Can evidence-based prevention programs be sustained in community practice settings? The Early Risers' Advanced-Stage Effectiveness Trial.

This study evaluated institutional sustainability of the Early Risers "Skills for Success" conduct problems prevention program. In a previous early-stage effectiveness trial Early Risers had been successfully implemented by a nonprofit community agency with guidance, supervision, technical assistance and fiscal support/oversight provided by program developers. The current advanced-stage effectiveness trial applied a randomized, control group design to determine whether this community agency could replicate earlier positive findings with a new cohort of participants, but with less direct involvement of program developers. An intent-to-intervene strategy was used to compare children randomly assigned to Early Risers or a no-intervention comparison group. Compared to results obtained in an early-stage effectiveness trial, program attendance rates were much lower and only one positive outcome was replicated. Failure to replicate program effects was not attributed to poor program implementation, because data collected pertaining to exposure, adherence and quality of delivery were acceptable, and a participation analysis showed that families who attended at higher levels did benefit. It was difficulties that the community agency experienced in engaging families in program components at recommended levels that primarily accounted for the results. Possible organizational barriers that impeded sustainability included unreliable transportation, poor collaboration between the agency and the local public school system, high staff turnover, agency downsizing, and fiduciary responsibility and accountability. It was concluded that both program developers and program providers need to be proactive in planning for sustainability.

Moving evidence-based drug abuse prevention programs from basic science to practice: "bridging the efficacy-effectiveness interface".

This article examines the challenges faced by developers of youth drug abuse prevention programs in transporting scientifically proven or evidence-based programs into natural community practice systems. Models for research on the transfer of prevention technology are described with specific emphasis given to the relationship between efficacy and effectiveness studies. Barriers that impede the successful integration of efficacy methods within effectiveness studies (e.g., client factors, practitioner factors, intervention structure characteristics, and environmental and organizational factors) are discussed. We present a modified model for program development and evaluation that includes a new type of research design, the hybrid efficacy-effectiveness study that addresses program transportability. The utility of the hybrid study is illustrated in the evaluation of the Early Risers "Skills for Success" prevention program.

Parent-adolescent conflict and its resolution in monogamous and polygamous Bedouin Arab families in southern Israel.

The purpose of this study was twofold: (1) to compare whether children from polygamous family structures significantly differ from children from monogamous family structures with regard to the frequency of parent-child conflict, and (2) whether children from these two structures employ different patterns of family conflict resolution. To address these questions, a random sample of 212 high school students (60.8% monogamous) completed a self-administered survey. The results of MANOVA show no significant differences (p > 0.05) between these two structures with regard to the frequency of parent-child conflict. The results also show similar conflict management styles between these two family structures within each of the following five domains (privacy, school and career, money spending, going out and leisure, and physical appearance). This study is unique in that it is the first empirical research to be conducted in the field of conflict resolution among youth and adolescents in polygamous marital structures and therefore, further investigation is needed to replicate these results utilizing different cross-cultural populations practicing polygamy.

Effects of pairing aggressive and nonaggressive children in strategic peer affiliation.

Examined the behavior of 118 second graders who participated in a 6-week summer school program that incorporated strategic peer affiliation (a "buddy system"). Moderately aggressive children (the targets of the intervention) were paired with nonaggressive peers throughout the program. All participants were observed playing foosball with their buddies and with aggressive and nonaggressive nonbuddies as teammates. Aggressive children had lower levels of disruptive behavior when their teammate was nonaggressive, regardless of whether the teammate was a buddy. Nonaggressive children showed elevated disruptive behavior when playing with an aggressive nonbuddy, but not when playing with an aggressive buddy. The highest level of aggressive behavior was seen in pairs of aggressive teammates who were friends. One year later, no increase in peer-rated aggressive behavior was found in either group. Results suggest that unidirectional peer influence is possible and that strategic peer affiliation can be an effective intervention that does not put nonaggressive children at risk for acquiring undesired behaviors.

Parceling component effects of a multifaceted prevention program for disruptive elementary school children.

