RESUMO Este artigo analisa o efeito de notícias com erros gramaticais, corrigidas ou atualizadas sobre a percepção de leitoras e leitores em relação à credibilidade da informação e sobre sua intenção de comportamento associada ao conteúdo dessa notícia. Investigamos esses efeitos em uma notícia sobre a vacinação contra a febre amarela junto a uma amostra de 1.648 indivíduos. Com base num desenho experimental, mensuramos os efeitos do veículo (G1 ou WhatsApp) e de cinco versões de um texto. Os achados mostram que o mesmo texto atribuído ao G1 ou a uma mensagem de WhatsApp foi percebido como mais credível no primeiro caso. Erros gramaticais, atualizações e correções em geral não afetaram a credibilidade da notícia nem a intenção de vacinação das participantes. Quando a notícia é atribuída ao G1, porém, a credibilidade da mensagem “corrigida” é significativamente maior que a credibilidade da mensagem com erros graves de gramática.

ABSTRACT This article analyzes the effect of news reports containing grammatical errors that have been corrected or updated, how readers perceive the credibility of this information, and their behavioral intention with the content in the news reports. We investigated these effects in a report on yellow fever vaccination with a sample of 1.648 individuals. Based on an experimental research design, we measured the effects of the vehicle (G1 or WhatsApp) and five versions of a text. The findings show that the same text assigned to G1 or a WhatsApp message was perceived as more credible in the first case. Grammatical errors, updates, and corrections, in general, did not affect the credibility of the news or the intention to be vaccinated. When the news is attributed to the G1, however, the credibility of the “corrected” message is significantly higher than the credibility of the message with serious grammar errors.

RESUMEN Este artículo analiza el efecto de noticias con errores gramaticales, corregidas o actualizadas sobre la percepción de las lectoras y de los lectores con relación con la credibilidad de la información y sobre su intención de comportamiento asociada al contenido de esa noticia. Investigamos esos efectos en una nota sobre la vacunación contra la fiebre amarilla con una muestra de 1.648 individuos. A partir de un diseño experimental, medimos los efectos del medio (G1 o WhatsApp) y de cinco versiones de un texto. Los hallazgos muestran que el mismo texto asociado a G1 o a un mensaje de WhatsApp se percibió como más creíble en el primer caso. Los errores gramaticales, actualizaciones y correcciones generalmente no afectaron la credibilidad de la noticia ni la intención de vacunación. Cuando la noticia se atribuye al G1, todavía, la credibilidad del mensaje “corregido” es significativamente mayor que la credibilidad del mensaje con graves errores gramaticales.

Objective: Disorders characterized by “distressing unexplained somatic symptoms” are challenging. In the ICD-11 Primary Health Care (PHC) Guidelines for Diagnosis and Management of Mental Disorders (ICD-11 PHC), a new category, bodily stress syndrome (BSS), was included to diagnose patients presenting unexplained somatic symptoms. The present study investigated the association of BSS with anxiety, depression, and four subgroups of physical symptoms in a Brazilian primary health care (PHC) sample. Methodology: As part of the international ICD-11 PHC study, 338 patients were evaluated by their primary care physicians, followed by testing with Clinical Interview Schedule (CIS-R) and World Health Organization Disability Assessment Schedule, Version 2.0 (WHODAS 2.0). BSS was diagnosed in the presence of at least three somatic symptoms associated with incapacity. The association between anxiety, depression, and four subgroups of physical symptoms with being a BSS case was analyzed. Results: The number of somatic symptoms was high in the overall sample of 338 patients (mean = 8.4), but even higher in the 131 BSS patients (10.2; p < 0.001). Most BSS patients (57.3%) had at least three symptoms from two, three, or four subgroups, and these were associated with anxiety and depression in 80.9% of these patients. The symptom subgroup most strongly associated with “being a BSS” case was the non-specific group (OR = 6.51; 95%CI 1.65-24.34), followed by musculoskeletal (OR = 2,31; 95%CI 1.19-4.72). Conclusion: Somatic symptoms were frequent in a sample of PHC patients in Brazil. In the present sample, one third were BSS cases and met the criteria for at least two symptom subgroups, supporting the hypothesis that different functional symptoms are related to each other.
