Representative stakeholder involvement along with processes to support constructive debates of the evidence would ensure more valid interpretation of the research evidence within the wider clinical and social context, as well as help PRCs negotiate the competing functions of the prenatal records in a way that maximizes benefits to patient and population health outcomes.
Haist believes the fMRI data is far more valid than much of the scientific evidence which has been presented during the two trials so far.
To classify more valid and less valid information, the 'levels of evidence' specify a hierarchical order for various research designs based on their internal validity.
There is no evidence that the BDI-II is more valid or reliable than other depression scales, and public domain scales such as the Patient Health Questionnaire – Nine Item (PHQ-9) has been studied as a useful tool.
I know best the upshot in my own field: It took more than 30 years for the scientific community to accept valid evidence that humans are not like mice with respect to the details of X inactivation.
Making neuroimaging reproducible will not make studies better; it will make scientific conclusions more verifiable, by accumulating evidence through replication, and ultimately make those conclusions more valid and research more efficient.
Generally, the more issues from both sides of the ladder are considered in a mediational study, the more valid conclusions can be drawn about mediation relations and the strength of evidence.
However, such an approach would sideline other valid evidence [ 3, 9- 11, 28, 30] resulting in a more mechanistic process.
Further more, stratification of the initially planned surgical procedure and sphincter-preservation will generate valid evidence whether RCT will allow a less aggressive (sphincter saving) surgical approach.
"There is increasing evidence that engaging communities actually makes the research more powerful, more important, and more valid, and the potential to develop advocacy approaches to do public health intervention and change is more effective".
