Development and psychometric properties of the Cognitive Distortions Questionnaire for Adolescents (CD-Quest-T).

INTRODUCTION: The Cognitive Distortions Questionnaire (CD-Quest) is an instrument that identifies logical errors or cognitive distortions and is used in trial-based cognitive therapy (TBCT). However, it had previously only been available for adults. OBJECTIVES: To develop and validate a version of the CD-Quest for teens (CD-Quest-T) aged 11 to 17 years and test its psychometric properties. METHOD: A total of 299 schoolchildren participated in the investigation. After content validity was assessed, the language was adapted for the target age group, and the length of the instrument was reduced to eight items (from the initial 15). Five cognitive therapists analyzed the content and structure of the items. Finally, to investigate the construct validity of the CD-Quest-T, the instrument was divided into a full scale and two subscales, which measure the frequency of the distortions and the intensity attributed to them, respectively. RESULTS: The overall internal consistency of the scale was α = 0.77, whereas subscale indices were α = 0.75 for the frequency scale and α = 0.73 for the intensity scale. Results from exploratory factor analysis and concurrent validity analysis indicated that the CD-Quest-T items have good psychometric properties and generate scores reliably. CONCLUSION: The psychometric properties of the CD-Quest-T demonstrate its adequacy for measurement of cognitive distortions in adolescents.

Family Aggression Screening Tool (FAST): Factor structure and psychometric properties of subscales.

BACKGROUND: The Family Aggression Screening Tool (FAST) is an instrument to screen for experiences of maltreatment using primarily pictorial representations, including direct victimisation and exposure to intimate partner violence. The initial psychometric properties of the FAST were reported in the original research in the United Kingdom. OBJECTIVE: This research aimed to replicate and to extend the evaluation of the psychometric properties of FAST in Brazil. PARTICIPANTS AND SETTING: Data consisted of 648 youth aged 11 to 17 years from public schools in Brazil. METHOD: We employed confirmatory factor analysis (CFA), exploratory factor analysis (EFA) and exploratory graphical analysis (EGA). Concurrent validity was supported by strong correlations between the FAST's emotional and physical victimisation subscales and Childhood Trauma Questionnaire (CTQ) emotional and physical abuse subscales. RESULTS: CFA resulted in a solution including second and first order factors, resembling the original structure. FAST's reliability was assessed both through internal consistency and test-retest, showing favorable coefficients. CONCLUSION: Our results suggest that FAST has good psychometric properties for the Brazilian population with respect to both its validity and reliability.

A versão brasileira do Three-Dimensional Work Fatigue Inventory (3D-WFI): adaptação e propriedades psicométricas / The Brazilian version of the Three-Dimensional Work Fatigue Inventory (3D-WFI): adaptation and psychometric properties / La versión brasileña del Three-Dimensional Work Fatigue Inventory (3D-WFI): adaptación y propiedades psicométricas

Fadiga no trabalho é a percepção individual de desconforto físico, cognitivo e emocional, associada com sentimentos de perda de energia, cansaço e exaustão, levando a efeitos deletérios no desempenho laboral. O objetivo do presente trabalho foi adaptar e levantar evidências psicométricas para o contexto brasileiro do Three-Dimensional Work Fatigue Inventory (3D-WFI). O estudo foi conduzido com 455 trabalhadores adultos, oriundos de três contextos ocupacionais (segurança pública, saúde e população geral). Entre estes 251 eram do sexo masculino. Os dados analisados a partir de procedimentos fatoriais confirmatórios e multigrupo apontaram adequação ao modelo original de três dimensões de fadiga (física, cognitiva e emocional). Indicadores de precisão foram bons e superiores a 0,91 em todas as dimensões resultantes. Evidências externas do 3D-WFI foram observadas com engajamento no trabalho, satisfação com a vida e conflito trabalho-família. Discutem-se aplicações do instrumento para o contexto de pesquisa e diagnóstico nas organizações.

Work fatigue is the individual's perception of physical, cognitive, and emotional discomfort, associated with feelings of energy loss, tiredness, and exhaustion, leading to deleterious effects on work performance. This study aimed to adapt and raise psychometric evidence for the Brazilian context of the Three-Dimensional Work Fatigue Inventory (3D-WFI). The study was conducted with 455 adult workers from three occupational contexts (public safety, health, and general population). Among these, 251 were male. The data analyzed using confirmatory factorial and multigroup procedures indicated the original three-dimensional fatigue model (physical, cognitive and emotional). Accuracy indicators were good and above 0.91 in all resulting dimensions. External evidence of 3D-WFI was observed with work engagement, life satisfaction, and work-family conflict. Applications of the instrument for the context of research and diagnosis in organizations are discussed.

