- Influenza and COVID-19 vaccination intention in Portuguese adults from at-risk groups: a mixed-method studyPublication . Godinho, Cristina A.; Francisco, Rita; Gaspar, Rui; Henriques, Joana; Costa, Andreia; António, João; Costa, Diana; Fernandes, Teresa; Arriaga, MiguelBackground Seasonal influenza and COVID-19 vaccines are critical for protecting at-risk populations, yet uptake remains suboptimal in some priority groups. This study aimed to identify psychosocial and structural factors associated with vaccination intention and hesitancy among Portuguese adults from high-risk groups, including older adults, individuals with chronic conditions, healthcare professionals, and pregnant women. Methods A mixed-methods design was employed. A cross-sectional telephone survey applied to a probabilistic sample (n=474) assessed sociodemographic, psychological, and logistical predictors of intention to vaccinate against influenza and COVID-19 among older adults and individuals with chronic illnesses. Semi-structured interviews conducted with vaccine-hesitant healthcare professionals (n=13) and pregnant women (n=10) explored perceptions and experiences towards vaccination. Results Survey findings showed moderately high intentions to vaccinate, with higher scores for influenza than COVID-19. Older age, worry, belief in vaccine safety and efficacy, and healthcare provider recommendations were positively associated with vaccination intention. Conversely, concerns about side effects, preference for natural immunity, and work-related barriers were negatively associated with vaccination intention. Interview data revealed ambivalence toward seasonal vaccines, particularly COVID-19, due to perceived rapid development and limited longterm data. Healthcare professionals often distinguished between seasonal and the national vaccination programme vaccines, mentioning low personal risk and side effects as reasons for hesitancy related to seasonal vaccines. Pregnant women emphasized concerns about fetal safety and the importance of clear healthcare providers recommendations. Conclusions Psychosocial factors, including beliefs about disease severity and vaccine safety, play a central role in vaccination intention. Work-related structural barriers further contribute to hesitancy. These findings underscore the need for targeted communication strategies, healthcare providers engagement and employer-based vaccination programs to address both structural and motivational aspects of vaccination adherence within priority groups.
- Perceptions of fall prevention and engagement in social prescribing activities among older adults: a cross-sectional study in PortugalPublication . Matos, Cristiano; Baixinho, Cristina Rosa; Alarcão, Violeta; Henriques, Maria Adriana; Ferreira, Ricardo Oliveira; Nascimento, Tiago; Arriaga, Miguel; Alves, Tatiana; Nogueira, Paulo; Costa, AndreiaBackground: Falls are a major cause of injury, functional decline, and reduced quality of life among older adults, posing a significant public health challenge. Social prescribing is gaining relevance in gerontology, offering structured strategies to engage individuals in preventive activities, including fall prevention strategies, through engagement in community-based activities. Aim: To examine older adults’ perception of the relevance of personal protection and development activities (e.g., prevention against falling) and compare sociodemographic, behavioural, and engagement profiles between those who agree and those who disagree with its relevance. Methods: A cross-sectional study was conducted with 613 older adults aged 65–93 years. Data collection included sociodemographic, health-related, and behavioural/social engagement variables (including perceptions regarding the benefits of social prescribing and interest in community-based activities). For this analysis, participants were dichotomized based on their agreement with the relevance of personal protection and development activities (e.g., prevention against falling). Of the 569 participants included, 538 (94.5%) agreed with its relevance and 31 (5.5%) disagreed. Descriptive and exploratory analyses were conducted to compare the two groups across variables. Multivariate logistic regression analyses were conducted to explore independent predictors of agreement across sociodemographic, behavioural, social prescribing, and health-related variables. Results: Significant differences were observed between the groups in awareness of active ageing (p = 0.018), volunteering (p < 0.001), participation in social and community activities (p < 0.001), and hobbies like gardening, fishing, or cooking (p = 0.002). Those who agreed with the importance of personal protection and development activities were significantly more likely to value a range of initiatives, including social activities in recreational organizations, physical activity in the community (e.g., hiking), artistic and creative activities (e.g., visual arts, music), technical or technological activities (e.g., do-it-yourself, computers), and cultural enrichment activities (e.g., visiting museums), (p < 0.001). Multivariate analyses showed no effects of sociodemographic or health-related factors, whereas behavioural and engagement-related variables—including volunteering, hobbies, and several social prescribing activities—significantly predicted agreement with the relevance of personal protection and development activities. Discussion: The findings suggest that older adults who perceive fall prevention as relevant are more actively engaged in diverse health-promoting activities, including volunteering, hobbies, and community-based programmes. This pattern may reflect higher health literacy, stronger social networks, and proactive attitudes towards ageing. Conclusions: Perceptions of fall prevention are closely linked to broader patterns of engagement in health-promoting activities among older adults. Recognizing and addressing differences in how these activities are valued can inform more inclusive and targeted gerontological interventions.
