✦ Synopsis

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.
