Q

whats a high vs low response rate

A
  • A high response rate indicates there is a less chance of significant response bias than a low response rate.
  • A low response rate is a danger signal, because the non respondents are likely to differ from the respondents in ways other than just their willingness to participate in the survey.

Q

whats dense sitting and floating

A
  • Two related problems in question writing also stem from people’s desire to choose an acceptable answer.
  • There is no uniformly correct solution to these problems
  • Fence-sitters, people who see themselves as being neutral, may skew the results if you force them to choose between opposites.

Q

whats transferability

A

: evaluates if findings can be applied to other people, groups, contexts. Described participants and setting of study eg type of spinal cord injury, where they still in rehab or in community

26
Q

whats dependability

A

description of research process. What type of data analysis was used, how did they analyse data, why have they chosen to do one or two data collection, clear decisions around sampling process. Strategy: audit trail

27
Q

whats confirmability

A

role of research in research process, have they stated values, beliefs, perspectives that caused them to lead the study.

28
Q

strategies of trustworthiness in qual

A 
audit trial
triangulation
member checking 
peer review/debieging
thick description
reflexivity
prolong engagement 
feild notes
29
Q

whats audit trial

A

involves an external person that checks on research descions that have been made. Important to outline decisions made throughout research. Keep a methological log, discus why chosen techniques.

30
Q

whats triangulation

A

multiple methods of data collect (interviews, observation), multiple data sources (multiple participants in different setting compare), researchers different backgrounds brings different perspectives

31
Q

whats member checking

A

v: supports confirmability and credibility, checking interpretations of data with participants. Could transcribe interview and send to participants, or write a summary and send to participant

32
Q

what reflexivity

A

: researcher reflecting on process gone through, interest of starting study, professional background, assumptions or concepts coming into study with. Supports credibility.

33
Q

types of survey research

A
  1. Self-completion questionnaire
  2. Interviewer administered survey
  3. Telephone interview survey
  4. Mail / Postal survey
  5. Group administered surveys
  6. Web-based survey
34
Q

whats a self completion questionnaire

A

Are completed in writing by the respondent.

  • Most common mode of completion is delivery & return through the mail.
  • Can also be completed in the presence of the researcher (who can provide assistance and check questionnaire for completeness).
  • Offer low cost relative to other types of surveys (cost of postage & printing).
  • Potential coverage of a widely dispersed population (e.g., throughout Melbourne).
  • Avoids potential for interviewer bias.
  • Has the potential for low response rates.
  • Requires a certain literacy level for respondents to complete survey.
  • Are well suited for less complex topics.
  • Should be shorter than an interview and use more close-ended questions (e.g., true/false, yes/no, agree/disagree).
35
Q

whats interviewer administers survey

A
  • Each respondent is asked the same set of questions by the interviewer.
  • Able to collect more detailed and complex data.
  • Open ended questions can be used more readily.
  • Are costly and resourceintensive.
  • Are able to deal with more sensitive or personal topics.
  • Are more suitable if you are trying to elicit the respondent’s story or personal narrative about a topic.
  • Interviewers need to travel to respondents.
  • Interviewers need to be trained to ensure consistency in how questionnaires are administered, scored and interpreted.
  • Personal characteristics (such as age, gender, ethnicity) of interviewer can impact on the response rate & nature of the responses.
36
Q

whats telephone interview survey

A
  • Maximise the advantages of the self-report questionnaires and face-toface interviews using this approach.
  • Since travel is not required, can cover a large population relatively quickly at a lower cost.
  • Researcher can provide clarification on unclear questions if needed
  • Response rates while not as high as face-to-face interviews, can be between 90 to 95% although this is dependent on the topic and level of interest of the respondents.
  • Considered suitable for complex tasks.
  • Can deal with more sensitive topics
37
Q

disadvantages of telephone interview surveys

A
  • Time consuming to complete
  • Need access to telephone numbers (e.g. unlisted numbers & cell phone numbers)
  • Need trained interviewers
  • Have over-abundance of telemarketers
  • Issues of sampling bias & generalisability of findings.
  • May be not suitable for certain groups such as people with hearing impairment, older people, people with cognitive impairment, lower income who may not have a phone and recent migrants whose first language is not English
38
Q

advantages of mail/postal survey

A
  • Efficient for volume of information
  • People are likely to provide frank, thoughtful, honest information that is tension free
  • Gives people adequate time to respond to questions
  • All respondents receive exactly the same questions in the same way…ensures some degree of consistent
  • Allows for larger samples to be recruited
  • Cheaper to conduct than interviews
  • Respondent does survey on his/her own time
39
Q

disadvantages of mail/postal survey

A
  • Low response rate
  • Must be simple and easy to understand
  • Need accurate mailing lists with addresses
  • Mailing / postage and copying costs
  • Privacy, confidentiality, and anonymity must be assured
  • Results may be misleading if do not follow-up with non respondents
  • Generalisability may be limited if respondents are self selected
  • Respondents’ handwritten responses may not be legible
40
Q

