Plants use sunlight to convert carbon dioxide and water into sugar and oxygen, but [we do] not invoke divine intervention to explain the process thermodynamics offers nothing to dampen our confidence in Darwinism.
To study this process evaluations are performed to recognize strong and weak aspects of an intervention, to explain observed (lack of) intervention effects, and to further improve an intervention prior to implementation, i.e. if an intervention turns out to be effective [ 16, 17].
Although valuable in their own right, such methods also offer the opportunity to enrich more traditional approaches to assessing interventions, helping to explain why some interventions are unsuccessful, or why they seem to work effectively in some contexts but not in others.
The intervention will include appropriate theory-based mediator variables of target components associated with the intervention techniques to explain the processes behind the proposed intervention effects.
The approach goes beyond simply evaluating whether or not an intervention worked to explain why it led to observed outcomes [ 2].
All eligible participants will be seen by the principal investigator (PI) 1-4 weeks before the start of the interventions to further explain the study, to confirm eligibility, and provide informed consent.
To date, few childhood obesity interventions have been implemented in the ROI and interventions are unlikely to explain why childhood overweight and obesity rates may be stabilising.
Researchers have suggested a variety of interventions and mechanisms to explain these improvements.
Elucidating the theory, content, and delivery of interventions may help to explain the heterogeneity in effect sizes usually observed in systematic reviews and, thereby, to identify what works and what does not, which provides the evidence needed to direct clinical care and research.
