Decision-Making Style: The Development and Assessment of a New Measure

A multistage, four sample study was conducted to develop a conceptually consistent and psychometrically sound measure of decision-making style. Construct definitions were developed from prior theory, and items were written to assess rational, avoidant, intuitive, and dependent decision-making styles. A series of principal-axis factor analyses with varimax rotation and subsequent item analyses were conducted to develop four conceptually distinct scales with acceptable internal consistency (alpha ranging from .68 to .94) and a stable factor structure. In the process of scale development, a fifth style (spontaneous) was identified. Tests for independence among the five decision-making style scales and concurrent validity analyses were conducted. Finally, discussion of the new instrument with reference to the extant literature is provided.