This study examined predictors and outcomes of attendance in two standard components of a multifaceted preventive intervention aimed at children with early-onset disruptive behavior after 3 years of intervention. Mean rate of attendance in the Family Program, but not the Summer School Program, differed by level of child disruptiveness (grouping variable). Although predictors of attendance (SES, single-parent status, child IQ) did not differ across high- and low-disruptive groups, predictors of outcome were moderated by level of child disruptiveness for academic achievement and aggression outcomes, but not for social competence. Higher attendance in the Summer Program was associated with higher child social competence at Year 3 for all children. For academic achievement, higher attendance in the Summer Program was associated with higher scores for mild/moderately disruptive children and lower scores for highly disruptive children in Year 3. Higher attendance in the Family Program was associated with lower aggression scores for mild/moderately disruptive children. Findings highlight the importance of matching intervention components to the assessed or expressed needs of client subgroups.

Dissemination of an evidence-based prevention innovation for aggressive children living in culturally diverse, urban neighborhoods: the Early Risers effectiveness study.

This study evaluated the effectiveness of the Early Risers "Skills for Success" Program when implemented by neighborhood family resource centers available to urban children and their families. Kindergarten and first-grade children (n = 327) enrolled in 10 schools were screened for aggressive behavior, and randomized to two model variations of the Early Risers Program or a no-intervention control condition. The full-strength model (CORE + FLEX) included child and parent/family components whereas the partial model (CORE-only) offered only the child component. The intervention was delivered over two continuous years. CORE + FLEX children showed higher levels of program attendance than their CORE-only counterparts but no differences on outcomes measures were observed between models. When both program models were collapsed and compared to controls, program children showed significant gains on measures of school adjustment and social competence, the most aggressive program children showed reductions in disruptive behavior, and program parents reported reduced levels of stress.

Paroxetine treatment of pathological gambling: a multi-centre randomized controlled trial.

Previous studies have suggested the efficacy of serotonergic agents in the treatment of pathological gambling. The aim of the present study was to determine whether treatment with paroxetine in a large sample of subjects with pathological gambling would effectively diminish the severity of gambling symptoms. A 16-week, double-blind, placebo-controlled trial was conducted at five outpatient academic research centres in two countries (USA and Spain). Seventy-six outpatients (mean age 45.4+/-10.6 years; 30 women, 46 men) with pathological gambling were randomized to acute treatment with paroxetine in flexible daily dosages of 10-60 mg/day (n=36) or placebo (n=40). The primary outcome measure was the Clinical Global Impressions scale. Both the paroxetine- and the placebo-treated groups demonstrated comparable improvement at 16 weeks (59% response rate in the paroxetine group, 49% rate in the placebo group; chi squared=0.737; d.f.=1; P=0.390). Paroxetine consistently resulted in a greater percentage of responders at each study visit compared to placebo but failed to demonstrate statistical superiority to placebo on scores on the Clinical Global Impressions scale, the Yale-Brown Obsessive-Compulsive Scale Modified for Pathological Gambling, or the Gambling Symptom Assessment Scale. High rates of symptom improvement were observed in pathological gamblers receiving either paroxetine or placebo after 16 weeks. Paroxetine consistently demonstrated an advantage over placebo on the Clinical Global Impressions scale; however, a larger sample size may have registered significant differences.

The early risers longitudinal prevention trial: examination of 3-year outcomes in aggressive children with intent-to-treat and as-intended analyses.

The effects of participation following a 3-year preventive intervention trial targeting elementary school children with early-onset aggressive behavior were evaluated. Intent-to-treat analyses revealed that program participants, compared with controls, showed greater gains in social skills, academic achievement, and parent discipline, with mean scores in the normative range on the latter two constructs. As-intended participation in the Family Program, which included separate parent and child education and skills-training groups, was associated with improved parent discipline practices and gains in children's social skills, with level of child aggression moderating gains in academic achievement. Recommended level of FLEX family support contact time was associated with gains in academic achievement, concentration problems, and social skills, with parents of severely aggressive children showing greater reductions in parent distress.