- Fostering school belonging among Portuguese adolescents: psychosocial predictors and guidelines for educational actionPublication . Reis, Marta; Noronha, Catarina; Tomé, Gina; Carvalho, Marina; Rodrigues, Nuno Neto; Matos, Margarida Gaspar deIntroduction: School belonging is a key component of adolescent well-being, associated with academic success, mental health, and social inclusion. This study explores the levels of school belonging among Portuguese students and examines the psychosocial factors associated with this perception. Methods: Data from 3083 students (5th to 12th grade) obtained through the 2024 National Study by the Observatory of Psychological Health and Well-Being were analysed. Socio-emotional skills, well-being indicators, psychological symptoms, and school engagement variables were assessed using validated instruments. Statistical analyses included ANOVA and linear regression. Results: Overall, boys and younger students reported higher levels of school belonging. Sociability, resilience, confidence, school engagement, and and components of Positive Youth Development (PYD)—a strengths-based framework focusing on the internal and external assets that foster healthy youth development—such as competence and connection, were positively associated with school belonging. Conversely, depressive symptoms and experiences of bullying negatively predicted this outcome. Conclusions: This study’s findings highlight the need to reinforce inclusive educational practices, foster positive youth development, and promote protective relational dynamics within the school context.
- A call for CARE in animal behaviour: an holistic ethical research frameworkPublication . Badihi, Gal; Taylor-O’Connor, Jennifer; Daly, Gabriela Bezerra de Melo; Komeda, Viola; Daoudi-Simison, Sophia; Rodrigues, Evelina D.; Webster, Michael M.; Altschul, Drew M.; Hobaiter, Catherine; Wiltshire, Charlotte; Klein, Harmonie; Freymann, Elodie; Grund, Charlotte; Soldati, Adrian; Henderson, Matthew; Leroux, Maël M.; Slania, Nora E.Despite increasing awareness of animal welfare, there are vast discrepancies between legal protections and recommended practices for different species, in different countries and at different institutions. While many guidelines are now available, they often target specific research contexts or species, leaving a gap in comprehensiveethicaloversight across the entireresearchprocess.Withinanimalbehaviour research,thereis abias for consideringethicsduringonlythemethodologyanddesignphase.This oftenmeansonly the immediate impact onanimalsdirectly involved inthe researchis accountedfor.

CARE encourages researchers and academic bodies to (1) Consult existing (academic and traditional) knowledge on the study species, local human—animal interactions, their environment and previously implemented ethical practices and to reflect on personal experience and biases when approaching a study question; (2) seek Approval from relevant bodies (e.g. institutional ethics committees and local and government authorities) even when not mandatory; (3) uphold ethical standards while carrying out Research and (4) Evaluate the short- and long-term impacts of the specific study. Our framework is designed to distribute accountability at every level of the academic system, from individual researchers to their institutions, funding bodies and publishers. We pitch this framework as a ‘version 1.0’ to recognize the fast-evolving nature of ethical standards in animal behaviour research and to allow space for improvement. CARE provides a necessary infrastructure for addressing systemic biases and ensuring ethically sound, socially responsible and environmentally sustainable animal behaviour research.
