Secondary | Perceptions of peers' ideal portion sizes | Questionnaire measuring participants' perceptions of their peers' ideal portion sizes. Participants were provided with images of different energy dense foods. For each image, judgements were made on whether the portion was 'too little', 'slightly less than I would eat', 'just right', 'slightly more than I would eat', or 'too much'. The aim of the intervention was to reduce the ideal portion size. | Baseline at the beginning of week 1 and intervention end at the end of week 4 | |
