Processes of change in an asthma self-care intervention.

In this article, we present a qualitative exploration of the psychological and communication processes that occur within an intervention to improve self-care for people with asthma. In the context of a primary-care-based trial of the intervention, we collected data at three time points for 21 patients, comprising 2 audiotaped consultations (nurse and patient together) and individual semistructured interviews 3 months after the second consultation. Using framework analysis, we identified both psychological processes (illness understanding, affective response to asthma, and reasoned motivation) and patient-provider interactions (active patient involvement and individual tailoring). We use these findings to extend and refine the pre-existing theoretical model of behavior change underpinning the intervention, in particular with relation to patient-provider interaction processes. We conclude that it is important for developers and providers of asthma self-care interventions to attend to the style of delivery as well as the behavior change techniques involved.
