Talking the same language on patient empowerment: Development and content validation of a taxonomy of self-management interventions for chronic conditions.

Context: The literature on self-management interventions (SMIs) is growing exponentially, but it is characterized by heterogeneous reporting that limits comparability across studies and interventions. Building an SMI taxonomy is the first step towards creating a common language for stakeholders to drive research in this area and promote patient self-management and empowerment.

Objective: To develop and validate the content of a comprehensive taxonomy of SMIs for long-term conditions that will help identify key characteristics and facilitate design, reporting and comparisons of SMIs.

Methods: We employed a mixed-methods approach incorporating a literature review, an iterative consultation process and mapping of key domains, concepts and elements to develop an initial SMI taxonomy that was subsequently reviewed in a two-round online Delphi survey with a purposive sample of international experts.

Results: The final SMI taxonomy has 132 components classified into four domains: intervention characteristics, expected patient/caregiver self-management behaviours, outcomes for measuring SMIs and target population characteristics. The two-round Delphi exercise involving 27 international experts demonstrated overall high agreement with the proposed items, with a mean score (on a scale of 1-9) per component of 8.0 (range 6.1-8.8) in round 1 and 8.1 (range 7.0-8.9) in round 2.

Conclusions: The SMI taxonomy contributes to building a common framework for the patient self-management field and can help implement and improve patient empowerment and facilitate comparative effectiveness research of SMIs.
