OBJECTIVE Investigating the usability of the Dutch version of the Oral Health Assessment Tool (OHAT-NL) with informal caregivers of community-dwelling older people with suspected dementia, without specific training. MATERIALS AND METHODS In accordance with guidelines for establishing the cultural equivalency of instruments, the OHAT was translated into Dutch. Fifteen informal caregivers of community-dwelling older people with suspected dementia and, as a reference standard, a dentist assessed the oral health of the older people using the OHAT-NL. The caregivers' scores were compared with the dentist's scores. The usability of the OHAT-NL was rated on a 10-point scale (0 = incomprehensible, and 10 = very user friendly) and investigated further through short structured interviews. RESULTS There were differences between the dentist's and caregivers' assessments of the individual categories of the OHAT-NL. The specificity of the need to visit an oral health care professional was 100.0%, while the sensitivity was 78.6%. The informal caregivers concluded that the tool made them more aware of different aspects of oral health. The tool was rated with a mean score of 7.7 (SD 1.7). CONCLUSION The OHAT-NL could be a useful tool for informal caregivers without specific training to indicate whether the person they care for should visit an oral health care professional.
