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.
