Reliability Generalization as a Seal of Quality of Substantive Meta-Analyses: The Case of the VIA Inventory of Strengths (VIA-IS) and Their Relationships to Life Satisfaction.

Reliable test scores are essential to interpret the results obtained in statistical analyses correctly. In this study, we used the Values in Action Inventory of Strengths (VIA-IS) as an example of a widely applied assessment instrument to analyze its metric quality in what is known as reliability generalization (RG). In addition, we conducted a meta-analysis of the correlations between character strengths and life satisfaction to examine the potential relationship between the reliability of test scores and the intensity of these correlations.
