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.

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.

Social phobia adalah ketakutan seseorang ketika beraktivitas di depan orang lain, seperti makan, minum, gemetar, memerah, berbicara, menulis atau muntah. Aktivitas ini merujuk kepada kecemasan dalam diri seseorang. Terdapat dua aspek yang dapat digunakan untuk mengidentifikasi kecemasan yaitu performance dan social. Penelitian ini bertujuan untuk menguji validasi alat ukur Liebowitz Social Anxiety Scale (LSAS). Penelitian ini merupakan penelitian kuantitatif dengan kriteria subjek mahasiswa aktif strata 1 usia 17-25 tahun. Subjek penelitian berjumlah 177 mahasiswa dari berbagai perguruan tinggi di Indonesia. Data diperoleh melalui google form yang disebarkan secara online dan data diolah menggunakan aplikasi SPSS. Teknik sampling yang digunakan adalah accidental sampling sehingga subjek yang dibutuhkan adalah subjek yang memenuhi kriteria di atas. Validasi alat ukur pada penelitian ini menggunakan sumber bukti berdasarkan struktur internal dan korelasi dengan alat ukur lain (Beck Depression Inventory dan Social Interaction Anxiety Scale). Hasil yang diperoleh dari penelitian ini membuktikan bahwa alat ukur LSAS valid dan dapat digunakan untuk mengukur kecemasan sosial.

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.

The present study aimed at establishing the Turkish version of the Liebowitz Social Anxiety Scale. For this aim interrater, test-retest, and internal reliability coefficients of the Turkish version were assessed as well as its convergent, discriminant, and criterion validity. Subjects were 88 patients with the diagnosis of generalized social phobia, 40 patients with a diagnosis of anxiety disorders other than generalized social phobia, and 40 people had no diagnosis of psychopathology. All reliability assessments indicated good reliability. For convergent and discriminant validity, correlations of 3 scores (2 subscales and the whole scale) and the Beck Anxiety Inventory were examined. Consistent with the expectations of the discriminant validity, correlations based on the whole sample were not significant. On the other hand, consistent with the expectations of the convergent validity, when patients with the diagnosis of generalized social phobia were considered, all the correlations were significant. Finally, the criterion validity of the Turkish version indicated that all 3 scores discriminated patients with the diagnosis of generalized social phobia, not only from the people who were free of psychopathology but also from the patients with the diagnosis of anxiety disorders other than generalized social phobia. Findings were discussed in the light of literature.
