Abstract
This study explores the relationship between decision-making style, as measured by the Melbourne Decision Making Questionnaire, and personality based on alternative five-factor model along with effect of age, sex and social position on such styles. A large sample of community and undergraduate students (n = 1,562; Mage = 40.03, SD = 18.43) was analyzed. The results showed that Neuroticism and Extraversion were significantly related to the non-vigilant styles Hypervigilance, Buck-passing and Procrastination. Women scored significantly lower in Vigilance and higher in Hypervigilance, Buck-passing and Procrastinations than men. Age was significantly related to decision-making style in a U-shaped fashion. The Social Position Index was significantly related to all decision-making styles. The most predictive personality domains regarding decision-making scales were Aggressiveness (negatively) and Activity for Vigilance, and Neuroticism for Hypervigilance, Buck-passing and Procrastination. Age, sex and social position had a small/medium overall effect on the four dimensions of Melbourne Decision Making Questionnaire (p < 0.001) with a η2 of 0.038, 0.068, 0.050, and 0.031 for Vigilance, Hypervigilance, Buck-passing and Procrastination, respectively. Based on scores on a single factor dimension of the MDMQ, the profile of participants with higher scores was characterized by lower age, more likely to be females, lower social position, higher levels of Aggressiveness, less Activity, less Extraversion, and higher Neuroticism.
Highlights
Making decisions involves choosing a course of action, a possibility derived from a judgment about a problem or a condition that demands a choice and is characterized by personal beliefs about what resources can allow someone to achieve their own goals (Baron, 2008). Janis and Mann (1977) suggested a theory about conflict and decision-making
Means and standard deviations are provided for age, Social Position Index (SPI), the domains of personality, and decision-making questionnaires (Table 1)
The SPI mean was 34.01 (SD = 18.64), which corresponds to an average social position rating (32–47 range) (Table 1 and Supplementary Table 1)

Decisionmaking is complex in its nature and planning and decisionmaking processes depend on different variables that contribute to whether they work out successfully or not. In this way, decision-making has been related in previous studies to different individual and psychological variables such as age, sex and personality (Bouckenooghe et al, 2007; Heidari and Arani, 2017; Filipe et al, 2020). It has been related to socioeconomic status (Sheehy-Skeffington, 2020)
