Selected psychological aspects and medication adherence in oncological patients

OBJECTIVE: The aim of this study was to analyze the relationships between selected psychological features and adherence to therapy in oncological patients. METHODS: The study included 102 patients of oncological clinics, 66.67% of whom were female. The average (SD) age of the study subjects was 49.15 ± 18.16 years old. The following tools were used: Morisky Medication Adherence Questionnaire (MAQ‐4), Multidimensional Health Locus of Control, Coping Inventory for Stressful Situations, Personal Values Inventory (LWO), and a study‐specific survey questionnaire. RESULTS: High MAQ‐4 scores were declared by 39.2% of the subjects, medium scores by 32.3% and low scores by 28.5%. The values were higher in female patients (P = .23), younger subjects (P < .001), and in individuals with higher education (P = .03). The greatest adherence was observed in subjects who placed their locus of control in chance (P = .022). Significant relationships were identified between the level of medication adherence and the use of avoidance strategies of coping with stress (P = .037), including the willingness to engage in social relationships (P = .04). It was demonstrated that the risk of noncompliance in the analyzed group was associated with a lower assessment of appearance (OR = 0.75) and health (OR = 0.78) on the scale of values. CONCLUSION: Medication adherence in oncological patients is related to the health locus of control, strategies of coping with stress, and the value assigned to appearance and health.
