DECISION-MAKING STYLES AND SUBJECTIVE PERFORMANCE EVALUATION OF DECISION-MAKING QUALITY AMONG HOSPITAL NURSES
Languages of publication
The Melbourne Decision Making Questionnaire (MDMQ) is a widely used measure of decision-making styles (adaptive: vigilance; and maladaptive: hypervigilance, buck passing, and procrastination), but there is little evidence regarding its predictive ability in professional settings. The aim of the study was to assess the association between MDMQ dimensions and subjective performance evaluation of decision-making quality (SPEDM) among hospital nurses (N = 109). We also assessed whether MDMQ can predict variance in SPEDM when controlled for affective traits (neuroticism – BFI; and self-esteem – RSES), social desirability (MC–SDS10), and length of practice. Self-rated SPEDM was positively associated with vigilance, and negatively associated with maladaptive decision-making styles. Supervisor-rated SPEDM was unrelated to decision- making styles. Social desirability slightly affected the relationships between self-rated SPEDM and decision-making styles. Despite several limitations, the results cast doubt regarding the ability of the MDMQ to predict decision-making quality.
