The reliability and validity of the 12-item General Functioning (GF) subscale of the McMaster Family Assessment Device (FAD) is reported here. Psychometric properties of the FAD have been previously determined, but no independent assessment has been made of the GF subscale, which was used to measure family functioning in the Ontario Child Health Study (OCHS). Reliability was measured by Chronbach's alpha and split-half correlation. Validity was assessed by hypothesizing the relationships expected between the GF scores and other family variables included in the OCHS data set. The results indicate good reliability, and all hypotheses of validity were supported. The brevity and ease of administering the GF subscale recommend it for further use in survey research in which a global assessment of family functioning is required.
本文报告了麦克马斯特家庭评估设备（FAD）的12项总体功能（GF）分量表的信度和效度。FAD的心理测量特性此前已确定，但尚未对用于安大略儿童健康研究（OCHS）中测量家庭功能的GF分量表进行独立评估。通过克朗巴赫α系数和分半相关来测量信度。通过假设GF得分与OCHS数据集中包含的其他家庭变量之间预期的关系来评估效度。结果表明该量表具有良好的信度，所有效度假设均得到支持。GF分量表简短且易于施测，建议在需要对家庭功能进行整体评估的调查研究中进一步使用。
