In a new thread, study the following descriptions of two tests and answer the two questions that follow the test descriptions. Then post a reply to a classmate.

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 subscales (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. Reliablity: 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. Please post your responses to the following questions:  a. Given this technical information, which of the above instruments would you select? b. What additional information would you want to have to make your decision?
