Background/Aim. Among numerous sociodental indicators the Oral Impacts on
Daily Performance (OIPD) is one of the most broadly applied. The aim of this
study was to develop and test psychometric properties of a Croatian version
of OIDP scale. Methods. The OIDP instrument was translated from English to
Croatian in a forward-backward method. The Croatian version was tested for
reliability, construct validity and responsiveness on a sample of 702
participants (255 men), aged 18-86 years. Results. Internal consistency of
Croatian version of the OIDP was acceptable (alpha = 0.80) and 69.4% of the
examinees had oral impacts relating to one or several performances. The most
frequently affected performance was eating (53.7%). The test-retest
reliability was high (r = 0.99; 95% CI: 0.97-0.99), the mean difference
between the OIDP summary scores in two-week interval was not statistically
significant. In construct validity testing there was statistically
significant correlation between OIDP and self-assessed general and oral
health, somatisation, depression and Oral Health Impact Profile ranging from
0.157 to 0.516. Responsiveness was confirmed by a significant reduction of
oral impacts on daily performances in subjects before and after treatment of
acute dental pain (p < 0.001). Conclusion. The Croatian OIDP index showed
good psychometric properties in terms of construct validity, internal
consistency, test-retest reliability and responsiveness confirming its
appropriateness for use among Croatian population.
