Psychometric evaluation of the Drive for Leanness Scale in a sample of Irish men

Smolak and Murnen (2008) developed and assessed the Drive for Leanness Scale (DLS), a measure of men and women's desire to have limited body fat and toned, healthy muscles. The psychometric properties of this scale were investigated using an online sample of Irish men (N=545). Confirmatory fact...

Description
Summary:Smolak and Murnen (2008) developed and assessed the Drive for Leanness Scale (DLS), a measure of men and women's desire to have limited body fat and toned, healthy muscles. The psychometric properties of this scale were investigated using an online sample of Irish men (N=545). Confirmatory factor analyses suggested that a unidimensional factor structure adequately matched the observed data (i.e., fit indices suggested acceptable model fit). Analyses also showed that the DLS yielded reliable and convergent valid scores, suggesting that the scale holds promise as an indicant of the drive for leanness. Strengths and limitations associated with this study are discussed, including problems inherent in Internet research. Directions for future inquiry, such as the need for additional psychometric work, also are provided. ► We psychometrically evaluated the Drive for Leanness Scale (Smolak & Murnen, 2008). ► Confirmatory factor analyses indicated the scale's unidimensionality. ► Findings suggested that the scale yielded reliable scores. ► Tests of convergent validity were supported. ► More psychometric work is recommended.
