Translation and validation of EORTC QLQ-H&N 35 into Moroccan Arabic for ENT head and neck cancer patients in Morocco

Cross-cultural adaptation and psychometric properties of patient-reported outcome measures in Arabic speaking countries: A scoping review

BACKGROUND

Patient-reported outcome measures (PROMs) are increasingly recognized as an indicator of healthcare quality and safety. Over the past decades, there has been a growing interest in using PROMs in Arabic-speaking populations. However, there is a paucity of data regarding the quality of their cross-cultural adaptation (CCA) and measurement properties.

OBJECTIVES

To identify PROMs that have been developed, validated or cross-culturally adapted to Arabic and evaluate methodological qualities of CCA and measurement properties.

METHODS

MEDLINE, EMBASE, CINAHL, PsycINFO, IPA, and ISI Web of Science were searched using search terms 'PROMs', 'Arabic countries', 'CCA', and 'psychometric properties'. Measurement properties were evaluated using COSMIN quality criteria and CCA quality was assessed using the Oliveria rating method.

RESULTS

This review included 260 studies with 317 PROMs, focusing on psychometric testing (83.8%), CCA (75.8%), utilizing PROMs as outcome measures (13.4%), and developing PROMs (2.3%). Out of the 201 cross-culturally adapted PROMs, forward translation was the most frequently reported component of CCA (n = 178), followed by back translation (n = 174). Out of the 235 PROMs that reported measurement properties, internal consistency was the most frequently reported measurement property (n = 214), followed by reliability (n = 160) and hypotheses testing (n = 143). Other measurement properties were less reported, including responsiveness (n = 36), criterion validity (n = 22), measurement error (n = 12), and cross-cultural validity (n = 10). The strongest measurement property was hypotheses testing (n = 143), followed by reliability (n = 132).

CONCLUSION

There are several caveats regarding the quality of CCA and measurement properties of PROMs included in this review. Only 1 out of 317 Arabic PROMs met CCA and psychometric optimal quality criteria. Therefore, there is a need to improve the methodological quality of CCA and measurement properties of PROMs. This review provides valuable information for researchers and clinicians when choosing PROMs for practice and research. There were only 5 treatment-specific PROMs, indicating the necessity for more research focusing on development and CCA of such measures.

Validation of European Organization for Research and Treatment of Cancer Head and Neck Cancer Quality of Life Questionnaire (EORTC QLQ-H&N35) Across Languages: A Systematic Review

The purpose of this review was to identify cross-cultural and psychometric characteristics of the European Organization for Research and Treatment of Cancer Head and neck cancer questionnaire (EORTC QLQ-H&N35) in various languages. A literature search was performed for original papers in PubMed, EMBASE, and Google scholar electronic databases on validation, psychometric properties of the EORTC-H&N35 questionnaire for patients with head and neck cancer. A total of 17 papers had been reviewed systematically. The studies were conducted in 28 countries and EORTC QLQ-H&N35 questionnaire was validated in 21 different languages. The majority of papers reported high reliability having Cronbach's coefficient above 0.70. Low reliability was reported for senses and speech problems, pain, and less sexuality. Moderate to good convergent validity was found as the correlation coefficient was above 0.40 except for speech problems and social contact trouble. Discriminant validity (weak correlations < 0.70) was confirmed in 14 papers. This review provides comprehensive information on cross-cultural and psychometric properties of EORTC QLQ-H&N35 and can be recommended to implement in oncological practice.

Psychometric properties of the Urdu version of the EORTC QLQ-H&N35 (European organization for research and treatment of cancer head and neck module) quality of life tool

Background

We translated and validated the Urdu version of the European Organization for Research and Treatment of Cancer Quality of Life (QoL) Questionnaire’s Head and Neck (H&N) Cancer Module (EORTC QLQ-H&N35) and assessed its convergent and discriminant validity by examining correlations of QoL with depression, anxiety, and resilience.

Methods

We translated the EORTC QLQ-H&N35 according to EORTC instructions. Patients at a tertiary care hospital in Pakistan completed a survey consisting of Urdu versions of EORTC QLQ-C30 (core QoL tool), QLQ-H&N35, Hospital Anxiety and Depression Scale, and Wagnild and Young Resilience Scale (RS-14). Content validity, convergent validity, discriminant validity, and reliability (using Cronbach’s alpha) of the EORTC QLQ-H&N35 were assessed.

