Abstract
The Liebowitz Social Anxiety Scale (LSAS) is a widely utilized psychometric instrument developed to assess the severity and range of symptoms associated with Social Anxiety Disorder (SAD), often historically referred to as social phobia. Developed by Michael R. Liebowitz in 1987, the scale presents respondents with 24 common social and performance situations. For each situation, the individual provides a dual rating: the degree of fear or anxiety experienced, and the extent to which they typically avoid the situation. The resulting total score helps clinicians and researchers classify the severity of the anxiety, ranging from mild to very severe social phobia.

Purpose
The primary purpose of the Liebowitz Social Anxiety Scale (LSAS) is to provide a comprehensive, quantitative measure of the distress and impairment caused by social anxiety symptoms. It serves as a crucial diagnostic aid for clinicians, helping to determine if an individual meets the criteria for Social Anxiety Disorder as defined by diagnostic manuals like the DSM.
Beyond diagnosis, the LSAS is extensively used in clinical trials and treatment monitoring. By assessing both the subjective emotional component (fear/anxiety) and the behavioral component (avoidance), the scale offers a robust tool for tracking symptomatic changes over time, thus evaluating the effectiveness of pharmacological or psychotherapeutic interventions.
Construct
The LSAS measures the core features of Social Anxiety Disorder, which include excessive fear, anxiety, and subsequent avoidance of situations where the individual may be scrutinized or judged by others. The scale is designed to capture the full spectrum of social phobia across two primary domains: Social Interaction and Performance situations.
The unique strength of the LSAS lies in its dual-rating system. Participants rate their feelings of fear (affective component) and their behavioral response (avoidance component) separately for each of the 24 items. This distinction allows for a nuanced understanding of the disorder, recognizing that fear and avoidance, while highly correlated, are distinct dimensions of the social anxiety construct.
Validity
The LSAS demonstrates strong evidence of convergent, discriminant, and criterion validity across numerous studies. Convergent validity is evidenced by high correlations between the LSAS total score and other established measures of social anxiety, such as the Social Interaction Anxiety Scale (SIAS) and the Social Phobia Scale (SPS).
Criterion validity is supported by the scale’s ability to effectively differentiate between individuals diagnosed with SAD and healthy control groups, as well as its sensitivity to change following treatment. Furthermore, the cut-off scores derived from clinical research are highly effective in establishing diagnostic thresholds, aligning well with structured clinical interviews based on DSM criteria.
Reliability
The LSAS possesses excellent psychometric properties, particularly regarding reliability. High levels of internal consistency have been consistently reported across diverse samples. For instance, research by Fresco et al. (2001) indicated a high Cronbach’s alpha coefficient of 0.95 for clinical samples and 0.94 for non-clinical samples, suggesting that the items reliably measure the same underlying construct.
The scale also exhibits high test-retest reliability, indicating stable scores when administered to participants over short periods in the absence of therapeutic intervention. This stability confirms the instrument’s suitability for longitudinal studies and accurate measurement of chronic symptoms.
Factor Analysis
While originally conceived as a unidimensional scale, subsequent factor analytic studies often support a robust two-factor model, corresponding directly to the nature of the social situations presented. These two primary factors are:
Performance Anxiety: Situations involving being observed, speaking, writing, or acting while under scrutiny (e.g., public speaking, working while observed, taking a test).
Social Interaction Anxiety: Situations involving initiating or maintaining conversation, meeting strangers, or dealing with people in authority (e.g., using a telephone in public, talking face-to-face with someone unknown).
These factors are often analyzed separately, yielding two subscale scores (Social Interaction score and Performance score), which, when added together with their respective avoidance ratings, contribute to the total LSAS score.
Instrument
Test Type: Clinician-administered or Self-report inventory
Format: 24 items, each rated on a dual 4-point Likert scale (0-3) for Fear/Anxiety and Avoidance.
Language Available: English (original), with numerous validated translations available globally (e.g., Spanish, German, Japanese).
Population Group: Clinical psychiatric patients and non-clinical community samples.
Age Group: Adolescents and Adults.
Population Details: Used primarily for individuals presenting with symptoms of excessive social fear, shyness, or phobia.
Test Methodology: The total score is calculated by summing the Fear/Anxiety ratings and the Avoidance ratings across all 24 items, yielding a maximum possible score of 144. Scoring thresholds are used to categorize severity:
0–54: Mild Social Anxiety
55–65: Moderate Social Anxiety
66–80: Marked Social Anxiety
81–95: Severe Social Anxiety
Greater than 95: Very Severe Social Phobia (Anxiety)

Permissions & Fee and Test Year
The LSAS was originally published in 1987 by Michael R. Liebowitz. While the scale is widely used in academic and clinical settings, users should consult the original author or associated institutions regarding specific permissions for commercial use or large-scale distribution. The instrument itself is frequently made available for research purposes, often without charge.

The Liebowitz Social Anxiety Scale (LSAS)
Liebowitz, 1987
Here are 24 social situations for you to consider. In the first column, rate your level of fear on a scale of 0 (meaning no fear) to 3 (meaning total fear). Circle the number. In the second column, rate how much you would avoid the situation on a scale of 0 (meaning no avoidance) to 3 (meaning total avoidance). Circle the number.
