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.
斯莫拉克和默嫩（2008）编制并评估了“瘦身驱力量表”（DLS），该量表用于衡量男性和女性对体脂和紧致、健康肌肉的渴望程度。该量表的心理测量学特性通过对爱尔兰男性的在线样本（N=545）进行了研究。验证性因素分析表明，单维因子结构能够充分匹配观察数据（即，拟合指数表明模型拟合可接受）。分析还表明，DLS 产生了可靠且聚合有效的分数，表明该量表有望成为衡量瘦身驱力的指标。讨论了该研究的优点和局限性，包括互联网研究固有的问题。还提供了未来研究的方向，例如需要进行更多的心理测量学工作。
