摘要：This paper reports the results of a study designed to test the stability of responses to alternative versions of forced-choice questions. Six of the eight pairs of questions tested produced stable response patterns, but for two pairs of questions the alternative versions produced quite different results. In one case this could be explained by a subtle difference in question emphasis caused simply by reversing the choices presented; in the other, the apparent failure to present real alternatives was a possible explanation for the difference observed. The implication for questionnaire designers is that responses to alternative versions of forced-choice questions are generally stable, provided the choices presented are balanced and appropriately worded
