PURPOSE: Providing sufficient information about diagnosis and treatment is an important feature of high-quality patient care in oncology. To measure patient satisfaction with information received, the European Organisation for Research and Treatment of Cancer Quality of Life Group has recently developed a new tool, the information module (INFO25). The aim of this study was to evaluate the scale structure of the INFO25. METHODS: A total of n = 423 patients completed the INFO25 after finishing cancer therapy. The internal consistency of multi-item subscales was calculated using Cronbach's Alpha. The scale structure was evaluated using multi-trait methods and confirmatory factor analysis. RESULTS: Cronbach's Alpha of the multi-item scales ranged from 0.79 to 0.88. Only two items correlated somewhat higher with another scale than with their own, indicating a good scale structure. Construct validity with latent variable models, including a general information factor and four multi-item scales, resulted in the following fit indices CFI = 0.96, RMSEA = 0.08, TLI = 0.99 and WRMR = 1.03. CONCLUSION: The suggested construct of the INFO25 with a total score (general factor) in addition to the subscales is valid.