Chronic effect of vagotomy in the morphometry of the myenteric plexus of rats' duodenum / Efeito crônico da vagotomia sobre a morfometria do plexo mioentérico do duodeno de ratos

BACKGROUND: The gastrointestinal disorders have been associated with morphological alterations in the myenteric nervous plexus. AIM: To evaluate, through morphometric studies, the chronic effects of the subdiaphragmatic trunk vagotomy on the nervous plexus. METHODS: Fifteen male exemplars of Wistar Rattus novergicus weighing about 150g, distributed into three groups, have been used: control (n=5), Sham (n=5) and vagotomized (n=5). The animals were sacrificed after 30 and 90 days post surgery. Fragments of duodenum were fixed in Bouin solution, embedded into paraffin and stained with HE and PAS. Morphometric analysis was performed by a Carl Zeiss KM 450 image system. The following aspects were observed: the density of nervous cells per linear micrometer (µm) (ND); the area of perikarya (µm²) (NA); the number of satellite cells per µm (SCD); and the number of satellite cells per neuron (SC/N). The averages were compared with the help of "software" program Sigma Plus through two way - ANOVA and Tuckey post-test. RESULTS: Denervation increased SC/N (p<0,05) and NA (p<0,05), in a time-dependent denervation way (p<0,05). However ND and SCD, decreased, which significantly with the animal's age (p<0,001). CONCLUSION: Vagotomy altered the myenteric plexus morphology in a time-dependent way.

RACIONAL: As disfunções gastrintestinais têm sido associadas à alterações morfológicas no plexo nervoso mioentérico. OBJETIVO: Avaliar através do estudo morfométrico, os efeitos crônicos da vagotomia troncular subdiafragmática sobre esse plexo nervoso. MÉTODOS: Foram utilizados 15 exemplares machos de Rattus novergicus da variedade Wistar, com cerca de 150 g, distribuídos nos grupos controle (n=5), Sham (n=5) e vagotomizados (n=5). Os animais foram sacrificados depois de 30 e 90 dias após as operações. Em seguida, fragmentos do duodeno foram fixados em solução de Bouin, incluídos em parafina e corados por HE e PAS. A análise morfométrica foi realizada por meio do sistema de análise de imagem Carl Zeiss KM 450. Foram observados: a densidade de células nervosas por micrômetro linear (µm); a área dos pericários (µm²); o número de células satélites por µm; e o número de células satélites por neurônio. As médias foram comparadas com o auxílio do programa de "software" Sigma Plus através do Two way - ANOVA e do pós-teste de Tukey. RESULTADOS: A desnervação aumentou o número de células satélites por neurônios (p<0,05) e a área média dos pericários (p<0,05), de maneira dependente do tempo de desnervação (p<0,05), mas diminuiu significativamente a densidade de neurônios (p<0,05) e de células satélites (p<0,05) em função da idade (p<0,001). CONCLUSÃO: A vagotomia alterou a morfologia do plexo mioentérico de maneira dependente do tempo.

Pesquisa de bacilos álcool – ácido – resistentes em cortes histológicos de lesões sugestivas de tuberculose em bovinos / Search bacilli - acid - resistant in histological lesions suggestive of tuberculosis at bovines

Verificou-se a ocorrência de bacilos álcool-ácido resistentes, em linfonodos de bovinos com lesões sugestivas de tuberculose observadas durante inspeção sanitária em abatedouros-frigoríficos sob Serviço de Inspeção Federal (SIF), em Mato Grosso do Sul no período de maio a novembro de 2003. Foram colhidas 63 amostras que, depois de fixadas, foram destinadas à histopatologia e processadas pela técnica rotineira de inclusão em parafina. Á histopatologia, 74,6 por cento dos casos evidenciaram lesões granulomatosas características de tuberculose ganglionar, 17,5por cento apresentaram lesões nodulares inespecíficas e 7,9 por cento inconclusivos, apresentando-se como processos inflamatórios difusos. Bacilos álcool-ácido-resistentes foram observados em 70 por cento das lâminas coradas pela técnica de Ziehl Neelsen-Faraco.

Diagnóstico sorológico da brucelose bovina em animais adultos vacinados com dose reduzida da cepa 19 de Brucella abortus / Serological diagnosis of bovine brucellosis in adult herd vaccinated with Brucella abortus strain 19 reduced dose

Com o presente trabalho avaliou-se o uso de dose reduzida da vacina produzida com a amostra 19 de Brucella abortus, em rebanho adulto negativo para a enfermidade, por meio de técnicas de diagnóstico sorológico preconizadas pelo Programa Nacional de Controle e Erradicação da Brucelose e Tuberculose Animal e por um ensaio indireto de imunoadsorção enzimática (ELISA ID). A prova de fixação de complemento detectou 46,77 por cento de positivos, o antígeno acidificado tamponado 67,74 por cento, o 2-mercaptoetanol com soroaglutinação lenta 87,09 por cento e o ELISA ID 100 por cento. A dose reduzida interferiu no diagnóstico sorológico. Nenhuma das técnicas apresentou especificidade adequada para uso em rebanho nestas condições, até 3 meses após a vacinação.

The study evaluated the use of a reduced dose of the Brucella abortus strain 19 vaccine, in an adult herd negative for the disease, by serological diagnostic techniques, advocated by the Brazilian Program for Animal Brucellosis and Tuberculosis Control and Eradication, and by an indirect ELISA. The complement fixation test detecteed 46.77 percent positives, the rose bengal test 67.74 percent, the mercaptoethanol with standard agglutination test 87.09 percent and the ELISA ID 100 percent. The reduced dose influenced the serological diagnosis. None of the techniques reached a suitable specificity for use in the herd under those conditions, up to 3 months after vaccination.
