SOUSA, Paula Cristina Brolezi de; MENDES, Fausto Medeiros; IMPARATO, José Carlos Pettorossi  and  ARDENGHI, Thiago Machado. Differences in responses to the Oral Health Impact Profile (OHIP14) used as a questionnaire or in an interview. Braz. oral res. [online]. 2009, vol.23, n.4, pp.358-364. ISSN 1807-3107.

The objective of this study was to compare the completion rates and performance of the Brazilian version of the Oral Health Impact Profile (OHIP14) when applied as an interview or in its original self-reported form. A convenience sample of 74 adult patients was selected in a Dental Clinic (University of Araras, Brazil). One examiner administered the instrument in both formats to participants with an interval of 2 weeks between each administration. Data about dental health condition and socioeconomic status were collected and associated with total OHIP14 scores in both formats using linear regression analyses. No differences were found in the total scores and in each subscale of the OHIP14 according to the form of administration. Higher values of completion were found in the interview format. More severe impacts were recorded in the interview format than in the questionnaire format. Higher values of total OHIP-14 scores in both formats were related to the presence of dental caries. Total OHIP14 scores were not influenced by the method of administration. However, the use of the OHIP14 in the questionnaire format may result in lower completion rates and loss of data.
