- Mediating Role of Basic Psychological Needs in the Association Between Exercise Goal Content and Subjective Well-Being in Portuguese Older AdultsPublication . Couto, Nuno; Antunes, Raul; Bento, T.; Pereira dos Santos de Sousa Vitorino, Anabela; Monteiro, Diogo; Cid, LuisBackground: This study aimed to examine the association between different exercise goals and their impact on subjective well-being (SWB) variables, namely, positive affect (PA), negative affect (NA), and satisfaction with life (SWL), as well as to explore the mediating role of basic psychological needs (BPNs) in this relationship within a sample of Portuguese older adults. Objectives: The present study aimed to analyze the association between extrinsic and intrinsic motivation for exercise, basic psychological needs (BPNs), and subjective well-being (SWB) in older Portuguese people. Methods: The sample study constituted 298 individuals (233 females, 65 males), aged between 60 and 90 years (M = 68.43; SD = 6.48). Through model four of the Process macro for SPSS version 3.5, a simple mediation analysis was carried out. Results: The results show that BPNs mediated the relationship between goal content for exercise health management and positive affect (PA) and satisfaction with life (SWL); goal content for exercise skill development and PA; goal content for exercise image, PA, and SWL; and goal content for exercise social affiliation and PA. Conclusions: Thus, we can conclude that BPNs stand out as a relevant mediator in the relationship between goal content for exercise and SWB variables, which reinforces the importance of BPNs in SWB promotion in the older population.
- Psychometric Properties and Rasch Validation of the Herth Hope Index in a Sample of Portuguese Higher Education Students During a PandemicPublication . Laranjeira, Carlos; Querido, Ana; Lourenço, Tânia; Charepe, Zaida; Ali, Amira Mohammed; Fekih-Romdhane, Feten; Yıldırım, Murat; Dixe, Maria dos AnjosA greater understanding of health-promoting factors, such as hope, is crucial for preventing and enhancing the mental health of higher education students. The Herth Hope Index (HHI) is a 12-item tool that has been widely used to assess a comprehensive, non-temporal perception of hope. While this instrument has been used extensively in adult populations, most studies focus on clinical populations. Additionally, the HHI reveals inconsistencies in terms of scale dimensionality and items to be retained. Therefore, this study sought to assess the HHI’s psychometric characteristics in a sample of Portuguese Higher Education students. The person response validity, internal scale validity, unidimensionality, and uniform differential item functioning were assessed using a Rasch rating scale model. A total of 2227 higher education students participated during the e-survey activation period (spring semester of 2020). The mean age of the sample was 22.5 ± 6.2 years (range 18–59 years). Three of the twelve items (#3, #5, and #6) failed to satisfy the established criterion for goodness of fit. Following the elimination of these three items, the resultant nine-item scale exhibited satisfactory item fit to the model, appropriate unidimensionality (52.4% of the variance explained), enough person goodness of fit, sufficient separation, and the absence of differential item functioning. The 9-item version of the HHI had psychometric properties comparable to the original 12-item version. This study also underscores the importance of validated instruments for assessing hope-based interventions in academic contexts. Further research is necessary to explore the potential dimensions inherent to the hope concept and to identify variations in hope profiles among items influenced by cultural attributes.
