Motivation Insights® 2021 Reliability Study
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.
