Depression Moderates Physical Functioning Over Time in Survivors of Cancer

TL;DR: In addition to making criteria-based diagnoses of depressive disorders, the PHQ-9 is also a reliable and valid measure of depression severity, which makes it a useful clinical and research tool.

TL;DR: In this paper, the authors present a discussion of whether, if, how, and when a moderate mediator can be used to moderate another variable's effect in a conditional process analysis.

TL;DR: 2 general approaches that come highly recommended: maximum likelihood (ML) and Bayesian multiple imputation (MI) are presented and may eventually extend the ML and MI methods that currently represent the state of the art.

TL;DR: Evidence is presented that performance measures can validly characterize older persons across a broad spectrum of lower extremity function and that performance and self-report measures may complement each other in providing useful information about functional status.
