摘要：
The additive and interactive effects of habit strength in the explanation of saturated fat intake were explored within the framework of the Theory of Planned Behaviour (TPB). Cross-sectional data were gathered in a Dutch adult sample (n = 764) using self-administered questionnaires and analyzed using hierarchical regression analyses and simple slope analyses. Results showed that habit strength was a significant correlate of fat intake (beta = -0.11) and significantly increased the amount of explained variance in fat intake (R2-change = 0.01). Furthermore, based on a significant interaction effect (beta = 0.11), simple slope analyses revealed that intention was a significant correlate of fat intake for low levels (beta= -0.29) and medium levels (beta = -0.19) of habit strength, but a weaker and non-significant correlate for high levels (beta = -0.07) of habit strength. Higher habit strength may thus make limiting fat intake a non-intentional behaviour. Implications for information and motivation-based interventions are discussed. (c) 2008 Elsevier Ltd.
