RESUMO
Without preventative intervention, youth with a history of foster care (FC) involvement have a high likelihood of developing depression and anxiety (DA) symptoms. The current study used integrative data analysis to harmonize data across four foster and kinship parent-mediated interventions (and seven randomized control trials) designed to reduce youth externalizing and other problem behaviors to determine if, and for how long, these interventions may have crossover effects on youth DA symptoms. Moderation of intervention effects by youth biological sex, developmental period, number of prior placements, and race/ethnicity was also examined. Youth (N = 1891; 59% female; ages 4 to 18 years) behaviors were assessed via the Child Behavior Checklist, Parent Daily Report, and Eyberg Child Behavior Inventory at baseline, the end of the interventions (4-6 months post baseline), and two follow-up assessments (9-12 months and 18-24 months post baseline), yielding 4830 total youth-by-time assessments. The interventions were effective at reducing DA symptoms at the end of the interventions; however, effects were only sustained for one program at the follow-up assessments. No moderation effects were found. The current study indicates that parent-mediated interventions implemented during childhood or adolescence aimed at reducing externalizing and other problem behaviors had crossover effects on youth DA symptoms at the end of the interventions. Such intervention effects were sustained 12 and 24 months later only for the most at-risk youth involved in the most intensive intervention.

BACKGROUND AND OBJECTIVES: Early obesity treatment seems to be the most effective, but few treatments exist. In this study, we examine the effectiveness of a parent-only treatment program with and without booster sessions (Booster or No Booster) focusing on parenting practices and standard treatment (ST). METHODS: Families of children 4 to 6 years of age with obesity were recruited from 68 child care centers in Stockholm County and randomly assigned to a parent-only program (10 weeks) with or without boosters (9 months) or to ST. Treatment effects on primary outcomes (BMI z score) and secondary outcomes (BMI and waist circumference) during a 12-month period were examined with linear mixed models. The influence of sociodemographic factors was examined by 3-way interactions. The clinically significant change in BMI z score (-0.5) was assessed with risk ratios. RESULTS: A total of 174 children (mean age: 5.3 years [SD = 0.8]; BMI z score: 3.0 [SD = 0.6], 56% girls) and their parents (60% foreign background; 39% university degree) were included in the analysis (Booster, n = 44; No Booster, n = 43; ST, n = 87). After 12 months, children in the parent-only treatment had a greater reduction in their BMI z score (0.30; 95% confidence interval [CI]: -0.45 to -0.15) compared with ST (0.07; 95% CI: -0.19 to 0.05). Comparing all 3 groups, improvements in weight status were only seen for the Booster group (-0.54; 95% CI: -0.77 to -0.30). The Booster group was 4.8 times (95% CI: 2.4 to 9.6) more likely to reach a clinically significant reduction of ≥0.5 of the BMI z score compared with ST. CONCLUSION: A parent-only treatment with boosters outperformed standard care for obesity in preschoolers.

Youth who are aging out of the foster care system face significant barriers to accessing substance use treatment. Mobile interventions have shown efficacy for several mental and physical health issues and may be helpful in overcoming barriers facing foster youth with substance use problems. A program (iHeLP) for substance use reduction was developed that used a computerized screening and brief intervention (SBI) followed by six months of dynamically-tailored text messages. The program was shown to focus groups of youth (Nâ¯=â¯24) ages 18-19 who recently left foster care and had moderate to severe substance use risk. Focus group feedback was used to modify iHeLP prior to delivery in an open trial (Nâ¯=â¯16). Both study phases included assessments of feasibility and acceptability; the open trial also included assessments of substance use outcomes at 3 and 6 months. Focus groups indicated a high level of acceptability for the proposed intervention components. Of those screened for the open trial, 43% were eligible and 74% of those eligible enrolled, indicating good feasibility. Retention through the final follow-up was 59%, and drop out was associated with involvement in the criminal justice system. Participant ratings for liking, ease of working with, interest in and respectfulness of the SBI were high. Satisfaction ratings for the texting component were also high. A computerized brief screening intervention for substance use risk reduction together with tailored text messaging is both feasible and highly acceptable among youth who have recently aged-out of foster care.

