Effectiveness of a group-based intervention to change medication beliefs and improve medication adherence in patients with rheumatoid arthritis: a randomized controlled trial.

Objective: To assess the effect of a group-based intervention on the balance between necessity beliefs and concern beliefs about medication and on medication non-adherence in patients with rheumatoid arthritis (RA).

Methods: Non-adherent RA patients using disease-modifying anti-rheumatic drugs (DMARDs) were randomized to an intervention or control arm. The intervention consisted, amongst others, of two motivational interviewing-guided group sessions led by the same pharmacist.

Development and content of a group-based intervention to improve medication adherence in non-adherent patients with rheumatoid arthritis.

Objective: To describe the systematic development and content of a short intervention to improve medication adherence to disease-modifying anti-rheumatic drugs in non-adherent patients with rheumatoid arthritis (RA).

Methods: The intervention mapping (IM) framework was used to develop the intervention. The following IM steps were conducted: (1) a needs assessment; (2) formulation of specific intervention objectives; (3) inventory of methods and techniques needed to design the intervention and (4) production and piloting of the intervention.
