title: Psychometric properties of Yelland and Tiggemann's Drive for Muscularity Scale.
abstract: The purpose of the current study was to examine the dimensionality and validity of Yelland and Tiggemann's Drive for Muscularity Scale (YT-DMS). Participants were college students (305 women, M(AGE)=20.15 years, SD=4.00; 356 men, M(AGE)=20.24 years, SD=3.85) who completed the YT-DMS, the Drive for Muscularity Attitudes Questionnaire, the Drive for Leanness Scale, the Drive for Thinness Scale, and a socio-demographic questionnaire. Results indicated the YT-DMS had a stable unidimensional factor structure in both genders, and the pattern of relationships generally supported the measure's criterion and construct validity. These results reveal the YT-DMS has promise, but helps identify possible areas for improvement, such as a greater focus on sampling the content domain associated with the drive for muscularity.
