Demoralization in patients with cancer: Validation of the French version of the demoralization scale I (DS-I)

This study focused on the phenomenon of demoralization, an experience of emotional distress frequently observed in patients with severe chronic illnesses, particularly those with cancer.

The aims of this study were to adapt a standard instrument for assessing demoralization - the Demoralization Scale I (DS-I) - into French and to examine its content validity.

First, we developed a French version of the Demoralization Scale I through forward and backward translation procedures. Second, we conducted a qualitative thematic study based on cognitive interviews with 12 French patients with cancer to assess the content validity of our French translation of the Demoralization Scale I.

Our French version of the Demoralization Scale I seemed satisfactory in light of the COSMIN methodological recommendations for the translation of instruments. Our version of the Demoralization Scale I also demonstrated an acceptable content validity through the cognitive interviews conducted with patients.

Our findings suggest that further validation of the French version of the Demoralization Scale I should be continued in future studies. This would ensure rapid diagnosis of demoralization in affected patients and the initiation of therapeutic interventions.
