Analysis of the psychometric properties of the Melbourne Decision Making Questionnaire in Colombian adolescents / Análisis de las propiedades psicométricas del Melbourne Decision Making Questionnaire en adolescentes colombianos

ABSTRACT

Abstract Background/objective: Decision-making is a set of skills useful for daily functioning which allow people to perform their tasks and control objectives and goals, generating responses to the environment's demands from their resources. Research and intervention with adolescents require reliable instruments to assess decision-making. The Melbourne Decision Making Questionnaire (MDMQ) is an instrument that assesses decision-making styles and has been successfully validated in different cultural contexts. This study analysed the psychometric properties, construct validity (factorial, convergent, and discriminant), and predictive validity of the MDMQ in Colombian adolescents. Method: A cross-sectional study was conducted in which 822 adolescents aged 14 to 18 years (M = 16.09, SD = 1.31, 33.7% girls), 410 from the regular school system (M = 15.50, SD = 1.29, 48.54% girls) and 412 adolescents from the Criminal Responsibility System (M = 16.6, SD = 1.04, 18.93% girls) participated. Decision-making styles, emotional intelligence, cognitive distortions, prosocial behaviour and antisocial behaviour were assessed. Confirmatory Factor Analysis (CFA), reliability, correlational and predictive analyses were performed. Results: The CFA showed satisfactory fit indices for the original model of four factors and 22 items. Sufficient reliability conditions were observed. The results indicated that rational decision-making (vigilance) is positively associated with emotional intelligence and influences prosocial behaviour. Negative decision-making styles are associated with cognitive distortions and influence antisocial behaviour. Conclusions: After analysing the psychometric properties, it is concluded that the MDMQ is a valid instrument to assess the decision-making styles of Colombian adolescents.

RESUMEN

Resumen Antecedentes/objetivo: La toma de decisiones es un conjunto de habilidades útiles para el funcionamiento diario que permite a las personas realizar sus tareas y controlar objetivos y metas, generando respuestas a las demandas del entorno a partir de sus recursos. La investigación y la intervención con adolescentes requieren instrumentos fiables para evaluar la toma de decisiones. El Melbourne Decision Making Questionnaire (MDMQ) es un instrumento que evalúa los estilos de toma de decisiones y ha sido validado con éxito en diferentes contextos culturales. Este artículo analizó las propiedades psicométricas, la validez de constructo (factorial, convergente y discriminante) y la validez predictiva del MDMQ en adolescentes colombianos. Método: Se realizó un estudio transversal en el que participaron 822 adolescentes de 14 a 18 años (M = 16.09, DT = 1.31, 33,7% chicas), 410 del sistema escolar (M = 15.50, DT = 1.29, 48.54% chicas) y 412 adolescentes del Sistema de Responsabilidad Penal (M = 16.6, DT = 1.04, 18.93% chicas). Se evaluaron los estilos de toma de decisiones, la inteligencia emocional, las distorsiones cognitivas, la conducta prosocial y la conducta antisocial. Se realizaron análisis factoriales confirmatorios (AFC), análisis de fiabilidad, correlacionales y predictivos. Resultados: El AFC mostró índices de ajuste satisfactorios para el modelo original de cuatro factores y 22 ítems. Se observaron condiciones de fiabilidad suficientes. Los resultados indicaron que la toma de decisiones racional (vigilancia) se asocia positivamente con la inteligencia emocional e influye en el comportamiento prosocial. Los estilos negativos de toma de decisiones se asocian con las distorsiones cognitivas e influyen en el comportamiento antisocial. Conclusiones: Después de analizar las propiedades psicométricas, se concluye que el MDMQ es un instrumento válido para evaluar los estilos de toma de decisiones de los adolescentes colombianos.
