The Liebowitz Social Anxiety Scale (LSAS) is a 24-item, self-rated scale used to assess how social anxiety plays a role in your life across a variety of situations. The LSAS was developed by psychiatrist and researcher Dr. Michael R. Liebowitz.

The scale might be used in research studies to determine the level of social anxiety experienced by participants, in clinical settings to assess a particular patient's symptoms, or by people who are concerned that what they are experiencing might be the signs of an anxiety disorder.

Experts now recommend routine anxiety screening for all women and girls over the age of 13, so the LSAS is one type of screening tool that you may encounter during a routine doctor's visit.

At a Glance

If you think you might have social anxiety disorder (SAD), the Liebowitz Social Anxiety Scale can help evaluate your symptoms. The questions on the assessment identify a wide variety of social situations and then ask you to rate the degree of fear and avoidance you experience for each situation. The test is a quick, cost-effective way to accurately determine whether a person might have a problem with social anxiety. You can take the LSAS online for free, but only a doctor or mental health professional can diagnose social anxiety disorder. If you believe you have SAD, talk to your doctor or therapist to learn more about your treatment options.

How the LSAS Is Administered

The Liebowitz Social Anxiety Scale assesses both your social anxiety in situations as well as your avoidance of those situations. In this way, each item on the LSAS describes a situation in which you must answer the following questions.

Anxiety Questions (how anxious or fearful you feel)
  • 0 = none

  • 1 = mild

  • 2 = moderate

  • 3 = severe

Avoidance Questions (how often you avoid the situation)
  • 0 = never

  • 1 = occasionally

  • 2 = often

  • 3 = severe

If a question describes a situation that you do not ordinarily experience, you are asked to imagine how you would respond if faced with the situation. All questions are answered based on how the situations have affected you in the past week.

Questions on the Liebowitz Social Anxiety Scale

Below are some sample situations from the questionnaire:

  • Using a telephone in public
  • Participating in a small group activity
  • Eating in public
  • Talking to a person in authority
  • Being observed while working
  • Meeting people you don't know
  • Speaking during a meeting
  • Making eye contact with people you don't know well
  • Giving a speech

This is just a brief list, and the LSAS covers many other types of situations that are commonly known to trigger social anxiety performance anxiety and concerns. Situations that can commonly lead to social anxiety symptoms include interacting with strangers, making phone calls, and encountering unfamiliar social settings.

What Your LSAS Score Means

The Liebowitz Social Anxiety Scale is scored by summing the item ratings. Below are the suggested interpretations for various score ranges.

  • 55–65: Moderate social phobia
  • 65–80: Marked social phobia
  • 80–95: Severe social phobia
  • Greater than 95: Very severe social phobia

As with any self-report instrument, scores on the Liebowitz Social Anxiety Scale need to be interpreted by a qualified mental health professional and followed up with a full diagnostic interview for social anxiety disorder (SAD) when warranted.

Accuracy of the Liebowitz Social Anxiety Scale

Studies have shown the LSAS to be an effective and cost-efficient way to identify people with problems with social anxiety. Research indicates that the scale is reliable and valid for measuring global social anxiety.

Another study concluded that the LSAS measures the same trait in the same way across all expressions of social anxiety symptoms. The researchers concluded that the scale is a good tool for assessing, screening, and researching social anxiety.

However, a single instrument can't be used to make a diagnosis.

A clinical diagnosis of SAD can only be made based on an interview conducted by a trained mental health professional such as a psychologist, psychiatrist, or social worker.

Taking the Liebowitz Social Anxiety Scale

Your doctor or therapist may administer the Liebowitz Social Anxiety Scale, but you should also know that the LSAS is freely available for you to complete online if you wish. If you complete the test and find the results concerning, be sure to check with your doctor about what they might mean.

Your results may point to social anxiety, but it is essential to talk to a doctor or mental health professional to evaluate your symptoms and rule out other potential causes.

While an assessment such as the LSAS can be informative, it's only in the context of a larger evaluation that the cause of your symptoms can be determined and a course of action planned.

Other Social Anxiety Assessments

Other self-report social anxiety measures include the Social Phobia Inventory (SPIN), the Social Phobia and Anxiety Inventory (SPAI), the Social Phobia Scale (SPS), and the Social Interaction Anxiety Scale (SIAS).

Diagnosing Social Anxiety

If you are concerned that you may be living with symptoms of anxiety or avoidance, make an appointment with your primary care physician to discuss the next steps.

If this feels hard to do, consider making an appointment for general mental health concerns, and then when you meet with your doctor, bring along a copy of the LSAS as well as a written statement of what you have been experiencing.

Depending on your health insurance, you can also make an appointment with a mental health professional without consulting your primary care doctor.

Treatments That Can Help Social Anxiety

Know that you are not alone in the way that you are feeling and that your doctor can either conduct an assessment or refer you to a mental health professional who can provide a diagnosis and treatment options such as medication or talk therapy.

Cognitive-Behavioral Therapy

Social anxiety disorder is often treated with cognitive-behavioral therapy (CBT), an approach focused on helping people change the underlying thoughts and behaviors that contribute to social fear and avoidance. 

Exposure Therapy

Exposure therapy can also help people learn to manage social situations. In this approach, people practice being exposed to the social situations they fear, either in real life or by imagining the situation. Over time and with more exposure, feelings of fear begin to diminish.

Medications

Zoloft (sertraline), Paxil (paroxetine), and Effexor (venlafaxine) are FDA-approved to treat social anxiety disorder. Other medications may also be prescribed off-label, including other SSRIs, SNRIs, MAOIs, beta-blockers, and benzodiazepines.
