NCT04863170

Brief Summary

The aim of this study was to develop a Spanish version of the Orthognathic Quality of Life Questionnaire (OQLQ) that is conceptually equivalent to the original questionnaire, as well as acceptable, reliable, valid, and responsive for use in Chilean patients with dentofacial deformities.The cross cultural adaptation process was carried out according to the recommended standard methodology with direct and back-translation.

Outcome Measures

Primary Outcomes (6)

  • Metric properties of Orthognathic Quality of Life Questionnaire (OQLQ): Reliability

    To measure this metric property, internal consistency and test-retest reproducibility were assessed. The orthognathic quality of life questionnaire (OQLQ) was applied twice, with four weeks between tests. To assess reliability, the internal consistency was estimated by the Cronbach alpha coefficient, and the test-retest reproducibility was estimated by the intraclass correlation coefficient. The orthognathic quality of life questionnaire is a condition specific instrument for assessment oral health quality of life in dentofacial deformities patients 22 ítems values: min = 0 / max = 88 higher scores mean a worse outcome

    4 weeks follow-up

  • Metric properties of Orthognathic Quality of Life Questionnaire (OQLQ): Validity

    Validity refers to the degree to which the instrument measures what it purports to measure. Construct validity was evaluated analyzing the hypothesized relationships between scores by calculating the Spearman correlation coefficients. The orthognathic quality of life questionnaire is a condition specific instrument for assessment oral health quality of life in dentofacial deformities patients 22 ítems values: min = 0 / max = 88 higher scores mean a worse outcome

    baseline

  • Metric properties of Orthognathic Quality of Life Questionnaire (OQLQ): Responsiveness to change

    Responsiveness refers to an instrument's ability to detect change. To evaluate responsiveness of the orthognathic quality of life questionnaire (OQLQ) we applied twice: first one week before surgery (T1), and then three months after surgery (T2) To evaluate responsiveness, a paired t-test was used to assess the score changes in patients undergoing orthognathic surgery. The magnitude of the change was evaluated calculating the standardized response mean. The orthognathic quality of life questionnaire is a condition specific instrument for assessment oral health quality of life in dentofacial deformities patients 22 ítems values: min = 0 / max = 88 higher scores mean a worse outcome

    baseline - 3 months follow-up

  • changes in oral health related quality of life after orthognathic surgery assessed with Orthognathic Quality of Life Questionnaire (OQLQ)

    Orthognathic quality of life questionnaire (OQLQ) was applied at 3 times: baseline, one week before surgery (T1), three months after surgery (T2) and 6 months after surgery (T3). A paired t-test was used to assess the mean (SD) changes in patients undergoing orthognathic surgery. The magnitude of the change was evaluated calculating the standardized response mean (SRM). The orthognathic quality of life questionnaire is a condition specific instrument for assessment oral health quality of life in dentofacial deformities patients 22 ítems values: min = 0 / max = 88 higher scores mean a worse outcome

    baseline to 3 and 6 months follow-up

  • changes in oral health related quality of life after orthognathic surgery assessed with Short form Oral Health Impact Profile (OHIP-14)

    Short form Oral Health Impact Profile (OHIP-14) was applied at 3 times: baseline, one week before surgery (T1), three months after surgery (T2) and 6 months after surgery (T3). A paired t-test was used to assess the mean (SD) changes in patients undergoing orthognathic surgery. The magnitude of the change was evaluated calculating the standardized response mean (SRM). The Short Form Oral Health Impact Profile (OHIP-14) is an instrument for assessment oral health-related quality of life. 14 ítems values: min = 0 / max = 56 higher scores mean a worse outcome

    baseline to 3 and 6 months follow-up

  • changes in health related quality of life after orthognathic surgery assessed with Short Form Health Survey (SF-36)

    The Short Form Health Survey (SF-36) was applied at 3 times: baseline, one week before surgery (T1), three months after surgery (T2) and 6 months after surgery (T3). A paired t-test was used to assess the mean (SD) changes in patients undergoing orthognathic surgery. The magnitude of the change was evaluated calculating the standardized response mean (SRM). The Short Form Health Survey (SF-36) is a generic health-related quality of life questionnaire 36 ítems in addition, each item is scored on a 0 to 100 range so that the lowest and highest possible scores are 0 and 100, respectively. Scores represent the percentage of total possible score achieved. higher scores mean a better outcome

    baseline to 3 and 6 months follow-up
