Abstract

The current study examines the connection between caffeine intake and its effects on focus, anxiety, and sleep quality across generations. The Caffeine Expectancy Questionnaire (CaffEQ), the Hamilton Anxiety Rating Scale (HAM-A), a Sleep Quality Scale, and a Concentration Questionnaire were used to evaluate 106 participants from three age cohorts: Generation Z, Millennials, and Generation X/Boomers. The descriptive statistics showed somewhat above-average scores for concentration and sleep quality, along with moderate levels of anxiety and caffeine expectation. Caffeine consumption was found to have a weak but statistically significant positive link with concentration (r=.192, P=.049) and sleep quality (r=.204, P=.036), but no significant relationship with anxiety (r=.022, P=.824), according to correlation analysis.

According to the results of the ANOVA, there is a significant difference in the quality of sleep between generations (F(2,103)=10.172, P=.000), with older persons in Generation 3 reporting the best quality of sleep. But there were no appreciable differences in caffeine intake, anxiety, or focus between generations. According to these results, caffeine may have a slight beneficial effect on sleep and focus, but its effects don't seem to differ significantly depending on the generation. The study emphasizes how crucial it is to comprehend caffeine consumption habits at the individual and generational levels and how they affect mental and cognitive health.
