Brief 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 behavioural 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 behaviour 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 behaviour change, which is necessary for ensuring daily adherence. Motivational communication (MC) is a client-centred intervention that focuses on enhancing intrinsic motivation to change a particular behaviour, and exploring and resolving ambivalence about behaviour change. Brief MC sessions (e.g., 1-5 x 15-30 minute sessions) have been shown to improve a variety of health behaviours (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 MC to improve ICS adherence in asthmatics. This study aims to assess the efficacy of using MC to improve daily medication (ICS) adherence in a sample of poorly controlled, non-adherent asthmatics. It is hypothesized that patients randomized to the MC 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.

Outcome Measures

Primary Outcomes (1)

  • Inhaled corticosteroid adherence

    Inhaled corticosteroid adherence measured according to the following validated equation: # of treatment days (based on the # of canisters filled at the pharmacy x the duration of each prescription) divided by the # of prescription days (# of days the patient is expected to be taking his/her medication)

    12 months post-intervention

Secondary Outcomes (5)

  • Inhaled corticosteroid adherence

    6 months post-intervention

  • Asthma Control Questionnaire (Juniper)

    12 months post-intervention

  • Asthma Control Test

    12 months post-intervention

  • Asthma Self-Efficacy Scale (Tobin)

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Patients 18 years and older
  • Primary diagnosis of moderate-severe persistent asthma (as per GINA)
  • Prescribed inhaled corticosteroid medication (min dose of 250 µg fluticasone equivalent per day) for at least 12 consecutive months
