Key result
Perceived control partially mediates the link between depressive symptoms and physical symptom severity in HF.
Why the study?
Depressive symptoms may affect the severity of physical symptoms in patients with heart failure, and perceived control has positive effects, but whether perceived control mediates this relationship was unknown.
Does perceived control mediate the relationship between depressive symptoms and physical symptom severity in patients with heart failure?
Cross-Sectional (n=300)
Yes
Does perceived control mediate the relationship between depressive symptoms and physical symptom severity in patients with heart failure?
Perceived control partially mediates the relationship between depressive symptoms and physical symptom severity in heart failure patients, suggesting a potential psychological target for symptom management.

Hypothesis-generating for depressive symptoms and perceived control in HF symptom burden; prospective trials needed before clinical adoption.
Shortness of breath (SoB), sleep disturbance, and fatigue are the most common physical symptoms (PS) among patients with Heart Failure (HF). Depressive symptoms (DS) are the most common psychological symptoms that might affect the severity of PS. Perceived control (PC) has positive effects among patients with HF. This study determined whether PC mediated the relationship between DS and PS severity among patients with HF. Three hundred participants were recruited conveniently from four hospitals in Amman, Jodan. Arabic versions of the Hospital Anxiety and Depression Scale, the Control Attitude Scale-Revised, and the Symptom Status Questionnaire-Heart Failure were used to collect the data. Baron and Kenny's approach through multiple regression demonstrated that DS and PC were independent predictors for sleep disturbance, SoB, and fatigue. This indicated that PC partially mediated the relationship between DS and PS severity. Addressing DS and PC may reduce symptoms; future research should evaluate longitudinal and interventional effects.

AbuRuz et al. (2026) conducted a cross-sectional in Heart Failure (n=300). Perceived control was evaluated on Mediation of the relationship between depressive symptoms and physical symptoms severity. Perceived control partially mediated the relationship between depressive symptoms and physical symptom severity (sleep disturbance, shortness of breath, and fatigue) in patients with heart failure.
