The treatment sequence is controlled by a microcontroller (Atmel AT89S8252, Fribourg, Switzerland), that is, duration of session, sequence of modulation frequencies and duration of each sequence can be programmed via PC over a RS232 interface.
For this study, the appropriate control condition should include a group of patients who should be involved in a session sequence inducing placebo effect (the same number of sessions as in the aerobic exercise training, but with no nearly specified occupation during each session).
On the second day, the three-session sequence was repeated, but the visual and/or odor cue conditions were replaced by novel cue elements.
The effectiveness of this temporal within-session sequence was questioned by the authors and it was noted that the literature is unclear on the best approach.
The other risk intervention components: smoking, ETSE, and IPV, thus were modified so they could be similarly delivered over a 10-session sequence.
Before beginning the intervention, we tested the 6 session sequence with a group of 4 mothers who met the criteria for inclusion in the study but who were not participants in the final trial.
The original group therapy model was adapted in DC-HOPE to an individual treatment format that consisted of an 8-session sequence delivered at the clinic in conjunction with prenatal visits.
While the Parker model was designed for delivery in one visit, the Project DC-HOPE adaptation enabled monitoring each woman's progress over a 10-session sequence in developing a safety plan and considering options to remaining with her partner.
In each playback session, sequences of 'haa' calls of a male and female raven were presented simultaneously from two different locations, whereby the played-back individuals varied in the degree of familiarity to the local ravens.
To address the stability of the component maps across recording sessions, the sequence of 4 templates identified from the GAs was fitted back to the 9 individual recordings (a summary of the raw voltage maps can be found in Online Resource Supplementary Figures 1 and 2).
