HPRQ, Healthcare Provider Relational Quality; PETS, Patient Experience with Treatment and Self-management; PMCSM, Perceived Medical Condition Self-Management scale; SD, standard deviation.
↵† Analyses control for the following demographic characteristics: age, sex, race, and education status.
↵‡ A higher PETS score indicates greater treatment burden, with a score range from 0 to 100.
↵§ A higher PMCSM score indicates greater self-efficacy (Wallston et al., 2011).
↵‖ A higher single item literacy screener score indicates lower subjective health literacy. (Morris et al., 2006).
↵¶ A higher single item score indicates more financial difficulties due to medical treatment or physical condition (Eton et al., 2017).
↵# A higher HPRQ score indicates better HPRQ (Eton et al., 2017).