Youth exiting foster care represent a unique, at-risk population in that they receive supportive health services while under the umbrella of the foster care system, but access to care can drop precipitously upon release from foster custody. Traditional means of substance use treatment may not meet the needs of this vulnerable population. Mobile interventions, however, have demonstrated high acceptability and efficacy across a range of mental and physical health issues. The specific advantages to mobile interventions dovetail well with the barriers faced by youth exiting foster care. This study describes the feasibility, acceptability, and initial efficacy of iHeLP, a computer- and mobile phone-based intervention based in Motivational Interviewing for reducing substance use among youth exiting foster care (n = 33). Participants were randomly assigned to either iHeLP or a contact control, each of which lasted six months. Feasibility was evaluated through eligibility and enrollment rates at baseline, and retention and intervention reach rates 3, 6, 9, and 12 months later. Acceptability was measured through a 5-item satisfaction measure and exit interviews. The two groups were then compared on a monthly measure of substance use. Study enrollment, retention, response rate, engagement, and satisfaction were all very good. Participants receiving iHeLP reported higher percent days abstinent than the control group, with effect sizes ranging from 0.32 to 0.62. Technology-based interventions such as iHeLP may be attractive to this population and support efforts towards reductions in substance use.
RESUMO
Youth in foster care have limited access to substance use services for a variety of reasons. Attempts to unpack this health disparity have focused on foster care systems, administrators, providers, and foster parents. This study seeks to understand the perspectives of youth themselves, with the hope of understanding their experiences with and preferences for such services. Analyses of focus groups with youth who had recently left foster care suggested concrete and perceptual facilitators/barriers to treatment. Concrete facilitators/barriers included the need for expanding social support, access to multiple service options, and tailored intervention approaches. Perceptual concerns revolved around understanding each individual's readiness to change, feeling judged by authority figures, and desiring help from people with lived experience. Participants also described novel intervention ideas, including a focus on technology-based approaches. By relying on youth voices, we can improve upon the current state of substance use interventions within foster care.

Although the effectiveness of interventions for prevention and treatment of mental health and behavioral problems in abused and neglected youth is demonstrated through the accumulation of evidence through rigorous and systematic research, it is uncertain whether use of research evidence (URE) by child-serving systems leaders increases the likelihood of evidence- based practice (EBP) implementation and sustainment. Information on URE was collected from 151 directors and senior administrators of child welfare, mental health and juvenile justice systems in 40 California and 11 Ohio counties participating in an RCT of the use of community development teams (CDTs) to scale up implementation of Treatment Foster Care Oregon over a 3 year period (2010-12). Separate multivariate models were used to assess independent effects of evidence acquisition (input), evaluation (process), application (output), and URE in general (SIEU Total) on two measures of EBP implementation, highest stage reached and proportion of activities completed at pre-implementation, implementation and sustainment phases. Stage of implementation and proportion of activities completed in the implementation and sustainment phases were independently associated with acquisition of evidence and URE in general. Participation in CDTs was significantly associated with URE in general and acquisition of research evidence in particular. Implementation of EBPs for treatment of abused and neglected youth does appear to be associated with use of research evidence, especially during the later phases.
RESUMO
PURPOSE: Intervention content written by adults for youth can result in miscommunication due to generational and cultural differences. Inviting at-risk youth to participate in the creation of intervention material can augment acceptability for their peers. METHODS: To improve intervention messaging, the present study examines the utility of a card sort technique when creating cellular phone text messages to be used in a preventive substance use intervention. During focus groups with 24 youth who are exiting the foster care system - a population with distinct cultural attributes - participants were asked to rate stage of change-specific health messages rooted in Motivational Interviewing and the Transtheoretical Model. RESULTS: Participants unanimously favored content that encouraged autonomy and choice. Statements that invited a "look to the future" were also rated favorably. Messages that referenced the past were not rated well, as were suggestions for professional assistance. Finally, encouragement to receive social support for change was met with ambivalence. While some participants regarded support as helpful, many others felt a severe lack of support in their lives, possibly prompting further substance use. CONCLUSIONS: Youth exiting foster care constitute a unique population whose voice is paramount in the development of interventions. The content present in traditional approaches to substance use prevention (e.g., increasing social support) may not apply to this group of vulnerable youth. The card sort technique has strong potential to evoke youth-specific intervention content that is more readily understood and accepted by target audiences.
RESUMO
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.

