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 EQ technical manual contains information on the history and development of emotional intelligence from its beginnings to the current implementation of the concepts as psychometric assessments. Included in this manual are a host of statistical and psychometric analyses used to establish evidence of the validity and reliability of the TTI Success Insights EQ assessment. Version 1.2 includes adaptation analyses for the United Kingdom and Australian versions, as well as analysis for the German EQ adaptation.
The 2017 Style & 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 Style Insights are labeled Dominance, Influence, Steadiness, and Compliance. The scales for the Motivation Insights are labeled Theoretical, Utilitarian, Aesthetic, Social, Individualistic, and Traditional.

In many cases, organization such as the American Psychological Association, provide general guidelines without providing specific guidance. As an example, we discuss the concepts of acceptable levels of reliability coefficients, as measured by the so-called “alpha” coefficients where after several decades there remains a lack of consensus.
