The purpose of this study was to use a meta-analytic method known as reliability generalization to investigate the score reliability for a popular depression measure: The Reynolds Adolescent Depression Scale. We used the technique to provide an aggregate estimate of coefficient alpha across empirical studies that have employed the measure over time and across populations. Furthermore, we identified sample and demographic characteristics associated with variance in coefficient alpha. We discuss conditions associated with variability in coefficient alpha and alert researchers and practitioners to appropriate uses of the scale based on common reliability benchmarks.
