Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Current primary outcome measures as of 27/07/2011: Data on demographic characteristics, key study outcomes and mediators will be collected pre- and immediately post-intervention, and at 6-month follow-up. 1. Demographics: 1.1. Age 1.2. Family structure (marital/cohabitation status, number and ages of dependent children, other household members) 1.3. Education level 1.4. Own and household income will be assessed 2. Outcome measures: Data on food purchasing will be gathered using a combination of electronic sales data, which Coles have confirmed they will provide to us via linkage with their store loyalty cards (FlyBuys); and self-report survey data (to assess consumption and complement the electronic sales data). We will use previously-published measures of both fruit and vegetable purchasing and consumption. Measures of daily equivalent fruit and vegetable purchasing quantities (adjusted for household members/composition) and daily equivalent serves consumed will be calculated. Previous primary outcome measures from update on 30/06/2010: Data on demographic characteristics, key study outcomes and mediators will be collected pre- and immediately post-intervention, and at 6-month follow-up. 1.

Secondary
| Measure | Time frame |
|---|---|
| Current secondary outcome measures as of 27/07/2011: 1. Mediator measures: We will assess self-efficacy, perceived barriers and perceived affordability via validated self-report surveys. 2. Process evaluation outcomes: We will assess subjective perceptions of the intervention components that may be useful in predicting outcomes at the completion of the intervention. 3. Economic evaluation: A cost consequences analysis will be conducted from a societal perspective comparing incremental costs and outcomes in the intervention arm to the control arm at 12 months. Intervention resource use and costs will be prospectively recorded via project team records and Coles data, supported by interviews with the project team. Household cost impact will be determined through external (Coles) data on food purchasing combined with participant self-report data on non-Coles and Coles-non-Flybuys food purchasing over the course of the intervention and follow-up period. Previous secondary outcome measures from update on 30/06/2010: 1. Mediator measures: We will assess self-efficacy, perceived barriers and perceived affordability via validated self-report surveys. 2. Process evaluation outcomes: We will assess subjective perceptions of the intervention components that may be useful in predicting outcomes at the completion of the intervention. | — |
