When you take an attachment style test, you're typically filling in a version of the Experiences in Close Relationships scale — the ECR. It's not a quiz someone invented for the internet. It's the dominant measurement instrument in adult attachment research, used in thousands of peer-reviewed studies since the late 1990s. Understanding how it works gives you a more honest read on what your score actually means.
Where the ECR came from
The scale was developed by Kelly Brennan, Catherine Clark, and Phillip Shaver and published in 1998. Brennan and her colleagues took a different approach from earlier attachment measures: rather than starting with clinical theory and building items to match, they began with the actual language people use to describe their feelings in romantic relationships.
They collected 323 existing questionnaire items from every available self-report attachment measure at the time and ran them through a large-scale factor analysis — a statistical method for finding patterns in how items cluster together. Two clean dimensions kept emerging, regardless of which original items they used.
Those two dimensions became the axes of the ECR: attachment anxiety and attachment avoidance. This was a significant finding. Researchers had been debating whether adult attachment should be categorized into types or measured on continuous dimensions, and the data came down decisively on the side of dimensions. Your attachment style isn't a box you belong to — it's a position on two intersecting spectrums.
The two dimensions
Attachment anxiety measures how much you worry about whether your partner values you, whether they'll leave, and whether you're "enough" in the relationship. High anxiety on this scale reflects the fear of abandonment, hypervigilance to rejection cues, and the need for frequent reassurance that you're loved and secure. People high on anxiety tend to have racing thoughts during relationship uncertainty and struggle to self-soothe when their partner isn't available.
Attachment avoidance measures how uncomfortable you feel with closeness, dependence, and emotional vulnerability in relationships. High avoidance reflects a tendency to withdraw when things get emotionally intense, discomfort with others depending on you, and a preference for self-reliance over intimacy. People high on avoidance often value independence highly and experience closeness as threatening or suffocating — not because they don't care, but because closeness triggers an automatic defensive response.
The four attachment style categories you've probably heard of — secure, anxious, avoidant, and fearful-avoidant — are simply quadrants formed by these two axes:
- Secure: low anxiety, low avoidance
- Anxious (also called preoccupied): high anxiety, low avoidance
- Dismissing-avoidant: low anxiety, high avoidance
- Fearful-avoidant (also called disorganized): high anxiety, high avoidance
For a closer look at how each of these plays out in behavior and relationships, see our guides to avoidant attachment style, anxious attachment triggers, and fearful-avoidant attachment.
The ECR-R: a refinement
In 2000, Chris Fraley, Niall Waller, and Kelly Brennan published an updated version: the ECR-R (Revised). The revision used item response theory — a more sophisticated psychometric approach — to select items that provide maximum measurement precision across the full range of each dimension, rather than just at the extremes.
The ECR-R is now considered the gold standard. It uses 36 items: 18 measuring anxiety and 18 measuring avoidance, each rated on a 7-point scale from "Disagree strongly" to "Agree strongly." Your scores on each subscale are averaged to produce a number between 1 and 7. Higher scores mean more of that dimension; lower scores mean less.
The measure has excellent psychometric properties: high internal consistency, good test-retest reliability over short periods (it's measuring a relatively stable trait), and strong evidence of validity — the scores predict relationship outcomes in expected ways.
What the ECR measures and what it doesn't
The ECR measures your default relational strategies — the patterns you tend toward when emotionally close to someone. It's specifically designed for romantic attachment relationships, not friendships or family relationships (though parallel measures exist for those).
What it doesn't measure: the quality of any specific relationship, whether your attachment style is "good" or "bad," or whether you have diagnosable anxiety or avoidance disorders. A high anxiety score means you tend to worry in close relationships — not that you have generalized anxiety disorder.
It also doesn't measure your conscious preferences for how you'd like to behave. Some people who score high on avoidance genuinely wish they could be closer to partners but find that closeness triggers an involuntary protective response. The ECR captures these implicit, automatic patterns, not just stated values.
How stable is your attachment style?
The ECR scores are fairly stable over periods of months to years, supporting the idea that attachment patterns are real and enduring features of personality. But "stable" doesn't mean "fixed." Several factors are associated with attachment style change over time:
- Long-term secure relationships. Sustained experience with a consistently responsive, non-rejecting partner gradually updates the internal working model that drives attachment behavior.
- Therapy. Attachment-focused therapy — including approaches like emotionally focused therapy (EFT) and schema therapy — creates conditions similar to a secure relationship through the therapeutic relationship itself.
- Major life events. Significant loss, trauma, or conversely, profound safety, can shift scores.
Research on this is reviewed in depth in our piece on whether attachment styles can change. The short version: movement is possible, but it typically takes sustained experience over time, not just insight.
The ECR in research
The scale has been used to study an enormous range of questions: how attachment predicts relationship satisfaction, how it shapes conflict behavior, how it relates to mental health outcomes, how it influences parenting behavior, and how it changes across the lifespan. Some findings that hold consistently across studies:
- High avoidance predicts less disclosure and emotional expressiveness in relationships.
- High anxiety predicts more relationship conflict and more intense negative reactions to perceived rejection.
- Secure attachment (low on both dimensions) consistently predicts higher relationship satisfaction and better communication.
- Both high anxiety and high avoidance are associated with greater loneliness, though through different mechanisms — anxious individuals tend to feel disconnected even when in relationships; avoidant individuals tend to feel disconnected by choice until the solitude itself becomes painful.
The difference between research scales and popular tests
The full ECR-R — 36 items, carefully validated — is what researchers use. Most online tests, including this one, use shortened or adapted versions because the full scale is long for general use. Shorter versions sacrifice some precision but retain the core measurement logic.
What this means practically: an online attachment screener gives you a reasonable, directionally accurate picture of where you land on these two dimensions. It won't give you a clinically precise score or tell you whether attachment issues are contributing to specific relationship problems you're experiencing. For that, a qualified therapist who works with attachment — particularly one trained in EFT or emotionally focused individual therapy — can administer validated measures and interpret them in the context of your actual relationship history. See therapy for attachment issues for guidance on what that might look like.
What to do with your score
Knowing you're high on anxiety or avoidance is the beginning of the work, not the end of it. The value isn't in the label — it's in the behavioral patterns the label points toward.
If you're high on anxiety: the productive question is what specific situations tend to trigger the spike — what does your nervous system read as a sign of abandonment, and what does reassurance-seeking actually provide (and cost) you? Our piece on anxious attachment triggers breaks this down in practical terms.
If you're high on avoidance: the useful question is what specifically you're protecting against when closeness triggers withdrawal, and whether those protective strategies are still serving you or just keeping you isolated. The piece on avoidant attachment style covers this in detail.
If you're fearful-avoidant — high on both — the experience is uniquely difficult: wanting closeness and simultaneously fearing it. This pattern most often has its roots in early experiences where caregivers were both a source of comfort and a source of fear, and it tends to benefit most from professional support. See the fearful-avoidant guide for more.
And if you're secure — or close to it — that's worth recognizing. Secure attachment didn't emerge from nowhere; it was built from experience, and the same is true of insecure patterns.
