Cascade diagrams for depicting complex interventions in randomised trials.
Manymedical interventions—particularly non-pharmacological ones—are complex, consisting of multiple interacting components targeted at different organisational levels. 2 Published descriptions of complex interventions often do not contain enough detail to enable their replication. Reports of behaviour change interventions should include descriptions of setting, mode, intensity, and duration, an...
متن کاملRandomised controlled trials of complex interventions
Although all randomised controlled trials (RCT) share much in common in terms of design, conduct, analysis and reporting, trials of complex interventions (loosely “interventions with several interacting components”) can have special issues which need appropriate consideration to deliver high quality and credible evidence to change or inform practice. For example, blinding the intervention may b...

متن کاملProcess evaluations for cluster-randomised trials of complex interventions: a proposed framework for design and reporting
BACKGROUND Process evaluations are recommended to open the 'black box' of complex interventions evaluated in trials, but there is limited guidance to help researchers design process evaluations. Much current literature on process evaluations of complex interventions focuses on qualitative methods, with less attention paid to quantitative methods. This discrepancy led us to develop our own frame...
متن کاملMediation and moderation of treatment effects in randomised controlled trials of complex interventions.
Complex intervention trials should be able to answer both pragmatic and explanatory questions in order to test the theories motivating the intervention and help understand the underlying nature of the clinical problem being tested. Key to this is the estimation of direct effects of treatment and indirect effects acting through intermediate variables which are measured post-randomisation. Using ...
