To date, few studies have examined the dispositional antecedents of career adaptability and no studies have specifically explored whether these relationships operate similarly or differently across distinct groups of adult career transitioners. To address this gap, we had 298 young adults (i.e., college seniors or recent graduates poised to enter the workforce) and 169 older adults (i.e., workers who were either contemplating retirement or recently #retired) complete measures of adult attachment #orientations, career adaptability, life satisfaction, and life meaning. Results demonstrated that attachment security and career adaptability were associated in expected directions with, and explained unique variance in, each of our indicators of #subjective well-being, and that career adaptability scores mediated observed relations between adult attachment insecurity and transitioners’ well-being. Exploratory analyses further showed that, for both groups of transitioners, career concern and control strategies emerged as significant mediators of these
relationships. Future research directions and practical implications of our findings for counseling interventions with career transitioners are discussed.
