Abstract
This study was designed to examine the level of dependence within multiple true‐false (MTF) test item clusters by computing sets of item intercorrelations with data from a test composed of both MTF and multiple choice (MC) items. It was posited that internal analysis reliability estimates for MTF tests would be spurious due to elevated MTF within‐cluster intercorrelations. Results showed that, on the average, MTF within‐cluster dependence was no greater than that found between MTF items from different clusters, between MC items, or between MC and MTF items. But item for item, there was greater dependence between items within the same cluster than between items of different clusters.
