The goals of this study were: (a) to explore the most effective approach to represent the factor structure of SEQ scores by employing advanced methodological techniques recently introduced in the scientific literature, including bi-factor, exploratory structural equation modelling (ESEM) and bi-factor ESEM; and (b) to examine the temporal invariance of SEQ scores using the best-fitting model previously identified. 460 athletes completed the SEQ across three measurement times to assess their emotional states experienced during competitions. Data were analyzed with a series of confirmatory factorial analysis, bi-factor, ESEM and bi-factor-ESEM. Considering the fit indices and standardized factor loadings across the three measurement points, the results indicated that ESEM could be regarded as the most suitable model for describing the factorial structure of SEQ scores. Furthermore, the findings provided evidence for the partial factor mean longitudinal invariance of SEQ. Finally, we hope these results will encourage research on longitudinal evolution of emotions across a season of sports competitions or over several seasons.

The aim of the study was to identify distinct trajectories of perceived stress and control in athletes across a season of sports competitions and whether these trajectory memberships could be predicted by subdimensions of the emotional intelligence (EI). Latent class growth analyses were performed on a five-stage longitudinal measurement plan (to cover the entire sporting season). Four hundred fifteen athletes answered to the Brief Emotional Intelligence Scale, the Mastery Scale, the Perceived Stress Scale, and the Attainment of Sport Achievement Goal Scale. The analyses revealed two trajectories of perceived stress (one trajectory adapted and one maladapted to performance) and two trajectories of perceived control (one trajectory adapted and one maladapted to performance). Moreover, athletes with higher emotional intelligence emotion regulation scores belong significantly more to performance-adaptive trajectories. The obtained results could contribute to the advancement of emotional intelligence intervention programs to optimize the dynamics of perceived stress and control within the sporting season.

Purpose: Study on the effect of psychological skills training on self-esteem (SE) in young athletes. Method: 10 swimmers and 35 volleyball players, split into an intervention group (25) and a control group (18). The intervention entailed a 3-week psychological skills training program covering arousal management, breathing, relaxation, mental imagery, and self-talk. Multilevel growth curve analyses evaluated SE changes. Results: The intervention group showed significant improvements in multiple SE dimensions—physical self-worth, fitness, athletic competence, strength, and body attractiveness but not general SE. Conclusions: This study provides initial evidence of a multimodal psychological skills training’s effectiveness in enhancing young athletes’ domain-specific SE. It highlights the role of domain-specific SE in young athletes’ well-being. Future research should examine psychological and physiological correlations and assess the long-term SE development in adolescent athletes.

Space analog research has increased over the last few years with new analogs appearing every year. Research in this field is very important for future real mission planning, selection and training of astronauts. Analog environments offer specific characteristics that resemble to some extent the environment of a real space mission. These analog environments are especially interesting from the psychological point of view since they allow the investigation of mental and social variables in very similar conditions to those occurring during real space missions. Analog missions also represent an opportunity to test operational work and obtain information on which combination of processes and team dynamics are most optimal for completing specific aspects of the mission. A group of experts from a European Space Agency (ESA) funded topical team reviews the current situation of topic, potentialities, gaps, and recommendations for appropriate research. This review covers the different domains in space analog research including classification, main areas of behavioral health performance research in these environments and operational aspects. We also include at the end, a section with a list or tool of recommendations in the form of a checklist for the scientific community interested in doing research in this field. This checklist can be useful to maintain optimal standards of methodological and scientific quality, in addition to identifying topics and areas of special interest.

The aims of this study were: (a) to explore the relationships between adaptive defense mechanisms (ADMs), maladaptive defense mechanisms (MADMs), stress, recovery, resilience, and sport burnout; and (b) to examine resilience, stress, and recovery as mediators of the relationship between defense mechanisms and burnout. One hundred and seventy-five athletes (M = 20.30 years, SD = 3.75) completed self-report questionnaires assessing defense mechanisms, resilience, stress, and recovery. Correlation analysis revealed that MADMs were positively associated with burnout, while ADMs had no significant link with burnout. Concerning mediation analysis, results showed a mediating effect of resilience in the relationship between ADMs and burnout. The findings also demonstrated a mediating effect of resilience and recovery in the relationship between MADMs and burnout. Our study highlighted that certain defenses categorized as adaptive might not be suitable in specific situations, thus underscoring the influence of mediating variables. The findings of mediation analysis demonstrated that resilience appears to serve as a particularly protective factor against burnout. On the contrary, MADMs would have a deleterious influence in the management of stress, which could lead to burnout. Coaches may consider fostering athletes’ resilience in conjunction with ADMs and implementing targeted psychological exercises to reduce the use of MADMs.

