Overall, information on the DHI's content validity was doubtful and of low quality. The rating for relevance was indeterminate and the quality of evidence could not be graded. As for comprehensiveness, findings were rated as inconsistent and the overall quality of evidence was low. Comprehensibility was sufficient with low quality evidence. Moderate evidence was found for inconsistent structural validity (6 studies were rated as inadequate, 6 as adequate, and 2 as very good). Moderate evidence was also found for borderline sufficient construct validity, and borderline sufficient responsiveness. Internal consistency could not be assessed as structural validity was inconsistent. Test-retest reliability of the DHI total score was rated as inadequate or doubtful. Reliability of the DHI total score was sufficient (intraclass correlation coefficient values for the DHI total score ranged from 0.81 to 0.99) with a low quality of evidence. Overall measurement error was indeterminant and quality of evidence could not be graded. Future research is required as the current evidence for several measurement properties is suboptimal.
