Presence of a Behaviour Change Technique in an intervention arm is indicated by an X.
¹Effect size from most effective (greatest increase in alternative, more active travel modes) through to least effective (decreases in active travel modes), where the effect size could be calculated.
²1: Provide information on consequences of behaviour in general; 2: Provide information on consequences of behaviour to the individual; 5: Goal setting (behaviour); 7: Action planning; 8: Barrier identification/problem solving, 12: Prompt rewards contingent on effort or progress towards behaviour; 13: Provide rewards contingent on successful behaviour; 15: Prompting generalisation of a target behaviour; 16: Prompt self-monitoring of behaviour, 20: Provide information on where and when to perform the behaviour; 21: Provide instruction on how to perform the behaviour; 28: Facilitate social comparison; 40: Stimulate anticipation of future rewards.
