Validation of the Subjective Handicap of Epilepsy (SHE) in Brazilian patients with epilepsy

The objectives of the study were to translate and adapt the Subjective Handicap of Epilepsy (SHE) instrument to Brazilian Portuguese and to determine its psychometric properties for the evaluation of quality of life in patients with epilepsy. A sample of 448 adult patients with epilepsy with different clinical profiles (investigation, preoperative period, postoperative period, and drug treatment follow-up) was evaluated with the SHE and the Epilepsy Surgery Inventory (ESI-55). Exploratory factorial analysis demonstrated that four factors explained 60.47% of the variance and were sensitive to discriminate the different clinical groups, with the preoperative group having the poorest quality of life. Internal consistency ranged from 0.92 to 0.96, and concurrent validity with the ESI-55 was moderate/strong (0.32-0.70). Test-retest reliability was confirmed, with an ICC value of 0.54 (2 days), 0.91 (7 days), and 0.97 (30 days). The SHE had satisfactory psychometric qualities for use in the Brazilian population, similar to those of the original version. The instrument seems to be more adequate in psychometric terms for the postoperative and drug treatment follow-up groups, and its use should be encouraged. (c) 2012 Elsevier Inc. All rights reserved

The Fourteenth Data Release of the Sloan Digital Sky Survey: First Spectroscopic Data from the extended Baryon Oscillation Spectroscopic Survey and from the second phase of the Apache Point Observatory Galactic Evolution Experiment

The fourth generation of the Sloan Digital Sky Survey (SDSS-IV) has been in operation since July 2014. This paper describes the second data release from this phase, and the fourteenth from SDSS overall (making this, Data Release Fourteen or DR14). This release makes public data taken by SDSS-IV in its first two years of operation (July 2014-2016). Like all previous SDSS releases, DR14 is cumulative, including the most recent reductions and calibrations of all data taken by SDSS since the first phase began operations in 2000. New in DR14 is the first public release of data from the extended Baryon Oscillation Spectroscopic Survey (eBOSS); the first data from the second phase of the Apache Point Observatory (APO) Galactic Evolution Experiment (APOGEE-2), including stellar parameter estimates from an innovative data driven machine learning algorithm known as "The Cannon"; and almost twice as many data cubes from the Mapping Nearby Galaxies at APO (MaNGA) survey as were in the previous release (N = 2812 in total). This paper describes the location and format of the publicly available data from SDSS-IV surveys. We provide references to the important technical papers describing how these data have been taken (both targeting and observation details) and processed for scientific use. The SDSS website (www.sdss.org) has been updated for this release, and provides links to data downloads, as well as tutorials and examples of data use. SDSS-IV is planning to continue to collect astronomical data until 2020, and will be followed by SDSS-V.Comment: SDSS-IV collaboration alphabetical author data release paper.

Social Anxiety Disorder: validation of assessment instruments.

