Drivers with medical conditions may need to demonstrate their fitness by participating in clinical and on-road assessments. Scores from the clinic-based occupational therapy-drive home maze test (OT-DHMT) can contribute to fitness-To-drive recommendations. The OT-DHMT is a short, timed test that has previously been shown to be valid and reliable, and norms are available for completion with a driver's dominant hand. Following stroke or trauma, many drivers need to complete assessments and resume driving using their nondominant hand. The validity of a person's OT-DHMT score when completed with a nondominant hand is unknown. This study investigated if a person's OT-DHMT score time requires adjustment when completed with a nondominant hand. The OT-DHMT was administered with a convenience sample of 148 community-dwelling participants, aged 21-81 years (M = 48.6, SD = 19.38) using both their dominant and nondominant hands, in a random order. OT-DHMT score times were significantly faster when using dominant (M = 15.73) compared with nondominant (M = 17.64) hand, d = 1.91 [confidence interval (CI) 1.13, 2.69], t = 4.84, P < 0.01. Employing a generalized weighted least squares regression model indicated that multiplying a driver's nondominant hand time by 0.833 s for drivers aged ≤60, and by 0.929 s for drivers aged 61+ can approximate dominant hand completion times. The OT-DHMT has been validated for use with people using their nondominant hand. Time adjustments are required for people using their nondominant hand when completing the OT-DHMT, and a larger adjustment is required for people aged ≤60 reinforcing previous findings that younger people have faster OT-DHMT completion times. © 2020 Lippincott Williams and Wilkins.
