Body Dysmorphia Test

The BDDQ (Body Dysmorphic Disorder Questionnaire) is a brief self-report screen for body dysmorphic disorder: it asks about preoccupation with a perceived flaw in appearance, the time it takes, and the distress or impairment it causes.

BDD isn't vanity or insecurity. It's a clinical condition where the brain gets stuck on a perceived flaw, one that others often can't even see, and keeps pulling you back to check, compare, and hide. This test helps you recognize those patterns.

What does BDD feel like?

Body dysmorphic disorder is a preoccupation with one or more perceived flaws in your physical appearance, flaws that feel obvious and glaring to you, but that other people say they can't see, or barely notice. The preoccupation isn't passing self-consciousness. It occupies hours of your day.

People with BDD know, intellectually, that their concern might be excessive. But that knowledge doesn't make the compulsive mirror-checking, skin-picking, comparing, camouflaging, and avoidance stop. The drive to check and fix is neurologically similar to OCD, which is why BDD now sits in the OCD-related disorders section of DSM-5-TR.

"BDD causes severe impairment and is associated with high rates of suicidal ideation, often because people feel unable to seek help due to shame, or because their concerns are dismissed as 'just' being insecure."

Katharine Phillips, Oxford Handbook of Anxiety Disorders.

If you're looking this up, you deserve to take it seriously. BDD is not about being vain. It is a real, treatable condition.

What does the BDDQ measure?

The Body Dysmorphic Disorder Questionnaire (BDDQ) is a brief self-report screen developed by Katharine Phillips and colleagues. It screens across four core domains:

• Perceived flaw — You are preoccupied with a part of your appearance that you believe looks abnormal, unattractive, or deformed, and others say the flaw is absent or minor.
• Time and intrusiveness — The preoccupation occupies at least one hour per day on most days and feels difficult to control or dismiss.
• Distress or impairment — The concern causes you significant emotional distress (anxiety, shame, low mood) or gets in the way of daily functioning — for example, avoiding school, work, or social situations because of it.
• Not solely weight or shape — The preoccupation is not limited to concerns about being too fat or about your overall body weight or shape. (If it is, an eating disorder evaluation may be more appropriate — see the comparison section below.)

How do you give the BDDQ?

The BDDQ is completed by the person being screened. Answer based on how you have felt in the past month. This screener is aligned with the BDDQ developed by Phillips and colleagues; it is a first-step screen, and a positive result is followed by a fuller clinical interview.

How do you score and interpret the BDDQ?

The BDDQ is not scored as a numeric total with severity bands. A screen is positive when the answers indicate all of these:

• preoccupation with a perceived flaw,
• enough time spent on it,
• significant distress or impairment, and
• a concern not limited to body weight or shape.

A positive screen does not confirm a diagnosis; it indicates that a clinical interview is warranted. Severity in people diagnosed with BDD is rated separately, with the clinician-administered BDD-YBOCS (see the BDD test page).

Psychometric properties

In a validation study in a community sample of Swedish women ^[5], the BDDQ was completed by 2,891 women and validated in a subsample of 88 against the Structured Clinical Interview for DSM-IV (SCID) plus clinical assessment. It showed good concurrent validity, with a sensitivity of 94%, a specificity of 90% and a likelihood ratio of 9.4.

Limitations

• Screening, not diagnosis. A positive BDDQ indicates that a clinical interview is warranted; a diagnosis requires a qualified clinician who can rule out other conditions.
• Self-report. Shame and secrecy are common in BDD, and insight ranges from good to absent, so people may under-report or misjudge their symptoms.
• Validated populations. The community validation cited here was in Swedish women; accuracy may differ in men, adolescents and other settings.
• No severity measure. The BDDQ identifies a likely case but does not track severity or treatment response.

What body areas does BDD focus on?

BDD can attach to almost any body area. Most people with BDD are preoccupied with multiple areas simultaneously. The most common concerns, reported in epidemiological studies of BDD presentations, include:

The number of preoccupied areas tends to increase over time if BDD is not treated. Preoccupation with one area does not exclude simultaneous concerns about others.

