Abstract

While measures of health-related quality of life (HRQOL) are increasingly being used as outcomes in clinical trials, it is unknown whether HRQOL assessments are influenced by the method of administration. We compared telephone, face-to-face, and self-administration of a commonly-used HRQOL measure, the SF-36. Veterans (N = 172) receiving care in the General Medicine Clinic were randomized into groups differing only in order of administration. All patients were asked to complete the SF-36 three times over a 4-week period. The SF-36 demonstrated high internal consistency, regardless of mode of administration, but showed large variation over short intervals. This variation may: (1) increase dramatically sample size requirements to detect between-group differences in randomized trials and (2) reduce the SF-36's usefulness for clinicians wishing to follow individual patients over time.

Oral Health Impact Profile (OHIP)-14 telephone interview reliability to assess oral health-related quality of life (OHRQoL) in orthosurgical patients
2023, Journal of the World Federation of Orthodontists
The influence of the Oral Health Impact Profile (OHIP)-14 administration method through telephone or face-to-face interviews in orthosurgical patients is unknown. The study aims to assess the reliability of the OHIP-14 questionnaire through its stability and internal consistency when applied through a telephone interview compared with a face-to-face interview.
A total of 21 orthosurgical patients were selected to compare the scores obtained in OHIP-14. The interview was carried out by telephone, and 2 weeks later, the patient was invited to attend a face-to-face interview. Stability was verified by Cohen's kappa coefficient with quadratic weighting for individual items and intraclass correlation coefficient for the total OHIP-14 score. Internal consistency was assessed by Cronbach's alpha coefficient for the total scale and its seven subscales.
Items 5 and 6 showed reasonable agreement in the two modes of administration; 4 and 14 moderate; 1, 3, 7, 9, 11, and 13 substantial; and items 2, 8, 10, and 12 showed almost perfect agreement, according to the Cohen's kappa coefficient test. The instrument's internal consistency was better in the face-to-face interview (0.89) than it was in the telephone interview (0.85). For the evaluation of the seven OHIP-14 subscales, differences were found in functional limitations, psychological discomfort, and social disadvantage subscales.
Although there were some differences in OHIP-14 subscales between the interview methods, the total score of the questionnaire showed good stability and internal consistency. The telephone method can be a reliable alternative for the application of the OHIP-14 questionnaire in orthosurgical patients.
Development and evaluation of the clinimetric properties of the Medication-Related Osteonecrosis of the Jaw Quality of Life Questionnaire (MRONJ-QoL)
2022, International Journal of Oral and Maxillofacial Surgery
The purpose of this study was to develop a self-administered questionnaire (MRONJ-QoL) to assess the quality of life (QoL) of patients with medication-related osteonecrosis of the jaw (MRONJ). A prospective study was performed to develop and evaluate the questionnaire. The MRONJ-QoL was formulated through a review of the literature and interviews of experts and patients. Following development, it was administered to 60 patients with a diagnosis of MRONJ. The sensibility of the questionnaire was assessed by evaluating feasibility (via interviews of patients), face validity (via interviews of patients and experts), and content validity (via evaluation of internal consistency, floor/ceiling effects, and factor analysis). Reliability was evaluated by measuring intra-rater reliability. Construct validity of the questionnaire was evaluated by both cross-sectional and longitudinal comparisons, including comparing scores of the MRONJ-QoL to disease resolution at 6 months. The final MRONJ-QoL questionnaire consisted of 14 questions, demonstrating high internal consistency (Cronbach’s alpha of 0.85) and good reliability (weighted kappa score of 0.65). At the 6-month follow-up, disease resolution was found to be significantly associated with improved MRONJ-QoL scores, suggesting validity of the questionnaire (P < 0.01). Therefore, this is a sensible, reliable, and valid questionnaire for evaluating the QoL of patients with MRONJ.
Rhinoplasty: French validation of the MiRa scale
2020, Annales Francaises d'Oto-Rhino-Laryngologie et de Pathologie Cervico-Faciale
Le but de cette étude était de traduire l’échelle MiRa en français et de valider son utilisation par les chirurgiens francophones.
L’échelle MiRa est une échelle d’analyse validée des dysmorphoses nasales. Peu d’outils d’évaluation esthétique sont disponibles en français. Les recommandations de l’ISPOR et de l’OMS ont été utilisées pour mener à bien le processus de traduction de l’anglais vers le français de cette échelle, en cinq étapes. Pour évaluer la fiabilité de l’échelle MiRa dans sa version française, nous avons comparé statistiquement la répétabilité intra-observateur (comparaison des scores obtenus lorsqu’un observateur évaluait chaque patient deux fois à un mois d’intervalle) et la répétabilité inter-observateur (comparaison des scores obtenus lorsque deux observateurs ont évalué le même patient) en utilisant le test de Wilcoxon et le coefficient de corrélation intraclasse (ICC) (α = 5 %).
Notre objectif était d’obtenir une traduction du concept plutôt qu’une traduction littérale pour permettre une bonne reproductibilité intra- et inter-observateurs.
Chaque étape nous permettait de faire des changements progressifs vers une traduction conceptuelle équivalente à la version originale.
L’échelle MiRa est la seule échelle d’analyse esthétique validée dans la littérature pour les dysmorphoses nasales. L’utilisation combinée de deux recommandations internationales de traduction a permis d’obtenir une version française parfaitement conforme à l’original. Cette version est utilisable par les francophones.
Rhinoplasty: French validation of the MiRa scale
2020, European Annals of Otorhinolaryngology, Head and Neck Diseases
Citation Excerpt :
The MiRa scale has been rigorously developed to validate its reliability [1]. Our translation seeks to be more conceptual than strictly literal [5–10]. The purpose of this study was to translate the MiRa scale into French and validate its use for speakers of French.
The aim of this study was to translate the MiRa scale into French and validate its use for French-speaking surgeons.
ISPOR and WHO recommendations were used to carry out the translation process from English to French in five steps. The MiRa scale is a validated analysis scale of nasal dysmorphoses. Few tools are available in French for French-speaking surgeons. ISPOR and WHO recommendations were used to complete the five-step translation process from English into French. To assess the reliability of the MiRa scale–French version, we statistically compared intra-observer repeatability (comparison of scores obtained when one observer assessed each patient twice at a one-month interval) and inter-observer repeatability (comparison of scores obtained when 2 observers assessed the same patient) using the Wilcoxon test and the intraclass correlation coefficient (ICC) (α = 5%).
Our goal was to obtain a translation of the idea or concept rather than a literal translation to enable good intra- and inter-observer repeatability.
Each step allowed us to make changes gradually working towards a conceptual translation equivalent to the original version.
The MiRa scale is the only aesthetic analysis scale validated in the literature for nasal dysmorphoses. The combined use of two sets of translation recommendations, with a five-step translation-back-translation process, made it possible to obtain a French version perfectly in line with the original. This version is usable by French-speakers.
Measurement and Modeling of Health-Related Quality of Life
2016, International Encyclopedia of Public Health
Health-related quality of life (HRQOL) concerns how well people are able to function and how they feel about physical, mental, and social dimensions of their lives. HRQOL data are most often collected using self-report methods of assessment (e.g., questionnaires or interviews). There are generic and targeted profile measures that yield multiple HRQOL scores as well as preference-based measures that summarize HRQOL in a single score. There are several attributes of good HRQOL measures that include a conceptual model, reliability, validity, interpretation of scores, respondent and administrative burden, alternative assessment modalities, and availability of translations. HRQOL measures are used in research, population surveillance, and clinical practice.
