- Assessment in Sport and Exercise Psychology: Considerations and Recommendations for Translation and Validation of QuestionnairesPublication . Cid, Luis; Monteiro, Diogo; Teixeira, Diogo Santos; Evmenenko, Anastasiia; Andrade, Ana; Bento, Teresa; Vitorino, Anabela; Couto, Nuno; Rodrigues, FilipeTranslating and validating measurement instruments in sport and exercise psychology is not an easy task. Rather, it is a task that requires effort and time, for the process is not limited to a simple translation to translate words from one language to another, just in order to make valid and reliable measure. All researchers should be aware that the only proper way is to adopt rigorous and robust methodologies to conduct the process from the preliminary stage of translation to reaching the validation stage of the psychological variable. Only so is it possible to avoid creating fragile and inadequate psychological assessment instruments that can jeopardize the entire investigation to be held with its use. Thus, the main objective of this work is to promote reflection and discussion on the subject by presenting some considerations and recommendations about translation and validation of questionnaires for psychological assessment applied to sport and exercise domain.
- 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 Santos; 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
- Changing behavior towards physical activity and exercisePublication . Rodrigues, Filipe; Bastos, Vasco; Teixeira, Diogo Santos; Monteiro, DiogoA inatividade física constitui um desafio de saúde pública que resiste a décadas de intervenções focadas meramente na educação e na decisão racional. Esta obra confronta esse paradigma, propondo uma abordagem integradora e contemporânea sobre a ciência da mudança comportamental aplicada ao exercício. Partindo das limitações dos modelos sociocognitivos clássicos na explicação da "lacuna intenção comportamento", o texto aprofunda as Teorias de Duplo Processamento. A análise centra-se na complexa interação entre sistemas reflexivos e impulsivos, explorando determinantes críticos como a resposta afetiva ao esforço, a formação de hábitos e a tendência evolutiva para a minimização do esforço. Argumenta-se que o comportamento humano não resulta apenas da vontade, mas de mecanismos automáticos e hedónicos frequentemente negligenciados na prática clínica. Através da exposição de modelos inovadores, como a Affective-Reflective Theory e o Physical Activity Adoption and Maintenance Model, fundamenta-se a necessidade de transitar de uma prescrição técnica para uma "arquitetura de experiências". A obra defende que a adesão sustentada depende do alinhamento estratégico entre a cognição e a resposta afetiva, reposicionando o prazer como uma variável clínica essencial. Trata-se de um recurso fundamental para a atualização científica de investigadores e profissionais que procuram estratégias baseadas na evidência para promover estilos de vida ativos.
- Erratum to: Muscle Strength Matters Most for Risk of Falling Apart from Body Mass Index in Older Adults: A Mediated-Moderation AnalysisPublication . Rodrigues, Filipe; Izquierdo, Mikel; Monteiro, Diogo; Jacinto, Miguel; Matos, Rui; Amaro, Nuno; Antunes, Raul; Teixeira, Diogo Santos
- Fitness instructor’s role on exercise adherence in Portugal: the importance of need-supportive behaviors and motivational climatesPublication . Rodrigues, Filipe; Monteiro, Diogo; Teixeira, Diogo Santos; Cid, LuisThe present study aimed to examine the association between fitness instructors’ interpersonal behaviors and motivational climates and exercise adherence. Two studies were conducted: in the first study, the effect of need-supportive and need-thwarting behaviors on basic psychological needs, and consequently on exercise adherence was analyzed; in the second study, the effect of ego and task-involving motivational climates on basic psychological needs, and consequently on exercise adherence was examined. Data was collected from several exercisers engaged in fitness activities in several gym and health clubs in Portugal. The results showed a positive association between need-supportive behaviors, task-involving climate, and basic psychological needs. These needs were respectively positively and significantly correlated with exercise adherence. Contrarily, need-thwarting behaviors displayed a negative, while ego-involving climates no association at all, with basic psychological needs. Overall, the data clearly shows an association between the way the fitness instructor is perceived by the exerciser and the number of accesses that the exerciser will have in the six months following the moment of the initial assessment. Therefore, fitness instructors have a considerable capacity to positively influence the exerciser's adherence, by creating a supportive environment during the training session.
