Impact of alcohol intoxication and withdrawal syndrome on social phobia and panic disorder in alcoholic inpatients

PURPOSE: To investigate the impact of alcohol intoxication and withdrawal on the course of social phobia and panic disorder. METHOD: A group of 41 alcoholic inpatients undergoing detoxification therapy were interviewed using the SCID-I (DSM-IV) and questions to detect fluctuations in the course of social phobia and panic disorder as a function of the different phases in alcohol dependence (intoxication, withdrawal, and lucid interval). RESULTS: Only 1 (2.4%) patient presented panic disorder throughout life, and 9 (21.9%) had panic attacks during alcohol intoxication or during the withdrawal syndrome. Sixteen (39%) alcoholic patients showed social phobia with onset prior to drug use. However, drinking eventually became unable to alleviate social phobia symptoms or worsened such symptoms in 31.2% of social-phobic patients. While patients with social phobia reported a significant improvement in psychiatric symptoms during alcohol intoxication, patients experiencing panic attacks worsened significantly during intoxication. In the withdrawal phase, patients with social phobia tended to have more and more intense phobic symptoms. CONCLUSION: Our findings indicate that the impact of alcohol intoxication is different for social phobia as compared to panic disorder, at first decreasing the social-phobic symptoms but later aggravating them. In panic disorder, the impact of intoxication by alcohol is more harmful, at least in the short term.

The Portuguese language version of social phobia and Anxiety Inventory: analysis of items and internal consistency in a Brazilian sample of 1,014 undergraduate students

OBJECTIVE: Theoretical and empirical analysis of items and internal consistency of the Portuguese-language version of Social Phobia and Anxiety Inventory (SPAI-Portuguese). METHODS: Social phobia experts conducted a 45-item content analysis of the SPAI-Portuguese administered to a sample of 1,014 university students. Item discrimination was evaluated by Student's t test; interitem, mean and item-to-total correlations, by Pearson coefficient; reliability was estimated by Cronbach's alpha. RESULTS: There was 100% agreement among experts concerning the 45 items. On the SPAI-Portuguese 43 items were discriminative (p < 0.05). A few inter-item correlations between both subscales were below 0.2. The mean inter-item correlations were: 0.41 on social phobia subscale; 0.32 on agoraphobia subscale and 0.32 on the SPAI-Portuguese. Item-to-total correlations were all higher then 0.3 (p < 0.001). Cronbach's alphas were: 0.95 on the SPAI-Portuguese; 0.96 on social phobia subscale; 0.85 on agoraphobia subscale. CONCLUSION: The 45-item content analysis revealed appropriateness concerning the underlying construct of the SPAI-Portuguese (social phobia, agoraphobia) with good discriminative capacity on 43 items. The mean inter-item correlations and reliability coefficients demonstrated the SPAI-Portuguese and subscales internal consistency and multidimensionality. No item was suppressed in the SPAI-Portuguese but the authors suggest that a shortened SPAI, in its different versions, could be an even more useful tool for research settings in social phobia.

Is avoidant disorder part of the social phobia spectrum in a referred sample of Brazilian children and adolescents?

The diagnosis of avoidant disorder was deleted from the Diagnostic and Statistical Manual of Mental disorders - fourth edition (DSM-IV) based on a `committee decision' suggesting that avoidant disorder is part of the social phobia spectrum. The objective of the present study was to examine the nature of this clinical association in a referred sample of Brazilian children and adolescents. We assessed a referred sample of 375 youths using semi-structured diagnostic interview methodology. Demographic (age at admission to the study and sex) and clinical (level of impairment, age at onset of symptoms and pattern of comorbidity) data were assessed in subsamples of children with avoidant disorder (N = 7), social phobia (N = 26), and comorbidity between both disorders (N = 24). Although a significant difference in the male/female ratio was detected among groups (P = 0.03), none of the other clinical variables differed significantly among subjects that presented each condition separately or in combination. Most of the children with avoidant disorder fulfilled criteria for social phobia. Thus, our findings support the validity of the conceptualization of avoidant disorder as part of the social phobia spectrum in a clinical sample.

