An integrated mindfulness and acceptance-based program for young elite female basketball players: Exploratory study of how it works and for whom it works best

In order to better understand how an integrated mindfulness and acceptance-based intervention works and for whom it works best, study objectives were to examine (i) the trajectories of mindfulness skills and performance-related outcomes during the intervention, and athletes’ perceptions of the impact of the intervention; and (ii) the potential moderating effects of personality characteristics on changes in targeted variables associated with the intervention. The sample consisted of 40 young elite female basketball players (M = 16.33, SD = 0.75 years) from three incoming groups at the French Federal Basketball Center over a 3-year period. All players participated in a 15-week Mindfulness BasketBall Integrated program. They completed online questionnaires measuring personality traits 10 months before the intervention, as well as pre-, mid- and post-intervention measurements of mindfulness skills, intensity and directional interpretation of stress, and performance satisfaction. They also participated in semi-structured social validation interviews conducted one month after the intervention. The results of the multilevel growth curve (MGCA) and thematic analyses revealed how the mindfulness skills and performance-related outcomes evolved over the course of the intervention and how these changes were perceived by the athletes. Specifically, the MGCA showed significant linear increases in acceptance, positive stress direction, and performance satisfaction. The complementary social validation data indicated perceived improvements in mindfulness skills and performance. The MGCA also showed that baseline personality traits moderated the effects of the program on acceptance and experience of stress. These findings may be used to inform the design of more effective integrated mindfulness and acceptance-based interventions.     

Examining the roles of experiential avoidance and cognitive fusion on the effects from mindfulness to athlete burnout: A longitudinal study

ObjectivesAthlete burnout is a maladaptive outcome that is potentially detrimental for performance and wellbeing. Cross-sectional evidence suggests that mindfulness might be associated with athlete burnout via experiential avoidance and cognitive fusion. In the current study, we extend knowledge of these hypothesized mediational pathways using a longitudinal design.MethodsData was collected at three occasions with a three-month interval. A final sample of 280 elite Chinese athletes aged 15–32 years (M_age = 19.13; SD = 2.92; Female = 130) reported their mindfulness at Time 1, experiential avoidance and cognitive fusion at Time 2, and athlete burnout at Time 3. Structural equation modelling was adopted to examine the mediating roles of experiential avoidance and cognitive fusion on the effects from mindfulness to athlete burnout.ResultsWe found statistically meaningful directs effects from mindfulness (Time 1) to experiential avoidance and cognitive fusion (Time 2), which in turn influenced athlete burnout (Time 3). However, the direct effect from mindfulness at Time 1 to athlete burnout at Time 3 was non-significant. The indirect effects of experiential avoidance and cognitive fusion on the effects from mindfulness to athlete burnout were significant, providing longitudinal evidence that these two variables contribute meaningfully to the mindfulness-burnout pathway.ConclusionWith initial evidence for the mediating effects of experiential avoidance and cognitive fusion, future studies could consider using experimental designs to examine the potential changing mechanisms of mindfulness on reducing athlete burnout.     

The effects of an authentic coaching intervention on athlete outcomes: A pilot randomised controlled trial

ObjectivesAuthentic leadership has been found to be related to promising outcomes in sport. However, no intervention designed to increase coaches' authentic leadership exists. The aim of this study was to develop and evaluate such an intervention.DesignThe study was a pilot randomised controlled trial. We used a mixed design with Group (Intervention, Control) as between- and Time (pre, post) as within-participants factors.MethodA total of 18 coaches (M_age = 37.89; 83% males) and their athletes (N = 153; M_age = 20.48; 50.3% females) were randomly allocated, via block randomisation, into either an intervention (coaches n = 9, athletes n = 90) or a control group (coaches n = 9, athletes n = 63). The coaches in the intervention group received a 2-h-long workshop and completed weekly coaching logs. Data were collected via questionnaires, which were administered to both the coaches and their athletes prior to the workshop and two months after the workshop.ResultsThe results revealed that the intervention group reported higher authentic leadership compared to the control group. A mixed-design analysis of variance indicated that athletes in the intervention group reported significantly higher enjoyment and prosocial behaviour from pre- to post-intervention compared to the control group.ConclusionsThe findings suggest that an authentic coaching intervention can be effective in improving coaches' authentic behaviours and promoting positive athlete outcomes.     

