The present study examined general Decision-making styles in relation to stress and anxiety among undergraduate and postgraduate students in Dublin. A sample of 125 students participated in this study, from various Dublin city centre-based colleges and universities. The study used Scott & Bruce’s General Decision-making Scale (GDMS) and Depression, Anxiety and Stress Scale (DASS-21), accompanied by two short demographic questions. Both scales displayed good internal consistency. The results of the study found that two decision-making styles (Rational and Avoidant decision-making style), significantly predicted anxiety and stress. Rational decision-making style was associated with a lower level of stress and higher level of anxiety, while Avoidant decision-making style was associated with a high level of anxiety. Additionally, Dependant decision-making was examined in relation to stress, however, there was no significant relationship found.
