摘要:In light of the increasing amount of literature available in English regarding personal decision-making styles or patterns, we have adapted the Melbourne D.M.Q. by Leon Mann (1997) to our particular purposes. This questionnaire is itself a revised version of the Flinders D.M.Q. (1982), both instruments being based on the decisional conflict model proposed by Irving Janis and Leon Mann in 1977. Two studies were carried out with a threefold objective: (1) to validate our adaptation of Mann’s instrument (1982, 1997) from a psychometrical point of view; (2) to analyse, within our context, the similarities and differences between our own university students and those from other cultures as regards decision patterns and decision-making self-esteem; and finally (3), to study the possible relationship between decision patterns and conflict coping styles. Finally, the paper examines the theoretical implications of the aforementioned results.