The effects of mindfulness training on beginners' skill acquisition in dart throwing: A randomized controlled trial

ObjectivesThe present study was into whether or not mindfulness training, based on the mindfulness-acceptance-commitment approach (MAC), can improve beginners' skill acquisition of dart throwing.DesignRandomised controlled trial.MethodsA total of 43 first-year college students who had not played darts professionally prior to the study were randomly assigned to either an attention control group (n = 21) or a mindfulness training group (n = 22) during an eight-week dart training program. Dart throwing and psychological variables were assessed at pre-intervention, post-intervention, and two-week follow-up.ResultsTwo-way repeated measures ANOVA revealed that the mindfulness group, but not the attention control group had significant improvements in mindfulness, experiential acceptance, and flow at post-intervention and follow-up. Although both groups improved dart throwing performance after the intervention, the improvement of the mindfulness group was statistically higher in comparison to that of the attention control group.ConclusionsIt was concluded that the MAC approach could improve the performance and adaptive sport experience of beginners in dart throwing.     

I act,therefore I am: Athletic identity and the health action process approach predict sport participation among individuals with acquired physical disabilities

ObjectiveThe study had two objectives 1) to test the fit of the Health Action Process Approach (HAPA) model for sport participation among individuals with acquired physical disabilities and 2) to estimate the extent to which athletic identity predicts intentions to engage in sport within the context of HAPA.DesignProspective cohort of 82 women and 19 men with acquired permanent disabilities (M_age = 44.0; M_{years post-injury} = 16.2; %_{in sport} = 61.7%).MethodAll HAPA indicators and athletic identity were assessed at baseline and sport participation was assessed using the Leisure Time Physical Activity Questionnaire for People with Spinal Cord Injury two weeks later. Structural equation modelling was used to test the HAPA model.ResultsThe HAPA constructs explained 15% of the variance in sport participation and 18% of the variance when athletic identity was added to the model. Instrumental (β = .21), affective (β = .15), and negative outcome expectancies (β = ?.20) were significant predictors of intentions to participate in sport, as was athletic identity (β = .25). Intentions to participate in sport significantly predicted planning (β = .54) yet there was no direct relationship between planning and sport participation (β = ?.008; p > .05). When the relationship between planning and maintenance self-efficacy was reversed, planning had a significant indirect effect on sport participation through maintenance self-efficacy (β = .33).ConclusionThe HAPA model is a good predictive model for sport participation among those with acquired physical disabilities; furthermore, athletic identity accounts for additional variance in sport participation. These constructs can be valuable components of sport promotion programs for this population.     

Development and preliminary validation of the mindfulness inventory for sport

ObjectivesDespite the increasing prevalence of mindfulness-based interventions in sport, no context-specific instrument currently exists to measure mindfulness in sport. The Mindfulness Inventory for Sport (MIS) was devised using a three-stage approach, to measure one's ability to: (1) be aware of disruptive stimuli and their associated internal reactions; (2) adopt a non-judgmental attitude towards these stimuli and reactions; and (3) quickly refocus attention on goal-related cues.MethodIn stage 1, a pool of items was developed and assessed by six experts in the areas of mindfulness and instrument validation. In stage 2, exploratory factor analyses with data collected from undergraduate student-athletes (N = 370) resulted in a three-factor, 19-item version of the instrument. In stage 3, confirmatory analyses using structural equation modelling were conducted with a sample of elite athletes (N = 343).Results and conclusionA final 15-item three-factor version displayed an acceptable model fit, with little evidence of invariance demonstrated across sport type and partial invariance across gender. In addition, the subscales of the MIS displayed significant correlations with conceptually-related variables such as flow, worry, concentration disruption, and perfectionism.     

