- questionnaire are standardised, they are easy to replicate to check reliability
- WEAKNESS
- Misunderstandings of questions or not find the answer they would like to tick due to the use of forced choice closed questions.
- Biased samples - questionnaire are suitable for Ps who are willing and able to spend time completing them. These people are not representative of the general population.
- Low response rate - they aren’t efficient
- closed questions are not suitable for sensitive issues requiring detailed understanding
- Ps may not be honest in order to give answers expected of them or to show themselves in the best possible light (social desirability bias)
