Flinder's Decision-Making Questionnaire: Ukrainian-language adaptation and psychometric properties

Introduction. The problem of human decision-making has increased in importance because it is the process of choice that determines its behavior in modern complex and unstable conditions. Understanding decision-making strategies is important both for the development of cognitive sciences and psychology, and for solving practical tasks that range from optimizing management processes to solving personal problems. Research in this area can contribute to increasing the effectiveness of personal and professional strategies in various activities. Aim: to adapt and determine psychometric characteristics of the L. Mann & I. Janis Flinder's Decision-Making Questionnaire (DMQ) on a Ukrainian-language sample. Methods: S.G. Scott & R.A. Bruce Decision-Making Styles (adapted by A. Sinenko & O. Savchenko), P. Steel Pure Procrastination Scale (adapted by O. Zhuravlyov), Rational Thinking (V. Gorai, O. Savchenko, 2022), A.M. O'Connor Decision Conflict Scale (adapted by L. Kolesnichenko & A. Homeniuk), Locus of Control (modification by O. Ksenofontova). Results: 1) the L. Mann & I. Janis DMQ was adapted for the Ukrainian-speaking sample; 2) the main psychometric indicators were determined, test norms were developed, and an interpretative scheme of the main indicators of the Short Flinders Decision-Making Questionnaire was proposed. Conclusions: the Ukrainian-language adaptation of the L. Mann & I. Janis DMQ is suitable for psychological assessement of individuals' decision-making strategies and can be used for scientific and applied purposes in various fields of psychology.
