Assessing Research Quality

Related Information

The quality of social science and policy research can vary dramatically. Research Connections accepts all research and related documents that are disseminated in the field, without judging the quality of their design, methods, findings and general content. It is essential, therefore, that consumers of Research Connections research evaluate the quality of these studies.

Key Questions to Ask

  1. Was the research peer reviewed?

    Peer reviewed research studies have already been evaluated by experienced researchers with relevant expertise. Peer-reviewed research is usually of high quality. A research consumer, however, should still critically evaluate the study's methodology and conclusions. The Research Connections Web site indicates whether a study has been peer reviewed.

  2. Can a study's quality be evaluated with the information provided?

    Every study should include a description of the population of interest, an explanation of the process used to select study subjects, definitions of key variables and concepts, descriptive statistics for main variables, and a description of the analytic techniques. Research Connections users should be cautious when drawing conclusions from studies that do not provide sufficient information about these key research components.

  3. Are there any potential threats to the study's validity?

    A valid study answers research questions in a scientifically rigorous manner. Threats to a study's validity are found in three areas:
