- A avaliação do hábito em praticantes de exercício físico: testando a validade do self-report behavioral automaticity indexPublication . Rodrigues, Filipe; Cid, Luis; Forte, Pedro; Teixeira, Diogo; Travassos, Bruno; Monteiro, DiogoOs comportamentos habituais são repetidos inconscientemente, sem intenção. A medição precisa do hábito é crucial para ajudar os investigadores a desenvolver e aplicar um modelo teórico sobre o hábito, com uma medida empiricamente válida. Desta forma, o objetivo do presente estudo foi testar a validade e a fiabilidade do Self-Report Behavior Automaticity Index numa amostra Portuguesa praticante de exercício físico. Foram recolhidos dados de duas amostras independentes, com um total de 590 adultos (mulheres= 311; homens= 279). Realizou-se uma análise fatorial confirmatória do modelo de medida de quatro itens do Self-Report Behavior Automaticity Index e uma análise de invariância entre duas amostras independentes. Adicionalmente, foi testado um modelo de mediação de forma a analisar o papel mediador da frequência semanal de exercício físico entre a experiência passada e o hábito. O modelo de medida do Self-Report Behavior Automaticity Index demonstrou um ajustamento aceitável em cada uma das amostras e os coeficientes de fiabilidade compósita foram adequados. O modelo de medida revelou ser invariante entre amostras, acrescentando, por isso um maior suporte à sua validade para avaliar o comportamento habitual. A frequência do exercício medeia a relação entre a experiência e o desenvolvimento do hábito, acrescentando evidências à teoria do hábito
- The relationship between teachers and peers’ motivational climates, needs satisfaction, and physical education grades: an AGT and SDT approachPublication . Rodrigues, Filipe; Monteiro, Diogo; Teixeira, Diogo S.; Cid, LuisGrounded in achievement goal theory and self-determination theory, this study aimed to examine the associations of students’ perception of learning- and performance-oriented climates created by teachers and peers on basic psychological needs satisfaction, and consequently their relationships with physical education grades. This study had a cross-sectional design, and 589 students aged between 10 and 18 years (M = 12.93; SD = 1.49) were recruited for analysis. Participants completed a multisection survey assessing motivational climates and basic psychological needs, and physical education grades were provided by the physical education teacher. Students’ perception of learning-oriented climates created by teachers and peers was positively and significantly associated with basic psychological needs satisfaction. Additionally, these learning-oriented climates presented a significant indirect association with physical education grades. On the other hand, the performance-oriented climate created by teachers had a negative and significant relationship with basic psychological needs satisfaction and displayed a negative indirect relationship with physical education grades. The performance-oriented climate created by peers had a positive and significant relationship with basic psychological needs satisfaction and displayed a positive indirect relationship with physical education grades. The perception of performance-oriented climates created by peers could represent a boost within the students in physical education features. Teachers have the responsibility of promoting task and learning environments in which students experience positive outcomes, not only on a motivational level but also on a cognitive level
- Understanding needs satisfaction and frustration in young athletes: factor structure and invariance analysisPublication . Monteiro, Diogo; Cid, Luis; Teixeira, Diogo S.; Fonseca, Teresa; Duarte-Mendes, Pedro; Silva, Luís M.; Rodrigues, FilipeSports research has been focused on the assessment of basic needs satisfaction, considering its absence as a representation of needs frustration. However, recent findings have suggested needs satisfaction and frustration as asymmetrical factors leading to differentiated outcomes. An accurate measurement of needs poses itself as a crucial aspect, facilitating coaches’ understanding of athlete’s motivational processes. This study aimed to examine the psychometric proprieties of the Basic Psychological Needs Satisfaction and Frustration Scale (BPNSFS) in a sample of Portuguese athletes. A multigroup analysis was conducted of gender, sport type, age, and years of sports practice. Additionally, needs satisfaction and needs frustration were tested as predictors of behavioral regulations examining the nomological validity of the BPNSFS. Data from 594 Portuguese athletes (38.6% female; Mage = 15.21; SD = 0.97) that represent two different sports (football and swimming) were analyzed. Confirmatory factor analysis and structural equation modeling procedures were followed to test the factor structure and nomological validity of the scale, respectively. Analyses indicated that the six-factor model provided an adequate fit (Comparative Fit Index = 0.947, Tucker–Lewis Index = 0.936, Standardized Root Mean Square = 0.039, Root Mean Square Error of Approximation = 0.048 (CI 90% = 0.043, 0.054)). Moreover, the multigroup analysis suggested invariance in the observed structure across groups. In addition, findings indicated a strong prediction between needs satisfaction and autonomous forms of motivation, whereas needs frustration predicted significantly controlled forms of motivation. The sport-adapted BPNSFS in a sample of Portuguese athletes seemed to be an adequate measure for the assessment of basic psychological needs satisfaction and frustration. Our findings suggested that this scale may be worth testing in future research in the sport context.
