Title: Fear of childbirth, anxiety and depression in three groups of primiparous pregnant women
not attending, irregularly attending and regularly attending childbirth preparation classes
Version: 2Date: 05 Jun 2020
Reviewer's report:
My comments do not appear to be listed or addressed - I wonder whether the authors ever received
them? I include them here:
In the "Study design and participants" section, it sounds like it's an randomized trial but it isn't (i.e.
women were "assigned" to three groups). Please state that more clearly here. Maybe replacing thiswith "women's attendance was used to create three categories, defined as follows…"
Why was history of depression and stressful events in the family exclusionary? I imagine this
would be a fairly high percentage of the population, which would introduce unnecessary bias inyour sample. This potential for bias should be acknowledged in the limitations section. Also, howwere these variables assessed?
Related to the above point, more details about how many participants were excluded for each
reason would provide a better picture of how generalizable this sample is. Providing a CONSORTparticipant flow diagram would be ideal.In Table 1, the authors make reference to marital satisfaction and spousal support - how were theseassessed? This information should be added to the methods. I find it curious that "Too much" is anoption for marital satisfaction? What does that mean - it would be good to know the question that
was posed.
A paragraph in the methods section should be devoted to describing the intervention. How many
participants to a group? How many sessions? Does it follow a set structure? If so, it would be niceto know the topics covered at each class. The more details that can be provided, the more theseresults will be clinically meaningful to others who are considering establishing a similar program.How do the authors make sense of the fact that irregular attendance was just as effective as regularattendance? Does this suggest that the full course could be shortened and be just as effective? Thisshould be discussed in the discussion section.
The fact that this is not a randomized trial should be added to the limitation section.
