Childhood care shapes adult trust, but attachment patterns can still change

Research links early warmth, rejection and overprotection with how adults trust and relate to partners, but later experiences and therapy can help reshape attachment patterns.

Childhood experience can shape how adults trust, avoid, or depend on partners, but the pattern is not fixed for life. Psychologist Andreea Ionescu, author of “Harta invizibilă a atașamentului”, says research on attachment has long linked early caregiving to the way people later approach close relationships, with adult attachment styles often described through a person’s view of themselves and of others. In this framework, attachment is usually understood as a balance between dependence and avoidance, and the quality of emotional care in childhood remains one of the clearest predictors of security in later relationships.

A study by Perris and Andersson, cited by Ionescu, found that emotional warmth in childhood was strongly associated with secure attachment in adulthood, while rejecting or overprotective parenting patterns were linked to less secure attachment. The same research also suggested that these connections held across different relationship settings, not only romantic partnerships. It further pointed to some sex-based differences: men appeared more strongly affected by overprotection, while women showed a stronger link between parental rejection and insecure attachment. Similar findings have been reported elsewhere. A comparative study in the journal attached to PubMed found that recalled parental care and low overprotection were associated with secure adult attachment across Spanish, Italian and Japanese samples, suggesting that the family environment matters even when culture differs.

Other research adds that these early patterns can show up in how people trust a partner. A recent PubMed study found that parental divorce, relationship breakdowns and anxious or avoidant attachment were all linked with lower trust in adult romantic relationships, while positive beliefs about relationships were associated with higher trust. Another longitudinal study of heterosexual couples found that attachment style and gender together shaped relationship stability over time, showing that avoidant men and anxious women could still form durable partnerships, depending on the wider relationship dynamic. Taken together, the findings suggest that attachment is not simply about whether someone is secure or insecure, but about how that style interacts with experience, expectations and behaviour over time.

There is, however, room for change. Ionescu notes that when life events do not match a person’s expectations, or when they begin to make sense of earlier experiences more clearly, the internal models that support adult attachment can shift. That idea is supported by research on life events, social context and resilience, which found that adult attachment is not completely fixed. A twin study published on PubMed also indicated that adult attachment is shaped by both inherited and environmental influences, with non-shared experience accounting for a substantial share of variation. In practical terms, that means early family relationships matter greatly, but they do not write the final script: therapeutic work and later supportive relationships can help some people move towards a more secure style.
