BACKGROUND Workplace bullying is considered a major social stressor at work. However, in the Spanish context, there is a lack of measures that allow researchers and practitioners to distinguish between non-targets and targets of workplace bullying. METHOD This study reports the psychometric properties, factor structure, and cutoff scores for the Short-Negative Acts Questionnaire (S-NAQ) in a Spanish sample (N = 1,409). RESULTS The S-NAQ demonstrated adequate psychometric properties. Moreover, both Exploratory and Confirmatory Factor Analysis revealed that a unifactorial model of workplace bullying fit the data best. Two cutoff points for the S-NAQ were formulated using receiver operating characteristic curves to categorize respondents as "not exposed to workplace bullying" (scores below 15), "at risk of being bullied" (scores between 15 and 22), and "targets of workplace bullying" (scores above 22). CONCLUSIONS These cutoff scores may help researchers and practitioners in diagnosing workplace bullying and designing intervention strategies.

工作场所欺凌的临界值：西班牙短期负面行为调查表（S-NAQ）。

背景技术工作场所欺凌被认为是工作中的主要社会压力源。但是，在西班牙语环境中，缺乏使研究人员和从业人员能够区分非目标和工作场所欺凌目标的措施。方法这项研究报告了西班牙样本（N = 1,409）中的短期负面行为调查表（S-NAQ）的心理计量学特性，因子结构和截断分数。结果S-NAQ表现出足够的心理计量特性。此外，探索性和确认性因素分析均显示，工作场所欺凌的单因素模型最适合该数据。S-NAQ的两个临界点是使用接收者的工作特征曲线制定的，将受访者归类为“没有受到工作场所欺凌”（得分低于15），“有被欺凌的危险” （得分在15到22之间）和“工作场所欺凌目标”（得分在22以上）。结论这些临界值可以帮助研究人员和从业人员诊断工作场所霸凌和设计干预策略。
