Development and Validation of a Cancer AwarenessQuestionnaire for Malaysian Undergraduate Students ofChinese Ethnicity

Objectives: To describe the development and validation of a cancer awareness questionnaire (CAQ) based ona literature review of previous studies, focusing on cancer awareness and prevention. Materials and Methods: Atotal of 388 Chinese undergraduate students in a private university in Kuala Lumpur, Malaysia, were recruitedto evaluate the developed self-administered questionnaire. The CAQ consisted of four sections: awareness ofcancer warning signs and screening tests; knowledge of cancer risk factors; barriers in seeking medical advice;and attitudes towards cancer and cancer prevention. The questionnaire was evaluated for construct validityusing principal component analysis and internal consistency using Cronbach’s alpha (α) coefficient. Test-retestreliability was assessed with a 10-14 days interval and measured using Pearson product-moment correlation.Results: The initial 77-item CAQ was reduced to 63 items, with satisfactory construct validity, and a high totalinternal consistency (Cronbach’s α=0.77). A total of 143 students completed the questionnaire for the test-retestreliability obtaining a correlation of 0.72 (p<0.001) overall. Conclusions: The CAQ could provide a reliableand valid measure that can be used to assess cancer awareness among local Chinese undergraduate students.However, further studies among students from different backgrounds (e.g. ethnicity) are required in order tofacilitate the use of the cancer awareness questionnaire among all university students.     

Validation of the Chinese version of EORTC QLQ‐BN20 for patients with brain cancer

This is a single centre study in mainland China aiming to evaluate the reliability, validity and responsiveness of the Chinese version of EORTC QLQ‐BN20, designed by The European Organization for Research and Treatment of Cancer Quality of Life Group to evaluate the life quality of patients with brain tumour, cancer or metastases. One hundred and eighty‐eight patients with primary or secondary brain cancer from Hunan Provincial Tumor Hospital during September 2013 to June 2014 completed the Chinese EORTC QLQ‐C30/BN20 questionnaires developed by translation, back translation and cultural adaptation. Results were statistically analysed using SPSS17.0. The internal consistency (Cronbach's α coefficient) was between .753 and .869, the correlation coefficients among items and its own dimension were bigger than .4, and all items had a better correlation with its own dimension. The Spearman was used to analyse the correlation of each dimension between EORTC QLQ‐BN20 and EORTC QLQ‐C30, and the result showed that individual dimensions were moderately correlated, other dimensions were weakly correlated. In conclusion, the Chinese version of EORTC QLQ BN20 questionnaire had great relevance, reliability, convergent validity and discriminant validity. It provides a valuable tool for the assessment of health‐related quality of life in clinical studies of Chinese patients with primary or secondary brain cancer.     

The validation of a quality of life scale to assess the impact of arm morbidity in breast cancer patients post-operatively

This paper documents the validation of a quality of life scale (QOL) designed to assess the impact of arm morbidity on patients following breast cancer surgery. A four item arm subscale was developed to supplement a multi-dimensional, validated breast cancer QOL tool, the functional assessment of cancer therapy (FACT-B.) The new questionnaire, the FACT-B+4, was validated on 279 women participating in a trial of sentinel node guided axillary therapy and 29 women attending a lymphoedema clinic. The subscale demonstrated good internal consistency (alpha co-efficient=0.62 to 0.88) and stability (test–retest reliability=0.97). Lymphoedema patients reported significantly greater arm problems than a matched sample of pre-operative trial participants. The lymphoedema group also scored lower than trial patients on the FACT-B+4 indicating a poorer quality of life (p<0.05). A subset of 66 trial patients who had completed three consecutive assessments was used to evaluate the sensitivity of the questionnaire to change over time. Scores on the FACT-B+4 were found to decline significantly between the pre-operative assessment and post-operative assessment at 1 month. Arm problems significantly increased during this period. FACT-B+4 score increased again from 1 month to 12 weeks post-surgery and symptoms reduced, as the extent of arm morbidity resolved. The FACT-B+4 appears to be psychometrically robust and sensitive to patient rehabilitation, making it suitable for use in longitudinal surgical trials. Given the dearth of existing scales available to measure arm morbidity, we hope this new tool will prove useful to researchers     

The Azeri Version of European Organization for Research and Treatment of Cancer Core Quality of Life Questionnaire (EORTC QLQ-C30): Translation and Validation

