Intentional nonadherence to prescribed treatment has been documented as a leading contributor to the deleterious outcomes observed for many heart failure patients. Investigation of adherence from the perspective of the patient and spouse/partner offers a different approach to the complexities of intentional nonadherence. The purpose of this study was to examine the relationship between patients' and spouse/partners' illness representations or perceptions of the symptoms, cause, time-line, consequences, and control of heart failure and the patients' adherence behavior. Congruence between patients and spouse/partners in perceptions was investigated to determine if congruence or lack of congruence affected patients' adherence behavior. The Self-Regulatory Model of Illness, which specifically incorporates personal perspectives of an illness, provided the theoretical framework for the study. The study design was a descriptive correlational survey. The Illness Perception Questionnaire and Adherence Estimation Questionnaire were used to determine illness representations and adherence estimation in a sample of 60 older adult heart failure patients and their spouse/partners. Descriptive statistics, Pearson's moment correlational coefficients, hierarchical multiple regression analysis, paired-samples, and independent-samples t tests were used to analyze the data. Patients' and spouse/partners' perceptions of symptoms and spouse/partners' perceptions of the time-line for heart failure were significantly related to patients' adherence behavior. The addition of the spouse/partners' illness representations to the patients' illness representations explained 52% of the variance in patients' adherence behavior. A significant linear relationship was not found between the amount of congruence between patients and spouse/partners and patients' adherence behavior. However, patient adherence increased when patients and spouse/partners were congruent in perceptions of control of heart failure. The findings suggest that further research in illness representation and adherence with consideration of the spouse/partner is warranted. Further study is needed with a more representative sample and in other chronic illnesses to refine the study instruments and see if different attributes of the illness representation come forth as significantly related to patients' adherence behavior.