BDD vs normal appearance concerns vs eating disorders

These three categories overlap in surface symptoms but differ substantially in focus, mechanism, and treatment. Accurate distinction matters because the treatments are different.

People can have both BDD and an eating disorder simultaneously; the conditions are not mutually exclusive. When BDD preoccupation is limited to body weight or the fear of being fat, only an eating disorder diagnosis is given — per DSM-5-TR Criterion C for BDD. A clinician must assess which concerns are primary and which may be co-occurring.

Normal appearance dissatisfaction is ubiquitous and does not on its own indicate pathology. The clinical threshold for BDD is reached when preoccupation is consuming, difficult to control, and directly impairs how a person functions in daily life.

DSM-5-TR BDD diagnostic criteria

DSM-5-TR (2022) defines body dysmorphic disorder by four core criteria. These are clinical paraphrases — clinicians should consult the DSM-5-TR text directly for diagnostic purposes.

Criterion A — Preoccupation with perceived appearance defects. The person is preoccupied with one or more perceived flaws or defects in their physical appearance that are not observable by others, or that others consider slight.

Criterion B — Repetitive behaviours or mental acts. At some point during the course of the disorder, the person performs repetitive behaviours (e.g., mirror-checking, excessive grooming, skin-picking, reassurance-seeking) or mental acts (e.g., comparing appearance to others) in response to the appearance concerns.

Criterion C — Clinically significant distress or impairment. The preoccupation causes clinically meaningful distress or significant impairment in social, occupational, or other important areas of functioning.

Criterion D — Not better explained by an eating disorder. If the preoccupation is exclusively about body fat or weight in a person who meets criteria for an eating disorder, that diagnosis takes precedence.

Specifiers in DSM-5-TR:

• With muscle dysmorphia — preoccupation that the body is too small or insufficiently muscular, even when well-built; more common in males.
• Insight specifier — clinicians specify whether beliefs about the perceived flaw are held with good or fair insight, poor insight, or are absent (delusional). BDD spans this entire range; those at the absent-insight end were historically misdiagnosed as having delusional disorder but respond to BDD-specific treatments rather than antipsychotics alone.

These criteria reflect the decision in DSM-5 to move BDD from the somatoform category into the OCD and Related Disorders chapter, capturing its compulsive, repetitive quality and its overlap with OCD.

What treatments work for BDD?

Cosmetic procedures do not treat BDD. The treatments with trial evidence are psychological and pharmacological ^[4].

Cognitive-behavioural therapy (CBT) with exposure and response prevention. A 2016 meta-analysis of 7 randomized controlled trials (N = 299) found CBT superior to waitlist or a credible psychological placebo ^[2]:

• BDD symptoms: δ = −1.22 (95% CI −1.66 to −0.79) ^[2].
• Depression symptoms: also reduced.
• Follow-up: gains maintained at 2 to 4 months.

CBT for BDD typically includes exposure to feared situations, response prevention (stopping compulsive checking and camouflaging), perceptual retraining to counteract biased self-perception, and cognitive restructuring of appearance-related beliefs ^[3].

Serotonin reuptake inhibitors (SRIs/SSRIs). SRIs are considered the medication of choice for BDD, and with CBT a first-line treatment ^[6]. A Cochrane review found fluoxetine superior to placebo, and clomipramine superior to desipramine, in reducing BDD symptom severity ^[4].

Practical questions such as dose and how long to continue a medication trial are covered in a clinical review ^[6].

Combined treatment. For moderate to severe presentations, CBT and SRI medication are commonly combined. There is little head-to-head trial evidence comparing combined treatment with either alone ^[2].

What does not work. Cosmetic procedures, including surgery, dermatological treatments and dental procedures targeting the perceived flaw, do not address BDD's underlying mechanism. People often report that cosmetic treatment fails to reduce preoccupation or triggers new concerns about adjacent areas. Seeking cosmetic procedures is a warning sign, not a treatment pathway.
