Career decision-making continues to be a large area of research in the field of vocational psychology, particularly the factors that influence how one makes a career decision. To date, there have been no peer-reviewed quantitative studies that examine the impact that relationships have on career decision-making. The purpose of this study was to examine a hypothesized model predicting the relationships between career decision-making and belongingness, a form of relatedness. Participants included 436 college students at an urban university, who completed measures of belongingness, psychological distress, academic motivation, and career decision-making difficulties. The results of this study imply that the hypothesized model is a good fit and accounts for a large portion of the variance. It appears that when belongingness is viewed in subcategories, family and peer, there are two different outcomes. Family belongingness had a significant relationship with all other variables that were measured, while peer belongingness was not significantly related to any variable other than family belongingness. The results of this investigation indicate that family belongingness specifically has a powerful relationship with career decision-making difficulties. This provides significant implications for the field of vocational psychology and future research.
