身体鉴赏量表(BAS；Avalos，Tylka，&Wood-Barcalow，2005)被认为是一种积极的身体形象衡量标准，由13个条目组成，评估个人对自己身体的接受、好评和尊重。虽然BAS已经积累了心理测量学支持，但我们通过修改某些BAS项目的措辞(以消除特定性别的版本和基于身体不满的语言)并根据积极的身体形象研究开发额外的项目来改进它。在三项研究中，我们检查了修改后的、新开发的和保留的条目，以确定它们在大学和在线社区(Amazon Machine Turk)样本中的心理测量学特性，样本包括820名女性和767名男性。经过探索性因素分析，保留了10个条目(原BAS条目5个)。验证性因素分析支持BAS-2‘S的单维度和跨性别、跨样本类型的不变性。其内部一致性、重测信度和结构效度(收敛效度、递增效度和判别效度)得到支持。BAS-2是一种心理测量学良好的积极身体形象测量工具，适用于研究和临床设置。(C)2014爱思唯尔有限公司。保留所有权利。
Considered a positive body image measure, the 13-item Body Appreciation Scale (BAS; Avalos, Tylka, & Wood-Barcalow, 2005) assesses individuals' acceptance of, favorable opinions toward, and respect for their bodies. While the BAS has accrued psychometric support, we improved it by rewording certain BAS items (to eliminate sex-specific versions and body dissatisfaction-based language) and developing additional items based on positive body image research. In three studies, we examined the reworded, newly developed, and retained items to determine their psychometric properties among college and online community (Amazon Mechanical Turk) samples of 820 women and 767 men. After exploratory factor analysis, we retained 10 items (five original BAS items). Confirmatory factor analysis upheld the BAS-2's unidimensionality and invariance across sex and sample type. Its internal consistency, test-retest reliability, and construct (convergent, incremental, and discriminant) validity were supported. The BAS-2 is a psychometrically sound positive body image measure applicable for research and clinical settings. (C) 2014 Elsevier Ltd. All rights reserved.