- Muscle Strength Matters Most for Risk of Falling Apart from Body Mass Index in Older Adults: A Mediated-Moderation AnalysisPublication . Rodrigues, Filipe; Izquierdo, Mikel; Monteiro, Diogo; Jacinto, Miguel; Matos, Rui; Amaro, Nuno; Antunes, Raul; Teixeira, Diogo SantosThe primary objective of this study was to analyze the moderating effect of body mass index (BMI) on the association between lower body strength, agility, and dynamic balance, considering the mediating influence of lower body flexibility and aerobic endurance in community-dwelling older adults. This study included a sample of 607 community-dwelling older adults (female = 443; male = 164) aged between 60 and 79 years (M = 69.24; SD = 5.12). Participants had a mean body mass index of 28.33kg/m2 (SD = 4.45). In the mediation-moderation model, positive associations were found between lower body strength and lower body flexibility, aerobic endurance, and agility and dynamic balance (p < 0.05). As for the moderation effects and interactions, BMI was found to have a significant interaction with lower body strength on agility and dynamic balance (β = −.04, [−.06, −.03]), representing an R2-change of 0.04 (p <.001). Conditional direct effects were estimated at BMI scores of 23.9 (β = −.09, [−.15, −.03]), 27.7 (β = −.19, [−.24, −.14]), and 32.7 (β = −.33, [−.40, −.26]) kg/m2. Older adults with high levels of muscular strength tended to have shorter timed up-and-go test times, regardless of BMI. Also, individuals with lower levels of lower body strength were found to have longer timed up-and-go test times, and this relationship became more pronounced with increasing BMI.
- Preference for and tolerance of exercise intensity: the mediating role of Vitality in Exercise HabitPublication . Faria, João; Andrade, Ana; Evmenenko, Anastasiia; Monteiro, Diogo; Rodrigues, Filipe; Marques, Paulo; Cid, Luis; Teixeira, Diogo SantosThe aim of the current exploratory study was to test the mediation role of subjective vitality in the relation between the intensity-traits and exercise habit, thus helping to understand the role of preference and tolerance in well-being and behavioral outcomes. The sample comprised 299 gym exercisers (39% men) with an average age of 36.4 years (SD = 10.61). In general, the present sample of exercisers manifested a preference and tolerance for moderate intensity exercises/activities. The intensity traits were positively associated with subjective vitality and exercise habit, and vitality partially mediated both models. Globally, the intensity-traits presented small to moderate effects in the tested variables. Both preference and tolerance presented positive associations with vitality and habit in the present study and results depict some preliminary evidence that the intensity-traits related to exercise may be relevant for health club professionals adjust their intervention aiming to promote a better subjective experience and exercise adherence.
- Set to fail: Affective dynamics in a resistance training program designed to reach muscle concentric failurePublication . Bastos, Vasco; Andrade, Ana Jesus; Rodrigues, Filipe; Monteiro, Diogo; Cid, Luis; Teixeira, Diogo SantosGrounded in hedonic assumptions, evidence suggests that people tend to engage in activities they consider pleasurable and enjoyable, while trying to avoid pain and displeasure. This suggests that the dynamic between positive and negative affect can influence current behavior and the intentions to continue performing. Regarding resistance training (RT), research focusing on how to promote a better affective response is still scarce and much needed. Given existing limitations and theoretical suggestions, a RT program was developed and applied to recreational exercisers in a quasi-experimental design aiming to (1) explore the affective response dynamic through an assessment after the last set of each exercise; and (2) analyze possible differences of preference and tolerance profiles in affective variables (core affect and enjoyment). For that purpose, 43 participants (21 male and 22 female; Mage = 34.69 ± 6.71 years; Mexperience = 8.32 ± 4.54 years; MBMI = 24.26 ± 2.64 kg/m2) accepted to participate in this study. Descriptive statistics, correlational, and group comparisons analyses were performed to provide evidence for proposed objectives. The present study showed that measures of affective valence/arousal applied immediately after a set represents a feasible and ecologically valid approach to tap core affect. Results presented evidence that recreationally trained exercisers in a common RT program would need a minimum of one measurement to assess the affective response. However, additional assessments could refine the understanding of exercise pleasurable experience. Results also suggest that exercisers with distinct profiles of preference/tolerance depicted differentiated patterns for the affective response, possibly justifying a distinct approach when promoting affective regulation.
- The Co-Occurrence of Satisfaction and Frustration of Basic Psychological Needs and Its Relationship with Exercisers' MotivationPublication . Rodrigues, Filipe; Macedo, Rita; Teixeira, Diogo Santos; Cid, Luis; Travassos, Bruno; Neiva, Henrique P.; 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.
- The Physical Activity Enjoyment Scale (Paces) as a Two-Dimensional Scale: Exploratory and Invariance AnalysisPublication . Rodrigues, Filipe; Forte, Pedro; Teixeira, Diogo Santos; Cid, Luis; Monteiro, DiogoThe current study aims to examine the Physical Activity Enjoyment Scale (PACES) as a two-dimensional scale assessing two correlated but distinct dimensions of enjoyment. In total, 277 individuals (female = 108) aged between 18 and 53 years (M = 35.66; SD = 7.42) participated in the study. The unidimensional model solution displayed good fit. However, the exploratory structural equation modelling specification considering two correlated but distinct dimensions of enjoyment showed a better fit. This study was the first attempt to examine the possible existence of two dimensions within the eight-item PACES measure. The distinct aspect of the current research is to emphasize the complex and constant process of instrument validation. Scales should be viewed as a continuous process, and future methodological procedures will increase our understanding of instrument examination with more innovative statistical approaches.
