Test A: 40 items

Description: Measure of self-esteem

Scales: Total Score, General Self-Esteem, Social Self-Esteem, Personal Self-Esteem

Reliability: Test-retest r = .81; coefficient alphas for the Total Score, General Self-Esteem, Social Self-Esteem, Personal Self-Esteem scales are .75, .78, .57 and .72, respectively.

Validity: Content—developed construct definitions for self-esteem, developed table of specifications, wrote items covering all content areas, used experts to evaluate items. Convergent—correlated with Coopersmith's Self-Esteem Inventory r = .41. Discriminant—correlated with Beck Depression Inventory r =.05. Factor analysis revealed that the three sub scales (General Self-Esteem, Social Self-Esteem, Personal Self-Esteem) are dimensions of self-esteem. Homogeneity—correlations between the scales indicate the General scale correlated with the Social scale at .67, the Personal scale at .79, and the Total scale at .89.


Test B: 117 items

Scales: Global self-esteem, competence, lovability, likability, self-control, personal power, moral self approval, body appearance, body functioning, identity integration, and defensive self-enhancement.

Reliability: Test-retest for each scale ranges from .65 to .71. Coefficient alphas range on each scale from .71 to .77.

Validity: Content—based on a three-level hierarchical model of self-esteem. Convergent—correlated with the Self-Concept and Motivation Inventory r = .25 and with the Eysenck Personality Inventory r = .45. Discriminant—correlated with Hamilton Depression Inventory r = .19.
