The mediating role of trust in physician and self-efficacy in understanding medication adherence in severe asthma - 08/12/21
Abstract |
Objective |
To investigate the relationships between beliefs about medication, trust in physician, self-efficacy, and medication adherence in severe asthma patients.
Methods |
A sample of 117 patients with a diagnosis of Severe Asthma on Step 4 or 5 of GINA assessment of control treatment ladder completed a one-time survey, including the shortened Medication Adherence Report Scale (MARS-5), Beliefs about Medicines Questionnaire (BMQ), Trust in Physician Scale (TIPS), and Self-Efficacy in Taking Medication (SEAMS).
Results |
Our study found that medication adherence was associated with trust in physician (p = 0.033); factor one of beliefs about medication - Necessity of taking medication (BMQ1-Necessity: p = 0.025); and two factors of self-efficacy in taking medication (SEAMS1-Difficulty: p = 0.001; SEAMS2-Uncertain: p = 0.005). Furthermore, two factors of self-efficacy and trust in physician together significantly mediated the relationship between beliefs about medication and medication adherence in a serial multiple mediator model.
Conclusions |
Beliefs about medication are fundamental in affecting asthma patients’ trust in physician and self-efficacy, which in turn impact medication adherence.
Clinical implications |
Interventions being developed to improve medication adherence may benefit from emphasizing on asthma patients' concerns about overuse and harm of medication. In addition, education program targeting to improve provider-patient relationship could help with patients’ confidence in taking medication.
