- COVID‐19 vaccination acceptance: A case of interplay between political and health dimensionsPublication . DA SILVA LIMA, KALINE; Bú, Emerson Do; Dantas Silva, Washington Allysson; P. Miranda, Mariana; Pereira, C.R.Vaccines are essential for the eradication of diseases. Yet for many reasons, individuals do not embrace them completely. In the COVID- 19 pandemic and with the possibility of the Brazilian population’s immunization against the disease, both political and health- related dimensions might have had a role in individual COVID- 19 vaccination acceptance. In two studies (n = 974), we tested the hypothesis that participants’ vaccination acceptance is related to their past vote in the 2018 Brazilian presidential election (being or not being a Jair Bolsonaro voter) and their different levels of perceived vulnerability to disease (PVD). We further tested whether Bolsonaro’s opposition or ambiguous messages towards vaccination (vs. control) increased vaccination rejection among those who have (vs. have not) voted for him and who are low (vs. high) in PVD. Results show that Bolsonaro (vs. non- Bolsonaro) voters accepted less vaccination, with higher rejection rates when participants expressed low (vs. high) PVD. Also, when primed either with Bolsonaro’s opposed or ambiguous messages towards COVID- 19 vaccination, such participants accepted less vaccines (vs. participants primed with neutral information). These findings are the first to show that the COVID- 19 vaccine acceptance is related to their past vote and leadership influence but also different levels of perceived vulnerability to disease.
- From family conflicts to suicide risk through deliberate self-harm online content in adolescents and young adultsPublication . Fuschini, Beatriz; Duarte, Eva; P. Miranda, Mariana; Gouveia-Pereira, Mariaself-harm (DSH) and even suicidal thoughts and behaviors. Research also shows that adolescents are increasingly engaging in online DSH activities. However, studies on this topic are scarce. Aims: This study’s first goal is to replicate the effect of family conflicts on suicidal ideation (SI) and, according to the gateway theory, include DSH diversity as a step preceding SI. Second, we aim to consider online activities in understanding suicidal risk. We start by describing online DSH activities, and propose a sequential mediation model in which family conflicts predict DSH and SI through online DSH activities. Methods: The convenience sample of this cross-sectional study consisted of 357 adolescents and young adults between 12 and 22 years old who completed a self-report questionnaire measuring family conflicts, online DSH activities, identification with DSH-related content creators, DSH, and suicidal ideation. Results: The results showed that 85.3% of our community sample used the internet for DSH-related purposes. Results also revealed an independent mediation effect of DSH diversity on the relationship between family conflicts and SI, and a sequential mediation effect of online DSH activities, identification, and DSH diversity. Conclusions: Engaging in online DSH activities is only predictive of DSH or SI if adolescents perceive a shared identity with this community of creators. The findings might yield implications regarding the design of prevention strategies that include a further supervision of online platforms and psychological interventions that incorporate the family system and peers
