The Patient-Generated Subjective Global Assessment (PG-SGA) is an instrument to screen, assess and monitor malnutrition and risk factors, and to triage for interventions. After having translated and culturally adapted the original PG-SGA for the Italian setting, according to International Society for Pharmacoeconomics and Outcomes Research (ISPOR) Principles, we tested linguistic validity, i.e., perceived comprehensibility and difficulty, and content validity (relevance) of the Italian version of the PG-SGA in patients with cancer and a multidisciplinary sample of healthcare professionals (HCPs).
After the translation and cultural adaptation of the original PG-SGA for the Italian setting, the patient component (i.e., PG-SGA Short Form (SF) was tested for linguistic validity (i.e., comprehensibility ad difficulty) in 120 Italian patients with cancer and 81 Italian HCPs. The full PG-SGA, i.e., patient and professional component of the PG-SGA, was tested for content validity, i.e., relevance, in 81 Italian HCPs. The data were collected by a questionnaire and evaluations were operationalized by a 4-point scale. Through item and scale indices we evaluated the comprehensibility (I-CI, S-CI), difficulty (I-DI, S-DI) and content validity (I-CVI, S-CVI). Scale indices 0.80-0.89 were considered acceptable, and scale indices ≥0.90 were considered excellent.
Patients perceived comprehensibility and difficulty of the PG-SGA SF (Boxes) as excellent (S-CI = 0.98, S-DI = 0.96). Professionals perceived comprehensibility of the professional component (Worksheets) as excellent (S-CI = 0.92), difficulty as acceptable (S-DI = 0.85), and content validity of the full PG-SGA as excellent (S-CVI = 0.92). Dietitians gave higher scores (indicating better scores) on comprehensibility, difficulty, and content validity of Worksheet 4 (physical exam) than the other professions. In Worksheet 4, four items were considered most difficult to complete and were considered below acceptable range. Relevance was perceived as excellent by professionals for both the patient component (S-CVI = 0.93) and the professional component (S-CVI = 0.90), resulting in S-CVI = 0.92 for the full PG-SGA. Slight textual modifications were implemented resulting in the final version of the Italian PG-SGA.
Translation and cultural adaptation of the original PG-SGA resulted in the Italian version of the PG-SGA that maintained its original purpose and meaning and can be completed adequately and easily by patients and professionals. The Italian PG-SGA is considered relevant for screening, assessing and monitoring malnutrition and risk factors, as well as triaging for interventions by Italian HCPs.
将原始 PG-SGA 翻译成意大利语，并根据国际药物经济学和结果研究学会（ISPOR）原则进行文化调适后，我们在意大利的癌症患者和多学科医疗保健专业人员（HCP）样本中测试了意大利语 PG-SGA 的语言有效性（即感知的理解度和难度）和内容有效性（相关性）。
对原始 PG-SGA 进行意大利语翻译和文化调适后，我们在 120 名意大利癌症患者和 81 名意大利 HCP 中测试了患者部分（即 PG-SGA 简短形式（SF））的语言有效性（即理解度和难度）。我们在 81 名意大利 HCP 中测试了完整的 PG-SGA，即 PG-SGA 的患者和专业部分的内容有效性，即相关性。数据通过问卷收集，评估通过 4 分制进行。通过项目和量表指标，我们评估了理解度（I-CI、S-CI）、难度（I-DI、S-DI）和内容有效性（I-CVI、S-CVI）。量表指数 0.80-0.89 被认为是可以接受的，而量表指数≥0.90 被认为是优秀的。
患者认为 PG-SGA SF（框）的理解度和难度非常好（S-CI=0.98，S-DI=0.96）。专业人员认为专业部分（工作表）的理解度非常好（S-CI=0.92），难度可接受（S-DI=0.85），完整 PG-SGA 的内容有效性非常好（S-CVI=0.92）。营养师在工作表 4（体检）的理解度、难度和内容有效性方面的评分（表示得分较高）高于其他专业人员。在工作表 4 中，有四个项目被认为是最难完成的，并且处于可接受范围以下。专业人员认为患者部分（S-CVI=0.93）和专业部分（S-CVI=0.90）的相关性都非常好，因此完整 PG-SGA 的 S-CVI 为 0.92。对一些文字进行了轻微修改，最终形成了意大利语 PG-SGA 的版本。
原始 PG-SGA 的翻译和文化调适产生了意大利语版本的 PG-SGA，它保持了其原始目的和意义，并且可以由患者和专业人员充分、轻松地完成。意大利语 PG-SGA 被认为与意大利的 HCP 进行筛查、评估和监测营养不良和风险因素以及干预分诊相关。
