ABSTRACT=<p>The article presents findings from three studies designed to validate and culturally adapt the Polish version of the <italic>Revised Illness Perception Questionnaire</italic> (IPQ-R), a measure of the cognitive and emotional components of illness representations among oncology patients. The tool is conceptually based on Leventhal’s Self-Regulatory Model (<xref ref-type="bibr" rid="B44">Leventhal et al., 1984</xref>, <xref ref-type="bibr" rid="B42">2001</xref>). The results of the study 1 (<italic>n</italic> = 40) show that it can be successfully used in a Polish cultural context as a reliable equivalent to its original English version (<xref ref-type="bibr" rid="B48">Moss-Morris et al., 2002</xref>). Analyses conducted in Study 2 (<italic>n</italic> = 318) provided good evidence for construct and criterion validity as well as the internal reliability of the IPQ-R subscales. Study 3 (<italic>n</italic> = 54) revealed that the IPQ-R subscales present good test–retest reliability. Overall, the results show that the Polish version of the IPQ-R provides a comprehensive and psychometrically acceptable assessment of the representation of cancer and can be reliably used in studies involving Polish oncology patients.</p>
