The Reliability and Validity of the Keirsey Temperament Sorter Among Physician Leaders

Little research exists on the psychometric properties of the Keirsey Temperament Sorter (KTS). This study examined the reliability and validity of the KTS among 70 physicians leaders. Respondents completed two administrations of the KTS 1-4 months apart and an MBTI and professional survey. The reliability (temporal stability) of the KTS was adequate for the E/I and T/F scales, but inadequate for the S/N and J/P scales. The concurrent validity (between KTS and MBTI) also reflected these results, implying that the validity may be adequate but limited by reliability. This study lacked the sample size to judge construct validity and selected subgroups. Until proven to possess adequate psychometric properties, the KTS should not be used an an educational metric.
