Abstract Objective The Functional Assessment of Cancer Therapy—Cognitive Function (FACT-Cog) is a questionnaire that is used to evaluate the quality of life and cognitive functions according to individual self-reports. The aim of this study was to investigate the validity and reliability of the Turkish version of the FACT-Cog. Methods Cancer patients who were treated with chemo or radiotherapy and had a score of 24/30 and more in Mini-Mental State Examination (MMSE) were included in this study. Cognitive functions assessed with the FACT-Cog and the European Organization of Research and Treatment of Cancer Quality of Life Core Questionnaire Core 30: Cognitive Function subscale (EORTC QLQ-CF). Results One hundred and forty cancer patients [female = 87 (62.1%), male = 53 (37.9%)] were included. The mean age of the participants was 47.93 ± 11.90 years. The Cronbach's α of the FACT-Cog scale was 0.82. Test–retest intraclass correlation coefficient values of the FACT-Cog questionnaire were varied from 0.855 to 0.954. There were found low correlations between the total score of the FACT-Cog and the MMSE (r = 0.26, p = 0.002), and moderate correlations between the EORTC QLQ-CF subscale and the FACT-Cog (r = −0.43; p < 0.001). Significance of results It showed the validity and reliability of the Turkish version of the FACT-Cog questionnaire for cancer patients. It may be beneficial to use this questionnaire for the effects of cancer treatment.

Validity And Reliability

PURPOSE This is the first published report on the validation of the Functional Assessment of Cancer Therapy-Breast (FACT-B), a 44-item self-report instrument designed to measure multidimensional quality of life (QL) in patients with breast cancer. The FACT-B consists of the FACT-General (FACT-G) plus the Breast Cancer Subscale (BCS), which complements the general scale with items specific to QL in breast cancer. The FACT-B was developed with an emphasis on patients' values and brevity and is available in nine languages. METHODS AND RESULTS Two validation samples were used for this report. The first (n = 47) was tested twice over a 2-month period to assess sensitivity to change. Significant sensitivity to change in performance status rating (PSR) was demonstrated for the FACT-B total score, the Physical Well-Being (PWB) subscale, the Functional Well-Being (FWB) subscale, and the BCS. Sensitivity to change in QL as measured by the Functional Living Index-Cancer (FLIC) was documented in the FACT-B total score, PWB, FWB, and Emotional Well-Being (EWB). Additional validity and reliability data were obtained from a larger sample (n = 295). The alpha coefficient (internal consistency) for the FACT-B total score was high (alpha = .90), with subscale alpha coefficients ranging from .63 to .86. Evidence supported test-retest reliability, as well as convergent, divergent, and known groups validity. CONCLUSION The FACT-B is appropriate for use in oncology clinical trials, as well as in clinical practice. It demonstrates ease of administration, brevity, reliability, validity, and sensitivity to change.

Colorectal Cancer Patients

Abstract Background: Colorectal cancer and its treatments can have a detrimental effect on patients’ quality of life. The European Organization for Research and Treatment of Cancer Quality of Life questionnaire (EORTC-QLQ) was developed to assess quality of life among colorectal cancer patients and is used worldwide. However, the tool has not been translated into a local language or validated in the Ethiopian context. Therefore, this study aimed to examine the psychometric properties of the EORTC-QLQ in Ethiopia among colorectal cancer patients.Methods: A cross-sectional study was conducted in a major referral hospital in Addis Ababa, Ethiopia from March to May, 2020. A total of 158 colorectal cancer patients were consecutively included. The construct validity was assessed using Multitrait Scale Analysis, convergent validity, and relationship with functional outcomes. The internal consistency was examined using Cronbach’s alpha.Result: Among the participants, 52.2% were men, with a median age of 46 years (IQR = 17.7 years). The time needed to complete the EORTC-QLQ was less than 20 minutes. The item-total correlation alpha values ranged from 0.47–0.91. All item correlations within their scales were greater than 0.4 except for the Blood and Mucus in Stool scale. The value of correlation coefficients between all items and their own domain were higher than other domains, except for the Blood and Mucus in Stool scale. The correlation between the core questionnaire and the colorectal tool ranged from -0.453–0.581. The tool showed a significant difference between stoma and non-stoma patients, and between patients who had good physical function and those who did not.Conclusion: Except for the Blood and Mucus in Stool scale, the construct validity and reliability of all scales were supported. Therefore, the Amharic version of the tool can be used to assess health related quality of life in Ethiopian colorectal cancer patients. However, due to the low correlation between items in the Blood and Mucus in Stool scale, we recommend that these items are treated as a single item.

Conceptual Equivalence

Abstract BackgroundThe Functional Assessment of Cancer Therapy Scale Brain Cancer-Specific Module (FACT-Br) was developed by a standard measurement theory and used to assess the symptoms, functions, and quality of life among brain cancer patients in English spoken countries. However, this instrument has not been translated into Chinese.ObjectiveThis study aimed to develop the Chinese version of the Functional Assessment of Cancer Therapy Scale Brain Cancer-Specific Module (C-FACT-Br).MethodsC-FACT-Br was translated following the standard Functional Assessment of Chronic Illness Therapy Translation (FACIT) methodology. Then, the cognitive briefing interviews were done to ensure the conceptual equivalence by probing 10 native Chinese-speaking brain cancer patients.ResultsThe translation was finished by bilingual teams with the help of the FACIT organization. All items in C-FACT-Br were understandable to patients, and they also gave some comments in adjusting items in scale.ConclusionsC-FACIT-Br items had the equivalence meaning, same structure, and harmonization with the English version. Brain cancer patients over 18 years old can understand the scale and express their symptoms, function, and quality of life by these measures.
