Psychometric properties of the Talent Development Environment Questionnaire with Chinese talented athletes.

The development of talented athletes is a priority for many countries across the world, including China. A validated Chinese 5-factor Talent Development Environment Questionnaire (TDEQ-5) would go some way in helping researchers and practitioners investigate talent development systems within China from an evidence-based perspective. For this purpose, the 25-item English TDEQ-5 was translated to Chinese through a standardised process. The translated scale was then administered to 538 talented Chinese youth athletes. Confirmatory factor analysis revealed adequate model fit of the scale. The internal reliability, concurrent and discriminant validity, and test-retest reliability of the scale were adequately supported. The scale was also invariant across gender. It is recommended that the Chinese TDEQ-5 can be used with confidence in both applied and research settings.

The process by which perceived autonomy support predicts motivation, intention, and behavior for seasonal influenza prevention in Hong Kong older adults.

BACKGROUND: This study examined the effectiveness of a theoretical framework that integrates self-determination theory (SDT) and the theory of planned behavior (TPB) in explaining the use of facemasks to prevent seasonal influenza among Hong Kong older adults. METHODS: Data were collected at two time points in the winter in Hong Kong, during which influenza is most prevalent. At Time 1, older adults (N = 141) completed self-report measures of SDT (perceived autonomy support from senior center staff, autonomous motivation for influenza prevention) and TPB (attitude, subjective norm, perceived behavioral control, and intention for influenza prevention) constructs with respect to facemask used to prevent infection. Two weeks later, at Time 2, participants' acceptance of a facemask to prevent influenza in the presence of an experimenter with flu-like symptoms was recorded. RESULTS: Path analysis found that perceived autonomy support of senior center staff was positively and significantly linked to autonomous motivation for facemask use, which, in turn, was positively related to intentions to wear facemasks through the mediation of attitude, subjective norm, and perceived behavioral control. However, the effect of intention on facemask use was not significant. CONCLUSIONS: Results generally support the proposed framework and the findings of previous studies with respect to intention, but the non-significant intention-behavior relationship may warrant future research to examine the reasons for older adults not to wear facemasks to prevent seasonal influenza despite having positive intentions to do so.

Cross-Cultural Invariance of the Mental Toughness Inventory Among Australian, Chinese, and Malaysian Athletes: A Bayesian Estimation Approach.

The aims of this study were to assess the cross-cultural invariance of athletes' self-reports of mental toughness and to introduce and illustrate the application of approximate measurement invariance using Bayesian estimation for sport and exercise psychology scholars. Athletes from Australia (n = 353, Mage = 19.13, SD = 3.27, men = 161), China (n = 254, Mage = 17.82, SD = 2.28, men = 138), and Malaysia (n = 341, Mage = 19.13, SD = 3.27, men = 200) provided a cross-sectional snapshot of their mental toughness. The cross-cultural invariance of the mental toughness inventory in terms of (a) the factor structure (configural invariance), (b) factor loadings (metric invariance), and (c) item intercepts (scalar invariance) was tested using an approximate measurement framework with Bayesian estimation. Results indicated that approximate metric and scalar invariance was established. From a methodological standpoint, this study demonstrated the usefulness and flexibility of Bayesian estimation for single-sample and multigroup analyses of measurement instruments. Substantively, the current findings suggest that the measurement of mental toughness requires cultural adjustments to better capture the contextually salient (emic) aspects of this concept.

Psychometric properties of the Brunel Mood Scale in Chinese adolescents and adults.

Building on the work of Terry and colleagues (Terry, P. C., Lane, A. M., Lane, H. J., & Keohane, L. (1999). Development and validation of a mood measure for adolescents. Journal of Sports Sciences, 17, 861-872; Terry, P. C., Lane, A. M., & Fogarty, G. J. (2003). Construct validity of the Profile of Mood States-Adolescents for use with adults. Psychology of Sport & Exercise, 4, 125-139.), the present study examined the validity and internal consistency reliability of the Chinese version of the Brunel Mood Scale (BRUMS-C) among 2,548 participants, comprising adolescent athletes (n = 520), adult athletes (n = 434), adolescent students (n = 673), and adult students (n = 921). Both adolescent and adult athletes completed the BRUMS-C before, during, or after regular training and both adolescent and adult students completed the BRUMS-C in a classroom setting. Confirmatory factor analyses (CFAs) provided support for the factorial validity of a 23-item six-factor model, with one item removed from the hypothesised measurement model. Internal consistency reliabilities were satisfactory for all subscales across each of the four samples. Criterion validity was supported with strong relationships between the BRUMS-C, abbreviated POMS, and Chinese Affect Scale consistent with theoretical predictions. Multi-sample CFAs showed the BRUMS-C to be invariant at the configural, metric, strong, and structural levels for all samples. Furthermore, latent mean difference analyses showed that athletes reported significantly higher levels of fatigue than students while maintaining almost the same levels of vigour, and adolescent students reported significantly higher levels of depressed mood than the other three samples.

