*researcher-participant relationship

The researcher’s personality is a key factor in qualitative research. Skills in empathy and intuition are cultivated; the researcher must become closely involved in the participant’s experience to interpret the data. It is necessary for researchers to be open to the perceptions of the participants, rather than to attach their own meaning to the experience.

  • Maintain an open mind; remove biases; submit results to participants to accurately capture their perception

What are keywords.

Chapter 6

A

You can narrow the number of articles and retrieve fewer but relevant articles by using keywords to search. Keywords are terms that serve as labels for publications on a topic.

For example, a quasi-experimental study focused on providing text message reminders to patients living with heart failure who are taking five
or more medications might be found by searching for keywords, such as electronic communication,
instant messaging, medication adherence, patient teaching, quasi-experimental designs, and heart
failure.

Definition: A review of literature is the process of finding relevant research reports and theoretical sources, critically appraising these sources, synthesizing the results, and developing an accurate and complete reference list.

Purpose: Identifies the current knowledge of a practice problem (2) Identifies what is Known about the topic (Identifying the gaps in this knowledge base (3) Explaining how the study being reported has contributed to building knowledge in this area.
