Avoidant personality disorder: how it differs from social anxiety and what helps

The APA Dictionary of Psychology describes avoidant personality disorder as a lasting pattern in which a person is acutely sensitive to rejection and criticism, longs to be accepted without being judged, pulls back from people even while wanting warmth and approval, and thinks poorly of themselves, to a degree that causes real distress and badly disrupts work and relationships (APA, n.d.). The heart of it is not disliking people: it is wanting to be close and staying away for fear of being turned down. The US diagnostic manual (DSM-5-TR) considers the diagnosis when social inhibition, a sense of being inadequate and oversensitivity to negative judgement begin by early adulthood at the latest and run through many areas of life (Zimmerman, 2023). This guide does not print the list of criteria.

In Korea’s medical records, which follow the ICD-10 system, the condition is filed as “anxious [avoidant] personality disorder” (F60.6) (WHO, 1992; Health Insurance Review and Assessment Service, 2026). The World Health Organization’s newer ICD-11, by contrast, has no separate category called avoidant personality disorder. It treats personality disorder as one diagnosis and adds its severity and its most prominent trait domains, a model set out in the guide Borderline personality disorder. In the table ICD-11 provides for translating its diagnoses back into ICD-10, the closest match to the old avoidant category is a personality disorder with the negative affectivity and detachment trait domains (WHO, 2024). Detachment here does not mean distance in the attachment sense; it is a personality trait of avoiding social contact and closeness itself. The NHS likewise explains that diagnosis is changing, and that instead of a named type you may be diagnosed with mild, moderate or severe personality disorder with particular traits (NHS, 2024).

mind.io does not offer an avoidant personality test. A diagnosis does not come from a single score: a professional looks directly at long-standing patterns across situations, the distress they cause and how much they get in the way of life (Zimmerman, 2023; WHO, 2024). This guide sets out how avoidant personality disorder can show up, how it differs from shyness, social anxiety disorder and avoidant attachment, how common it is and how it changes, why it develops and persists, and which treatments have evidence and where to get help. It is not meant for putting a label on someone else.

People with avoidant personality disorder want company but are afraid to let how they feel depend on other people. When they look tense, others sometimes tease them, and that can feel like proof of what they already fear about themselves, which keeps the cycle going (Zimmerman, 2023). Researchers see two things at its core: a sense of being inferior to others and an expectation of being rejected (Lampe & Malhi, 2018). A single rejection can therefore feel like a verdict that you are worthless as a whole person (Lampe, 2015).

In daily life it can look like steering clear of jobs that involve dealing with many people or of situations where you might be embarrassed (McGlashan et al., 2005), and finding it hard to open up even in close relationships for fear of being belittled (American Psychiatric Association, 2024). The avoidance does not always stop at people. Across four studies, avoidant personality traits were weakly to moderately linked with avoiding uncomfortable feelings and new things as well (Taylor et al., 2004). ICD-11 also notes that people high in negative affectivity tend to react very strongly to criticism, perceived threats and setbacks, and may stay away from situations they judge too hard even when the evidence says they could manage (WHO, 2024).

A review of avoidant personality disorder describes how mixed feelings about people, wanting them and fearing them, together with self-doubt, harsh self-criticism and a habit of putting others first, make it hard to know what you want and to act on it (Weme et al., 2023). Having some of these traits is not the same as having a disorder, though. ICD-11 points out that the way people raised in collectivist cultures relate to others can look “avoidant” by individualistic standards, and says personality disorder should be diagnosed only when the pattern goes beyond what is ordinary in that society (WHO, 2024). A quiet, reserved person is not automatically someone with a disorder.

Shyness and introversion are ordinary personality traits that everyone has to some degree. Introversion is a broad trait on which people vary, and very shy people may be at greater risk of social anxiety disorder (APA, n.d.). A review found evidence that shyness, social anxiety disorder and avoidant personality disorder lie on a continuum, but suggested that what makes up that continuum may need rethinking (Rettew, 2000). A personality disorder means the distress and disruption to life are large and long-lasting (APA, n.d.). The difference between introversion and high sensitivity is covered in Highly sensitive person vs introvert.

There is a large overlap with social anxiety disorder. In a survey that interviewed more than 43,000 US adults, close to 40% of people with avoidant personality disorder also had social anxiety disorder, and having both went with a lower quality of life than social anxiety disorder alone. The researchers concluded that the two are closely related but may be separable (Cox et al., 2009). In community studies, about two thirds of people with avoidant personality disorder did not meet the criteria for social anxiety disorder (Lampe & Malhi, 2018). In a study that interviewed Norwegian female twins twice, ten years apart, the risk factors for the two disorders overlapped strongly (r = .76) but were not identical, and the share of people with avoidant personality disorder who also had social anxiety disorder rose from a third at the start to a half ten years later (Torvik et al., 2016). Other researchers regard avoidant personality disorder as a severe form of social anxiety disorder (Reich, 2009), so the debate is not settled. Ways to tackle social anxiety itself are in the guide Social anxiety disorder.

