Students with Digital Addiction

Evaluation of muscle strength, Young Internet Addiction Test-Short Form (YIAT-SF), International Physical Activity Questionnaire-Short Form (IPAQ-SF) and SF-12

The Lafayette muscle strength measurement device is a digital dynamometer used to objectively and numerically assess maximum isometric muscle strength. The device provides a more precise and repeatable measurement than manual muscle testing, providing a reliable method for assessing muscle strength. It can be used with various attachments for different muscle groups and is frequently used in rehabilitation, performance analysis, and clinical research. A high score indicates high muscle strength.

The IPAQ-SF is an internationally standardized self-report questionnaire developed to determine individuals' physical activity levels. This seven-question short form assesses **walking, moderate-intensity, and vigorous-intensity physical activities**, as well as **sitting time**, over the past seven days. Using participant-reported duration and frequency data, physical activity level is calculated in **MET-minutes/week**. Its rapid administration and applicability to large populations make it a valid and reliable measurement tool for population-based research and clinical trials. Participants can use physical activity levels of Low, Moderate, or High based on their MET score, depending on the day and time. A higher MET value indicates a higher level of physical activity.

Quality of Life will assess with SF-12. The SF-12 is a short self-report questionnaire developed to assess individuals' general health status and quality of life. A shortened version of the SF-36, this scale consists of 12 questions and assesses physical and mental health components (Physical Component Summary (PCS) and Mental Component Summary (MCS). Due to its short administration time and practicality, it is frequently used in clinical research, community health studies, and rehabilitation. A high score indicates a high level of life quality. Scores range from 0 to 100. 0 points: Worst health status and 100 points: Best health status.

Higher scores indicate better physical or mental health. Lower scores indicate worse health status.
