Decision‐making collaboration scale: Tests of validity

Abstract
A trait Decision‐Making Collaboration Scale was discussed and examined for reliability and validity. The scale represents on‐going scale development to measure decision‐making tendencies. The premise is that individuals are generally willing or not willing to participate collaboratively in decision‐making communication interpersonally. The 13‐item measure is described. Support for validity was addressed by investigating the relationships between the decision‐making construct with argumentativeness, verbal aggression, interpersonal communication competence, and willingness to communicate. Willingness to participate in collaborative decision making was moderately related to argumentativeness, competence, and willingness to communicate in a positive manner, while slightly related to verbal aggression in a negative manner. Some construct validity was offered by asking participants to report their decision‐making tendencies and comparing these reports to their friends’ ratings of them. No significant differences were found. Implications for future research are discussed.
