Development and Validation of the Football Emotion Scale for Chinese Youth Players: A Psychometric Study

Emotions play a pivotal role in the performance and development of young athletes, yet a significant gap has existed in the availability of a validated instrument to specifically measure football-related emotions among this demographic. Addressing this critical need, a recent study has successfully developed and validated the Football Emotion Scale (FES) tailored for Chinese youth football players. This groundbreaking research, published in Frontiers in Psychology, provides a robust and reliable tool that promises to deepen our understanding of the emotional landscape experienced by young footballers and inform crucial interventions aimed at enhancing their development and overall well-being.

The FES was meticulously crafted and validated through a rigorous two-phase process involving a substantial number of participants across Shandong Province, China. The study’s findings underscore the multifaceted nature of emotions in youth football, revealing a six-factor structure that encompasses positive and negative emotional experiences across match play, training sessions, and broader cultural engagement with the sport. This comprehensive approach acknowledges that a young player’s emotional state is influenced not only by the immediate pressures of competition but also by the daily grind of practice and their evolving relationship with football as a significant aspect of their lives.

Background: The Crucial Role of Emotions in Youth Sports

The significance of emotional experiences in sports, particularly for young athletes, has been a growing area of focus in sports psychology. Research has consistently highlighted that emotions are not merely byproducts of athletic activity but active determinants of performance, learning, and psychological health. Theoretical models such as the Individual Affect-related Performance Zones (IAPZ) and the Individual Zone of Optimal Functioning (IZOF) have long suggested that athletes possess unique emotional ranges conducive to optimal performance. More contemporary understanding views emotions as a complex interplay of subjective feelings, physiological responses, cognitive appraisals, and behavioral expressions.

In the context of football, a sport characterized by intense competition, rapid decision-making, and intricate team dynamics, emotions are particularly salient. Studies have indicated that positive emotions like excitement and confidence can bolster performance, while negative emotions such as anxiety and frustration can hinder it. For young players navigating the dual challenges of athletic development and adolescent psychological growth, the impact of these emotional states can be profound, influencing their motivation, resilience, and long-term engagement with the sport. However, the specific nuances of emotional experiences in youth football, especially within diverse cultural contexts like China, have remained largely under-researched due to a lack of appropriate measurement tools.

Developing the Football Emotion Scale (FES)

The journey to create the FES began with an extensive review of existing literature on sports emotions, drawing upon established instruments like the Sport Emotion Questionnaire (SEQ) and the Positive and Negative Affect Schedule (PANAS). This foundational research was augmented by in-depth consultations with six experts, including seasoned youth football coaches, sports psychology researchers specializing in adolescent development, and a former professional player. These consultations provided invaluable insights into the specific emotional challenges and experiences unique to young Chinese footballers, considering their developmental stage and cultural background.

Following this comprehensive exploration, an initial pool of 42 items was developed, designed to capture a broad spectrum of emotions across six theoretical dimensions: positive and negative emotions related to matches, training, and football culture. The content validity of these items was rigorously assessed by nine experts, leading to the refinement and replacement of certain items to ensure optimal relevance and clarity within the Chinese youth football context. A subsequent pre-testing phase with 30 young players confirmed the questionnaire’s comprehensibility and practicality, with minimal revisions required. The final version of the FES retained a structure of six subscales, each rated on a 5-point Likert scale.

Methodology and Psychometric Validation

The study employed a robust cross-sectional survey design across two phases. The initial phase involved exploratory factor analysis (EFA) with 492 youth football players, while the second phase utilized confirmatory factor analysis (CFA) with a separate sample of 450 players. Participants were drawn from National Youth Campus Football Featured Schools across 12 cities in Shandong Province, a region known for its significant investment in football development. This multi-stage sampling approach, while ensuring access to relevant participants, provides a detailed snapshot of emotions within this specific developmental and regional context.

To ensure the highest ethical standards, the study obtained ethical approval from the Human Research Ethics Committee of Universiti Sains Malaysia. Data collection was conducted face-to-face to maximize response rates and data quality, with research assistants present to offer clarification.

