2.1. Effects of Social Support on the Subjective Well-being of College Athletes
Social support is defined as the assistance and resources provided by an individual’s social network [10, 20], with sources and content that vary across different contexts. Within the realm of sports research, coaches and teammates are recognized as crucial supporters of athletes. Furthermore, for college students transitioning to adulthood, family support remains instrumental in their development. Consequently, this study conceptualizes social support for collegiate athletes as deriving from family, coaches, and teammates.
Social support is widely considered a crucial resource for mental well-being among athletes [13, 21]. Its positive effects can be explained by the main and buffering effect models of social support proposed by Cohen and Wills [22]. The main effect model suggests that social support directly contributes to well-being since it enhances an individual’s predictability and positive affect [22]. The buffering model posits that social support expands an individual's resource pool when stress arises, which aids in coping with stressful events [22, 23]. In the context of college sports, the model indicates that support from family, teammates, and coaches positively impacts athletes’ well-being, regardless of whether they experience stressful events.
Several studies on youth athletes have demonstrated the positive effects of social support on subjective well-being outcomes. Research in non-stressful and chronic stress contexts consistently shows a positive correlation between social support and mental health outcomes in college athletes, including positive emotions and life satisfaction [11, 24]. Additionally, researchers have focused on the buffering role of social support in stressful situations, finding that it can reduce stress during training interruptions (e.g., during pandemics) and competitions, thereby enhancing the subjective well-being of young athletes [13, 25–26]. These studies suggested that social support mitigates mental health risks across various stressor severities and types. For instance, Mitchell et al. found that social support significantly alleviated negative psychological responses, irrespective of the type of injury, highlighting its universal benefits [27]. Additionally, Sullivan et al. reported that, after controlling for injury severity, high-quality social support significantly reduced depression and anxiety symptoms in injured athletes, improving their post-injury mental health [13].
Although many studies have examined the link between social support and psychological well-being in young athletes, they primarily focus on developed countries, leaving a significant gap concerning developing regions. Compared to developed countries, developing regions lack formal support from sports associations and organizations for the well-being and health of young athletes [28, 29]. This indicates that in developing countries, social support is crucial for promoting the psychological well-being of young athletes. Therefore, this study aims to bridge this gap by investigating Chinese college athletes to provide empirical evidence within a developing country context. Based on prior research on social support and young athletes' mental health, we propose the following research hypotheses:
H1: Social support is positively associated with subjective well-being among Chinese college athletes.
2.2. P-E Fit as a Mediator between Social Support and Subjective Well-being
P-E fit encapsulates an individual's compatibility with their organizational environment [30, 31], suggesting a harmonious alignment between the individual's and the organization's characteristics [32]. P-E fit theory is predominantly explored in workplace studies to examine the impact of the work environment on employee well-being [33]. Given the employer-employee dynamics of the university-athlete relationship [34], P-E fit theory has increasingly been applied to studies concerning the well-being of young athletes [35, 36]. In this study, P-E fit is defined as the alignment between the characteristics of college athletes and their respective sports teams, encompassing person-organization fit, person-group fit, person-job fit, and person-supervisor fit [32]. Specifically, person-organization (P-O) fit represents the congruence between the training team's values and those of the athlete; person-job (P-J) fit assesses the alignment of the athlete's skills and abilities with the team's needs; person-group (P-G) fit reflects the harmony among team members; and person-supervisor (P-S) fit examines the compatibility between the coach's and athlete's personalities, values, and goals.
P-E fit theory suggests that individuals have a natural tendency to blend in with their environment or contextual affiliations [37, 38], and a supportive environment can enhance this tendency [39]. The support college athletes receive is closely linked to their P-E fit with sports teams. Social support provides essential emotional and professional resources that facilitate integration into groups and adaptation to team roles. With adequate social support, college athletes are more likely to adapt to their training environment and integrate well with their team. However, the impact of social support on athletes' P-E fit remains underexplored, with only a few studies addressing its aspects [40, 41]. For example, Worley et al. found that servant leadership in team leaders boosts athletes’ team cohesion and social identification [41]. Unlike traditional leaders focused on organizational goals, servant leaders prioritize addressing team members’ needs and offering support [42]. Team cohesion signifies harmonious interpersonal relationships, while team member identification denotes loyalty to the team. These elements correspond to the person-group fit and person-organization fit aspects of P-E fit, respectively. This evidence underscores the positive relationship between social support and athletes' perceived P-E fit.
