Abstract
Purpose
Several studies have shown that orthodontic anomalies may affect young people’s Oral Health-Related Quality of Life (OHRQoL). The purpose the present study was to translate in the Greek language, culturally adapt and initially validate the CPQ11-14 ISF-16 for a Greek adolescent population with malocclusion.
Methods
Following relevant methodological recommendations, after translation, the comprehensiveness of the Greek version of CPQ11-14 ISF-16 (CPQ11-14 ISF-16-GR) was verified in a pilot study of 20 Greek adolescents. The main study was undertaken in a sample of 200 adolescents that presented for an initial consultation at the Postgraduate Orthodontic Clinic. Cronbach’s alpha was used to test internal consistency/reliability and Spearman’s rho for criterion validity with the Oral Health Impact Profile (OHIP-14). Forty individuals completed the same questionnaires again after 3 weeks. Test–retest reliability was assessed using Intraclass Correlation Coefficient. Statistical tests were undertaken using SPSS (v. 24, IBM Corp., NY, USA).
Results
The CPQ11-14 ISF-16-GR presented high internal consistency (Cronbach’s alpha = 0.848 > 0.70) and very satisfactory Discrimination Index (DI = 0.47 > 0.30). Moreover, the CPQ11–14ISF-16 showed excellent criterion validity with OHIP-14 (rho = 0.719, p < 0.001). Test–retest reliability was at high levels as well (ICC = 0.719, p < 0.001).
Conclusion
The CPQ11-14 ISF-16-GR exhibits satisfactory psychometric properties to continue the investigation of OHRQoL in Greek adolescents with malocclusion. Further testing of is required in a variety of environments to increase generalizability and investigate the particular characteristics of CPQ application in malocclusion cases.
