Toward a transdiagnostic tool to evaluate depressive symptoms across mental disorders: validation of the Calgary Depression Rating Scale in patients with major depressive disorder

Depressive symptoms in patients with schizophrenia are very prevalent and are associated with increased morbidity and mortality (Andrianarisoa et al., 2017). However, the evaluation of depressive symptoms in patients with schizophrenia needs specific tools to disentangle the overlap between depressive symptoms and negative and extrapyramidal symptoms (Collins et al., 1996; Goldman et al., 1992). Thus, the Calgary Depression Rating Scale (CDSS) was developed (Addington et al., 1992; Addington et al., 1990).
