Quiz 2: Survey Research
Limitations to Group-administered Surveys
Most populations cannot be sampled in a group setting -Respondents may feel coerced and as a result will be less likely to answer questions honestly
Reliability Measures
Special statistics that help determine whether responses are consistent
Rules for Writing Survey Items: Minimize the Use of Negative Wording
The use of words that negates or indicates the opposite of what was otherwise described
Advantages to Phone Surveys
They can save time and reduce interviewer bias
Rules for Writing Survey Items: Label or Anchor the Rating Scale Points
To clearly indicate what a rating scale means we can use anchors
Questionnaire Development & Assessment: Maintain Focus
A clear conception of the research problem and the population to be sampled is required
Likert Scale
A numeric response scale used to indicate a participant's rating or level of agreement with a question or statement
Restricted Items
A question or statement in a survey that includes a restricted number of answer options to which participants must respond
Versatility
Ability to adapt or be adapted to many different functions or activities -Can be used to enhance understanding of almost any social issue
Anchors
Adjectives given to describe the end points of a rating scale to give the scale greater meaning
Open-ended Items
Allows the respondent to give any response in his or her own words, without restriction -Qualitative research design
Combining Questions into Indices
An index or scale is when several questions are used to measure one concept
Open-ended Items: Researcher Develop Ways to Code Participant Responses
Anticipate and list all possible examples of potential responses in terms of how participants might write or express their responses -Use multiple raters and additional statistical analyses to make sure the coding is accurate
Generalizability
Can be used to develop a representative picture of the attitudes and characteristics of a large population
Group-administered Surveys
Completed by individual respondents assembled in a group
Questionnaire Development & Assessment: Language
Consider translation of surveys to other languages -Differences in language may shape responses
Partially Open-ended Items: Last Open-ended Option
Could be coded further or just analyzed without further coding
Efficiency
Data can be collected from many people at relatively low cost and relatively quickly
Protection of Respondents
Disclose any harmful effect of participation
Rules for Writing Survey Items: Use Neutral or Unbiased Language
Do not use language that is offensive -Responses may be in reaction to the language used
Focus Groups
Guided discussions among potential respondents
Limitations of Electronic Surveys
Hard to get a true representative sample of the U.S. population; households without internet tend to be older, poorer, and less educated than do those that are connected; Much lower rates of survey completion
Advantages to In-person Surveys: Face-to-face Interviews
High response rate and completion rate
Limitation of Mailed/Self-administered Surveys
Higher rates of respondents choosing not to complete and return the survey
Confidentiality
If survey measures attitudes or behaviors that are socially stigmatized, the respondents' rights need to be protected; Only include questions that are important to research; Limit access to information
Phone Surveys
Interviewers questions respondents over the phone and record answers; can in interpersonal or automated -Recommended length of time is between 30-45 minutes
Demographic Questions
Important independent variables necessary for research -Placed at beginning or end of the survey
Partially Open-ended Items
Includes a few restricted answer options and then a last one that allows participants to respond in their own words in case the few restricted options do not fit with the answer they want to give -Researchers can code each answer option as a number
Advantages of Electronic Surveys
Inexpensive and little time commitment from researcher - easy to make online surveys
Reverse Coded Item
Item that is phrased in the semantically opposite direction of most other items in a survey, and is scored by coding or entering responses for the item in reverse order from how they are listed
Rules for Writing Survey Items: Avoid Double-barreled Items
Items that ask participants for one response to two different questions or statements
Rules for Writing Survey Items: Limit the Points on a Rating Scale
Keep the scale between 3 and 10 points
Mailed/Self-administered Surveys
Mailing a questionnaire to respondents who then administer the survey themselves
Maximize Response Rate of Mailed/Self-administered Surveys
Make the questionnaire attractive, make questions clear, minimize open-ended questions, offer incentives, include ways to result the survey, and use follow-up mailings
Questionnaire/Self-report/Survey
Many surveys specifically include questions in which participants report about themselves - their attitudes, opinions, beliefs, activities, emotions, etc.
Pretest the Survey
Obtain feedback on survey by asking others to review it; Administer to small sample; Review responses to each question; Discuss the survey's content with knowledgeable parties; Conduct cognitive interviews
Idiosyncratic Variation
Occurs when individuals' responses vary because of their reactions to particular words or ideas in the question -Single questions prone to this
Anonymity
Only if no identifying information about respondents is obtained is true anonymity provided; Makes follow-up attempts impossible; Allow anonymous responses to a subset of questions
Dichotomous Scales
Only two responses are possible
Response Rate
Percentage of persons surveyed who complete survey
Respondent/Participant
Person who answer questions on a survey
Limitations to Phone Surveys
Reaching sampling units and few people willingly agreeing to complete the survey
Advantage to Mailed/Self-administered Surveys
Relatively inexpensive and requires less time on the part of the researcher
In-person Surveys: Face-to-face Interviews
Researcher can control how long it takes to complete the survey but requires the interviewer to be present for each interview and can be prone to interviewer bias
Cognitive Interviews
Researchers ask test questions, then probe with follow-up questions to learn how questions were interpreted and the meanings of answers
Advantages to Group-administered Surveys
Response rates are typically very high
Bipolar Scales
Scales that have points above and below a zero point -ex: negative 5 to positive 5
Survey
Series of questions or statements, called items, used in a questionnaire or an interview to measure the self-reports or responses or respondents
Interview Schedule
Survey instrument containing the questions asked by the interviewer in an in-person or phone survey
Questionnaire
Survey instrument; The questions for a self-administered survey
Electronic Surveys
Survey is sent and administered by computer, either email or on the Web
Advantage of Restricted Items
Survey responses can be easily entered or coded for statistical analysis
Rules for Writing Survey Items: Avoid the Response Set Pitfalls
Tendency for participants to respond the same way to all items in a survey when the direction of ratings is the same for all items in the survey
Limitations to In-person Surveys: Face-to-face Interviews
Tendency for the demeanor, words, or expressions of a researcher to influence the responses of a participant when the researcher and the participants are in direct contact
Limitation of Restricted Items
The analyses is restricted to the finite number of options provided to participants
Item Response Rate
The percentage of items that are completed on a survey
Cautions of Combining Questions into Indices
The presupposition that each component question is indeed measuring the same concept may be mistaken; Combining responses to specific questions can obscure important differences in meaning among the questions; Questions may cluster together in subsets; Particular questions weighted more than others in the calculation of the index
Questionnaire Development & Assessment: Build on Existing Instruments
Use already designed survey questions to measure key concepts in present study
Rules for Writing Survey Items: Use Rating Scales Consistently
Use only one rating scale at a time -Use only one scale if possible
Rules for Writing Survey Items: Keep it Simple
Use simple words or language in a survey
Use of Survey
Used to quantify, describe or characterize an individual or group
Rules for Writing Survey Items: Minimize item and survey length
Write the survey to be as short and concise as possible, yet still able to convey what is intended to measure -Key goal is to minimize how long it takes, which does not always mean that the number or items in the survey must be small
