Dietary questionnaires


Updated version available, please click here for more information 


The Dietary Questionnaire for Epidemiological Studies Version 2 (DQES v2) is a modification of a food frequency questionnaire (FFQ) that was developed by Cancer Council Victoria in the late 1980s to measure dietary intake of people taking part in the Melbourne Collaborative Cohort Study (MCCS). These were men and women, recruited for the study between 1990 and 1994, who at the time of recruitment were 40-69 years of age and resided in Melbourne, Victoria. The majority were born in Australia, Greece or Italy.

The DQES v2 covers five types of dietary intake, incorporating 80 items:

  1. cereal foods, sweets and snacks
  2. dairy products, meats and fish
  3. fruit
  4. vegetables
  5. alcoholic beverages

DQES v2 format

DQES v2 is available in both electronic (online) and hardcopy (printed) formats.


The electronic version of DQES v2 provides a more economical option; as the collection of electronic data and its analysis can be performed more efficiently than with paper based systems.  This difference is reflected in the lower unit price for electronic DQES v2.  Electronic DQES v2 is completed online through a secure server. The online questionnaire takes participants about 5 minutes to complete.


For those participants for whom online completion is not feasible, a printed version of DQES v2 is also available. Printed questionnaires are posted to the Institution and competed questionnaires are to be returned to Cancer Council Victoria for analysis.
