Validation of the Spanish version of the Goodman score in total hip arthroplasty

Abstract

Purpose Currently, patient-reported outcome measures (PROMs) are the standard instruments used to compare arthroplasty results. Goodman et al. recently published a well-constructed scale with excellent psychometric properties that can be quickly administered. The main objective of our study was to translate, culturally adapt, and validate a Spanish version of the Goodman questionnaire in patients who underwent total hip arthroplasty (THA). Methods The original Goodman scale was translated into Spanish and cross-culturally adapted. Then, the data from this version were tested for psychometric quality. We designed a cross-sectional study for data collection. This study enrolled 2 institutions. Patients who underwent hip replacement due to primary osteoarthritis secondary to dysplasia between 1 January 2018 and 31 December 2019 were included. A total of 153 patients were contacted twice to record the Goodman and Oxford hip scales (OHS) to assess the validity of the questionnaire. Reliability was tested using the Cronbach’s alpha, Concordance using 3 test: intraclass correlation coefficient (ICC), Lin's concordance correlation coefficient (CCC), and the Bradley-Blackwood F test. The spearman correlation was used to asses correlation between the OHS and the Spanish-adapted Goodman scale. Results The overall satisfaction after THA was reported to be “very satisfied” by 137 patients (75%), and only 14 patients reported some degree of dissatisfaction (6%). The improvement in quality of life was reported to be “more than I ever dreamed possible” by 41% patients. Cronbach’s alpha was acceptable, reaching a coefficient of 0.95 (95% confidence interval, 0.82–1). No statistical difference (t test, p = 0.55) was found in the original version, with great internal validity. Test re-test concordance was optimal among the 3 tests used. A moderate correlation was found between the OHS and the Spanish-adapted Goodman scale. Conclusion The Spanish version of the Goodman questionnaire in THA is a reliable, consistent, and feasible scale to evaluate patient satisfaction and improvement in the quality of life in Spanish speakers.

Similar Patient Satisfaction and Quality of Life Improvement Achieved with TKA and THA According to the Goodman Scale: A Comparative Study

“…The original Goodman study reported a significant moderate correlation with both HOOS and KOSS [6]. In its Spanish validation, a similar correlation was noted with the OHS [7]. Moreover, in knee patients, the KUJALA, KOOS quality of life, and WOMAC scales can predict the Goodman score, yielding an area under the ROC curve of 0.82 (95% CI: 0.70 to 0.94) [9].…”

Anterior knee pain and sit-up tests predicts patients’ satisfaction and improvement in quality of life after anterior stabilized total knee replacement without patellar resurfacing

“…The recent development of better instruments to assess satisfaction has enabled researchers to compare more reliable results and establish what satisfaction means for patients [27]. The Goodman scale is reliable and aims to determine satisfaction and patients' self-perceived improvement after TKA [7,18,56].…”

“…Additionally, all patients were asked if they experienced anterior knee pain. The principal outcome of the study was satisfaction and patients' perceived improvement in their quality of life after TKA, using the Goodman scale, which has been validated for TKA and adapted for Spanish speakers [7,18,56]. This scale has two sections.…”

“…Patient satisfaction and improvement in quality of life are the primary outcomes to be achieved after TKA. Recently, Goodman et al developed a reliable scale to objectively measure both outcomes, which has been validated and adapted for Spanish speakers [7,18]. Historically, dissatisfaction rates were set at 20% [31,55].…”

Italian Translation, Adaptation, and Validation of the Novel Satisfaction Measure Assessment after Primary Total Joint Arthroplasty: The Goodman Score Questionnaire

“…Recently, a Spanish adaptation and validation of the Goodman score questionnaire were published, reporting higher Cronbach's alpha (0.95) and test-retest ICC (0.87) than those of both the Italian and English versions [36]. Besides cultural and language differences, the higher indices of the Spanish adaptation may be due to the inclusion in the study of patients undergoing THA only, as well as the use of a larger cohort than the one described in the present study.…”
