The network structure of the VIA-120 inventory of strengths: an analysis of 1,255,248 respondents

Traditional factor analyses used to analyze the structure of psychological strengths have yielded different solutions, not always confirming the original structure of 24 strengths corresponding to six virtues as proposed by Peterson and Seligman in their initial model. In contrast with previous factorial approaches, this study used network analysis to explore the map of strengths, assessed with the VIA Inventory of Strengths (VIA-IS), in a large sample of individuals (N = 1,255,248) from the general population in the United States, Australia, Canada, and UK. The network analysis revealed four different communities (i.e., groups of strengths): Discernment, Interpersonal, Responsibility, and Energy. The strength most connected to other strengths was Gratitude, whereas Love of Learning was the least connected node. These results open a new way to conceptualize psychological strengths as a complex network of mutually interconnected strengths. These findings complement results from factor analyses that future research should replicate and validate.
