After the original 15-item Drive for Muscularity Scale developed by McCreary et al. in 2004, a more theoretically based scale that replicates the original DMS subscales with a better conceptual clarity and a shorter number of items, i.e., the DMS-9, has recently been developed by Chaba et al. in 2018. We sought to contribute to the literature especially under the Arab context, by investigating the psychometric properties of an Arabic translation of the DMS-9 in a sample of Arabic-speaking Lebanese university students of both genders.
University students (N = 402; 55.2% females) from multiple universities in Lebanon were invited to fill the survey in this cross-sectional designed study (December 2022 and January 2023). Our sample was chosen using the snowball technique; a soft copy of the questionnaire was created using google forms software, and an online approach was conceived to proceed with the data collection.
Using an Exploratory Factor Analysis-to- Confirmatory Factor Analysis strategy, we found that the original two-factor model of the DMS proposed in the parent study was adequately replicated in our sample. The two DMS-9 factor scores showed very good McDonald's omega values (ω > 0.8). Findings also showed that gender invariance was achieved at the configural, metric, and scalar levels. Additionally, drive for muscularity scores correlated in the expected way with other study variables, providing support for the convergent and divergent validity of the Arabic DMS-9. Specifically, we found that greater drive for muscularity attitudes and behaviors significantly correlated with more severe muscle dysmorphic symptoms, inappropriate eating attitudes, muscle bias internalization, and lower body appreciation.
Findings preliminarily suggest that the Arabic DMS-9 is psychometrically sound and suitable tool to assess the drive for muscularity construct among Arabic-speaking community adults. Making the Arabic DMS-9 available will hopefully benefit the scientific community working in Arab settings, promote local and international research in this area, and offer descriptive data on how drive for muscularity may interfere with health indicators in the general Arab population.
2004 年，McCreary 等人最初开发了 15 项肌肉发达驱力量表（DMS）后，Chaba 等人于 2018 年最近开发了一种更具理论基础的量表，该量表复制了原始 DMS 分量表，具有更好的概念清晰度和更短的项目数量，即 DMS-9。我们试图通过在黎巴嫩男女大学生的阿拉伯语翻译样本中研究 DMS-9 的心理测量特性，为文献做出贡献，特别是在阿拉伯语背景下。
邀请来自黎巴嫩多所大学的大学生（N=402；55.2%为女性）参与这项横断面设计研究（2022 年 12 月至 2023 年 1 月）。我们的样本是使用滚雪球技术选择的；问卷的软拷贝是使用谷歌表单软件创建的，并且构思了一种在线方法来进行数据收集。
使用探索性因素分析-验证性因素分析策略，我们发现，母研究中提出的 DMS 的原始两因素模型在我们的样本中得到了充分复制。两个 DMS-9 因子得分显示出非常好的 McDonald's ω 值（ω>0.8）。研究结果还表明，在组态、度量和标度水平上实现了性别不变性。此外，肌肉发达驱力得分与其他研究变量以预期的方式相关，为阿拉伯语 DMS-9 的收敛和发散效度提供了支持。具体而言，我们发现，更强的肌肉发达态度和行为与更严重的肌肉畸形症状、不恰当的饮食态度、肌肉偏见内化以及身体欣赏程度降低显著相关。
研究结果初步表明，阿拉伯语 DMS-9 具有心理测量学上的合理性，是评估阿拉伯语社区成年人肌肉发达驱力结构的合适工具。提供阿拉伯语 DMS-9 将有望使在阿拉伯语环境中工作的科学界受益，促进该领域的本地和国际研究，并提供有关肌肉发达驱力如何影响普通阿拉伯人口健康指标的描述性数据。
