Abstract

Background: Chemotherapy Induced Peripheral Neuropathy (CIPN) is a common and debilitating adverse effects caused by the infusion of neurotoxic chemotherapeutics such as taxanes, platines, vinca alkaloids, bortezomib and thalidomide. The administration of these medications increase patient survival, however, approximately 30% to 40% develop CIPN, which negatively affects the planned treatment and the quality of life by interfering with daily activities of the patient. The CIPN manifests itself with sensory symptoms (paresthesia, dysesthesia, pain and others), motors (weakness, changes in gait and balance, difficulty with fine motor skills and others) and neurovegetative (constipation, urinary retention, sexual dysfunction and changes in blood pressure). So far, it has not been a tool designed to evaluate the neuropathic pain in CIPN and furthermore, there is no validated instrument for this purpose in Brazil. Aims: To perform the translation and cultural adaptation of Chemotherapy- Induced Peripheral Neuropathy Assessment Tool instrument (CIPNAT) into Portuguese of Brazil and test the psychometric properties of the adapted version in a sample of cancer patients with CIPN. Methods: This is a methodological study with cross data collection. For the process of translation and adaptation of the instrument, it was adopted the methodological theoretical framework proposed by Beaton et al (2000). Data collection occurred in two referral hospitals in the oncological treatment of São Paulo. Results: There was obtained a sample of 245 participants, and that 135 (55.1%) had colorectal neoplasm, 162 (66.1%) used a platinum chemotherapeutic agent, 125 (51%) manifested numbness in the hands with medium gravity of 6.71 and average distress of 7.0 (on a scale of 0-10), impacted negatively on the activities of Daily Living (ADLs) such as exercise, work and leisure activities. To test the convergent validity has made a Spearman\' correlation of the adapted version of CIPNAT with NPSI and DN4 instrument and, was obtained a moderate correlation. Could not achieve the discriminant validity. Exploratory factor analysis with varimax rotation identified two factors, which are, sensory symptoms and motor symptoms. Regarding reliability, it was reached a Cronbach\'s alpha of 0.87, satisfactory. The test-retest showed a strong correlation between the first and second evaluation by CIPNAT and is considered stable. Conclusion: The psychometric analysis of CIPNAT was adequate. Thus, it will be available a valid and reliable instrument that tracks, features, evaluates and measures the CIPN and its impact on ADL for the oncology nursing promotes safe and quality care (AU)
