The Supplemental Behavior Style Quick Reference Card is a 2-sided, tear and waterproof 8.5″ x 11″ card designed to be used in addition to the Behavior Style Quick Reference Card. It provides immediate, easy access to a summary of information related to reading Behavior Styles in others and 21 questions, anyone of which are especially helpful in giving you information to identify the Style of others. (This replaces the Quick Reference Guide, which is no longer available.)
