Relationship Between Athletes' History of Stressors and Sport Injury: A Systematic Review and Meta-Analysis.

A history of stressors in athletes represents psychosocial factors that may lead to sport injury. However, empirical studies have provided varying results for the relationship between stress history and sport injury. We examined prior literature on the stress history - sport injury relationship within a systematic review and, by meta-analysis, we offered a pooled estimate of the strength of this relationship. We searched seven major academic databases (Sportdiscus, Psyinfo, Academic Search Premier, Ovid, Scopus, Web of Science, and PubMed) from January 2000 to September 2023 and identified 19 empirical studies that examined injuries in sports contexts for meta-analysis. In 19 empirical studies of moderate to high publication quality, we found moderate heterogeneity (Q(17) = 98.61; p < .001), low sensitivity (I2 77.82-83.77), and low publication bias (Z-value = 7.74; p < .001). Further, using a random effect estimate-r, we found a low but significant correlation between stress history and sport injury, yielding a small overall effect size (ES) of r = .12. Furthermore, moderation analyses found adolescents (r = .14), contact-sport athletes (r = .09), non-elite athletes (r = .13), and non-European athletes (America r = .16; Asia r = .14; Oceania r = .14) to have a relatively higher ES than their counterparts in this stress history/sport injury relationship. We concluded that inevitable life stressors may lead to many negative consequences for athletes, such that sports professionals should provide stress management educational programs to enhance athletes' health and well-being.

Interactive effects of dispositional mindfulness and PETTLEP imagery training on basketball shooting performance: A randomized controlled trial.

The purpose of this study was to examine the interactive effects of dispositional mindfulness and visualized PETTLEP imagery training on basketball mid-range shooting performance and retention. Seventy-three participants (M age = 20.32 ± 1.09) with high/low dispositional mindfulness (high n = 35; low n = 38) selected out of 302 college students were randomly assigned into the following six groups: (a) high mindfulness internal imagery (H-II, n = 13); (b) high mindfulness external imagery (H-EI, n = 11); (c) high mindfulness control (H-CO, n = 11); (d) low mindfulness internal imagery (L-II, n = 13); (e) low mindfulness external imagery (L-EI, n = 12); and (f) low mindfulness control (L-CO, n = 13). Participants engaged in a pretest to measure their basketball shooting performance, then participated in a 6-week (3 times/per-week) intervention, plus a posttest and retention test. A three-way 2 (high/low mindfulness) X 3 (treatments: internal-, external imagery, and control) X 3 (measurement time: pretest, posttest, and retention) mixed ANOVA statistical analysis found dispositional mindfulness interacted with treatments and measurement time. The main effects showed high dispositional mindfulness performed better than low dispositional mindfulness, and internal imagery training performed better than external imagery training on mid-range basketball performance at retention. The 3-way interaction indicated that when using either internal or external imagery, high dispositional mindfulness performed better than low mindfulness on retention but not posttest. For 2-way interaction, high dispositional mindfulness performed better than low dispositional mindfulness on retention but not posttest. Our results extended current knowledge on sport imagery and dispositional mindfulness and gained several theoretical implications for researchers. The limitations, future research directions, and practical implications were also discussed.

Influence of mental energy on volleyball competition performance: a field test.

Athletic mental energy is a newly emerging research topic in sport science. However, whether it can predict objective performance in competition remains unexplored. Thus, the purpose of this study was to examine the predictability of mental energy on volleyball competition performance. We recruited 81 male volleyball players (Mage = 21.11 years ± SD = 1.81) who participated in the last 16 remaining teams in a college volleyball tournament. We assessed participants' mental energy the night before the competition and collected their competition performance over the next 3 days. We used six indices of the Volleyball Information System (VIS) developed by the International Volleyball Federation (FIVB) to examine its associations with mental energy. All six factors of mental energy -motivation, tirelessness, calm, vigor, confidence, and concentration correlated with volleyball competition performance. Further, a hierarchical regression found mental energy predicted volleyball receivers' performance (R2 = .23). The findings advance our knowledge of mental energy and objective performance in competition. We suggest that future studies may examine the effects of mental energy on different sports with different performance indices.

Factorial validity and measurement invariance of the psychological need satisfaction in exercise scale across gender.