Sources of autonomy support,subjective vitality and physical activity behaviour associated with participation in a lunchtime walking intervention for physically inactive adults

ObjectivesBased on Basic Needs Theory (BNT: Deci & Ryan, 1985), this study examined longitudinal relationships between autonomy support from two sources, psychological need satisfaction, subjective vitality and self-reported physical activity during a walking intervention for physically inactive adults. We proposed that autonomy support provided via a walk leader and the overall programme would independently predict change in subjective vitality and physical activity from baseline to week 16 (post-intervention) and at four month follow-up. Further, we proposed that direct relationships among sources of autonomy support and outcomes would be mediated by autonomy, relatedness, and competence need satisfaction.DesignA longitudinal examination.MethodsParticipants (N = 69; n = 63 females, n = 6 males) from a 16-week walking programme completed a multi-section questionnaire measuring the aforementioned variables at three time points, including a four month post-intervention follow-up.ResultsBoth hypotheses were partly supported. Autonomy support from the walk leader positively predicted changes in subjective vitality from baseline to week 16 and in physical activity from baseline to follow-up. Autonomy support from the programme positively predicted changes in subjective vitality from baseline to week 16. Finally, autonomy gained from the walk leader mediated the relationship between autonomy support and subjective vitality, and between perceived autonomy support and physical activity.ConclusionsFindings indicate that autonomy support from both a walk leader and wider programme can predict psychological need satisfaction, subjective vitality and physical activity. Clinicians and researchers implementing future walking interventions may increase physical activity and subjective vitality by facilitating psychological need satisfaction through autonomy support from both sources.     

The relationship between peer servant leadership,social identity,and team cohesion in intercollegiate athletics

Servant leadership is characterized by a leader’s emphasis on serving their followers first. Within the sport context, servant leadership has been studied primarily in coaches and has been associated with positive athlete outcomes, such as increased athlete satisfaction, motivation, and performance. However, the impact of servant leadership from an athlete perspective (e.g., formal team captains) has been underexplored. As such, the purpose of the present study was to examine the relationships between peer servant leadership, cohesion, and social identity within intercollegiate athletes. Two hundred and eighty-eight Division I and Division III NCAA intercollegiate athletes participated in the present study (female n = 165; male n = 123; M_age = 19.41, SD_age = 1.09) and completed the Revised Servant Leadership Profile for Sport (RSLP-S; Hammermeister et al., 2008), Group Environment Questionnaire (GEQ; Carron et al., 1985; Eys et al., 2007), and Social Identity Questionnaire for Sport (SIQS; Bruner & Benson, 2018). Structural equation modeling was used to assess the relationships between peer servant leadership, cohesion, and social identity. Results revealed that peer servant leadership positively predicted cohesion, and this relationship was fully mediated by social identity. The current study supports the effectiveness of peer servant leadership in sport contexts and provides theoretical support for the social identity approach to leadership.     

Self-compassion and body-related self-conscious emotions: Examining within- and between-person variation among adolescent girls in sport

ObjectivesSelf-compassion protects against the occurrence of negative body image experiences and may be particularly useful in defending against negative body- and appearance-related self-conscious emotions in sport. The aim of this study was to examine within- and between-person associations between self-compassion and appearance-related self-conscious emotions.Design & MethodIn a three-year longitudinal cohort study, adolescent girls involved in organized sport (N = 518, M_age = 14.02 ± 1.38) completed yearly self-reports of self-compassion, body- and appearance-related shame, guilt, embarrassment, and envy.ResultsBased on findings from multilevel models, higher levels of both average and time-varying self-compassion were associated with lower levels of body-related shame, guilt, embarrassment, and envy. Specifically, girls reported lower levels of negatively valanced self-conscious emotions when self-compassion was higher than usual.ConclusionsThese findings support previous accounts on the utility of self-compassion as a buffer against negative body image experiences and extend these findings to appearance-related self-conscious emotions in the sport context. In light of the declining levels of self-compassion for girls in adolescence, it is important to focus intervention efforts on cultivating self-compassion to protect girls from negative body-related emotional experiences in sport.     

