Introduction
The compulsive consumption of caffeine has become a necessary ritual, especially among college students, who are frequently seen walking campus with coffee cups in hand. This habit has permeated many students’ daily lives, primarily through coffee, tea, and other caffeine-containing drinks. Many of them view its impact on their physical and mental health differently. Thus, it is reasonable to examine whether there are connections between caffeine intake and students’ everyday lives.
The proposed research aims to investigate the complex relationships among coffee consumption, subjective stress, and academic achievement. The current research field faces a gap, as most studies focus either on the health consequences of caffeine intake (Bertasi et al., 2021; Cusick et al., 2020; Huertas et al., 2019) or on people’s perceptions of its harm (Beekman et al., 2019; Samoggia et al., 2020). Another alternative is found in researchers’ investigations of stress perception among children (Richards & Smith, 2015). This comprehensive analysis aims to fill this gap by clarifying the complex and dynamic patterns of caffeine intake and shedding light on whether this ingredient can affect stress perception and academic performance.
The proposal is expected to support the hypothesis that increased consumption makes people more vulnerable to stress and worsens academic performance. The findings of this study will have broad ramifications since they will impact students’ lifestyle decisions and the development of educational policies and procedures. An appropriate methodology should be employed to ensure the study generates sufficient data to test the hypothesis. The study will rely on a quantitative approach, in which participants’ responses to the questionnaire will be analyzed statistically to make inferences about the larger population. Thus, the proposed research will provide a better understanding of whether the way stress is perceived and educational performance depend on caffeine consumption.
Background and Rationale
The thorough examination of the scholarly sources in this review reveals a complex relationship among students’ reported stress, coffee intake, and academic success. Based on the data reviewed, it appears that students are consuming increasing amounts of caffeine in their daily lives (Samoggia & Riedel, 2019). Multiple scholars support this idea and demonstrate that the consequences of increased caffeine intake represent an interesting research topic (Alfawaz et al., 2020; Czarniecka-Skubina et al., 2021). Numerous factors, such as mental health, cognitive effects, and sleep quality, appear to influence patterns of caffeine use (Nouri-Majd et al., 2022). Thus, it is critical to understand the psychological and cognitive effects of caffeine consumption and how it may affect students’ capacity to handle anxiety successfully.
Various scholars have devoted considerable effort to investigating the impact of the selected ingredient on individuals. Some of them highlight the crucial relationship between college students’ mental health and caffeine intake, providing insight into the possibility that caffeine use is inherently connected to their health status. For example, subjective conditions reveal a connection between this element and greater anxiety, depression, and sleep issues (Bertasi et al., 2021; Silva-Maldonado et al., 2022; Magalhãeset al., 2021). Such findings are widespread in the field because it is a generally accepted fact that caffeine contributes to various psychiatric and neurological disorders (Jee et al., 2020). The connections among stress, coffee, and academic achievement highlight the need for comprehensive support systems that account for these factors.
A significant body of research demonstrates that external factors can influence caffeine consumption rates. The COVID-19 pandemic affected all spheres of life, with corresponding consequences for dietary habits and broader lifestyle. In particular, the crisis led to higher coffee and tea consumption (Castellana et al., 2021; Celorio-Sardà et al., 2021). Some people increase their caffeine intake to promote socialization, alertness, and perceived health benefits (Choi, 2022).
Other individuals stipulate that this behavior is encouraged by massive advertising campaigns and the ingredient’s fatigue-reducing properties (Subaiea et al., 2019). When taken as a whole, these results highlight the intricate connections between caffeine usage and various processes in the student body and open the door to more targeted future studies in this area. Thus, a new study should be undertaken to investigate the relationships between academic performance, stress perception, and caffeine.
Methods
Subjects
The selected topic of the study denotes that the focus is placed on college students. The study design implies that two respondent groups should be selected. On the one hand, the experimental group should include active caffeine users who consume high-caffeine beverages at least twice a day. On the other hand, the control group will consist of the students who will consume lower amounts of caffeine. Individuals’ self-reports will be used to assess their consumption habits and behaviors.
In general, 100 participants (50 per group) are planned to be recruited for this research. Specific attention will also be devoted to ensuring the sample is diverse and inclusive. Thus, no exclusion criteria will be imposed based on participants’ age, gender, ethnicity, sexual orientation, or religion. This fact will allow for generalizing the obtained data for wider populations.
A convenience sampling technique will be used to establish the sample size. This strategy is appropriate because it is easy and accessible. It implies that the chief researcher reaches out to and recruits individuals they personally know who are ready to participate (Andrade, 2021). This technique is justified for this research proposal because it denotes that the chief researcher will contact individuals in advance and assign them to either the experimental or the control groups based on their caffeine consumption. Moreover, this approach will ensure the final sample size meets diversity and inclusion standards.
