Three methodological approaches to studying singlehood

As the number of single (unpartnered) individuals continues to rise, researchers across various disciplines have started to pay more attention to single individuals' lives. Yet, compared to the accumulated knowledge about experiences within romantic relationships, there is far less known about various experiences within singlehood. For singlehood research to grow in both quantity and quality, it is essential that research findings are critically evaluated both in terms of robustness of the evidence and validity of the inferences. In this paper, we review three broad approaches researchers have taken to understand singlehood that centered on (a) between-group status (i.e., single vs. in a relationship) differences, (b) within-person status differences, and (c) within-group variability among singles. With a focus on well-being as an outcome, we illustrate how each approach provides unique insights into singlehood and what caveats there are in interpreting results derived from each approach. Finally, we identify questions or methods that have not been extensively explored within each approach and offer suggestions for future research directions.
