The current content analysis examines work-family conflict (work-to-family conflict and family-to-work conflict) research published between January 2010 and December 2018. The bioecological theory was used as a conceptual framework to deductively develop and guide the content-coding of hypotheses/research questions. Fifty-eight empirical articles containing 196 hypotheses/research questions were included in the sample. Results indicate that the microsystem was examined more than other ecological systems, and demand characteristics were assessed more than resource or force characteristics of work-family conflict. In addition, among individuals' demand characteristics, age and gender were studied more than race in relation to understanding work-family conflict experiences. Taken together, these findings suggest that future work should focus on studying resource characteristics, demand characteristics, and and the influences of the exo-, macro-, and chronosystems that may better explain work-family conflict among employees in the United States.
