The participants were selected using convenience sampling and completed the McGill quality of life, demoralization, positive and negative affect, state hope and patient health questionnaires. Data were analyzed using SPSS-24 and LISREL software. Descriptive statistics, Cronbach's alpha, Pearson's correlation coefficient and confirmatory factor analysis were used for data analysis.
Results: Internal consistency was obtained by calculating Cronbach's alpha coefficient for subscales of physical (0.92), psychological (0.96), existential (0.94), social (0.95) subscales and total score (0.97), which indicated good reliability of this scale. Also, Confirmatory Factor Analysis (CFA) results showed that the four-factor model of MQOL-R is a good fit.
