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). Methods: 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. Results: 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. Conclusions: 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.

Uit de conclusie van het proefschrift : " De centrale vraag is opgedeeld in vier onderzoeksvragen. Aan de hand van deze onderzoeksvragen wordt een antwoord op de centrale vraag gegeven. 1 Wat zijn de principes van de Stichting Architecten Research (SAR) en gerelateerde concepten en welke aspecten zijn hieruit af te leiden om de toekomstbestendigheid van renovatieconcepten te beoordelen? 2 Welke overige factoren zijn van invloed op de toekomstbestendigheid van renovatieconcepten en welke aspecten zijn hieruit af te leiden om de toekomstbestendigheid van renovatieconcepten te beoordelen? 3 Welke renovatieconcepten worden er anno 2015 in Nederland aangeboden? 4 Op welke wijze voldoen de renovatieconcepten aan de aspecten die bepalend zijn voor de toekomstbestendigheid? Dit onderzoek is een evaluerend onderzoek naar 25 renovatieconcepten. Het doet geen aanbevelingen aan de conceptontwikkelaars. De 25 aangedragen concepten moeten verder onderzocht worden om de toepasbaarheid van elk van de aspecten nauwkeuriger te beschrijven en gerichter van aanbevelingen te kunnen voorzien. Zo is verder onderzoek naar de aanpasbaarheid van de installaties in combinatie met de verwachte klimatologische veranderingen een onderzoeksgebied. "