Results

Our sample comprised 250 patients with H&N cancer, most commonly oral (82%). The Urdu translations were comprehensible for all patients. The Cronbach alpha for QLQ-H&N35 multi-item domains ranged from 0.75 to 0.98 (acceptable to excellent), barring “Senses Problems”, which was less than the generally acceptable level (0.50). The patient-reported content validity index (CVI) scores for relevance and clarity of the Urdu version of the QLQ-H&N35 were 0.93 and 0.92, respectively (both excellent). Our results revealed weak bidirectional correlations of the QLQ-H&N35 with resilience, depression, and anxiety, showing good discriminant validity. A weak-to-moderate but significant negative correlation (r: − 0.185 to − 0.613; p < 0.01) was seen between the QLQ-H&N35 and the global QoL measure of the QLQ-30.

Conclusion

Our Urdu translation of the EORTC QLQ-H&N35 demonstrated validity comparable to previous studies, with good discriminant construct validity when measured against resilience, depression, and anxiety. An issue of concern is the poor internal consistency of the “Senses Problems” domain. Nevertheless, the Urdu translation produced in this study serves as a valid and reliable measure to measure QoL in H&N cancer in clinical or research settings in Pakistan.

Quality of Life of Patients After Treatment for Cancer in the Head and Neck Region: A Case-Control Study

Introduction: It is known that side effects caused by antineoplastic therapy can affect patients' quality of life (QOL). However, the long-term effects on patients’ quality of life are not well known. This study aimed to evaluate patients' quality of life who underwent radiotherapy for head and neck cancer lasting more than six months compared to individuals who did not experience treatment.

Methods: Thirty-three patients who underwent treatment for cancer in the head and neck region for at least six months and sixty-six individuals without cancer matched for age and sex were given the European Organization for Research and Treatment of Cancer QLQ-C30/QLQ-H & N35 questionnaires. Other pertinent information from patients was taken from the hospital chart. The Mann-Whitney nonparametric test was applied to verify the statistical significance of the difference in means between the groups, and a significance of 5% was considered.

Results: Group 1 consisted of 33 patients with a mean age of 63.42 ± 11.25 years; 81.8% were smokers; 84.8% were drinkers; the sites most affected by cancer were the palate/oropharynx and the floor of the mouth (7 cases), and the most common type was epidermoid carcinoma (78.79%). The overall quality of life was 61.62. Among group 2 patients, the average age was 64.27; 84.85% were smokers, and 65.15% were drinkers. The overall quality of life was 71.46 in group 2. There was a group of variables in which the scores of patients without cancer were statistically lower (better quality of life) than those presented by cancer patients, namely, loss of appetite, pain, swallowing, cognitive problems, speech problems, problems eating in public, sexuality, teeth, mouth opening, dry mouth, sticky saliva, nutritional supplements, feeding tube, and weight gain.

Conclusion: Patients who underwent antineoplastic treatment for more than six months had a worse overall quality of life than individuals who did not experience such treatment. These patients had worse results in the components of appetite loss, pain, swallowing, cognitive problems, speech problems, problems with public eating, sexuality, teeth, mouth opening, dry mouth, sticky saliva, nutritional supplement, feeding tube, and weight gain.

Validity and Reliability of an Arabic Version of MD Anderson Dysphagia Inventory (MDADI)

Dysphagia is a common adverse event among head and neck (H&N) cancer patients. We aimed, for the first time, to validate the Arabic version of the MD Anderson Dysphagia Inventory (MDADI) among 82 Saudi Arabian patients with H&N cancer. We followed established validation guidelines and translated the 20-item MDADI using the forward-backward method. Our results revealed 100% feasibility. Test-retest reliability demonstrated acceptable interclass correlation coefficients (ICC) for the subscale domains (emotional = 0.973, physical = 0.971, and functional = 0.956) and composite score (ICC = 0.984). The Cronbach's alpha coefficients for the emotional, functional, and physical subscales were 0.937, 0.825, and 0.945, respectively (composite score = 0.975). We confirmed concurrent validity by demonstrating significant correlations between the domains of the Arabic MDADI and European Organization for Research and Treatment of Cancer (EORTC) Quality-of-Life Head and Neck Module (QLQ-H&N35). Our study validated the Arabic version of the MDADI among H&N cancer patients from Saudi Arabia.

Psychometric evaluation of Azeri version of the head and neck cancer specific quality of life questionnaire (EORTC QLQ-H&N43)

BACKGROUND

Oral cancer surgery can have a deep effect on the quality of life in the patient both in terms of functional and psychological aspects. This study aimed to translate and validate the European Organization for Research and Treatment of Cancer head and neck cancer specific quality of life questionnaire (EORTC QLQ-H&N43) in Azerbaijan.

METHODS

Forward-backward translation was applied in order to translate the EORTC QLQ-H&N43 from English into Azeri. Then, a sample of patients with oral cancer attending a teaching hospital affiliated to Azerbaijan Medical University completed the EORTC QLQ-C30 (the core cancer specific questionnaire), and the EORTC QLQ-H&N43. To evaluate psychometric properties of the QLQ-H&N43, known groups validity, convergent and divergent validity was performed. Internal consistency reliability was examined by estimating the Crornbach's alpha coefficient.

