Parents' Perceptions and Responses to the UK Soft Drinks Industry Levy.

To record parents' awareness of the UK soft drinks industry levy (SDIL) and explore associations between negative psychological reactance to the levy and motivation and intentions to change consumption and purchasing.A cross-sectional online survey with UK-based parents of children aged 5-11 years (n = 237). Regression analyses were used to test associations between psychosocial responses to the levy and behavioral intentions to change family consumption and purchasing.A total of 92% of responding parents were aware of the SDIL. Of the responding parents, 57% supported its aims, but 29% felt it threatened their freedom of choice. A total of 41% expressed intention to change shopping habits or restrict their child's intake as a result. Reactance and motivation were poorer in low-income families, and intentions to change were positively predicted by motivation.This snapshot suggests that the UK SDIL is largely supported by parents and associated with intentions to change their children's intake.