- Promoting mental health at schools - PROMEHS: impact of curriculum implementation in PortugalPublication . Simões, Celeste; Santos, Margarida Frade; Lebre, Paula; Canha, Lúcia; Santos, Anabela Caetano; Fonseca, Ana; Santos, Dória; Murgo, Camélia; Matos, Margarida Gaspar de; Grazzani, IlariaDespite evidence of the positive impact of school-based mental health promotion interventions, there remains a need for robust studies, particularly to evaluate newly developed programs, in order to promote the adoption of best practices and identify effective intervention strategies. This study aimed to evaluate the impact of implementing the PROMEHS curriculum in Portugal in a school setting, using a sample of children and adolescents (N=1,764). A longitudinal quasi-experimental design was adopted with an experimental group and a waitlist control group, assessed at the pre- and post-test phases of implementation. Data were collected from teachers, parents/guardians, and students using a set of instruments: the Strengths and Difficulties Questionnaire (SDQ), the Social-Emotional Skills (SSIS-SEL Brief Scales), Academic Competence, Resilience (CD-RISC10), and PROMEHS impact. The results indicate a significant impact on students’ socioemotional competencies and academic outcomes, as well as a reduction in difficulties, according to teacher assessments. No statistically significant results were found in the assessments of parents/guardians or the students. However, the evaluation of the program impact across all three informant sources was highly positive. Overall, the findings demonstrate the effectiveness of PROMEHS in promoting students’ socioemotional development and highlight the importance of this type of program in Portuguese schools.
- Understanding academic evaluation anxiety in Portuguese adolescents: a psychosocial and educational perspectivePublication . Reis, Marta; Noronha, Catarina; Tomé, Gina; Carvalho, Marina; Rodrigues, Nuno Neto; Matos, Margarida Gaspar deObjectives: Academic Evaluation Anxiety is a significant psychological concern among adolescents, with well-documented impacts on academic performance, emotional well-being, and school engagement. In Portugal, recent evidence suggests growing pressure on students to achieve high academic standards, with psychosocial variables such as resilience, perceived support, and school environment playing a crucial role. This study aims to examine the prevalence and psychosocial predictors of Academic Evaluation Anxiety in Portuguese students, and to identify risk and protective factors that inform educational practice. Methods: This cross-sectional, quantitative study analysed data from 3083 students (5th to 12th grade) from the 2024 National Study by the Observatory of Psychological Health and Well-Being. Validated instruments were used, including the Depression, Anxiety and Stress Scale-21 items (DASS-21), the Social and Emotional Skills Scale (SSES), the Health Behaviour in School-aged Children (HBSC) psychological symptoms and well-being indices, the Positive Youth Development (PYD) scale, and the School Environment Scale. Statistical analyses included descriptive measures, one-way ANOVAs, and multivariate linear regression. Results: Academic Evaluation Anxiety was significantly higher among female students (Mean = 2.80, SD = 0.93) compared to male students (Mean = 2.16, SD = 1.10), representing approximately 30% higher mean levels of anxiety in girls (F = 306.206, p < 0.001). Resilience (β = −0.38, p < 0.001), self-confidence (β = −0.07, p = 0.02), and creativity (β = −0.06, p = 0.01) emerged as protective factors, whereas cooperation (β = 0.23, p < 0.001), teacher relationships (β = 0.08, p < 0.001), bullying (β = 0.07, p < 0.001), and school environment (β = 0.05, p = 0.03) were positively associated with anxiety levels. Conclusions: Academic Evaluation Anxiety is highly prevalent among Portuguese adolescents, with girls reporting significantly higher levels than boys. Resilience, self-confidence, and creativity act as protective factors, while bullying, teacher relationships, cooperation, and negative school climate increase vulnerability. These findings highlight the need for whole-school strategies that strengthen socio-emotional competencies and create psychologically safe learning environments to support both well-being and academic success.
