Abstract(s)
To perform a validation of the Geriatric
Oral Health Assessment Index (GOHAI) for
complete denture wearers and present a proposal
for estimation of perceived oral health. This is a
cross-sectional study with non-probabilistic
sampling. A total of 211 subjects with a mean age
of 62 5 (s.d. = 11 4) years participated, being 169
female. The GOHAI was applied in a personal
interview. The construct/convergent/discriminant
validity was tested using structural equation
modelling. Confirmatory factor analysis was used
to verify the fit of three proposals of the GOHAI:
three-factor, one-factor and second-order
hierarchical models. The stability of the models
was evaluated in independent samples. The threefactor
model presented an inadequate fit, and
items 3, 4 and 9 were removed. The new structure
presented an acceptable fit and strong invariance
in independent samples. The convergent,
discriminant validity and internal consistency
were below adequate. The one-factor model
presented an adequate fit to the sample.
Convergent validity was compromised. A strong
invariance of the one-factor model was observed.
To calculate the overall scores of the GOHAI
factors (three-factor model) or of the oral health
perception (one-factor model), a matrix of
regression weights for each item in the model was
presented as a suggestion. We found an adequate
fit of the both structures of the GOHAI for denture
wearers, but the three-factor structure was more
parsimonious. We suggested considering the
weights of the regression model to calculate the
overall score of perceived oral health or of its
factors in different samples.
