Attachment style tests: what they measure, and what they cannot

What are attachment styles?

Attachment theory began with observations of infants and the people who cared for them, and moved into adult life when Hazan and Shaver proposed that romantic love can be understood as an attachment process, running on the same small set of patterns (Hazan & Shaver, 1987). They described three: secure, anxious (sometimes called anxious-ambivalent) and avoidant. In their two questionnaire studies the three styles turned up in adulthood at roughly the prevalences found in infancy.

In ordinary language: secure describes someone comfortable being close and comfortable being apart, who does not spend much energy checking whether the other person is still there. Anxious describes someone who wants closeness, watches for signs of withdrawal, and feels a gap keenly. Avoidant describes someone who values self-reliance and makes space when a relationship intensifies.

What is being described is narrower than it sounds. Attachment is about what you do when a bond feels uncertain: when a message goes unanswered, when someone asks for more than you were ready to give. It is not a summary of your character, and two people with the same label can be unalike in every other way.

Is attachment three styles, or two scales?

Two scales. Fraley, Waller and Brennan applied item response theory to the main self-report adult attachment questionnaires and found the responses organised by two continuous dimensions rather than by membership of a category: attachment-related anxiety and attachment-related avoidance (Fraley et al., 2000). The same analysis showed that the scales in common use at the time could be improved, and that summing their items can distort conclusions about how stable attachment is.

Attachment anxiety is how much you worry about being valued and about being left, and how strongly you react to signs of distance. Attachment avoidance is how uncomfortable you are with depending on someone and with being depended on. The two move separately, and most people sit in the middle of each rather than at an extreme.

The four labels that circulate online are corners of that two-dimensional space: a fair way to summarise a position and a poor way to measure one. Cutting two scales into four boxes means two people a single point apart receive opposite descriptions.

How does attachment relate to the Big Five?

Closely in one place and loosely elsewhere. Noftle and Shaver measured attachment dimensions and the Big Five in the same samples and found the associations between them consistent and theoretically meaningful, without either set of measures making the other redundant (Noftle & Shaver, 2006). The overlap is easiest to see between attachment anxiety and the reactive end of the dimension Wellington reports as Emotional Stability, once you look at the items. Both ask about worry, about how quickly distress arrives and how long it stays.

Attachment avoidance reads differently. Discomfort with depending on other people shows up partly as less warmth and trust, which is the lower end of Agreeableness, and partly as less pull toward company, which is the lower end of Extraversion, without being the same thing as either.

So an attachment measure relates to personality without restating it. If you know your Big Five profile, attachment scores still add something about the situations where a bond is in question. The reverse is not true: a style label says little about how organised or how curious you are.

Which predicts relationship quality better, attachment or personality?

Attachment, by a modest margin. In the same study, the two attachment dimensions predicted relationship quality better than the Big Five traits did, and continued to predict it after the Big Five had been taken into account (Noftle & Shaver, 2006).

The Big Five result points the same way on the trait that matters most. Across studies of couples, the clearest link with a partner's satisfaction is lower Neuroticism, with smaller links for Agreeableness, Conscientiousness and Extraversion, and no reliable link for Openness to Experience (Malouff et al., 2010). Emotional reactivity is doing much of the work in both literatures, which is why attachment anxiety and Neuroticism keep landing in the same place.

What does a good attachment test look like?

The difference between a serious measure and a four-box quiz is visible before you see the result. A good measure reports two numbers, one for anxiety and one for avoidance, and lets you sit anywhere on each. It asks enough statements per dimension to be stable, because reliability rises with the number of items and very abbreviated measures understate how much a disposition matters (Credé et al., 2012). It asks about a pattern across close relationships rather than the last fortnight, and says where its comparison sample came from.

A four-box quiz usually does the opposite. Twelve questions produce one label, and the description that follows fits a wide range of people. That is the real difficulty. Forer gave a class the same personality sketch and each student rated it as a close description of themselves (Forer, 1949). A result that feels accurate has not, on that evidence alone, measured anything. The test is whether you could have disagreed with it.

