title: Attitudes and intentions toward purchasing novel foods enriched with omega-3 fatty acids.
abstract: OBJECTIVE
  To identify the nature, strength, and relative importance of influences on intentions to consume foods that are enriched with omega-3 fatty acids using the Theory of Planned Behavior (TPB).
  
  
  METHODS
  A cross-sectional self-administered questionnaire.
  
  
  METHODS
  Community-based residents living in the Illawarra region of New South Wales, Australia.
  
  
  METHODS
  Two subsamples were surveyed via questionnaire: community members who responded to a local media advertisement (n = 79), and subjects in a dietary intervention trial for type 2 diabetes mellitus (n = 50).
  
  
  METHODS
  Using the TPB variables-intention, attitude, subjective norm, and perceived behavioral control-questionnaire items were constructed to measure intention to consume omega-3-enriched novel foods.
  
  
  METHODS
  The results from subsamples did not differ and were combined for analysis. The determinants of intention defined in the TPB were investigated using multiple linear regressions.
  
  
  RESULTS
  Regression analysis showed that the model was a significant determinant of intention (R2 = .725; P < .001). Attitude was a significant determinant of intention, whereas subjective norms and control beliefs were not.
  
  
  CONCLUSIONS
  With attitude having the greatest influence on intentions, immediate prospects for modifying behavior are likely to come through a change in attitude, specifically in beliefs about the effectiveness of enriched products in achieving specific health benefits.
  
  
  CONCLUSIONS
  Promoters of omega-3-enriched foods would be advised to direct their promotions toward changing the attitudes of consumers about the effectiveness of the functional ingredient.