advantages of group administered surveys

A
  • High response rate
  • Easy to clarify items for all respondents
  • Provides greatest sense of respondent anonymity
  • Inexpensive
41
Q

disadvantages of group administered survey

A
  • May require cooperation of others (e.g., to access groups)
  • Reach only those in attendance
  • Group dynamics may influence individual responses
  • Opportunity for researcher to potentially influence participants’ responses or answering of items
42
Q

web based survey advantages

A
  • Nearly complete elimination of paper, postage, mail out and data entry costs
  • Time for implementation of survey can be reduced
  • Once electronic data collection system is developed, cost of surveying additional respondents is much less
  • Display of response data can be simultaneous with completion of surveys
  • Reminders and follow-ups for non-respondents is relatively easy
  • There are currently several good quality online systems for developing, formatting and administering online surveys include Survey Monkey and Qualtrics
43
Q

disadvantages of web based survey

A
  • Not everyone is connected to the web
  • Surveys may not be conducive to be completed on certain mobile devices
  • Not all respondents are equally computer literate
  • Sampling of email addresses can be difficult
  • The decision not to respond is likely to be made more quickly
44
Q

sampling methods

A 
random smapling
convince smapling 
snowball sampling
quota sampling
proportional sampling
45
Q

whats random sampling

A

is the method of choice  a precise selection method where all individuals in a defined population have an equal chance of being selected for inclusion in the study

46
Q

whats convenience sampling

A

is based on these participants who are available when data gathering is scheduled to occur.

  • This method of sampling is open to bias & subjectivity.
  • Another method is volunteer sampling where individuals volunteer to take part and are therefore self-selected
47
Q

whats snowball sampling

A

one member of the sample is asked to suggest other people who could be involved in the study.

48
Q

whats quota sampling

A

different groups need to be represented in proportion to their size within the overall populations.

49
Q

sample size

A
  • Too small a sample is unlikely to give an accurate description of the issue being explored; results can be biased.
  • As a rule, aim for as large a sample as time, availability of participants and funding permits.
50
Q

different research designs quant

A

Types of research designs:

  1. Experimental & Quasi-experimental
  2. Single subject studies
  3. Field studies & naturalistic observations
  4. SURVEY STUDIES (focus of OCC3041)
  5. Psychometric studies
51
Q

experimental research

A
  • Basic characteristic is that the investigator manipulates an independent variable that is expected to produce an effect on the dependent variable
  • Design is meant to provide evidence that the independent variable is the cause of the changes or differences in the dependent variable
  • Main aim is to control as much as possible the extraneous influences that might lead to an incorrect conclusion about the influence of the independent variable on the dependent variable.
52
Q

quasi experimental

A
  • Lacks the same degree of rigour found in true experiments (e.g., single group or whereby participants act as their own control group) or convience sampling
  • Less costly, most common research design conducted by OT’s
53
Q

single subject studies

A
  • Examine the impact of interventions on single subjects who serve as their own controls.
  • Often involves gathering baseline data and then gathering data during alternating periods in which the experimental condition is present or withdrawn (e.g., ABABA design).
  • EXAMPLE: sensory processing presented with children with autism. Child assessed pre-test thorough out treatment and post-test. Childs performance is compared to their previous results.
54
Q

field studies and naturalistic observations

A
  • Takes place in actual, real-life settings.
  • Researchers study events as they happen and persons in their natural environments.
  • Largely used in qualitative research contexts
55
Q

survey studies

A
  • Are non-experimental designs undertaken to investigate the characteristics of a defined group or population.
  • Often conducted with large samples. More than 100
  • Will use mailed surveys, webbased questionnaires, face-toface interviews, phone interviews or group administered survey
56
Q

research purposes types

A
  1. basic: - Includes investigations undertaken for the purposes of generating evidence about some phenomena or testing theory about some phenomena.
  2. applied: - Involves studies that seek to solve some practical problem or to generate information specifically to inform practice
  3. transformative: - Studies designed to bring about change in some practical situation or specific context.
57
Q

purpose of research

A
  • Description.
  • Analysis of relationships.
  • Analysis of differences.
  • Analysis of association / correlation.
  • Predictiveness of variables.
58
Q

timing of research

A

Retrospective: the researcher uses data collected before the research question was formulated.
Prospective: the researcher completes data collection after the research question was developed.

59
Q

levels of manipulation

A

Experimental research: involves controlled manipulation of participants. • Non-experimental: does not involve the manipulation of participants

60
Q

types of controls applied to variables

A
  • Control of implementation of independent variable.
  • Control of participant selection & assignment.
  • Control of extraneous variables related to setting.
  • Control of extraneous variables related to the participants.
  • Control of measurement of the dependent variable.
  • Control of information given to participants and research.
