This document provides a list of questions to evaluate a quantitative research article on how maternal stress during pregnancy impacts child cognitive development. The questions address the research problem, hypotheses, methodology, data collection and analysis, conclusions, and strengths and limitations of the study. Researchers are asked to obtain a peer-reviewed research article on this topic and use the evaluation questions to analyze the article in an APA-formatted 2-3 page paper.

stress during pregnancy impact the cognitive development of a child?Obtain a peer-
reviewed quantitative research article. Use APA format to reference your research article.
You may select an article that is relevant to your literature review.The following list of
questions may be used as a basis for evaluating a research article. This is not a set model but
an outline to help evaluate published research. Your evaluation should include a cover page
and at least 2-3 pages in length. Make sure you cite your source accordingly.What is the
problem?Is it significant?Is it properly delimited?Is it clearly described or implied?Are
assumptions and limitations recognized?What is the independent variable?What is the
dependent variable?Are the independent and dependent variables stated in the article
title?What is/are the hypothesis/hypotheses?Are hypotheses made explicit?Are hypotheses
clear?Does the study have practical or theoretical value?Does the hypothesis lend itself to
empirical testing?Can data be obtained?What are the methods or procedure?Is the method
appropriate to the hypothesis? Explain why.If the method is no appropriate to the
hypothesis, explain what might have been a better approach, and why.Do procedures follow
an orderly, logical sequence? Explain.Is there evidence of review of previous studies to
indicate context of this study in related body of knowledge?Are research procedures
described in detail to permit verification or replication?What information is provided about
the participants?How many subjects participated in the study?Are the participants studied a
representative case sample?What evidence is given about sampling techniques?Are there
sufficient numbers of participants for observation?Was approval to conduct the study
obtained? From whom?Did participants sign an informed consent?What source of data is
identified?Are data-gathering devices appropriate? Could other instruments be used?Are
measuring devices valid and reliable?Are sufficient amounts and appropriate kinds of data
obtained?How is the data recorded?How are the data analyzed?What logical consequences
were deduced from the hypothesis?Was an appropriate significance test applied to the
findings?What was the nature of the analysis? (verbal description, statistical manipulation,
tables of frequency counts, etc.)What important conclusions are presented?Were the
conclusions sound according to the data?Did the conclusions conform to good logic; were
they internally consistent, free from self-contradiction?What are the positive aspects of this
research?What are the negative aspects of this research?How do you evaluate the written
report?Is the style clear, objective, and readable?Is the article long enough to adequately
cover the topic?Are the tables and/or figures helpful in clarifying the information?Could the
