Health and Quality of Life Outcomes 2010 8 106 http www.hqlo.eom content 8 1 106 HEALTH AND QUALITY of life outcomes RESEARCH Open Access The ChQoL questionnaire an Italian translation with preliminary psychometric results for female oncological patients Giovanni Aschero 1 Flavio Fenoglio1 Maria Giuseppina Vidili1 Andrea Wussler2 Abstract Background in Occidental languages no widely accepted questionnaire is available which deals with health related quality of life from the specific point of view of Traditional Chinese Medicine TCM . Some psychometric tools of this kind are available in Chinese. One of them is the Chinese Quality of Life questionnaire ChQoL . It comprises 50 items subdivided in 3 Domains and 13 Facets. The ChQoL was built from scratch on the basis of TCM theory. It is therefore specifically valuable for the TCM practitioner. This paper describes our translation into Italian of the ChQoL its first application to Occidental oncological patients and some of its psychometric properties. Methods a translation scheme originally inspired by the TRAPD procedure is developed. This scheme focuses on comprehensibility and clinical usefulness more than on linguistic issues alone. The translated questionnaire is tested on a sample of 203 consecutive female patients with breast cancer. Shapiro-Wilk normality tests Fligner-Killeen median tests exploratory Two-step Cluster Analysis and Tukey s test for non-additivity are applied to study the outcomes. Results an Italian translation is proposed. It retains the TCM characteristics of the original ChQoL it is intelligible to Occidental patients who have no previous knowledge of TCM and it is useful for daily clinical practice. The score distribution is not Normal and there are floor and ceiling effects. A Visual Analogue Scale is identified as a suitable choice. A 3-point Likert scale can also efficiently describe the data pattern. The original scales show non-additivity but an Anscombe-Tukey .
