This study examined the relationships among three measurement methodologies that are used to assess characteristics and processes associated with creativity (i.e., a self-report questionnaire, teacher ratings, and a structured interview). In addition, we examined the predictive contributions of these three measurement methodologies for a divergent thinking test (Torrance Test of Creative Thinking-Figural; TTCT-F). Participants were 89 adolescents in the Midwestern United States. Results revealed that the self-report questionnaire and structured interview measure of self-efficacy correlated significantly (r = 0.34), but no other significant relationships among measurement methodologies were observed. Neither the self-report ratings nor teacher ratings significantly predicted performance on the TTCT-F, but the structured interview measures did.
