This paper presents the rationale and need for MHBC research and interventions, briefly reviews the research base, and identifies core conceptual and methodological issues unique to this growing area.
For example, when faced with an evidence review on unplanned hospital admissions, the committee scanned through the interventions and briefly discussed one intervention with inconclusive evidence, which a member subsequently stated was a "good idea".
In Experiment 1, a longitudinal field experiment in a fundraising organization, callers in an intervention group briefly interacted with a beneficiary; callers in two control groups read a letter from the beneficiary and discussed it amongst themselves or had no exposure to him.
23 The background behind the intervention was briefly as follows.
Additional details for each study regarding aim, start-up, and design are given in the ensuing four subsections; the multi-facetted nature of the interventions is briefly described.
There is also evidence that lower genital tract infections, especially bacterial vaginosis, or maternal systemic infections such as periodontitis, malaria, and syphilis contribute to preterm birth (see article 3 on interventions), as briefly reviewed below relevant to pathophysiology.
The specific intervention protocols are briefly summarized below, since they are described in detail elsewhere [ 23].
[Response] Question 2: Testing or piloting the intervention Can you briefly describe how the intervention was tested or piloted prior to being evaluated in your trial?
Administrative study staff (not intervention staff) meet briefly (approximately 15 min) with the SG participants once individually to give them their binder and to provide an orientation to its layout and contents.
Figure 1 is a flow diagram illustrating the progress of student recruitment and data collection in both groups from baseline to study completion.> The development and design of the intervention are described briefly in this section, more details are found elsewhere [ 13].
