To determine the measurement equivalence of computer touch screen assessment (CTSA) and paper based assessment (PBA) of the oral health impact profile (OHIP-14).
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).
There was no significant difference in CTSA and PBA OHIP-14 scores (>0.05). The magnitude of the DD in scores between assessment methods was small for overall scores and all domains (<0.3). The AD in OHIP-14 scores was small (~6% for overall score, between 8-16% for domains). Agreement between CTSA and PBA was high (ICC=0.9; 95% CI=0.8-0.9) for overall OHIP-14 scores, but ICC values varied across domains. Most (78%) preferred CTSA. There was no significant difference in time taken to complete assessments (=0.09). Regression analyses did not identify any significant socio-demographic factor associated with absolute difference between CTSA and PBA scores.
There is equivalence of measurements in OHRQoL assessments from CTSA and PBA, and the time taken to complete assessment by either means is similar. There is a greater preference for CTSA. This has implications to support the use of CTSA in OHRQoL assessments.
确定口腔健康影响程度量表（OHIP-14）的计算机触摸屏评估（CTSA）和纸质评估（PBA）之间的测量等效性。
进行了一项随机交叉试验。60名参与者被随机分为两组：i）A组：先完成OHIP-14的CTSA评估，然后进行PBA评估；ii）B组：在同一天内先进行OHIP-14的PBA评估，然后进行CTSA评估。记录用户偏好和完成评估所需的时间。使用方向差异（DD）、绝对差异（AD）和组内相关系数（ICC）来确定CTSA和PBA之间的一致性。
CTSA和PBA的OHIP-14评分无显著差异（>0.05）。总体评分和所有领域的评估方法之间的评分DD幅度较小（<0.3）。OHIP-14评分的AD较小（总体评分为~6%，各领域为8 - 16%）。OHIP-14总体评分的CTSA和PBA之间的一致性较高（ICC = 0.9；95% CI = 0.8 - 0.9），但ICC值在各领域有所不同。大多数（78%）更喜欢CTSA。完成评估所需的时间无显著差异（=0.09）。回归分析未发现任何与CTSA和PBA评分之间的绝对差异相关的显著社会人口统计学因素。
CTSA和PBA在口腔健康相关生活质量评估中的测量具有等效性，并且两种方式完成评估所需的时间相似。对CTSA的偏好更高。这对于支持在口腔健康相关生活质量评估中使用CTSA具有重要意义。
