Effects of a substance abuse prevention program on the locus of control and self-concept of 148 Hispanic and Anglo third and fourth grade children were evaluated. A 2 x 2 (race x group) multivariate analysis of variance with repeated measures was carried out using the Health Resources Inventory, Coopersmith Self-Esteem Inventory, Nowicki-Strickland Locus of Control Scale, and two roster and rating sociometric questionnaires. The results of the analysis revealed a significant effect of time and interactions between time and race and time and group. Mean scores on the Health Resources Inventory and both sociometric questionnaires increased from pre-test to post-test for all children. In addition, children's scores indicated a change toward an internal direction on the Locus of Control Scale. Only the sociometric questionnaire measuring the children's perception of their popularity showed a significant group effect. The experimental group, those whose teachers had used the prevention curriculum, increased their perception of how well they were liked by their classmates. However, their actual popularity as measured by the average of their classmates' rating did not change. Possible explanations and methodological shortcomings are discussed.

This study examined the psychometric properties for the Draw-A-Person (DAP) test (Naglieri, 1988). Data were collected from 191 children following the accepted procedure from an earlier study (Badger & Jones, 1988). Drawings were scored using both Harris' (1963) and Naglieri's (1988) scoring systems following the procedures outlined in the manuals. Basically, the DAP test demonstrated reliable and valid properties. The Naglieri's (1988) scoring system was favored in this study because it demonstrated more consistent internal consistency, higher inter- and intra-rater reliability and satisfactory construct validity. Positive and moderate high correlations with the scores obtained from Goodenough-Harris's scoring systems supported that the Naglieri's version measured the same concept as the old system. Psychometric properties of the DAP test support use in clinical and research settings to gather data from children about their general abilities.
