Abstract
Survey protocols measuring financial knowledge typically offer a don't know (DK) response option along with factual statements about personal finance. The potential problem of this practice is that a DK response could capture something other than financial knowledge and mislead empirical research on the association between financial knowledge and behavioral outcomes. In this study, we examined whether the current scales are contaminated by systemic personality effects and how reduced validity influences analytical modeling of the knowledge effect. Two studies with different national datasets were conducted in this investigation. Study 1 found that personality types and emotions are partially correlated with the propensity to give a DK response. Study 2 showed that controlling for DK response options alters the association between financial knowledge and behaviors in regression analyses. Our findings suggest that a DK response reduces construct validity of the financial knowledge score.
期刊介绍：
The ISI impact score of Journal of Consumer Affairs now places it among the leading business journals and one of the top handful of marketing- related publications. The immediacy index score, showing how swiftly the published studies are cited or applied in other publications, places JCA seventh of those same 77 journals. More importantly, in these difficult economic times, JCA is the leading journal whose focus for over four decades has been on the interests of consumers in the marketplace. With the journal"s origins in the consumer movement and consumer protection concerns, the focus for papers in terms of both research questions and implications must involve the consumer"s interest and topics must be addressed from the consumers point of view.
