Description of intervention(s) / exposure
Eligible participants (parents recruited form an existing database, with a child aged three to 12 years old) completed two scripted telephone interviews conducted by trained research assistants. The first interview was conducted from June to July 2011. Participants reported on a range of demographic and health behaviour data for themselves and a child aged three to 12 years in their household.Where parents had more than one child from age three to 12, the child with the most recent birthday was selected. Following completion of this survey, participants were randomly allocated to one of two groups using a random number function embedded in the computer assisted telephone interviewing software in a 1:1 ratio without stratification. Based on group allocation, participants in this study were posted one of two hypothetical fast food menus. Menus were comprised of items selected from a variety of common fast food outlets in Australia. Generic descriptive names were provided for each food item. Depending on group allocation, participants received: Group 1 (Control). Fast food menu without healthy options. The standard menu contained 26 food and beverage items. Menu items names, description of ingredients and price was listed with each item. Group 2 (Intervention). Menu with the addition of healthier options and energy labelling. Participants in group 2 received the exact same menu as those in group 1, with the addition of 10 healthier food and beverage options. Participants were contacted approximately one to two weeks after receiving these menus and asked a series of questions assessing purchasing intentions and number of times intending to visit a fast food restaurant with the hypothetical menus, for both themselves and their child.

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Parents were recruited via an existing research cohort which had been established as part of a random household Child Health Telephone Survey. A randomly selected sample of parents from this cohort who indicated they were willing to be contacted for future healthy surveys, were telephoned by a research assistant, assessed for eligibility, and those eligible, invited to participate in the study.

Consenting participants were unaware of their group allocation.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Using a random number function embedded within the first telephone interview, consenting participants will be randomly allocated in 1:1 ratio without stratification.
Masking / blinding
Blinded (masking used)
Who is / are masked / blinded?
