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.

Temporal consistency (a form of test-retest) is one of many forms of reliability that help establish an assessment as fully reliable and valid. This report of 7,742 individuals provides continuing evidence of temporal consistency, which adds to the argument that the TTI SI Styles Insights assessment has test-retest reliability.

This test-retest pilot study included 86 participants who took the behavioral assessment twice with an average separation of 38 days. The comparison showed no significant difference in the two reports and reliability was above 0.8 on both natural and adapted constructs.
