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：可靠和有效的家庭功能措施可能有助于通过正确识别家庭的优势和劣势以及在需要时指导稀缺资源来帮助减少健康差异。当与低收入非裔美国人单亲家庭的人口不断增长时，许多家庭功能的衡量标准都表现出不可接受的可靠性和有效性。对该人群中家庭功能的可靠和有效衡量将使家庭科学家更好地识别家庭人群中的优势和劣势，并制定干预措施以增强家庭优势。 目的：这项研究的目的是生产一种可靠且有效的工具，通过进行心理测试和进一步的改进42个项目的家庭有效性度量（FEM），这是一种从定性数据开发的工具，以评估与低收入的低收入，非裔美国人，非裔美国人，与儿童一起评估家庭功能，来评估该人群中的家庭功能。 目的：具体目的是通过进行探索性因素分析来评估FEM的以下心理测量特性：1）因子结构； 2）可靠性，通过确定内部一致性和稳定性（testRetest）系数； 3）构建有效性，通过测试FEM与家庭福祉方面（家庭冲突，对家庭互动的满意度）和个人福祉（抑郁）之间的假设关系，这些关系在理论上和经验上与家庭功能有关； 4）构造有效性，通过进行Rasch分析来进一步评估度量的维度，项目在多大程度上利用结构的广度以及人们以连贯的方式对项目响应的程度。 方法：将FEM和验证工具一次用于420个低收入非裔美国单身母亲的样本。 2周后，将随机选择84个（20％）的子样本以完成FEM，以评估稳定性（重测）可靠性。将进行因子分析，将计算可靠性系数，并通过相关性测试措施之间的假设关系。如果根据研究结果进行保证，将修改，添加或消除项目。
