The Self-Esteem Index (SEI) is a multidimensional, norm-referenced measure of the way that individuals ages 7-0 through 18-11 years perceive and value themselves.

The SEI can be administered to individuals or groups in approximately 30 minutes. The self-report format requires subjects to read the SEI items and then to classify each item on a Likert-type scale as always true, usually true, usually false, or always false.

There are four scales on the SEI: Academic Competence, Family Acceptance, Peer Popularity, and Personal Security. Overall self-esteem is measured by the Self-Esteem Quotient. In addition, the four SEI scales each yield a standard score, and percentile ranks are provided.

Evidence of the reliability of the SEI is provided in the form of coefficients alpha computed at each 1-year age interval, all of which approach or exceed accepted standards.

Complete SEI Kit includes: Examiner’s Manual, 50 Student Response Booklets, and 50 Profile and Record Forms, all in a sturdy storage box. (1991)
