Methods of validating questionnaire

There are following types of questionnaires: Computer questionnaire.
Respondents are asked to answer the questionnaire which is sent by mail.
The advantages of the computer questionnaires include their inexpensive price, time-efficiency, and respondents do not feel pressured, therefore can answer when they have time, giving more accurate answers.
