Liebowitz social anxiety scale

Last updated

The Liebowitz Social Anxiety Scale (LSAS) is a short questionnaire developed in 1987 by Michael Liebowitz, a psychiatrist and researcher at Columbia University and the New York State Psychiatric Institute. [1] Its purpose is to assess the range of social interaction and performance situations feared by a patient in order to assist in the diagnosis of social anxiety disorder. It is commonly used to study outcomes in clinical trials and, more recently, to evaluate the effectiveness of cognitive-behavioral treatments. The scale features 24 items, which are divided into two subscales. 13 questions relate to performance anxiety and 11 concern social situations. The LSAS was originally conceptualized as a clinician-administered rating scale, but has since been validated as a self-report scale. [2]

Introduction

To assess social phobia, psychologists and clinicians need to distinguish between performance anxiety and social interaction anxiety in order to make an accurate diagnosis. Social phobia was included in the Diagnostic and Statistical Manual of Mental Disorders, third edition (DSM-III). [3] In the DSM-III-R and DSM-IV revisions, further expansion of the social phobia definition were included to better assess fears in social-interaction situations. [4] [5] Social phobia is defined by a persistent fear of embarrassment or negative evaluation while engaged in social interaction or public performance. However, lack of empirical data made it difficult to differentiate and relate different types of feared situations and social interactions. [6] The Liebowitz Social Anxiety Scale (LSAS) was the first clinician-administered scale developed for the assessment of fear and avoidance associated with social phobia. [1] The LSAS has a broad scope in assessment of both social interactions and performance/observation situations. Since its invention, the LSAS has been used in many cognitive-behavioral treatments of social phobia. The LSAS is the most frequently used form of social anxiety assessment in research, clinical-based, and pharmacotherapy studies. [6]

Scoring

The scale is composed of 24 items divided into 2 subscales, 13 concerning performance anxiety, and 11 pertaining to social situations. The 24 items are first rated on a Likert Scale from 0 to 3 on fear felt during the situations, and then the same items are rated regarding avoidance of the situation. [7] Combining the total scores for the Fear and Avoidance sections provides an overall score with a maximum of 144 points. The clinician administered version of the test has four more subscale scores, which the self-administered test does not have. These additional four subscales are: fear of social interaction, fear of performance, avoidance of social interaction and avoidance of performance. Usually, the sum of the total fear and total avoidance scores are used in determining the final score (thus, essentially it uses the same numbers as the self-administered test). Research supports a cut-off point of 30, in which SAD is unlikely. The next cut-off point is at 60, at which SAD is probable. Scores in this range are typical of persons entering treatment for the non-generalized type of SAD. Scores between 60 and 90 indicate that SAD is very probable. Scores in this range are typical of persons entering treatment for the generalized type of SAD. Scores higher than 90 indicate that SAD is highly probable. Scores in this range often are accompanied by great distress and difficulty in social functioning, and are also commonly seen in persons entering treatment for the generalized type of SAD. [2] [8] [9]

The specific subtype of social anxiety disorder involves fear of one or several kinds of social/performance situations (often public speaking.) [10]

The generalized subtype of social anxiety disorder is characterized by fear of most social/performance situations. [11]

Reliability and validity

Heimberg et al. (1992) found that scores on the Liebowitz Social Anxiety Scale were significantly correlated with scores of two other scales, which had demonstrated significant reliability and validity in several studies before. Those two scales are the Social Phobia Scale and the Social Interaction Anxiety Scale. [12] [13] [14] In another study, Heimberg et al. (1999) also found that the LSAS is closely related to other scales, including the HRSD, BDI and the HAMA.

Research found that the internal consistency of the LSAS is high, too. In a large study, LSAS scores were compared with scores for Total fear, Fear of social interaction, Fear of performance, Total avoidance, Avoidance of social interaction and Avoidance of performance. Scores for total fear and social interaction were extremely high with correlations of .94 and .92, respectively. [15]

It was also found that phenelzine was associated with LSAS scores that had post-treatment scores with standard deviations at least half higher than patients in placebo treatment. [15]

Safren and colleagues found that the relationship between social interactional anxiety and performance anxiety in their studies, showed high face validity but lacked construct validity. [6] This study and others suggest the need for more research based on empirical approaches.