O Transtorno de Ansiedade Social (TAS) é um distúrbio de início precoce, com prevalência e comorbidades significativas, favorecendo prejuízos importantes no funcionamento laboral, familiar, social e acadêmico, especialmente em pessoas jovens. Dada tais características, faz-se necessária a identificação precoce e o diagnóstico preciso do TAS, o que requer instrumentos validados. Objetivou-se a avaliação sistemática do TAS, por meio de um conjunto de instrumentos validados quanto às suas qualidades psicométricas de fidedignidade e validade, em uma população de adultos jovens brasileiros, estudantes universitários, sob a perspectiva da auto e hetero-avaliação. Para tal, realizou-se a validação transcultural dos instrumentos auto-avaliativos: Social Phobia Inventory (SPIN) e Self Statements During Public Speaking Scale (SSPS versão traço e estado) e do instrumento hetero-avaliativo Brief Social Phobia Scale (BSPS), com aprovação prévia dos autores das versões originais. O delineamento metodológico envolveu três etapas. Na primeira, a amostra utilizada para avaliação dos instrumentos SPIN e SSPS foi composta por 2314 estudantes universitários da população geral. Na segunda etapa, para a validação dos instrumentos SPIN, SSPS e BSPS, utilizou-se de uma amostra de 178 estudantes universitários identificados como casos (N = 88) e não-casos (N = 90) de TAS, através da Entrevista Clínica Estruturada para o DSM-IV (SCID-IV). Na terceira etapa, 45 estudantes universitários também classificados como casos (N = 24) e não-casos (N = 21) de TAS compuseram a amostra para validação da SSPS-estado no contexto de um modelo experimental de falar em público. O SPIN apresentou boa consistência interna (=0,63- 0,90), validade concorrente com o Inventário de Ansiedade de Beck (BAI) (r = 0,10-0,63) e SSPS-traço (r = 0,22-0,65), validade discriminativa (sensibilidade = 0,84, especificidade = 0,87) e validade de construto. A análise fatorial indicou a presença de um número variável de fatores em função da amostra estudada. Destaca-se a versão reduzida deste instrumento, o Mini-SPIN, que também apresentou ótimos indicadores psicométricos (sensibilidade = 0,77, especificidade = 0,67). A SSPS-traço mostrou-se bastante adequada quanto à consistência interna ( = 0,64-0,94), validade concorrente com o BAI (r = 0,18-0,53) e SPIN (r = 0,22-0,65) e validade discriminativa entre casos e não-casos de TAS. A análise fatorial evidenciou a presença de dois fatores: auto-avaliação positiva e negativa. A BSPS aplicada com o suporte de um roteiro de perguntas-guia, apresentou excelentes confiabilidade inter-avaliadores (0,86-1,00) e validade discriminativa (sensibilidade = 0,84, especificidade = 0,83); adequadas consistência interna ( = 0,48-0,88), validade concorrente com o BAI (r = 0,21-0,62), SPIN (r = 0,24-0,82) e SSPS-traço (r = 0,23-0,31) e validade de construto. A análise fatorial apontou a presença de seis fatores que explicam 71,8% da variância dos dados. A SSPS-estado mostrou-se apropriada para avaliação dos aspectos cognitivos associados ao falar em público no contexto de um modelo experimental de simulação de falar em público, apresentando excelente validade discriminativa entre casos e não-casos de TAS, além de sensibilidade para discriminar os diferentes níveis de ansiedade nas fases do procedimento. Todos os instrumentos mostraram boas qualidades psicométricas, o que recomenda o uso na população de universitários brasileiros, podendo ser aplicados tanto em contextos experimentais como clínicos, favorecendo a detecção mais precisa do TAS, especialmente nos contextos de atenção primária à saúde.Social Anxiety Disorder (SAD) is a condition of early onset and of significant prevalence and comorbidity, greatly impairing the functioning of young people in terms of job, family, social life and academic performance. In view of these characteristics, an early identification and precise diagnosis of SAD are necessary, requiring validated instruments. The objective of the present study was to perform a systematic evaluation of SAD by means of a set of instruments tested in a population of young Brazilian adults, college students, from the perspective of self- and hetero-evaluation. For this purpose, transcultural validation was performed of the self-evaluation instruments Social Phobia Inventory (SPIN) and Self Statements During Public Speaking Scale (SSPS trait and state version) and of the hetero-evaluation instrument Brief Social Phobia Scale (BSPS), after approval by the authors of the original versions. The methodological design involved three stages. In the first, the sample used for evaluation of the SPIN and SSPS instruments consisted of 2314 college students from the general population. In the second stage, a sample of 178 college students identified as cases (N = 88) and non-cases (N = 90) of SAD, confirmed by the Structured Clinical Interview for DSM-IV (SCID-IV) was used for the evaluation of the SPIN, SSPS and BSPS instruments. In the third stage, 45 college students, also classified as cases (N = 24) and non-cases (N = 21) of SAD, formed the sample for the evaluation of the SSPS-state within the context of an experimental public speaking model. SPIN presented good internal consistency ( = 0,63-0,90), validity in agreement with the Beck Anxiety Inventory (BAI) (r = 0,10-0,63) and SSPS-trait (r = 0,22-0,65), discriminative validity (sensitivity = 0,84, specificity = 0,87) and construct validity. Factorial analysis indicated the presence of a variable number of factors as a function of the sample studied. The reduced version of this instrument, the Mini-SPIN, is emphasized, also presenting excellent psychometric indicators (sensitivity = 0,77, specificity = 0,67). SSPS-trait proved to be quite adequate regarding internal consistency ( = 0,64-0,94), validity in agreement with the BAI (r = 0,18-0,53) and SPIN (r = 0,22-0,65), and discriminative validity between cases and non-cases of SAD. Factorial analysis demonstrated the presence of two factors, i.e., positive and negative self-evaluation. The BSPS applied with the support of a guidingquestion list, presented excellent inter-rater reliability (0,86-1,00) and discriminative validity (sensitivity = 0,84, specificity = 0,83), adequate internal consistency ( = 0,48- 0,88), validity in agreement with the BAI (r = 0,21-0,62), SPIN (r = 0,24-0,82) and SSPStrait (r = 0,23-0,31), and construct validity. Factorial analysis indicated the presence of six factors that explained 71,8% of the variance of the data. The SSPS-state proved to be appropriate for the evaluation of cognitive aspects associated with public speaking, presenting excellent discriminative validity between cases and non-cases of SAD, as well as sensitivity in the discrimination of the different levels of anxiety during the phases of the procedure. All instruments showed good psychometric qualities, a fact that recommends their use in the population of Brazilian college students, with the possibility of application both in the clinical and experimental context, favoring a more precise detection of SAD, especially within the context of primary health care

