Each domain draws two items from each of six * facets. 23 of the 60 items are reverse-keyed. Domain scores are * descriptive (12-60 each); no clinical cutoffs exist, so no bands are * defined. * * Facets are two items apiece — far too short to score on their own — * so psytools reports the five domains and documents the facet * composition in `meta.scoringNote`.
