The Thomas-Kilmann Conflict Mode Instrument (TKI) has been used for 40 years and is the leading measure of conflict-handling behavior. In 2002, the TKI assessment became available via the Internet using CPP’s online assessment delivery system, the SkillsOne® website. With online administrations, data are collected as part of CPP’s ongoing commercial operations.
Over time these operations created a large archive of completed TKI assessments, as well as a vast pool of participants from which a large representative norm sample could be developed. This has made it possible for CPP’s Research Division to develop updated norms for the instrument to use as the basis for scoring and determining results.
The updated norms, developed in 2007, were based on a sample of 4,000 men and 4,000 women, ages 20 through 70, who were employed full-time in the United States at the time they completed the assessment. Data were drawn from a database of 59,000 cases collected between 2002 and 2005 and were sampled to ensure representative numbers of people by organizational level and race/ethnicity.
This page contains the research to support the reliability and validity of the TKI tool, as well as best practices and industry trends when applying the assessment results in different settings. You will also find information on ways to pair the instrument with other assessments for maximum effectiveness.
