Overall score reporting

  • Investing
Scoring procedures

The measure is self-scored.

Interpretive information

Scores can be interpreted as indicating high, moderate, and low self-concept.

Evidence of Technical Quality
Populations for which technical quality evidence has been collected

Evidence is based on samples of students (~1000) from Florida and Oklahoma schools.

Reliability evidence

The split-half reliability estimate for the total score was estimated (0.93) (Purkey et al., 1973).

Validity evidence
Evidence based on content
A literature review to identify classroom behaviors associated with positive self-image was conducted. These items were then reviewed by elementary school teachers (Purkey et al., 1973).
Evidence based on response processes
No information is available in the references reviewed.
Evidence based on internal structure
Exploratory factor analysis was used to substantiate four factors (Purkey et al., 1973). KEY scores showed significant differences between disruptive and non-disruptive students (Branch, Purkey, & Damico, 1976).
Evidence based on relations with other variables
KEY scores differentiated between treatment and control students in an experiment evaluating the impact of a program designed to improve self-concept (Purkey, 1984).
