摘要：

The purpose of this study was to examine the effects on Cronbach coefficient alpha, an estimate of internal consistency reliability, of altering the number and type of item-response choices on measures administered to two independent samples (ns, 492 and 730). An increase in the number and type of response choices (from true/false format to four-choice Likert-type format) significantly increased the internal consistency reliability estimate.
