The Basadur simplex creative problem-solving profile inventory: development, reliability and validity

Abstract

<p>The underlying theory and early development and internal consistency testing of the Basadur CPSP (Creative Problem Solving Profile) inventory is reviewed, then new expanded reliability and validity research is summarized. The four columns, the four quadrants, and the two bi-polar scales of the CPSP demonstrated satisfactory reliability via test-retest, independence of scales, and parallel split-half correlations.</p> <p>The CPSP correlated with the Kirton Adaptation I nventory (KAI) and the Myers-Briggs Type I ndicator (MBTI) in predicted ways. Also, the relative impact of creativity training was moderated according to CPSP style in expected ways. Assessments of CPSP style by self alone and in consensus with expert partner significantly agreed with the assessments made by the inventory itself. Predictions of field of endeavor (occupation) and of level of organizational responsibility for strategic thinking by preferred CPSP style and preferred ratio of ideation-evaluation polar opposites were strongly supported. Opportunities for improving psychometrics, especially reliability, are identified.</p>