Mindfulness and acceptance-based training for elite adolescent athletes: a mixed-method exploratory study.

Objectives: This study aimed to examine the effectiveness of a specifically designed mindfulness-acceptance-insight-commitment (MAIC) training program on relevant psychological factors (i.e., mindfulness, acceptance, performance-related satisfaction) as well as sport training performance for elite adolescent athletes from Hong Kong. And it also aimed to explore the athletes' real experiences (i.e., receptiveness and perceptions) of completing the MAIC program. Methods and design: The mixed-method was used in this study, including a randomized controlled trial (RCT) and a qualitative exploration. The RCT employed a 2 (groups) x 3 (data collection points) design involving 40 elite adolescent athletes from the Hong Kong Sports Institute (HKSI). These athletes were randomly assigned to either the MAIC training group (MT; n = 20, Mage = 15.65) or the control group (CG; n = 20, Mage = 15.85) to further test the effectiveness of the MAIC intervention on mindfulness, acceptance, performance-related satisfaction, and sport training performance. Subsequent to the RCT, the qualitative exploration was used to explore the athletes' real experiences towards the MAIC program. In the qualitative exploration, all athletes who participated in the MAIC program were invited to participate in voluntary semi-structured interviews. Of these, 14 athletes chose to take part in the interviews. The RCT employed a 2×3 mixed-design ANOVA, while thematic analysis was applied to the qualitative exploration. Results: The results revealed that the MAIC training program significantly enhanced athletes' mindfulness, acceptance, satisfaction with performance, and sport training performance. However, these effects diminished at the follow-up assessment compared to post-training. Notably, the acceptance level of MT athletes did not significantly differ from CG athletes at the follow-up assessment. Additionally, the qualitative analysis identified four key dimensions: (a) Attitude towards MAIC training, (b) Reflection on the MAIC learning process, (c) Outcomes of MAIC training, and (d) Recommendations for future MAIC training. Overall, the qualitative findings complemented and reinforced the quantitative results, offering deeper insights into athletes' experiences and valuable suggestions for further enhancing the MAIC program. Conclusion: The findings suggested that the specifically designed MAIC training program in this study effectively enhanced sport training performance and various psychological factors among elite adolescent athletes from Hong Kong. Nevertheless, further investigations are still required to comprehensively evaluate and further develop the MAIC training program.

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

OBJECTIVES: Athlete 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. METHODS: Data was collected at three occasions with a three-month interval. A final sample of 280 elite Chinese athletes aged 15-32 years (Mage = 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. RESULTS: We 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. CONCLUSION: With 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.

Further Examination of the Psychometric Properties of the Multicomponent Mental Health Literacy Scale: Evidence from Chinese Elite Athletes.

This study aimed to examine the psychometric properties of the Multicomponent Mental Health Literacy Scale (MMHLS) among Chinese elite athletes. Particularly, the factorial validity, convergent validity, discriminant validity, concurrent validity, internal-consistency reliability, and test-retest reliability of the MMHLS were examined. A total of 320 participants were recruited from the Guangdong provincial sports training center in China. Data collection was conducted between 30 June and 31 July 2020 using electronic questionnaires. Confirmatory factor analysis (CFA), Rasch analysis, correlation analysis and independent-sample t-tests were conducted using Mplus 8.3 and ConQuest 2.0. The CFA results supported the factorial validity of the three-dimensional MMHLS, consisting of knowledge-oriented MHL, beliefs-oriented MHL, and resource-oriented MHL. Cronbach's alpha and composite reliability coefficients supported the internal-consistency reliability of the MMHLS. Moreover, the convergent and discriminant validities were supported for the subdimension of MHL-Knowledge, MHL-Beliefs, and MHL-Resources. Concurrent validity was demonstrated through correlations between MMHLS, help-seeking attitudes, and stigma. Rasch analysis provided further evidence of the psychometric quality of the instrument in terms of its dimensionality, item fit statistics, and rating scale effectiveness. Finally, test-retest reliability was 0.66 after one month. In conclusion, the 24-item three-dimensional MMHLS was verified to be a reliable and valid measurement of mental health literacy in Chinese elite athletes.

Effect of carbohydrate and protein solutions consumed during a moderate-intensity exercise on post-exercise appetite.

This study aimed to investigate whether co-ingestion of carbohydrate and protein during exercise affect the post-exercise ad libitum food intake. Twelve healthy active male participants (mean±SD, age: 20±1; height: 176±6cm; weight: 63.6±5.3kg; VO2peak: 51.2±7.1ml/kg/min) completed three main experimental trials in a randomized cross-over design. In each trial, the participants completed 1h of ergometer cycling at 60% VO2peak, followed by 2h recovery. The participants were required to consume one of three solutions every 15min during exercise: distilled water (DW), carbohydrate-electrolyte solution (CE), and carbohydrate-electrolyte-protein solution (CEP). The energy was matched between the two latter solutions. The CHO-to-protein ratio in CEP was 2:1. At the end of recovery period, participants were provided with pizza lunch ad libitum, and the amount consumed was recorded. Several subjective feelings, appetite scores and blood glucose were determined during the experimental trials. No differences were found in either the amount of consumed pizza (DW vs. CE vs. CEP: 607±128 vs. 592±119 vs. 599±125g, P=0.845) or the appetite score before pizza was consumed (DW vs. CE vs. CEP: 14±9 vs. 12±14 vs. 14±10, P=0.357) among the three trials. The blood glucose concentrations during exercise were higher in the CE and CEP trials than in the DW trial. In conclusion, different solutions consumed during a 1h moderate-intensity exercise in the present study did not affect post-exercise appetite.

