Twenty-nine male and female adults with asthma were tested to determine the relationship between perceived response to emotional triggers of asthma and bronchoconstrictive suggestion. Subjects were told that they were inhaling a bronchoconstricting agent in four increasingly potent concentrations, when in fact the solution the subjects inhaled was nebulized isotonic saline. Ten subjects responded to suggestion with a greater than 20% increase in specific airway resistance, but this response could not be predicted by the report of perceived emotional triggers of asthma. The finding that perception of asthmatic response to emotional arousal does not predict airway response to bronchoconstrictive suggestion may mean that suggestion is an invalid proxy variable for studying the role of psychological factors in provocation of asthma.
对29名患有哮喘的成年男女进行了测试，以确定哮喘对情绪触发因素的感知反应与支气管收缩暗示之间的关系。受试者被告知他们正在吸入四种浓度逐渐增加的支气管收缩剂，而实际上受试者吸入的溶液是雾化的等渗盐水。10名受试者对暗示的反应是特异性气道阻力增加超过20%，但这种反应无法通过哮喘对情绪触发因素的感知报告来预测。哮喘对情绪唤起的反应感知并不能预测气道对支气管收缩暗示的反应，这一发现可能意味着，在研究心理因素在哮喘激发中的作用时，暗示是一个无效的替代变量。
