目的。回顾阿岑的计划行为理论在健康领域的应用，验证该理论对健康相关行为的解释和预测的有效性。大多数材料都取自1985年至今的最新目录(社会科学和行为科学以及临床医学)，以及由此确定的出版物中引用的所有同行评议的文章。结果表明，该理论对意图的解释效果很好，平均R(2)为0.41。对行为的态度和感知的行为控制通常是导致这种可解释的意图变化的重要变量。对行为的预测得出的平均R(2)为0.34。意图仍然是最重要的预测因素，但在所回顾的研究中，有一半的研究显著增加了感知行为控制的预测。模型的效率似乎很好地解释了意图，在与健康相关的行为类别中，感知到的行为控制与态度一样重要。然而，该理论的效率在与健康相关的行为类别中有所不同。
Purpose. To review applications of Ajzen's theory of planned behavior in the domain of health and to verify the efficiency of the theory to explain and predict health-related behaviors.Methods. Most material has been drawn from Current Contents (Social and Behavioral Sciences and Clinical Medicine) from 1985 to date, together with all peer-reviewed articles cited in the publications thus identified.Findings. The results indicated that the theory performs very well for the explanation of intention; an averaged R(2) of .41 was observed. Attitude toward the action and perceived behavioral control were most often the significant variables responsible for this explained variation in intention. The prediction of behavior yielded an averaged R(2) of .34. Intention remained the most important predictor, but in half of the studies reviewed perceived behavioral control significantly added to the prediction.Conclusions. The efficiency of the model seems to be quite good for explaining intention, perceived behavioral control being as important as attitude across health-related behavior categories. The efficiency of the theory, however, varies between health-related behavior categories.
