Resumo(s)
The personal pattern of coping with the stress associated with making decisions characterizes the way an individual makes
choices and judgments. The Melbourne Decision Making Questionnaire (MDMQ) analyses these personal patterns and
has been used across various cultures in order to assess four main strategies: vigilance, buck-passing, procrastination, and
hypervigilance. We sought to adapt and validate a Portuguese version of the MDMQ. Our study was conducted with a sample
of 523 Portuguese people aged 18 or older. The questionnaire retained the original four scales, which represent four different
decisional patterns, showing good reliability and validity – concurrent as well as predictive – and invariance for gender and
age. The coping pattern with the highest mean was vigilance, while procrastination had the lowest mean. In contrast to other
studies of the MDMQ, our sample had a more diversified distribution of age. Young adults were less capable than older adults
of managing stress when making decisions, due to their higher levels of buck-passing, hypervigilance, and procrastination.
Vigilance showed stronger correlations to positive affect, satisfaction with life, and better decisional self-esteem, while the
remaining scales were related to negative affect, reduced decisional self-esteem, and lower satisfaction with life. These decisionmaking styles are chosen depending on time constraints, pressure, or other contextual characteristics. These results suggest
that individuals resort to more convenient patterns according to their situation, and that these patterns of decision-making can
be trained, developed, and improved.
