Online Surveys (CAWI)

CAWI (Computer-Assisted Web Interviewing) refers to data collection through online questionnaires, using automated logic, filters and randomisation. It is a highly efficient technique for measuring awareness, satisfaction, behaviour, attitudes and segmentation, combining speed, control and consistency.

At QSP, we reinforce quality through rigorous questionnaire design, pilot testing, validation rules and coherence checks, ensuring that online data collection does not compromise methodological rigour.
