The effect of item content overlap on Organizational Commitment Questionnaire–turnover cognitions relationships.

This study examined the effect of overlapping scale content when certain items in the Organizational Commitment Questionnaire (OCQ) are used to predict turnover cognition measures. Analyses of judgmental data collected from 25 subject matter experts suggested that 6 OCQ items reflected a desire or an intent to retain membership in one's organization. Confirmatory factor analyses of survey data from 172 master of business administration alumni showed that the 6 OCQ retention items shared overlapping content with turnover cognitions items. Hierarchical multiple regression analyses of survey data from 330 hotel managers showed that (a) removing the 6 OCQ retention items caused a significant decrease in the variance explained in a measure of turnover cognitions and (b) the size of this effect is larger than that suggested by previous work.
