Study Notes
Survey Follow-up Procedures and Questionnaire Measures
- The follow-up procedures for surveys involve sending multiple mailings and tracking all correspondence carefully.
- Web-based surveys have different issues including shorter timelines, email address accuracy, and differences in attention to email vs. mail survey invitations.
- It is recommended to avoid conducting surveys during Christmas and summer holiday times, and data collection with reminders typically takes at least 2 months.
- The ability to generalize findings from surveys depends on how the sample is chosen and the response rates, including any non-response bias.
- Good questionnaire measures should be clear, easy to recall, and relevant to the respondents' knowledge or experience, ensuring validity and variability.
- The length of the survey should be tailored to the audience, using simple, unambiguous language and avoiding double-barreled or leading questions.
- Specific reference frames, sensitivity, and explicitness about personal feelings should be considered, while avoiding prestige bias and asking for personal details in a sensitive way.
- Behavior-focused questions are important for measuring what people say they do, and good response options should be accurate, exhaustive, mutually exclusive, and on the same dimension.
- New and existing measures have their advantages and disadvantages, such as the ability to compare data with existing measures but potential limitations in meeting specific needs.
- The two most important aspects of good measures are reliability and construct validity, which involve measuring consistency and ensuring that what is measured aligns with the intended construct.
- Reliability reflects the consistency of measurement across different situations and times, and it is estimated through various methods such as Cronbach's alpha and split halves reliability.
- Good psychometrics, including reliability and validity, are essential for ensuring the quality of survey measures.
Research Methods and Survey Design
- Power calculation is crucial in determining the appropriate sample size for a study, with 80% power being a rule of thumb for detecting relationships.
- Probability sampling allows for generalization from the sample to the population, while non-probability sampling does not.
- Types of probability samples include simple random, systematic, stratified, and cluster sampling, each with specific applications.
- Non-probability sampling methods include convenience, dimensional, purposive, and snowball sampling.
- Cluster sampling is used when a complete list of the population is not available, and random sampling would be too costly.
- Generalizability in research requires considerations of the sampling frame, sample representation, and respondent representation.
- Enhancing survey response rates is critical for increasing generalizability and can be achieved through various survey design and administration strategies.
- Survey design and layout, pretesting, and confidentiality or anonymity play essential roles in survey development.
- Confidentiality in surveys may raise concerns about data usage, while anonymity can encourage honest responses.
- Cover letters for surveys should include specific details about the study, purpose, risks, benefits, privacy, and participant responsibilities.
- Incentives can be used to increase survey response rates and participant engagement.
- It is important to consider the potential benefits and drawbacks of different survey methods and sampling techniques when designing research studies.
