Interrelations between participant and intervention characteristics process variables and outcomes in online interventions: A protocol for overarching analyses within and across seven clinical trials in ICare

摘要

BackgroundIt is well known that web-based interventions can be effective treatments for various conditions. Less is known about predictors, moderators, and mediators of outcome and especially interrelations between participant and interventions characteristics, process variables and outcomes in online interventions. Clinical trials often lack statistical power to detect variables that affect intervention effects and their interrelations. Within ICare, we can investigate the interrelation of potential predictor and process variables in a large sample.