- Long COVID as a risk factor for hypersomnolence and fatigue: insights from the 2nd International Covid Sleep Study Collaboration (ICOSS-2)Publication . Sarkanen, Tomi; Merikanto, Ilona; Bjorvatn, Bjorn; Chung, Frances; Holzinger, Brigitte; Morin, Charles M.; Penzel, Thomas; Gennaro, Luigi de; Wing, Yun Kwok; Benedict, Christian; Xue, Pei; Reis, Cátia; Korman, Maria; Landtblom, Anne-Marie; Matsui, Kentaro; Hrubos-Strom, Harald; Mota-Rolim, Sergio; Nadorff, Michael R.; Berezin, Linor; Liu, Yaping; Scarpelli, Serena; Brandão, Luiz E. M.; Cedernaes, Jonathan; Partinen, Eemil; Bolstad, Courtney J.; Plazzi, Giuseppe; Espie, Colin A.; Partinen, Markku; Dauvilliers, YvesBackground: Hypersomnolence, defined as excessive daytime sleepiness (EDS), excessive quantity of sleep (EQS), sleep inertia, and fatigue reduce quality of life. We assessed associations of the COVID-19 pandemic, infection without long-term sequalae (short COVID, SC), and long COVID (LC) on hypersomnolence and fatigue in a large population across different countries. Methods: As part of an online questionnaire (ICOSS-2), we assessed EDS via the Epworth Sleepiness Scale (ESS), fatigue via Fatigue Severity Scale (FSS), and sleep duration at night and per 24 h. We also assessed the associations with EDS, sleep inertia, fatigue and napping by their frequencies, during the pandemic in COVID-negative, SC and LC participants. Results: The final cohort comprised 13,656 participants (69.1 % women, 42.7 ± 16.6 years), with 12.4 % classified SC and 7.5 % LC. ESS scores were higher in LC (9.16, 95 % CI [8.78, 9.53]) compared to SC (7.26, [6.97, 7.55]) and COVID-negative (6.53, [6.43, 6.63]). LC also had higher odds of ESS>10 (OR 1.58, [1.18,2.09]). FSS scores were higher in LC (median 51, IQR 39–59) than SC (34, 25–44) and COVID-negative (35, 25–45), with LC having 2.22 higher odds of severe fatigue. LC cases also reported more EQS (?10/24 h) than COVID-negative. Worsening of EDS, fatigue, sleep inertia, and napping was reported during pandemic to a greater extent in LC. Conclusions: LC was associated with higher levels of hypersomnolence and fatigue than in SC or COVID-negative participants, highlighting the need for interventions and future research focusing on sleep symptoms and their relation to long-term health outcomes.

- Dispositional critical thinking, positive youth development, and social contribution in Spanish emerging adultsPublication . Gomez-Baya, Diego; Branquinho, Cátia; Mendoza-Berjano, Ramon; Garcia-Moro, Francisco JoseDispositional critical thinking has been linked to positive performance in different life domains, such as better academic performance and professional practice, as well as better psychological adjustment. This study had the aim to examine the associations between positive youth development, dispositional critical thinking, and social contribution in a sample of Spanish undergraduates and to test the mediational role of the 5Cs of positive youth development (i.e., confidence, competence, caring, character, and connection) in the relationship between dispositional critical thinking and social contribution. A cross-sectional study was conducted during the spring of 2024 by administering an online self-report. The sample comprised 370 students (67.2% women) aged from 18 to 29 (M = 21.29; SD = 3.61) enrolled at 10 universities in the region of Andalusia (Spain). The results showed a multiple partial mediation of character and caring in the relationship between dispositional critical thinking and social contribution. This model indicated that dispositional critical thinking was associated with more character and caring, and, in turn, these dimensions of positive youth development were associated with more social contribution. These results underline the need to promote dispositional critical thinking and the positive youth development components of character and caring to increase social contribution in undergraduate students.
