OBJECTIVE: Liebowitz Social Anxiety Scale is an instrument used to evaluate the severity of social phobia. It has been widely used in different contexts and cultures, presenting variable psychometric properties. The objective of this article is to investigate the internal consistency and the factor structure of this scale. METHOD: In a sample of 300 alcoholic patients hospitalized in 3 mental clinics in Southern Brazil, 74 of them were social phobics (24.6%). The Structured Clinical Interview for DSM-IV-Axis I Disorders - Patient Edition, a semi-structured clinical interview based on DSM-IV, was used to check for the diagnosis of social phobia. The internal consistency was measured by Cronbach's alpha. Data were subjected to a factor analysis with the principal component method of parameter estimation. Questionnaire items loading at 0.35 or above were considered in the final factor solution. RESULTS: The coefficient of internal consistency was 0.95. All items showed corrected item-total correlation coefficient above 0.15, considered the minimum requested index. The factor analysis resulted in 5 dimensions which corresponded to 52.9% of the total variance. The five factors extracted were: factor I - speaking in a group, factor II - activity in public, factor III - social interaction with unknown person, factor IV - attitude of disagreement or disapproval and factor V - social interaction in leisure activity. CONCLUSIONS: The scale proved to be reliable and structurally valid instrument for use in a population of alcoholic patients. The possibility of screening for social phobia through the use of the instrument may be helpful in identifying probable cases of the disorder among alcoholics.

Liebowitz Social Anxiety Scale

Zusammenfassung Ziel der Studie Bei der Untersuchung von sozialer Ängstlichkeit haben sich die Fragebögen Liebowitz Social Anxiety Scale (LSAS) und das Social Phobia-Inventory (SPIN) etabliert. Außerdem wird zum Screening sozialer Ängstlichkeit häufig die Subskala Unsicherheit im Sozialkontakt des Brief Symptom Inventory (BSI-53) eingesetzt. Alle drei Skalen geben vor dasselbe Konstrukt zu erfassen. Somit stellt sich die Frage der Konvergenz dieser Skalen. Um Forschungsergebnisse zu sozialer Ängstlichkeit, welche diese Instrumente nutzen, über einen fragebogenübergreifenden Faktor (Common-Faktor) vergleichbar zu machen, wird in der vorliegenden Studie ein Item Response Theorie (IRT) Linking Ansatz verwendet. Methodik 64 deutschsprachige psychiatrische Patienten und 295 Probanden aus der deutschen Normalbevölkerung füllten die drei Fragebögen aus. Verschiedene IRT-Modelle – darunter Graded Response Modelle (GRM) – wurden an die Daten angepasst und verglichen. Basierend auf dem Modell mit dem besten Fit wurden Regressionsanalysen durchgeführt. Der Common-Faktor wurde dabei jeweils von den Fragebogensummenwerten vorhergesagt. Ergebnisse Der Zusammenhang zwischen den verschiedenen Skalen wird am besten durch ein Bi-Faktor GRM erklärt (RMSEA=0,036; CFI=0,977; WRMR=1,061). Anhand der Ergebnisse der Regressionsanalysen lassen sich drei Gleichungen zur Transformation von Fragebogensummenwerten ableiten. Schlussfolgerung Durch den IRT Linking Ansatz konnte ein fragebogenübergreifender genereller Faktor Sozialer Ängstlichkeit abgeleitet werden. Gemeinsamkeiten und Unterschiede wurden dabei berücksichtigt. Dies hat sowohl für die Forschung als auch für die Praxis Vorteile. Eine Replikation dieser Studie sowie die Implementierung weiterer Instrumente wird empfohlen, um die Gültigkeit dieses Ansatzes zu überprüfen und die Ergebnisse zu generalisieren.