Development and initial validity of the Exercise-Related Cognitive Errors Questionnaire

ObjectiveCognitive errors (CEs) reflect individuals' biased evaluations of context-relevant information. In the exercise domain, a valid form of exercise CE assessment is needed. The Exercise-related Cognitive Errors Questionnaire (E-CEQ) was developed to determine to what extent adults make cognitive errors regarding exercise decisions. The purpose of this study was to develop and provide initial validity evidence for the E-CEQ.DesignThe current study used an online self-report survey.MethodFirst, 24 initial vignettes representing 6 CEs were created and content validated. Second, data from 364 adults (M_age = 29.1, SD_age = 11.6; 81.3% female) was gathered to examine the E-CEQ's factor structure. Finally, data from the 364 participants was used to examine aspects of criterion-related validity.ResultsA 16-item, three-factor model was retained as the final E-CEQ factor structure and had good psychometric properties (χ² = 164.35, df = 75, p < .001; RMSEA = .057; CFI = .947; TLI = .915). Evidence of the questionnaire's predictive utility is provided. For example, exercise CEs were negatively related to exercise and accounted for 4.9% of additional variance beyond the contribution of past exercise in predicting exercise intention.ConclusionsThe steps taken to examine different forms of validity helped provide a platform from which to continue (a) to study biases linked to cognitive errors and (b) the E-CEQ validation process through ongoing investigation.     

Reciprocal relations between autonomous motivation from self-determination theory and social cognition constructs from the theory of planned behavior: A cross-lagged panel design in sport injury prevention

ObjectivesThe present study examined reciprocal relations between autonomous motivation from self-determination theory (SDT) and constructs from the theory of planned behavior (TPB) in a sport injury context.MethodsThe study adopted a three-wave longitudinal cross-lagged panel design. Physical education students in China (N = 4414; M_age = 14.42, SD = 1.75) completed self-report measures of autonomous motivation, attitude, subjective norm, and perceived behavioral control with respect to sport injury prevention at baseline (T1) and at two follow-up occasions one (T2) and three (T3) months later. Proposed reciprocal relations between autonomous motivation and the TPB constructs controlling for construct stability over time were tested using structural equation modeling.ResultsThree cross-lagged SEMs for effects of constructs measured at T1 on constructs measured at T2 and T3, and effects of constructs measured at T2 on constructs measured at T3 met goodness-of-fit criteria (CFI > 0.95, TLI > 0.94, RMSEA = 0.03, SRMR = 0.05) with consistent patterns of effects. Across the three models, autonomous motivation predicted the prospectively-measured TPB constructs with small-to-medium effect sizes (β range = 0.17 to 0.32, ps < .001), but associations between the TPB variables and prospectively-measured autonomous motivation were markedly smaller in size (β range = 0.01 to 0.18, ps range = .001 to .892).ConclusionsFindings provide initial support for the temporal ordering of the constructs in the integrated model of SDT and TPB in a sport injury context. Autonomous motivation from SDT is likely to be an antecedent of the constructs from the TPB.     

Mindfulness and positive affect: Cross-sectional,prospective intervention,and real-time relations

This study tested trait- and state-mindfulness and trait- and state-positive affect (PA) relations within a cross-sectional study (Study 1; N?=?174, 76% women, Mean (SD)_age?=?24 (2.7) years) and a randomized controlled 4-session mindfulness intervention study (Study 2; N?=?51, 65.4% women, Mean (SD)_age?=?25 (4.3) years). Study 1 : levels of trait-mindfulness and trait-like PA were related, as theorized, only among participants with meditation experience. Study 2 : Study 2 is a secondary analysis of a mindfulness intervention study [Tanay, Lotan, & Bernstein (2012). Salutary proximal processes and distal mood and anxiety vulnerability outcomes of mindfulness training: A Pilot preventive intervention. Behavior Therapy, 43, 492–505]. Unexpectedly, reduced levels of trait-like PA were observed pre- to post-intervention across conditions. No significant between-group mean differences were observed post-intervention. However, as expected, change in trait-mindfulness from pre- to post-intervention predicted change in trait-like PA among the intervention but not control condition. Second, levels of state-mindfulness during mindfulness meditation were positively related to levels of state-PA. The theoretical and applied implications of these findings for mindfulness and PA are discussed.     

