Abstract:
Abstract 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 α = .58 (modesty) to α = .87 (spirituality) in Sample 1 and α = .63 (honesty) to α = .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.
