Understanding Attachment Styles — Secure, Anxious, Avoidant
Last reviewed by the Men Women Psychology editorial team.
The evidence
What the research actually shows
Hazan and Shaver (1987) made the foundational move of applying attachment theory to adult romantic love, proposing that the bonds between partners draw on the same system that links children to caregivers. Their early work described three patterns — secure, anxious, and avoidant — that predicted how people experienced and behaved in relationships, and it launched decades of research.
Bartholomew and Horowitz (1991) refined this into a four-category model organized around two dimensions: how positively people view themselves and how positively they view others. This yields secure (comfortable with closeness and autonomy), anxious or preoccupied (craving closeness while fearing rejection), dismissing-avoidant (valuing independence and downplaying intimacy), and fearful-avoidant (wanting closeness yet fearing it). Today researchers often describe these as positions along two continuous dimensions — attachment anxiety and avoidance — rather than rigid boxes.
Mikulincer and Shaver's extensive synthesis (2007) shows how these patterns play out across adult life: securely attached people tend to handle conflict and seek support more constructively, while higher anxiety or avoidance is associated with characteristic struggles. Importantly, this body of work also documents that attachment can change — through new relationships, reflection, and sometimes therapy — supporting the idea of 'earned security.'
The mechanism
Why this happens
Attachment patterns are thought to begin in early relationships, where repeated experiences with caregivers teach a child what to expect from closeness: whether bids for comfort are reliably met, inconsistently met, or discouraged. These expectations form internal working models — rough templates for how relationships go — that can carry into adulthood.
But early experience is not the whole story. Later relationships, significant life events, and ongoing patterns continue to shape attachment. A consistently responsive partner can gradually nudge someone toward security, while painful relationships can move someone the other way. This is why researchers describe attachment as relatively stable but genuinely open to change.
The styles persist partly because they are self-reinforcing. Someone high in anxiety may monitor for signs of rejection and seek reassurance in ways that can strain a relationship; someone high in avoidance may withdraw when intimacy deepens, keeping bonds at a manageable distance. Each pattern tends to recreate the very dynamics it expects, which is part of why awareness can be so useful in interrupting it.
In practice
What this looks like in real life
A person with a more anxious pattern might feel a spike of worry when a partner is slow to reply, seek frequent reassurance, and read distance into ordinary quiet — behaviors that come from a deep desire for closeness paired with a fear of losing it.
Someone with a more avoidant pattern might feel crowded as a relationship gets serious, value self-reliance strongly, and pull back or change the subject when conversations turn emotional — not from lack of care, but from discomfort with depending on others.
A securely attached person tends to express needs directly, offer and accept comfort, and stay relatively steady during conflict, trusting that closeness and a separate sense of self can coexist. Many people are mixtures, leaning one way under stress and another when secure.
Myth vs. evidence
What most people get wrong about this
A common misconception is that an attachment style is a fixed label that permanently defines someone or dooms a relationship. Research suggests styles are influential but changeable, and many people develop greater security over time. Treating a style as an unchangeable identity, or as an excuse, misreads what the science actually shows.
Pop psychology also tends to oversimplify, sorting everyone neatly into one of four boxes and treating 'avoidant' or 'anxious' as character verdicts. In reality, attachment is better understood as positions on continuous dimensions that can vary by relationship and situation, and the labels describe patterns of behavior, not a person's worth.
Why it matters
What this means for relationships
Understanding your own and a partner's patterns can defuse painful cycles. A classic one pairs an anxious partner who pursues closeness with an avoidant partner who withdraws, each amplifying the other's fear. Naming the dynamic, rather than blaming, can help both people respond to the underlying need instead of the surface behavior.
Because security can be earned, consistent responsiveness matters. Partners who reliably show up, offer comfort, and respect each other's autonomy can gradually help one another move toward more secure functioning. This is slow work, but research suggests relationships can be a route toward greater security, not just a stage where old patterns repeat.
Where it varies
The nuance
Attachment styles are tendencies, not fixed types, and they can differ across relationships and shift with experience. Many people do not fit one category cleanly, and stress can pull out patterns that calmer times keep in check. The framework is a useful lens, not a precise diagnosis.
While there are some average differences in how the patterns show up between men and women, attachment style itself is not a gender trait — both sexes span the full range. Janet Hyde's gender similarities hypothesis (2005) supports treating attachment as an individual characteristic that predicts relational behavior far better than gender does.
Questions people ask about this
What are the four attachment styles?
Drawing on Bartholomew and Horowitz's model, they are secure (comfortable with closeness and independence), anxious or preoccupied (craving closeness while fearing rejection), dismissing-avoidant (prizing independence and downplaying intimacy), and fearful-avoidant (wanting closeness yet fearing it). Researchers increasingly describe these as positions along attachment anxiety and avoidance dimensions.
Where do attachment styles come from?
Research suggests they begin in early relationships, where repeated experiences with caregivers shape expectations about closeness. These form internal working models that can carry into adulthood. But later relationships and life events continue to shape attachment, so early experience is influential without being the whole story.
Can your attachment style change?
Yes. Research describes attachment as relatively stable but genuinely open to change. Through consistently responsive relationships, reflection, and sometimes therapy, many people move toward greater security — often called earned security. A style is a pattern that can evolve, not a permanent verdict.
Is one attachment style better than the others?
Security is generally associated with smoother conflict, better support-seeking, and higher relationship satisfaction, so it tends to be the most adaptive. But anxious and avoidant patterns are common and understandable adaptations, not character flaws. Awareness of any pattern can help, and people with insecure styles can build healthy relationships.
Do men and women have different attachment styles?
Attachment style is not a gender trait — both sexes span the full range of patterns. There are some average differences in how patterns show up, but Janet Hyde's research suggests attachment functions as an individual characteristic that predicts relational behavior far better than gender does.
What happens when an anxious and avoidant person date?
This pairing can create a painful cycle: the anxious partner pursues closeness while the avoidant partner withdraws, each amplifying the other's fear. Naming the dynamic without blame, and learning to respond to the underlying needs, can help. Such relationships can work, especially as both partners move toward more security.