LSAS self-report questionnaire

The LSAS has been used as a self-report measure (LSAS-SR). Studies by Baker and colleagues have shown a high reliability and validity to the self-report questionnaire, consistent with the clinician-administered version of the LSAS, with the only exception being the fear subscale of performance situations. All subscales measures show high test-retest reliability. However, some differences did exist between clinician and the self-report measures. For a full discussion see Baker [16] and Cox. [17] Research has also established the structural validity and other metric qualities (i.e., internal reliability, test-retest) of the French adaptation of the LSAS-SR. [18]

LSAS for children and adolescents (LSAS-CA)

Similarly to the regular LSAS, the LSAS-CA also has a clinician administered version of the rest and a self-report version (LSAS-CA-SR). In the clinician administered version, subjects with social anxiety disorder had significantly higher LSAS-CA scores than subjects with other anxiety disorders and healthy controls. [19] The study also showed high internal consistency and high test-retest reliability. The self-report version of the Scale has been extensively tested on the Spanish population, with results high in validity and reliability. They also found significant differences in the scores for some sub-scales (total fear) between males and females. [20] Recent studies have also established the structural validity of the French version of the test, including reliable internal consistency and other psychometric properties. [21]

Social inhibition is a conscious or subconscious avoidance of a situation or social interaction. With a high level of social inhibition, situations are avoided because of the possibility of others disapproving of their feelings or expressions. Social inhibition is related to behavior, appearance, social interactions, or a subject matter for discussion. Related processes that deal with social inhibition are social evaluation concerns, anxiety in social interaction, social avoidance, and withdrawal. Also related are components such as cognitive brain patterns, anxious apprehension during social interactions, and internalizing problems. It also describes those who suppress anger, restrict social behavior, withdraw in the face of novelty, and have a long latency to interact with strangers. Individuals can also have a low level of social inhibition, but certain situations may generally cause people to be more or less inhibited. Social inhibition can sometimes be reduced by the short-term use of drugs including alcohol or benzodiazepines. Major signs of social inhibition in children are cessation of play, long latencies to approaching the unfamiliar person, signs of fear and negative affect, and security seeking. Also in high level cases of social inhibition, other social disorders can emerge through development, such as social anxiety disorder and social phobia.

The Yale–Brown Obsessive–Compulsive Scale (Y-BOCS) is a test to rate the severity of obsessive–compulsive disorder (OCD) symptoms.

Social anxiety is the anxiety and fear specifically linked to being in social settings. Some categories of disorders associated with social anxiety include anxiety disorders, mood disorders, autism spectrum disorders, eating disorders, and substance use disorders. Individuals with higher levels of social anxiety often avert their gazes, show fewer facial expressions, and show difficulty with initiating and maintaining a conversation. Social anxiety commonly manifests itself in the teenage years and can be persistent throughout life; however, people who experience problems in their daily functioning for an extended period of time can develop social anxiety disorder. Trait social anxiety, the stable tendency to experience this anxiety, can be distinguished from state anxiety, the momentary response to a particular social stimulus. Half of the individuals with any social fears meet the criteria for social anxiety disorder. Age, culture, and gender impact the severity of this disorder. The function of social anxiety is to increase arousal and attention to social interactions, inhibit unwanted social behavior, and motivate preparation for future social situations.

The Beck Anxiety Inventory (BAI), created by Aaron T. Beck and other colleagues, is a 21-question multiple-choice self-report inventory that is used for measuring the severity of anxiety in adolescents and adults ages 17 and older. The questions used in this measure ask about common symptoms of anxiety that the subject has had during the past week. It is designed for individuals who are of 17 years of age or older and takes 5 to 10 minutes to complete. Several studies have found the Beck Anxiety Inventory to be an accurate measure of anxiety symptoms in children and adults.