This study examined the effect of a Slow-Paced Breath (i.e., 6 breaths per minute) without Biofeedback (SPB-NoHRVB) protocol on semi-elite adolescent swimmers’ psychological and physiological states during a seven-week ecological training period. A linear mixed-effects multilevel regression analysis approach was used with 13 adolescent national-level swimmers. Athletes were randomly assigned to an intervention group (n = 7) and a control group (n = 6). Seven waves of assessments were completed weekly during a seven-week training preparation in ecological conditions. During the protocol, swimmers completed subjective quantitative measures (RESTQ-36-R-Sport; cognitive perceived stress and control states about the training process, training subjective performance, and subjective internal training load) and physiological heart rate (HR) (HR of exercise, absolute and normalized HR recovery during the first 60 s of recovery; HRR60 and nHRR60) and heart rate variability (HRV) (MeanRR, RMSSD, LFnu and HFnu, LF/HF ration) tests (through a submaximal heart rate (5′-5′ test) once a week. Results revealed that the SPB-NoHRVB protocol significantly predicts biopsychosocial recovery states, cognitive perception of control, and training subjective performance (i.e., a significant effect of the SPB-NoHRVB protocol with the dependent variables simple time trajectories). However, no significant effects were found for biopsychosocial stress scales, cognitively perceived stress, HR, or HRV markers. Our results suggest that SPB-NoHRVB induces simple evolutions over time for crucial variables in athletes’ adaptation to the training process (i.e., cognitive appraisals and biopsychosocial states). In contrast, it highlights that SPB-NoHRVB does not induce better stress states. This specific effect on the resource component is an exciting result that will be discussed in the manuscript.

This study examined the effect of an asynchronous heart rate variability biofeedback (HRV-BFBasync) protocol on national-level adolescent swimmers’ cognitive appraisals and recovery-stress states during a six-week ecological training period. A polynomial mixed-effects multilevel regression analysis approach was used with 27 adolescent national-level swimmers randomly assigned to an intervention group (n = 14) and a control group (n = 13). Six waves of assessments of cognitive appraisals and recovery-stress states were completed during six weeks of training preparation in ecological conditions. The results revealed that the HRV-BFBasync protocol significantly predicts lower levels of biopsychosocial stress states and cognitive stress. However, no significant effects were found for biopsychosocial recovery scales and cognitive perceived control. The results suggested that total stress states, sport-specific stress, and cognitive perceived stress evolutions are a function of polynomial time third-degree interactions with HRV-BFB protocol. Overall, this study suggested that the HRV-BFBasync protocol leads adolescent athletes to experience lower biopsychosocial and cognitive stress levels during training periodization. Our results also suggest that HRV-BFB induces complex evolutions over time for stress and recovery states but does not have a predictive function for the recovery states and perceived control.

This study aimed to design and evaluate an emotional intelligence (EI) training program for adolescents involved in intensive sport training centers. A total of 31 young elite table-tennis players received EI training through six sessions and a recall period across a competitive season. The athletes completed (1) a self-reported questionnaire at the beginning and at the end of the program to assess intra-individual and inter-individual EI; and (2) a logbook twice a month during a period of 6 months including emotion regulation strategies (ERS), cognitive appraisals, and discrete emotions. The results highlighted an increased level of intra-individual EI, especially for understanding and regulation dimensions. Moreover, multilevel growth curve analyses (MGCAs) revealed adaptive changes for the reported levels of acceptance, refocus on planning, positive reappraisal, average less-adaptive ERS, self-blame, and catastrophizing strategies. These findings support a beneficial effect of the program on ERS. However, the analyses revealed limited results for discrete emotions. Finally, MGCAs also revealed adaptive trajectories in the scores of cognitive appraisals and thus provided further evidence of the benefits of the EI program on threat, challenge, and loss levels. In sum, this interventional study adds to a growing body of EI literature by proposing a theoretically based intervention for adolescents involved in a competitive and emotionally demanding environment. Lay summary: The emotional intelligence is now recognized as a crucial factor to success in competitive sport. It appears crucial to develop these competences among youth athletes which are exposed to various constraints. This study confirms that the emotional intelligence (as some emotion regulation strategies) can be improved with short and adapted interventions.
