The Impact of Event Scale (IES, Horowitz, 1979) has been widely used to evaluate subjective stress following traumatic life events. Based on the theoretical reflections of the authors, it consists of two subscales: intrusion and avoidance. Although the empirical data of the past 30 years have supported the original two-factor model to a large extent, alternative models have also been published. Our aim was to evaluate the psychometric properties of the Impact of Event Scale Hungarian version.
Data from 244 undergraduate students on the Hungarian version of Impact of Event Scale (Annus, Perczel Forintos, Kiss, 2005) were analyzed. Subjects were asked to fill in Beck Depression Inventory shortened version (Beck & Beck, 1972, Kopp & Forizs, 1993) and STAI-T (Spielberger, 1970, Sipos & Sipos, 1978) too.
Internal consistency of the whole IES (Cronbach's a=0,891) as well as of intrusion (Cronbach's a=0,874) and avoidance (Cronbach's a=0,818) was found to be very good. Test-retest reliability of the whole scale (r=0,491, p<0,001) as well as of subscales (for intrusion r=0,543 p<0,001, for avoidance r=0,523 p<0,001) was satisfactory. No association was found between gender and IES scores. Confirmatory and explanatory factor analysis supported the two factor model in our sample. IES had a moderate positive correlation with depression (r=0,273, p<0,001) and anxiety (r=0,381, p<0,001), indicating that it reflects a somewhat related but still independent construct.
The Hungarian version of the Impact of Event Scale has been proved a valid and reliable measure of post-traumatic stress symptoms.
事件影响量表（IES，霍洛维茨，1979年）已被广泛用于评估创伤性生活事件后的主观压力。基于作者的理论思考，它由两个子量表组成：侵入和回避。尽管过去30年的实证数据在很大程度上支持了最初的双因素模型，但也有其他模型发表。我们的目的是评估事件影响量表匈牙利语版本的心理测量特性。
分析了244名本科生关于事件影响量表匈牙利语版本（安努斯、佩尔采尔·福林托斯、基斯，2005年）的数据。受试者还被要求填写贝克抑郁量表简版（贝克和贝克，1972年，科普和福里兹，1993年）以及状态-特质焦虑量表（斯皮尔伯格，1970年，西波斯和西波斯，1978年）。
发现整个IES的内部一致性（克朗巴赫α系数=0.891）以及侵入（克朗巴赫α系数=0.874）和回避（克朗巴赫α系数=0.818）的内部一致性都非常好。整个量表的重测信度（r=0.491，p<0.001）以及子量表的重测信度（侵入r=0.543，p<0.001，回避r=0.523，p<0.001）都令人满意。未发现性别与IES得分之间存在关联。验证性和解释性因素分析支持我们样本中的双因素模型。IES与抑郁（r=0.273，p<0.001）和焦虑（r=0.381，p<0.001）呈中度正相关，表明它反映了一个有点相关但仍然独立的结构。
事件影响量表匈牙利语版本已被证明是一种有效且可靠的创伤后应激症状测量工具。