Further psychometric study of the Beck Anxiety Inventory including factorial analysis and social anxiety disorder screening

Objective. To analyze the psychometric properties of the Brazilian Portuguese version of the Beck Anxiety Inventory (BAI) in terms of its internal consistency, scores distribution, concurrent and discriminant validity, and factorial analysis in a sample of university students and social anxiety disorder (SAD) cases and non-cases. Methods. A sample of Brazilian university students from the general population (N = 2314) and a sample of university students identified as cases (N = 88) and non-cases (N = 90) of SAD were assessed, using as a parameter the Structured Clinical Interview for the DSM-IV. The different instruments were completed individually in the presence of an experienced rater. Results. The BAI showed adequate internal consistency (0.88-0.92) and discriminant validity, with 0.74 sensitivity and 0.71 specificity for a cut-off score of 10. The factorial analysis suggested a three-factor solution to be the most adequate. Conclusions. The version of the BAI studied is quite adequate to be used in the context of Brazilian university students, identifying the presence of anxiety indicators. However, its usefulness to screen for SAD seems limited

Further Study of the Psychometric Qualities of a Brief Screening Tool for Social Phobia (MINI-SPIN) Applied to Clinical and Nonclinical Samples

PURPOSE. The purpose of this study was to further assess the psychometric qualities of the Mini-Social Phobia Inventory (MS) to screen for social anxiety disorder (SAD). DESIGN AND METHODS. The MS and other self- and clinician-rated scales for anxiety and social anxiety were applied in 2,314 university students and in samples of SAD patients (n = 88) and nonpatients (n = 90). FINDINGS. The MS revealed adequate discriminative validity, internal consistency (alpha = 0.49-0.73), convergent validity with the Social Phobia Inventory, Brief Social Phobia Scale, and Self-Statements During Public Speaking Scale and convergent and divergent validity with the Beck Anxiety Inventory. PRACTICE IMPLICATIONS. The MS has shown to be a fast and efficient screening instrument for SAD in different cultures and contexts.FAEPAConselho Nacional de Desenvolvimento Cientifico e Tecnologico (CNPq, Brazil

Social anxiety disorder: studies of instrument validation for the Brazilian context

Social anxiety disorder (SAD) is a highly prevalent condition even though its recognition and diagnosis are underestimated by both patients and clinicians. In view of the importance of assessment scales for systematic diagnosis in psychiatry, the objective of this investigation was to present studies of validation for the Brazilian population of three instruments for the assessment of different aspects of SAD. The following psychometric studies were carried out: a) discriminative validity of the Mini Social Phobia Inventory (Mini-SPIN-MS), a reduced instrument for the screening of SAD; b) reliability and discriminative validity of the Brief Social Phobia Scale (BSPS), a hetero-applied instrument for the assessment of different aspects of SAD, and c) discriminative validity of the items and subscales of the Self-Statements during Public Speaking Scale (SSPS), an instrument for the assessment of cognitive aspects related to public speaking. All instruments showed excellent psychometric qualities, especially indicators of discrimination between persons with and without SAD, with diagnostic confirmation by the Structured Clinical Interview for DSM-IV (SCID-IV). It was concluded that this set of instruments, with specificity regarding their objectives, could be of great clinical usefulness, especially for the Brazilian population that, until recently, had no such resources for the measurement and assessment of the different aspects of SAD. New multicenter and intercultural studies may provide further information about cultural influences on SAD

Study of the Discriminative Validity of the PHQ-9 and PHQ-2 in a Sample of Brazilian Women in the Context of Primary Health Care

PURPOSE. This study aimed to assess the discriminative validity of the Brazilian version of the Patient Health Questionnaire (PHQ-9) and of its reduced version (PHQ-2). DESIGN AND METHODS. The sample consisted of 177 women (60 cases of depression and 117 noncases). The SCID-IV was used as the gold standard. FINDINGS. For the PHQ-9, a cutoff score equal to or higher than 10 proved to be the most adequate for the screening of depression, whereas the best cutoff score for the PHQ-2 was found to lie between 3 and 4. PRACTICE IMPLICATIONS. The systematic use of these instruments in nursing and in the context of primary health care could favor the early detection of depression.Fundacao de Apoio ao Ensino (FAEPA)Pesquisa e Assistencia do Hospital das Clinicas da Faculdade de Medicina de Ribeirao Preto da Universidade de Sao Paulo (FAEPA)Conselho Nacional de Desenvolvimento Cientifico e Tecnologico (CNPq, Brazi
