Abstract

Background:

Patient adherence, the level of asthma self-management skills, exposure to stress, and depression can have considerable influence on a wide range of asthma outcomes and thus are considered asthma outcome mediators.

Objective:

National Institutes of Health institutes and other federal agencies convened an expert group to recommend standardized measures for 7 domains of asthma clinical research outcomes measures. Although the review of mediators of these outcomes was not within the scope of any specific outcome topic, a brief summary is presented so that researchers might consider potential mediators.

Methods:

We prepared a summary of key mediators of asthma outcomes based on expertise and knowledge of the literature.

Results:

The rationale for including measures of adherence, self-management skills, and exposures to stress in asthma clinical research is presented, along with a brief review of instruments for collecting this information from clinical research participants.

Conclusions:

Appropriate measurement of adherence, self-management skills, and exposures to stress will enhance characterization of study participants and provide information about the potential impact these factors can have on mediating the effects of treatment interventions.