What can an attachment result tell you, and what can it not?

Worth taking seriously:

• Where you sit on two dimensions that have held up under measurement scrutiny (Fraley et al., 2000)
• Which situations tend to set you off: distance, closeness, or both in turn
• A reason to look at emotional reactivity and recovery, where much of the effect on relationships sits (Malouff et al., 2010)

Worth resisting:

• Treating a label as a fixed kind of person, when the scores beneath it are continuous
• Reading a score as a verdict on a particular relationship, since the effects are modest averages
• Treating an insecure result as a condition to be treated; it describes a pattern

How does Wellington measure this?

Wellington is a science-based personality assessment from Therabot Labs LLC. It measures personality as continuous traits, built on the Big Five and HEXACO models, and writes the results back as a personal report rather than a type.

Wellington does not report an attachment style, because the honest version of that measurement is two scales from a dedicated questionnaire. What it covers is the territory the two dimensions overlap with. The free Snapshot is 60 questions and about 7 minutes, and reports six broad dimensions: Extraversion, Agreeableness, Conscientiousness, Emotional Stability, Openness to Experience, Honesty-Humility. Two are directly relevant: Emotional Stability, which carries how quickly feeling arrives and how long it takes to settle, and Agreeableness, which carries trust, warmth and cooperation. The first ten questions are answered before anything is asked; after question ten you sign in with an email so your answers are saved and your results can be shown. There is no card.

The Wellington Membership, $4.99 a month, adds the Portrait, 336 questions in 4 chapters, to reach 90 traits, including every Big Five facet: Trust, Sympathy, Trait Warmth and Tender-Mindedness beneath Agreeableness, and Trait Calmness, Trait Equanimity and Trait Imperturbability beneath Emotional Stability, which a single domain score flattens into one number.

It also adds a short weekly module toward all 255 traits across eight domains. Relationship and trust traits arrive there: Trusting Disposition, Belonging, Group Engagement, Civic Connection and Romantic Engagement, along with Romance and Partnership Activity in the lifestyle domain. Every trait is the average of several statements on a five-point accuracy scale, placed against a reference sample as a percentile and reported in one of three bands, Quiet below the 30th percentile, Balanced to the 70th, High above. Our norms are provisional until the norming sample is complete. The bands and the Portrait names exist to make the result easier to talk about; the percentile is the measurement, and it is always shown alongside. Wellington is a wellness tool for reflection, not a medical or psychological diagnosis, and it does not replace care from a qualified professional. It is not couples counselling and it is not designed for hiring, and you can export or delete your data at any time. If you would like to read more first, see the methodology.

Questions people ask

What are the four attachment styles?

Secure, anxious or preoccupied, dismissing-avoidant and fearful-avoidant. They are not four kinds of person but four corners of a space made by two continuous scales, attachment anxiety and attachment avoidance (Fraley et al., 2000). Secure is low on both. Most people sit somewhere between the corners, which is why a label often fits only partly.

Is attachment style the same as personality?

No, though they overlap. Attachment anxiety is substantially related to Neuroticism, while attachment avoidance relates more weakly to lower Agreeableness and lower Extraversion (Noftle & Shaver, 2006). Attachment describes what happens when a close bond feels uncertain; personality traits describe broader tendencies across every part of life. Each tells you something the other does not.

Can your attachment style change?

The dimensions are treated as reasonably stable patterns rather than fixed settings, and both relationships and deliberate effort can move them. The personality dimension nearest attachment anxiety is one of the clearest examples of adult change: people tend to become more emotionally stable through adulthood (Roberts et al., 2006), and trait change through intervention runs to about a third of a standard deviation over roughly six months, largest for Emotional Stability (Roberts et al., 2017).

Does an anxious or avoidant result mean a relationship will not work?

No. The associations between attachment scores and relationship quality are real but modest averages across many couples (Noftle & Shaver, 2006), and the same is true of the personality links (Malouff et al., 2010). A score describes a tendency you can name and plan around, particularly around how quickly distress arrives and how repair happens after it.