Objective: Quality of life in cancer patients has become an important outcome measure. This study aimed to translate and validate the European Cancer Research and Treatment Core Quality of Life Questionnaire (EORTC QLQ-C30) in Azerbaijan. Methods: Forward-backward procedure was applied to translate the EORTC QLQ-C30 from English into Azeri. Then a cross sectional study was conducted to validate the questionnaire in Azerbaijan. A sample of patients with confirmed diagnosis of oral cancer completed the Azeri version of the questionnaire from January 2017 to December 2018. Construct validity was assessed by performing know groups comparison and item-scale correlation matrix. Reliability was examined by estimating the Cronbach’s alpha coefficient for internal consistency. Results: In all 141 patients with oral cancer participated in the study. Known groups comparison indicated that the Azeri version of EORTC QLQ-C30 well differentiated between patients who differed in the disease stage. Those with higher stage reported lower functioning and higher symptoms. In addition item-scale correlation matrix showed a good correlation between items and its own hypothesized subscales as expected (Pearson correlation coefficient ranging from 0.735-0.978). The Cronbach’s alpha coefficient ranged form 0.68 to 0.94 indicating acceptable results for the internal consistency of the questionnaire. Conclusion: This preliminary validation study proved that the Azeri version of EORTC QLQ-C30 is a valid measure of quality of life in cancer patients. However, studies with other cancer patients and stronger psychometric evaluations are recommended.     

Psychometric Validation of the Eortc Core Quality of Life Questionnaire, 30-Item Version and A Diagnosis-Specific Module for Head and Neck Cancer Patients

A cancer-specific self-reporting quality of life questionnaire has been validated. The questionnaire is designed to assess physical functioning, role functioning, cognitive functioning, emotional functioning, social functioning, pain, fatigue, emesis and quality of life by means of multi-item scales, and other disease- and treatment-related symptoms by means of single items. The questionnaire was completed by 126 head and neck cancer patients with a mean age of 67 years. The internal consistency (scale reliability) was satisfactory for all scales but one. Correlations between scales and items assessing the same underlying dimension were also satisfactory. The questionnaire discriminates between patient subgroups and between acute, subacute and late toxicity. Patient compliance was high. The questionnaire provided valuable information, and most of the scales/items functioned well. A few problems were found, especially with the modified visual analogue scales, and minor modifications will be made.

Quick-FLIC: validation of a short questionnaire for assessing quality of life of cancer patients

A practically useful measure of quality of life should be simple and quick to complete. A shortened Chinese version of the Functional Living Index - Cancer (FLIC) was recently proposed and was called Quick-FLIC. This study aims to assess the measurement properties of the Quick-FLIC. A total of 190 patients who received care from the National Cancer Centre of Singapore completed a questionnaire package at baseline. Patients filled in a retest questionnaire on average 2 weeks after baseline to assess test-retest reliability and responsiveness to change. The Quick-FLIC scores correlated well with the Functional Assessment of Chronic Therapy - General scores (r=0.78). Patients with different treatment status, performance status and self-rated health had significantly different Quick-FLIC scores in the expected directions (ANOVA; each P<0.001). Internal consistency (Cronbach's alpha=0.87) and 2-week test-retest reliability (intraclass correlation=0.81) were also satisfactory. The measure was responsive to changes in health status (P<0.001). The Quick-FLIC is a valid and reliable measure of health-related quality of life of cancer patients. The shortening of established health-related quality of life instruments should be considered in order to reduce the burden of having patients to answer lengthy questionnaires.

Purpose: Despite the increasing prevalence of nonalcoholic fatty liver disease (NAFLD), a liver cancer etiological factor, among Chinese young adults (CYA), there is a lack of valid, reliable, ready-to-use survey instruments for assessing awareness and knowledge of NAFLD in this population. The aims of this study were to develop, validate, and assess the reliability of a web-based, self-administered questionnaire evaluating awareness and knowledge of NAFLD among CYA. Methods: Based on review of relevant literature, a draft questionnaire was initially developed. Face and content validity of the questionnaire was evaluated by an expert panel of seven gastroenterologists. The construct validity was tested through item analysis based on item response theory. Reliability assessment included test-retest for stability and test for internal consistency. Two pilot tests were conducted among 60 randomly selected students at Lanzhou University, China, through WeChat App. Results: The content validity and clarity indexes were both greater than 0.85. Face validity was established by concluding that questions had no issue with feasibility, readability, clarity of wording, clarity of layout, and style. Response rates for two pilot tests were 96.7% (58 out of 60) and 98.3% (59 out of 60), respectively. Results testing the construct validity showed estimated amount of information obtained by the test between -3 and +3 range of ability was 97.57%. The test-retest reliability (Pearson’s r) was 0.62. The internal consistency (KR20) was 0.92. Conclusions: This newly developed questionnaire is a reliable and valid instrument for assessing awareness and knowledge of NAFLD among this sample from CYA.
