Initial validation of the Portuguese version of the Interpersonal Behavior Questionnaire (IBQ & IBQ-Self) in the context of exercise: Measurement invariance and latent mean differences
Publication . Rodrigues, Filipe; Pelletier, Luc; Neiva, Henrique Pereira; Teixeira, Diogo Santos; Cid, Luis; Monteiro, Diogo
The aim of the present research is to examine the factor structure of the Interpersonal Behavior Questionnaire (IBQ), and the Interpersonal Behavior Questionnaire Self (IBQ-Self), two scales developed for the purpose of measuring supportive and thwarting interpersonal behaviors. Structural equation modeling was used to examine the psychometric proprieties, the nomological validity with the basic needs’ satisfaction and frustration as well as the measurement invariance between gender, and differences across latent means. For the IBQ, 837 Portuguese gym members aged between 18 to 63 years old (M = 34.58; SD = 11.35) participated in this study. They had been practicing physical exercise for about 43.00 ± 37.00 months. For IBQ-Self, 612 trainers, with a professional experience that ranged from 12 to 492 months (M = 88.54; SD = 77.89), participated in this study. The analysis revealed that both scales had good fit, achieving convergent and discriminant validity. In addition, they show acceptable internal consistency and invariance between gender. Nomological validity displayed projected results, according to theoretical and empirical literature. Regarding analysis of the psychometric proprieties, IBQ and IBQ-Self can be applied to Portuguese exercisers and exercise physiologist to measure perceived behaviors from others and self-reported behaviors, respectively.
Physical activity and affect of the elderly: Contribution to the validation of the Positive and Negative Affect Shedule (PANAS) in the Portuguese population
Publication . Antunes, Raul; Couto, Nuno; Vitorino, Anabela; Monteiro, Diogo; Marinho, Daniel
The concept of affect corresponds to the emotional dimension of subjective well-being (Diener, Emmons, Larsen, & Griffin, 1985). It is represented by two dimensions (negative affect and positive affect), which were the basis of the development of the Positive and Negative Affect Schedule - PANAS (Watson, Clark, & Tellegen, 1988). It was translated and validated for the Portuguese population by Galinha and Pais-Ribeiro (2005b). Nevertheless, because the Portuguese version was not validated in a sample of Portuguese elderly, the goals of this study consisted in the translation of the scale (PANAS) from the original version of 20 items and the validation of its measurement model (including a shortened version) for a sample of Portuguese elderly (n = 311), aged 60 years or older (M = 68.53; DP = 6.69); it was then tested by a confirmatory factorial analysis. The results demonstrated that the measurement model (two factors and 10 items) of the shortened Portuguese version of the PANAS presented acceptable psychometric qualities, which adjusted to the data in a satisfactory way (factorial weights ranging between .57 and .70 in positive affect and between .52 and .68 in negative affect). We also concluded that older adults who practice more physical activity perceive higher levels of positive affect F(2, 297) = 3,78, p < .05; η2 = .025, and lower levels of negative affect F (2, 297) = 6,24, p < .001; η2 = .040).

The aim of this study was to examine the effects of the motivational climate created by the coach and perceived by a group of young high-performance handball players on their sport motivation, self-determination, sport psychological needs and sport commitment. The study participants were 479 young handball players. The age range was 16-17 years old. Players were administered a battery composed of a Perceived Motivational Climate in Sport Questionnaire, Sport Motivation Scale, the Basic Psychological Needs in Exercise Scale and Sport Commitment Questionnaire to measure the above-mentioned theoretical constructs. Results showed that the handball players showed high levels of a task-involving climate, of basic psychological needs satisfaction and of self-determined motivation and commitment. Higher levels of basic psychological needs such as autonomy and competence were associated with a higher task-involving climate, self-determined index and sport commitment (task-involving climate-basic psychological needs (β = 0.55; 95% IC 0.387/0.682; p = 0.001); Ego-involving climate-basic psychological needs (β = 0.06; 95% IC -0.069/0.181; p = 0.387); Basic psychological needs-self-determined index (β = 0.48; 95% IC 0.376/0.571; p = 0.001); Self-determined index-commitment (β = 0.58; 95% IC 0.488/0.663; p = 0.001). The obtained model showed that basic psychological needs mediated the association between a task-involving climate and self-determination, and self-determination mediated the association between basic psychological needs satisfaction and commitment.
Sleep and Neurochemical Modulation by DZNep and GSK-J1: Potential Link With Histone Methylation Status

Histone methylation/demethylation plays an important modulatory role in chromatin restructuring, RNA transcription and is essential for controlling a plethora of biological processes. Due to many human diseases have been related to histone methylation/demethylation, several compounds such as 3-deazaneplanocin A (DZNep) or 3-((6-(4,5-Dihydro-1H-benzo[d]azepin-3(2H)-yl)-2-(pyridin-2-yl)pyrimidin-4-yl)amino)propanoic acid; N-[2-(2-pyridinyl)-6-(1,2,4,5-tetrahydro-3H-3-benzazepin-3-yl)-4-pyrimidinyl]-β-Alanine (GSK-J1), have been designed to inhibit histone methylase or suppress histone demethylase, respectively. In the present study, we investigated the effects on the sleep-wake cycle and sleep-related neurochemical levels after systemic injections of DZNep or GSK-J1 given during the light or dark phase in rats. DZNep dose-dependently (0.1, 1.0, or 10 mg/kg, i.p.) prolonged wakefulness (W) duration while decreased slow wave sleep (SWS) and rapid eye movement sleep (REMS) time spent during the lights-on period with no changes observed in dark phase. In opposite direction, GSK-J1 (0.1, 1.0, or 10 mg/kg, i.p.) injected at the beginning of the lights-on period induced no statistical changes in W, SWS, or REMS whereas if administered at darkness, we found a diminution in W and an enhancement in SWS and REMS. Finally, brain microdialysis experiments in freely moving animals were used to evaluate the effects of DZNep or GSK-J1 treatments on contents of sleep-related neurochemicals. The results showed that DZNep boosted extracellular levels of dopamine, norepinephrine, epinephrine, serotonin, adenosine, and acetylcholine if injected at the beginning of the lights-on period whereas GSK-J1 exerted similar outcomes but when administered at darkness. In summary, DZNep and GSK-J1 may control the sleep-wake cycle and sleep-related neurochemicals through histone methylation/demethylation activity.
Behavioral Regulation Sport Questionnaire: Gender and Sport Invariance in Portuguese Athletes
Publication . Monteiro, Diogo; Teixeira, Diogo; Vitorino, Anabela; Moutão, João; Rodrigues, Filipe; Machado, Sérgio; Cid, Luis
This study aimed to analyze measurement invariance of the Behavioral Regulation Sports Questionnaire (BRSQ) across the 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 ¼ 17.72, SD ¼ 5.51) from football (n ¼ 596), basketball (n ¼ 273),
swimming (n ¼ 800), and parasport (n ¼ 143). The BRSQ measurement model was
invariant across the gender and these four sports. The scale confirmed nomological validity in that satisfaction of the 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 the gender and four different sports, this scale is a useful tool for the coaches of the aforementioned sports in their efforts to evaluate their athletes’ motivation.
