The dual-process framework proposes that there are two main orientations that affect goal development and management. We examined this framework as an explanatory model for the development of career calling, using a sample of young adults (N = 213, Mage 19.9 years). The model included goal orientation (assimilation and accommodation) as distal, trait-based characteristics influencing goal approach (engagement and disengagement), which, in turn, influences the development of a calling (an important domain-specific goal) and calling-related strategies (goal-implementation actions). The model was largely supported: Assimilation related positively to engagement and negatively to disengagement. Engagement related positively to calling and strategies, and engagement and disengagement mediated between assimilation and calling, explaining 45% of the variance in calling. Few studies have tested antecedents to career calling, meaning little research has focused on its development. This study illustrates a potential explanation for the development of a calling based on goal-setting and self-regulation approaches.