Validation of the Social Phobia and Anxiety Inventory for Children (SPAI-C) in a sample of Brazilian children

The purpose of the present study was to examine the factor structure and psychometric properties of the Social Phobia and Anxiety Inventory for Children (SPAI-C), an instrument developed in the United States and applied to a sample of Brazilian schoolchildren. The process included the translation of the original material from English into Portuguese by two bilingual psychiatrists and a back translation by a bilingual physician. Both the front and back translations were revised by a bilingual child psychiatrist. The study was performed using a cross-sectional design and the Portuguese version of the SPAI-C was applied to a sample of 1954 children enrolled in 3rd to 8th grade attending 2 private and 11 public schools. Eighty-one subjects were excluded due to an incomplete questionnaire and 2 children refused to participate. The final sample consisted of 1871 children, 938 girls (50.1%) and 933 boys (49.8%), ranging in age from 9 to 14 years. The majority of the students were Caucasian (89.0%) and the remainder were African-Brazilian (11.0%). The Pearson product-moment correlation showed that the two-week test-retest reliability coefficient was r = 0.780 and Cronbach's alpha was 0.946. The factor structure was almost similar to that reported in previous studies. The results regarding the internal consistency, the test-retest reliability and the factor structure were similar to the findings obtained in studies performed on English speaking children. The present study showed that the Portuguese language version of SPAI-C is a reliable and valid measure of social anxiety for Brazilian children.

Validação da versão brasileira do questionário de ansiedade cardíaca

FUNDAMENTOS: A ansiedade cardíaca (AC) é o medo de sensações cardíacas, caracterizado por sintomas recorrentes de ansiedade em pacientes com ou sem doença cardiovascular. O Questionário de Ansiedade Cardíaca (QAC) é uma ferramenta para avaliar a AC, já adaptado, mas não validado em português. OBJETIVO: Este trabalho apresenta as três fases dos estudos de validação do QAC brasileiro. MÉTODOS: Foram recrutados 98 pacientes com doença arterial coronária, a fim de extrair a estrutura fatorial e avaliar a confiabilidade do QAC (fase 1). O objetivo da fase 2 foi explorar a validade convergente e divergente. Cinquenta e seis pacientes completaram o QAC, juntamente com o Escala de sensações corporais (ESC) e o Versão brasileira do Social Phobia Inventory (SPIN). Para determinar a validade discriminante (fase 3), comparamos os escores do QAC de dois subgrupos formados por pacientes da fase 1 (n = 98), de acordo com os diagnósticos de transtorno do pânico e agorafobia obtidos com o MINI - Mini International Neuropsychiatric Interview (Mini Entrevista Neuropsiquiátrica Internacional). RESULTADOS: A solução de dois fatores foi a mais interpretável (46,4% da variância). As subescalas foram denominadas de "Medo e Hipervigilância" (n = 9; alfa = 0,88) e "Evitação" (n = 5; alfa = 0,82). Foi encontrada correlação significativa do fator 1 com o escore total do ESC (p < 0,01), mas não com o fator 2. Os fatores do SPIN apresentaram correlações significativas com as subescalas do QAC (p < 0,01). Na fase 3, os escores dos pacientes "Cardíacos com pânico" foram significativamente maiores no fator 1 do QAC (t = -3,42; p < 0,01, IC = -1,02 a -0,27), e maiores, mas não significativamente diferentes, no fator 2 (t = -1,98; p = 0,51, IC = -0.87 a 0,00). CONCLUSÕES: Os presentes resultados fornecem uma versão final brasileira validada do QAC adequada aos contextos clínicos e de pesquisa.

Pharmacology of human experimental anxiety

This review covers the effect of drugs affecting anxiety using four psychological procedures for inducing experimental anxiety applied to healthy volunteers and patients with anxiety disorders. The first is aversive conditioning of the skin conductance responses to tones. The second is simulated public speaking, which consists of speaking in front of a video camera, with anxiety being measured with psychometric scales. The third is the Stroop Color-Word test, in which words naming colors are painted in the same or in a different shade, the incongruence generating a cognitive conflict. The last test is a human version of a thoroughly studied animal model of anxiety, fear-potentiated startle, in which the eye-blink reflex to a loud noise is recorded. The evidence reviewed led to the conclusion that the aversive conditioning and potentiated startle tests are based on classical conditioning of anticipatory anxiety. Their sensitivity to benzodiazepine anxiolytics suggests that these models generate an emotional state related to generalized anxiety disorder. On the other hand, the increase in anxiety determined by simulated public speaking is resistant to benzodiazepines and sensitive to drugs affecting serotonergic neurotransmission. This pharmacological profile, together with epidemiological evidence indicating its widespread prevalence, suggests that the emotional state generated by public speaking represents a species-specific response that may be related to social phobia and panic disorder. Because of scant pharmacological data, the status of the Stroop Color-Word test remains uncertain. In spite of ethical and economic constraints, human experimental anxiety constitutes a valuable tool for the study of the pathophysiology of anxiety disorders.
