Thematic analysis is the most common form of analysis in qualitative research . Themes are patterns across data sets that are important to the description of a phenomenon and are associated to a specific research question .

Emerging findings guide sampling to ensure representation of important themes “saturate categories” . Network sampling . Snowball - referrals from earlier participants 42 21 . Interview . Observation . Document analysis . medical charts, patient diaries 43 . External Participation - lowest degree of involvement. Observing situations on television or videotape. Passive Participation - researcher is present but does not interact or participate. Role of a bystander or spectator. Balanced Participation - researcher maintains a balance between being an insider and being an outsider. The researcher observes and participates in some activities, but does not participate fully in all activities. Active Participation - researcher generally does what others do. While beginning with observation to learn the rules, as they are learned the researcher becomes actively engaged in the activities of the setting. Total Participation - researcher is a natural participant. Highest level of involvement and usually comes about when the researcher studies something in which he or she is already a natural participant. 44 22 Level of control Semistructured open interview with six to eight questions/areas Structured, standardised with Unstructured narrative exact, predetermined questions interview with little interference asked in the same order by the interviewer Structured seminstructured unstructured Polit D & Beck C.
