7.0 Qualitative - data collection Flashcards
Methods of collecting data in qualitative study
Observation (active observer or passive observer)
Interview
Focus group discussion
Open ended questionnaire
Journaling
Using available information
Using available information and five major types
Usually there is a large amount of data that has already been collected by others, although it may not
necessarily have been analysed or published.
Locating these sources and retrieving the information is a good starting point in any data collection effort.
Five major types
1. Archival documents
2. Journals
3. Maps
4. Videotapes and audiotapes
5. Key informants
Key informants could be knowledgeable community leaders or health staff at various levels or informative members of the target group. They can be involved in various stages of the research, from the statement of the problem to analysis of the data and development of recommendations.
What is observation?
Observation – ‘’the process of collecting data by looking rather than listening.”
“Observation of behaviours, actions, activities and interactions is a tool for understanding more than what people say about (complex) situations, and can help to understand these complex situations more fully.”
Observation- Types
Nonparticipant observation – unobtrusive.
OR
Participative – researcher participates in the setting (can be acknowledged and overt; or concealed or covert)
OR
Structured (quantitative) – collecting of data according to a set of predefined rules and procedures (with a checklist, categories to check, rating scales) . [Looking for]
OR
Unstructured (qualitative)– general idea of what will be observed, but takes a holistic, unstructured and unfocused approach, recording events as they occur. [Looking at]
Note:
- These approaches often overlap (using structured coding forms for routine data alongside unstructured field notes and narratives).
- Observing what does not happen may be as important as observing what does happen.
When is inter-observer reliability required?
Unstructured observation -
Interobserver reliability required where there are 2 or more researchers - need to ensure they are consistent.
Steps in planning for observation
Observation must be conducted in a SYSTEMATIC manner.
Determine WHO/WHAT will be observed.
Determine ASPECTS that will be observed (characteristics, attributes, behaviors, etc.).
Determine WHERE and WHEN observations will be made.
DEVELOP the observation RECORD SHEET.
PILOT TEST the observation record sheet. Train the observers and have them practice. COLLECT the information.
ANALYSE and INTERPRET the collected information. Write up and use your findings.
Observations need to be RECORDED to be credible: Observation guide, Recording sheet, Checklist, Field note, Picture, Combination
What are some of the limitations of observation?
- Only observing so miss the full picture
- Inconsistencies between researchers observing
- Bias in relation to the interpretation of observations
What are the advantages (4) and disadvantages (6) of observation?
Advantages
-Most direct measure of behaviour
-Provides direct information
-Easy to complete, saves time
-Can be used in natural or experimental settings. Can see things in their natural context
- Unobtrusive, least intrusive
- Can see things that may escape conscious awareness, things that are not seen by others
- Can discover things no one else has ever really paid attention to, things that are taken for granted
- Can learn about things people may be unwilling to talk about Inconspicuous – least potential for generating observer effects
- Can be totally creative – has flexibility to yield insight into new realities or new ways of looking at old realities
Disadvantages
-May require training
-Observer’s presence may create artificial situation
-Potential for bias
-Potential to overlook meaningful aspects
-Potential for misinterpretation
-Difficult to analyse
How can the reliability of observational research be enhanced?
- Record for reliability
- Structured tool
- Interobserver reliability when 2 or more researchers using unstructured ob
What are the ethical implications of undisclosed (covert) participant observation?
How can the observer attempt to gain access to the social situations of interest?
Is observation culturally appropriate?
Interviewing
A conversational practice where knowledge is produced through the interaction between an interviewer and an interviewee or a group of interviewees
Talking and listening to people.
Verbally asking program participants the program evaluation questions.
hearing the participant’s point of view in his or her own words.
Interviews can be either structured or unstructured, in person or over the telephone.
Done face-to-face or over the phone
Individual or group (i.e. a focus group)
Types of interviews
Structured interviews – standardised questions (questionnaire approach; non conversational; may also have a few open ended questions; responses are consistent, enhancing reliability).
Semi-structured interviews - uses an interview guide; used for shorter interviews (common approach in qualitative research).
Unstructured interviews – often used alongside observation in qualitative research; focus on particular topic and techniques to steer the interview.
In-depth interview – an extensive form of interview.
Interviews are useful when… (4)
When the subject is sensitive
When people are likely to be inhibited in speaking about the topic in front of others
When people have a low reading ability
When bringing a group of people together is difficult (e.g., in rural areas)
