| description | Abstract Background One of the emotional problems in patients experiencing cancer is demoralization syndrome. Concerning the importance of demoralization in patients with cancer, having a valid and reliable scale for assessing this problem is crucial. A revised version of Demoralization Scale (DS-II) was designed in 2016. It was necessary to determine its validity and reliability in populations with different cultures. This study aimed to determine the psychometric properties of the Persian version of DS-II (PDS-II) in Iranian patients with cancer. Methods The study population comprised 170 Iranian patients with cancer in Ardabil, Iran. The inclusion criteria were: age 18 or more, ability to understand and speak Persian, willingness to consent to participate in the study, having healthy cognitive function, and having an awareness of cancer. To determine the psychometric properties of PDS-II, the content, convergent, construct, and discriminant validity, besides internal consistency, were evaluated. Results Regarding the high correlation of PDS-II with General Anxiety Disorder, Patient Health Questionnaire, Beck Hopelessness Scale, and Hospital Anxiety and Depression Scale, the convergent validity of the PDS-II was confirmed. Confirmatory factor analyses confirmed both the original 2-factor and one-factor models of PDS-II. Internal discriminant validity of the PDS-II was not confirmed because the Average Variance Extracted from two dimensions of PDS-II (AVE = 0.31 and 0.37) was less than the square correlation between these two dimensions (r2 = 0.79). Cronbach α and coefficient was 0.88 for the PDS-II. Conclusions PDS-II is a valid and reliable scale for measuring demoralization among Iranian people with cancer. However, the discriminant validity of the PDS-II was not supported. |
