An examination of the general decision making style questionnaire in two UK samples

Abstract

Purpose - To examine the psychometric properties and construct validity of the general decision making style (GDMS) questionnaire in two UK samples. Design/methodology/approach - The GDMS takes the form of a self-report questionnaire which identifies five decision making styles: Rational, intuitive, dependent, avoidant, and spontaneous. It was administered to samples of business studies undergraduates in two UK business schools. Analyses included scale reliabilities, test-re-test reliability, and both exploratory and confirmatory factor analyses. Findings - The instrument's internal and temporal consistencies were generally sound. Consistent with earlier studies, analyses undertaken on the two samples independently were generally supportive of a five factor model of decision making style. No relationships with gender or year of study were observed. Research limitations/implications - Whilst generally supportive of the GDMS, results suggest that further validation work is required. This could include consideration of the relationships between the GDMS and other measures of cognitive/personality style. Practical implications - The managerial implications of the strengths of and relationships between the different decision making styles observed are discussed. Originality/value - The paper fulfils a stated requirement for further validation study of the GDMS instrument. © Emerald Group Publishing Limited

“…Personal characteristics and individual differences affect general decision-making processes (Aminoff et al, 2012;Bazerman & Moore, 2013;Spicer & Sadler-Smith, 2005). As previously said, career decision-making processes are not only affected by one's educational background but also by role models (Flouri & Buchanan, 2002;Van Auken et al, 2006), self efficacy (Bandura, 1977;Bullock-Yowell, Andrews, & Buzzetta, 2011;Luzzo, 1993), and individual characteristics (Kidd, 1984;Law, 1981).…”

Impact of individual decision-making styles on marketing information system based decision-making

“…For instance, an individual characterized by a spontaneous decision-making style is inclined to make impulsive and "instant" decisions. Their desire to get through the decision-making process as quickly as possible (Spicer and Sadler-Smith, 2005) may jeopardize the quality of the decisions made. In order to lessen an impact of the human factor, a marketing information system should be constructed to eliminate the individual differences of decision-makers in terms of their decision-making styles.…”

“…Based on this, we can posit that individuals that fit under spontaneous decision-making style better handle marketing circumstances that require speedy decisions. Individuals in this style are characterized by a feeling of immediacy and the desire to get through the decisionmaking process as quickly as possible (Spicer and Sadler-Smith, 2005). Prior studies on decision speed view prompt action as a decisive competitive weapon for market innovation.…”

Based on the extant literature, a number of propositions have been developed with respect to the proposed relationships shown in the model below.…”

Making Sense of a Most Popular Metaphor in Management: Towards a HedgeFox Scale for Cognitive Styles

“…The influence of cognitive styles has become evident not only in relation to political judgment, as investigations have shown that the ways in which we perceive information and derive meaning from it are also relevant for decision-making, problem-solving, learning, creativity, and the support of different values (Hayes and Allinson 1998;Kirton 1976;Spicer and Sadler-Smith 2005;Puccio et al 1995;Tetlock 2000;Van Den Broeck et al 2003). …”
