Abstract
Background: A great amount of hearing or ear-related questionnaires have been developed and validated in the past 20 years. However, a validated Dutch questionnaire specifically targeting ear pathology is missing. Objectives: The aim of the study is to develop a questionnaire about ear complaints to measure the effect of otological interventions. This questionnaire must be repeatedly applicable to all patients who present themselves with ear complaints at an ENT clinic. Material en methods: Study design: Qualitative research. Population: Patients of 12 years and older with no known learning disability. Study A: In depth interviews were conducted on: 16 patients (aged 24 to 69 years) who present themselves with ear problems at an ENT clinic. Qualitative content analysis was used to extract meaning units from verbatim transcribed patient’s reports. Study B: The meaning units were used to formulate questions for the first draft of the OQUA (OQUA1). This first draft was tested on a new group of 32 patients (aged 20 to 88 years). Study C: A list of items from the results of the first round was selected for the second version of the questionnaire (OQUA2). Moreover, some items were incorporated or modified from well-known validated questionnaires concerning the same domain during a literature study. Study D: OQUA2 was tested on a new group of 39 patients (aged 14-76 years). Results: Study A: Eight themes were obtained from the qualitative content analysis. These included: ear pain, pressure in the ear, hearing impairment, dizziness, itch, otorrhoea, tinnitus and taste disturbance. Study B: The first round of testing of OQUA among 32 patients showed that some of the descriptions made by patients during the in-dept interviews were more often selected and found more appropriate than others. These descriptions seemed to be a better representation of the particular complaints and were therefore used in OQUA2. Study C: OQUA2 consists of 47 items after item selection. Study D: Pilot-testing showed that patients experienced complaints in several domains at the same time. OQUA2 showed that the variation of the frequency in which the items were chosen was not sufficient for some of the items. Conclusion: The importance of developing a measurement instrument for ear complaints is emphasized by the fact that many patients with ear complaints had them in several domains at the same time. OQUA2 is a preliminary version, but provides a good foundation for the development of the final version of OQUA.
