Oral-health-related quality of life in patients with cancer: cultural adaptation and the psychometric testing of the Persian version of EORTC QLQ-OH17

Translation and validation of Sinhala version of modified EORTC QLQ-OH15 in oral cancer patients who receive radiotherapy with or without chemotherapy in Sri Lanka

Background

The recognition of patient-reported outcomes for oral cancer is important in improving patients’ quality of life. The aim of this study was to translate and validate the modified Sinhala version of the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Oral Health Module (EORTC QLQ-OH15).

Methods

A cross-sectional study was conducted to validate the EORTC QLQ-OH15 that was modified after adding two questions to the original questionnaire. The two questions added were ‘difficulty in opening the mouth wide’ and ‘trouble with talking’ which affect oral health related quality of life (OHRQOL) of oral cancer patients receiving radiotherapy. The Sinhala translated modified EORTC QLQ-OH15 and already validated the core questionnaire EORTC QLQ-C30 were self-completed by 85 adult oral cancer patients who received initial anti-cancer treatment with radiotherapy with or without chemotherapy. Content and face validity were examined by an expert panel. Construct validity was confirmed by using factor analysis, multi-trait scaling analysis, and known group comparison. Reliability was assessed by internal consistency, test–retest reliability by Wilcoxon Signed Ranks Test and intra class correlation coefficient. Responsiveness to change was assessed.

Results

The majority of participants (58%) were aged 50–69 years and 84% were males. Nearly 32% had cancer of the anterior two thirds of the tongue. Of the sample, 66% received chemo radiotherapy. Thirteen items were included for the factor analysis. They were loaded for four factors. Three scales ‘Eating problem’, ‘Gum and Speech problem’ and ‘Soreness’ loaded with 5, 4 and 3 items respectively and single item ‘teeth’ to a one factor with the total variance explained was 72.74%. Mann–Whitney U tests for all three scales were statistically significant confirming the ability of the modified EORTC QLQ-OH15 to detect expected differences in OHRQOL in clinically different groups. Cronbach’s alpha for all the scales were more than 0.8. Wilcoxon Matched Paired Sign Rank Test showed highly significant results (p < 0.05) for all three scales revealing high responsiveness.

Conclusions

The modified Sinhala version of the EORTC QLQ-OH15 is a valid, reliable tool that can be used to measure OHRQOL in oral cancer patients who receive radiotherapy with or without chemotherapy.

Psychometric Testing of the Chinese Version of Supportive Care Needs Survey for Partners and Caregivers of Cancer Patients

The objective of this study was to test the psychometric properties of the Chinese version of the Supportive Care Needs Survey for Partners and Caregivers (SCNS-P&C-C) among the caregivers of Chinese patients with cancer. The original English version of SCNS-P&C was translated into Chinese using a forward and backward translation approach. The psychometric properties of the SCNS-P&C-C including factor structure, convergent, and discriminative validities and internal consistency were then tested. A convenience sample of 498 caregivers of hospitalized patients with cancer was recruited from oncology units in three tertiary public hospitals in Hefei city, mainland China. Exploratory factor analysis revealed four domains of the SCNS-P&C-C, which resemble the original English version scale. The convergent validity of the SCNS-P&C-C has established with statistically significant correlations between the SCNS-P&C-C and the Chinese version of Kessler Psychological Distress Scale (r = 0.327, P < 0.01). The SCNS-P&C-C has also good internal consistency with Cronbach's alpha coefficients ranging from 0.79 to 0.89 for the four subscales and 0.94 for the total scale. The Chinese version of the SCNS-P&C was found to be reliable and valid to assess the supportive care needs for partners and caregivers of Chinese patients with cancer. The SCNS-P&C-C can be used to assess and understand the supportive care needs of Chinese caregivers of patients with cancer. Such information will help the healthcare professionals to formulate tailored supportive care services for the caregivers of Chinese patients with cancer.

The association of tooth loss, toothbrushing, and quality of life among cancer survivors

BACKGROUND

Tooth loss contributes physically and psychologically to health, and quality of life has been a key indicator of the cancer survivors. However, it is less clear whether tooth loss has impact on cancer survivors' quality of life. Our study aimed to investigate the association between tooth loss, toothbrushing, and quality of life in cancer survivors.

METHODS

A cross-sectional study was conducted among 9125 cancer survivors in Shanghai, China. Sociodemographic characteristics, frequency of tooth brushing, number of tooth loss were collected using a self-reported questionnaire. Quality of life was measured using the EORTC QLQ-C30. Chi-square test was used to compare the distribution of tooth loss and toothbrushing frequency among various cancer sites, sociodemographic factors, socioeconomic status, health conditions. Multiple linear regression models were performed to estimate the effects of tooth loss and toothbrushing on quality of life.

