Many studies have linked symptoms of depression after an acute myocardial infarction (AMI) to negative health outcomes, including mortality. It has been suggested, however, that this link may be due to biased measurement of depressive symptoms in post-AMI patients related to confounding with somatic symptoms related to AMI. The objective of this study was to validate a factor model for the Beck Depression Inventory-II (BDI-II) that would allow for modeling of depressive symptoms after explicitly removing bias related to somatic symptom overlap. ⋯ The G-S-C model is a novel approach to understanding the measurement structure of the BDI-II, presents advantageous statistical and interpretive properties compared to standard correlated factor models, and provides a viable mechanism to test links between symptoms of depression, as measured by the General Depression factor, and health outcomes among patients with AMI after explicitly removing variance from somatic symptoms unrelated to the General Depression factor.

This study aimed to evaluate the validity, reliability, and cultural relevance of the Cardiac Depression Scale (CDS) as a disease-specific screening tool for Chinese cardiac patients. ⋯ Empirical data support the C-CDS as a valid and reliable disease-specific tool in assessing depressed mood in Chinese-speaking patients with cardiac disease.

Our purpose was to determine if migraine, anxiety comorbidities, and chronic depression were independently related to health-related quality of life (HRQoL) in outpatients with major depressive disorder (MDD). ⋯ Future studies related to HRQoL of MDD should consider migraine and anxiety comorbidities simultaneously.
