最初的优势行动价值量表（VIA-IS）是一个国际性的240项自我报告问卷，用于测量性格优势。一个经过验证和可靠的英语120项简表（VIA-120）是可用的。然而，关于德国VIA-120的心理测量特性的信息有限。本文解决了这一差距，并报告了德国VIA-120与德国VIA-240版本的可靠性，有效性和可比性。招募了两个独立的样本：一般人群样本（N = 1073，样本1）和由医学生和医生组成的样本（N = 685，样本2）。VIA-120量表的内部一致性在样本1中从α = 0.58（谦虚）到α = 0.87（灵性），在样本2中从α = 0.63（诚实）到α = 0.90（灵性）。120项版本和原始240项版本（样本1）的量表之间的相关性范围从r = .52（希望）到r = .89（谨慎）。用生活满意度量表（SWLS）和繁荣简明量表（BIT）验证效标效度。原始形式和简化形式之间的因子结构的比较显示出良好的收敛性（Tucker Φ.93-.99样本1，.95-.98样本2）。总体而言，德国VIA-120是可靠的，显示出良好的收敛与德国VIA-240，从而提出了类似的水平的有效性评估的性格优势。这项研究首次表明，VIA 120简表在有效性和可靠性方面与原始VIA 240条目版本相当，表明其有可能用于大规模研究。
The original Values in Action Inventory of Strengths (VIA-IS) is an international 240 item validated self-report questionnaire measuring character strengths. A validated and reliable English 120-item short form (VIA-120) is available. However, there is limited information about the psychometric properties of the German VIA-120. This article addresses this gap and reports the reliability, validity and comparability of the German VIA-120 with the German VIA-240 version. Two independent samples were recruited: a general population sample (N = 1073, Sample 1) and a sample consisting of medical students and physicians (N = 685, Sample 2). Internal consistency of the VIA-120-scales ranged from alpha = .58 (modesty) to alpha = .87 (spirituality) in Sample 1 and alpha = .63 (honesty) to alpha = .90 (spirituality) in Sample 2. Intercorrelations between the scales of the 120-item version and the original 240-Items version (Sample 1) ranged from r = .52 (hope) to r = .89 (prudence). Criterion validity with the Satisfaction with Life Scale (SWLS) and the Brief Inventory of Thriving (BIT) was demonstrated. The comparison of the factor structure between the original and the short form showed a good convergence (Tucker's Phi .93-.99 Sample 1, .95-.98 Sample 2). Overall, the German VIA-120 was reliable, showed good convergence with the German VIA-240 and thus presents a similar level of validity for the assessment of character strengths. This study provides the first indication that the VIA 120 short form is comparable regarding the validity and reliability of the original VIA 240-item version indicating its potential to be used in large scale research studies.
