However , via the internet questionnaires also present concerns, including the risk that respondents will forego the study due to technical difficulties as well as the potential for difficult to rely on answers.

Questionnaire design influences participant response in several methods: the question type (e. g., dichotomous or perhaps multiple-choice queries, open-ended questions) and the demonstration of the set of questions can affect the consistency and validity of data accumulated.

Ask friends or members of the target audience to complete the questionnaire and evaluate whether they can understand the queries and provide trusted responses.
