Enabling cross-cultural data pooling in trials: linguistic validation of head and neck cancer measures for Indian patients

Understanding data visualization techniques in qualitative studies used to develop and validate patient-reported outcome measures: a targeted literature review

PURPOSE

Qualitative data that reflects patients' experiences are the foundation of any patient-reported outcome measure (PROM) development and validation study; however, there is limited understanding of the type of data visualization techniques that facilitate communication of this data. The goal of this targeted literature review was to investigate data visualization methods that have been used in published PROM development and validation literature to report qualitative results.

METHODS

A literature search in OVID via MEDLINE was conducted among the top 10 non-disease-specific journals publishing PROM qualitative development and validation studies. Studies that reported qualitative methods to develop/validate a PROM and included data visualization in the form of tables or figures were included. Article characteristics and data visualization types were extracted.

RESULTS

A total of 185 articles were included in data extraction. Most articles (n = 109, 59.1%) included figures (n = 172, average 2 relevant figures per article) in the form of hierarchy/flowcharts (n = 124, 72.1%) and bar charts (n = 29, 16.9%). Information reported in figures included depiction of conceptual frameworks (n = 112, 65.1%) and concept frequency (n = 40, 24.4%). Most articles (n = 152, 81.7%) included tables (n = 307, average 2 relevant tables per article). Information reported in tables included concept frequency (n = 133, 43.3%) and cognitive debriefing and revisions (n = 91, 29.6%).

CONCLUSION

Data visualization techniques used to report qualitative results in the identified PROM qualitative development and validation studies were heterogeneous, and many studies did not utilize any data visualization techniques. This study will inform the development of guidance for using data visualizations to report qualitative PROM research.

Translation and Linguistic Validation of BIS (Body Image Scale) for Breast Cancer Patients in India

A number of PROMs (patient-reported outcome measures) have been developed and validated for English-speaking populations but with limited utility in non-English-speaking countries. Body image scale (BIS) is a type of PROM which assesses the changes in the body image of a patient diagnosed with cancer. The current study was carried out to translate the BIS in Hindi and Marathi. Out of the 10 questions in the BIS questionnaire, Hindi and Marathi translations were already available for 4 questions (Questions no. 2, 4, 5, and 9) from the EORTC BR23 questionnaire. Remaining questions were translated using the EORTC translation manual, which includes forward translation, reconciliation, backward translation, proofreading, and pilot testing. Pilot testing done on 10 patients each for Hindi and Marathi showed at least 80% acceptability for all the questions for both Hindi and Marathi translations. Both the translated versions will be used for validation in a large cohort of breast cancer patients. The Hindi and Marathi versions of the BIS have very good acceptability and can be utilized for clinical trials once validated in cancer patients.

Development and implementation barriers of a new patient-reported measure: The Radiation therapy-related Inconvenience Questionnaire (RIQ)

INTRODUCTION

Radiation therapy (RT) can benefit approximately 50% of cancer patients and contribute to 40% of all cancer cures, yet its utilisation in cancer is low globally. Several factors contribute to this including perceived inconvenience related to accessing and utilising RT. To quantitatively assess the latter, a new tool - the Radiation therapy-related Inconvenience Questionnaire (RIQ) - was developed. This study aimed to pre-test the RIQ and explore barriers and facilitators to implementing it in routine clinical practice and clinical trials.

METHODS

Semi-structured cognitive interviews were conducted with patients undertaking RT, recruited via three hospitals to examine content validity, acceptability, and comprehensibility of the RIQ. Interviews identified inconsistencies, relevance, and clarity of items. Semi-structured interviews with healthcare professionals involved in the delivery of care to individuals undertaking RT explored barriers and facilitators to routine usage. Thematic analysis was used to identify themes.

RESULTS

Patients (N = 15) identified problems in content, instructions, layout, length, and response options; consequently, 25 items were revised and eight removed, resulting in a final 29-item questionnaire. Clinicians identified staff- and patient-specific barriers to implementing RIQ in clinical practice. Perceived facilitators included the following: (a) workplace factors, (b) mode of administration, and (c) imparting knowledge.

CONCLUSION

This study demonstrated acceptability and comprehensibility of the 29-item RIQ amongst cancer patients undertaking RT and treating clinicians. The next phase will evaluate the RIQ's measurement properties in a larger clinical study. The barriers and facilitators identified can guide future implementation of RIQ in clinical practice and clinical trials.

Cultural Adaptation of Patient Health Questionnaire-9 in Hindi for Use with Patients with Cancer in Community Palliative Care Settings

Objectives

Patient Health Questionnaire-9 (PHQ-9) in Indian settings is yet not very often used in palliative care with the Hindi-speaking population. The Hindi version of PHQ-9 is available but its cultural adaptation to the Hindi-speaking population in North India receiving palliative care services is required to be tested. PHQ-9 as a depression screening questionnaire may help to identify depression symptoms among patients with cancer. This study aimed to examine the cultural equivalence of PHQ-9 Hindi for use with patients with cancer receiving palliative care services in North India.

Material and Methods

Based on the standard methodology of translation and adaptation of the scale, the following process was used: (i) Two focused group discussions with 17 experts working in a cancer palliative care setting, (ii) qualitative interviewing with 11 patients, and (iii) research team review. All interviews were audio recorded, transcribed, and item-wise content analysis was conducted.

Results

A few difficult phrases in the original PHQ-9 were 'dilchaspi', 'avasadgrast', 'kam urja', 'nakaam', parivar ko neecha dhikhana and 'ashthir' which were changed to Kam Mann Lagna, Mann Dukhi hona, kamjori, saksham nahi hain' 'asafal', Parivar ko nirash karna' and 'bechain,' respectively. Two items, namely no. 6 and 8 were changed to shorten the length for appropriately conveying the meaning.

