Resilience and Depressive Symptoms in Adults With Cardiac Disease: A Systematic Review.
Amy Ketcham, Austin Matus, Barbara Riegel
PMID 37707965WHAT IT FOUND
Ten of 13 studies in adults with cardiac disease found higher resilience linked to fewer depressive symptoms.
Because the studies only looked at associations, this does not show resilience prevents depression.
Key findings
01Ten studies found that higher resilience was associated with lower depressive symptoms.
02Three studies found no significant relationship between resilience and depressive symptoms.
03One study found that when high resilience was present, depressive symptoms did not lead to poor self-care maintenance.

What it does not show
The included studies were observational, so they cannot show that resilience causes lower depressive symptoms. Resilience and depressive symptoms were measured with many different scales, which made the results hard to compare. The three longitudinal studies were poor quality, and two lost more than 20% of their original sample. Blinding of assessors was unclear because none of the studies explicitly addressed blinding. Only nine studies statistically accounted for confounding variables, and several used simple correlations. The search was limited to English-language studies, which may have missed relevant research. Inter-rater agreement was not addressed at the title and abstract review.
Declared interests
The authors report no conflicts of interest.
The easy way to misread this
Do not conclude that building resilience will reduce depressive symptoms in cardiac patients. The review included observational studies, so it shows association only.
