Research Objective

To investigate the relationships among sleep deprivation, caffeine consumption, stress levels, individual resilience, cognitive performance, and academic success (GPA) among college students, and to examine the moderating role of resilience in these relationships, particularly during high-stakes exam periods.

Methodology

Quantitative cross-sectional survey design. Data were collected from 300 undergraduate students using structured questionnaires assessing sleep quality (PSQI), caffeine intake, stress levels (PSS), resilience (CD-RISC), cognitive performance, and GPA. Statistical analyses included descriptive statistics, correlation analysis, multiple regression, and moderation analysis.

Discussion

The study highlights the detrimental effects of sleep deprivation on academic performance and cognitive function. It suggests that moderate caffeine consumption can offer a compensatory benefit for sleep-deprived students. Resilience is identified as a crucial protective factor, enabling students to better manage stress and maintain cognitive performance. The findings underscore the interconnectedness of these factors and their impact on student well-being and academic success.

Key Findings

- Sleep deprivation was negatively correlated with cognitive performance and GPA.
- Caffeine consumption was positively associated with cognitive performance.
- Resilience moderated the relationship between stress and cognitive performance, acting as a buffer against negative outcomes.
- Stress levels were negatively associated with cognitive performance and GPA.
- Caffeine consumption was found to mitigate the negative impact of sleep deprivation on GPA.

Conclusion

Sleep deprivation significantly impairs cognitive performance and GPA, while resilience plays a vital role in buffering the negative effects of stress. Moderate caffeine consumption may offer some benefits. Educational institutions should focus on promoting healthy sleep habits, stress management, and resilience-building strategies to enhance student well-being and academic achievement.

Fact Check

- The study collected data from n=300 undergraduate students. (Confirmed in Abstract and Methodology)
- Mean age of participants was 20.5 years. (Confirmed in Table 1)
- Sleep deprivation was negatively correlated with cognitive performance with r = -0.70. (Confirmed in Table 2)