Despite the similar name, the avoidant attachment style is not the same as avoidant personality disorder. In attachment research, the dismissing style closest to “avoidant” means playing down the importance of close relationships and relying firmly on yourself (APA, n.d.), and a result on the attachment style test is not a diagnosis. A study comparing 90 Norwegian patients found that people with avoidant personality disorder had more attachment anxiety, the fear of being abandoned, than people with social anxiety disorder alone, and more often had a fearful style, wanting closeness and fearing it at once, which this site calls fearful-avoidant (Eikenaes et al., 2016). Avoidant attachment is covered in Coping with avoidant attachment.

High sensitivity (sensory processing sensitivity) is a different idea too. In a study of 127 university students, sensitivity scores were linked with avoidant personality traits (Meyer & Carver, 2000), but sensitivity is a temperament, not an illness (see Signs of a highly sensitive person). Unlike schizoid personality disorder, in which the wish for close relationships is itself weak, people with avoidant personality disorder want closeness and withdraw for fear of rejection (APA, n.d.; Zimmerman, 2023); and unlike dependent personality disorder, in which anxiety drives people to lean on someone more, they tend to pull away (Lampe & Malhi, 2018).

How common it is depends heavily on how it is measured. A US national survey counted avoidant personality disorder in 2.4% of adults, more often in women (Grant et al., 2004), but when the data were reanalysed so that each feature only counted if it actually caused distress or problems, the figure fell to 1.2% (Trull et al., 2010). A meta-analysis of community surveys from many countries put it at about 2.7%, the second most common personality disorder after obsessive-compulsive personality disorder (Winsper et al., 2020), while another meta-analysis of Western studies found 2.8%, dropping to 1.2% when only studies in which experts did the assessment were included (Volkert et al., 2018). A review of research from 1980 to 2020 placed community prevalence between 0.8% and 5% and noted that, although common, the condition is often missed and left untreated (Reich & Schatzberg, 2021).

There is no population-based estimate for Korea. The 2021 National Mental Health Survey had no module measuring personality disorders (NCMH, n.d.). In national health insurance data, 438 people were treated in 2025 with anxious [avoidant] personality disorder (F60.6) as their main diagnosis, more than half of them in their twenties, but that is only the number treated under that diagnosis, not the number of people living with it (Health Insurance Review and Assessment Service, 2026).

It can also change over time. In a US collaborative study that followed adults seeking treatment, half of those with avoidant personality disorder no longer met its criteria two years later, though by a stricter definition of clear improvement the rates were much lower, 23% to 38% across the four personality disorders studied (Grilo et al., 2004). What changed most readily was the avoidant behaviour, such as steering clear of jobs with a lot of contact with people or of potentially embarrassing situations; what stayed most persistently was the feeling of being inadequate and socially inept (McGlashan et al., 2005). Over ten years, the average level of the features fell steadily (Sanislow et al., 2009). ICD-11 likewise notes that personality disorder is fairly stable after young adulthood but may no longer meet the diagnostic requirements by middle age, adding that traits such as detachment are less likely to fade (WHO, 2024).

Nor is it something to brush off as just a shy personality. In a Norwegian population study, people with avoidant personality disorder were among those whose quality of life was reduced most broadly of all the personality disorders (Cramer et al., 2006); in the US collaborative study, their difficulties at work, in relationships and in leisure fell in the middle of the personality disorders studied (Skodol et al., 2002), and problems in relationships tended not to ease much over time (Skodol et al., 2005). Of 410 people diagnosed at a Norwegian specialist personality disorder clinic, 79.5% had been out of work for the whole six months before the study, although these were people who had sought treatment, so it does not apply to everyone (Sveen et al., 2025).

Several factors are thought to work together rather than a single cause. A review of research from 1980 to 2020 found a weighted average heritability of 0.55 (Reich & Schatzberg, 2021), and a Norwegian twin study found that its genetic risk overlapped heavily with that of social anxiety disorder (Torvik et al., 2016). Heritability is a statistic about differences within a population, though, not a personal destiny, and in the same study environmental factors mattered most for changes at particular points in time (Torvik et al., 2016). A review suggests that a partly heritable tendency to feel negative emotions readily and positive ones less, together with growing up with neglectful or emotionally cold caregiving, may set the stage for the negative self-image, proneness to shame and interpersonal oversensitivity seen in avoidant personality disorder (Lampe, 2016).

