This study explored whether the effects of implementation intentions on increasing fruit and vegetable intake were moderated by dietary restraint. In total, 208 participants were randomly allocated to control or implementation intention conditions where they were asked to write down when, where and how they would increase their fruit and vegetable intake. Implementation intentions increased fruit and vegetable intake but only in participants scoring low (not high) on rigid dietary restraint. Motives underlying fruit and vegetable consumption may be different for restrained and unrestrained eaters. Efforts to increase their intake may need to be tailored, for example, through motivational rather than situational cues.
本研究探讨了实施意向对增加水果和蔬菜摄入量的影响是否受到饮食抑制的调节。共有 208 名参与者被随机分配到对照组或实施意向组，要求他们写下何时、何地以及如何增加水果和蔬菜的摄入量。实施意向确实增加了水果和蔬菜的摄入量，但仅在饮食抑制评分低（而非高）的参与者中如此。受饮食抑制和不受饮食抑制的人可能有不同的水果和蔬菜消费动机。可能需要针对他们的摄入量进行个性化干预，例如通过激励而不是情境线索。