DASS, the Depression Anxiety Stress Scales, is made up of 42 self-report items to be completed over five to ten minutes, each reflecting a negative emotional symptom. Each of these is rated on a four-point Likert scale of frequency or severity of the participants' experiences over the last week to emphasize states over traits. These scores ranged from 0, meaning that the client believed the item "did not apply to them at all", to 3, meaning that the client considered the item to "apply to them very much or most of the time". It is also stressed in the instructions that there are no right or wrong answers.

The Temperament and Character Inventory (TCI) is an inventory for personality traits devised by Cloninger et al. It is closely related to and an outgrowth of the Tridimensional Personality Questionnaire (TPQ), and it has also been related to the dimensions of personality in Zuckerman's alternative five and Eysenck's models and those of the five factor model.

Social anxiety disorder (SAD), also known as social phobia, is an anxiety disorder characterized by sentiments of fear and anxiety in social situations, causing considerable distress and impairing ability to function in at least some aspects of daily life. These fears can be triggered by perceived or actual scrutiny from others. Individuals with social anxiety disorder fear negative evaluations from other people.

Social Phobia Inventory (SPIN) is a questionnaire developed by the department of Psychiatry and Behavioral Sciences of Duke University for screening and measuring severity of social anxiety disorder. This self-reported assessment scale consists of 17 items, which cover the main spectrum of social phobia such as fear, avoidance, and physiological symptoms. The statements of the SPIN items indicate the particular signs of social phobia. Answering the statements a person should indicate how much each statement applies to him or her.

The Panic Disorder Severity Scale (PDSS) is a questionnaire developed for measuring the severity of panic disorder. The clinician-administered PDSS is intended to assess severity and considered a reliable tool for monitoring of treatment outcome. Self-report form of the Panic Disorder Severity Scale (PDSS-SR) is used to detect possible symptoms of panic disorder, and suggest the need for a formal diagnostic assessment.

Driving phobia, driving anxiety, vehophobia, amaxophobia or driving-related fear (DRF) is a pathological fear of driving. It is an intense, persistent fear of participating in car traffic that affects a person's lifestyle, including aspects such as an inability to participate in certain jobs due to the pathological avoidance of driving. The fear of driving may be triggered by specific driving situations, such as expressway driving or dense traffic. Driving anxiety can range from a mild cautious concern to a phobia.

Fear of negative evaluation (FNE) or fear of failure, also known as atychiphobia, is a psychological construct reflecting "apprehension about others' evaluations, distress over negative evaluations by others, and the expectation that others would evaluate one negatively". The construct and a psychological test to measure it were defined by David Watson and Ronald Friend in 1969. FNE is related to specific personality dimensions, such as anxiousness, submissiveness, and social avoidance. People who score high on the FNE scale are highly concerned with seeking social approval or avoiding disapproval by others and may tend to avoid situations where they have to undergo evaluations. High FNE subjects are also more responsive to situational factors. This has been associated with conformity, pro-social behavior, and social anxiety.

Social Phobia and Anxiety Inventory Brief, abbreviated as (SPAI-B), is a Spanish version of the Social Phobia and Anxiety Inventory. It evaluates the same psychological factors as SPAI related to cognition, behavior and somatic symptoms usually exhibited by persons with social anxiety. Although the psychometrics have been found to be sound, its utility as a screening measure is limited by its length. As an attempt to resolve this situation, Deborah Beidel from University of Central Florida (US), along with an international team led by Dr. Garcia-Lopez at the University of Jaen (Spain) developed this form in 2008.

The Spence Children's Anxiety Scale (SCAS) is a psychological questionnaire designed to identify symptoms of various anxiety disorders, specifically social phobia, obsessive-compulsive disorder, panic disorder/agoraphobia, and other forms of anxiety, in children and adolescents between ages 8 and 15. Developed by Susan H. Spence and available in various languages, the 45 question test can be filled out by the child or by the parent. Alternatively, an abbreviated form of the test has been developed, with only 19 questions. It has shown equally valid results while reducing stress and response burden in younger participants. There is also another 34 question version of the test specialized for children in preschool between ages 2.5 and 6.5. Any form of the test takes approximately 5 to 10 minutes to complete. The questionnaire has shown good reliability and validity in recent studies.

