Background: Social media addiction, one of the behavioural addictions, is a significant predictor of job performance. It has also been posited that individuals whose fundamental requirements (e.g., sleep) are not sufficiently met and who lack adequate support (e.g.,perceived social support) are incapable of effectively harnessing their potential. The primary objective of this study is to examine the mediating effects of sleep disorder and perceived social support on the relationship between social media addiction and job performance. Furthermore, it seeks to explore the moderating effects of perceived social support on sleep disorders and job performance. Methods: The data were collected through the questionnaire method, and data analysis was performed using SPSS 26.0. Moreover, statistical analysis encompasses correlation analysis, mediation, and moderation analysis. The data were gathered from 488 healthcare professionals (57.2% female), whose ages ranged from 24 to 56 years (Meanage ± SD = 37.86 ± 6.71), using a convenience sample approach. Results: The results revealed significant relationships between social media addiction, job performance, perceived social support, and sleep disorder. The findings indicate that social media addiction negatively predicts job performance (β =−0.11, p < 0.05). Sleep disorder (effect size =−0.02, 95% CI = [−0.04, −0.00]) and perceived social support(effect size = −0.01, 95% CI = [−0.02, −0.00]) mediate this relationship. Furthermore, perceived social support moderates the pathway between sleep disorder and job performance (index of moderated mediation: −0.0040, 95% CI = [−0.0070, −0.0010]). Conclusions: This study suggests that social media addiction negatively affects job performance through sleep disorders and perceived social support among healthcare professionals. The study’s findings are significant, as they suggest that treatments aimed at alleviating sleep disorders and enhancing perceived social support among medical workers may improve their job performance.
