The aim of this study was to evaluate the psychometric properties of SAVE-6 in the medical student population and assess its gender invariance. The sample consisted of 320 medical students aged 18-23 years (153 men and 167 women) who completed an anonymous online questionnaire. Data collection took place in June 2024. To assess the scale structure, a descriptive analysis of the items was carried out, followed by a confirmatory factor analysis (CFA). To analyze whether there were differences in the invariance of the measure by gender, a multigroup CFA was performed. SAVE-6 showed high internal consistency, α = 0.89 and ω = 0.92, a minimum score of 12, a maximum score of 22, an unifactorial structure, and adequate convergent validity. Specifically, the following were found: the positive and significant relationship with HADS was 0.98 for the full scale, 0.76 for depression, and 0.91 for anxiety, and there was a negative and significant convergent validity with resilience (-0.82) and resilience to suicide attempts (-0.88). Regarding the gender invariance, relevant data is that the factor loadings between each item and the SAVE-6 factor were not the same, so women present a higher level of anxiety than men (Δχ 2 (6) = 42.53). The results showed good internal reliability of SAVE-6 and good suitability. Data also revealed that they were not equal in relation to gender. Specifically, the scalar invariance revealed significant differences by items between men and women in anxiety. This scale can be applied to medical students as a reliable and valid instrument to assess the anxiety response to disease contagion in future health professionals.
本研究旨在评估 SAVE-6 在医学生群体中的心理计量学特性，并评估其性别不变性。样本由 320 名年龄在 18-23 岁的医学生组成（男性 153 名，女性 167 名），他们完成了一份匿名在线问卷。数据收集于 2024 年 6 月进行。为了评估量表结构，对项目进行了描述性分析，随后进行了验证性因素分析（CFA）。为了分析测量的性别不变性是否存在差异，进行了多组 CFA。SAVE-6 表现出较高的内部一致性，α=0.89 和 ω=0.92，最小得分为 12，最大得分为 22，具有单因素结构和适当的聚合效度。具体而言，发现以下结果：与 HADS 的正相关且显著相关，全量表为 0.98，抑郁为 0.76，焦虑为 0.91，与韧性（-0.82）和对自杀企图的韧性（-0.88）呈负相关且显著。关于性别不变性，相关数据表明，每个项目与 SAVE-6 因子之间的因子负荷并不相同，因此女性的焦虑水平高于男性（Δχ 2 (6) = 42.53）。结果表明，SAVE-6 具有良好的内部可靠性和适宜性。数据还表明，它们在性别方面并不相等。具体而言，标量不变性表明，男性和女性在焦虑方面的项目存在显著差异。该量表可应用于医学生，作为评估未来卫生专业人员对疾病传染反应的可靠有效工具。
