Background: Assessment of malnutrition is important in cancer patients. The Scored Patient-Generated Subjective Global Assessment (PG-SGA), an instrument that enables interdisciplinary assessment of malnutrition and its risk factors, was not available in Dutch. Objective: Translation and cultural adaption of the original English PG-SGA to the Dutch setting. Methods: The PG-SGA was translated and culturally adapted, following the International Society for Pharmacoeconomics and Outcomes Research principles. Perceived content validity, comprehensibility, and difficulty were explored among a multidisciplinary sample of healthcare professionals and their cancer patients. Content validity, comprehensibility, and difficulty were operationalized by calculating item and scale indices. On scale level, indices of 0.80 to 0.90 were considered acceptable, and indices of 0.90 or greater were considered excellent. Results: Consensus was reached on 91 and 8 differences in the forward and back translations, respectively. Scale Content Validity Index was 0.89. Scale Comprehensibility Index and Scale Difficulty Index of the patient-generated component of the PG-SGA were 0.99 and 0.96, respectively. Scale Comprehensibility Index and Scale Difficulty Index of the professional component were 0.81 and 0.55, respectively. Conclusions: Translation and cultural adaptation of the PG-SGA according to the International Society for Pharmacoeconomics and Outcomes Research principles resulted in a Dutch version that maintained the purpose, meaning, and format and have acceptable content validity. Now a Dutch version of the PG-SGA is available that is considered comprehensible and easy by patients, and comprehensible and relevant by professionals. However, the professional component was considered difficult by the PG-SGA–naive professionals, which indicates a need for training. Implications for Practice: A similar systematic approach for future translations of the PG-SGA is recommended, to safeguard cultural equivalence.

Rationale: The Patient-Generated Subjective Global Assessment (PG-SGA) is a validated instrument to assess and monitor malnutrition, which consists of both patient-reported and professional-reported items. A professional should be able to correctly interpret all items. Untrained professionals may experience difficulty in completing some items of the PG-SGA. We aimed to explore the change in perceived comprehensibility and difficulty of the Dutch PG-SGA by health care professionals on the use of the instrument, before and after training. Methods: A sample of 36 untrained health care professionals, of which 34 dietitians, completed a set of 29 items on a four point scale regarding comprehensibility and difficulty of the PG-SGA on two separate occasions: T0) two weeks before and T1) directly after an instructional session on the PG-SGA and training with the physical exam. Summarized comprehensibility indexes (SCI) and difficulty indexes (SDI) were calculated for the patient part of the PG-SGA (aka PG-SGA Short Form; PG-SGA SF), the professional part of the PG-SGA (PG-SGApro) and the full PG-SGA, to quantify the level of perceived comprehensibility and difficulty. SCI≥0.80 and SDI≥0.80 were considered acceptable, SCI≥0.90 and SDI≥0.90 were considered excellent. Results: SCI of the PG-SGA SF was acceptable both before (SCI: 0.80) and after training (SCI: 0.89). SCI of the PG-SGApro and full PG-SGA changed from unacceptable (SCI: 0.64; 0.69) to excellent (SCI: 0.95; 0.94). All SDIs changed from unacceptable (SDI for respectively PG-SGA SF, PG-SGApro and full PG-SGA: 0.71; 0.50; 0.57) to acceptable (SDI: 0.88; 0.85; 0.87). Conclusion: Training professionals in the use of the PG-SGA can be an effective strategy for improving the level of both comprehensibility and difficulty.
