“…Thus, a longitudinal study design could be considered to overcome these limitations. Overall, the psychometric properties of the Greek version were similar to the original English version for the QLQ-MY20 and other language versions for the QLQ-C30 [12, 29, 31, 39–42, 44]. In an attempt by physicians to choose better therapy protocols and adopt better care strategies for patients, these two instruments appear to be suitable for HRQoL measurement in Greek myeloma patients.…”

“…Based on the literature [28, 29], scales measuring similar HRQoL dimensions were hypothesized to be strongly correlated (>0.50 [30]). Construct validity was also examined via the interscale correlations between QLQ-MY20 and QLQ-C30, assuming that conceptually related scales would correlate substantially (>0.40), and that scales with less in common would show lower correlations [9, 31]. Each SF-36 scale was separately regressed against the QLQ-C30 and QLQ-MY20 scales to identify aspects of the disease-specific instruments more closely linked to general HRQoL [32].…”

Objectives. The aim of this study was to assess the psychometric properties of the Greek EORTC QLQ-C30 and QLQ-MY20 instruments. Method. A sample of myeloma patients (N = 89) from two tertiary hospitals were surveyed with the QLQ-C30, QLQ-MY20 and various demographic and disease related questions. The previously validated Greek SF-36 instrument was used as a “gold standard” for health-related quality of life (HRQoL) comparisons. Hypothesized scale structure, internal consistency reliability (Cronbach's alpha) and various forms of construct validity (convergent, discriminative, concurrent and known-groups) were assessed. Results. Multitrait scaling confirmed scale structure of the QLQ-C30 and QLQ-MY20, with good item convergence (96% and 72%) and discrimination (78% and 58%) rates. Cronbach's α was >0.70 for all but one scale (cognitive functioning). Spearman's correlations between similar QLQ-C30 and SF-36 scales ranged between 0.35–0.80 (P < 0.001). Expected interscale correlations and known-groups comparisons supported construct validity. QLQ-MY20 scales showed comparatively lower correlations with QLQ-C30 functional scales, and higher correlations with conceptually related symptom scales. Conclusions. The observed psychometric properties of the two instruments imply suitability for assessing myeloma HRQoL in Greece. Future studies should focus on generalizability of the results, as well as on specific issues such as longitudinal validity and responsiveness.

“…The EORTC QLQ-BR23 is a breast cancer-specific questionnaire including 23-items about the common adverse effects of treatment, outlook for the future, body image, and sexuality (10,11). All of these items were scored on 4-point Likert scales ranging from 1 (not at all) to 4 (very much).…”

IntroductionA number of risk factors have been identified in the pathogenesis of breast tumors. Among these, a great number of factors are attributed to the lifestyle (1). Reduced physical activity during cancer treatment can decrease the capacity for physical conditioning. The late effects of cancer and its treatment may consequently reduce physical activity in survivors. Breast cancer survivors with sedentary lifestyle have a higher risk for early mortality (2).About 20%-70% of breast cancer survivors may have sleep disturbance, which is twice of the general population. Sleep disturbance is more prevalent in women with breast cancer as compared to those with other cancers. They report new or worsening sleep disturbances with frequent nocturnal awakening. These problems are attributed to chemotherapy or endocrine treatments induced by early menopause (3, 4).Obesity and severe or extreme obesity is becoming a complex health problem that healthcare providers must begin to address within the oncology community (5). Studies have shown that obese women constitute a high-risk population for developing post-menopause breast cancer, and it is estimated that up to half of breast cancers that develop after menopause are attributed to obesity (6).One third of breast cancer patients report that Cancer-Related Fatigue (CRF) has an adverse impact on their daily living activities (7).Quality of Life is a concept that receives a lot of interest from healthcare providers. QoL measures have been used to help identify problems associated with cancer, medical management, and effectiveness of rehabilitative interventions, and to set healthcare policy (8). Breast Health 2017; 13: 94-99 DOI: 10.5152/tjbh.2017.3342 94 ABSTRACT Objective: Many breast cancer survivors have unmet physical and psychological needs. Therefore, current study aimed to evaluate the impact of a lifestyle interventions program on fatigue, quality of sleep, quality of life (QoL), and body mass index (BMI) in women with breast cancer. Materials and Methods:This randomized controlled trial study (RCT) was carried between 2012 and 2015, and included 80 women with breast cancer. They were divided into two groups via a random allocation process: 40 women were allocated to the lifestyle interventions group, and 40 to the control group. Women in the lifestyle group received dietary energy-restriction training and practiced supervised aerobic exercises for 45-60 minutes three times per week throughout 24 weeks and the control group continued their routine life.Results: Differences between the two groups were significantly high for those who participated in the intervention group; this group reported significantly less fatigue, less BMI, improved QoL and better quality of sleep as compared to the control group (p<0.05). Conclusion:Breast cancer survivors may physically and psychologically benefit from participating in a healthy lifestyle interventions program. This program can help relieve fatigue, maintain healthy BMI, improve QoL and enhance the quality of sleep in...

“…Thus, for instance the EORTC, in addition to core cancer quality of life questionnaire, has developed several site-specific questionnaires including one for breast cancer (QLQ-BR23) [10] in order to collect more relevant patient-reported outcomes in studying quality of life in this group of cancer patients. The English-language versions of these questionnaires were successfully tested [10], it has been found to be reliable and valid in diverse cultures, including, the United Arab Emirates [11], Iran [12], China [13], Greece [14], Kuwait [15] and South Asia [16]. The EORTC QLQ-BR23 questionnaire was previously translated into Arabic but was not efficiently validated for use in patients speaking Moroccan dialect.…”

BackgroundQuality of life (QOL) and its measurement in cancer patients is becoming increasingly important. Breast cancer diagnosis and treatment are often associated with psychological distress and reduced QoL. In Arabic-speaking countries, QoL of patients with cancer is inadequately studied.The aim of this study was to test the reliability and validity of the Moroccan Arabic version of the European Organization for Research and Treatment of Cancer (EORTC) Breast Cancer-Specific Quality of Life Questionnaire (QLQ-BR23).MethodsAfter translation and cross-cultural adaptation, the questionnaire was tested on breast cancer patients. The participants’ number for the test and the retest were 105 and 37 respectively. Internal consistency was tested using Cronbach’s alpha coefficient (α), the test-retest reliability using intraclass correlation coefficients (ICC). Construct validity was assessed by examining item-convergent and divergent validity.ResultsThe questionnaire was administered to 105 patients. The mean age of patients was 48 years (SD: 16), 62.9% were married. 68.6% of all participants lived in urban area.The average time to complete the QLQ- BR23 was 15 min. Cronbach’s alpha coefficient, were all >0.7, with the exception of breast symptoms and arm symptoms. All items exceeded the 0.4 criterion for convergent validity except item 20 and 23 related to pain and skin problems in the affected breast respectively.ConclusionIn general, the findings of this study indicated that the Moroccan Arabic version of the EORTC QLQ-BR23 is a reliable and valid supplementary measure of the QOL in breast cancer patients and can be used in clinical trials and studies of outcome research in oncology.
