This study is a longitudinal controlled trial that is designed to investigate the effectiveness of a multi-component intervention on improving fruit and vegetable consumption in teenagers and their mothers. Participants will be allocated in three groups with a) an intervention group in which mothers and children receive the intervention and questionnaires, b) only the children receive the intervention and mothers and children receive the questionnaires, and c) mothers and children are in active control group and only receive the questionnaires. The intervention package contains behavior change techniques targeting outcome expectancy, self-efficacy, action planning, coping planning, and self-monitoring. The active control group receives an information sheet regarding recommendations on fruit and vegetable intake. There will be 3 assessment points in time, with 1 months in between. All the intervention materials and information sheets will be handed to participants after the baseline assessment. The self-monitoring calendar will be collected at time 2 assessment.
