In this paper you will find a detailed exploration of the relationship between socioeconomic status (SES), family processes, and human development from within a quantitative theoretical tradition. The authors model an interactionist approach, which proposes a dynamic relationship between SES and developmental change over time. Even if you are not interested in the topic have a look at the way the authors structure their argument. The point here is that those working within quantitative traditions are often seen to be atheoretical and too ready to mistake statistical association for explanation. In contrast you can see here that the authors are modelling but that this modelling rests on a deep engagement with theoretical explanations of human development.