RESULTS

Participants diagnosed with cancer of oral cavity, pharynx, and nasopharynx reported higher percentage of 11+ tooth loss. Cancer survivors with toothbrushing ≥2 times/d reported higher scores in physical, cognitive, and social function and had milder nausea and vomiting, compared with ones with toothbrushing <2 times/d. Tooth loss was associated with milder physical, role and emotional function scores, and severer fatigue, nausea/vomiting, dyspnea, insomnia, appetite loss, constipation, and diarrhea.

CONCLUSIONS

This is the first study to investigate the impact of toothbrushing and tooth loss on quality of life among cancer survivors. Tooth loss was associated with milder physical, role and emotional function scores, and severer fatigue, nausea/vomiting, dyspnea, insomnia, appetite loss, constipation and diarrhea. Toothbrushing had significant positive effect on cancer survivors' quality of life. The present study also provided several public health strategies to improve oral health among cancer survivors.

Reliability and validity of the Chinese version of the Medical Outcomes Study HIV Health Survey (MOS-HIV) in people living with HIV/AIDS (PLWHA) in China

OBJECTIVE

The aim of the study was to assess the psychometric properties of the Medical Outcomes Study HIV Health Survey (MOS-HIV) in people living with HIV/AIDS (PLWHA) in mainland China.

METHODS

A cross-sectional survey was conducted in 646 PLWHA between May 2015 and March 2016 in Dalian, Ningbo, and Zhengzhou City, China. The MOS-HIV includes 35 items and measures 10 scales. These ten scales can be effectively calculated under two summary scale scores, the physical health score (PHS) and the mental health score (MHS), with the physical functioning, pain and role functioning scales contributing to the PHS, the mental health, health distress, quality of life and cognitive function scales contributing to the MHS, and the energy/fatigue, general health and social functioning contributing to both factors. Reliability was measured in terms of internal consistency and test-retest reliability. The internal consistency of the questionnaire was analyzed using Cronbach's α coefficient, and test-retest reliability was assessed using Pearson's correlation coefficient. Validity was analyzed via construct validity, convergent and discriminant validity, and known group validity. Confirmatory factor analyses (CFA) were used to test construct validity. A multiple-group CFA analysis was conducted to investigate whether the MOS-HIV measured the same constructs across gender groups.

RESULTS

The MOS-HIV questionnaire was reliable and valid. Reliability of the PHS and MHS scales was 0.87 and 0.89, respectively. While the Cronbach's α coefficients for each of the dimensions were > 0.70. According to the results of the confirmatory factor analysis (CFA), the hypothesized model was acceptable. The instrument showed factorial invariance across gender groups. All correlation coefficients were greater than 0.40, with a range of 0.60-0.94. The correlation coefficients observed between items and other dimensions were lower than the coefficients for the correlations between items and hypothesized dimensions for all scales, suggesting good convergent and discriminant validity. Patients with CD4 counts >500 cells/mm3 demonstrated better QOL than those with lower CD4 counts on six scales and the PHS (p<0.05) and symptomatic respondents had significantly lower scores than asymptomatic respondents on all the scales except health transition scales (p<0.05) suggesting good known group validity.

CONCLUSIONS

The results of this study provide evidence that the MOS-HIV may be an acceptable, valid and reliable instrument for evaluating QOL of PLWHA in mainland China.

Impact of oral potentially malignant disorders on quality of life

BACKGROUND

Oral potentially malignant disorders (OPMDs) could have a significant psychological impact on patients, principally because of the unknown risk of malignant transformation, while the physical and functional impairments could differ. This study aimed to assess the impact of three different OPMDs and their disease stages on the quality of life (QoL) of affected patients.

METHODS

Oral leukoplakia (OL), oral lichen planus (OLP) and oral submucous fibrosis (OSF) patients who were undergoing treatment at an oral medicine clinic of a dental teaching hospital in India were the study population. All subjects completed the recently developed OPMDQoL questionnaire and a short form 12 item (version 2) health survey questionnaire (SF-12v2). OPMDQoL questionnaire consists of 20 items over four dimensions. A higher score denotes poor OHRQoL. SF-12v2 has two components, a Physical Component Summary (PCS) and Mental Component Summary (MCS).

