Left-wing authoritarianism is a multidimensional construct that is gaining increasing interest. This study evaluated the validity and reliability of three versions of the Left-Wing Authoritarianism Scale (LWA) among Chilean university students and proposed a shortened 9-item version (LWA-9) that significantly reduces the length of the instrument and facilitates its use in applied contexts.
A non-probabilistic convenience sampling method was used, involving 415 Chilean university students (69.2% women, 30.1% men, and 0.7% identifying as another gender), aged between 17 and 44 years ( = 20.06; SD = 3.42). Participants completed a sociodemographic questionnaire, the LWA scale, the Social Dominance Orientation scale (SDO-7), and the Right-Wing Authoritarianism scale (RWA). Exploratory Structural Equation Modeling (ESEM) analyses were conducted to evaluate the factorial structure.
Analyses confirmed a correlated three-factor structure for all versions. The LWA-9 version stood out for better psychometric fit, high factor loadings, robust reliability levels, and factorial invariance by sex up to strict invariance, although it only reached configural invariance by age group. Convergent validity was supported by positive and significant correlations with the SDO-7 dimensions, and discriminant validity by low and non-significant correlations with the RWA scale, indicating that the LWA-9 captures a distinct construct.
These results support the structural validity of the LWA in all its versions and its empirical utility as a brief, efficient, and theoretically sound measure of left-wing authoritarianism.
左翼威权主义是一个多维度的概念，正日益受到关注。本研究评估了智利大学生中三个版本的左翼威权主义量表（LWA）的有效性和可靠性，并提出了一个缩短为9个条目的版本（LWA - 9），该版本显著缩短了量表长度，便于在实际应用中使用。
采用非概率便利抽样方法，涉及415名智利大学生（69.2%为女性，30.1%为男性，0.7%为其他性别），年龄在17至44岁之间（平均年龄 = 20.06；标准差 = 3.42）。参与者完成了一份社会人口学问卷、LWA量表、社会支配取向量表（SDO - 7）和右翼威权主义量表（RWA）。进行探索性结构方程模型（ESEM）分析以评估因子结构。
分析证实了所有版本的相关三因素结构。LWA - 9版本在心理测量拟合度、高因子载荷、稳健的可靠性水平以及性别间直至严格不变性的因子不变性方面表现突出，不过按年龄组仅达到构型不变性。与SDO - 7维度的正向显著相关性支持了收敛效度，与RWA量表的低且不显著相关性支持了区分效度，表明LWA - 9捕捉到了一个独特的概念。
这些结果支持了LWA所有版本的结构效度及其作为一种简短、有效且理论上合理的左翼威权主义测量方法的实证效用。
