estimate its CI with equations presented in this article. © 2014 American Psychological Association.

In this study, the validity of a self-report measure of children's perceived attachment security (the Kerns Security Scale) was tested using adolescents. With regards to predictive validity, the Security Scale was significantly associated with (1) observed mother-adolescent interactions during conflict and (2) parent- and teacher-rated social competence. With regards to convergent validity, the Security Scale was significantly associated with all subscales of the Adult Attachment Scale (i.e., Depend, Anxiety, and Close) as measured 3 years later. Further, these links were found even after controlling for mother-child relationship quality as assessed by the Inventory of Parent and Peer Attachment (IPPA), and chi-square difference tests indicated that the Security Scale was generally a stronger predictor as compared to the IPPA. These results suggest that the Security Scale can be used to assess perceived attachment security across both childhood and adolescence, and thus could contribute significantly to developmental research during this period. © 2011 The Foundation for Professionals in Services for Adolescents.

Objective: This study evaluated the ability of delinquent peer affiliation to mediate the effects of multidimensional treatment foster care (MTFC; Chamberlain, 2003) on girls' delinquent behavior. Method: This study used a sample of girls from 2 cohorts (N = 166; M = 15.31 years old at baseline, range 13-17 years; 74% European American, 2% African American, 7% Hispanic, 4% Native American, 1% Asian, and 13% mixed ethnicity) and measures of delinquent behavior, including general delinquency, number of criminal referrals, and number of days in locked settings. As the mediator, we used self-reports of affiliation with delinquent peers. Our analytic plan specified an intent-to-treat analysis within the framework of a randomized controlled trial comparing MTFC with traditional community-based group care. Results: Random assignment to the MTFC program reduced girls' number of criminal referrals and number of days in locked settings at 24 months. The MTFC condition also reduced girls' exposure to delinquent peers at 12 months, which in turn reduced levels of all forms of delinquent behavior at 24 months; indirect effects were statistically significant. Conclusions: Reduction in exposure to delinquent peers mediated MTFC effects on the number of criminal referrals and number of days in locked settings; delinquent peers also served as an intervening variable between MTFC and self-report delinquency, suggesting that, by reducing contact with delinquent peers, MTFC helped to encourage lower levels of self-report delinquency. Existing prevention and intervention programs targeting similar populations may benefit from increased attention to reductions in delinquent peer affiliation in female samples. © 2012 American Psychological Association.

Objective: The present study evaluated the efficacy of the Middle School Success intervention (MSS) for reducing substance use and delinquency among girls in foster care, using a randomized controlled trial design. The program was designed to fill a service gap during the summer prior to the middle school transition and to prevent delinquency, substance use, and related problems. Method: One hundred girls in foster care and their caregivers were randomly assigned either to the intervention (n = 48) or to a regular foster care control (n = 52) condition. The girls completed a baseline (T1) assessment and follow-up assessments at 6 months (T2), 12 months (T3), 24 months (T4), and 36 months (T5) postbaseline. Caregivers participated in assessments from T1 through T4. This study is a follow-up to Smith, Leve, and Chamberlain's (2011) study, which examined immediate outcomes at T2. Results: Girls in the intervention condition showed significantly lower levels of substance use than did girls in the control condition at 36 months postbaseline. The group difference was only marginally significant for delinquency. Further analyses indicated significant indirect effects of the intervention through increased prosocial behaviors that led to decreased internalizing and externalizing symptoms and then to lower levels of substance use. The direct effect of the intervention on substance use remained significant in the presence of the indirect effects. For delinquency, the intervention had positive effects mainly through increased prosocial skills. Conclusions: Findings highlight the importance of providing preventive intervention services for early adolescent girls in foster care. © 2011 American Psychological Association.

Implementation Science | Year: 2014

Background: This protocol describes the 'development of outcome measures and suitable methodologies for dissemination and implementation approaches,' a priority for implementation research. Although many evidence-based practices (EBPs) have been developed, large knowledge gaps remain regarding how to routinely move EBPs into usual care. The lack of understanding of 'what it takes' to install EBPs has costly public health consequences, including a lack of availability of the most beneficial services, wasted efforts and resources on failed implementation attempts, and the potential for engendering reluctance to try implementing new EBPs after failed attempts.The Stages of Implementation Completion (SIC) is an eight-stage tool of implementation process and milestones, with stages spanning three implementation phases (pre-implementation, implementation, sustainability). Items delineate the date that a site completes implementation activities, yielding an assessment of duration (time to complete a stage), proportion (of stage activities completed), and a general measure of how far a site moved in the implementation process.Methods/Design: We propose to extend the SIC to EBPs operating in child service sectors (juvenile justice, schools, substance use, child welfare). Both successful and failed implementation attempts will be scrutinized using a mixed methods design. Stage costs will be measured and examined. Both retrospective data (from previous site implementation efforts) and prospective data (from newly adopting sites) will be analyzed. The influence of pre-implementation on implementation and sustainability outcomes will be examined (Aim 1). Mixed methods procedures will focus on increasing understanding of the process of implementation failure in an effort to determine if the SIC can provide early detection of sites that are unlikely to succeed (Aim 2). Study activities will include cost mapping of SIC stages and an examination of the relationship between implementation costs and implementation performance (Aim 3).Discussion: This project fills a gap in the field of implementation science by addressing the measurement gap between the implementation process and the associated costs. The goal of this project is to provide tools that will help increase the uptake of EBPs, thereby increasing the availability of services to youth and decreasing wasted resources from failed implementation efforts. © 2014 Saldana; licensee BioMed Central Ltd.

To better understand quantity and quality of divorced father contact, a weighted county sample of 230 divorced fathers with a child aged 4-11 years was employed to test whether fathers' antisocial personality (ASP) moderated effects of monthly contact with children in predicting children's observed noncompliance. Eighteen-month latent growth models obtained significant individual differences in levels of noncompliance and growth rates. ASP significantly moderated beneficial impact of fathers' monthly contact. Fathers' observed parenting practices significantly predicted noncompliance levels but not growth. Parenting did not account for the effect of Contact × ASP, suggesting both environmental and potentially genetic influences on child adjustment. Findings were robust across boys and girls and age levels. Implications for preventive intervention are discussed. © 2010, the Author(s).
