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（改编自申请人摘要）：本申请的目的 一个竞争性的继续计划是延长一个研究项目， 从1992年9月开始，包括（a）以消费者为导向的研究， 影响参与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 评估爱荷华州加强家庭计划的有效性 有六年级学生的农村家庭。 增长带来的可喜成果 1年和2年随访数据的曲线分析和混合模型ANCOVA 强调继续研究的重要性，因为我们样本中的年轻人 进入出现问题行为的最高风险年份。 这项建议的首要目的是收集进一步的预防试验 后续数据，以检查ISFP的长期结果。 一 第二个目标是模拟影响ISFP结果的过程，包括 父母和孩子的干预相关变化的潜在机制 ISFP的近端和远端目标结局。 这些 将通过第三和第四年的后续数据实现具体目标 收集，沿着对这些和先前来自 正在进行的预防试验。 试验开始时随机分配了33名 设有六年级并符合联邦标准的农村学校 学校午餐计划 多信息提供者、多方法测量程序 在预测试涉及667个家庭从这些学校;后测试，1-和 2-年后续评估已完成;保留率已 比预计的要好一点 迄今为止的数据分析表明：（a）支持因素模型 影响ISFP的参与;（B） 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 （d）支持与干预有关的模式 家庭进程中的变化机制。 干预措施之间的比较 对照组将在计划的随访数据时进行 收集点。 生长曲线模型将被用来检查 是否干预组和对照组结果的差异越来越大 迄今为止观察到的关键儿童成果是持续的， 在风险相关的亚组之间存在差异。 干预计划建模 变化相关机制将包括多样本结构方程 有针对性的养育和儿童成果之间的相互关系模型。
