DESCRIPTION (Adapted from applicant's abstract): The purpose of this competing continuation proposal is to extend a program of research that began in September 1992, and has included (a) consumer-oriented studies of actors influencing participation in family competency-training interventions, and (b) four waves of data collection in a prevention trail evaluating the efficacy of the Iowa Strengthening Families Program (ISFP) among rural families with sixth graders. Promising results from growth curve analyses and mixed model ANCOVAs of 1- and 2-year follow-up data underscore the importance of continuing the study as the youth in our sample enter the highest risk years for the presentation of problem behaviors. The first aim of this proposal is to collect further prevention trial follow-up data, in order to examine long-term outcomes of the ISFP. A second aim is to model processes influencing ISFP outcomes, including mechanisms underlying intervention-related change in parent and child outcomes that are proximally and distally targeted by the ISFP. These specific aims will be achieved through third and fourth year follow-up data collection, along with analyses of these and prior waves of data from the ongoing prevention trial. This trial began with the random assignment of 33 rural schools having a sixth grade and meeting the criteria for the federal school lunch program. Multi-informant, multi-method measurement procedures at pretesting involved 667 families from these schools; posttesting, 1- and 2-year follow-up assessments have been completed; retention rates have been slightly better than predicted. Data analyses to date have shown (a) support for models of factors influencing ISFP participation; (b) significant, positive effects of the ISFP on effective parenting, child competencies, and child problem behaviors; (c) differences in problem behavior trajectories in intervention and control groups; and (d) support for models of intervention-related mechanisms of change in family processes. Comparisons between intervention and control groups will be conducted at the planned follow-up data collection points. Growth curve modeling will be employed to examine whether the increasing divergence of intervention and control group outcomes observed on key child outcomes to date is sustained, and whether outcomes differ among risk-related subgroups. Planned modeling of intervention change-related mechanisms will include multi-sample structural equation models of interrelationships among targeted parenting and child outcomes.

描述(改编自申请人的摘要)：本报告的目的 竞争性延续建议是延长一项研究计划，该计划 开始于1992年9月，包括：(A)以消费者为导向的研究 影响参加家庭能力培训的行为者 干预措施，以及(B)预防试验中的四波数据收集 评估爱荷华州强化家庭计划(ISFP)的效果 在有六年级学生的农村家庭中。从增长中获得有希望的结果 1年和2年随访资料的曲线分析和混合模型方差分析 强调作为我们样本中的青年继续学习的重要性 输入出现问题行为的风险最高的年份。 该提案的第一个目的是收集进一步的预防试验。 跟踪数据，以检查ISFP的长期结果。一个 第二个目标是对影响ISFP结果的过程进行建模，包括 父母和子女干预相关变化的潜在机制 ISFP近端和远端目标的结果。这些 具体目标将通过第三年和第四年的跟踪数据实现 收集，以及对这些数据和之前的数据浪潮的分析 正在进行的预防试验。这项试验从随机分配的33人开始 农村学校有六年级，并符合联邦政府的标准 学校午餐计划。多信息者、多方法测量程序 前测涉及这些学校的667个家庭；后测，1-和 已经完成了两年的跟踪评估；保留率 略好于预期。 到目前为止的数据分析表明：(A)支持因素模型 影响ISFP参与；(B)重大的积极影响 关于有效育儿、儿童能力和儿童问题的ISFP 行为；(C)干预中问题行为轨迹的差异 以及(D)支持与干预相关的模式 家庭过程中的变化机制。干预措施之间的比较 对照组将在计划的随访数据中进行 收集点。将使用增长曲线建模来检验 干预组和对照组结果的差异是否越来越大 到目前为止对关键儿童结果的观察是否持续，以及结果是否 在与风险相关的亚组中有所不同。干预的计划模型 与变化相关的机制将包括多样本结构方程 有针对性的育儿方式和儿童结果之间相互关系的模型。
