Abstract

Frailty is highly prevalent among older adults. This study aims to add evidence to the mediational role of depression in the pain-frailty relationship. Data came from a sample of 2578 Spanish older adults recruited from the Survey of Health, Aging, and Retirement in Europe (SHARE). A set of competing structural equation models were performed: (a) independent prediction, (b) full mediation, and (c) partial mediation. Results showed a better fit for the partial mediation model. This model was extended including covariates. The effects of pain and depression remained relevant in the final model, which explained 91% of the frailty variance. These findings support the relevance of the pain-depression dyad in frailty development. Although the pain shows a direct impact on frailty, this association is partially mediated by depression. The interplay of these conditions could be crucial for treatment effectiveness.
