Instructions

Rate how much you agree with each statement about yourself. Answer honestly based on how you really think and behave, not how you'd like to be. This is a research-style trait measure for self-reflection — there are no right or wrong answers.

Construct and item content adapted from the Dirty Dozen (Jonason & Webster, 2010). Items are close rewordings of the original statements, and the response format is changed from the published 9-point scale to 5-point; original paper cited. Raw scores therefore contrast with published norms — use the bands shown here.
