Adaptación transcultural del instrumento Orthognathic Quality of Life questionnaire al español para el estudio de la calidad de vida de pacientes con anomalías dentofaciales. Fase I

Introduction:

Orthognathic surgery is a therapeutic option that seeks parameters of symmetry, masticatory function, breathing, and improves the emotional state of patients with dentofacial anomalies. The questionnaire Orthognathic Quality of Life Questionnaire (OQLQ) allows to make a subjective evaluation and the level of quality of life before and after surgery, so it is necessary to perform the translation into Spanish and the cultural adaptation to the Colombian context.

Methods:

After the authorization of the original author, direct translations were made obtaining a preliminary version, reverse translations and a pilot test was accomplished with 15 Colombian patients over 16 years of age with a dentofacial anomaly who attended the San José hospital in Bogotá. The methodology of the quality group of the European Organization for Research and Treatment of Cancer (EORTC) was applied to ensure that the Spanish version of the scale is conceptually equivalent to the original.

Results:

The direct translations were consistent, however, adjustments were made to obtain the preliminary version; the inverse translations were similar to the original version of the scale. The pilot test, carried out on a heterogeneous sample of 15 patients led to the adjustment of the syntax of one item. In this way, the Spanish version of the questionnaire was obtained.

Conclusions:

The realization of this study allowed the adaptation of an understandable questionnaire in the Colombian context, guaranteeing a linguistic and conceptual equivalence between this version and the original version.
