Description

This study revised vitality scale (VS) and examined its reliability and validity with 510 undergraduates. Exploratory factor analysis of thirty-six items and confirrmed factor analysis of eighteen parceled variables revealed the VS consisted of six factors: Vigor, flexibility, social withdrawal, activeness, mental toughness, and positiveness. Six subscales for these factors had sufficient internal consistency (α = .650 ‒ .917). To examine the validity of the VS, self-esteem scale and authenticity scale were modeled into the measurement model of these six factors. Significant path coefficients from self-esteem and authenticity to six factors were estimated. Its construct and concurrent validity was demonstrated in terms of the relationships with self-esteem and authenticity.
