The Oral Health Impact Profile-14:: a unidimensional scale?

Abstract

The aim of this study was to investigate the dimensional structure of the Oral Health Impact Profile-14: (OHIP-14). Data was obtained from studies carried out in Rio de Janeiro (N = 504) and Carlos Barbosa (N = 872), in the State of Rio Grande do Sul, Brazil. Exploratory factor analysis (EFA) was performed to identify the latent dimensions of the OHIP-14. Confirmatory factor analysis (CFA) was carried out of both samples to compare the one-dimensional structure found by the EFA and the proposed three-dimensional structure. This factorial structure was assessed using goodness-of-fit indices. In the Rio de Janeiro study, the eigenvalue was 9.2 and this one factor explained 65.6% of total variance, while in the Carlos Barbosa study the eigenvalue was 7.9 and this one factor explained 56.6% of variance. CFA indicated an adequate fit of the one-factor model for the Rio de Janeiro study (RMSEA = 0.04; CFI = 0.98; TLI = 0.98) and for the Carlos Barbosa study (RMSEA = 0.05; CFI = 0.97; TLI = 0.97). Our findings suggest that the OHIP-14 measures one single construct.

Validation of the English-language version of 5-item Oral Health Impact Profile

“…OHIP5 has at least one indicator for each of the four dimensions, supporting its content validity. A unidimensional model fit OHIP5 data well in our population, a finding similar to OHIP14 scores in another population [32]. This means while perceived oral health is multidimensional from a conceptual perspective, when using OHIP5, a single score can summarize the various aspects of OHRQoL with one total score.…”

Risk factors, hyposalivation and impact of xerostomia on oral health-related quality of life

“…The highest impact was detected for the domains of psychological discomfort, psychological incapacity and physical pain. Nevertheless, the utility of the OHIP-14sp in detecting changes in the different sub-scales has been questioned; 34 thus, this result should be regarded with caution. According to Hopcraft et al, patients with severe xerostomia are 2.3 to 4.9 times more likely to have a negative experience and negative impact on quality of life.…”

Impact of the severity of chronic periodontal disease on quality of life

“…The increasing availability of instruments for psychological assessment has enabled studies of the impact of oral health on individual QoL. One such instrument, the Oral Health Impact Profile (OHIP-14), is very frequently used (8,9,12,13,15,19,22,26,(29)(30)(31)(32) and has adequate validity and sensitivity for health-related research. The OHIP-14 was selected for this study because it is a good indicator of self-perception and individual feelings about oral health and because it can assess the adverse aspects of the relation between oral health and QoL.…”
