OBJECTIVE: The present study sought to test the efficacy of a brief research-based, leaflet-like intervention to promote eating the recommended daily intake of fruit and vegetables (RDIFV). DESIGN: A controlled, pre- post-test experimental study with random allocation and a 1 week self-report behavioural follow-up was conducted. METHOD: The intervention employed persuasive communication targeting self-efficacy and intention, and invited participants to form implementation intentions in relation to acquiring and preparing fruit and vegetables for consumption. RESULTS: Intervention participants had stronger post-intervention intentions to consume the RDIFV, and higher anticipated regret in relation to failing to do so, compared with controls, controlling for pre-intervention scores. At follow-up, the intervention group was found to have eaten more fruit and vegetables and to have consumed the RDIFV more frequently. DISCUSSION: It is concluded that this study supports the previously reported power of implementation intentions to prompt enactment of intentions, and that a brief research-based leaflet-like intervention could result in immediate enhancement of intentions and anticipated regret, and promote greater fruit and vegetable consumption.
