    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.

    Um protocolo breve de modificações cognitivas e exposição gradal para redução de sintomas de medo de falar em público
    (Universidade Federal de São Paulo (UNIFESP), 1999) Kozasa, Elisa Harumi [UNIFESP]; Leite, José Roberto (UNIFESP)
    O presente estudo consiste na proposicao e teste de um protocolo breve que inclui exposicao e reestruturacao cognitiva em sujeitos que apresentam sintomas de medo de falar em publico. A amostra foi constituida principalmente de estudantes universitarios, considerando-se que esta populacao apresenta este sintoma de forma significativa. Apos o procedimento ter sido aplicado, foi realizado um follow-up de 15 meses. Os resultados sugerem uma melhora significante no auto-controle e no desempenho de falar em publico, nas situacoes de exposicao. Estes resultados levam-nos a supor que o protocolo breve usado neste experimento pode ser efetivo no alivio deste tipo de medo e representa vantagens evidentes quando comparado a metodos longos de treinamento ou tratamento

    Transtornos de ansiedade e exercício físico
    (Associação Brasileira de Psiquiatria - ABP, 2007-06-01) Araujo, Sônia Regina Cassiano de [UNIFESP]; Mello, Marco Tulio de [UNIFESP]; Leite, Jose Roberto [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)
    OBJECTIVE: Until the mid 90's, most of the studies on the anxiolytic effects of exercise were carried out through the evaluation of the anxiety state of young individuals. They were college students or athletes who might be considered pre-fit, thus limiting the validity of the conclusions as regards populations with pathological anxiety. The number of studies involving patients with anxiety disorder is increasing nowadays. Therefore, the objective of the study is to review the articles that discuss the influence of physical exercise on anxiety disorders. METHOD: We ran a MEDLINE search between 1966-1995 and 1996-2006 using the keywords anxiety, panic, phobic disorders, exercise, and physical fitness, in addition to the cross-reference of the articles selected and further analyses of bibliographical references on the topic. RESULTS: Our findings showed heterogeneous designs and methodological limitations. The latest publications are promising and point to the use of physical exercise as an aid to traditional therapies in the treatment of anxiety disorders. CONCLUSION: We observed that aerobic exercises below the lactate threshold might be the most adequate. However, they do not clarify the implications of anaerobic exercise, which suggests caution in the prescription of exercise, mainly the anaerobic kind, to individuals with pathologic anxiety.
