The following manual contains information on the history and development of the concept of motivation from its beginnings to current implementation of these concepts as psychometric assessments. Included in this manual are a host of mathematical, statistical, and psychometric analyses used to establish evidence of validity and reliability of the TTI Success Insights Motivation Insights assessment.
The 2021 Motivation Insights Reliability Study is an internal consistency reliability study and is part of TTI SI’s ongoing continuous improvement process. This study uses a measurement of reliability called the Cronbach’s α (alpha). Cronbach’s α is a measure of the lower bound estimate of the reliability of a psychometric assessment. Cronbach’s α is a scalar taking values between 0 and 1, inclusive. Generally speaking, the closer the score is to one, the more reliable an assessment may be considered. The scales for the Motivation Insights are labeled Theoretical, Utilitarian, Aesthetic, Social, Individualistic, and Traditional.
The 2021 Style Insights Reliability Study is an internal consistency reliability study and is part of TTI SI’s ongoing continuous improvement process. This study uses a measurement of reliability called the Cronbach’s α (alpha). Cronbach’s α is a measure of the lower bound estimate of the reliability of a psychometric assessment. Cronbach’s α is a scalar taking values between 0 and 1, inclusive. Generally speaking, the closer the score is to one, the more reliable an assessment may be considered. The scales for the Style Insights are labeled Dominance, Influence, Steadiness, and Compliance.

The following TTISI Style Insights Technical Manual Version 1.0 contains information on the history and development of our behavioral assessment, from its beginnings to current implementation. Included are a host of mathematical, statistical, and psychometric analyses used to establish evidence of validity and reliability of this TTISI assessment. The reader interested in all the details is encouraged to read the manual in its entirety. However, if the reader is interested in the final results, one should focus on Section 16, which serve as a summary of what has been presented elsewhere in this work as well as thoughts for future projects and studies. Appendix B, starting on page 176, presents results from our logistic regression approach to O’NET occupational title identification through the Style Insights variables.
