Adherence to therapy among liver transplant patients as related to depression, anxiety, acceptance of the disease, and social support.

Objective: This study aimed to assess the patients' adherence to therapeutic regimens after liver transplantation, taking into account the levels of depression and anxiety, acceptance of the disease, and social support.
Patients and Methods: The study group included N = 112 patients selected from 669 patients after liver transplantation. The Delphi method was used to develop a tool to assess the level of adherence to treatment regimens. The sources of data for this study were recommendations and the work of an expert panel. The next method used in the study was a diagnostic survey based on the following standardized research instruments: Inventory of Socially Supportive Behaviors (ISSB), Acceptance of Illness Scale (AIS), Beck Depression Inventory-II (BDI-II) and State-Trait Anxiety Inventory (STAI).
Results: The study group showed a medium level of adherence to therapeutic recommendations (6.8 ± 1.85). We observed a statistically significant positive correlation between acceptance of the disease and adherence to therapeutic recommendations (r = -0.20, t = -2.040, p = 0.044). Among the factors analyzed, six predictors were identified that significantly affect the level of adherence to therapeutic recommendations in a group of liver transplant patients.
Conclusions: 1. Patients who accept their disease are a group of people who significantly worse adhere to therapeutic recommendations. 2. The main positive predictors of treatment adherence in the group of transplant patients are the search for various sources of information and declarative adherence to treatment recommendations. Negative predictors include the duration of the disease, side effects of the applied treatment, and comorbidities. 3. The patients who were informed that results depend on regular medication intake significantly more often followed therapeutic recommendations.
