Recruitment, retention, and intervention adherence for a chronic illness self-management intervention with the Apsáalooke Nation.

Recruitment, retention, and adherence within health intervention research have been understudied in Indigenous communities, where well-known health disparities exist. The purpose of this paper is to describe planned versus actual recruitment, retention, and adherence strategies and the evaluation of retention and adherence strategies for a community-based research study of a Chronic Illness (CI) self-management intervention within an Indigenous community. A Community-Based Participatory Research (CBPR) approach was used to develop and implement Báa nnilah, a culturally consonant educational intervention to improve CI self-management.

Reliability, construct validity, and measurement invariance of the PROMIS Physical Function 8b-Adult Short Form v2.0.

Purpose: The National Institutes of Health established the Patient-Reported Outcomes Measurement Information System (PROMIS) to assess health across various chronic illnesses. The standardized PROMIS measures have been used to assess symptoms in studies that included Native American participants, although the psychometric properties of these measures have not been assessed among a solely Native American population. This study aimed to assess the reliability, construct validity, and measurement invariance of a widely used PROMIS Physical Function survey among Native Americans residing on or near the Apsáalooke (Crow) Reservation who were living with chronic illnesses.