This report is one of a series of outcome evaluation studies for parent-training procedures tailored specifically to families of preadolescent antisocial children. Referred families were screened to identify 19 problem children who were observed in their homes to be high-rate social aggressors. Cases were randomly assigned to the parent-training procedures or to a waiting-list comparison group. All but one of the latter accepted a referral for treatment elsewhere in the community. After an average of 17hours of therapy time, the cases in the experimental group were terminated. Posttreatment observation data were collected in the homes of both the experimental and the comparison groups. The results indicated that, relative to the changes in the comparison sample, the parent-training sample showed a significantly greater reduction in the observed rates of deviant child behavior.
RESUMO
This paper reviews the evolution of the Oregon model of family behavior therapy over the past four decades. Inspired by basic research on family interaction and innovation in behavior change theory, a set of intervention strategies were developed that were effective for reducing multiple forms of problem behavior in children (e.g., Patterson, Chamberlain, & Reid, 1982). Over the ensuing decades, the behavior family therapy principles were applied and adapted to promote children's adjustment to address family formation and adaptation (Family Check-Up model), family disruption and maladaptation (Parent Management Training-Oregon model), and family attenuation and dissolution (Treatment Foster Care-Oregon model). We provide a brief overview of each intervention model and summarize randomized trials of intervention effectiveness. We review evidence on the viability of effective implementation, as well as barriers and solutions to adopting these evidence-based practices. We conclude by proposing an integrated family support system for the three models applied to the goal of reducing the prevalence of severe problem behavior, addiction, and mental problems for children and families, as well as reducing the need for costly and largely ineffective residential placements.

OBJECTIVES: This article describes the Standard Interview for Evidence Use (SIEU), a measure to assess the level of engagement in acquiring, evaluating, and applying research evidence in health and social service settings. METHOD: Three scales measuring input, process, and output of research evidence and eight subscales were identified using principal axis factor analysis and parallel analysis of data collected from 202 state and county child welfare, mental health, and juvenile justice systems leaders. RESULTS: The SIEU scales and subscales demonstrate strong internal consistency as well as convergent and discriminant validity. CONCLUSIONS: The SIEU is easy to use and can be administered as a complete scale or as three smaller scales to separately examine evidence in acquisition, evaluation, or application. The measure demonstrates potential in understanding the role of research evidence in service settings and in monitoring the process of evidence-based practice and application of scientific principles in social work practice.
RESUMO
With an ever increasing gap between need and availability for substance use services, more scalable and efficient interventions are needed. For youth in the foster care system, this gap is dramatic and expands as they leave care. Effective prevention services are strongly needed for this group of vulnerable young people. We propose a novel technology-driven intervention for preventing problematic substance use among youth receiving foster care services. This intervention approach would extend the work in brief computerized interventions by adding a text message-based booster, dynamically tailored to each individual's readiness to change. It also combats many barriers to service receipt. Dynamically tailored interventions delivered through technologies commonly used by adolescents and young adults have the strong potential to reduce the burden of problematic substance use.
RESUMO
Opportunities to evaluate strategies to create system-wide change in the child welfare system (CWS) and the resulting public health impact are rare. Leveraging a real-world, system-initiated effort to infuse the use of evidence-based principles throughout a CWS workforce, a pilot of the R3 model and supervisor-targeted implementation approach is described. The development of R3 and its associated fidelity monitoring was a collaboration between the CWS and model developers. Outcomes demonstrate implementation feasibility, strong fidelity scale measurement properties, improved supervisor fidelity over time, and the acceptability and perception of positive change by agency leadership. The value of system-initiated collaborations is discussed.

