Overview

Psychometric evaluation reveals strong validity and reliability for a culturally adapted dental aesthetics scale in Indigenous adults, highlighting its utility for oral health assessments.

Key Points

  • Develop and psychometrically validate a culturally adapted version of the Psychosocial Impact of Dental Aesthetics Questionnaire (PIDAQ) for Australian Aboriginal and Torres Strait Islander adults.
  • Administered a culturally adapted short-form PIDAQ to 187 Aboriginal and Torres Strait Islander adults.
  • Evaluated dimensionality, item redundancy, network loadings, model fit, internal consistency (McDonald’s Ω), construct validity, and criterion validity using network psychometric analyses.
  • Retained two redundant but conceptually distinct item pairs (Look/Nice and Proud/Show) for cultural validity and removed the 'Worry' item due to a low network loading (0.169), yielding a 7-item questionnaire.
  • Demonstrated good model fit (χ²(4) = 6.26, p < 0.180; CFI = 1.000; RMSEA = 0.059, 90% CI: 0.000–0.140) and excellent internal consistency (McDonald’s Ω = 0.94).
  • Observed inter-item correlations between ρ = 0.520 and 0.790, alongside a directionally consistent criterion validity correlation with the SEWB scale (ρ = 0.320).
