Alexithymia Awareness Network

Diagnosis & Assessment

Understand assessment without self-diagnosis.

Alexithymia is usually treated in the research literature as a dimensional construct, not as a stand-alone clinical diagnosis. In practice, this means assessment tools can help describe patterns in emotional awareness and communication, but a score by itself does not diagnose a person (Taylor, Bagby, and Parker, 1997; Luminet, Nielson, and Ridout, 2021).

Use this for orientation. Bring personal mental-health, trauma, medication, or treatment questions to a qualified clinician.

Short answer

  • There is no simple checklist that can diagnose alexithymia.
  • Questionnaires and interviews are measurement tools. They need interpretation in context.
  • Self-screening can be useful for reflection or for preparing questions, but it is not a clinical conclusion.
  • A clinician may also consider mood, anxiety, trauma, autism, ADHD, medical symptoms, substance use, language/culture, and other factors that can affect emotional awareness.

What assessment can and cannot answer

Assessment can help describe patterns such as difficulty identifying feelings, difficulty describing feelings, or a more externally focused thinking style. It can also help researchers compare groups or track change over time.

Assessment cannot prove what someone “really” feels, replace a clinical evaluation, or decide whether another condition is present. Similar outward signs — for example emotional numbness, few feeling words, or a focus on body symptoms — can have different causes in different people.

Common alexithymia measures

The instruments below are included because they are common in the alexithymia literature. Listing a measure here does not mean AAN recommends self-diagnosis or unsupervised clinical interpretation.

Toronto Alexithymia Scale (TAS-20)

The TAS-20 is a widely used 20-item self-report questionnaire developed by Bagby, Parker, and Taylor. It measures three commonly discussed facets: difficulty identifying feelings, difficulty describing feelings, and externally oriented thinking (Bagby, Parker, and Taylor, 1994).

TAS-20 cutoff scores are often used in research and screening contexts. They should not be presented as a diagnosis, and a high or low score should be interpreted with attention to the person, setting, language, purpose of assessment, and co-occurring concerns.

Bermond–Vorst Alexithymia Questionnaire (BVAQ)

The BVAQ is another self-report alexithymia measure. Its validation paper describes cognitive and affective dimensions of alexithymia, including identifying, verbalizing, analyzing, emotionalizing, and fantasizing (Vorst and Bermond, 2001).

As with other self-report measures, the result is a structured description of responses, not a stand-alone clinical judgment.

Perth Alexithymia Questionnaire (PAQ)

The PAQ is a newer self-report measure that separately assesses difficulties identifying and describing feelings for negative and positive emotions, alongside externally oriented thinking (Preece, Becerra, Robinson, Dandy, and Allan, 2018).

Toronto Structured Interview for Alexithymia (TSIA)

The TSIA is a structured interview measure developed to assess alexithymia through an interview format rather than self-report alone (Bagby, Taylor, Parker, and Dickens, 2006). Interview-based assessment may give different information than a questionnaire, but it still requires trained interpretation and is not a public self-diagnosis tool.

Observer Alexithymia Scale (OAS)

The OAS is an observer-rated measure completed by someone who knows the person being assessed (Haviland, Warren, and Riggs, 2000). Observer reports can add another perspective, but they can also reflect relationship context, expectations, bias, or limited access to a person’s inner experience.

Adjacent emotion-awareness measures

Some tools, such as the Levels of Emotional Awareness Scale (LEAS), measure related constructs rather than alexithymia itself (Lane, Quinlan, Schwartz, Walker, and Zeitlin, 1990). These can be useful in research or clinical formulation, but they should not be collapsed into “an alexithymia test” without careful explanation.

Using a self-screen thoughtfully

A self-screen can be a starting point if it helps you notice patterns or prepare for a conversation. It is safer to treat results as prompts:

  • Which items felt easy, confusing, or hard to answer?
  • Do the results match your lived experience, or do they miss something important?
  • Were you answering during depression, burnout, acute stress, dissociation, substance use, or physical illness?
  • Did language, culture, disability, trauma history, or neurodivergence affect how the questions landed?
  • What examples would you want a clinician to understand?

If an online test gives you a label, certainty score, treatment plan, or prediction about your future, be cautious. A responsible screen should explain limits and encourage clinical consultation when symptoms, distress, functioning, trauma, safety, or treatment questions are involved.

What a clinician may consider

A clinician does not need to rely on one alexithymia score alone. Depending on the setting and the person’s goals, assessment may include:

  • current concerns and why assessment is being considered;
  • history of emotional awareness, communication, relationships, and body sensations;
  • mood, anxiety, trauma, dissociation, neurodevelopmental history, medical symptoms, sleep, medication, and substance-use context;
  • examples of how the person recognizes distress, asks for support, or handles conflict;
  • standardized measures when they are appropriate for the setting;
  • discussion of what the results do and do not mean.

This is especially important because alexithymia can overlap with or co-occur alongside other experiences. The goal is not to force every difficulty into one label, but to understand what support, accommodations, or further evaluation may be useful.

When to seek professional help

Consider reaching out to a qualified professional if emotional confusion or numbness is causing distress, relationship conflict, work or school problems, risky coping, trauma symptoms, severe anxiety or depression, medical concerns, substance-use concerns, or questions about medication or treatment.

If safety is uncertain or immediate help is needed, AAN is not the right support channel. Use qualified local support or services equipped for immediate safety needs.
