The objective of the present research is to examine the factor structure of the Interpersonal Behavior Questionnaire (IBQ) and the Interpersonal Behavior Self Questionnaire (IBQ-Self) in the sport context. Confirmatory factor analyses were used to assess the psychometric properties and measurement invariance across sex and sports. For the IBQ, a sample of 813 Portuguese athletes aged between 15 and 32 years (M = 23.46; SD = 4.92) took part in this study. They had an average sports experience of approximately 7.62 ± 3.23 years. For the IBQ-Self, a sample of 606 Portuguese coaches aged between 20 and 73 years (M = 34.43; SD = 11.56) participated in this study. Both scales demonstrated good fit, achieved convergent and discriminant validity, exhibited acceptable internal consistency, and demonstrated invariance across sex and sports. Regarding the analysis of psychometric properties, the IBQ and IBQ-Self can be applied to Portuguese athletes and their coaches to measure perceived behaviors of others and self-reported behaviors.

This study aims to explore data on objectively measured physical activity from a sample of adults and older adults and to investigate the achievement of the minimum physical activity required for health benefits. Participants, 257 women (age 58.99 ± 18.93 years, BMI 26.75 ± 4.57 kg·m−2) and 178 men (age 49.22 ± 20.39 years, BMI 26.81 ± 3.51 kg·m−2), wore an accelerometer for 4 to 7 days. Approximately 40% of the time was spent daily in sedentary behaviors during waking hours. Our results do not sustain the suggestion that adult men are more physically active than women. The results indicated a decrease in intensity of physical activity with age, in men and women, but not in successive age groups. Around 75% of adults and 30% of older adults accumulated the minimum daily physical activity for health benefits, in periods shorter than 10 min, above moderate intensity. The number of steps taken per day revealed that most men and women (except the oldest) attained or exceeded the lower threshold for deriving health benefits. To obtain relevant health benefits, future physical activity interventions should aim at reversing the amount of sedentary behaviors, emphasizing increments in, at least, the lower levels of PA, and maintaining walking habits.

The aim of this study was to translate and validate the Basic Psychological Need Satisfaction and Frustration Scale for Portuguese exercisers. In addition, we sought to analyze gender invariance. We collected data from two independent samples of Portuguese respondents—a calibration sample with 316 participants and a validation sample with 632 participants. Results from confirmatory factor analysis supported the original six-factor model in both the calibration sample, χ2(237) = 471.814, χ2/ df = 1.99; B–S p <.001, Comparative Fit Index =.935, Tucker–Lewis Index =.924, standard mean root square residual =.047, root mean square error of approximation =.057 (90% confidence interval = [.050,.065]), and the validation sample, χ2(237) = 571.796, χ2/ df = 2.41; B–S p <.001, Comparative Fit Index =.948, Tucker–Lewis Index =.940, standard mean root square residual =.038, root mean square error of approximation =.047 (90% confidence interval = [.042,.052]). Moreover, our analysis revealed acceptable internal consistency, convergent and discriminant validity of the translated version, and invariance between the two samples and between genders, as differences across latent means showed that magnitude effects were trivial between samples and between male and female exercisers. These results support the use of the adapted scale among both male and female exercisers. [ABSTRACT FROM AUTHOR]

This study aimed to analyze measurement invariance of the Behavioral Regulation Sports Questionnaire (BRSQ) across gender and four different sports. In addition, we examined nomological validity via basic psychological needs satisfaction. Participants totaled 1,812 Portuguese athletes (1,220 males and 592 females; aged 15–59 years, Mage = 17.72, SD = 5.51) from football (n = 596), basketball (n = 273), swimming (n = 800), and parasport (n = 143). The BRSQ measurement model was invariant across gender and these four sports. The scale confirmed nomological validity in that satisfaction of basic psychological needs positively predicted autonomous forms of motivation and negatively predicted more controlled motivation and amotivation as suggested by self-determination theory. In light of this evidence for BRSQ construct validity, composite reliability, nomological validity, and invariance across gender and four different sports, this scale is a useful tool for coaches of the aforementioned sports in their efforts to evaluate their athletes' motivation.

