Spanish validation of General Decision-Making Style scale: Sex invariance, sex differences and relationships with personality and coping styles

Abstract

AbstractThe General Decision-Making Styles (GDMS) scale measures five decision-making styles: rational, intuitive, dependent, avoidant and spontaneous. GDMS has been related to coping and some personality factors and sex-differences has been described. In spite of its usefulness, there is not a validated Spanish translation. The aim of this study is to translate to Spanish and provide psychometric evidence considering sex differences and the relationships between GDMS, personality and coping variables. Two samples were used for this study; the first sample composed by 300 participants who completed the GDMS and the Rational-Experiential Inventory (REI), and the second sample of 361 participants who completed the GDMS, the Ten Item Personality Trait Inventory and the brief COPE scales. Participants from second sample filled in GDMS a second time (137 participants) after eight weeks from the first data collection. Confirmatory factor analyses showed a five-factor composition of GDMS with equivalence across sex using invariance analyses. Moreover, GDMS showed acceptable internal consistency and temporal stability. Finally, rational and intuitive styles were related to healthier coping patterns and emotional stability, while dependent, avoidant and spontaneous styles were associated with unhealthy coping patterns and emotional instability.
