Background. The Oral Health Impact Profile (OHIP-14) is one of the most widely used instruments to assess functional and psycho-social outcomes of oral malfunction, although a vivid debate has arisen on its dimensionality and on the individual factors affecting oral health status. Aims. This research sought to examine in Study 1 the factor structure of the OHIP-14-Italian version, and in Study 2 the individual differences in terms of personality traits in OHRQoL. Method. Sample 1 (n1=852) completed the translated version of the OHIP-14, whereas Sample 2 (n2=277) fulfilled the validated OHIP-14 and the Ten Item Personality In-ventory. Results. Findings showed good fit indices for the multidimensional model and the important role played by patients’ psychological profiles in influencing OHRQoL. Discussion and Conclusions. The validity and reliability of the OHIP-14-I were provided. Together with the evaluation of patients’ psychological profiles, the instrument could help practitioners to choose the appropriate dental treatments, thus satisfying clients’ expectations and improving their OHRQoL.
