- Perceived vulnerability to disease: adaptation and validation of the PVD-brPublication . Do Bú, Emerson Araújo; Alexandre, Maria Edna Silva De; Rezende, Alessandro; Bezerra, Viviane Alves dos SantosPerceived vulnerability to disease is characterized by the extent to which individuals perceive themselves to be susceptible to contracting infectious diseases, as well as by the emotional discomfort that results from assessing the risk of getting contaminated by pathogens. The PVD self-report scale, which measures this construct, is widely used internationally. However, it has not yet been adapted for Brazil. To address this gap, we adapted and validated the PVD scale for the Brazilian context (PVD-br) in four studies. Study 1 (N = 39) addressed translation, expert validation, and assessment of the comprehensibility of the scale’s items. Study 2 (N = 200) showed that the items were organized into two correlated factors and tested the scale’s items quality using the Item Response Theory. Study 3 (N = 201) confirmed the bifactorial structure and examined the invariance of PVD-br for men and women, while Study 4 analyzed the convergent (N = 432) and discriminant (N = 181) validity of the instrument. Results indicate strong evidence of content, factorial, and criterion validity.
- Representações e ancoragens sociais do novo coronavírus e do tratamento da COVID-19 por brasileirosPublication . Bú, Emerson Araújo Do; Alexandre, Maria Edna Silva De; Bezerra, Viviane Alves dos Santos; Sá-Serafim, Roseane; Coutinho, Maria Da Penha De LimaObjetivou-se neste estudo apreender a gênese das representações sociais do novo coronavírus, bem como do tratamento da COVID-19, considerando-se diferentes ancoragens sociais de brasileiros. Contou-se com 595 participantes, predominantemente do sexo feminino (69,9%) e da região Nordeste do Brasil (64,9%). Os dados, coletados através de um questionário online, permitiram análises de Classificações Hierárquicas Descendentes, indicando que a gênese das representações sociais do novo coronavírus é marcada por preocupações relativas à sua disseminação e implicações psicossociais e afetivas. Já o campo representacional do tratamento enfatiza a remissão ou a amenização dos sintomas causados pela COVID-19. As variações nas representações sociais identificadas nesta pesquisa, em função dos diferentes grupos sociais, indicam que futuras intervenções devem considerar as especificidades de cada um deles na disseminação de representações e práticas sociais direcionadas para conter o estado pandêmico.
- Neuroticism, stress, and rumination in anxiety and depression of people with Vitiligo: An explanatory modelPublication . Bú, Emerson Araújo Do; Santos, Vitória Medeiros Dos; Lima, Kaline Silva; Pereira, Cicero Roberto; Alexandre, Maria Edna Silva De; Bezerra, Viviane Alves dos SantosPsychological impacts of Vitiligo have been demonstrated, and associations of the skin disease with anxiety and depression disorders have already been shown. However, it is still unclear the role of individuals’ personality factors, such as neuroticism, stress, and rumination, as well as sociodemographic characteristics of people with Vitiligo in such disorders. We conducted a study in a community sample of individuals with Vitiligo (N = 324) aiming to test the hypothesis that neuroticism, stress, and rumination are subjacent to these individuals’ anxiety and depression symptomatology. We also explored whether individuals’ gender might favor the onset or wors- ening of the psychological consequences of such disorders. Results showed that the relationship between neuroticism, anxiety and depression was mediated by stress and rumination (brooding), being this effect moderated by the participants’ gender. Specifically, women’s reflection and stress seemed to be important mechanisms to predict their anxiety and depression symptoms, whereas brooding predicts such disorders’ symptomatology in men with Vitiligo. These findings may guide future research and clinical interventions for this population, for which it is necessary to consider the psychological consequences of the disease and not just its physiological aspects.
- Representational Structure of Suicide by College Students and Its Psychosocial BrandsPublication . Alexandre, Maria Edna Silva de; Bezerra, Viviane Alves dos Santos; Do Bú, Emerson AraújoThis study aimed to identify the social representations of suicide elaborated by undergraduate and post-graduate students from Brazil. There were a number of 1053 undergraduate (37.1%) and post-graduate (62.9%) students, with an average age of 26.82 (SD = 5.88), mainly females (76.4%) who reside in the south-eastern region of Brazil (41.7%). For data collection, two questionnaireswere utilized, a socio-demographic one and another that refers to the Free Word Association Technique. Data were analyzed by the software IRaMuTeQ, which allowed the execution of prototypical analyses as well as similarity ones. Results from these analyses indicate that the representational structure of suicide, created by these students, is organized around a central core that evinces the consolidation of a suicide representation directly linked to death and psychological factors, such as sadness, pain, depression, desperation, and suffering; also, there are differences on the ways to represent suicide as a function of the education level and the field of knowledge variables according to the participants. Generally speaking, the analyses developed point to the presence of psychosocial brands in the way suicide is represented, which must be taken into consideration when building interventions focused on preventing it for college students.
