Abstract
BACKGROUND: Assessment of Rehabilitation Needs Checklist (ARNC), has been developed to assess rehabilitation need in cancer patients and is recommended by the Confederation of Regional Cancer Centres in Sweden, known as Hälsoskattningen. The aim of the study was to test the reliability and validity of the ARNC, mainly by comparing it with the Distress thermometer and EORTC QLQ-C30. METHODOLOGY: A sample of 993 persons identified in the Swedish cancer register. The study participants were diagnosed with cancer in 2021 in the Mid Sweden region. The psychometric methods tested reliability and validity including factor analysis. RESULTS: The response rate was 38%. The test-retest analysis showed that ICC was 0.80 or higher for 12 of the ARNC items. A strong or modarete correlation between ARNC and the other instruments was found in all functional scales and for most items. CFA of the 13-item two-factor model showed a RMSEA value of 0.04, CFI and TLI values of 0.97 and 0.96, and a SRMR value of 0.05, indicating a satisfactory model fit. CONCLUSION: The evaluation of the ARNC suggests that it is an acceptable and reliable screening instrument for detecting symptoms and signs indicating a possible need of rehabilitation. The medium to strong correlations between ARNC items and the EORTC QLQ- C30 items and scales suggest that ARNC could be an alternative also for research purposes when a shorter and less comprehensive instrument is needed. The simple design could be an advantage as it lowers the burden on cancer patients.
