Anxiety reduction in asthma: four catches to general application.

Anxiety reduction procedures as adjuncts to medical treatment have almost invariably been reported to benefit asthmatic patients in individual case studies. However, the results of more systematically controlled studied are clearly inconsistent. This discrepancy is understandable in view of what is now known about anxiety in asthma. Four catches, each based on what has been reported about the roles and forms of anxiety in asthma, are presented. Each catch argues against general, across-the-board application of anxiety reduction procedures in asthma. Careful evaluation leading to more problem-oriented treatment is needed in view of the different roles of anxiety in asthma.
