DESCRIPTION (provided by applicant): Problem And Significance: Reliable and valid measures of family functioning may help to reduce health disparities by correctly identifying both strengths and weaknesses in families and by directing scarce resources where needed. Many measures of family functioning have shown unacceptable reliability and validity when used with the growing population of low-income African American single-parent families. A reliable and valid measure of family functioning in this population will allow family scientists to better identify both strengths and weaknesses in this population of families and to develop interventions to enhance family strengths. Purpose: The purpose of this study is produce a reliable and valid instrument to assess family functioning in this underserved population by conducting psychometric testing and further refinement of the 42-item Family Effectiveness Measure (FEM), an instrument developed from qualitative data to assess family functioning with low-income, African American, single-parent families with children. Aims: The specific aims are to assess the following psychometric properties of the FEM: 1) factor structure, by conducting exploratory factor analysis; 2) reliability, by determining internal consistency and stability (testretest) coefficients; 3) construct validity, by testing hypothesized relationships between the FEM and measures of aspects of family well-being (family conflict, satisfaction with family interaction) and individual well-being (depression), which are theoretically and empirically known to be related to family functioning; and 4) construct validity, by conducting Rasch analysis to further evaluate the dimensionality of the measure, the extent to which items tap the breadth of the construct, and the extent to which persons respond to items in coherent ways. Methods: The FEM and validating instruments will be administered one time to a sample of 420 low-income African American single mothers. A subsample of 84 (20%) will be randomly selected to complete the FEM after 2 weeks to assess stability (test-retest) reliability. Factor analysis will be performed, reliability coefficients will be calculated, and hypothesized relationships among the measures will be tested by correlations. Items will be revised, added, or eliminated if warranted based on the study findings.

描述（由申请人提供）： 问题和意义：通过正确识别家庭的优势和劣势以及将稀缺资源用于需要的地方，可靠且有效的家庭功能测量可能有助于减少健康差异。当用于不断增长的低收入非裔美国单亲家庭人口时，许多家庭功能衡量标准都显示出令人无法接受的可靠性和有效性。对这一群体的家庭功能进行可靠有效的衡量将使家庭科学家能够更好地识别这一家庭群体的优势和劣势，并制定干预措施以增强家庭优势。 目的：本研究的目的是通过进行心理测量测试并进一步完善 42 项家庭效能测量 (FEM)（一种根据定性数据开发的用于评估家庭的工具），制定可靠且有效的工具来评估这一服务不足人群的家庭功能。与低收入、非裔美国人、有孩子的单亲家庭一起运作。 目的：具体目的是评估 FEM 的以下心理测量特性：1）通过进行探索性因素分析来确定因素结构； 2）可靠性，通过确定内部一致性和稳定性（testretest）系数； 3）通过测试FEM与家庭幸福感（家庭冲突、家庭互动满意度）和个人幸福感（抑郁）方面的衡量指标之间的假设关系来构建有效性，这些关系在理论上和经验上都已知与家庭相关发挥作用； 4）构建有效性，通过进行Rasch分析来进一步评估测量的维度、项目利用构建广度的程度以及人们以连贯方式对项目做出反应的程度。 方法：将对 420 名低收入非洲裔美国单身母亲进行一次 FEM 和验证工具测试。两周后将随机选择 84 个子样本 (20%) 来完成 FEM，以评估稳定性（重测）可靠性。将进行因子分析，计算可靠性系数，并通过相关性来测试措施之间的假设关系。如果根据研究结果有必要，项目将被修改、添加或删除。
