Q

5 criteria for trustworthiness

A

Credibility: confidence in the “truth” of the data and its interpretations

Dependability: reliability of data over time and conditions

Confirmability: data represent the information participants provided, interpretation is sound

Transferability: extent to which findings can be transferred to other settings/groups

Authenticity: fairly shows a range of realities; reader develops heightened sensitivity

Q

Phenomenology

A

To describe experience as it is lived; the essence of an experience
The focus is on writing in such a way that the essence of an experience is revealed
A process of reading, reflecting and writing
The writing is often evocative, poetic and is used to evoke understanding

Q

Ethology:

Ecologic psychology:

Ethnomethodology:

Symbolic Interaction:

Discourse analysis:

A

Ethology: study of human behavior as it evolves (Lord of the Flies)

Ecologic psychology: influence of environment on human behavior (Lost)

Ethnomethodology: how people make sense of their everyday activities

Symbolic Interaction: how people make sense of social interactions and interpretations attached to social symbols (hashtags?)

Discourse analysis: rules, mechanisms and structure of conversation/text

Q

Ethnography

A

Focuses on describing culture or the “cultural scene” (culture can be small group culture too)
Ethnographic work is always contextual
There are many types of ethnography (classical, systematic, interpretive, critical, focused etc….)
Key elements of ethnography:
fieldwork (participant observation; immersion in the field), focus on culture (norms, values, beliefs, practices, rules)

Q

Grounded Theory

A

Explores social or psychological processes/method for the study of phenomena

conceptualization is key for the main concern or problem

Based on symbolic interactionist approach (people behave based on ways they interpret symbols and experiences)
Builds a theory about a process
Uses inductive and deductive approaches
Constant comparative analysis
Theoretical sampling
“What is the process of adjustment following heart attack?”

Q

Participatory Action Research

A

Action Research
Lewin: production of knowledge can be political and used to exert power
PAR researchers work with vulnerable groups
Collaborate to identify areas of research
Use knowledge (findings) to empower

Q

theories

models

framework

A

 Theories
 Abstract generalization that offers a systematic
explanation of something
 E.g., theory of planned behaviour, health belief
theory, stress and coping theory

 Models
 Less formal – haven’t identified relationships
fully (yet)

 Frameworks
 Overall conceptual underpinnings of study
 Theoretical framework
 Conceptual framework

questions

 Phenomenology: meaning
questions

 Ethnography: cultural description
questions

17
Q

Directional hypothesis

Nondirectional hypothesis

A

Directional hypothesis
Predicts the direction of a relationship

Nondirectional hypothesis
Predicts the existence of a relationship, not its
direction

18
Q

Research hypothesis

Statistical or null hypothesis

A

Research hypothesis
States the actual prediction of a relationship

Statistical or null hypothesis
Expresses the absence of

19
Q

3 Ethical Principles

A

Respect for Persons
Informed consent
autonomy

Concern for Welfare
Risks and benefits

Justice
Offered to all
No imbalance of power

20
Q

5 components of consents

A
 Disclosure
 Understanding
 Voluntariness
 Competence
 Consent
21
Q

3 hallmark of experimental design

A

manipulation

control group

randomization

22
Q

Quasi-experimental Study Design

A

 Many different designs
 No randomization
 Often no control group

23
Q

eg of non experimental study

A

observational - case study, cohort

descriptive - correlational

24
Q

cohort study

A

observational, follow up studies

usually prospective, looking at disease

25
Q

case study

A

observational, looking at history and data history

case study design - usually retrospective

26
Q

non probability sampling

A

Convenience
Snowball: Potential for bias because of location/access
Quota: Identify strata and determine how many participants from each stratum.
Consecutive: Every person during a specific time frame
Purposive: Choose participants based on characteristics that reflect theoretical foundations of study

Strengths and Weaknesses of non-probability sampling
Convenient and less expensive
Rarely representative, will likely miss out on some members
Emphasis on internal vs. external study validity

27
Q

probabiblity sampling

A

Simple random: Create a sampling ‘frame’ (list with numbers assigned to each potential ‘recruit’); Pick random numbers from frame
Stratified random: Enhances representativeness by ensuring that there is a sample from each identified strata
Cluster: Random sample of clusters then random sample of individuals
Systematic: Every “kth” person

Strengths and Weaknesses of Probability Sampling
Stronger than nonprobability sampling
Expensive, may not be practical
May be too narrow – “My patients are the ones where were excluded from the RCT”
