The Grooved Pegboard Test (GPT) is widely adopted to evaluate manual dexterity, it presents normative data but the test is influenced by different factors. The influence of time spent on smartphones has not been considered before, for this reason, the objective of this study was to evaluate if smartphone use influences the time to complete the GPT. A total of 38 (21 women; 17 men) young adults 20.7 (1.5) years participated in the study. The time spent on the smartphones during the last seven days was recorded through the device itself and the GPT performance was measured. A correlation analysis between the time spent on the smartphone and GPT was performed while the t-test was adopted to evaluate gender differences. No statistically significant differences were detected between men and women in the time to complete the GPT (p = 0.20) and in the time spent on the smartphone (p = 0.87). The GPT and the time spent using the smartphone were not correlated (r = 0.044, p = 0.78). The time spent on the smartphone by young adults does not influence the time to complete the GPT, indicating that smartphone use does not influence measures of manual dexterity.

花在智能手机上的时间与年轻人的手动灵活性无关

Grooved Pegboard Test (GPT) 被广泛用于评估手动灵活性，它提供了规范的数据，但测试受不同因素的影响。以前没有考虑过使用智能手机的时间的影响，因此，本研究的目的是评估智能手机的使用是否会影响完成 GPT 的时间。共有 38 名（21 名女性；17 名男性）20.7（1.5）岁的年轻人参与了这项研究。通过设备本身记录过去 7 天在智能手机上花费的时间，并测量 GPT 性能。在智能手机上花费的时间与GPT之间进行相关性分析，同时采用t检验来评估性别差异。在完成 GPT 的时间上，男性和女性之间没有发现统计学上的显着差异（p = 0. 20）和在智能手机上花费的时间（p = 0.87）。GPT 和使用智能手机的时间不相关（r = 0.044，p = 0.78）。年轻人在智能手机上花费的时间不会影响完成 GPT 的时间，这表明智能手机的使用不会影响手动灵活性的测量。
