A mixed model analysis was conducted to assess the impact of condition on salt measurement estimates over time (table 3). There was no significant interaction between condition and time, 65)=1.26, However, there was a significant main F(2, p=.290, η2=0.04. effect for time, 65)= 13.00, with all groups showing a reduction in salt F(1, p=.001, η2=0.17, measurement from pre to post health threat message. There was no significant main effect for intervention, 65)= 0.93, F(2, p=.399, η2=0.03. Salt Intake: Screening to follow-up There was no significant interaction between condition and time, 56.45)=0.44, F(2, p=.645, which regards to dietary salt intake (table 3). There was a significant main effect for η2=0.11, time, 65)= 13.00, with all groups showing a reduction in salt intake F(1, p=.001, η2=0.15, from baseline to follow-up. There was no significant main effect for intervention, 57.9)= F(2, 1.05, Furthermore, there was no association between the salt measurement p=.358, η2=0.05. task pre or post intervention (amount of salt estimated) and self-reported salt intake at 2 weeks. Clinical significance Clinical significant changes in salt intake was assessed by examining the differences in the proportions of participants eating within the government recommended guidelines of salt at 2 week follow up. A larger percentage of participants were eating recommended levels of salt in the self-affirmation condition (23.8%) compared to the self-affirming implementation intention condition (14.3%) and the control condition (11.1%) although no significant effect was observed.
