Questionnaire Design

Summary

Treats questionnaire design as where measurement actually happens, walking through planning with the Delphi technique and focus groups, qualitative versus quantitative instruments, and four administration modes including in-person, telephone with random digit dialling, mailed, and internet surveys with their distinctive biases. Develops the four-step cognitive model of survey response and works through open versus closed question formats including checklist, multiple choice, Likert rating, visual analogue, and ranking. Closes with wording rules, structural conventions, pre-testing, response-rate boosters, and validated Canadian instruments such as the PHQ-9, K6, food security module, BC Adolescent Health Survey, and BCCDC behavioural surveillance items.
