A randomized controlled trial of the impact of support visits on self-isolation compliance: The Havering winter/spring support trial.

Objectives: Limited evidence exists on the policies to increase self-isolation compliance, with no experimental evidence. This trial aimed to evaluate the effect of a home visiting intervention in the London Borough of Havering on compliance with self-isolation guidance, relative to positive COVID-19 cases who received no home visits.

Design: Mixed method evaluation involving a two-arm randomized controlled trial (RCT) with an implementation and process evaluation.

Explaining intention to reduce red and processed meat in the UK and Italy using the theory of planned behaviour, meat-eater identity, and the Transtheoretical model.

This study aimed to contribute to the growing literature investigating the psychosocial factors associated with intentions to reduce red and processed meat consumption, given the significant negative impact of meat on public health and in contributing to climate change. A framework combining the Theory of Planned Behaviour with meat-eater identity and the Transtheoretical Model was used to explain intention to reduce red and processed meat consumption across participant samples in the UK and Italy, to identify the factors involved in encouraging behaviour change whilst also considering differences in culinary practices. University students in the UK (n = 320) and Italy (n = 304) completed an online survey including measures from the Theory of Planned Behaviour and the Transtheoretical Model, as well as a measure of meat-eater identity.

Two Birds, One Stone: The Effectiveness of Health and Environmental Messages to Reduce Meat Consumption and Encourage Pro-environmental Behavioral Spillover.

There is a growing consensus that reducing excess meat consumption will be necessary to meet climate change targets, whilst also benefitting people's health. Strategies aimed at encouraging reduced meat consumption also have the potential to promote additional pro-environmental behaviors through behavioral spillover, which can be catalyzed through an increased pro-environmental identity. Based on this, the current study tested the effectiveness of a randomized two-week messaging intervention on reducing red and processed meat consumption and encouraging pro-environmental behavioral spillover.
