The Patient-Generated Subjective Global Assessment (PG-SGA) is an instrument used to assess malnutrition and its risk factors. Some items of the PG-SGA may be perceived as hard to comprehend or as difficult by healthcare professionals. The present study aimed to determine whether and how dietitians' perceptions of comprehensibility and difficulty of the PG-SGA change after a single training in PG-SGA use.
In this prospective evaluation study, Dutch PG-SGA-naïve dietitians completed a questionnaire regarding perceived comprehensibility and difficulty of the PG-SGA before (T0) and after (T1) receiving a single training in the use of the instrument. Perceived comprehensibility and difficulty were operationalised by calculating item and scale indices for comprehensibility (I-CI, S-CI) and difficulty (I-DI, S-DI) at T0 and T1. An item index of 0.78 was considered acceptable, a scale index of 0.80 was considered acceptable and a scale index of 0.90 was considered excellent.
A total of 35 participants completed the questionnaire both at T0 and T1. All item indices related to comprehensibility and difficulty improved, although I-DI for the items regarding food intake and physical examination remained below 0.78. Scale indices for difficulty and comprehensibility of the PG-SGA changed significantly (P < 0.001) from not acceptable at T0 (S-CI = 0.69; S-DI = 0.57) to excellent for comprehensibility (S-CI = 0.95) and acceptable for difficulty (S-DI = 0.86) at T1.
The findings of the present study suggest that significant improvement in PG-SGA-naïve dietitians' perception of comprehensibility and difficulty of the PG-SGA can be achieved quickly by providing a 1 day of training in the use of the PG-SGA.
患者主观整体评估（PG-SGA）是一种用于评估营养不良及其风险因素的工具。PG-SGA 的某些项目可能被医疗保健专业人员认为难以理解或困难。本研究旨在确定营养师在接受一次 PG-SGA 使用培训后，对 PG-SGA 的可理解性和难度的看法是否以及如何发生变化。
在这项前瞻性评估研究中，荷兰 PG-SGA 新手营养师在接受 PG-SGA 使用的单次培训之前（T0）和之后（T1）完成了一份关于 PG-SGA 可理解性和难度的问卷。在 T0 和 T1 时，通过计算可理解性（I-CI、S-CI）和难度（I-DI、S-DI）的项目和量表指数来操作可理解性和难度的感知。项目指数为 0.78 被认为是可接受的，量表指数为 0.80 被认为是可接受的，量表指数为 0.90 被认为是优秀的。
共有 35 名参与者在 T0 和 T1 时都完成了问卷。所有与可理解性和难度相关的项目指数都有所提高，尽管与食物摄入和体检相关的项目的 I-DI 仍低于 0.78。PG-SGA 难度和可理解性的量表指数从 T0 的不可接受（S-CI=0.69；S-DI=0.57）显著变化（P<0.001），在 T1 时达到优秀的可理解性（S-CI=0.95）和可接受的难度（S-DI=0.86）。
本研究的结果表明，通过提供为期一天的 PG-SGA 使用培训，可以快速提高 PG-SGA 新手营养师对 PG-SGA 的可理解性和难度的感知。
