3.1. Mediation Analysis
The first step in the mediation analysis involved testing the measurement model, which included social support (companion, affirmative evaluation, intimacy, emotive support, and instrumental support as latent variables), basic psychological needs (autonomy needs, competence needs, and relatedness needs as latent variables), and prosocial behavior (altruism, rule compliance and public welfare, relatedness, and trait prosociality as latent variables). The model exhibited good fit indices, with χ2/df = 2.59, CFI = .972, TLI = .960, RESMA [90% CI] = .064 [.052, .075].
In the second step, we examined the direct predictive model, specifically investigating the relationship between gratitude and prosocial behavior. The model exhibited good fit indices, with χ2/df =3.05, CFI = .981, TLI = .962, RESMA [90% CI] = .073 [.048, .098]. he results revealed a significant direct effect of gratitude on prosocial behavior (β = .25, p < .001). These findings indicate that higher levels of gratitude were associated with greater subsequent engagement in prosocial behavior among adolescents.
The third step involved testing the mediating role of social support and basic psychological needs in the relationship between gratitude and prosocial behavior. The model was shown in
Figure 1, which exhibited good fit indices, with χ2/
df =2.50, CFI = .970, TLI = .957, RESMA [90% CI] = .062 [.052, .073]. The results indicated that gratitude positively predicts social support (β = .41,
p < .001) and basic psychological needs (β = .18,
p < .001), social support positively predicts basic need satisfaction (β = .17,
p < .001) and prosocial behavior (β = .23,
p < .001), basic psychological needs positive predicts prosocial behavior (β = .35,
p < .001). These findings suggest that social support and basic psychological needs partially mediated the relationship between gratitude and prosocial behavior among adolescents. Furthermore, the results demonstrated a chain-like mediation effect, wherein social support influenced basic psychological needs, which in turn predicted prosocial behavior.
4. Discussion
The present study aimed to examine the influence of gratitude on adolescent prosocial behavior, with a specific focus on the mediating roles of social support and basic psychological needs. Our findings revealed that gratitude at one time point positively predicted subsequent prosocial behavior among adolescents, indicating the importance of gratitude in promoting positive social engagement. Moreover, social support and basic psychological needs played mediating roles in the relationship between gratitude and prosocial behavior, and a chain mediation effect was observed.
Consistent with previous research [
3,
12], our study supports the positive association between gratitude and prosocial behavior among adolescents. Gratitude serves as a positive emotion that broadens individuals’ thoughts and actions, leading to increased prosocial behavior [
11]. By recognizing and appreciating the benefits received from others, grateful adolescents develop empathy and perspective-taking abilities, which enhance their willingness to help others [
8]. This finding emphasizes the importance of cultivating gratitude in interventions and programs aimed at promoting prosocial behavior among adolescents.
Social support was found to mediate the relationship between gratitude and prosocial behavior. Adolescents who perceive positive social environments and have close relationships are more likely to engage in prosocial behaviors [
16]. The presence of supportive resources in the social environment contributes to the satisfaction of basic psychological needs, such as competence and relatedness [
32]. Our study highlights the role of social support as a mechanism through which gratitude influences prosocial behavior, underscoring the importance of fostering supportive social networks and relationships for promoting prosociality among adolescents.
Furthermore, our study demonstrated that basic psychological needs mediated the relationship between gratitude and prosocial behavior. Gratitude enhances individuals’ satisfaction of basic psychological needs by promoting feelings of competence, autonomy, and relatedness [
11,
23]. Adolescents who experience higher levels of gratitude are more likely to engage in prosocial activities, as their needs for competence, autonomy, and relatedness are fulfilled [
29]. This finding highlights the significance of addressing adolescents’ basic psychological needs in interventions targeting prosocial behavior promotion.
Importantly, our study identified a chain mediation effect, suggesting that social support and basic psychological needs sequentially mediate the relationship between gratitude and prosocial behavior. Gratitude not only directly influences prosocial behavior but also exerts its effects through the satisfaction of basic psychological needs, which is facilitated by social support. This finding provides a nuanced understanding of the underlying mechanisms through which gratitude operates to promote prosocial behavior among adolescents. Interventions that focus on enhancing gratitude, social support, and basic psychological needs may have a cumulative effect on fostering prosocial behavior.