Conclusion

Hindi language involves various dialects which change from region to region bringing variations in understanding the meaning of the words. It is recommended that culturally equivalent scales are used in practice and research. PHQ-9 is now culturally adapted for the Hindi-speaking population in North India. PHQ-9 will help identidy depressive symptoms at an early stage. Psychometric testing of PHQ-9 is underway.

The Patient Concerns Inventory in head and neck oncology: a structured review of its development, validation and clinical implications

Introduction

The Patient Concerns Inventory (PCI) is a condition specific prompt list that was initially developed for head and neck cancer (HNC) and is referred to as the PCI–HN. There have been numerous publications regarding the PCI–HN, since it was first published in 2009. To date, there has not been a review of its development, validation and clinical implications. A collation of relevant papers into key sections allows multidisciplinary teams and researchers to have an overview of the PCI–HN’s background, evaluation and utility. This is essential if colleagues are to have confidence in the tool and be able to reflect on how to optimise its use in clinical practice.

Methods

Five search engines were used: EMBASE, Medline, PubMed, CINAHL and Handle-on-QOL for the specific term ‘Patient Concerns Inventory’ up to and including 1st February 2022. In addition, an accumulation of PCI–HN data of 507 HNC patients was drawn from previous studies in Liverpool and Leeds between 2007 and 2020 and was analysed specifically for this paper.

Results

54 papers relating to the PCI–HN were identified. The review is structured into eight sections: (1) What is the PCI–HN and how does it work; (2) Feasibility and acceptability; (3) Psychometrics; (4) Items selected and frequency (5) Associations with Health-Related Quality of Life (HRQOL) and casemix; (6) Other observational studies; (7) Randomised trial evaluation; (8) General discussion and further research.

Conclusions

As the term PCI is quite ubiquitous and produces many hits when searching the literature, this review provides a very concise and convenient historical context for the PCI–HN and collates the current literature.

Body Image Scale: Evaluation of the Psychometric Properties in Three Indian Head and Neck Cancer Language Groups

Background

Body image is a subjective concept encompassing a person's views and emotions about their body. Head and neck cancer (HNC) diagnosis and treatment affects several psychosocial concepts including body image. Large numbers of HNC patients are diagnosed each year in India but there are no suitable measures in regional languages to assess their body image. This study assessed the psychometric properties of the Body Image Scale (BIS), a measure suitable for clinical and research use in HNC populations, translated into Tamil, Telugu and Hindi and compared body image distress between language groups.

Methods

Translated versions of BIS were completed by HNC patients recruited from three cancer centers across India one time only. Psychometric evaluation was conducted including factor analysis using principal component analysis and internal consistency reliability using Cronbach's alpha. Patients completed the EORTC Quality of Life Questionnaire (QLQ) C-30 and EORTC QLQ HN-35 measures to enable exploration of convergent and discriminant validity. ANOVA was used to calculate difference in mean values for body image.

Results

Our sample included 621 HNC patients (Tamil = 205, Telugu = 216, Hindi = 200). Factor analysis revealed a one-factor solution and Cronbach's alpha coefficients ranged between 0.891 and 0.969 indicating good reliability. Hypothesized correlations between similar and different constructs were as expected, supporting construct validity. On the BIS, we found a statistically significant difference (F = 11.0954, P < 0.05) between means of Tamil, Telugu, and Hindi groups, with higher body image scores in Telugu (M = 12.86; SD = 7.65) and Hindi groups (M = 12.52; SD = 7.36) indicating more symptoms/body image distress, when compared to Tamil population (M = 9.28; SD = 10.04).

Conclusion

The reliability and validity of the three translated Indian versions of the BIS were maintained, providing a method for assessing body image of HNC population worldwide speaking Tamil, Telugu, and Hindi across the illness trajectory.

Patient-reported anxiety and depression measures for use in Indian head and neck cancer populations: a psychometric evaluation

BACKGROUND

Head and neck cancers (HNC) are one of the most traumatic forms of cancer because they affect essential aspects of life such as speech, swallowing, eating and disfigurement. HNCs are common in India, with over 100,000 cases being registered each year. HNC and treatment are both associated with considerable anxiety and depression. With increasing multinational research, no suitable measures in Indian languages are available to assess anxiety and depression in Indian HNC patients. This study evaluated the psychometric properties of cross-culturally adapted versions of Zung's self-rating Anxiety Scale (SAS) and the Patient health questionnaire - 9 (PHQ-9) in Tamil, Telugu and Hindi speaking Indian HNC populations.

METHODS

HNC patients were recruited from three tertiary cancer centres in India. Patients completed the cross-culturally adapted versions of SAS and PHQ-9. We assessed targeting, scaling assumptions, construct validity (exploratory and confirmatory factor analyses), convergent validity, and internal consistency reliability.

RESULTS

The study sample included 205 Tamil, 216 Telugu and 200 Hindi speaking HNC patients. Exploratory and confirmatory factor analyses indicated a two-factor solution for PHQ-9 and four-factor solution for SAS in all three languages. Cronbach's alpha coefficients ranged between 0.717 and 0.890 for PHQ-9 and between 0.803 and 0.868 for SAS, indicating good reliability. Correlations between hypothesized scales were as expected providing evidence towards convergent validity.

CONCLUSIONS

This first psychometric evaluation of the measurement properties of Tamil, Telugu and Hindi versions of the SAS and PHQ-9 in large, Indian HNC populations supported their use as severity and outcome measures across the disease and treatment continuum.