The effect of self- and interpersonal emotion regulation on athletes’ anxiety and goal achievement in competition

ObjectivesThere exists a wealth of evidence that athletes must regulate their emotions for optimal performance and wellbeing. In addition to athletes’ attempts to regulate their own emotions, they may also attempt to regulate each other’s emotions (interpersonal emotion regulation). Though self- and interpersonal emotion regulation likely co-occur, previous research has not explored how these strategies concurrently impact athletes’ emotions and performance outcomes. In the current study, we examined whether athletes’ emotional self-regulation and the receipt of interpersonal emotion regulation from their teammates were related to their anxiety and goal achievement during competition.DesignQuantitative, cross-sectional retrospective survey design.MethodData were gathered following sport competitions from 509 participants from 50 interdependent sport teams from Canada and the UK (M_age = 19.0, SD = 3.1).ResultsAnalysis of the data using structural equation modeling revealed that after accounting for pre-competition anxiety, received interpersonal emotion regulation was not associated with anxiety during competition, though affect-worsening self-regulation was positively associated with anxiety during competition. Received interpersonal emotion regulation was also not associated with goal achievement, yet affect-improving and affect-worsening self-regulation were associated with goal achievement. Nevertheless, when the influence of emotional self-regulation on anxiety and goal achievement was set to zero, affect-improving and affect-worsening interpersonal emotion regulation were associated with anxiety during competition and affect-improving interpersonal emotion regulation was associated with goal achievement.ConclusionsThese data can be interpreted as evidence that emotion regulation actions between teammates are important for anxiety and performance outcomes, albeit this effect is attenuated in the presence of athletes’ own emotional self-regulation. These results extend the extant research on self- and interpersonal emotion regulation in sport, and in line with these observations, we highlight a number of future research opportunities for researchers examining emotion regulation in performance contexts.     

Macronutrient intake as a prospective predictor of depressive symptom severity: An exploratory study with adolescent elite athletes

BackgroundAppropriate availability of macro- and micronutrients has an important impact on cognitive performance, mood and mental health. Although the critical role of nutrition for elite athletes’ performance was recognized early on, little is known about whether consumption of specific macronutrients (carbohydrates, proteins, fat) predict the development of future depressive symptoms in adolescent elite athletes.MethodsParticipants were recruited from three Swiss Olympic Partner Schools (SOPS) in the Northwestern German speaking part of Switzerland. A total of 97 adolescent elite athletes (38% girls, M_age = 16.35 ± 1.19) participated in the study. Depressive symptoms (PHQ9) were assessed at baseline and after 10 months follow-up. A 3-day food recall was completed three months after the baseline assessment. Linear regression analyses were used to examine whether macronutrients predict depression symptom severity after controlling for covariates and baseline depressive symptoms.ResultsHigher protein consumption in athletes was a prospective predictor of lower depressive symptom severity at follow-up (β = −35, p < .05). Several deviations from recommended nutritional standards were observed in elite athletes.ConclusionsThe findings of this exploratory study support the notion that dietary behaviour may be prospectively associated with athletes’ mental health. However, more research is required with larger samples and more in-depth assessment techniques. Future research should also examine whether nutrition education and dietary modification can be used to prevent depressive symptoms among adolescent elite athletes.     

Group dynamics in Canadian recreational team sports later in life

As interest and participation in physical activity later in life increases, evidence is needed to inform the promotion, design, and delivery of community-based sport for older people. One important consideration is the dynamics of the group, which may influence experiences of team sport among aging populations. A qualitative study was undertaken to explore group dynamics concepts and perceived outcomes experienced by older adults involved in Canadian community-based recreational teams. Seventeen mid-life and older adults (M_age = 64.06, SD = 6.40) who previously participated in youth team sport and were currently involved in adult recreational team sport participated in semi-structured phone interviews. Results were organized into categories outlined in the conceptual framework for the study of sport teams (Eys et al., 2020). Issues specific to team dynamics experienced in older adulthood are highlighted and relate to competitiveness, sport specific skills/knowledge, competitive level, motivational climate, interdependence, team stability, group norms, roles, cohesion, leadership, social support, conflict, enjoyment, personal development, and social connections. Findings underscore the relevance of team dynamics in older adulthood and importance of understanding individual and environmental attributes in relation to group processes, structures, emergent states, and outcomes specific to sport for older adults. Directions for future research and practical implications to encourage greater involvement and sustained participation in team sport throughout the lifespan are discussed.     