While our study contributes to the literature on gratitude, social support, basic psychological needs, and prosocial behavior among adolescents, it is important to acknowledge several limitations. First, the study relied on self-report measures, which are subject to biases and limitations in capturing actual behavior. Future research should incorporate behavioral measures or observational data to provide a more comprehensive understanding of prosocial behavior. Second, the study utilized a longitudinal design, allowing for the examination of temporal relationships, but causal interpretations should be made cautiously. Experimental studies or intervention designs are needed to establish causal effects. Third, our sample consisted of adolescents in the high school setting, limiting the generalizability of findings to other age groups or contexts. Future research should explore the role of gratitude, social support, and basic psychological needs in diverse populations and developmental stages.
Despite these limitations, the present study holds important implications for both research and practice. It advances our understanding of the processes underlying the relationship between gratitude and adolescent prosocial behavior by identifying social support and basic psychological needs as mediating factors. These findings highlight the complex interplay between gratitude, social support, and basic psychological needs in promoting prosocial behavior among adolescents.
From a theoretical standpoint, our study contributes to the field of positive psychology by providing empirical evidence for the mechanisms through which gratitude influences prosocial behavior. The integration of the Broaden and Build Theory of Positive Emotions [
9,
10] and self-determination theory [
19] offers a comprehensive framework for understanding the psychological processes underlying prosocial behavior. By identifying the mediating roles of social support and basic psychological needs, our study elucidates the pathways through which gratitude operates to foster prosocial behavior among adolescents.
Practically, our findings have important implications for interventions and programs aimed at promoting prosocial behavior among adolescents. By recognizing the positive impact of gratitude, practitioners can design interventions that cultivate gratitude as an emotional skill among adolescents. Strategies such as gratitude journals, gratitude letters, or gratitude exercises can be incorporated into educational settings, counseling programs, or community initiatives. Moreover, fostering supportive social environments and promoting the satisfaction of basic psychological needs should be considered in interventions targeting prosocial behavior. Strengthening social support networks and providing opportunities for adolescents to develop and maintain positive relationships can enhance their sense of belonging and encourage prosocial behaviors.
Additionally, our study sheds light on the role of social support and basic psychological needs in the context of prosocial behavior. The findings underscore the importance of considering the broader social and psychological factors that influence adolescents’ engagement in prosocial behaviors. Practitioners and educators can create environments that foster social support and promote the satisfaction of basic psychological needs by implementing peer mentoring programs, cooperative learning activities, and inclusive school climates. By addressing these factors, interventions can provide a comprehensive approach to cultivating prosocial behavior among adolescents.
Despite the contributions of this study, there are several avenues for future research. Firstly, further investigations should explore the underlying mechanisms through which social support and basic psychological needs influence prosocial behavior. Examining specific cognitive, emotional, and motivational processes can provide a more nuanced understanding of these relationships. Secondly, longitudinal studies with multiple time points can elucidate the long-term effects of gratitude, social support, and basic psychological needs on prosocial behavior. Understanding the developmental trajectories and stability of these variables can inform the design of interventions at different stages of adolescence. Lastly, the cultural and contextual factors that may influence the relationships among gratitude, social support, basic psychological needs, and prosocial behavior warrant further exploration. Comparative studies across diverse cultural backgrounds can enhance our understanding of the universality or cultural specificity of these associations.
In conclusion, our study highlights the positive influence of gratitude on adolescent prosocial behavior and uncovers the mediating roles of social support and basic psychological needs. By recognizing the importance of gratitude and its underlying mechanisms, interventions and programs can be tailored to foster prosocial behavior among adolescents. By creating supportive social environments and addressing adolescents’ basic psychological needs, practitioners and educators can contribute to the development of a positive and compassionate society. Further research is needed to deepen our understanding of these processes and their cultural implications.
