The Relationship of University Students' Internet Addiction Level Through Telephone Use and 2d:4d Ratio

Abstract

Aim: To evaluate the relationship between the 2nd and 4th finger measurement ratio (2d:4d) ratio of university students' internet addiction level through phone use. Material and Method: 322 students were questioned about their demografic data, dominant extremity, and the device while using the internet. Hand width (HW), length (HL), grip strength (HGS), 2d:4d measurements were taken. Young Internet Addiction Scale (YIAS) was used for internet addiction, Smartphone Addiction Scale-Short Form (SAS) was used for smartphone addiction. Results: In men, it was determined that there was a statistically significant difference between the groups in terms of Right-Left HL, Left HGS, Right/4d, YIAS and SAS values. In addition, it was determined that the device preference, HL right, HL left, HGS left and Right/4d parameters originated from normal and dependent groups. It was determined that there was a statistically significant difference between the groups in women in terms of Left HL, Right/2d, Right/4d, Left/2d, Left/4d, Young and SAS values. It was determined that the device preference was due to individuals falling into the normal group of Left HL according to the YIAS, and the statistical difference of the Right/2d, Right/4d, Left/2d and Left/4d parameters. It was determined that there was a moderately strong negative correlation between SAS and Right/2d, Right/4d, Left/2d, Left/4d parameters in addicted men. Conclusion: The gender relations of the accepted scales regarding phone and internet addiction may be due to the length of the left hand and the movement function of the right 4d to provide control in phone use, rather than the 2d:4d finger ratios.
