89 349 - PublicationOpen AccessFood addiction and grazing: The role of difficulties in emotion regulation and negative urgency in university students(MDPI, 2023)
;Ribeiro, Andreia; ;Felix, Silvia ;Guimaraes, Carolina ;Machado, Barbara Cesar ;Goncalves, Sonia ;Lourdes, MartaConceicao, EvaUniversity students are a vulnerable population to the development of disordered eating, such as food addiction (FA) and grazing. FA is an emerging concept characterized by an intense desire to eat hyper-palatable foods. Grazing is characterized by the repetitive and unplanned ingestion of food throughout a period of time. Both FA and grazing have been associated with increased scores of negative urgency (NU) and difficulties in emotion regulation (ER). This study aims to evaluate the frequency of FA and grazing in a university population and to test the direct, total, and indirect effects—via FA—of ER and NU on repetitive eating and compulsive grazing. A total of 338 participants responded to a set of psychological measures assessing these variables. Thirty-six (10.7%) participants met the criteria for FA diagnosis and 184 (54.4%) presented grazing. Confirmatory factor analysis showed acceptable fit indexes for the model tested (χ2(1695) = 3167.575; p < 0.001; CFI = 0.955; NFI = 0.908; TLI = 0.953; SRMR = 0.085; RMSEA = 0.051; CI 90% (0.048; 0.053); P[RMSEA ≤ 0.05] = 0.318) and suggested that FA partially mediated the effect of difficulties in ER and NU on grazing, specifically on compulsive grazing. The results indicate that individuals with difficulties in ER and impulse control under negative emotions are more likely to engage in grazing if food addiction scores are higher. These results highlight the importance of assessing these variables, particularly in at-risk populations such as university students.Scopus© Citations 2 61 99 - PublicationOpen AccessProspective avenues in travel behavior research supported by the cognitive dissonance theory: A scoping reviewRecent findings on the relationship between travel choices and attitudes toward different modes of transport have highlighted the importance of Festinger’s Cognitive Dissonance Theory (CDT). Evidence suggests a bidirectional influence between travel behavior and attitudes, making CDT especially relevant. However, little attention has been paid to exploring CDT itself in the transportation domain. We present a scoping review that discusses the concepts defined by the seminal work of Festinger (1957) on CDT and recent considerations from psychology. We also discuss the gaps found in the transportation literature and suggest avenues for future research to enhance CDT’s applicability. A conceptual model is presented to provide a rationale of the theory and four main questions are considered to drive the discussions throughout the paper: (i) How have cognitive dissonance definitions been interpreted and applied in the literature?; (ii) How has the magnitude of inconsistency been measured?; (iii) To which constructs has the cognitive dissonance state been related?; (iv) To what extent have resistances to behavior and attitude changes been considered? Addressing these questions contributed to present clearer definitions about the constructs of CDT, particularly to the term ‘dissonance’, the magnitude of inconsistency function and both resistance to behavioral change and resistance to attitude change. As a result, this paper provides a logical decision-making process regarding travel mode choice, allowing a balance between the assessment of soft and hard policy interventions toward sustainable mobility.
28 824 - PublicationEmbargoThe Walsh Family Resilience Questionnaire: Validity evidence from Portugal(Wiley, 2024)
;Morais, Ines ;Carneiro, Francis Anne; ;Costa, Pedro AlexandreLeal, IsabelBackground Family resilience refers to a family's capacity to face and manage adversities, emerging as a stronger and more resourceful unit. A family system approach enlarges the lens to the broad relational network, identifying potential resources for resilience within the immediate and extended family. This approach emphasizes a family's innate ability to adapt in the face of adversities.
Objective
This study aims to test the psychometric properties of the Walsh Family Resilience Questionnaire (WFRQ) using a sample of Portuguese caregivers with children aged between 10 and 15 years.Method
A total of 267 caregivers of children aged 10 to 15 years completed a sociodemographic questionnaire and the WFRQ. Analyses were performed to evaluate the WFRQ's validity evidence based on the internal structure (i.e., dimensionality and reliability) and on its relationship to other variables.Results
The findings supported a 31-item version of the WFRQ with one third-order latent factor, three second-order factors, and nine first-order factors for the Portuguese population. The WFRQ exhibited satisfactory validity evidence based on the internal structure and relation to other variables.Conclusion
Overall, the results of this study demonstrate the suitability of the WFRQ as a holistic measure to gauge resilience at the family level, going beyond individual assessments.Implications
This instrument holds significant utility in family resilience research and clinical interventions involving families.114 17 - PublicationOpen AccessCorrelates of burnout and dropout intentions in medical students: A cross-sectional study(Elsevier, 2024)
; ;Oliveira, Pedro ;Novais, Filipa ;Almeida, Carla MariaTelles-Correia, DiogoBackground Burnout is a pervasive issue among medical students, exhibiting a high prevalence that jeopardizes their academic success and may also predispose them to more severe affective disorders such as depression. This study aims to explore the complex relationships between psychological capital (PsyCap), general social support, educational satisfaction, and burnout, and how these factors collectively influence dropout intentions.
