    Given the high prevalence of emotional disorders within patients withcancer, identifying these comorbidities is essential in providing patientcentric care within a multidisciplinary team environment. TheDepression Anxiety Stress Scale Short Form (DASS)‐21 is an empiri-cally developed self‐report measure which assesses anxiety, depres-sion and stress. The conceptual basis of DASS is a tripartite model1comprising 3 subscales: anxiety (DASS‐A—autonomic arousal,physiological hyperarousal, and situational anxiety), depression(DASS‐D—anhedonia, hopelessness, and dysphoria) and stress(DASS‐S—nondiscriminating anxiety and depression items that pre-dominantly consisted of tension, nervous arousal, and irritability) andprovides a global measure of psychological distress.

    Because of the positive psychometric properties and ease of use,1the DASS‐21 is increasingly used in a cross section of oncology set-tings to assess psychological distress but has not been validated inthe cancer population. Our study aimed to examine the assumptions of the structure ofthe DASS‐21 within a cancer population actively receiving chemother-apy treatment in an outpatient setting and evaluate its psychometric properties.
