Here's how thematic synthesis can be applied in a systematic review with diverse study designs:
Data Extraction: Researchers systematically extract relevant data from each included study, regardless of the study design. This may include qualitative quotes, quantitative results, descriptions of interventions or exposures, outcome measures, and key findings.
Coding and Theme Development: The extracted data are then coded, typically using a qualitative coding approach. Codes are assigned to segments of data that represent meaningful concepts or themes related to the research question. These codes can come from various types of data, such as qualitative interviews, survey responses, or statistical results.
Thematic Analysis: Researchers group similar codes together to identify preliminary themes. These themes represent patterns or concepts that emerge across the data, regardless of the study design. Through iterative analysis and comparison, themes are refined and developed into a coherent framework.
Synthesis: The synthesized themes are analyzed in relation to the research question or objectives of the systematic review. Researchers explore how these themes intersect, diverge, or complement each other across different study designs. This synthesis process enables researchers to generate new insights or interpretations that go beyond individual studies.
Reporting: The findings of the thematic synthesis are reported in the systematic review, typically in the form of a narrative synthesis or thematic map. Researchers describe the key themes identified, supported by evidence from the included studies, and discuss their implications for theory, practice, or further research.
Publication Bias: There may be a bias towards publishing studies with positive findings.
Heterogeneity of Studies: The included studies varied widely in terms of design, participants, and outcomes, making it challenging to compare results directly.
