چکیده انگلیسی

Objective Optimal self-care is crucial in patients with chronic heart failure (HF). While the focus of research has been on negative mood states, adequate psychological resources may be required to successfully engage in HF self-care. Therefore, the longitudinal associations of multiple positive affect measures in explaining HF self-care including consulting behavior were examined while adjusting for depressive symptoms and potential covariates (e.g., disease severity). Methods In this prospective cohort study, 238 patients (mean age: 66.9 ± 8.6 years, 78% men), with chronic HF completed questionnaires at baseline and 1-year follow-up. Positive affect was assessed with the Positive and Negative Affect Schedule (PANAS) and the Global Mood Scale (GMS). Anhedonia, i.e. diminished interest or pleasure, was assessed with a subscale of the Hospital Anxiety and Depression Scale (HADS). The 9-item European Heart Failure Self-care Behaviour scale was completed to assess HF self-care including consultation behavior. Results Linear mixed modeling results showed that anhedonia was most strongly associated with both poor self-care (estimate = − .72, P < .001) and consulting behavior (estimate = − .44, P < .001) over time, after adjustment for covariates and depressive symptoms. GMS positive affect was related to better HF self-care adjusting for standard depressive symptoms but not when adjusting for anhedonia. PANAS positive affect was not independently related to self-care. Conclusion Anhedonia was associated with worse compliance with self-care among chronic HF patients over time, irrespective of disease severity and depression. Associations between positive affect and self-care were dependent on the measures used in multivariable analyses.

مقدمه انگلیسی

Chronic heart failure (HF) is a growing major public health problem affecting 1–2% of the general population in developed countries, due to the aging of the population and increased survival after an acute cardiac event [1] and [2]. Despite the improvement of HF treatment, it is associated with high morbidity and mortality rates, impaired health status, and high number of hospital (re-)admissions which has led to major healthcare costs [3] and [4]. From the patient perspective, chronic HF is a burdening condition as it requires a vast amount of self-care [5]. Self-care refers to the actions patients must undertake to maintain healthy functioning and well-being by actively managing symptoms, treatment, and lifestyle changes inherent in living with a chronic medical condition [6]. Maintaining health can be achieved by adapting behaviors such as complying with medication and lifestyle regimen, and consulting professionals when chronic HF symptoms worsen (i.e., consultation behavior) [6]. Critically, poor self-care has been associated with adverse outcomes in patients with chronic HF [7]. A multitude of different factors affect and complicate chronic HF self-care behavior [5]. Adequate psychological resources are required to provide patients with the necessary motivation and energy to successfully engage in optimal self-care. While the focus of research has been on negative mood states such as depression, it is being debated whether positive affect should be considered as the opposite as both states can be experienced simultaneously [8] and [9]. Relatively little is known about the health effects of positive psychological affect (i.e., mood states such as feeling active, joy or cheerful) but preliminary evidence suggests that positive affect may be associated with enhanced cardiovascular health [10], [11] and [12], healthy lifestyle (e.g., physical activity) [11], and adaptive biological function (e.g., reduced inflammation) [11] and [13]. To date, no consensus exists on the definition and measurement of positive affect and it has recently been stressed that research should include multiple constructs of positive affect to examine its relationship with cardiovascular health outcomes and behaviors [11]. It was previously reported that different positive affect measures reflected different dimensions of positive affect using factor analysis in the current HF sample and that these dimensions were also distinctively related with inflammatory biomarkers [13]. One of these measures has been assumed to assess anhedonia [12], a core feature of major depressive disorder that is defined as diminished interest in or pleasure in response to stimuli that were previously experienced as rewarding during a pre-morbid state (DSM-IV-TR) [14]. Remarkably, while it is often assumed that depression is associated with poor compliance in patients with HF, findings have been inconsistent in confirming this relationship so far [15] and [16]. Given these inconsistencies and the assumption that positive affect is not merely the opposite of negative affect, it is of interest whether positive affect and/or anhedonia are associated with compliance with HF self-care activities and consultation behavior as potential behavioral determinants of health outcomes. Therefore, we prospectively examined and compared the associations of positive affect and anhedonia with compliance with self-care behaviors at baseline and 1-year follow-up among patients with chronic systolic HF using several affect measures. In addition, we examined whether disease severity, depressive symptoms, or other potential covariates could explain these associations.
