Lay summary
The conventional field assessment of fruit and vegetable (FV) consumption is by self-report. This method is prone to error and large variances rendering it unsuitable as a primary outcome. We propose to undertake an agreement study to ascertain the validity, precision, and acceptability of multiple novel and conventional instruments that measure FV consumption. This study will be conducted with 15 Māori participants, who will undergo two weeks of initial assessment. After a short break (two weeks) undergo assessment (two weeks) whilst receiving an intervention of free FV. This study will provide useful technical information for researchers and clinicians and valued culturally-appropriate instruments for application with Māori and those living in poverty. At the same time, we will be able to guage acceptability of the instruments from a high priority health population group. The feasibility will have impact on engagement with Māori communities and the intended full study on with Māori.