Effect of protein and carbohydrate solutions on running performance and cognitive function in female recreational runners.

This study compared the effects of a carbohydrate-electrolyte-protein solution (CEPS, 2% protein plus 4% carbohydrate), carbohydrate-electrolyte solution (CES, 6% carbohydrate), and noncaloric sweetened placebo (PLA) on both 21-km running performance and cognitive function. Eleven female recreational endurance runners performed a 21-km time-trial running on three occasions, separated by at least 28 days. In a randomized cross-over design, they ingested CEPS, CES, or PLA at a rate of 150 mL every 2.5 km with no time feedback. A cognitive function test was performed before and after the run. Participants ingested approximately 24 g/h carbohydrate plus 12 g/h protein in CEPS trial, and 36 g/h carbohydrate in CES trial during each 21-km trial. Time to complete the time-trial was slightly shorter (P < 0.05) during CES (129.6 ± 8.8 min) than PLA (134.6 ± 11.5 min), with no differences between CEPS and the other two trials. The CEPS trial showed higher composite of visual motor speed than the PLA trial (P < 0.05). In conclusion, CES feedings might improve 21-km time-trial performance in female recreational runners compared with a PLA. However, adding protein to the CES provided no additional time-trial performance benefit. CEPS feeding during prolonged exercise could benefit visual motor speed compared to PLA alone, but no differences in the performance of the other cognitive function tests were found.

Assessing acceptance in mindfulness with direct-worded items: The development and initial validation of the Athlete Mindfulness Questionnaire.

PURPOSE: The purpose of the current study was to develop and validate a sport-specific mindfulness measure, the Athlete Mindfulness Questionnaire (AMQ), through 5 related studies using 4 separate samples of Chinese athletes. The AMQ is a 3-factor measure designed to assess mindfulness that reflects present-moment attention, awareness, and acceptance in a sport context. METHODS: In Study 1, an initial pool of items was generated based on previous literature, existing mindfulness scales, as well as interviews with and feedback from the athletes, coaches, and mindfulness experts. Initial support for the 3-factor structure of the AMQ was established via exploratory factor analysis in Study 2, and cross-validated through confirmatory factor analysis in Studies 3 and 4. In Study 5, a modified 3-factor AMQ with direct-worded acceptance items was examined in a fourth independent sample. RESULTS: Convergent and concurrent validities of the acceptance subscale failed to be established in Studies 3 and 4 which may be due to the inattention and confusion of the athletes whilst interpreting the reverse-worded items. A modified 16-item AMQ in Study 5 displayed satisfactory model fit and acceptable internal consistencies. Most importantly, convergent and concurrent validities of the 16-item AMQ were supported. The 3 subscales showed significant positive associations with mindfulness, flow, well-being, and positive affect and significant negative associations with experiential avoidance, burnout, and negative affect. CONCLUSION: The AMQ is a psychometrically sound measure of mindfulness in a sport context. The importance of using direct-worded acceptance items is discussed.

Transition to Adulthood: Relationships Among Psychosocial Correlates, Stages of Change for Physical Activity, and Health Outcomes in a Cross-Cultural Sample.

BACKGROUND: A successful transition from late adolescence to adulthood is essential. Physical activity (PA) can support this process and lead to positive health outcomes. The change in PA from inactive to active stages is influenced by psychosocial correlates, and as such, this study tested the relationships among psychosocial correlates, stages of change for PA and health outcomes in university students from Hong Kong (n = 404) and Germany (n = 366). METHODS: The questionnaire contained (1) PA and stages of change; (2) 10 psychosocial correlates including outcome expectations, affective attitude, barriers, self-efficacy, body-concept, plans, intrinsic motivation, activity emotions, assessment of activity situation, and social support; and (3) 5 health outcomes, including fitness, subjective well-being, health satisfaction, physical complaints, and BMI. RESULTS: Barriers and intrinsic motivation were the critical psychosocial variables related to stages of change. Specific planning was more important for Hong Kong students' stage progression within inactive stages. Competitive or enjoyable PA programs were more effective for male students moving from inactive to active stages. The link between stages of change for PA and health outcomes (ie, fitness, health satisfaction) was well established. CONCLUSION: Public health researchers should conduct effective psychosocial interventions that motivate young adults to engage in PA for positive health outcomes.