BACKGROUND: Based on the self-determination theory, the psychological requirements for competence, autonomy, and relatedness boost beneficial exercise behaviour for healthy living. However, there is no valid, reliable Malay version scale to investigate the extent to which these psychological needs are met. The main purpose of this study was to examine the psychometric properties of a Malay version of the Psychological Need Satisfaction in Exercise (PNSE-M) scale. In addition, the purpose of this study was to confirm the measurement and structural invariance of the PNSE-M across gender. METHODS: The study participants included 919 students (male: 49.6%, female: 50.4%), with a mean age of 20.4 years (standard deviation = 1.5). The participants were selected through convenience sampling. The 18-item PNSE-M was used to measure psychological need satisfaction in exercise. The English version of the PNSE was translated into Malay using standard forward-backward translation. Confirmatory factor analysis (CFA) and invariance tests were performed on the three domains of the PNSE-M model. Composite reliability (CR), average variance extracted (AVE), internal consistency based on Cronbach's alpha, and test-retest reliabilities using intraclass correlation coefficient (ICC) were also computed. RESULTS: After some model re-specification, the CFA findings based on the hypothesised measurement model of three factors and 18 items indicated acceptable factor structure (CFI = .936, TLI = .923, SRMR = .054, RMSEA = .059). The CR and AVE values were .864-.902 and .573-.617, respectively. Cronbach's alpha was .891-.908, and the ICC was .980-.985. The findings supported the full measurement and structural invariance of the PNSE-M for both male and female participants. The CFA model matched the data well for both male (CFI = .926, SRMR = .057, RMSEA = .066) and female (CFI = .926, SRMR = .060, RMSEA = .065) participants. CONCLUSION: The PNSE-M with three factors and 18 items is considered to be a valid, reliable instrument for university students in Malaysia. It is valid for use to make meaningful comparisons across gender.

Combinations of action observation and motor imagery on golf putting's performance.

Motor imagery (MI) and action observation (AO) have been found to enhance motor performance, but recent research found that a combination of action observation and motor imagery (AOMI) together is even better. Despite this initial finding, the most effective way to combine them is unknown. The present study examined the effects of synchronized (i e., concurrently doing AO and MI), asynchronised (i.e., first doing AO then MI), and progressive (first asynchronised approach, then doing synchronized approach) AOMI on golf putting performance and learning. We recruited 45 university students (Mage = 20.18 + 1.32 years; males = 23, females = 22) and randomly assigned them into the following four groups: synchronized group (S-AOMI), asynchronised group (A-AOMI), progressive group (A-S-AOMI), and a control group with a pre-post research design. Participants engaged in a 6-week (three times/per-week) intervention, plus two retention tests. A two-way (group × time) mixed ANOVA statistical analysis found that the three experimental groups performed better than the control group after intervention. However, we found progressive and asynchronised had better golf putting scores than synchronized group and the control group on the retention tests. Our results advance knowledge in AOMI research, but it needs more research to reveal the best way of combining AOMI in the future. Theoretical implications, limitations, applications, and future suggestions are also discussed.

Pre-competition mental energy and performance relationships among physically disabled table tennis players.

Energy is essential to human daily functioning and performance. However, the association of mental energy with athletes' performance has rarely been examined. We attempted to examine the pre-competition mental energy-performance relationships by two studies. Study 1 administered Athletic Mental Energy Scale (AMES, Lu et al., 2018) to nine elite physically-disabled table tennis players one day before competition in 5 international tournaments. Then, we collected their subjective performance after each competition. In Study 2, we sampled 77 National-level physically-disabled table tennis players and examined the pre-competition mental energy-performance relationship as the procedure in Study 1. Results from Study 1 provided initial findings of how pre-competition mental energy is associated with performance and portrayed in elite physically-disabled table tennis players. Results from Study 2 further confirmed the pre-competition mental energy- performance relationships. We suggested future studies to examine the mental energy-performance relationships in physically-disabled and abled athletes and different sports.

Interactive Effects on Motor Performance of Mindfulness, Performance Under Pressure, Self-Talk, and Motor Task Characteristics.

High mindfulness individuals have been found to perform better on motor tasks under various conditions, but it is unknown whether mindfulness and performance relate when performing under pressure or using different types of self-talk with different motor tasks. In this study, 46 male participants (Mage = 21.4, SD = 1.72 years) with high mindfulness (n = 23) and low mindfulness (n = 23) performed dart-throwing and two-hand coordination tasks under pressure and non-pressure conditions and when using instructional and unrelated self-talk. First, on the two-hand coordination task, a three-way mixed ANOVA found: (a) a significant 3-way interaction in which a significantly poorer performance occurred under pressure (vs. without pressure), with low (vs. high) mindfulness and when using unrelated (vs. instructional) self-talk and (b) a significant interaction in which, both under pressure and not, both high and low mindfulness participants performed comparably when using instructional (vs. unrelated) self-talk. Second, on the dart-throwing task, mindfulness interacted with self-talk such that both high and low mindfulness participants performed better when using instructional self-talk, and pressure interacted with self-talk such that participants using instructional (vs. unrelated) self-talk performed better in both pressure and non-pressure conditions. We concluded that instructional self-talk was a useful cognitive strategy, perhaps particularly in pressure conditions and regardless of the degree of mindfulness, and its effectiveness extended to two different motor tasks. We discussed the theoretical implications of these findings, in terms of attention theory, self-talk, and motor control; and we highlighted our study's limitations and practical applications and gave recommendations for future research.