Introduction: Individuals with visible differences due to medical conditions, such as systemic sclerosis (SSc; scleroderma), have reported difficulty navigating social situations because of issues such as staring, invasive questions, and rude comments. Fears or anxiety linked to situations in which a person interacts with others is known as social interaction anxiety. However, there exists no validated measurement tool to examine social interaction anxiety in rheumatologic conditions. Methods: The present study examines the reliability (internal consistency) and validity (structural and convergent) of the Social Interaction Anxiety Scale-6 (SIAS-6) in a sample of 802 individuals with SSc, and compares these psychometric properties across limited and diffuse subtypes of the disease. Multi-group confirmatory factor analysis was used to examine the factor structure of the SIAS-6 in patients with both limited and diffuse SSc. Results: A one-factor structure was found to fit well for individuals with SSc with both limited and diffuse disease. The measure demonstrated strong internal consistency reliability and convergent validity with relevant measures in expected magnitudes and directions. Conclusions: The SIAS-6 is a psychometrically robust measure that can confidently be used in SSc populations to examine social interaction anxiety. Moreover, scores can meaningfully be compared between patients with limited and diffuse disease.

Liebowitz Social Anxiety Scale

AbstractObjectiveSocial anxiety is a common problem in psychotic disorders. The Liebowitz Social Anxiety Scale, Self-Rating version (LSAS-SR) is a widely used instrument to capture different aspects of social anxiety, but its psychometric properties have not been tested in this patient group. The aims of the present study were to evaluate the psychometric properties of the LSAS-SR in patients with first episode psychosis, to investigate whether it differentiated between active and passive social withdrawal and to test which clinical factors contributed to current level of social anxiety.MethodA total of 144 first episode psychosis patients from the ongoing Thematically Organized Psychosis (TOP) study were included at the time of first treatment. Diagnoses were set according to the Structured Clinical Interview (SCID-1) for DSM-IV. A factor analysis was carried out and the relationship of social anxiety to psychotic and general symptomatology measured by the Positive and Negative Syndrome Scale (PANSS) was evaluated. Possible contributors to social anxiety were analyzed using multiple hierarchic regression analysis.ResultsThe factor analysis identified three subscales: public performance, social interaction and observation. All three subscales showed satisfactory psychometric properties, acceptable convergent and discriminate properties, and confirmed previous findings in social anxiety samples. Self-esteem explained a significant amount of the variance in social anxiety, even after adjusting for the effects of delusions, suspiciousness and depression.ConclusionThe study shows that the LSAS-SR can be used in this patient group, that social anxiety is strongly related to both behavioral social avoidance and to self-esteem. The results support the use of this measure in assessment of social anxiety in both clinical settings and in research.

Treatment Sensitivity

Background. The present study provides data on the reliability, validity and treatment sensitivity of the Liebowitz Social Anxiety Scale (LSAS), one of the most commonly used clinician-administered scales for the assessment of social phobia.Method. Three hundred and eighty-two patients from several studies of the treatment of social phobia were evaluated. An independent assessor administered the LSAS to each patient prior to the initiation of treatment. Patients also completed other measures of social anxiety and avoidance, although the specific measures varied across samples.Results. The LSAS and its subscales were normally distributed and demonstrated excellent internal consistency. The convergent validity of the LSAS was demonstrated via significant correlations with other commonly-used measures of social anxiety and avoidance. These correlations also tended to be larger than correlations with measures of depression, especially after treatment. However, the pattern of correlations of LSAS subscales with one another and with the other measures suggest that the fear subscales and the avoidance subscales may not be sufficiently distinct in clinical samples. The LSAS was also demonstrated to be sensitive to the effects of pharmacological treatments of social phobia over time and in comparison to double-blind pill placebo.Conclusion. The LSAS appears to be a reliable, valid and treatment sensitive measure of social phobia. Further study of the LSAS, both in samples with severe social phobia and in community samples, is needed.

Liebowitz Social Anxiety Scale

Abstract. The Liebowitz Social Anxiety Scale for Children and Adolescents (LSAS-CA) is a valid and reliable clinician-administered measure of social anxiety symptoms in young people. It has been adapted for self-report completion, and although the psychometric properties of this version of the scale have been examined in Spanish, Hebrew, and French language versions, this has not yet been done for the English language version. In the present study, we examined the factor structure and psychometric properties of the self-report version of the scale (LSAS-CA-SR) in a sample of UK adolescents recruited from schools. The factor structure of the scale was determined in our sample of N = 829; a four-factor structure, with interaction anxiety, interaction avoidance, performance anxiety, and performance-avoidance subscales, provided the best fit to the data. Measurement invariance of the scale was demonstrated across age and gender. Psychometric properties of the scale were sound, with good internal consistency (.88–.97), acceptable test-retest reliability (.45–.57), and evidence for convergent and divergent validity.