BACKGROUND: Most juvenile offenders desist from offending as they become adults, but many continue and ultimately enter the adult corrections system. There has been little prospective examination of which variables may predict the latter transition, particularly for women. AIMS: Our aim was to find out, for men and women separately, what variables identifiable in adolescent offenders predict their continuation of offending into adult life. METHODS: Participants were 61 male and 81 female youths who had been referred from the juvenile justice system for chronic delinquency and recruited into randomised controlled trials comparing Multidimensional Treatment Foster Care with group care ('treatment as usual'). All participants had attained adulthood by the time of our study. We first examined gender differences in childhood risk factors and then used Cox proportional-hazards models to estimate the relationship of potential risk factors to first adult arrest. RESULTS: Results indicated that, for men, juvenile justice referrals alone predicted risk of any first adult arrest as well as arrest for felony arrest specifically. Each additional juvenile referral increased the risk of any adult arrest by 9% and of adult felony arrest by 8%. For women, family violence, parental divorce and cumulative childhood risk factors, but not juvenile justice referrals, were significant predictors of adult arrest. Each additional childhood risk factor increased the risk of adult arrest by 21%. Women who experienced parental divorce were nearly three times more likely to be arrested as an adult, and those who experienced family violence 2.5 times more so than those without such experiences. CONCLUSIONS AND IMPLICATIONS FOR PRACTICE: We found preliminary evidence of gender differences in childhood risk factors for adult offending, and, thus potentially, for the development and use of interventions tailored differently for girls and boys and young men and young women to reduce their risk of becoming adult recidivists.

During the past decade, there have been increased efforts to implement evidence-based practices into child welfare systems to improve outcomes for children in foster care and their families. In this paper, the implementation and evaluation of a policy-driven large system-initiated reform is described. Over 250 caseworkers and supervisors were trained and supported to implement two evidence-based parent focused interventions in five private agencies serving over 2,000 children and families. At the request of child welfare system leaders, a third intervention was developed and implemented to train the social work workforce to use evidence-based principles in everyday interactions with caregivers (including foster, relative, adoptive, and biological parents). In this paper, we describe the policy context and the targeted outcomes of the reform. We discuss the theory of the interventions and the logistics of how they were linked to create consistency and synergy. Training and ongoing consultation strategies used are described as are some of the barriers and opportunities that arose during the implementation. The strategy for creating a path to sustainability is also discussed. The reform effort was evaluated using both qualitative and quantitative methods; the evaluation design, research questions and preliminary results are provided.

BACKGROUND: While obesity has been shown to be difficult to treat in school aged children and in adolescence, promising results have been detected for children who started treatment in early childhood. Yet knowledge on the effectiveness of structured early childhood obesity treatment programs is limited, preventing the widespread implementation of such programs. The main objective of this study is to evaluate the effectiveness of early treatment of childhood obesity with respect to treatment focus (parenting practices or lifestyle), length and intensity. The study will also examine the influence of gender, age, parental weight status, parenting practices, child behavior as well as parents' socioeconomic status and child and parental psychosocial health on children's weight status. METHODS/DESIGN: This is a parallel open label randomized controlled trial assessing two different behavioral treatment approaches offered in three conditions to families with children aged 4-6 years in Stockholm County, Sweden. Children (n = 180) identified as obese will be referred from primary child health care, school health care, and from outpatient pediatric clinics, and randomized to: 1) a standard treatment with focus on lifestyle, provided within the current healthcare system (n = 90); 2) a 10-session, 1.5 h/week group treatment with focus on parenting (n = 45); or 3) the same group treatment as 2) with additional follow-up sessions (n = 45). The primary study outcome is change in children's body mass index standard deviation score (BMI SDS) one year post-baseline. Secondary outcomes include changes in children's waist circumference, metabolic health, lifestyle patterns (Food Frequency Questionnaire), obesity-related child behaviors (Child Eating Behavior Questionnaire and Lifestyle Behavior Checklist, Problem Scale), parents' general and feeding parenting practices (Communicating with Children and Child Feeding Questionnaire) and lifestyle-specific self-efficacy (Lifestyle Behavior Checklist, Confidence Scale), family functioning (Family Assessment Device), child and parental psychosocial health (Child Behavior Checklist and Beck's Depression Inventory II). DISCUSSION: This study will facilitate a close examination of key components of treatment for obesity during early childhood and mechanisms of change. Results from this study will lead to better healthcare options for obesity treatment during early childhood and ultimately to the prevention of obesity later in life.

