WHOQoL-SRPB: World Health Organization Quality of Life Spirituality, Religiosity and Personal Beliefs; REMADHE: Repetitive Education and Monitoring for Adherence for Heart Failure; OR: odds ratio; CI: confidence interval; WHOQoL-Bref: World Health Organization Quality of Life; MLHFQ: Minnesota Living with Heart Failure Questionnaire; PHQ-9: Patient Health Questionnaire 9; DUREL: Duke University Religion Index.

Model 1 – adjusted for demographic and clinical variables selected by clinical significance;

Model 2 – adjusted for demographic and clinical variables selected by significance in univariate analyses;

Model 3 – adjusted for other psychosocial instruments of quality-of-life, depression and religiosity; Odds ratio represents the magnitude of association per 1-point increase in each score
