This study used a within-participant design to evaluate the concurrent validity and test-retest reliability of the Violent Ideations Scale in a general population, English-speaking opportunistic sample. Data from 116 adult participants ( age = 33.7, = 11.9, male = 30 [25.9%]) were used to compare scores on the Violent Ideations Scale and Aggression Questionnaire and responses to the Schedule of Imagined Violence. A subgroup of 27 participants ( age = 37.2, = 13.6, male = 8 [29.6%]) completed the Violent Ideations Scale on a second occasion, 2 weeks later. The Violent Ideations Scale was found to correlate significantly with the Aggression Questionnaire subscale and total scores, with the strongest correlations being with physical aggression and total scores. Participants were more likely to be categorized as having experienced a violent ideation based on responses to the Violent Ideation Scale, compared with the Schedule of Imagined Violence, most likely due to the Schedule of Imagined Violence underestimating the prevalence of violent ideation. A significant, strong correlation was found between total Violent Ideations Scale scores at Time 1 and Time 2. Overall, the Violent Ideations Scale was found to have concurrent validity when compared with the Aggression Questionnaire and good test-retest reliability, suggesting that it would be suitable for use with a nonclinical, English-speaking sample.
本研究采用被试内设计，在讲英语的普通人群机会样本中评估暴力观念量表的同时效度和重测信度。来自116名成年参与者（年龄 = 33.7，标准差 = 11.9，男性 = 30人[25.9%]）的数据被用于比较暴力观念量表和攻击问卷的得分，以及对想象暴力量表的反应。27名参与者（年龄 = 37.2，标准差 = 13.6，男性 = 8人[29.6%]）组成的一个亚组在两周后第二次完成了暴力观念量表。结果发现，暴力观念量表与攻击问卷分量表及总分显著相关，其中与身体攻击和总分的相关性最强。与想象暴力量表相比，基于暴力观念量表的反应，参与者更有可能被归类为经历过暴力观念，这很可能是因为想象暴力量表低估了暴力观念的患病率。在第一次和第二次测量时，暴力观念量表总分之间发现了显著且强烈的相关性。总体而言，与攻击问卷相比，暴力观念量表具有同时效度，且重测信度良好，这表明它适用于非临床的讲英语样本。
