Outcome Measures
Primary Outcomes (5)
Demographic Information Form
Collects participant data including age, sex, height, weight, and education level.
day 1
Smartphone Usage Questionnaire
This form assesses daily smartphone usage duration, body posture during use, headache frequency, and associated symptoms. It also includes questions on strategies to reduce smartphone use and ergonomic habits.
day 1
Smartphone Addiction Scale - Short Form (SAS-SF)
Developed by Kwon et al., this 10-item, six-point Likert scale evaluates participants' risk of smartphone addiction. Scores range from 10 to 60, with higher scores indicating higher addiction risk. Cut-off points are 31 for males and 33 for females.
day 1
New York Posture Rating Chart
This tool evaluates posture across 13 body segments. Each item is scored as 1 (severe deviation), 3 (moderate deviation), or 5 (normal posture), with total scores ranging from 13 to 65. Higher scores reflect better postural alignment.
day 1
Visual Analog Scale (VAS)
Used to assess the severity of headaches. Participants indicate their perceived pain intensity on a 10 cm horizontal line, where 0 = "no pain" and 10 = "worst imaginable pain." They will rate their headache intensity both during and after smartphone use.
day 1
