Asthma Clinical Trial - Motivational Interviewing for Medication Adherence

Status Completed

Clinical Trial Summary

The high burden of asthma appears to be related to poor asthma control, which is associated with more frequent asthma symptoms, greater bronchodilator use and functional impairment, and worse pulmonary function. Despite the availability of effective treatments, more than 58% of asthmatics are poorly controlled. Daily adherence to inhaled corticosteroid (ICS) regimens is considered by experts to be one of the most important behavioral factors linked to achieving optimal asthma control. However, there is a paucity of research on interventions specifically designed to improve ICS adherence among adult asthmatics. The vast majority of intervention studies to date used atheoretical interventions to target behavior change, relying mainly upon educational approaches which have been criticised for "failing to translate knowledge into action." This may be due to the fact that most education-based approaches do not specifically address or help patients overcome ambivalence about behavior change, which is necessary for ensuring daily adherence. Motivational interviewing (MI) is a client-centred intervention that focuses on enhancing intrinsic motivation to change a particular behavior, and exploring and resolving ambivalence about behavior change. Brief MI sessions (e.g., 1-5 x 15-30 minute sessions) have been shown to improve a variety of health behaviors (e.g., reduce alcohol consumption, improve dietary habits, increase exercise behaviour, and improve medication adherence) and health outcomes (reduce blood pressure, body mass index, and cholesterol levels). However, no studies to date have assessed the efficacy of using MI to improve ICS adherence in asthmatics. This study aims to assess the efficacy of using MI to improve daily medication (ICS) adherence in a sample of poorly controlled, non-adherent asthmatics. It is hypothesized that patients randomized to the MI condition will exhibit significantly improved ICS adherence at 6 and 12-months post-intervention, independent of baseline levels and covariates, relative to patients randomized to the usual care control condition.

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
