The purposes of this study were: (1) to adapt the Consensual Technique for Creativity Assessment (Amabile, 1982; 1983a) methodology for use in the domain of interior design; and (2) to provide evidence for reliability and construct validity of the methodology.

Participants were subjects who created the 18 projects used in the study, and judges, the 44 professional interior design experts who rated the projects. The sample of subjects was comprised of interior design students at a FIDER-accredited institution in the Mid-Atlantic region. The judges sample included two sub-categories: Educators (13) who were Corporate members of IDEC; and Designers (31) who were Professional members of ASID.

Projects were assessed by subjective ratings on the Dimensions of Judgment for Interior Design creativity, the list of 12 rating criteria adapted from Amabile. Ratings were collected in judging sessions at three regional sites.
