The impact of online social support on psychological resilience and suicidal ideation among sports specialty students under academic-training dual stress: a gender-specific analysis

Background Sports specialty students in China face unique “dual stress” from academic demands and athletic training, intensified by cultural values and societal expectations. This stress contributes to elevated suicidal ideation, with limited understanding of how online social support (OSS) and psychological resilience mediate these relationships, particularly across genders. Objective To investigate the tripartite relationship among academic-training dual stress, OSS, and suicidal ideation, with psychological resilience as a mediator, and to analyze gender-specific differences. Methods A sample of 1,460 sports specialty students (60% male, 40% female) completed surveys assessing stress, resilience, OSS, and suicidal ideation. Structural equation modeling (SEM) and gender-stratified regression analyses tested mediation and moderation effects. Results Dual stress positively predicted suicidal ideation, partially mediated by reduced psychological resilience ( β = −0.220*** for males, β = −0.180*** for females). OSS buffered this relationship, with stronger moderating effects for females via emotional support ( β = −0.330***) and males via instrumental support ( β = −0.370***). Gender differences emerged in stress exposure, resilience levels, and OSS preferences. Conclusion Psychological resilience and OSS play critical roles in mitigating the impact of dual stress on suicidal ideation, with gender-specific patterns. Tailored digital interventions leveraging OSS could enhance resilience and reduce suicide risk in this vulnerable group.
