The article by Conger, Conger, and Martin reviews the relationship between socioeconomic status (SES) and family processes, focusing on the mechanisms that link SES to the quality and stability of romantic relationships and the development of children. The review highlights the support for an interactionist model that incorporates both social causation and social selection perspectives. Economic changes in the early 2000s, marked by financial distress and rising unemployment, have significantly impacted families, particularly those from minority backgrounds. The study emphasizes the importance of SES indicators such as income, education, and occupation in predicting family outcomes. The Family Stress Model (FSM) is discussed as a key theoretical framework, explaining how economic hardship leads to increased marital conflict and instability, and how this, in turn, affects children's development through disrupted parenting. The Investment Model (IM) is also explored, suggesting that higher SES leads to greater parental investments in children's development, which in turn enhances their cognitive and social competencies. The review concludes by highlighting the need for future research to address methodological limitations and to explore more complex social arrangements beyond the traditional nuclear family.The article by Conger, Conger, and Martin reviews the relationship between socioeconomic status (SES) and family processes, focusing on the mechanisms that link SES to the quality and stability of romantic relationships and the development of children.
