Abstract

Introduction and objective Managing chemotherapy-induced nausea and vomiting (CINV) in patients with cancer is still a challenge for the patients and also the clinicians. The Multinational Association of Supportive Care in Cancer (MASCC) has developed a scale for better measurement and management of CINV. Thus, this paper aims at translating the scale into Persian and assessing the psychometric properties of the proposed translated version of MASCC Antiemesis Tool (MAT). Methods Having received the necessary permissions and complying with the Forward-Backward translation protocol, we conducted a qualitative assessment of the face validity through cognitive interviewing and content validity assess with 5 experts in Persian Literature. Internal consistency using Cronbach's Alpha Coefficient was applied to determine the scale reliability. In order to determine the construct validity, the three methods of exploratory factor analysis, known group analysis, and convergent validity (assessment of the correlation between Rhodes Index of Nausea, Vomiting and Retching (INVR) scale and the Persian version of MAT scale) were conducted on 300 participants. Results About 300 patients with a mean age of 50.73 +/- 0.81 participated in the study. The results showed a significant difference in the index of nausea and vomiting between the patients who are below 50 years old and those who are above 50 (P = 0.0001). The Cronbach's Alpha Coefficient was reported 0.88 for the whole MAT questionnaire. Due to the low factor load (fewer than 0.5) for question 1, it was removed in the factor analysis. Besides, exploratory factor analysis (EFA) led to the exploration of the two factors of nausea and vomiting. Conclusion According to the results of the study, the Persian version of the MAT questionnaire is considered as a highly reliable and valid tool, in order to efficiently and accurately measure chemotherapy-induced nausea and vomiting and to better manage this side effect.