Methods
A non-probabilistic convenience sample was collected through an online survey from first- and second-year medical students at a Faculty of Medicine in Portugal. The survey employed psychometric instruments to measure burnout (BAT-12), social support (F-SozU K-6), PsyCap (CPC-12R), satisfaction with education, and dropout intentions (Screening Instrument for Students At-Risk of Dropping Out). Structural equation modeling was applied to analyze the data from 351 participants.Results
The model demonstrated a significant positive association between burnout and dropout intentions ( = 0.37; p < 0.001), underscoring burnout as a direct correlate of dropout intentions alongside educational satisfaction ( = −0.25; p = 0.003) and PsyCap ( = −0.22; p = 0.005). Higher social support is associated with reduced burnout ( = −0.28; p < 0.001) and increased educational satisfaction ( = 0.22; p = 0.002).Limitations
The non-probabilistic sampling method prevents the generalization of the findings. The cross-sectional data do not permit the inference of temporal relationships between the studied variables.Conclusions
These findings emphasize the importance that burnout may have on dropout intentions, and contribute to the understanding of affective syndromes such as burnout in educational settings.Scopus© Citations 2 45 449 - PublicationEmbargoEarly childhood education and care around the world: An early start that prevails on reading literacy
This chapter delves into the interplay between family, socioeconomic status (SES) and Early Childhood Education and Care (ECEC), and educational outcomes in reading literacy, highlighting the importance of high-quality early education. In previous studies, SES, encompassing economic and social indicators like parental income, education, occupation, and the availability of educational resources, is recognized as a pivotal factor shaping a child's educational journey. Further previous studies have also highlighted the importance of high-quality early education on children’s later educational outcome. Using data from the PIRLS 2021 (The Progress in International Reading Literacy Study) and PISA 2018 (Programme for International Student Assessment), this research investigates the effect of early childhood education on reading literacy achievement among 4th graders and 15-year-old students around the world. Further, we also investigated if the ECEC and SES effects on reading literacy at later ages is conditional on countries' human development. Here we use the human development index by UNESCO. According to the results, there was a clear variation between the effects of early childhood education and care on later reading literacy outcome in the measured countries around the world. These differences in the effect underscores the importance of rethinking policies and practices, especially in those countries where the effect of early education seemed to be negative. There were also statistically significant interactions between ECEC duration and ESCS when estimating reading literacy by regression on the plausible values for reading literacy for both PIRLS and PISA. This interaction was dependent on the human development index. The findings of this study are essential for policymakers as they highlight the nuanced relationship between early education, socioeconomic status, and human development across different age groups and regions.
11 41 - PublicationOpen AccessAcademic success, engagement and self-efficacy of first-year university students: Personal variables and first-semester performanceHigher education can be hugely transformative for students and has an important role in empowering human capital, innovation, and society’s social, cultural, and environmental development. The expansion of higher education has promoted access for a more heterogeneous mix of students, but ensuring access does not guarantee academic success. This paper aims to analyse predictors of academic achievement in 447 first-year students in their 1st and 2nd semesters, considering variables including sex, age, parents’ educational level and grades on entering higher education, along with levels of students’ academic engagement and self-efficacy after some weeks at university. Results show statistically significant paths for sex, age, and GPA to 1st-semester achievement, for parent’s educational levels to perceived self-efficacy, for students’ academic engagement to 1st-semester achievement, and 1st-semester achievement to 2nd-semester achievement. Students’ academic engagement also had an indirect effect on the 2nd-semester achievement. The correlation between academic engagement and self-efficacy was positive, strong, and statistically significant. The model explained 35.2% of the variance in 2nd-semester achievement and 15.0% of the variance in 1st-semester achievement. Knowledge about predictors of academic achievement and the importance of engagement and self-efficacy will support timely interventions, promoting success and preventing failure and dropout.

;Melnik, Tamara; ;Pinho, Vanessa Dordron de ;Junior, José Antônio Spencer Hartmann ;Oliveira, Margareth da SilvaLopes, Fernanda MachadoBackground/Objectives: The use of scientific evidence for the diagnosis and treatment of mental disorders is crucial for achieving optimal clinical outcomes and providing high-quality care. This study investigates the knowledge, sources of evidence, and attitudes of Brazilian clinical psychologists regarding evidence-based practice in psychology (EBPP) and discusses barriers to its implementation. Methods: A total of 696 Brazilian clinical psychologists participated in an online questionnaire designed to assess their understanding of EBPP, their familiarity with scientific platforms/databases, and their professional development investments. Latent class analysis (LCA) was conducted, which can be used to identify subgroups of psychologists with similar patterns of professional and training characteristics. Results: The results indicate that while psychologists recognized the importance of EBPP for effective patient care, there was a significant gap in understanding its fundamental principles and concepts. Many participants reported the limited use of scientific databases, missing opportunities to access the latest research advancements. A lower percentage of psychologists consistently implemented EBPP in their clinical practice, highlighting a gap between knowledge and application. Four latent classes emerged from the LCA: I—experienced/established professional psychologist; II—academic psychologist; III—supervised traditional psychologist; and IV—young professional psychologist. Conclusions: This study emphasizes the need for better integration of EBPP into psychology curricula and continuing education programs. Enhancing clinical psychologists’ understanding and proficiency in EBPP can promote evidence-based decision-making and improve the quality of mental health care in Brazil. Efforts should be made to familiarize psychologists with reliable scientific databases, equip them with skills to critically appraise research, and foster a culture of lifelong learning and professional development. Additionally, it is essential to develop strategies tailored to the distinct profiles of professionals identified in this study, considering their training sources, reference usage, and knowledge of EBPP.13 98
