Background: Grounded in Self-Determination Theory (SDT) and the Dualistic Model (DM) of Passion, this study examined the motivational mechanisms underlying psychological well-being among Tunisian physical education teachers. The objectives were twofold: to examine validity evidence of the Arabic version of the Basic Psychological Need Satisfaction and Frustration Scale (BPNSFS) and to test an integrative structural model linking harmonious passion, need satisfaction and frustration, well-being, vitality, happiness, and perceived stress. Methods: A representative sample of physical education teachers (1238) completed standardized instruments to assess passion, basic psychological needs, and well-being. To conduct exploratory and confirmatory factor analyses, the group was randomly divided into two independent subgroups. Reliability and validity were assessed using additional psychometric indicators, and a structural equation model was used to test the hypothesized relationships. Results: The results support the multidimensional structure and psychometric validity of the scale in the Tunisian context. Harmonious passion appears to be a positive factor in the satisfaction of psychological needs and a negative factor in cases of frustration. The satisfaction of these needs is closely linked to a high level of well-being, whereas their dissatisfaction is associated with adverse consequences. Well-being is also associated with increased vitality, greater happiness, and reduced stress, reflecting adaptive psychological functioning. Conclusions: Harmonious passion and basic psychological need satisfaction emerge as central resources for sustaining teacher well-being, vitality, and resilience against stress in educational contexts.

This study investigated the long-term cardiovascular effects of coronavirus disease (COVID-19) in elite male athletes by comparing the heart rate variability (HRV), arterial stiffness, and other cardiovascular parameters between those with and without prior COVID-19 infection. Methods: This cross-sectional study evaluated 120 elite male athletes (60 post COVID-19, 60 controls) using anthropometric measurements, body composition analysis, pulmonary function tests, HRV analysis, arterial stiffness assessments, hemodynamic monitoring, and microcirculatory function tests. Results: Athletes post COVID-19 showed significantly higher lean mass (p = 0.007), forced vital capacity (p = 0.001), and forced expiratory volume in 1 s (p = 0.007) than controls. HRV parameters did not significantly differ between the groups. Post-COVID-19 athletes exhibited peripheral vascular resistance (p = 0.048) and reflection index (p = 0.038). No significant differences were observed in the blood pressure, cardiac output, oxygen saturation, or microcirculatory oxygen absorption. Conclusions: Elite male athletes showed notable cardiovascular resilience after COVID-19, with only minor differences in vascular function. The maintained cardiac autonomic function and improved lung parameters in post-COVID-19 athletes suggests an adaptive response. These findings support the cardiovascular health of elite athletes following COVID-19 but emphasize the importance of continued monitoring.

Background: Young adults face a convergence of academic, economic, and social pressures that elevates their risk for stress-related psychological disorders. Perceived stress encompasses two theoretically and empirically distinct components, perceived helplessness and perceived self-efficacy, but most research treats it as a single composite score, obscuring the differential mechanisms through which each dimension influences mental health. Aim: The study aimed to (i) quantify the direct effects of perceived helplessness and perceived self-efficacy on psychological distress, (ii) test insomnia and physical activity as concurrent mediators of each dimension’s indirect pathway to distress, and (iii) determine whether the two stress dimensions activate meaningfully distinct mechanisms. Methods: A cross-sectional study enrolled 1688 young adults aged 18–23 years (M = 18.76, SD = 1.01; 41.6% female) from higher education institutions in Tunisia. Participants completed Arabic-validated versions of the Perceived Stress Scale (PSS-10), Insomnia Severity Index (ISI), Depression Anxiety Stress Scales (DASS-21), and the International Physical Activity Questionnaire (IPAQ). Structural equation modeling (SEM) with unweighted least squares estimation and 5000 bootstrap resamples tested direct and indirect pathways. Results: Perceived helplessness exerted strong direct effects on psychological distress (beta = 0.25, p < 0.001) and substantial indirect effects through insomnia (beta = 0.21, p < 0.001) and physical activity (beta = 0.03, p < 0.001). Insomnia was the dominant mediator, showing the strongest bivariate association with distress (r = 0.58, p < 0.01). Perceived self-efficacy produced markedly weaker direct (beta = 0.06, p = 0.002) and indirect effects, a pattern that, like its other associations in the model, runs in the same positive direction as perceived helplessness rather than the inverse direction conventionally expected of a protective factor. Model fit was acceptable (CFI = 0.994, SRMR = 0.018, RMSEA = 0.076, the latter below the conventional 0.08 threshold). Conclusions: Stress management deficits are associated with psychological distress primarily through sleep disruption, consistent with a mediating role for insomnia in this cross-sectional sample. Physical activity provides a meaningful but secondary protective correlate. These findings offer a preliminary, hypothesis-generating basis for stratified, mechanism-based mental health interventions targeting sleep regulation and stress management in young adult populations, pending prospective confirmation.

Athlete burnout has been a real problem in the sport context. It has been defined as a syndrome that contains three dimensions: emotional and physical exhaustion, sport devaluation, and reduced sense of accomplishment. Thus, to assess burnout among Arab athletes, the need for a validated version of a suitable scale seems essential. The aim of this study was to validate an Arabic version of the Athlete Burnout Questionnaire (ABQ) and to assess its construct validity, reliability, and gender invariance. Following a rigorous cross-cultural adaptation process, 500 Tunisian handball players from 37 teams (298 males and 202 females) with ages ranging from 18 to 26 years (M = 22.67, SD = 3.64) participated in this study. The athletes were asked to fill in basic sociodemographic information and the Arabic version of the ABQ. Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were conducted to assess the factorial structure, reliability, sensitivity, and validity of the Arabic ABQ. The CFA revealed excellent fit indices (x2(46) = 147.152; x2/df = 1.98; p < 0.05; CFI = 0.984, TLI = 0.978, AGFI = 0.904, RMSEA = 0.057, GFI = 0.941) for the three-factor solution. Cronbach’s alpha showed high internal consistency for all three dimensions (Physical and Emotional Exhaustion (PEE) = 0.916; Devaluation of Sports Practice (DSP) = 0.982; Reduced Sense of Achievement (RSA) = 0.909). The results of the measurement invariance analysis of the A-ABQ scale demonstrated robust invariance between male and female athletes. The results of the Arabic version of the athlete burnout questionnaire proved that the scale is a valid and reliable tool for assessing burnout among Tunisian handball players, filling a critical gap in sport psychology resources for Arabic-speaking populations.
