RESUMO
OBJECTIVE: this study aims to verify the stages of evidence of validity of the voice-adapted present perceived control scale (V-APPCS) in its translated and cross-culturally adapted version for the Brazilian Portuguese "Voice-Adapted Present Perceived Control Scale" and to estimate the psychometric measurements of the properties of its items based on the item response theory (IRT). METHODS: the instrument underwent a process of translation and cross-cultural adaptation for the Brazilian Portuguese, the process was carried out by two qualified translators, native in the destination language, and fluent in the language and culture of origin. The first translated version of the protocol was forwarded to a back-translation, performed by a third bilingual Brazilian translator. The translations were analyzed and compared by a committee composed of five speech therapists who are specialists in voice and with proficiency in the English language. The empirical study used data from 168 individuals, 127 had voice problems and 41 vocally healthy ones. For the stages of validity evidence, the following analyses were performed: Cronbach's alpha, exploratory factor analysis, confirmatory factor analysis and IRT. RESULTS: The stages of translation and cross-cultural adaptation allowed linguistic adjustments to be made so that the items were understandable and suitable for use in Brazil. The adequacy, structure, and application of the items were confirmed through the application of the final version of the scale in twenty individuals in a real context. The instrument in its Brazilian version presented good internal consistency, with bifactorial structure the exploratory factor analysis, besides presenting satisfactory values in the adjustment indexes of the model, confirming the structure of the confirmatory factor Analysis. The IT was applied to evaluate the parameters discrimination (a) and difficulty (b) of the items of the instrument; item 5 "I have control over my day-to-day reactions to the voice problem." Presented itself as a more discriminative item and item 8 "My reaction to the voice problem is not under my control." As an item of greater difficulty. CONCLUSION: The V-APPCS, translated, cross-culturally adapted, and validated, is robust and adequate to represent the construct in the Brazilian versions.
RESUMO
Fundamento: la OMS considera que la amenaza de la COVID-19 y la influencia de las medidas para su prevención están causando un fuerte impacto psicológico en las sociedades. Objetivo: valorar la repercusión de la pandemia de COVID-19 en el orden psicosocial en estudiantes de Medicina de la Facultad de Ciencias Médicas "Julio Trigo López". Métodos: se realizó un estudio descriptivo y transversal en el periodo comprendido entre el 2 de abril-2 de julio de 2021, en la Universidad de Ciencias Médicas de La Habana. Se utilizaron métodos teóricos para la fundamentación de la investigación y empírico: cuestionario a estudiantes de la carrera de Medicina. Se estudiaron las variables: sexo, ansiedad de estado acorde con la escala de ansiedad generalizada y factores que influyeron en los cambios de orden personal. Resultados: hubo predominio del sexo femenino. Se constató que la mayoría (81,7 %) presentó algún grado de ansiedad, con supremacía de la leve, seguida de la moderada, siendo esta última más marcada en el sexo femenino. Como factores generadores de ansiedad, predominó el retraso académico, seguido del temor al contagio e incomprensión por parte de los profesores. Como factores determinantes de cambios en el orden personal, se encontró la influencia de lo emocional dado por cambios en el estilo de vida. Conclusiones: la pandemia de COVID-19 ha causado cambios en el orden personal, psicológico y social en los estudiantes de Medicina, marcados por aspectos relacionados fundamentalmente con las preocupaciones académicas.
Background: WHO considers that the threat of COVID-19 and the influence of its prevention measures are causing a strong psychological impact on societies. Objective: to assess the repercussion of the COVID-19 pandemic in the psychosocial order in Medicine students of the "Julio Trigo López" Faculty of Medical Sciences. Methods: a descriptive and cross-sectional study was carried out from April 2 to July 2, 2021, at Havana University of Medical Sciences. Theoretical methods were used for the foundation of the investigation and empirical ones: questionnaire to students of the Medicine degree. The variables were studied: sex, anxiety according to the generalized anxiety scale and factors that influenced the changes of personal facts. Results: there was a predominance of the female sex. It was found that the majority (81.7%) presented some degree of anxiety, with mild predominance, followed by moderate, the latter being more marked in the female sex. As anxiety-generating factors, academic delay predominated, followed by fear of contagion and misunderstanding by teachers. As determinant factors of changes in the personal order, the influence of the emotional given by changes in lifestyle was found. Conclusions: COVID-19 pandemic has caused changes in the personal, psychological, and social order of medical students, marked by aspects fundamentally related to academic concerns.

OBJECTIVE: To investigate the psychometric properties of the Voice-Related Quality of Life (V-RQOL) questionnaire in Brazilian Portuguese by assessing its reliability and conducting exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). METHODS: This research was carried out in two stages: (1) a document-based retrospective approach and (2) a field study step. The study included 566 dysphonic and vocally healthy individuals. For data collection, the Vocal Screening Protocol and the V-RQOL questionnaire were used, and these measures were later statistically analyzed through descriptive analysis, reliability tests, CFA, and EFA. Ethical issues were considered. RESULTS: A Cronbach's alpha coefficient of 0.916 was observed, indicating good internal consistency for the V-RQOL questionnaire. The item-total correlation coefficient indicated that the items had good correlation with each other and with the construct, with values higher than 0.30. EFA was performed based on the Kaiser-Meyer-Olkin index and Bartlett's test of sphericity, which indicated the adequacy of the tested sample. The items presented commonality of >0.30 and satisfactory factor loadings, resulting in a single factor. The unifactorial structure of the V-RQOL questionnaire was confirmed by CFA. CONCLUSION: EFA and CFA indicated that a single factor should be adopted to encompass all the items of the V-RQOL questionnaire.