The Multidimensional Daily Diary of Fatigue-Fibromyalgia-17 (MDF-fibro-17) is an instrument that measures the different components of fibromyalgia-related fatigue symptoms. The current study aims to examine the factor structure of the MDF-fibro-17 in a sample of Portuguese and Brazilian patients diagnosed with fibromyalgia. Additionally, a cross-cultural analysis was carried out on these samples to understand the multidimensional complexity of examining the different dimensions of fatigue in patients with different cultural backgrounds and how fibromyalgia impacts patients with this syndrome. A confirmatory factor analysis was performed to examine the psychometric properties of the measure. Additionally, a multigroup analysis was carried out on the samples of these two cultures to examine measurement invariance. In total, 209 Portuguese women aged between 21 and 75 years (M = 47.44; SD = 10.73) and 429 Brazilians women aged between 16 and 77 years (M = 46.51; SD = 9.24) participated in this study. The results revealed that the measurement model provided an acceptable fit to the data in both the Portuguese and Brazilian samples, also displaying acceptable convergent and discriminant validity. In addition, the model showed acceptable internal consistency and was invariant between cultures. In sum, the MDF-fibro-17 is a valid measure that offers a unique assessment of fatigue symptoms in Portuguese and Brazilian women with fibromyalgia. [ABSTRACT FROM AUTHOR]

Abstract: Objectives: The present study examined the extent to which scores from the Basic Psychological Needs in Exercise Scale are measurement invariant across Greek, Spanish, Portuguese, and Turkish samples of exercise participants. Design: A cross-sectional design wherein responses were analyzed from 504 Greek participants, 518 Spanish participants, 989 Portuguese participants, and 686 Turkish participants. Methods: Data on exercise participants' need satisfaction were collected using the Basic Psychological Needs in Exercise Scale (Vlachopoulos & Michailidou, 2006) after back translation for the languages involved in the study. Results: Multi-sample confirmatory factor analyses showed that BPNES scores were largely invariant at the configural, metric, and strong invariance levels, but not at the strict invariance level for Spanish, Portuguese, and Turkish samples compared to the Greek sample. Portuguese participants reported higher levels of satisfaction for all three needs compared to Greek participants, while for Spanish participants this was the case only for competence and relatedness. Turkish participants did not differ from Greek participants. Conclusions: The present findings support valid cross-cultural comparisons at the latent variance/covariance level and the latent/observed mean level of the constructs of autonomy, competence, and relatedness using the BPNES.

This study aims to validate the Portuguese version of the Satisfaction with Life Scale (Cronbach's alpha = 0.82) and the Positive and Negative Affect Scale (Cronbach's alpha = 0.86 for positive affect and 0.89 for negative affect) for people with disabilities and to examine the association between engaging in physical activity and affective responses, investigating the relationship with satisfaction with life. 143 Portuguese with disabilities filled in the Portuguese version of the scales. The findings endorsed the single factorial structure and reliability of the Satisfaction with Life Scale [χ2/df = 6.3, B-S p = 0.487, TLI = 0.989, CFI = 0.995, SRMR = 0.0263, RMSEA = 0.043 (CI = 0, 0.130)]. For Positive and Negative Affect Scale, the results also confirmed the factorial structure and reliability [χ2/df = 1.871, B-S p = 0.114, TLI = 0.891, CFI = 0.918, SRMR = 0.0778, RMSEA = 0.078 (CI = 0.048, 0.108)]. On the other hand, the structural model presented satisfactory fit to the data [χ2/df = 1.436, B-S p = 0.269, TLI = 0.917, CFI = 0.930, SRMR = 0.0748, RMSEA = 0.055 (CI = 0.033, 0.075)]. Significant direct effects have been found, as has been theoretically proposed, namely: years of practice displayed a positive and significant association with positive affect; positive affect was positively associated with satisfaction with life (β = 0.073, CI = 0.020, 0.139; p = 0.031)., Competing Interests: Declarations.

Teacher-endorsed supporting behaviors present themselves as key influencers of student adaptive academic and social functions. The objective of this paper was twofold. First, this study sought to test a model in which student-perceived autonomy support was associated with group cohesion, considering the mediating role of basic psychological needs satisfaction and intrinsic motivation. Second, the current study examined the dimensionality of the model across five Western countries, namely Spain, Portugal, Brazil, Chile, and Mexico. A convenience sample of 3033 college students ( M age = 21.51 ± SD = 3.71) were recruited for the analysis. The results revealed that perceived autonomy support was positively associated with needs satisfaction, being consequently associated with intrinsic motivation and, ultimately, with group cohesion. Additionally, a multigroup analysis revealed that the model was invariant across college students from the different countries. The current results are discussed around the promotion of teacher uses of autonomy-supportive behaviors fostering adaptive outcomes in students regarding positive social relations and that the cultures of Ibero-American countries are equivalent in this process., Competing Interests: The authors declare no conflicts of interest.
