Measurement Equivalence of "Touch-Screen" versus "Paper-Based" Assessments of OHRQoL: A Randomized Crossover Trial.

ABSTRACT:

Purpose

To determine the measurement equivalence of computer touch screen assessment (CTSA) and paper based assessment (PBA) of the oral health impact profile (OHIP-14).

Patients and methods

A randomized crossover trial was conducted. Sixty participants were randomized to either i) Arm A: completed CTSA then PBA of OHIP-14, or ii) Arm B: PBA and then CTSA of OHIP-14 within the same day. User preference and time taken to complete the assessments were recorded. Agreement between CTSA and PBA was determined using directional difference (DD), absolute difference (AD), and intraclass correlation coefficient (ICC).

Results

There was no significant difference in CTSA and PBA OHIP-14 scores (P>0.05). The magnitude of the DD in scores between assessment methods was smal
