Uncovering measurement bias: Differential item functioning by income in the Couples Satisfaction Index.

Relationship satisfaction is among the most popular constructs in family science. As the study of families and romantic couples continues to include more diverse samples, it is imperative to ensure the measures scholars use do not significantly vary in psychometric quality across groups. The goal of this study was to examine the psychometric utility of the four-item Couples Satisfaction Index (CSI-4; Funk & Rogge, 2007) for individuals across the income spectrum. This study uses data from the National Couples' Health and Time Study, which sampled married and cohabiting adults in the United States from late 2020 to early 2021. Differential item functioning in the CSI-4 was assessed based on income (N = 3,497) using item response theory. For individuals experiencing lower incomes, the CSI-4 demonstrated differential functioning compared to their more affluent peers, with a bias against individuals experiencing lower incomes equating to average scores 1.38 units lower than higher income participants on the CSI-4 despite having the same true levels of relationship satisfaction. Differential item functioning was less pronounced when comparing item performance of lower- and middle-income participants, equating to lower income participants scoring .21 units lower than middle-income individuals despite having the same true levels of relationship satisfaction. While advancing diversity in family science, researchers should employ psychometric methods to understand how measures perform across groups, which will help prevent the misinterpretation of statistical bias as real group differences.

The role of emotional dysregulation in the association between family-of-origin conflict and romantic relationship maintenance.

Family-of-origin systems are consequential for the emotional well-being of offspring. These influences are likely to last into adulthood, affecting adult children's romantic relationships. The mechanisms by which family-of-origin environments influence adult romantic relationships are not fully understood. In a sample of 118 different-sex couples, we tested the effects of negative family-of-origin conflict on adult offspring's provision of relationship maintenance to their romantic partner using structural equation modeling. We evaluated emotional dysregulation as a mediator of this effect, using two measures of emotional dysregulation. Results from structural models demonstrated a negative effect of family-of-origin conflict on the provision of relationship maintenance via higher levels of emotional dysregulation. Our results highlight emotional self-regulation as a valuable intervention point for couple therapists.

The effects of discrimination and psychological distress on U.S. Latino/a young adults' relational uncertainty and relationship instability.

OBJECTIVES: Racial/ethnic discrimination is a common and salient stressor for many individuals. Although discrimination can impair personal and relational well-being, little is known about its influences on the process of considering dissolution (i.e., relationship instability). In two studies of Latino/a young adults, we examined associations among discrimination, psychological distress, relational uncertainty, and relationship instability. METHOD: Study 1 assessed self-reports of 475 participants aged 18-29 (60.2% female, Mage = 24.8, SD = 3.22). Study 2 examined self-reports of 462 participants aged 18-29 (40.9% female, Mage = 25.9, SD = 2.72). Structural equation models evaluated direct and indirect associations among study variables. RESULTS: Discrimination was associated with relationship instability, both directly and indirectly via its associations with psychological distress and, in Study 1, relational uncertainty. CONCLUSIONS: Overall results suggest that racial/ethnic discrimination is associated with romantic relationship instability through its associations with psychological distress and uncertainty about the future of a relationship. Prior research demonstrates the resilience of Latino/a communities, and our findings reinforce the need for policies and clinical resources that reduce discrimination and support mental health and relationships.

Prior On-Off Relationship Instability and Distress in the Separation and Divorce Transition.

Divorce is considered distressing for many individuals (Sbarra et al., Current Directions in Psychological Science, 2015, 24, 109); however, individuals in poor-quality relationships may experience certain benefits of leaving an unstable union (Amato & Hohmann-Marriott, Journal of Marriage and Family, 2007, 69, 621). On-off relationship cycling, or the breakup and reconciliation of a relationship, is a salient indicator of poor relationship quality and a common form of relationship instability (Dailey et al., Personal Relationships, 2009, 16, 23) that is associated with distress (Monk et al., Family Relations, 2018, 67, 523). In line with divorce-stress-adjustment and relational turbulence theory perspectives, we hypothesized that those whose relationships were characterized by on-off instability would experience less distress during the separation and divorce process. Given gender inequality in marriage (e.g., Dempsey, Journal of Sociology, 2002, 38, 91; Monin & Clark, Sex Roles, 2011, 65, 320), we also hypothesized that this association would be more pronounced for women. Using data from 98 divorced or separating couples, we found that relationship cycling prior to the separation and divorce process was associated with fewer distress symptoms for women. Conversely, a history of relationship cycling was associated with more distress symptoms for men. Our study provides support and extends prior investigations illustrating that, for some, those in unions characterized by more turmoil, may experience relief following a termination.

El divorcio se considera angustiante para muchas personas (Sbarra et al., 2015); sin embargo, las personas que tienen relaciones de mala calidad pueden percibir ciertos beneficios al romper una unión inestable (Amato & Hohmann-Marriott, 2007). El ciclo intermitente de las relaciones, o la separación y la reconciliación de una relación, es un indicador prominente de la mala calidad de la relación y una forma común de inestabilidad relacional (Dailey et al., 2009) que está asociada con el distrés (Monk et al., 2018). En consonancia con las perspectivas de adaptación al estrés por el divorcio y de la teoría del estrés relacional, planteamos la hipótesis de que aquellas personas cuyas relaciones se caracterizaban por la inestabilidad intermitente sufrirían menos distrés durante la separación y el proceso de divorcio. Dada la desigualdad de género en el matrimonio (p. ej.: Dempsey, 2002; Monin & Clark, 2011) también planteamos la hipótesis de que esta asociación sería más marcada para las mujeres. Utilizando datos de 98 parejas divorciadas o que se estaban separando, descubrimos que el ciclo relacional anterior a la separación y al proceso de divorcio estuvo asociado con menos síntomas de distrés en las mujeres. Contrariamente, un historial de ciclo relacional se asoció con más síntomas de distrés en los hombres. Nuestro estudio ofrece respaldo y amplía investigaciones previas demostrando que algunas personas que están en uniones caracterizadas por más confusión pueden sentir alivio después de una separación.