Follow the leader: Identity leadership and moral behaviour in social situations among youth sport teammates

ObjectivesAlthough social identity has been linked to moral behaviour in past research, we know less about how the identity-enhancing behaviours of athlete leaders may relate to the experience of prosocial and antisocial behaviour between youth sport teammates. This study examined the relations between perceptions of athlete identity leadership and moral behaviour in social situations outside of training and competition.MethodsParticipants were 130 competitive male and female youth ice hockey players (M_age = 13.45 years, SD = 1.82, range = 10–17) from nine teams in a Northeastern Ontario city in Canada. Measures of identity leadership and moral behaviour were completed concurrently within the final three weeks of the regular season.ResultsUsing structural equation modeling, results demonstrated a significant positive association between identity leadership and both engaging in prosocial behaviour toward teammates (β = .37, p = .003) and receiving prosocial behaviour from teammates (β = 0.40, p < .006), accounting for 34% and 51% of the variance in each prosocial outcome, respectively. Although the relations with antisocial behaviour (engaged and received) were in the expected negative direction, the path estimates were not significant (ps > .23).ConclusionThese findings further our understanding of identity leadership in youth sport generally, offering insight into the relations between identity-enhancing athlete leader behaviours and moral behaviour. The findings also extend past moral behaviour research to consider the social situations in which teammates find themselves outside of training and competition.     

The effects of open vs. specific goals on flow and clutch states in a cognitive task

ObjectivesRecent qualitative evidence suggests that two optimal psychological states (flow and clutch) underlie excellent performance in sport. That research further suggests that the type of goal pursued influences which state is experienced. This study aimed to examine the effects of goal types (i.e., open, specific, and do-your-best goals) on flow and clutch states during performance in a cognitive task, which was developed and has been used in sport. Secondary aims were to investigate the effects of goal types on objective and subjective performance, confidence, and perceived challenge.DesignThis study employed a repeated measure design (mixed model).MethodParticipants (N = 95; M_age = 24.89, SD = 9.27) were randomised to one of three goal conditions and asked to perform a Letter and Number Identification Task, which was repeated for six attempts.ResultsParticipants prescribed open or do-your-best goals experienced significantly higher levels of flow than those prescribed specific goals, who conversely experienced significantly higher levels of clutch states. Participants assigned specific goals performed significantly better than those prescribed open or do-your-best goals. Those assigned open or do-your-best-goals reported greater perceived performance, higher confidence, and feeling more optimally challenged.ConclusionsThese findings provide experimental support for the role of goal types in determining flow and clutch states, and further understanding of the psychological effects of these goal types. Implications are discussed, and recommendations are made for future research into the role of goals in experiencing flow and clutch states in sport and exercise.     

Intrinsic motivation and individual deliberate practice are reciprocally related: Evidence from a longitudinal study of adolescent team sport athletes

ObjectiveThere is limited understanding of how sport motivation is associated with deliberate practice in youth team sport athletes. Therefore, the aim of this study was to examine prospective associations between intrinsic motivation and individual deliberate practice in specializing team sport athletes.DesignLongitudinal.MethodEstonian adolescent team sport athletes (N = 163; M_age – 13.6 years at the beginning of study) completed the Sport Motivation Scale and training diary across a 12-month period.ResultsBoth individual deliberate practice and intrinsic motivation increased over the 1-year period. Greater baseline intrinsic motivation predicted subsequent individual deliberate practice and greater initial individual deliberate practice predicted greater subsequent intrinsic motivation. The bidirectional relationship between athletes intrinsic motivation and individual deliberate practice were replicated across both time lags.ConclusionThe findings have significant implications for the importance placed on intrinsic motivation as a means of increasing of individual deliberate practice as well being an important outcome variable in specializing team sport athletes.
