简要总结
This study aims to evaluate the effects of caffeine dependence on hand reaction time and fine motor skills in university students. By comparing individuals with high and low daily caffeine intake, the research will assess whether excessive caffeine consumption is associated with impaired upper extremity performance. Reaction speed will be measured using the Nelson Hand Reaction Time Test, and manual dexterity will be assessed with the Purdue Pegboard Test.
详细描述
This observational study investigates the effects of caffeine dependence on hand reaction time and manual dexterity in young adults. Caffeine is a widely consumed psychoactive substance, and its excessive intake may influence motor and cognitive performance. University students aged 18 to 30 are recruited and divided into two groups based on daily caffeine consumption and diagnostic criteria from DSM-5/ICD-10: a high caffeine group (≥300 mg/day) and a low caffeine group (20-200 mg/day). Data are collected using the Caffeine Consumption Frequency Questionnaire and behavioral assessments conducted in a controlled laboratory environment. Hand reaction speed is measured with the Nelson Hand Reaction Time Test, while manual dexterity is assessed using the Purdue Pegboard Test. Sociodemographic data and caffeine consumption are gathered via online forms. The aim is to determine whether excessive caffeine intake is associated with changes in reaction time and fine motor skills. Statistical analyses include normality testing, group comparisons, and correlation analyses, with significance set at p<0.05. This study may provide new insights into the neuromotor effects of caffeine consumption in a university population.

结局指标
主要结局
Nelson Reaction Time Test
时间窗: Within the study duration (1 month)
The Nelson Reaction Time Test assesses visual motor response time using a dropped ruler. The score is recorded in milliseconds, with lower scores indicating faster (better) reaction time. The test does not use a fixed scale with minimum or maximum values, but typical results range from approximately 100 ms to 300 ms depending on age and condition. Higher scores indicate slower (worse) reaction time.
