Résumé
Demoralization is a syndrome of existential distress and despair in patients with cancer and other severe medical illnesses. The Demoralization Scale (DS-II) is self-administered and contains 16 items, and it has two factors: meaning and purpose and distress and coping ability. Women with breast cancer (240) completed the scales DS-II, positive and negative affect, state hope, patient health, and quality of life. Confirmatory factor analysis (CFA) and divergent and convergent validity were used to measure the construct validity of DS-II. CFA was chosen to check the fit of the two-factor model. Divergent and convergent validity were investigated using Pearson's correlation test. The reliability of DS-II was evaluated by the internal consistency method. Cronbach's alpha was used to calculate the internal consistency of the DS-II. The Cronbach's alpha coefficient for the subscales of meaning and purpose, distress and coping ability, and the total score was obtained: 0.67, 0.72, and 0.81, respectively, indicated this scale's good reliability. Furthermore, the Pearson correlation coefficient results showed the appropriate convergent validity and good divergent validity of the DS-II. The DS-II has sound psychometric properties and can be recommended as a reliable tool for assessing demoralization in women with breast cancer.

Background
UNASSIGNED
Demoralization is a syndrome of existential distress and despair in patients with cancer and other severe medical illnesses. The Demoralization Scale (DS-II) is self-administered and contains 16 items, and it has two factors: meaning and purpose and distress and coping ability.
Materials and Methods
UNASSIGNED
Women with breast cancer (240) completed the scales DS-II, positive and negative affect, state hope, patient health, and quality of life. Confirmatory factor analysis (CFA) and divergent and convergent validity were used to measure the construct validity of DS-II. CFA was chosen to check the fit of the two-factor model. Divergent and convergent validity were investigated using Pearson's correlation test. The reliability of DS-II was evaluated by the internal consistency method. Cronbach's alpha was used to calculate the internal consistency of the DS-II.
Results
UNASSIGNED
The Cronbach's alpha coefficient for the subscales of meaning and purpose, distress and coping ability, and the total score was obtained: 0.67, 0.72, and 0.81, respectively, indicated this scale's good reliability. Furthermore, the Pearson correlation coefficient results showed the appropriate convergent validity and good divergent validity of the DS-II.
Conclusion
UNASSIGNED
The DS-II has sound psychometric properties and can be recommended as a reliable tool for assessing demoralization in women with breast cancer.
