Effects of Combined vs. Single-Source Supportive Communication from Parents and Coaches on Mental Health and Self-Regulation in Adolescent Football Players

Background: Adolescent football players are exposed to substantial psychological demands, and psychosocial support within family and sport environments has been shown to influence motivational climate, stress responses, and emotional well-being. However, the comparative effects of coordinated multi-source psychosocial support from parents and coaches versus single-source support on psychological outcomes remain insufficiently examined. Aims: to examine the effects of a multi-component psychosocial program involving parents and coaches on depression, anxiety, stress, and self-regulation in adolescent football players. Methods: A total of 60 male adolescent soccer players were recruited and randomly assigned to four groups: combined supportive communication from both parents and coaches (SCCP; n = 15), supportive communication from coaches only (SCC; n = 15), supportive communication from parents only (SCP; n = 15), and a control group (CG; n = 15). Over a 12-week intervention period, participants attended 12 sessions incorporating structured supportive communication and related psychosocial strategies. Mental health outcomes were assessed using the Depression Anxiety Stress Scale (DASS-21), while self-regulation was measured with the Self-Regulation Questionnaire (SRQ). Results: The SCCP group demonstrated the largest improvements across outcomes, with reductions observed in anxiety, depression, and stress, and significant time effects for all mental health parameters. For depression, the time effect showed a (p < 0.001; η2p = 0.93 Very large; −45.77%). Anxiety scores also indicated a significant time effect (p < 0.001; η2p = 0.81 Very large; −46.55%). Stress demonstrated an exceptionally significant time effect (p < 0.001; η2p = 0.98 Very large; −48.29%). Additionally, the self-regulation outcomes showed significant improvements, with a time effect for the Planning subscale of the SRQ indicating (p < 0.001; η2p = 0.86 Very large; +66.38%). Conclusion: The findings provide preliminary evidence that a multi-component program involving parents and coaches is associated with improvements in depression, anxiety, stress, and self-regulation among adolescent football players. These results suggest that coordinated psychosocial support across family and sport environments may contribute to adolescent athletes’ psychological well-being, although replication in other cultural and sporting contexts is required.
