Impulsivity is an important mental health-related variable that has been associated with various human behaviors. The Barratt Impulsiveness Scale is the most frequently used measure to examine impulsivity. However, its psychometric and factor structure was not examined in Arabic speaking population. The goal of the current study was to examine the psychometric properties and factor structure of the Barratt Impulsiveness Scale in Arabic speaking population. The current study used a cross-sectional design. Two independent samples were recruited: college students (N = 250) and persons with heart failure (N = 165). Exploratory factor analysis, then a series of confirmatory factor analyses were used to assess one- and three-factor models of the Barratt Impulsiveness Scale (30 items; i.e., BIS-11) and Barratt Impulsiveness Scale (15 items; i.e., BIS-15). Because our analysis did not support the factor structure of the previous versions of the Barratt Impulsiveness Scale, we used confirmatory factor analysis to evaluate the model structure of the single-factor measure. To assess the measurement invariance, the newly developed measure was examined across different genders and populations. Due to poor psychometrics of BIS-11 and BIS-15, a short form (BIS-SF) was developed; and validity, reliability, and measurement invariance were supported. The current analysis showed that BIS-11 and BIS-15 have poor psychometrics. Thus, there was a need to improve the measure by reducing the number of items and re-evaluating the psychometrics of the new measure. The BIS-SF is a reliable, valid tool to assess impulsivity in our samples. Other studies need to support the current study findings in populations with other chronic illnesses.
冲动性是一个重要的与心理健康相关的变量，与各种人类行为有关。巴瑞特冲动量表是最常用于检查冲动性的测量工具。然而，它的心理测量学和因子结构在讲阿拉伯语的人群中并没有被检验过。本研究的目的是检验巴瑞特冲动量表在讲阿拉伯语人群中的心理测量学特性和因子结构。本研究采用了横断面设计。招募了两个独立的样本：大学生（N=250）和心力衰竭患者（N=165）。使用探索性因素分析，然后进行一系列验证性因素分析，以评估巴瑞特冲动量表（30 项；即 BIS-11）和巴瑞特冲动量表（15 项；即 BIS-15）的单因子和三因子模型。由于我们的分析不支持巴瑞特冲动量表以前版本的因子结构，我们使用验证性因素分析来评估单因子测量的模型结构。为了评估测量的不变性，新开发的测量工具在不同性别和人群中进行了检验。由于 BIS-11 和 BIS-15 的心理测量学性能较差，因此开发了一个简短形式（BIS-SF）；并支持了有效性、可靠性和测量不变性。目前的分析表明，BIS-11 和 BIS-15 的心理测量学性能较差。因此，有必要通过减少项目数量和重新评估新测量的心理测量学来改进该测量工具。BIS-SF 是一种可靠、有效的工具，可以评估我们样本中的冲动性。其他研究需要在患有其他慢性疾病的人群中支持本研究的发现。