In a study comparing 91 Norwegian patients, those with avoidant personality disorder reported more childhood neglect, especially physical neglect, than those with social anxiety disorder alone (Eikenaes et al., 2015), and a meta-analysis of 48 studies found that difficult childhood experiences were consistently linked with cluster C personality disorders, avoidant included (Crișan et al., 2023). Most of these studies ask adults to remember their childhood at a single point in time, however, so they neither prove a cause nor justify blaming parents. Many people with such experiences never develop the disorder.

There is a loop that keeps avoidance going. Researchers describe withdrawing from people as one way of escaping shame that is felt now or seems about to come (Schoenleber & Berenbaum, 2012). It may bring relief right away, but it also leaves fewer chances to find out whether the feared outcome is real. One interpretation is that holding feelings tightly in to avoid rejection can come across as distant and end up inviting rejection (Lampe & Malhi, 2018). Pulling back even from relationships you want can also deepen loneliness, though few studies have measured this directly (Reinhard et al., 2022). Ways to deal with loneliness are in Loneliness: what helps.

In a Korean survey of 222 people aged 13 to 24, the group with the strongest reclusive tendencies had the highest depression and avoidant personality scale scores and the least emotional support, but it was a one-time survey of a convenience sample, so it is hard to generalise (Lee & Cha, 2026). If going out of the house at all has become hard, prolonged withdrawal and where to get help are described in the guide Hikikomori (prolonged social withdrawal). Avoidant personality disorder often comes with depression or substance use problems and is likely to go with a higher risk of suicidal thoughts and attempts (Lampe & Malhi, 2018). If you have thoughts of harming yourself, please do not carry them alone. Reach out to a crisis line right away: call or text 988 in the US and Canada, call Samaritans on 116 123 in the UK and Ireland, or find a line at findahelpline.com elsewhere. If you are in immediate danger, contact your local emergency services.

Few studies have looked at avoidant personality disorder on its own. A 2016 review called it a neglected disorder while concluding that the evidence for cognitive behavioural therapy (CBT) and schema therapy is promising (Weinbrecht et al., 2016). In a Dutch trial that randomly assigned 62 people to 20 weeks of CBT, 20 weeks of brief psychodynamic therapy or a waiting list, CBT did better than both, and brief psychodynamic therapy did no better than the waiting list: six months after treatment, 9% of the CBT group still met the criteria, against 36% of the brief psychodynamic group. It was a single small study, which should be kept in mind (Emmelkamp et al., 2006). In an early randomised trial of a ten-week group treatment, graded exposure, approaching feared situations a little at a time, was enough on its own to bring clear improvement over an untreated group, and adding social skills training did not boost the effect, although by the end of treatment people had not yet reached typical levels (Alden, 1989).

Other treatments have evidence too. In a trial that assigned 50 people with cluster C personality disorders, including avoidant, to 40 sessions of short-term psychodynamic therapy or cognitive therapy, the two treatments did not differ; two years later, 54% and 42% respectively had recovered in terms of symptoms, and around 40% in both groups in terms of relationships and personality functioning (Svartberg et al., 2004). In a trial of 323 people with cluster C and other personality disorders at 12 Dutch centres, schema therapy, which works on long-standing patterns of belief and feeling (“schemas”), led to recovery in a larger share of people than usual care, with no difference between personality disorder types, although the difference showed up only in interview-based assessments, not in self-report questionnaires (Bamelis et al., 2014). In a trial of 154 people with both social anxiety disorder and avoidant personality disorder, group schema therapy and group CBT both brought substantial improvement with no difference between them, and more people completed group schema therapy (Baljé et al., 2024).

Taken together, gains from CBT, psychodynamic therapy and social skills training in cluster C personality disorders were usually maintained after treatment ended (Simon, 2009), and in borderline and cluster C personality disorders psychodynamic therapy did about as well as other active treatments (Keefe et al., 2020). There is no evidence yet that any one treatment is best. No medicine has been tested for avoidant personality disorder itself (Lampe & Malhi, 2018), so medicines are a doctor’s decision when treating depression or anxiety that comes with it. Apps or online programmes tested specifically for it are also hard to find: a review of 11 studies of internet programmes for personality disorders found that most dealt with borderline personality disorder (van der Boom et al., 2022).

Starting and staying in treatment can itself be hard. People with avoidant personality disorder are often reluctant to start or stay in treatment (Zimmerman, 2023), which is why it matters to recognise this early and work on it within therapy (Lampe, 2015). In a study that interviewed 15 people about their experience of treatment, they described an emotional bond and growing trust with the therapist as important for finding the courage to approach, little by little, what they feared (Sørensen et al., 2019). Whether personality traits can change with treatment is covered in Can personality change?.