Procedure
As has been mentioned above, the proposed study plans to employ a quantitative approach to measure the relationship between the selected phenomena. Caffeine consumption is an independent variable, while the other two elements, academic performance and stress perception, are dependent variables. The selected methodology is significant and appropriate because it helps collect numerical data to test hypotheses and determine relationships among variables (Ahmad et al., 2019). Furthermore, multiple scholars have successfully used this approach to study caffeine intake and its consequences (Choi, 2020; Subaiea et al., 2019). This information demonstrates that it is rational to make this study follow a quantitative method.
The proposed study will consist of a few meaningful steps. First, the chief researcher will need to develop the questionnaire, format it appropriately, and upload it to a SurveyMonkey account. At this point, you will need a SurveyMonkey subscription. Second, the sample should be recruited, and all participants will be offered $50 gift cards to motivate them to enroll. During this process, the chief researcher should discover the participant’s caffeine intake volumes and assign them to one of the two groups.
Third, letters with the instructions will be sent to the recruiters’ email addresses, and they will be asked to sign and return the informed consent forms. After that, participants will receive links to the survey and will be asked to complete it within two weeks to ensure no time constraints affect the responses. Fourth, the chief researcher will have one month to analyze the data, complete the statistical tests, and write the report.
Data Analysis
The representatives of the two groups will be asked to complete the same SurveyMonkey questionnaire, which consists of two parts. The first part will focus on stress perception, which the Perceived Stress Scale will measure. This 10-item tool is the most widespread instrument to measure the selected phenomenon (NH Department of Administrative Services, n.d.).
As for the second part, it will consist of four five-point Likert-scale questions. Respondents are expected to rate their relationship to these statements according to the following rules: Strongly Disagree (1 point), Disagree (2 points), Neutral (3 points), Agree (4 points), and Strongly Agree (5 points). The questions are as follows:
- I feel confident in my understanding of the subjects.
- I am satisfied with my overall academic achievements this semester.
- My habits and behavior contribute to my academic success.
- I do not have room to improve my academic performance.
A relevant statistical test should be used to analyze whether the difference between the experimental and control groups is significant. An independent-samples t-test is suitable here, as it will help determine this information. Two individual tests will be conducted to compare the answers to the first and second parts of the questionnaire. The incorporation of this step will make the study more credible and reliable, thereby enriching the scientific field.
Schedule
Preliminary estimates indicate that the entire research will be completed within two months. Weeks 1-2 will mark the first step: developing the questionnaire and creating the SurveyMonkey account. At this stage, the chief researcher will ask another person to complete a questionnaire in test mode to ensure everything works as expected. Weeks 3-4 will be devoted to participants, as they will be asked to complete the surveys during this timeframe. Providing such a long interval is a reasonable decision because it ensures respondents can answer the questions at a convenient time. Weeks 5-8 will see the data analysis, interpretation, and discussion. The chief researcher will use this time to analyze the data and determine whether the results support the stipulated hypothesis.
Budget
The total budget for this research is $6,198, and Table 1 below provides details and explains the rationale for each figure. It is reasonable to round the figure to $6,500 to account for anticipated costs and challenges. The calculated budget is a significant advantage of the proposed project because limited resources will be needed to generate valuable and helpful knowledge. In other words, the potential scientific benefits significantly outweigh the cost of conducting this initiative. Furthermore, limited economic requirements increase the probability that the research will be undertaken. That is why it is excellent that a reasonable and feasible amount of money is considered.

Conclusion
In conclusion, this thorough analysis will bring to light the complex connections among students’ perceived anxiety levels, scholarly achievement, and caffeine use in higher education. The results will highlight the possible outcomes of coffee consumption on their perceptions and the success of their educational activities. Understanding the many factors differentiating the amount of caffeine college students consume is essential for developing customized therapies. Furthermore, the obtained results demonstrate whether it is reasonable to believe that there is a significant connection between caffeine, students’ stress perception, and their academic achievements. This study will emphasize the need for further investigation to fully understand these dynamics, which will eventually improve students’ academic performance and well-being and guide the creation of research-based educational policies and support systems.
In addition, the presented research grant proposal draws sufficient attention to the methodological details of the future study. Evidence from scholarly articles supports the presented claims and justifies the decisions made regarding participants, design, data collection, and analysis tools. The detailed consideration of this information demonstrates that it is feasible and reasonable to implement the project under analysis. Furthermore, the methods section clearly explains each step, which denotes that other scientists can easily duplicate the process to investigate other objects, events, and phenomena. Furthermore, the presented schedule and budget details demonstrate that the proposed research is feasible and financially reasonable, indicating that its implementation will yield significant benefits.