A Systematic Review and Meta-Analysis of the Effects of Outdoor Education Programs on Adolescents' Self-Efficacy.

While prior research has generally found Outdoor Education Programs (OEPs) to be beneficial to adolescents' self-efficacy, we sought to conduct a meta-analytic review of prior studies in this area in order to pinpoint the key elements to OEPs' effectiveness. Following Cooper's guidelines for synthesis research and meta-analysis, we searched six electronic databases for relevant articles: PubMed, Sciencedirect, Medline, PsycArticles, and Behavioral Sciences Collection of EBSCO, and Eric. Selection criteria were: Populations, Interventions, Comparators, Outcomes, Study Design (PICOS), and Methodological Index for Non-randomized Studies (MINORS). We estimated the effect size of the selected studies with a 95% confidence interval (CI), estimated I-squared (I2) for heterogeneity analysis and analyzed publication bias by Egger's test. After excluding many studies, we reviewed 12 studies with 2,642 participants that were deemed to be eligible for final analysis. We discovered a high level of heterogeneity (I-squared value =82.474) in the findings of the selected studies. Our meta-analyses revealed that adolescents participating in OEPs enhanced their self-efficacy (medium effect size; Hedges's g = 0.597) but this enhancement was moderated by participants' mental health status, the length of the experiments, study groups, and the duration of the intervention. We found no evidence of publication bias (Egger: bias = 2.001, 95% CI = -0.736 to 4.739, p = .137). We discussed our research limitations and the theoretical and practical implications of these findings and made recommendations for future research.

Interaction of mindfulness disposition and instructional self-talk on motor performance: a laboratory exploration.

In considering that high mindfulness disposition individuals possess a unique ability to maintain attention and awareness, and attention is one of the key mechanisms of instructional self-talk, the purpose of this study was to examine the interaction of mindfulness disposition and instructional self-talk on motor performance. Forty-nine college students (M age = 18.96 ± 1.08) with high/low mindfulness disposition (high n = 23; low n = 26) selected out of 126 college students performed a discrete motor task (standing long jump) and a continuous motor task (line tracking task) under instructional and unrelated self-talk conditions. Two separate 2 (self-talk type) X 2 (high/low mindfulness) mixed design ANOVA statistical analyses indicated that mindfulness disposition interacted with unrelated self-talk in the line tracking task. Specifically, low mindfulness participants performed poorer than high mindfulness participants in line tracking task under unrelated self-talk. Further, participants performed better in both standing long jump and line tracking under instructional self-talk than unrelated self-talk. Results not only revealed the triangular relationships among mindfulness, self-talk, and motor performance but also indirectly support the role of attention in self-talk effectiveness. Limitations, future research directions, and practical implications were discussed.

Measuring Athletic Mental Energy (AME): Instrument Development and Validation.

Although considerable research indicates that mental energy is an important factor in many domains, including athletic performance (Cook and Davis, 2006), athletic mental energy (AME) has never been conceptualized and measured. Therefore, the aim of this study was to conceptualize and develop a reliable and valid instrument to assess AME. In Study 1, a focus group interview established the initial framework of AME. Study 2 used a survey to collect athletes' experiences of AME and develop a scale draft titled "Athletic Mental Energy Scale (AMES)." In Study 3, we examined the psychometric properties and the underlying structure of AMES via item analysis, internal consistency, and exploratory factor analysis (EFA). In Study 4, we used confirmatory factor analysis (CFA) to examine AMES's factorial validity; and examined concurrent and discriminant validity by examining correlations with athletes' life stress, positive state of mind, and burnout. In study 5, we examined the measurement invariance of the 6-factor, 18-item AMES with Taiwanese and Malaysian samples. Study 6 examined the predictive validity by comparing AMES scores of successful and unsuccessful martial artists. Across these phases, results showed a 6-factor, 18-item AMES had adequate content validity, factorial structure, nomological validity, discriminant validity, predictive validity, measurement invariance, and reliability. We suggest future studies may use AMES to examine its relationships with athletes' cognition, affect, and performance. The application of AMES in sport psychology was also discussed.

Examining the stress-burnout relationship: the mediating role of negative thoughts.

BACKGROUND: Using Smith's (1986) cognitive-affective model of athletic burnout as a guiding framework, the purpose of this study was to examine the relationships among athletes' stress in life, negative thoughts, and the mediating role of negative thoughts on the stress-burnout relationship. METHODS: A total of 300 college student-athletes (males = 174; females = 126, Mage  = 20.43 y, SD = 1.68) completed the College Student Athlete's Life Stress Scale (CSALSS; Lu et al., 2012), the Automatic Thoughts Questionnaire (ATQ; Hollon & Kendall, 1980), and the Athlete Burnout Questionnaire (ABQ; Raedeke & Smith, 2001). RESULTS: Correlational analyses found that two types of life stress and four types of negative thoughts correlated with burnout. Additionally, hierarchical regression analyses found that four types of negative thoughts partially mediated the stress-burnout relationship. DISCUSSION: We concluded that an athlete's negative thoughts play a pivotal role in predicting athletes' stress-burnout relationship. Future study may examine how irrational cognition influences athletes' motivation and psychological well-being.

