AB Breast cancer impacts the psychological well-being of women, leaving them at risk of developingdepression, anxiety, and other stress-related disorders. The Depression Anxiety Stress Scales (DASS21) is a widely used measure, although empirical evidence regarding its psychometric propertiesin the breast cancer population is limited. The purpose of this study was to conduct an exhaustiveanalysis of the psychometric properties of the DASS-21 in a sample of Spanish women diagnosed withbreast cancer. Participants were 289 breast cancer patients who completed the DASS-21 and otherquestionnaires measuring life satisfaction, positive and negative afect, fourishing, perceived stress,and breast cancer-specifc stressors. In terms of validity evidence based on the internal structure ofthe DASS-21, adequate ft indices were obtained for the model based on three frst-order factors(depression, anxiety, stress) and one second-order factor (general psychological distress). Reliabilitycoefcients (McDonald’s omega) ranged from .84 to .95. Validity evidence based on relationships withother variables was also provided by moderate and strong correlations with well-being indicatorsand stress measures. The results support the use of the DASS-21 for measuring general psychologicaldistress in the breast cancer context, where it may provide useful information for the design ofpsychological interventions with patients.
