The Psychometric Properties and Clinical Use of the Turkish Version of the Functional Assessment of Cancer Therapy–Lung (FACT-L) Scale

Abstract

Objectives:psychometric properties of the Turkish version of the Functional Assessment of Cancer Therapy-Lung (FACT-L) scale and the sensitivity to changes in clinical indicators. Patients and Methods:This study was conducted within the framework of a national multicentre project. Patients with either stage IIIB or IV primary lung cancer diagnosed after April 2010were included in thisstudy. A classical confirmatory approach was used for both the reliability and validity analyses. Internal consistency was tested using Cronbach's α value, and the validity analysis was performed using construct validity and clinical validity. Results:276 (92.3%) patients were male and the average age was 60.8 ± 9.4 years. The most frequently observed histological type was squamous cell carcinoma (36.8%), and 61.5% of these stage IV tumours. Cronbachs α values for the subscales ranged from 0.60 to 0.84. The majority of the FACT-L subscales revealed inter-scale correlation coefficients greater than 0.35. All sub-dimensions, except that of the social/family well-being scale, are able to significantly discriminate between stages IIIB and IV. Significantly lower scale scores were detected in patients with stage IV than stage IIIB. The comparative fit index was 0.917, and the root mean square error of approximation was 0.091. Dyspnoea, haemoptysis, chest pain, weight loss, anorexia, localised pain, and fever symptoms had a significant correlation with the FACT-L, trial outcome index, and lung cancer subscale. Conclusion:Turkish version of the psychometric properties of the original FACT-L scale is regarded as a valid and reliable tool and can be used safely in a clinical context when managing patients with lung cancer in Turkey.

Factors Associated with Poor Quality of Life in Lung Cancer Patients Undergoing Chemotherapy in Erbil City

“…Cigarette smoking appears to be a risk factor that influences the quality of life of patients with lung cancer [20] in this study demonstrated that patients who smoked previously are three times more at risk for developing lung cancer than non-smokers and had significant impacts on quality of life. Patients with stage III lung cancer had significantly better physical well-being, higher social well-being, emotional status, well-improved-functioning status, and better ability to control Lung Cancer symptoms which agrees with a study done in Turkey when considering the stage of the tumor, the scale scores varied significantly in all dimensions among patients with stage III cancer [21] . In addition, the study done in China by [22] found that stage IV lung cancer patients had lower all domains of FACT-L scores than stage III patients.…”
