Background: Parents' perceptions of their 8-17-year-old children's oral health status were assessed using a sample from diverse dental clinics in Greater Los Angeles County to identify constructs for a survey instrument.

Methods: Focus groups with 29 parents or guardians were conducted to identify themes that informed development of survey items. The draft items were administered to a different group of 32 parents or guardians in cognitive interviews, and revised for subsequent field-testing.

Results: Thematic and narrative analyses were performed after the focus groups and key lay-oriented dimensions were uncovered, notably the relationship between oral health, systemic health and the life course. In the cognitive interviews, parents entered multiple responses to questions related to the look of their child's teeth, and their overall perception of tooth color. Parents also assessed their child's fear or discomfort with the dental experience, and other social and psychological concerns related to oral health status. The temporal dimensions of certain items were specified; for example, oral pain and mood items were revised to include duration of the symptom or mood state. As parents tended to confuse oral health maintenance and prevention, these two related concepts were separated into two items. Based on the qualitative work, we revised items in preparation for a field test.

Conclusions: As a PRO measurement study, qualitative research informed a field test survey to assess factors associated with oral health status and the individual's perceptions and subjective views of these constructs for eventual item development for epidemiological and clinical use.

Child and adolescent perceptions of oral health over the life course.

Qual Life Res 2015 Nov 3;24(11):2739-51. Epub 2015 Jun 3.

Division of Public Health and Community Dentistry, School of Dentistry, University of California, Los Angeles, Los Angeles, CA, 90095, USA.

Purpose: To elicit perceptions of oral health in children and adolescents as an initial step in the development of oral health item banks for the Patient-Reported Oral Health Outcomes Measurement Information System project.

Methods: We conducted focus groups with ethnically, socioeconomically, and geographically diverse youth (8-12, 13-17 years) to identify perceptions of oral health status. We performed content analysis, including a thematic and narrative analysis, to identify important themes.

Results: We identified three unique themes that the youth associated with their oral health status: (1) understanding the value of maintaining good oral health over the life course, with respect to longevity and quality of life in the adult years; (2) positive association between maintaining good oral health and interpersonal relationships at school, and dating, for older youth; and (3) knowledge of the benefits of orthodontic treatment to appearance and positive self-image, while holding a strong view as to the discomfort associated with braces.

Conclusions: The results provide valuable information about core domains for the oral health item banks to be developed and generated content for new items to be developed and evaluated with cognitive interviews and in a field test.
