  1. Trustworthiness in Qualitative Research Dr. Eti Poncorini Pamungkasari, dr., MPd Public Health Department; Medical Education Unit Faculty of Medicine Universitas Sebelas Maret Surakarta

  2. Validity Does the instrument or measurement strategy actually measure what evaluator purpots to measure?

  3. Reliability The consistency or dependability of the instrument or measurement strategy

  4. Rigour

  5. Rigorous qualitative studies • are more trustworthy and useful • Also attempts to provide information that is related to events

  6. Rigour

  7. Credibility: the confidence that can be placed in the truth of the research findings • Prolonged and varied field experience • Reflexivity (field journal) • Triangulation • Member checking • Peer examination • Interview technique

  8. Transferability: to the degree to which theresults of qualitative research can be transferred toother contexts with other respondents • Purposive sampling • Provide thick description

  9. Dependability: “the stability of findings over time” • Audit trail • A code-recode strategy • Stepwise replication • Triangulation • peer examination or iterator comparisons

  10. Confirmability: the degree to which theresults of an inquiry could be confirmed orcorroborated by other researchers • Audit trial • Reflexive journal • Triangulation

  11. Techniques for ensuring rigour

  12. Theoretical rigour

  13. How to assess theoretical rigour? • Publication (peer review) • Triangulation theory

  14. Methodological or procedural rigour • Qualitative research should provide an explicit account of how the research was conducted by the researcher • Example: how the data was collected and recorded? The method of data coding and analysis?

  15. Interpretative rigour and inter rater reliability • To demonstrated clearly how the interpretation was achieved • Participant feedback • Citation

  16. Evaluative rigour: ethics and politics • Obtaining ethical approval

  17. Prolonged engagement in field or research site: the researcher’s extended time in the field improves the trust of the respondents and provides a greater understanding of participants’ culture and context • Use of peer debriefing: seek support from other professionals willing to provide scholarly guidance, such a members of academic staff, the postgraduate dissertation committee and the department.

  18. Triangulation: the use of multiple methods • Using a combination of methods, researcher, data sources and theories • Allows the research to develop a complex picture of the phenomenon being studies

  19. Types of triangulation

  20. Member check: the analyzed and interpreted data is sent back to the participants for them to evaluate the interpretation made by the inquirer and to suggest changes if they are unhappy with it or because they had been misreported. • An audit trail: an examination of the inquiry process and product to validate the data, whereby a researcher accounts for all the research decisions and activities to show how the data were collected, recorded and analyzed

  21. Stepwise replication: Stepwise replication is a qualitative research data evaluation procedure where two or more researchers analyze the same data separately and compare the results • Code-recode strategy: the researcher codingthe same data twice, giving one or two weeks’ gestation period between each coding. The results from the two codingsare compared to see if the results are the same or different