Enhancing subjective well-being is recognized as a positive outcome of high levels of P-E fit, as evidenced by previous studies in youth sports. For example, a study on young soccer players found that perceived alignment with their team, including similarity with teammates, correlates with improved subjective well-being [43]. Beattie and Turner found that P-E fit positively correlates with academic satisfaction among collegiate athletes, highlighting the statistical significance of the fit between individuals and their teammates, which is the core content of person-group (P-G) fit [44]. In another study, they explored how P-E fit affects collegiate athletes' satisfaction, emphasizing the critical role of person-supervisor (P-S) fit [45]. Given the importance of sports and academic satisfaction to the subjective well-being of college athletes, these findings collectively affirm the positive relationship between P-E fit and subjective well-being in this population.
In summary, P-E fit may mediate the relationship between social support and the subjective well-being of college athletes. However, empirical studies supporting this framework primarily examine variables similar to social support and P-E fit. More direct research is needed to confirm P-E fit's mediating role in this relationship. Consequently, we propose the second hypothesis of this study:
H2: P-E fit positively mediates the relationship between social support and the subjective well-being of college athletes.
2.3. Basic Psychological Needs as a Mediator between Social Support and Subjective Well-being
Basic Psychological Needs Theory is a widely used motivational framework for examining relationship quality and athlete well-being in sports contexts [17–18, 46]. This theory suggests that human beings inherently pursue three fundamental psychological needs: relatedness, competence, and autonomy. The need for relatedness stems from the desire to feel valued and accepted. The need for competence arises from the desire to engage effectively and succeed in one's environment, reflecting a quest for self-assurance in personal abilities. Finally, autonomy involves the need for meaningful choices and active participation in decision-making, reflecting the ability to align actions with personal values and take responsibility for them. BPNT also posits that social-contextual factors influence the extent to which psychological needs are satisfied, and a supportive social environment enhances the fulfillment of these needs [17, 47].
Social support can be viewed as a social-contextual factor that promotes the satisfaction of three basic needs among college athletes. The substantial social support observed in athletes likely reflects robust sports social networks, such as strong teammate relationships. This enhances their sense of social belonging within the sports group, thereby fostering the satisfaction of relatedness needs [48]. Effective social support, exemplified by autonomy support, involves teammates expressing confidence in an athlete's capabilities, parents demonstrating understanding, and coaches offering information and choices. Such support promotes self-initiative and self-esteem, thus satisfying the need for autonomy [49]. Effective social support, often exemplified by autonomy support, may manifest as teammates' confidence in an athlete's abilities, parents demonstrating understanding, and coaches offering information and choices [18, 46]. Such support enhances self-initiative and self-esteem, thereby fulfilling the need for autonomy [49]. Furthermore, as social support enhances athletes' abilities, it boosts their sense of control over their sporting environment, thereby satisfying their need for competence [49].
In the context of youth sports, prior studies have demonstrated that coaches and teammates play a pivotal role in fulfilling collegiate athletes' three basic psychological needs [46, 50]. For example, Fransen et al. found that competency support from team leaders increased levels of competency satisfaction in athletes [51]. In this study, researchers examined social support from coaches and teammates for high school student-athletes, finding that the greatest amount of variability in autonomy and relatedness was predicted by coach support and peer support, respectively [52]. The existing literature on youth sports predominantly highlights the importance of support from coaches and teammates, with comparatively less emphasis on parental support. This oversight likely arises from the presumption that families primarily support athletes during their adolescent years [50]. However, as emerging adults transition from adolescence, college athletes predominantly depend on parental support for economic and emotional needs, which is likely crucial for satisfying their basic psychological needs [53]. Despite limited research, a positive correlation has been found between parental support and the satisfaction of athletes’ psychological needs [54, 55].
Numerous studies have examined the mediating role of needs satisfaction between social support and the well-being of athletes. For example, Jowett et al. analyzed cross-sectional data from five countries, showing that athletes who perceived higher levels of coach support experienced greater satisfaction of basic needs, which was associated with enhanced well-being [56]. Similarly, Balaguer et al. found in a longitudinal study that football players' perception of coaching autonomy support at the beginning of the season could predict their subjective well-being at the end of the season through need satisfaction [57]. To summarize, both cross-sectional and longitudinal research suggested that the fulfillment of athletes' psychological needs is closely linked to external support, which positively correlates with their subjective well-being. Consequently, we propose the following third research hypothesis for this study:
H3: Basic psychological need satisfaction positively mediates the relationship between social support and the subjective well-being of college athletes.
