Int J Eat Disord. 1999 Mar;25(2):195-214. doi: 10.1002/(sici)1098-108x(199903)25:2<195::aid-eat9>3.0.co;2-b.
To describe the development, test-retest reliability, internal consistency, and convergent validity of the McKnight Risk Factor Survey-III (MRFS-III). The MRFS-III was designed to assess a number of potential risk and protective factors for the development of disordered eating in preadolescent and adolescent girls.
Several versions of the MRFS were pilot tested before the MRFS-III was administered to a sample of 651 4th through 12th- grade girls to establish its psychometric properties.
Most of the test-retest reliability coefficients of individual items on the MRFS-III were r > .40. Alpha coefficients for each risk and protective factor domain on the MRFS-III were also computed. The majority of these coefficients were r > .60. High convergent validity coefficients were obtained for specific items on the MRFS-III and measures of self-esteem (Rosenberg Self-Esteem Scale) and weight concerns (Weight Concerns Scale).
The test-retest reliability, internal consistency, and convergent validity of the MRFS-III suggest that it is a useful new instrument to assess potential risk and protective factors for the development of disordered eating in preadolescent and adolescent girls.
描述麦克奈特风险因素调查问卷第三版（MRFS-III）的编制过程、重测信度、内部一致性和收敛效度。MRFS-III旨在评估青春期前及青春期女孩饮食失调发展过程中的一些潜在风险和保护因素。
在对651名四至十二年级女孩进行MRFS-III测试以确定其心理测量学特性之前，先对MRFS的几个版本进行了预测试。
MRFS-III上各个项目的重测信度系数大多为r>.40。还计算了MRFS-III上每个风险和保护因素领域的阿尔法系数。这些系数大多为r>.60。MRFS-III上的特定项目与自尊量表（罗森伯格自尊量表）和体重关注量表（体重关注量表）的测量结果获得了较高的收敛效度系数。
MRFS-III的重测信度、内部一致性和收敛效度表明，它是评估青春期前及青春期女孩饮食失调发展过程中潜在风险和保护因素的一种有用的新工具。
