Abstract

Objective: 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. Method: 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. Results: 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). Conclusions: 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.
