Psychological concerns are frequently indexed by psychometric questionnaires but the mental representations that they seek to quantify are difficult to visualise. We used a set of questionnaires designed to measure men’s concept of their bodies including: the Drive for Muscularity Scale (DMS; McCreary & Sasse, 2000), the Perceived Sociocultural Pressures Scale (PSPS; Stice, Nemeroff, & Shaw, 1996a), the Body Appreciation Scale (BAS-2; Tylka & Wood-Barcalow, 2015), and the Sociocultural Attitudes Towards Appearance Questionnaire-3 (SATAQ-3; Thompson, van den Berg, Roehrig, Guarda, & Heinberg, 2004). We combined their use with an interactive 3D modelling programme to allow men to create computer-generated representations of their ideal bodies. We used a principal component analysis to extract those shape components of our participants’ CGI ideal bodies that were predicted by the questionnaires and reconstructed the body shapes that these questionnaires were capturing. Moving from the lowest to the highest score on both the DMS and SATAQ corresponded with changes in muscularity, particularly muscle mass and definition. This approach allows us to demonstrate the actual body features that are being captured by a particular questionnaire.

心理问题经常被心理测量问卷索引，但他们试图量化的心理表征很难形象化。我们使用了一套旨在测量男性身体概念的问卷，包括：肌肉发达量表（DMS；McCreary & Sasse，2000）、感知社会文化压力量表（PSPS；Stice、Nemeroff 和 Shaw，1996a）、身体欣赏量表（BAS-2；Tylka & Wood-Barcalow，2015 年）和外貌社会文化态度问卷 3（SATAQ-3；Thompson、van den Berg、Roehrig、Guarda 和 Heinberg，2004 年）。我们将它们的使用与交互式 3D 建模程序相结合，使男性能够创建他们理想身体的计算机生成表示。我们使用主成分分析来提取问卷预测的参与者 CGI 理想身体的形状成分，并重建这些问卷所捕获的身体形状。从 DMS 和 SATAQ 的最低分到最高分对应于肌肉强度的变化，尤其是肌肉质量和清晰度。这种方法使我们能够展示特定问卷所捕获的实际身体特征。
