Attachment Styles, Neuroticism, and Relationship Health

When people think about public health, romantic relationships rarely come to mind. Yet relationship quality is deeply connected to health behaviors, stress regulation, and safety, making romantic relationships an important—but often overlooked—public health issue. To understand how romantic relationships influence health, it helps to examine how people form and maintain emotional bonds that shape relationship dynamics.

Attachment theory provides a framework for understanding how early caregiving experiences shape emotional openness and emotional regulation in adulthood. Attachment styles are typically categorized as secure or insecure (i.e., anxious, avoidant, or disorganized). Secure attachment reflects comfort with closeness and trust, while insecure attachment includes anxious patterns or fear, emotional reactivity, and avoidant patterns of discomfort with intimacy and withdrawal.

Insecure attachment styles are associated with decreased relationship satisfaction and stability, often due to conflict, miscommunication, and difficulties with emotional regulation. People with anxious attachment may interpret neutral behaviors, like a partner needing space or being busy, as signs of abandonment. Those with avoidant attachment often feel uncomfortable with vulnerability and may change the subject when emotional topics come up. Insecure attachment can lead to chronic relationship stress, which slowly deteriorates health. Health conditions associated with chronic relationship stress include depression, anxiety, and poor immune health.

Personality traits can further shape these dynamics. One key personality trait influencing attachment styles is neuroticism—a tendency toward emotional sensitivity and negative emotions that exists on a spectrum. At high levels, people may have strong reactions to minor stressors and face difficulty regulating emotions, which can linger for hours or days. For example, a minor mistake at work leads to disproportionate guilt, self-blame, and difficulty concentrating for hours. The spectrum of neuroticism ranges from everyday worry to more intense, impulsive, or sensitive emotional reactions. Everyone has some degree of neuroticism, with high levels associated with relationship strain and psychological distress.

To understand the intersection of neuroticism and attachment style in relationships, Jeffrey B. Jackson and colleagues analyzed data from more than 1,250 heterosexual couples, examining how anxious and avoidant attachment styles relate to neuroticism and relationship quality, including how one partner’s traits can affect both partners’ relationship satisfaction.

Both insecure attachment styles and high levels of neuroticism were correlated to less satisfying relationships with the reverse observed for securely attached individuals and those with lower neuroticism. Stable, satisfying romantic relationships were linked to better mental and physical health. The findings also echoed prior research highlighting the relationship between chronic relationship distress and depression, anxiety, and long-term instability.

Insecure attachment styles were associated with neuroticism, whereas secure attachment was linked to lower neuroticism. While attachment style was strongly associated with individuals’ own neuroticism, it showed no significant influence on their partners’ neuroticism. Individuals with anxious or avoidant attachment were more likely to exhibit higher levels of neuroticism, which was associated with lower relationship satisfaction and stability for both men and women.

Gender differences also surfaced. Women’s neuroticism was associated with reduced satisfaction among their male partners, whereas the reverse pattern was not observed. Additionally, women’s anxious and avoidant attachment styles were indirectly associated with decreased male partners’ satisfaction. These findings likely reflect broader gendered expectations regarding responsibilities of emotional labor. Women are often socialized to manage or respond to emotional needs within relationships, making their emotional expressions more visible in relationship dynamics. This pattern underscores how social expectations shape interpersonal processes within relationships, rather than attributing responsibility to women’s traits. A key limitation is that the study did not examine disorganized attachment, which limits understanding of more complex attachment patterns.

With more than half of U.S. adults estimated to have insecure attachment and increasing rates of those with neuroticism in the past 5 years, early identification of emotional and relational risk factors is essential. Integrating screening and referral to evidence-based, emotionally focused therapies with primary care and community mental health settings can strengthen relationship stability and reduce downstream health risks.