The proportion of the juvenile justice population that comprises females is increasing, yet few evidence-based models have been evaluated and implemented with girls in the juvenile justice system. Although much is known about the risk and protective factors for girls who participate in serious delinquency, significant gaps in the research base hamper the development and implementation of theoretically based intervention approaches. In this review, we first summarize the extant empirical work about the predictors and sequelae of juvenile justice involvement for girls. Identified risk and protective factors that correspond to girls' involvement in the juvenile justice system have been shown to largely parallel those of boys, although exposure rates and magnitudes of association sometimes differ by sex. Second, we summarize findings from empirically validated, evidence-based interventions for juvenile justice-involved youths that have been tested with girls. The interventions include Functional Family Therapy, Multisystemic Therapy, Multidimensional Family Therapy, and Treatment Foster Care Oregon (formerly known as Multidimensional Treatment Foster Care). We conclude that existing evidence-based practices appear to be effective for girls. However, few studies have been sufficiently designed to permit conclusions about whether sex-specific interventions would yield any better outcomes for girls than would interventions that already exist for both sexes and that have a strong base of evidence to support them. Third, we propose recommendations for feasible, cost-efficient next steps to advance the research and intervention agendas for this under-researched and underserved population of highly vulnerable youths.

Girls in the juvenile justice system are at increased risk for contracting HIV/AIDS. Sexual risk behavior was examined in 166 females with juvenile justice involvement who were followed from adolescence to young adulthood. Results indicated that childhood sexual abuse increased the incidence of unsafe sex during young adulthood, which was subsequently associated with contraction of a sexually transmitted infection (STI). Further, girls' comfort in talking with their partners about safer sex practices during adolescence moderated the association between childhood sexual abuse and unsafe sex, such that girls who had been sexually abused and were uncomfortable talking to their partners about safer sex during adolescence had an 8.5-fold increase in unsafe sex in young adulthood. The identification of behaviors amenable to intervention in the prevention of HIV/AIDS risk in this high-risk population is discussed.
RESUMO
Childhood sexual abuse (CSA) histories are prevalent among adolescent girls in the juvenile justice system (JJS) and may contribute to their high rates of suicidal behavior. Among 166 JJS girls who participated in an intervention trial, baseline CSA and covariates were examined as predictors of suicide attempt and nonsuicidal self-injury (NSSI) reported at long-term follow-up (7-12 years later). Early forced CSA was related to lifetime suicide attempt and NSSI history and (marginally) to postbaseline attempt; effects were not mediated by anxiety or depressive symptoms. Findings suggest that earlier victimization and younger entry into JJS are linked with suicide attempt and NSSI.

OBJECTIVE: Neurodevelopmental theories of psychosis highlight the potential benefits of early intervention, prevention, and/or preemption. How early intervention should take place has not been established, nor whether interventions based on social learning principles can have preemptive effects. The objective was to test whether a comprehensive psychosocial intervention can significantly alter psychotic symptom trajectories during adolescence-a period of heightened risk for a wide range of psychopathology. METHOD: This study was a randomized controlled trial (RCT) of Multidimensional Treatment Foster Care (MTFC) for delinquent adolescent girls. Assessment of psychotic symptoms took place at baseline and then 6, 12, 18, and 24 months post-baseline using a standardized self-report instrument (Brief Symptom Inventory). A second source of information about psychotic symptoms was obtained at baseline or 12 months, and again at 24 months using a structured diagnostic interview (the Diagnostic Interview Schedule for Children [DISC]). RESULTS: Significant benefits for MTFC over treatment as usual for psychosis symptoms were observed over a 24-month period. Findings were replicated across both measures. Effects were independent of substance use and initial symptom severity and persisted beyond the initial intervention period. CONCLUSION: Ameliorating nonclinical psychotic symptoms trajectories beginning in mid-adolescence via a multifaceted psychosocial intervention is possible. Developmental research on nonclinical psychotic symptoms and their prognostic value should be complemented by more psychosocial intervention research aimed at modifying these symptom trajectories early in their natural history.
