Household income differentiates quantity and quality of shared spousal time.

Shared time is a centrally important component of relationship maintenance, and over the past few decades, couples have reported spending increasingly more time together. However, over this same time period divorce rates have risen much higher for lower income couples compared to higher income couples. One theorized explanation for the disparity in divorce rates between lower and higher income couples is a difference across the socioeconomic strata in the quantity and quality of time couples spend together.

How diverse are the samples used to study intimate relationships? A systematic review.

The social and behavioral sciences have long suffered from a lack of diversity in the samples used to study a broad array of phenomena. In an attempt to move toward a more contextually-informed approach, multiple subfields have undertaken meta-science studies of the diversity and inclusion of underrepresented groups in their body of literature. The current study is a systematic review of the field of relationship science aimed at examining the state of diversity and inclusion in this field.