- Examining exercise motives between gender, age and activity: a first-order scale analysis and measurement invariancePublication . Rodrigues, Filipe; MOUTÃO, JOÃO; Teixeira, Diogo; Cid, Luis; Monteiro, DiogoConceptualizing an exercise program according to exercisers motives seems to be crucial. Thus, adequate and validated scale assessing motives for physical activity is necessary. This study aimed to translate and validate the Exercise Motives Inventory – 2 (EMI-2), a scale assessing fourteen motives for regular physical activity in Portuguese exercisers. In addition, comparison of motives between groups were made according to gender, age, and fitness activity. For scale validation, data from two independent samples were collected: calibration (n = 820; female = 499) and validation (n = 733; female = 451) participants. For scale reliability and mean difference analysis, data from a new sample was collected (n = 515; female = 342). Results showed that data did not fit the original 51-item model. After reviewing item loadings, two items were eliminated, since they presented factor loadings below acceptable. Hence, the revised model encompassing 49-item had an adequate fit. Convergent and discriminant validity was achieved in the revised model, displaying acceptable construct validity. In addition, invariance criteria were respected between female and male Portuguese exercisers. Regarding mean comparison analysis, differences were found between gender, and across age and fitness activities. Nevertheless, in overall the majority of exercisers indicated “general health” and “physiological” motives as the most valued. The EMI-2 is a reliable scale assessing motives in Portuguese exercisers. This study suggests that exercise programs should be conceptualized considering motives, but also gender, age, and fitness activity.
- On Redefining the Body Image Satisfaction Questionnaire: A Preliminary Test of MultidimensionalityPublication . Rodrigues, Filipe; Monteiro, Diogo; Flores, Pedro; Forte, PedroThe aim of the present study was to examine the Body Image Satisfaction Questionnaire (BISQ) as a ultidimensional instrument, designed to measure individuals’ body image satisfaction. A sample of 790 Portuguese healthy adults (female = 399; male = 391) aged 18 and 49 years old (M = 28.61, SD = 7.97) completed the BISQ. Exploratory factor analysis of the BISQ provided initial psychometric validity for a five-factor model assessing five dimensions of body image, namely, face, upper torso, lower torso, lower body, and overall body appearance. Confirmatory factor analysis supported this five-correlated model, in which a bifactor model provided the best fit to the data, defining a body image satisfaction factor and five specific factors. The BISQ clearly distinguished between various dimensions of body image satisfaction and showed satisfactory psychometric quality through factor analyses. This measure may have a broad application for research and practice, as a tool for capturing individual body image satisfaction
- Active Commuting: an opportunity to fight Both climate change and physical inactivityPublication . Figueiredo, Nuno; Rodrigues, Filipe; Morouço, Pedro; Monteiro, DiogoGlobal health, climate, and ecological conditions cannot be dissociated, and over the last decade, the impacts of climate change on health have been profoundly felt. In 2010, the transport sector has been responsible for the direct emission of 6.7 Gt of carbon dioxide (CO2), and these numbers are expected to double by 2050. Additionally, physical inactivity rates have been growing over the last years, with most individuals in developed countries still relying on their cars for daily transportation, despite the unexplored potential of daily commuting in the promotion of physical activity. Given the well-known link between chronic diseases and sedentary lifestyles, addressing both the upward tendency of public health costs and energy consumption obtained from fossil fuels can be, possibly, one of the greatest public health opportunities over the last century. In this paper, we explore the potential of active commuting as a contemporary approach to address both global issues, considering its benefits on several indicators of health, quality of life, and well-being, as well as environmental-friendly behaviors
- The Co-Occurrence of Satisfaction and Frustration of Basic Psychological Needs and Its Relationship with Exercisers’ MotivationPublication . Rodrigues, Filipe; Macedo, Rita; Teixeira, Diogo; Cid, Luis; Travassos, Bruno; Neiva, Henrique; Monteiro, DiogoAlthough the relationship between both need frustration and, particularly, need satisfaction and different motivational regulations for exercise has been widely examined in the literature, little is known about the co-occurrence of both need satisfaction and need frustration in the exercise context. Grounded in self determination theory, the present study aimed to examine the effects of both need satisfaction and frustration on motivational regulations for exercise, by applying a response surface analysis approach. In total, 477 regular exercisers aged 18–54 years participated in this study. The interaction between needs (high on both need satisfaction and frustration) displayed a positive and significant association with amotivation, integrated regulation, and intrinsic motivation. Considering the direction of the discrepancy (high vs. low levels of need satisfaction and frustration) related to the behavioral regulations, results showed that higher need satisfaction relative to need frustration was associated with more self-determined regulations of motivation. Contrarily, higher need satisfaction relative to need frustration was associated with lower scores on amotivation, external, introjected, and identified regulation. Overall, these findings extend previous literature, suggesting that need satisfaction and frustration are distinct factors that can be experienced simultaneously in individuals during exercise and that different degrees of both needs have different associations with behavioral regulations.