RESULTS

Ninety-six patients with confirmed diagnosis of oral cancer were entered into the study. The mean age of patients was 59.6 (SD = 10.7) years and 36 patients (37.5%) diagnosed as having stage IV and 10 patients (10.5%) were metastatic. The results obtained from comparing quality of life scores among these patients showed that the questionnaire was able to differentiate among patients who differed in stage and metastasis lending support to its validity. In addition convergent and divergent validity showed satisfactory results. The internal consistency of the multi-item scales as assessed by the Cronbach's alpha coefficient showed acceptable results (alpha ranging from 0.66 to 0.78).

CONCLUSION

The findings suggest that in general the Azeri version of EORTC QLQ-H&N43 has satisfactory internal consistency reliability and validity, but additional psychometric evaluation is needed to draw firm conclusions.

Patient-reported outcomes for dental health, shoulder-neck dysfunction, and overall quality of life after treatment with radiation for head and neck cancer

OBJECTIVES

The current exploratory cross-sectional study was designed to examine and characterize survivorship issues among patients treated with radiation for head and neck cancer with regard to dental health, shoulder-neck dysfunction, and overall quality of life (QOL).

METHODS

Patients (N = 58) being seen for follow-up at a radiation oncology clinic at least 1 year beyond the end of treatment completed three survey questionnaires regarding general QOL as well as dental health issues and shoulder-neck dysfunction. The questionnaires were scored and univariate analyses were performed using the variables of age, radiation dosage, definitive radiation + neck dissection versus definitive surgery + postoperative radiation, and chemotherapy.

RESULTS

Median follow-up was 2.5 years. Of 58 patients, 35% reported having more problems with their general dental health as compared to before treatment and 38% reported having pain at night in the neck/shoulder after treatment. With regard to pretreatment counseling, 79% of patients reported being counseled about their dental health prior to treatment, while 31% reported being counseled about possible shoulder-neck dysfunction. Patients younger than 65, patients receiving higher doses of radiation, and patients undergoing definitive surgery + postoperative radiation reported more functional and symptomatic issues.

CONCLUSION

Patients treated with radiation for head and neck cancer face a number of survivorship issues, including problems with dental health and shoulder-neck dysfunction, and are not necessarily thoroughly counseled about these issues prior to treatment. Patients younger than 65, patients receiving higher doses of radiation, and patients undergoing definitive surgery + postoperative radiation may experience more survivorship issues.

A systematic literature review of health state utility values in head and neck cancer

BACKGROUND

Health state utility values (HSUVs) are essential parameters in model-based economic evaluations. This study systematically identifies HSUVs in head and neck cancer and provides guidance for selecting them from a growing body of health-related quality of life studies.

METHODS

We systematically reviewed the published literature by searching PubMed, EMBASE and The Cochrane Library using a pre-defined combination of keywords. The Tufts Cost-Effectiveness Analysis Registry and the School of Health and Related Research Health Utilities Database (ScHARRHUD) specifically containing health utilities were also queried, in addition to the Health Economics Research Centre database of mapping studies. Studies were considered for inclusion if reporting original HSUVs assessed using established techniques. The characteristics of each study including country, design, sample size, cancer subsite addressed and demographics of responders were summarized narratively using a data extraction form. Quality scoring and critical appraisal of the included studies were performed based on published recommendations.

RESULTS

Of a total 1048 records identified by the search, 28 studies qualified for data extraction and 346 unique HSUVs were retrieved from them. HSUVs were estimated using direct methods (e.g. standard gamble; n = 10 studies), multi-attribute utility instruments (MAUIs; n = 13) and mapping techniques (n = 3); two studies adopted both direct and indirect approaches. Within the MAUIs, the EuroQol 5-dimension questionnaire (EQ-5D) was the most frequently used (n = 11), followed by the Health Utility Index Mark 3 (HUI3; n = 2), the 15D (n = 2) and the Short Form-Six Dimension (SF-6D; n = 1). Different methods and types of responders (i.e. patients, healthy subjects, clinical experts) influenced the magnitude of HSUVs for comparable health states. Only one mapping study developed an original algorithm using head and neck cancer data. The identified studies were considered of intermediate quality.

DISCUSSION

This review provides a dataset of HSUVs systematically retrieved from published studies in head and neck cancer. There is currently a lack of research for some disease phases including recurrent and metastatic cancer, and treatment-related complications. In selecting HSUVs for cost-effectiveness modeling purposes, preference should be given to EQ-5D utility values; however, mapping to EQ-5D is a potentially valuable technique that should be further developed in this cancer population.
