Cultural Adaptations of Healthcare Interventions: A Step-by-Step Guide.

Area of Science:

• Implementation Science
• Health Services Research
• Cultural Adaptation

Background:

• Cultural adaptations enhance healthcare intervention effectiveness, acceptability, and equity.
• Existing frameworks lack practical guidance for applied healthcare settings.
• Underreporting of adaptation processes hinders transparency and reproducibility.

Purpose of the Study:

• To present a structured, step-by-step guide for culturally adapting healthcare interventions.
• To address the gap in practical, transferable guidance for adaptation processes.
• To use the 'I Manage My Meds' toolkit as a case study for adaptation.

Main Methods:

• A methodological case study approach was employed.
• An eight-step, iterative guide was developed, integrating a phased structure model with the Ecological Validity Model (EVM).
• Development involved collaboration with community stakeholders, patients, public contributors, translators, and researchers.

Main Results:

• A practical, step-by-step guide for planning, implementing, documenting, and refining cultural adaptations was developed.
• Key findings indicate adaptations are cyclical, deep-level changes may require reframing assumptions, and sustained collaboration is crucial.
• The guide is designed for transferability across diverse populations, settings, and intervention types.

Conclusions:

• This paper offers practical methodological guidance to implementation research.
• The transparent and replicable guide facilitates consistent documentation of cultural adaptation processes.
• Wider adoption can improve the quality, equity, and reproducibility of culturally adapted healthcare interventions.
