Genetic and environmental factors underlying the associations between attachment styles and mental and physical health
30), but little-to-no overlap among the environmental factors that contribute to attachment anxiety and physical health. Thus, the associations between attachment anxiety and physical health outcomes appear to be primarily attributable to a common or shared genetic liability. Attachment avoidance shared weak or near-zero associations with indicators of physical health. (PsycInfo Database Record (c) 2026 APA, all rights reserved)
A prospective longitudinal study of the associations between childhood and adolescent interpersonal experiences and adult attachment orientations
Attachment theory (Bowlby, 1973, 1980, 1969/1982) suggests that early interpersonal experiences lay the foundation for the ways people think, feel, and behave in close relationships throughout life. The present study examined this fundamental assumption, analyzing longitudinal data collected from 705 participants and their families over 3 decades, from the time participants were infants until they were approximately 30 years old ( M age = 28.6, S…
Coordination of parent and adolescent attachment across time
Adolescence is a period of rapid social changes that may have important implications for the ways adolescents think, feel, and behave in their close relationships. According to family systems theory, adolescents' attachment-related changes have the potential to spread throughout their family system, leading to coordinated changes in parents' and adolescents' attachment styles over time. The present study analyzed data from 205 adolescents ( M age…
Life events sometimes alter the trajectory of personality development
OBJECTIVE: Personality changes across the life span. Life events, such as marriage, becoming a parent, and retirement, have been proposed as facilitating personality growth via the adoption of novel social roles. However, empirical evidence linking life events with personality development is sparse. Most studies have relied on few assessments separated by long time intervals and have focused on a single life event. In contrast, the content of lif…
Systematic review of queer and minority identities in romantic relationships research
Romantic relationships are key to our health, yet recent reviews of relationships research show that sexual and/or gender diverse people and other traditionally under-represented groups are frequently excluded. Articles published from 2016 to 2020 in four relationships journals were reviewed to address the overall representation of sexual and gender minority (SGM) respondents (k = 891), and discuss the specific social identities included in U.S. …
Person-situation interactions as predictors of variations in attachment
Existing work on the contribution of life events and person characteristics to changes in attachment has mostly overlooked interactions between events and characteristics. Using 15 common events and ten personality characteristics in a multi-wave longitudinal study of 6,566 people, we examined whether person characteristics moderate the impact of life events on change in attachment. Although we found more interactions than were expected by chance…
Genetic and environmental contributions to adult attachment styles
Attachment theory, as originally outlined by Bowlby (1973, 1980, 1969/1982), suggests that the ways people think, feel, and behave in close relationships are shaped by the dynamic interplay between their genes and their social environment. Research on adult attachment, however, has largely focused on the latter, providing only a partial picture of how attachment styles emerge and develop throughout life. The present research leveraged data from t…
Testing the canalization hypothesis of attachment theory
5.31; median test-retest interval = 35 days). We modeled participants' within-person fluctuations in partner-specific security as a function of their romantic relationship length. Additionally, we examined whether attachment-related events (e.g., conflict with one's partner) predict greater within-person fluctuations in security among people involved in newer versus more established romantic relationships. Our results suggest that people in newer…
Dismissing Attachment and Global and Daily Indicators of Subjective Well-Being
The present research examined whether a dismissing attachment style (i.e., being high in attachment avoidance and low in attachment anxiety) is a risk factor for low subjective well-being (SWB). Specifically, we examined the associations between dismissing attachment and two indicators of SWB: global life satisfaction and daily affect. Self-reports of attachment and overall life satisfaction were collected from 257 adults at an initial lab sessio…
The roles of parental and partner attachment working models in romantic relationships
Attachment theory suggests that romantic relationship dynamics are not only shaped by how people relate to their partners but also by the bonds they share with other important people in their lives. The present study investigated how parental and partner attachment representations work together to predict romantic relationship functioning. In addition, we examined how the associations between these working models and relationship functioning migh…
Changes in global and relationship-specific attachment working models
Attachment theorists suggest that people construct a number of distinct working models throughout life. People develop global working models, which reflect their expectations and beliefs concerning relationships in general, as well as relationship-specific working models of close others-their mothers, fathers, romantic partners, and friends. The present research investigated the interplay of these different working models over time. We analyzed l…
