Questionnaire design and validation
Our Questionnaire Design and Validation service is tailored to assist researchers in developing reliable and valid questionnaires for their studies. This includes guidance on item generation, scale development, and pilot testing, as well as comprehensive validation processes to ensure the instrument’s reliability and validity. Our objective is to provide researchers with robust tools for data collection that meet the highest standards of scientific rigor.
Package Includes:
- 45-minute meeting/design/validation:1500 SAR
- Service without validation: 1000 SAR
Validation Process:
Internal Validity:
- Internal validity refers to the extent to which the questionnaire accurately measures the intended constructs within the study. We use statistical tests such as Cronbach’s alpha to assess the internal consistency of the questionnaire.
External Validity:
- External validity refers to the extent to which the results of the questionnaire can be generalized to other settings or populations. We ensure external validity through thorough pilot testing and feedback from a representative sample of the target population.
Validity Tests:
- Cronbach’s Alpha: Used to measure internal consistency and reliability.
- Factor Analysis: Used to assess the construct validity and ensure that the questionnaire items cluster together in a meaningful way.
- Content Validity Index (CVI): Used to evaluate the relevance and clarity of each item based on expert feedback.
Questionnaire Design Platforms:
- We utilize various platforms for questionnaire design, including Google Forms, REDCap, and SurveyMonkey, based on the specific needs and preferences of the client.
