Area of Science:

  • Musculoskeletal health
  • Student health
  • Psychometrics

Background:

  • Upper extremity symptoms are common in students due to computer use and other activities.
  • Existing measures lack psychometric soundness for assessing student role function in research.

Purpose of the Study:

  • To develop and validate a reliable and valid measure of health-related student role function.
  • To create a tool for research on upper extremity disorders in student populations.

Main Methods:

  • Developed a 10-item scale based on student and clinician input.
  • Administered the scale to 193 undergraduates with a 1-month follow-up.
  • Assessed internal consistency, ceiling effects, validity (convergent, discriminant), and responsiveness.

Main Results:

  • The scale demonstrated high reliability (Cronbach's alpha = 0.87).
  • It showed a reduced ceiling effect compared to a generic measure, indicating better detection of limitations.
  • The measure exhibited convergent and discriminant validity and was responsive to self-perceived functional changes.

Conclusions:

  • The developed student health-related role functioning measure is reliable, valid, and responsive.
  • It is suitable for research investigating upper extremity symptoms in students.
