VIA Character Strengths
A classification of 24 positive personality traits grouped into 6 virtues, measured by the free VIA Survey developed by psychologists Christopher Peterson and Martin Seligman.
The VIA Classification groups 24 character strengths, like curiosity, kindness, and self-regulation, under 6 broader virtues: wisdom, courage, humanity, justice, temperance, and transcendence. Christopher Peterson and Martin Seligman developed it in the early 2000s as a positive counterpart to clinical diagnostic manuals, cataloging what's right with people instead of what's wrong.
The free VIA Survey measures all 24 strengths with around 240 rating-scale items, roughly 10 per strength, and takes about 10 to 15 minutes. Unlike the Big Five, it doesn't score traits on a bad-to-good spectrum, everyone has all 24 strengths in some order, ranked from most to least characteristic.
