Title
The article is titled “Sociodemographic Predictors of Antenatal and postpartum depressive symptoms among Women in a medical group practice,” which fully covers the research question and the topic of the work and provides information about the target group of the study. However, from the point of view of reader appeal, the stated title is not attractive.
Abstract
Yes, the abstract is quite brief and clearly postulates the main sides of the research question. The introduction introduces the reader to the discourse of the problem well enough and shows the lack of knowledge of the research question. It is clear from the introduction that the research is related to the PICO question. However, it is not clear from the introduction precisely what methods were used.
Literature Review
The paper does not present a separate literature review section, but studies are cited both in the introduction and discussion. This fairly reliably describes existing information and cites it as needed. In addition, the introduction reports a knowledge deficit on the problem under study, which can be attributed to postulating the need for additional research.
Conceptual, theoretical framework
The theoretical framework of the study is postulated in the introduction when setting the general tone for future sections; the mechanism of variables, including maternal SES and tendencies toward postpartum depression, is explained there.
Research question(s) or hypothesis
Neither the hypothesis nor the research question is clearly framed. After reading the introduction, a general idea of the direction of the study is created, which only allows us to assume the author’s hypothesis.
Research design
There was no discussion of methodological design, but the procedures followed and sampling mechanisms were described in detail. The only validity check was to identify proven signs of depression in women during pregnancy based on clinical information.
Population and sample
The sample was described reliably, while the discussion of the total population could have been expanded. There was no power analysis and consequent justification of sample size. Nor was there any indication of the specific sampling mechanism chosen as the best.
Data collection and measurement
The use of questionnaires and interviews was described as the best mechanism for data collection, and the choice of specific questionnaires was justified by their academic value. Thus, the conceptual and operational definitions coincided. The validity of the data collection methods used was justified only by citing their respective academic value.
Procedures
Minimizing bias was based on verifying respondents’ clinical information, and procedures were described reliably enough — but not wholly — for another researcher to replicate them. Staff training and ethical aspects of the methodology were not reported.
Data analysis
Given the nature of the variables, logistic regression was used as an appropriate statistical tool. The limiting factors and their potential impact on the results were discussed and covered by reanalysis, taking into account additional variables.
Findings
The results were detailed and fragmented into four sections, each examining a specific relationship. Numerical tables were presented in the paper, and a diagram was provided. However, there were no diagrams or other graphics. In addition, the authors did not report errors of the I and II type, nor did they postulate the statistical significance of the results.
Interpretation of the findings
The results are described in detail both independently and in the context of previously published articles; a comparison of results is made. Extrapolation of the results to the overall scale of the target group is discussed but not formulated separately.
Implications, limitations, recommendations
The limitations of the study are described in detail and justified by the chosen nature of the methodology. The implications of the work were summarized in a separate text box but not discussed in detail. Recommendations for further research are not formulated.
Presentation
The writing style and citation of academic resources are thorough, the text is well-read, and major conclusions are postulated in separate text boxes. The authors acknowledge the broad limitations of the results, which facilitates critical reflection on the findings. With the exception of the lack of postulating the statistical significance of the results, the visual design of the collected sample with charts, and the detached literature review section, all other parts of the material are easy enough to understand and leave no questions after reading. The reading itself was interesting, although after re-reading it, the feeling lingers that the material could have been more intriguing.
Summary
The article provides information on the extent to which SES affects labor and postpartum depression, which is consistent with the stated PICO question. The material conducts logistic regression to estimate the mutual influence of the variables and answers the stated question. It is difficult to verify whether the results are valid because regression methods require p-values to be able to extrapolate results to the general population; this information was not provided. However, the authors refer to OR and CI as tools to increase the reliability of the results obtained, so we can conclude that within the current sample, the results are reliable. To broaden the scope of the study described in light of the PICO question, it would be helpful to answer some additional research questions, specifically how education affects postpartum depression and what is the correlation between age and depression tendency, namely, whether the relationship between these two variables can be predicted.
