A conceptual model for informed actions driven by decision-making style and personality, corroborated by empirical evidence

Understanding how individuals take action is crucial for effectively explaining and influencing human behavior. Personality traits have long been established as significant determinants of behavior, and decision-making styles act as a vital bridge, mediating the relationship between personality traits while independently shaping these determinants. However, a critical gap remainsin models that explicitly connect personality types to action-oriented determinants. This study decisively addresses this gap by presenting a robust conceptual model that examines the relationship between personality types; NT, NF, SF, and ST and the COM-B components; Capability, Opportunity, and Motivation. The COM-B model has proven to be a powerful tool in implementation science for understanding individual actions and influencing key determinants. Developed through a thorough review of existing literature, the proposed model speculates that distinct personality types demonstrate either dominance or submissiveness across various COMB components, including capability (physical), capability (psychological), opportunity (physical), opportunity (social), motivation (automatic), and motivation (reflective). Empirical analysis, employing chi-square tests and logistic regression, corroborates these hypotheses using data from 44 individuals that capture personality traits and their connection to COM-B components. The findings reveal distinct patterns, notably that NT and NF individuals exhibit dominance in psychological capability, while SF and ST individuals are typically submissive. These results emphasize the critical role of personality in shaping individual actions and provide insights that extend beyond mere theoretical contributions.
