Understanding personality profiles can be helpful in working relationships. Situations such as co-teaching frequently pair individuals in teamwork. Turf and personality conflicts between professionals can be destructive and impede goal attainment. The Myers-Briggs Type Indicator (MBTI) is a personality measure that is based on Jung's theory of psychological types and has been established as having reasonable construct validity. The Richardson Inventory of Personality Types (RIPT) is likewise based on Jungian theory and contrary to the MBTI, utilizes a non-forced format and can be administered in a significantly reduced amount of time. The present study is a psychometric evaluation between the MBTI and the RIPT instruments. Both were administered to 210 participants enrolled in special education and speech/language and communication disorders courses at a state university. Results provided support for the construct validity and reliability of the RIPT and suggest utility in promoting understanding of personality profiles useful in situations requiring collaboration.
