Background. Illness representations determine a patient's successful adaptation in the context of chronic somatic illness.

Objective. The study had its purpose to investigate and compare the illness representations in the patients with acute leukemia and lymphoma.

Study Participants. The study involved 109 respondents: 51 patients with acute leukemia aged 18 to 64 years (Mage = 35.12; SD = 12.90; 28 women) and 58 patients with lymphoma aged 19 to 64 years (Mage = 42.22; SD = 11.17; 41 women).

Methods. The study implemented the following methods: “Illness Perception Questionnaire-Revised” (IPQ-R), “Health Anxiety Inventory” (HAI), “Cognitions About Body and Health Questionnaire” (CABAH), and the “Scale of Assessment of Illness Behavior” (SAIB). Descriptive statistics and group comparison methods (Student's t-test) were used to process quantitative data.

Results. A comparative analysis of the data obtained showed that patients with acute leukemia have more difficulty in identifying the disease, were more certain about the negative impact of the disease and its unstable course, were more likely to overestimate symptom severity, and paid more attention to implementing treatment- and medication-related behaviors compared to patients with lymphomas.

Conclusions. The main targets of psychological work with patients with acute leukemia are their ideas about the disease identity, its unstable course and negative consequences, their tendency to overestimate the symptom severity and underestimate the importance of preventive behavior associated with treatment and medication. Common targets of psychological work with patients with acute leukemia and lymphoma are their ideas about the short-term course of the disease and negative emotional experiences about their disease.
