Validation of body esteem measures in pre- and early adolescent male and female populations is essential as gender differences regarding weight and body size concerns often emerge during this developmental period.
The purpose of the current study was to analyze psychometric properties of the Body Esteem Scale for Adolescents and Adults (BESAA) in order to determine the utility of this instrument in a population of early adolescent males and females.
A cross-sectional survey was completed by 86% of sixth-graders (N = 299) at a single US middle school.
Confirmatory factor analysis provides support for two interpretable and interrelated subscales of the BESAA [Body esteem (BE)-weight and BE-appearance], both of which exhibit good internal consistency reliability and evidence of concurrent validity based on correlations with self-esteem and BMI. However, the following concerns about the BESAA were identified: (a) certain scale items may lack structural invariance across gender and developmental age group; (b) multiple items demonstrated a tendency to load on both factors; (c) several item pairs are similar in wording and/or meaning and show a tendency for correlated errors; and (d) an additional BE dimension assessing views about one's muscle build and strength may be needed to fully capture body esteem among adolescent males.
Findings suggest cognitive interviewing and additional psychometric studies are needed for modifying the BESAA for use among early adolescents.
在青春期前和青春期早期的男性和女性群体中验证身体自尊测量非常重要，因为在这个发育阶段，与体重和身体大小有关的性别差异经常出现。
本研究的目的是分析青少年和成人身体自尊量表（BESAA）的心理测量特性，以确定该工具在青春期早期男性和女性群体中的适用性。
在美国一所中学，通过横断面调查完成了六年级学生的调查（N=299），完成率为 86%。
验证性因子分析支持 BESAA 的两个可解释和相互关联的分量表[身体自尊（BE）-体重和 BE-外貌]，这两个分量表都表现出良好的内部一致性可靠性和基于与自尊和 BMI 的相关性的同时效度证据。然而，该量表存在以下问题：（a）某些量表项目可能缺乏跨性别和发展年龄组的结构不变性；（b）多个项目表现出倾向于同时加载在两个因素上；（c）几个项目对在措辞和/或含义上相似，并且表现出相关错误的倾向；（d）可能需要评估对自己肌肉发达和力量的看法的额外 BE 维度，以充分捕捉青春期男性的身体自尊。
研究结果表明，需要进行认知访谈和额外的心理测量研究，以修改 BESAA 供青春期前青少年使用。