We found no self-help programme designed and tested specifically for avoidant personality disorder, and a review of internet programmes for personality disorders found none aimed at it (van der Boom et al., 2022). The practices below are therefore drawn from what therapy works on, and they do not replace treatment. In therapy, approaching avoided situations in small steps (Alden, 1989), building tolerance for the distress of moments that feel like criticism or rejection, and trying to express feelings appropriately rather than hiding them are thought to be important (Lampe & Malhi, 2018).

1. List the situations you avoid from easiest to hardest, and start with the easiest. Methods used for social anxiety are in the guide Social anxiety disorder. 2. When you feel rejected, notice whether you are reading it as a verdict on you as a whole person (Lampe, 2015). 3. Instead of words that put yourself down, try speaking to yourself kindly, as you would to a friend; ways to practise are in How to build self-compassion. 4. Do not damp down tension with alcohol. In a reanalysis of a US national survey, about 35% of people with avoidant personality disorder had had alcohol dependence at some point in their lives, compared with about 12% of those without it (Trull et al., 2010). The guide Alcohol use disorder may also help.

A doctor or a mental health professional is a good place to start. In Korea, you can get help from a psychiatrist or a local community mental health welfare centre, and calling the mental health crisis line 1577-0199 (24 hours) connects you to a nearby centre (Ministry of Health and Welfare, 2025). If your mood has been low for more than two weeks, the depression check-in (PHQ-9) can show where you are now, and if anxiety is high, the anxiety check-in (GAD-7). Neither is a test for avoidant personality disorder.

Q. Is there an avoidant personality disorder test? A. mind.io does not offer an avoidant personality test. Research and clinical practice use interview tools and questionnaires, but this guide prints no items or cut-off scores. A diagnosis is made by a professional who looks directly at long-standing patterns, the distress they cause and how much they get in the way of life (Zimmerman, 2023). Please do not label yourself or anyone else on the strength of an online checklist.

Q. Is it the same as avoidant attachment? A. No. The avoidant attachment style describes a way of drawing close and pulling away in relationships, and it is not a diagnosis. Compared with patients who had social anxiety disorder alone, patients with avoidant personality disorder in fact showed more anxiety about being abandoned and more often had a fearful-avoidant style, wanting closeness while fearing it (Eikenaes et al., 2016). An “avoidant” result on the attachment style test does not mean you have avoidant personality disorder.

Q. How is it different from social anxiety disorder? A. The two overlap a lot but are not the same. At the core of avoidant personality disorder are a sense of being inferior to others and an expectation of rejection, and in the community about two thirds of people with it did not meet the criteria for social anxiety disorder (Lampe & Malhi, 2018). People with both had a lower quality of life than those with social anxiety disorder alone (Cox et al., 2009).

Q. Can it get better? A. It can change a great deal. In a study that followed people seeking treatment, half no longer met the criteria two years later (Grilo et al., 2004), and in randomised trials CBT and schema therapy helped (Emmelkamp et al., 2006; Bamelis et al., 2014). The feeling of being inadequate tends to last longer than the avoidant behaviour, though (McGlashan et al., 2005), so treatment should work on that feeling and on the sensitivity to negative judgement as well as on social inhibition (Weinbrecht et al., 2016).

Q. Do I need medication? A. No medicine has been tested for avoidant personality disorder itself (Lampe & Malhi, 2018). If depression or anxiety that comes with it is severe, a doctor can talk you through treatment options. Talking therapy is at the centre of treatment for personality disorders (NHS, 2024).

Q. I’m introverted. Could I have avoidant personality disorder? A. Introversion is an ordinary personality trait on which people vary (APA, n.d.). If you are comfortable spending time alone and do not mind seeing few people, that alone is not a disorder. Avoidant personality disorder means wanting people but avoiding them for fear of rejection, with distress and disruption to life that last a long time (APA, n.d.). You can explore your own tendencies in Highly sensitive person vs introvert.

Q. I think my partner or a family member has avoidant personality disorder. A. Diagnosis is a professional’s job, and this guide is not meant for putting a label on someone else. People with avoidant personality disorder are sensitive to rejection and criticism (APA, n.d.) and are often reluctant to seek treatment (Zimmerman, 2023), so listening without judgement may come before pushing. Ways to talk with a partner who keeps their distance are in How to talk to an avoidant partner.

Q. Avoiding people has left me so lonely that I want to disappear. A. Please do not carry that alone. Reach out to a crisis line right away: call or text 988 in the US and Canada, call Samaritans on 116 123 in the UK and Ireland, or find a line at findahelpline.com elsewhere. If you are in immediate danger, contact your local emergency services. The loneliness you feel now does not measure your worth as a person.
