Background:
Laptop use may be associated with poor health among University students. However, no psychometrically-sound instrument is available to measure biomechanical issues during laptop computer use in this population.
Objective:
To evaluate the test-retest reliability of the Student Laptop Use and Musculoskeletal Posture (SLUMP) questionnaire among undergraduate University students.
Participants:
We invited 179 undergraduate students from two Health Sciences courses at the University of Ontario Institute of Technology to participate in the study in October 2015.
Methods:
We conducted a test-retest reliability study. The SLUMP questionnaire, which includes 51 questions, was administered twice at a seven-day interval. We used weighted Kappa statistics to calculate test-retest reliability.
Results:
Ninety-one students completed the study. 72.5% of the 51 questions achieved a Kw≥0.60 with 29.4% of questions achieving a Kw≥0.80. The reliability was similar for males and females.
Conclusion:
The SLUMP offers a promising method to measure biomechanical issues during laptop use among University students.
