BackgroundSelf-management support interventions are widely accepted in chronic kidney disease (CKD) care; however, interventions rarely consider individual behaviors by incorporating a behavioral theoretical framework. The Theoretical Domains Framework (TDF) can be used to facilitate an understanding of patients and their caregivers' behaviors to successfully self-manage CKD.Objectives(1) To understand behaviors of patients with CKD and their caregivers and identify potential intervention approaches to support CKD self-management and (2) to explore relationships between the 14 TDF domains and CKD self-management.DesignQualitative descriptive study using both content and thematic analysis.SettingPurposive criterion was used to recruit participants from across Canada.PatientsCanadian patients with CKD and their caregivers.MeasurementsFocus groups and telephone interviews using a semistructured interview guide.MethodsWe conducted a secondary analysis of qualitative data collected from focus groups and telephone interviews from July 2017 to January 2018. Two research team members coded the transcribed data to the 14 TDF domains using a modified approach of the Framework Method. We linked the common TDF domains to relevant intervention functions from the Behaviour Change Wheel (BCW) to identify potential intervention approaches. We also identified and mapped relationships between the relevant TDF domains to report emerging themes.ResultsSix focus groups (37 participants) and 11 telephone interview transcripts were analyzed. Five TDF domains that influenced CKD self-management behavior were identified: environmental context and resources, knowledge, beliefs about capabilities, beliefs about consequences, and social influences. Four BCW intervention functions were identified: education, modeling, persuasion, and environmental restructuring. Four emergent themes, shaped by the populated 14 TDF domains, were identified: What does this mean for me? Help me help myself, How does this make me feel? and Who am I?LimitationsThe TDF was not used to design the interview guide; therefore, there may be underrepresentation of some TDF domains relevant for self-management.ConclusionOur findings highlight 5 TDF domains that can influence CKD self-management behavior and 4 possible intervention approaches to influence behavior change in patients with CKD and their caregivers. Emergent themes highlight participants' interpretation of being diagnosed with CKD, their motivations, feelings, values, and altered identity. This work will inform the codesign of a behavior change intervention to enhance patient self-management of CKD.
