Lincoln and Guba's Evaluative Criteria
Lincoln and Guba posit that trustworthiness of a research study is important to evaluating its worth. Trustworthiness involves establishing:
- Credibility - confidence in the 'truth' of the findings
- Transferability - showing that the findings have applicablity in other contexts
- Dependability - showing that the findings are consistent and could be repeated
- Confirmability - a degree of neutraility or the extent to which the findings of a study are shaped by the respondents and not researcher bias, motivation, or interest.
Lincoln and Guba describe a series of techniques that can be used to conduct qualitative research that achieves the criteria they outline.

- Prolonged Engagement
- Persistent Observation
- Peer debriefing
- Negative case analysis
- Referential adequacy
