意图和行为总是相互关联的。尽管这种关系很牢固，但也不是完美的。是什么导致一个人的行为偏离了先前的意图？本研究考察了意向稳定性和不可预见障碍两个因素对意向-行为关系的影响。在一项对101名大学教职员工的纵向研究中，在四年的时间里，更稳定的意图导致了在第四年接种流感疫苗的意图-行为一致性更强。为了调查不可预见的障碍的作用，我们利用了这样一个事实，即在研究的第一年，流感疫苗的供应被推迟，形成了一种障碍，这种障碍出现在疫苗接种意图被测量之后，但在行为可以进行之前。因此，在研究的这一年，意图-行为关系比随后几年没有出现这样的障碍时要弱。这两个结果都有助于解释为什么意图和行为并不总是一致的原因。
Intentions and behavior are consistently correlated to one another. Although this relationship is strong, it is not perfect. What causes a person's behavior to deviate from previous intentions? This study examined the impact of two factors-intention stability and unforeseen barriers-on the intention-behavior relationship. In a longitudinal study of 101 university faculty and staff, more stable intentions over a four-year period led to stronger intention-behavior agreement for influenza vaccination in the fourth year. To investigate the role of unforeseen barriers, we took advantage of the fact that in the first year of the study flu shot availability was delayed, forming a barrier that arose after intentions to vaccinate were measured, but before the behavior could be carried out. As a result, the intention-behavior relationship was weaker in this year of the study than in the following years when no such barrier occurred. Both of these results help to elucidate the reasons why intentions and behaviors are not always aligned.
