Appendix A: Standardization, Reliability, and Validity Tables

Table A.11. Internal Consistency: EQ-i 2.0 Normative Sample

The following table summarizes the internal consistency (Cronbach’s alpha) values for the EQ-i 2.0 Total EI score, composite scales, and subscales in the EQ-i 2.0 normative groups. Alpha values range from 0.00 to 1.00. Higher values, like those found in the EQ-i 2.0 normative sample, provide evidence for strong reliability..
