Study Notes

Coding a Questionnaire

During questionnaire creation, consider the data coding process - transferring information from the questionnaire onto a computer for analysis.
Assign a specific value to each response option for variables.
Pre-code the questionnaire by displaying the coding on the instrument itself.
Complex variables requiring open-ended responses, such as profession, can be coded after data collection.

Checklist

Checklists are used for quickly and easily recording data.
They are useful for items that consist of several questions related to a single topic and require the same response format.

Records

Records are numerical data and statistics that institutions, organizations, and individuals keep to track their activities.
Advantages of using records include: being unbiased, covering a long period, and being inexpensive.
Disadvantages include: incomplete records cannot be completed, a lack of certainty regarding data collection conditions, and no guarantee of record accuracy.

Study Design Recap

Determine study aims, background, and rationale.
Identify endpoints or outcome variables, other assessments, and specific variables.
Define how variables are measured and ensure the measurement is sensitive to expected changes.
Assess the reliability and validity of the chosen measures.
Establish clear inclusion and exclusion criteria for study participants.
Create an accrual plan and a timeline for both the overall study and individual participant involvement.
Determine treatments, participant implications, and details on product, dose, quality, administration, and reproducibility of interventions.

Designing an Effective Questionnaire

A cluttered or complex questionnaire will likely deter respondents from completing it.
When creating combined questionnaires, position open-ended questions at the end to increase completion rates.
Place sensitive questions near the end of the questionnaire.
Continuously re-examine and revise questionnaire drafts to optimize their quality.

Pre-testing a Questionnaire

To improve questionnaire quality, it is beneficial to have it reviewed by experts and field-tested.
Conduct a pilot study to pre-test the questionnaire.
Administer the questionnaire to a sample representative of the study population (10-50 people).
Ensure participants know it is a pilot test and collect feedback on length, structure, and wording.
Simulate the conditions of the planned administration (same location, etc.).
Edit the questionnaire based on pilot study results.

Realization of the Pre-test

The pre-test is conducted in two phases:
- Observation phase: Note questions, respondent reactions, duration, and refusals.
- Discussion phase: Gather pre-testers' overall questionnaire assessment, understanding of questions, difficulties encountered, and suggestions for improvement.

Instrument Development

Requires a high degree of research expertise.
Instruments must be reliable (consistent measurement), valid (accurate measurement), and suitable for their function.
Instruments should be free of built-in clues.
Instruments include questionnaires, checklists, and records.

Nine Steps to Developing a Questionnaire

Describe the information required (e.g., dietary behavior, physical activity, food insecurity).
Identify the target participants (e.g., pregnant women, children, older adults).
Select the appropriate research methodology for the target population (e.g., food frequency questionnaire, 24-hour dietary recall, diet history).
Decide on the content of the questions (e.g., nutrient intake, physical activity levels, demographics).
Develop clear and concise question wording, avoiding technical terms, leading questions, and measuring only one thing per question.
Organize questions in a meaningful order and format (e.g., administer in person, via email, or by telephone).
Ensure the questionnaire is concise.
Pre-test the questionnaire to gather feedback and make modifications.
Develop the final survey form.

Main Stages of Data Collection

Obtain permission to proceed, including ethical approval and informed consent.
Collect data following planned logistics and quality control measures to ensure data validity and reliability.
Handle data properly by coding, numbering, and storing it appropriately.

Possible Sources of Bias in Data Collection

Failure to follow sampling procedures as planned.
Measurement bias resulting from:
- Study-induced changes in participant behavior (e.g., elevated blood pressure during measurement).
- Unstandardized equipment.
- Observer bias or variability.
Changes in measurement criteria or recording methods.

Methods of Data Collection

Surveys
Observations
Research Instruments (tools)

Surveys

Non-experimental research method to gather data from a specified group of respondents.
Advantages include: good for descriptive data, can cover various topics, are relatively inexpensive, and can be analyzed using existing software.
Disadvantages include: self-reported data can be biased, may provide a general overview but lack depth, and may not offer adequate contextual information.

Observation

Methods employed to gather firsthand data on programs, processes, or behaviors being studied.
Advantages include: provide direct information on individual and group behavior, allow evaluators to understand the context of a situation, identify unanticipated outcomes, and occur in natural, unstructured, and flexible settings.
Disadvantages include: being expensive and time-consuming, requiring well-qualified observers, potential to affect participant behavior, observer bias, and atypical behaviors potentially being observed.

Research Instruments

Methods for searching for research instruments include: Checking online, examining how the instrument appears and its readability, reviewing scientific publications for similar studies, and consulting books that provide descriptions or copies of instruments.

Questionnaires

Instruments used to collect systematic, standardized information, either numerically or in short answers.
Consist of a series of questions, gathered through oral interviews or written questionnaires.
One of the most commonly used research instruments.

Questionnaire Uses

Collect data from large populations.
Collect identical data at multiple points in time.
Use existing or develop standardized instruments.

Types of Questionnaires

Interviewer-Completed: Interviewers ask questions (in person, telephone) and record responses.
Self-Administered: Respondents receive a survey (mail, email, internet) and complete it independently.

Interviewer-Completed Questionnaires

Advantages:
- Enable complex instruments.
- Limit interviewer bias.
- Reach diverse populations.
- Higher response rates.
- Allow for clarification.
Disadvantages:
- High cost.
- Potential for interviewer bias.
- Subject reluctance.
- Safety concerns.
- Anonymity not guaranteed.
- Scheduling challenges.

Self-Administered Questionnaires

Advantages:
- Low cost.
- Rapid response.
- Valid instructions.
- Respondents can complete at their convenience.
Disadvantages:
- Requires reading ability.
- Less control over data.
- Limited open-ended questions.
- Lower response rates.
- Requires respondent motivation.

Attributes of a Good Questionnaire

Clear and concise language.
Single objective.
One-to-one correspondence to study objectives (each item relates to the topic).
Correct grammar, spelling, and construction.
Avoidance of double-negative questions.
A clearly stated title and purpose.
Assurance of response confidentiality.
Clear directions and a design that facilitates easy data tabulation.

Questionnaire Best Practices

Provide clear and straightforward instructions.
Use simple and logical question formatting.
Pay close attention to layout and spacing.