RESULTS

A total of 150 subjects (50 each of OL, OLP and OSF) participated. OL patients (37.7 ± 7.9) reported significantly better OPMDQoL scores than OLP (47.3 ± 5.8) and OSF (45.4 ± 9.2) patients. OLP patients reported significant problems in obtaining a clear diagnosis for their condition, more so than the other OPMDs. OL patients reported fewer problems for the dimension, "physical impairment and functional limitations" than the OLP and OSF patients. A significant trend was observed with the overall OPMDQoL and MCS, deteriorating as the disease stage increased.

CONCLUSIONS

OLP and OSF have a significant impact on the QoL of affected individuals: OL less so. Increasing stage of the disease is associated with worsening QoL.

Psychometric properties of the Chinese version of the WHOQOL-HIV BREF to assess quality of life among people living with HIV/AIDS: a cross-sectional study

OBJECTIVES

This study aims to assess the psychometric properties of the Chinese version of the WHOQOL-HIV BREF.

DESIGN

Cross-sectional study.

SETTING

Centers for Disease Control and Prevention and infectious disease hospitals in three Chinese provinces.

PARTICIPANTS

Sample of 1100 people living with HIV/AIDS (PLWHA).

INTERVENTIONS

We recruited 1100 PLWHA to evaluate their quality of life (QOL) using the WHOQOL-HIV BREF. Of these participants, 57 were randomly selected to repeat the QOL evaluation 2 weeks later.

MAIN OUTCOME MEASURES

The reliability of the WHOQOL-HIV BREF was assessed in terms of its internal consistency and test-retest reliability. The construct, concurrent, convergent, discriminant and known-group validity were also analysed. In addition, the factorial invariance across genders was assessed.

RESULTS

Cronbach's α coefficient for the overall scale was 0.93. Except for the spirituality domain, which had an α below 0.70 (0.66), the other five domains showed adequate internal consistency. The test-retest reliability revealed a statistically significant intraclass correlation coefficient of 0.72-0.82 (p<0.001). Confirmatory factor analysis found that the six-domain structure produced an acceptable fit to the data. The instrument showed factorial invariance across gender groups. All domains were significantly correlated with the general items and the SF-36 (p<0.01). The correlation coefficients were >0.40 (r=0.40-0.67), except for the association between the spirituality domain and two general items (QOL: r=0.33; health status: r=0.36). Subjects with lower CD4 counts had lower scores for all domains (p<0.05). Symptomatic participants had significantly lower scores than asymptomatic participants on the physical, psychological and independence domains (p<0.05).

CONCLUSIONS

The WHOQOL-HIV BREF revealed good psychometric characteristics among Chinese PLWHA. These findings offer promising support for the use of the WHOQOL-HIV BREF as a measure of QOL among Chinese PLWHA and in cross-cultural comparative studies on QOL.

Psychometric properties of the Chinese version of the Reproductive Concerns After Cancer Scale (RCAC) for young female cancer survivors

PURPOSE

This study aimed to translate, culturally adapt, and test the psychometric properties of the Reproductive Concerns After Cancer scale (RCAC) in young Chinese female cancer survivors.

METHODS

The Chinese version of the RCAC was developed using the standard Functional Assessment of Chronic Illness Therapy (FACIT) translation methodology, and then 800 young Chinese female cancer survivors were recruited to complete the scale. The validation of the RCAC is as follows: (1) content validity was evaluated by a group of experts; (2) factor structure was assessed using confirmatory factor analysis and factorial invariance analysis; (3) convergent validity was determined by correlations with the Patient Health Questionnaire 9 (PHQ-9) and Functional Assessment of Cancer Therapy-General (FACT-G) scale; (4) internal consistency reliability was assessed using Cronbach's α coefficient; and (5) test-retest reliability was assessed using intra-class correlations.

RESULTS

Internal consistency (Cronbach's alpha coefficients ranged from 0.71 to 0.81) and test-retest reliability (intra-class correlation coefficients ranged from 0.82 to 0.95) of the Chinese version of the RCAC were satisfactory. Results also indicated that the content validity index of the RCAC (Chinese version) was good. The Chinese version of the RCAC score was correlated with the PHQ-9 (r = 0.568, p < 0.01) and FACT-G (r = -0.524, p < 0.01) scores, which indicated acceptable convergent validity. Confirmatory factor analysis supported a six-factor structure of the Chinese version of the RCAC with a good model fit. Moreover, multi-group confirmatory factor analysis indicated factorial invariance (configural, metric, scalar, and strict invariance) of the RCAC across cancer types.

CONCLUSIONS

The translation and cross-cultural adaption of the RCAC into Chinese was successful. The Chinese version of the RCAC has suitable factor structure and psychometric properties for reproductive concerns evaluation in young female cancer patients and is appropriate to use in clinical trials of Chinese patients.