Adolescents' physical activities and peer norms: the mediating role of self-efficacy.

The purpose of the present study was to examine the relations among adolescents' self-efficacy and social norms, and physical activity and whether self-efficacy mediated the relationship between social norms and physical activity. 400 junior high school students (202 boys, 198 girls, 2 not identified; M age = 15.3yr., SD = 0.6) completed a demographic questionnaire, the International Physical Activity Questionnaire (IPAQ), the Perceived Self-Efficacy in Physical Activity Scale, and the Physical Activity Social Norms Scale. Regression analyses indicated that both self-efficacy and social norms predicted physical activity. Self-efficacy fully mediated the relationship between peer norms and physical activity for boys but partially mediated the relationship for girls. An application of the results may be to foster self-efficacy and peer norms as a motivational strategy for supporting increased physical activity.

Pathways from fear of falling to quality of life: the mediating effect of the self-concept of health and physical independence.

OBJECTIVES: Fear of falling leads to many adverse consequences and may compromise the quality of life of older adults. Psychological factors are potential mediators between the fear of falling and quality of life, but have yet to be explored in detail. This study presents results from examining the mediating effect of the self-concept of health and physical independence. Data from Western and Eastern countries were compared. METHOD: Concerns about falling, the level of participation in physical activities, the self-concept of health and physical independence, and health-related quality of life were measured using samples from Taiwan (n = 193) and Germany (n = 182). Multiple regression models were used to test the mediating effects. RESULTS: The relationship between fear of falling and quality of life was partially mediated through participation in physical activities and the self-concept of health and physical independence in both the Taiwanese and German samples. In particular, the self-concept of health and physical independence of the Taiwanese sample resulted in the strongest mediating effect. CONCLUSION: Potential mediating mechanisms through both participation in physical activities and the self-concept of health and physical independence provide useful information for understanding related theories and for explicating interventions. Cultural factors should also be accounted for when conducting research and programs related to the fear of falling.

Injured athletes' rehabilitation beliefs and subjective well-being: the contribution of hope and social support.

CONTEXT: Injuries are a significant problem in the world of sports. Hope and social support are very important features in providing psychological help as people face life challenges such as sport injuries. OBJECTIVE: To examine how hope and social support uniquely and jointly predict postinjury rehabilitation beliefs, rehabilitation behavior, and subjective well-being. DESIGN: Cross-sectional study. SETTING: Four sports-injury rehabilitation centers of local universities in Taiwan. PARTICIPANTS: A total of 224 injured Taiwanese collegiate student-athletes. MAIN OUTCOMES MEASURE(S): The Trait Hope Scale, the Sports Injury Rehabilitation Beliefs Survey, the Satisfaction with Life Scale, the Positive Affective and Negative Affective Scale, and the Multidimensional Scale of Perceived Social Support were completed by participants after they received their regular rehabilitation treatment. RESULTS: We conducted hierarchical regressions and found that social support and 2 types of hope in injured athletes predicted their rehabilitation beliefs and subjective well-being. However, only hope agency predicted their rehabilitation behavior. Also, hope and social support had an interactive effect on the prediction of subjective well-being; for participants with low hope pathways, the perception of more social support was associated with higher levels of subjective well-being, whereas social support had only a relatively low association with subjective well-being among participants with high hope pathways. CONCLUSIONS: Enhancing hope perceptions and strengthening injured athletes' social support during rehabilitation are beneficial to rehabilitation behavior and subjective well-being.

Relationship between athletes' emotional intelligence and precompetitive anxiety.

This study examined the relationship between athletes' Emotional Intelligence (EI) and precompetitive anxiety. Taiwanese intercollegiate track and field athletes (N = 111; 64 men, 47 women) completed the Bar-On EQ-i 1 mo. before a1 national intercollegiate athletic meet, and the Competition State Anxiety Inventory-2R 1 hr. before the competition. Analyses indicated that participants with the lowest EI scores reported greater intensity of precompetitive cognitive anxiety than those with the highest EI scores. No other statistically significant differences were found among the groups. Further, correlational analyses and multiple stepwise regression analyses revealed that EI components such as stress management, intrapersonal EI, and interpersonal EI were associated with precompetitive anxiety. Current EI measures provide limited understanding of precompetitive anxiety. A sport-specific EI measure is needed for future research.
