OP69 EuroQol Health And Wellbeing Short Version Validation In A Brazilian Social Program - Psychometric Properties And Applicability In Vulnerable Populations

Q: What was the main objective of the EQ-HWB-S study?

To evaluate the psychometric properties of the EQ-HWB-S questionnaire, including convergent validity and test-retest reliability, in a Brazilian social program supporting vulnerable families.

Q: Which instruments were used to assess convergent validity?

The study used the EQ-HWB-S interviews alongside EuroQol-5D and the Warwick-Edinburgh Mental Wellbeing Scale (WEMWBS) to evaluate convergent validity.

The study evaluates the psychometric performance of the EuroQol Health and Wellbeing Short Version (EQ-HWB-S) questionnaire in a Brazilian social program supporting vulnerable families with chronically ill children. Using 99 participants from Instituto Dara, the research tests convergent validity by comparing EQ-HWB-S with the EuroQol-5D and WEMWBS through face-to-face interviews, and assesses test-retest reliability in 45 participants over two weeks. Results show moderate agreement and meaningful correlations, supporting its use in vulnerable populations.

OP69 EuroQol Health And Wellbeing Short Version Validation In A Brazilian Social Program: Psychometric Properties And Applicability In Vulnerable Populations Ana Helena Santos, Andréa Monteiro, Marisa Santos ([marisaccih@gmail.com](marisaccih@gmail.com)), José Evangelista and Daniel Gigliotti Introduction: Instituto Dara, a Brazilian non-profit organization, supports vulnerable families through multidimensional interventions addressing poverty and chronic illness. While validated qualityof-life instruments are essential for program evaluation, few target disadvantaged populations with chronically ill children in Brazil. This study evaluated the psychometric properties of the EuroQol Health and Wellbeing Short Version (EQ-HWB-S) questionnaire, including its convergent validity and test-retest reliability. Methods: The study included 99 individuals representing families supported by Instituto Dara. Data collection used face-to-face interviews with EQ-HWB-S and additional validated instruments (EuroQol-5D and the Warwick-Edinburgh Mental Wellbeing Scale [WEMWBS]) to assess convergent validity. Test-retest reliability was assessed in 45 participants over a two-week period. Statistical analyses included descriptive methods and correlation analyses to summarize EQ-HWB-S applicability and performance in this population. Results: Physical domains (mobility and activities) showed minimal impairment, with most participants at level one (>75%) . In contrast, psychosocial domains showed significant burden: over 50 percent reported moderate to extreme levels of exhaustion, loneliness, and anxiety or depression. Test-retest reliability showed moderate agreement (r=0.568; p<0.001). The EQ-HWB-S yielded an overall score of 0.707. Construct validity analyses demonstrated moderate correlations with established measures (r=0.33 to 0.45), particularly with the physical well-being domains of the EQ-5D and alignment with the WEMWBS for psychological dimensions. Conclusions: The results highlighted the significance of EQ-HWB-Sin assessing domains such as loneliness, exhaustion, and control. The instrument demonstrated robust psychometric properties with moderate test-retest reliability and strong convergent validity, though its discriminatory ability warrants further investigation. These findings support its use for assessing quality-of-life outcomes in vulnerable populations with chronically ill children. OP71 Treatment Patterns, Health Resource Utilization, And Costs Of Patients With Diffuse Large B-Cell Lymphoma: A Real-World Analysis Jorge Daza, Virginia Abello, Natalia Sánchez, Jorge Ceballos, Paola Omaña, Carlos Gómez, Daniel Samacá ([daniel.samaca@roche.com](daniel.samaca@roche.com)), Andrés F. Cardona and Sergio Beltran Introduction: Diffuse large B-cell lymphoma (DLBCL) is the most common hematological neoplasm in adults globally and in Colombia, but there are limited data on its local economic impact. This study analyzed the relationship between clinical variables and healthcare resource utilization of patients with DLBCL in a Colombian health maintenance organization. Methods: This analytical observational study included patients with histopathologically confirmed DLBCL treated at the Luis Carlos Sarmiento Angulo Cancer Treatment and Research Center (CTIC) between July 2022 and September 2025 . We reported an interim analysis with a data cut-off in July 2024 . Clinical data from CTIC’s institutional registry were merged with the information provided by the administrative database, covering healthcare resource use and costs for drugs, procedures, and medical supplies. A multivariate linear regression estimated the effect of prognosis (revised International Prognostic Index [R-IPI] score) on total costs, adjusting for confounding (e.g., sex, comorbidities, and history of neoplasm) . Results: Sixty-two patients were included (mean 66 years [standard deviation 14]; 58% men) . R-IPI scores at baseline indicated that 34 percent