The statistical analysis was comprehensive, employing IBM SPSS Statistics and Mplus software. Preliminary analyses included checks for multicollinearity and normality. EFA, utilizing Principal Axis Factoring with Promax rotation, was employed to identify the underlying factor structure. The Kaiser-Meyer-Olkin measure (0.906) and Bartlett’s test of sphericity (p < 0.001) confirmed the suitability of the data for factor analysis. This process led to the identification of a six-factor structure explaining 67.027% of the total variance, with 26 items ultimately retained after iterative refinement.

Confirmatory factor analysis was then used to test the identified structure. Two models were evaluated: a first-order model with six correlated factors and a second-order model with two higher-order factors (Football Positive Emotion and Football Negative Emotion). The robust maximum likelihood estimator (MLR) was used for CFA due to deviations from normality in the data, providing reliable estimates and adjusted statistics. Model fit was assessed using standard indices such as RMSEA, CFI, TLI, and SRMR, with excellent fit indices observed for both models (RMSEA = 0.033, CFI = 0.971, TLI = 0.968, SRMR = 0.037).

Key Findings: A Robust and Reliable Instrument

The results of the psychometric validation are highly encouraging, demonstrating that the FES is a sound instrument for measuring football-specific emotions in Chinese youth players.

• Factor Structure: EFA identified a six-factor structure comprising: Football Positive Match Emotions, Football Negative Match Emotions, Football Positive Training Emotions, Football Negative Training Emotions, Football Positive Culture Emotions, and Football Negative Culture Emotions. CFA confirmed this structure and further supported a second-order model where these six factors loaded onto two broader dimensions: Football Positive Emotion and Football Negative Emotion. This hierarchical structure provides a nuanced yet parsimonious way to understand the emotional experiences of young players.

• Internal Consistency: The scale exhibited strong internal consistency across all factors, with Cronbach’s alpha coefficients ranging from 0.793 to 0.894. This indicates that the items within each factor reliably measure the same underlying construct.

• Test-Retest Reliability: A subset of 50 participants completed the FES on two occasions separated by 14 days. The Intraclass Correlation Coefficients (ICC) demonstrated good to excellent temporal stability, ranging from 0.703 to 0.915. This suggests that the FES yields consistent results over time, making it suitable for longitudinal research and monitoring emotional changes.

• Construct Validity: The FES demonstrated satisfactory construct validity. Composite Reliability (CR) values ranged from 0.793 to 0.894, and Average Variance Extracted (AVE) values ranged from 0.505 to 0.641, indicating good internal convergence within factors. Discriminant validity was supported by the Fornell-Larcker criterion, ensuring that each factor is distinct from others.

Implications and Future Directions

The development and validation of the FES represent a significant advancement for sports psychology research and practice in China and potentially beyond. The scale’s ability to capture emotions across match play, training, and cultural engagement provides a more holistic understanding of the youth football experience. Coaches, sports psychologists, and educators can now utilize this tool to:

• Identify Emotional Patterns: Understand the prevalent emotional states of young players during different football activities.
• Inform Interventions: Design targeted psychological interventions to help players manage negative emotions like anxiety and frustration, and enhance positive emotions like enjoyment and confidence.
• Monitor Player Development: Track emotional changes over time and assess the impact of training programs or competitive experiences on player well-being.
• Advance Research: Provide a standardized measure for future research on the relationship between emotions, performance, and mental health in youth football.

Despite the robust validation, the researchers acknowledge certain limitations. The study’s focus on Shandong Province means that generalizability to other regions, age groups, or competitive levels requires further investigation. Future research could expand validation efforts to diverse geographical and cultural settings. Longitudinal studies are also recommended to assess the FES’s sensitivity to change and its predictive validity for performance and well-being outcomes. Furthermore, exploring convergent validity by correlating FES scores with other established emotion measures or behavioral indicators would further strengthen the evidence base.

Conclusion

The Football Emotion Scale (FES) has emerged as a psychometrically sound and reliable instrument for assessing the football-specific emotional experiences of Chinese youth players. Its comprehensive structure, encompassing match, training, and cultural dimensions, along with its strong reliability and validity, make it an invaluable tool for researchers and practitioners alike. By providing a deeper insight into the emotional lives of young footballers, the FES is poised to play a crucial role in fostering a more supportive and effective environment for their development, both on and off the pitch. This study marks a significant step forward in understanding and addressing the complex emotional landscape that shapes the journey of young athletes in the world’s most popular sport.
