This study tested the psychometric characteristics of the Body Morph Assessment version 2.0 (BMA 2.0). A sample of 563 adults composed of four groups classified by gender and ethnicity (Caucasian men and women and African-American men and women) were studied. Support for the internal consistency and test-retest reliability of the BMA 2.0 was found for both men and women. A study of convergent validity was conducted. The BMA 2.0 was found to have adequate reliability and validity. Norms were established for the BMA 2.0 estimates of current body size (CBS), ideal body size (IBS), and acceptable body size (ABS) for Caucasian and African-American men and women. In summary, the BMA 2.0 is a reliable and valid computerized measure of CBS, IBS, ABS, the CBS-IBS discrepancy (body dissatisfaction), and provides an estimate of over/underestimation of body size as compared to individuals of the same sex and body mass index.
本研究测试了身体形态评估2.0版（BMA 2.0）的心理测量学特征。研究样本包括563名成年人，他们按性别和种族分为四组（白人男性和女性以及非裔美国男性和女性）。研究发现，BMA 2.0在男性和女性中均具有内部一致性和重测信度。进行了收敛效度研究。结果发现，BMA 2.0具有足够的信度和效度。为白人和非裔美国男性及女性的BMA 2.0当前身体尺寸（CBS）、理想身体尺寸（IBS）和可接受身体尺寸（ABS）估计值建立了常模。总之，BMA 2.0是一种可靠且有效的计算机化测量工具，可用于测量CBS、IBS、ABS、CBS - IBS差异（身体不满意程度），并能估计与同性及相同体重指数个体相比身体尺寸的高估/低估情况。
