Measures included the telephone-Montreal Cognitive Assessment (t-MoCA (c)), Patient Health Questionnaire-9, Brief Test of Adult Cognition by Telephone, Basel Assessment of Adherence to Immunosuppressive Medications Scale, and the Brief Illness Perceptions Questionnaire. Descriptive statistics, point-biserial correlations, Pearson's correlations, and logistic regression were used to describe relationships.Results: Of the 35 participants (mean age: 61 years [SD: 10.3], 71.4% male, 71.4% white), 31.4% (n = 11) were classified as nonadherent to their immunosuppression medications. Higher immediate word recall, indicating better episodic memory (memory for autobiographical and recent events), and higher illness coherence scores were associated with not missing doses of medication. Higher t-MoCA (c) total scores, indicating normal cognitive function, and lower depression scores were associated with taking medications on time. More than 22% (n = 8) of participants scored less than 19 on the t-MoCA (c), an indication of mild cognitive impairment.Conclusion: Cognitive impairment may be more common among heart transplant recipients than what is currently recognized, and specific domains of cognitive function were related to medication adherence after transplantation in this study. Future studies should include longitudinal evaluations of cognitive function, depression, and medication adherence. Consideration of these relationships is needed when designing adherence-promoting interventions for this population. 收起
