Abstract
Background. Individual techniques, or decision-making styles, are included in the regulation of hierarchies of processes that mediate a person’s exit from situations of uncertainty. Diagnostics of these styles helps both to solve practical problems and to clarify theoretical issues — in particular, the issue of the generalization of styles and their connections with the intellectual and personal spheres. Objective. The aim is to test and adjust the General Decision-Making Style Inventory questionnaire to a Russian sample. Study Participants. 456 people aged 18 to 50 years (M = 24.80; SD = 7.61); of these, 74 were men (M = 22.96; SD = 4.88) and 358 were women (M = 25.25; SD = 8.08), 24 subjects did not indicate gender. 80% were university students, 20% were working employees. Methods. The study included 3 stages: translation, assessment of structural validity and reliability on a Russian sample, assessment of convergent validity. 4 questionnaires were used: the General Decision-Making Style, Rational-Experiential Inventory, Personal Factors of Decision Making (PFDM), Impulsivity-7. Results. A structural model of connections between the scales (factors) of the General Decision-Making Style Questionnaire has been constructed. The model demonstrated good fit to the data and Cronbach's alpha reliability coefficients were acceptable (0.75 to 0.85). The convergent validity of the questionnaire scales was confirmed. Analysis of differences by gender revealed significantly higher scores for Intuitive and Dependent styles in women. Conclusions. The General Decision-Making Styles Questionnaire has a 5-factor structure and acceptable psychometric properties. Convergent validity has been demonstrated primarily for the Rational and Intuitive styles when identifying their connections with other similar constructs. Both styles are not related to each other, but are related in the opposite way to the Spontaneous (Impulsive) style.
