Depression stands as one of the most prevalent mental health disorders in the United States, affecting over 21 million adults aged 18 and older in 2021 alone (National Institutes of Mental Health [NIMH], 2021). This disorder presents differently across genders, with women reporting nearly double the incidence compared to men (NIMH, 2021), and a higher propensity to seek treatment, especially as they age (NIMH, 2016b). Yet, historical clinical research has often neglected the female perspective, leaving a gap in effective mental health interventions for women (National Institutes of Health [NIH], 2001; Bentley, 2005).
It is imperative to address these disparities, particularly considering that women place significant emphasis on relational contexts for their growth and development (Hurst, Leberman, & Edwards, 2017). Women’s relational distress, frequently associated with transitions such as the end of a marriage or cohabitation (Sassler & Lichter, 2020), is a common precipitant of seeking mental health services (Federal Partners Committee on Women and Trauma, 2013). Therefore, a nuanced understanding of relational dynamics is essential for effective diagnosis and treatment. There is an emerging body of research that does explore this nuance. For example, recent research has examined relationship confidence, defined as the belief that both partners possess the skills to manage conflict and sustain their partnership (Johnson et al., 2020). In their study of unmarried young adults, the authors find relationship confidence was generally stable but exhibited notable gender differences. Women began with higher confidence, which declined over time, while men’s confidence increased. Factors such as longer partnerships, cohabitation, and lower avoidant attachment were linked to greater confidence in their study, especially among those who married during the study.
Similarly, Bae and Kogan (2020) explored how adverse life contexts shape African American men’s romantic relationship trajectories. Their study identified three distinct trajectories—Normative, Uncertain, and Conflictual—with early adversity, socioeconomic instability, and community disadvantage significantly contributing to Uncertain and Conflictual patterns. Taken together, this underscores the nuance and complexity of relational dynamics and their implications for mother’s mental well-being, but additional work is needed to disentangle the link between relationship histories and well-being.
Current documentation tools such as genograms, timelines, and ecomaps, while providing detailed relational histories (Marquis & Holden, 2008), suffer from a lack of standardization, rendering cross-patient comparison difficult (Nakash et al., 2008). To this end, our paper proposes the development of standardized relational instability survey items to supplement traditional intake methods, thereby offering a more objective and comparable means of assessing relational factors.
By integrating these refined tools into initial assessments, practitioners can more accurately identify risks for depression based on relational history, contributing to more effective case conceptualization and treatment planning (Meyer & Melchert, 2011). This approach also responds to the critique of previous practices being marriage-centric, heteronormative, and inadvertently condescending towards women, by promoting inclusivity and appreciating the diversity of human relationships (Federal Partners Committee on Women and Trauma, 2013).
To this end, the central objective of our study was to identify the most effective family complexity measures for predicting depression among middle-aged women, enhancing diagnostic assessments for practitioners. Our work is groundbreaking in its integration of academic and professional expertise to propel strength-based, empirically-supported practices. We leverage the National Longitudinal Survey of Youth 1979 for its longitudinal data on women's family experiences from adolescence to midlife, informing the development of our family instability measures. By reducing bias by controlling for covariates altering key family practices, we thoroughly test the efficacy of each measure in understanding midlife depression.
The study was executed in five methodical steps. Initially, we analyzed 24 waves of the NSLY79 to craft three innovative measures of family change, benchmarking them against existing scholarly metrics. We then scrutinized the relationship between these family instability measures and major depression, using NLSY sampling weights to ensure accuracy reflective of complex sample designs. This helped us confirm the consistency of our measures with previous findings. In our third step, we considered a breadth of contextual factors potentially impacting the health-instability nexus, informed by practitioner input and literature suggesting that family diversity encompasses both structure and socioeconomic stratification, including race, education, and poverty. Additionally, recognizing the impact of parental depression on children, we factored in childbearing.
We generate four hypotheses. First, people in formal, stable relationships (e.g., marriage) are hypothesized to have lower odds of experiencing major depressive symptoms compared to single individuals. Within relationship types, the least complex relationships (fewest transitions such as separation or divorce) are associated with the lowest odds of depression. Second, histories create a continuum of depressive symptomology risk, with stably married individuals at one end (lowest risk) and those with multiple divorces at the other (highest risk). Within this continuum, currently partnered individuals (married, remarried, cohabiting) have lower odds of major depressive symptoms than single individuals (always single, single post-cohabitation, widowed, separated, divorced). Additional divorces increase the odds of major depressive symptoms, indicating a correlation between relationship transitions and depressive symptomology. Third, there is a direct correlation between the number of relationship transitions a woman has experienced and the likelihood of experiencing major depressive symptoms. The more transitions, such as separations or divorces, the higher the odds of depressive symptoms. The final hypothesis integrates previous theories, proposing that the odds of depressive symptoms are distributed across three hierarchical groupings: (a) partnered vs. single, with partnered individuals having lower odds, (b) within each group, most-formal/least-complex relationships are associated with the lowest odds, and (c) within each relationship type, a higher number of transitions correlates with higher odds of depressive symptoms.
Women’s Mental Health in Midlife
Midlife often brings health declines, occupational stagnation, and stress, which can heighten mortality awareness and regret over unachieved goals, potentially exacerbating existing mental health issues (Sievert et al., 2018). Additionally, the caregiver responsibilities assumed by individuals at this life stage can lead to significant family and generational stress when compounded by mental health crises (Guzzob& Hayford, 2020; Infurna et al., 2020).
Middle-aged women are particularly susceptible to depression, with rates nearly double those of men (NIMH, 2021), influenced by societal norms and an accumulation of stressors such as poverty and caregiving demands (Kessler et al., 1993; Afifi, 2007; Cawthorne, 2008).
Family Change and Instability
American family structures have evolved, with middle-aged women now more likely to navigate complex relationship trajectories than previous generations (Smock & Schwartz, 2020). Women's greater likelihood to initiate divorce and the associated mental health impacts call for a deeper understanding of how family dynamics influence depression (Raley & Sweeney, 2020).
Research measures family instability through current relationship status, cumulative transitions, and relationship trajectories. Each metric contributes differently to our understanding of women's depression in midlife, informed by foundational theories such as the Life Course Perspective, Pearlin’s Stress Process Model, and Family System’s Boundary Ambiguity Theory (Elder, 1985; Pearlin & Johnson, 1977; Pearlin et al., 1981; Boss & Greenberg, 1984).
These theories suggest that relationships significantly influence mental health through mechanisms like role strain and boundary ambiguity, which may intensify with transitions such as divorce and remarriage (Brown & Manning, 2009; Carroll et al., 2007; Pasley, 1987).
Relationship Status and Instability
A woman's current relationship status, from single to married, impacts her mental health, with formal relationships potentially offering stability and informal or complex relationships possibly increasing stress and depression risk (Brown, Manning, & Wu, 2022; Raley & Sweeney, 2020). The end of relationships, whether through divorce, widowhood, or separation, also correlates with mental health declines, though these effects can vary over time and by individual circumstances (Raley & Sweeney, 2020).
Cumulative Transitions and Relationship Sequences
Beyond current status, the number and sequence of relationship transitions across a woman's life play a role in mental health outcomes. Cumulative transitions often indicate increased mental health risks (Umberson & Thomeer, 2020), supported by research on the stress and confusion arising from complex family dynamics (Meadows, McLanahan, & Brooks-Gunn, 2008; Wu & Hart, 2002; Amato, 2010).
