Exploratory and confirmatory factorial analysis of the OHIP-Edent instrument

Abstract

Several instruments have been used to measure oral healthrelated quality of life (OHRQoL). The Oral Health Impact Profile (OHIP) questionnaire was based on the concept that sequential events related to oral diseases can cause discomfort, functional limitations and consequently, result in dysfunctions and even disabilities. There are few studies in the literature that structurally analyze the instruments to verify whether they measure the requirements to which they were designed to. The objective of the study was to evaluate the internal structure of the OHIP-Edent questionnaire. The OHIP-Edent was administered to 54 edentulous patients' wearers of conventional complete dentures. For structural analysis, an exploratory factorial analysis (EFA) was carried out. After determining the internal consistency of the model (Cronbach's alpha = 0.88), the fit was checked using the root mean square error approach (value 0.04), the comparative fit index (value 0.982) and the Tucker-Lewis index (value 0.976).

GOHAI and OHIP‐EDENT Evaluation in Removable Dental Prostheses Users: Factorial Analysis and Influence of Clinical and Prosthetic Variables

“…This instrument is able to detect changes in the quality of life of complete denture wearers after the insertion of new prostheses, showing good responsiveness. 28,29 These questionnaires were validated in Brazilian Portuguese and extensively used in research to assess satisfaction with dental prostheses and the quality of life of edentulous patients.…”

“…Participants’ answers were considered individually, and two structured models with grouping of questions were used. In the model proposed by Sousa et al, 28 questions 1, 5, 10, and 11 estimate the domain of “chewing complaints”; questions 8, 9, 12, 13, and 14 estimate “psychological discomfort and problems;” questions 15 to 19 estimate “social disability;” and questions 2, 3, 4, 6, and 7 estimate “oral pain and discomfort.” In the model proposed by Possebon et al, 29 questions 1, 2, 3, 4, 5, 6, 7, 10, 11, and 12 to estimate “physical impact;” questions 8, 9, 13, and 14 estimate “psychological impact;” and questions 15 to 19 estimate “social impact.”…”

Reliability and validity of the Turkish version of oral health impact profile for edentulous subjects

“…The current study measured both construct and convergent validity of the OHIP-EDENT-T. Previous studies evaluating the OHIP-EDENT used different methodologies for assessing validity, the exploratory factor analysis being the most common (17,20,21,35,36). The main purpose of factor analysis is to facilitate the understanding and interpretation of the relationships between numerous variables considered to be correlated by reducing them to smaller number of basic dimensions.…”

Sense of Coherence mediates the association between temporomandibular disorders and quality of life

“…Exploratory and confirmatory factor analyses were performed for the construction of the latent variables of OHRQoL, QoL, and SOC. Exploratory factor analysis (EFA) revealed three domains for OHRQoL, labeled as “physical,” “social,” and “psychological” domains (Possebon, Faot, Machado, Nascimento, & Leite, ; Supporting Information Appendix ). To avoid misspecification of the model, which requires a latent variable with at least four observed variables to perform all models estimates, the “social” domain was parceled in two different indicators.…”