The Screen for Child Anxiety Related Emotional Disorders (SCARED) is a self-report screening questionnaire for anxiety disorders developed in 1997. The SCARED is intended for youth, 9–18 years old, and their parents to complete in about 10 minutes. It can discriminate between depression and anxiety, as well as among distinct anxiety disorders. The SCARED is useful for generalized anxiety disorder, social anxiety disorder, phobic disorders, and school anxiety problems. Most available self-report instruments that measure anxiety in children look at general aspects of anxiety rather than Diagnostic and Statistical Manual of Mental Disorders (DSM) categorizations. The SCARED was developed as an instrument for both children and their parents that would encompass several DSM-IV and DSM-5 categorizations of the anxiety disorders: somatic/panic, generalized anxiety, separation anxiety, social phobia, and school phobia.

The Social Interaction Anxiety Scale (SIAS) is a self-report scale that measures distress when meeting and talking with others that is widely used in clinical settings and among social anxiety researchers. The measure assesses social anxiety disorder, which is fear or anxiety about one or more social situations where the individual is subject to possible scrutiny.

The Dimensional Obsessive-Compulsive Scale (DOCS) is a 20-item self-report instrument that assesses the severity of Obsessive-Compulsive Disorder (OCD) symptoms along four empirically supported theme-based dimensions: (a) contamination, (b) responsibility for harm and mistakes, (c) incompleteness/symmetry, and (d) unacceptable (taboo) thoughts. The scale was developed in 2010 by a team of experts on OCD led by Jonathan Abramowitz, PhD to improve upon existing OCD measures and advance the assessment and understanding of OCD. The DOCS contains four subscales that have been shown to have good reliability, validity, diagnostic sensitivity, and sensitivity to treatment effects in a variety of settings cross-culturally and in different languages. As such, the DOCS meets the needs of clinicians and researchers who wish to measure current OCD symptoms or assess changes in symptoms over time.

The Clinically Administered PTSD Scale (CAPS) is an in-person clinical assessment for measuring posttraumatic stress disorder (PTSD). The CAPS includes 30 items administered by a trained clinician to assess PTSD symptoms, including their frequency and severity. The CAPS distinguishes itself from other PTSD assessments in that it can also assess for current or past diagnoses of PTSD.

The Child PTSD Symptom Scale (CPSS) is a free checklist designed for children and adolescents to report traumatic events and symptoms that they might feel afterward. The items cover the symptoms of posttraumatic stress disorder (PTSD), specifically, the symptoms and clusters used in the DSM-IV. Although relatively new, there has been a fair amount of research on the CPSS due to the frequency of traumatic events involving children. The CPSS is usually administered to school children within school boundaries, or in an off-site location to assess symptoms of trauma. Some, but not all, people experience symptoms after a traumatic event, and in serious cases, these people may not get better on their own. Early and accurate identification, especially in children, of experiencing distress following a trauma could help with early interventions. The CPSS is one of a handful of promising measures that has accrued good evidence for reliability and validity, along with low cost, giving it good clinical utility as it addresses a public health need for better and larger scale assessment.

The Attribution Questionnaire (AQ) is a 27-item self-report assessment tool designed to measure public stigma towards people with mental illnesses. It assesses emotional reaction and discriminatory responses based on answers to a hypothetical vignette about a man with schizophrenia named Harry. There are several different versions of the vignette that test multiple forms of attribution. Responses assessing stigma towards Harry are in the form of 27 items rated on a Likert scale ranging from 1 (not at all) to 9 (very much). There are 9 subscales within the AQ that breakdown the responses one could have towards a person with mental illness into different categories. The AQ was created in 2003 by Dr. Patrick Corrigan and colleagues and has since been revised into smaller tests because of the complexity and hypothetical that did not capture children and adolescent's stigmas well. The later scales are the Attribution Questionnaire-9 (AQ-9), the revised Attribution Questionnaire (r-AQ), and the children's Attribution Questionnaire (AQ-8-C).
