Abstract
The present article describes an evaluation of a self-report questionnaire administered to whole classrooms of 7th graders. Using the test-retest reliability matrix (based on concepts of Cronbach [1] and Campbell and Fiske [2]), eight of nine drug-use indices appeared to have acceptable to good reliability. The three measures included in the test-retest reliability matrix provide stronger evidence for good reliability than could any single measure.