2.4. Chain Mediation of P-E Fit and Basic Psychological Needs
Recently, researchers have shown interest in the link between P-E fit and BPNT, suggesting that satisfaction of basic psychological needs may mediate the relationship between P-E fit and subjective well-being [58–60]. According to BPNT, individuals seek environments that fulfill their psychological needs for autonomy, relatedness, and competence. P-E fit may be a precursor influencing the satisfaction of basic needs. Some researchers have proposed developing an extended model of basic psychological needs that integrates the P-E fit framework, providing a theoretical rationale for this integration [60].
Firstly, alignment with the surrounding environment facilitates the self-validation of individual beliefs, attitudes, and preferences. When an individual's goals and values align with the organization, they are more likely to feel their actions are voluntary and self-chosen, thereby enhancing the satisfaction of autonomy, even when their work activities are guided by organizational policies and procedures [61]. Secondly, the match between an individual's surrounding environment and their characteristics can diminish feelings of uncertainty while augmenting a sense of security and belonging [62]. Alignment with others in specific contexts can fulfill an individual’s need for interpersonal attachment [62], thus satisfying their need for relevance [38]. Finally, P-E fit can potentially enhance the satisfaction of competence needs. For example, in workplace settings, high person-job fit suggests an individual can meet the organization’s demands, thereby fostering a sense of competence. Additionally, alignment of an individual's values and goals with their colleagues' may further augment satisfaction with competence needs during the pursuit of shared objective [60].
Research on the relationship between P-E fit and basic needs satisfaction is limited and mainly focuses on workplace settings [59, 63]. For example, Greguras and Diefendorff demonstrated that P-E fit positively influences the fulfillment of basic psychological needs. Additional evidence comes from studies on related P-E fit conceptualizations [59]. For instance, Wang et al. found that higher consistency in P-E fit correlates with increased psychological security [64]. Psychological security, similar to the concepts of competence and autonomy, refers to the feeling of being safe to express one's true self in the workplace, supported by managerial and collegial trust and friendliness. Other research has examined the relationship between P-E adaptation dimensions and the satisfaction of basic needs [65, 66]. For example, Sharom found that person-organization (P-O) fit enhances employees' satisfaction of basic psychological needs [66]. Given the validated positive correlation between P-E fit and psychological need satisfaction in various work environments, it is reasonable to assume that this relationship extends to college sports teams, as they share workplace attributes.
In summary, existing research indicates that P-E fit enhances individuals' perceptions of social support from their surrounding environment, thereby satisfying their basic psychological needs. These insights could potentially extend to sports research, particularly considering that collegiate athletes share commonalities, such as the obligation to fulfill organizational tasks. Therefore, we propose the following research hypothesis:
H4: P-E fit and basic psychological needs may function as sequential mediators between social support and subjective well-being among college students.
2.5. The Present Study
Previous research has extensively investigated the effects of social support on the mental well-being of college athletes. However, significant gaps remain in this research domain, particularly regarding the mediating mechanisms through which social support influences college athletes' subjective well-being.
Firstly, the P-E fit theory elucidates the congruence between individuals and their environments, highlighting its impact on various well-being outcomes. While P-E fit is commonly applied in sports research to investigate athlete development, its application in studying athletes' mental well-being is less common.
Secondly, recent research suggests that P-E fit positively affects an individual's mental well-being by satisfying fundamental psychological needs, particularly in workplace settings. Due to the similarities in organizational oversight and responsibilities between college athletes and employees, this framework may also be applicable to university sports. Employing the extended model that integrates P-E fit and BPNT within a sports context offers a detailed framework for exploring the impact of social support on student-athlete's well-being and bolsters empirical support for the model's applicability.
Finally, existing research on college athletes primarily focuses on Western contexts. There is a critical need for empirical evidence from developing countries to guide the enhancement of social support as an informal mental health resource for college athletes, especially in regions where formal support systems are underdeveloped.
To address these research gaps, this study synthesizes the main effect model and buffering model of social support, P-E fit theory, and BPNT into a comprehensive research framework (See S1 Fig). It aims to examine the impact of social support on the subjective well-being of Chinese college athletes. It explores the mediating roles of P-E fit and need satisfaction within this relationship.
