Two types of questionnaire formats' measuring leadership variables were examined: one with items measuring the same dimensions grouped together and the second with items measuring the same dimensions distributed randomly. The random condition showed superior convergent and discriminant validity, as assessed by multitrait-multimethod and analysis…

This study provides support for the hypothesized effect of leniency on the discriminant validity of grouped questionnaire items. It was found that controlling for leniency resulted in a slight decrement in convergent validity but that discriminant validity was substantially improved. Implications for questionnaire validity and further research are…

Effects of item presentation mode on degree of leniency bias in responses to field research questionnaires were studied. Two modes were examined: first with items measuring the same dimensions grouped together and second with such items distributed randomly. The random mode showed substantially less leniency response bias. (Author/BW)

The empirical evidence does not support the prevailing conventional wisdom that it is advisable to mix positively and negatively worded items in psychological measures to counteract acquiescence response bias. An experiment, evaluating subjects' ability to respond accurately to both positive and reversed items on a questionnaire, analyzed post-hoc…

LISREL maximum likelihood confirmatory factor analyses assessed the effects of grouped and random formats on convergent and discriminant validity of two sets of questionnaires--job characteristics scales and satisfaction measures--each administered to 80 college students. The grouped format was superior, and the usefulness of LISREL confirmatory…

Three studies explored the effects of grouping versus randomized items in questionnaires on internal consistency and test-retest reliability with samples of 80, 80, and 100, respectively, university students and undergraduates. The 2 correlational and 1 experimental studies were reasonably consistent in demonstrating that neither format was…

Effects of item wording on questionnaire reliability and validity were studied, using 280 undergraduate business students who completed a questionnaire comprising 4 item types: (1) regular; (2) polar opposite; (3) negated polar opposite; and (4) negated regular. Implications of results favoring regular and negated regular items are discussed. (SLD)
