Compilation on theories related to designing questionnaires.

All I need is some theories related to writing questionnaires, i.e. theories related to different types of questions on questionnaires. The questionnaire is for a Masters dissertation on the accreditation process for language schools in the UK, so I would like some of the quotes to be from ELT journals related to accreditation. Please also use other sources for theories, such as Denscombe, etc.

Please note this is not an essay request, but more a compilation of theories related to designing/writing questionnaires.

should the writer not understand what I need, please have him contact me to avoid any confusion and therefore a final product that may be wrong. Thank you.