- How does exercising make you feel? The associations between positive and negative affect, life satisfaction, self-esteem, and vitalityPublication . Faustino, Tatiana; Santos, Abel; Teixeira, Eduardo; Cid, Luis; Monteiro, Diogo; Rodrigues, FilipeThe purpose of this study was to examine the relationship between regular physical exercise and affective responses to the behaviour, and to investigate the relationship with life satisfaction, self-esteem, and vitality. In total, 264 Portuguese exercisers (female = 157) aged between 18 and 69 years (M = 12.93; SD = 1.49) were considered for analysis in this study. Participants were regular exercisers with a mean year experience of 5.73 (SD = 3.19). Looking at the results, the structural model displayed acceptable fit to the data: χ2 (314) = 515.904; p < .001; CFI = .928; TLI = .919; RMSEA .049 [.042, .057]. Overall, significant direct effects were found as theoretically proposed, namely: exercise frequency displayed a positive and significant association with positive affect; positive affect was positively associated with life satisfaction, self-esteem, and subjective vitality; and, negative affect was negatively correlated with life satisfaction, self-esteem, and subjective vitality. Exercise frequency had a positive and significant indirect effect on life satisfaction, self-esteem, and subjective vitality via positive affect, but not via negative affect.
- Examining achievement goals in exercisers: adaptation and validation of the goal orientations in exercise measure (GOEM)Publication . Cid, Luis; Rodrigues, Filipe; Teixeira, Diogo S.; Morales-Sánchez, Verónica; Macedo, Rita; Monteiro, DiogoThe diferent criteria by which individuals evaluate their competence and defne the success (or failure) of their participation in exercise is a topic of interest. The present study aimed to translate and validate the Goal Orientation in Exercise Measure (GOEM) in a sample of Portuguese exercisers. Confrmatory factor analysis and multigroup analyses were developed in order to test the factor structure and measurement invariance of the measure, respectively. The present sample comprised 550 gym and health club exercisers (female=264; Mage=30.03±10.20), with an attendance of 3.06 times (SD=1.08) per week, and a mean exercise experience of 37.63 months (SD=2.37). Current results showed that the measurement model of the GOEM presented adequate ft (total sample model: χ2=108.65, df=34, B-S p= <.001, SRMR=.045, TLI=.960, CFI=.970, RMSEA=.060). Additionally, measurement invariance was achieved between genders and across diferent ftness activities. Present results showed that the predictive validity criterion was respected, since task-orientation positively and signifcantly predicted identifed regulation (β=.54) and intrinsic motivation (β=.43), whereas ego-orientation was positively associated with external regulation (β=.46) and amotivation (β=.39). Present fndings support the use of the measure for task and ego-orientation assessment, thus allowing further support for the Achievement Goal Theory framework expansion in gym and health clubs research
- Could tDCS Be a Potential Performance-Enhancing Tool for Acute Neurocognitive Modulation in eSports? A Perspective ReviewPublication . Machado, Sergio; Travassos, Bruno; Teixeira, Diogo; Rodrigues, Filipe; Filipe Cid Serra, Luis; Monteiro, DiogoCompetitive sports involve physical and cognitive skills. In traditional sports, there is a greater dependence on the development and performance of both motor and cognitive skills, unlike electronic sports (eSports), which depend much more on neurocognitive skills for success. However, little is known about neurocognitive functions and effective strategies designed to develop and optimize neurocognitive performance in eSports athletes. One such strategy is transcranial direct current stimulation (tDCS), characterized as a weak electric current applied on the scalp to induce prolonged changes in cortical excitability. Therefore, our objective is to propose anodal (a)-tDCS as a performance-enhancing tool for neurocognitive functions in eSports. In this manuscript, we discussed the neurocognitive processes that underlie exceptionally skilled performances in eSports and how tDCS could be used for acute modulation of these processes in eSports. Based on the results from tDCS studies in healthy people, professional athletes, and video game players, it seems that tDCS is applied over the left dorsolateral prefrontal cortex (DLPFC) as a potential performance-enhancing tool for neurocognition in eSports.
