    <jats:p>ABSTRACT Objectives: To evaluate the internal consistency and construct validity of the QLQ-MY20 for assessing the quality of life in multiple myeloma survivors in Chile. Methods: This was a cross-sectional study conducted between March 2020 and December 2022. It involved 118 individuals from two public hospitals. The QLQ-C30 and QLQ-MY20 questionnaires were used. Internal consistency was assessed using Cronbach’s alpha(α), and construct validity was evaluated through hypothesis testing (Mann-Whitney and Spearman correlation). Results: The average age of participants was 67.2 years (SD=9.2). Internal consistency for the complete scale was α=0.779, for the “disease symptoms” dimension α=0.671, for the “side effects of treatments” dimension α=0.538, and for the “future perspective” dimension α=0.670. Four of the five construct validity hypotheses were confirmed: women, individuals with worse performance status, those with pain, and those with worse fatigue showed more symptoms. Conclusions: The Chilean version of the QLQ-MY20 demonstrates adequate internal consistency and construct validity.</jats:p>

    <jats:p>IntroducciĂłn: Personas con cáncer colorrectal (CCR) pueden presentar efectos adversos, perjudicando la calidad de vida relacionada a la salud (CVRS).Objetivo: Validar el mĂłdulo QLQ CR2-9 para evaluaciĂłn de la CVRS, en Chile. Materiales y mĂ©todo: Estudio transversal que incluyĂł 170 personas con CCR. Se analizaron la consistencia interna y validez de constructo del instrumento con test de hipĂłtesis.Resultados: 117 personas (68,8%) fueron evaluadas antes de la cirugĂ­a y 53 (31,2%) despuĂ©s de la cirugĂ­a. La consistencia interna del QLQ CR-29 fue α=0,838. Fueron comprobadas las hipĂłtesis planteadas: Los pacientes evaluados antes de la cirugĂ­a se quejaron más de “sangre/mucosidad en las heces”, “dolor abdominal”, “pĂ©rdida de cabello” e “hinchazĂłn abdominal”, mientras que los pacientes evaluados despuĂ©s presentaron más “incontinencia fecal” (p&lt;0,05). Antes de la cirugĂ­a, los pacientes con CCR presentaron mayores valores de “frecuencia urinaria”, “frecuencia de deposiciones”, “dolor en las nalgas”, “problemas con el gusto” y “vergĂĽenza”; mientras que aquellos con cáncer de colon que se quejaban más de “sangre/mucosidad en las heces” (p&lt;0,05). DespuĂ©s de la cirugĂ­a, los pacientes con cáncer de recto tenĂ­an mayor “frecuencia de deposiciones”, “eliminaciĂłn de gases” y “vergĂĽenza” (p=0,004) en comparaciĂłn con los con cáncer de colon (p&lt;0,05). Los pacientes ostomizados presentaron más “incontinencia fecal” y “vergĂĽenza” (p&lt;0,001). Fueron observadas correlaciones positivas y negativas bajas entre la mayorĂ­a de las dimensiones del QLQ C-29 con las dimensiones del QLQ C-30. ConclusiĂłn: La versiĂłn chilena del mĂłdulo QLQ CR-29 es adecuada para evaluar la CVRS en personas con CCR. </jats:p>

    <jats:title>Abstract</jats:title><jats:sec> <jats:title>Purpose</jats:title> <jats:p>Bowel complaints are very common among patients with colorectal cancer. However, the most used questionnaires for colorectal cancer survivors do not comprehensively comprise bowel symptoms. This study aimed to examine construct and criterion validity, as well as internal consistency, of the Chilean Version of the International Consultation on Incontinence Questionnaire Bowel Module (ICIQ-B) among people with colorectal cancer.</jats:p> </jats:sec><jats:sec> <jats:title>Methods</jats:title> <jats:p>Cross-sectional, validation study performed with 106 colorectal cancer patients from Hospital del Salvador, Chile. Bowel function was assessed with the ICIQ-B. Construct validity was assessed with confirmatory factor analysis and hypothesis testing. Specific items of a quality-of-life questionnaire (EORTC QLQ-CR29) were used to correlate with similar ICIQ-B items for criterion validity. For internal consistency, Cronbach’s alpha was computed.</jats:p> </jats:sec><jats:sec> <jats:title>Results</jats:title> <jats:p>For construct validity, the confirmatory factor analysis showed that the three factors model did not fit our data. Meanwhile, hypothesis testing favored the construct validity of the instrument, considering that rectal cancer patients showed worse bowel pattern (p = 0.001), bowel control (p = 0.001) and quality of life (p &lt; 0.001) scores compared to colon cancer patients. In addition, those patients assessed before surgery also presented worse scores bowel control (p = 0.023) and quality of life (p = 0.009) compared to post-surgical patients. Regarding criterion validity, the ICIQ-B items showed a significant correlation with similar QLQ-CR29 items. The internal reliability of the instrument was good (Cronbach’s α = 0.909).</jats:p> </jats:sec><jats:sec> <jats:title>Conclusion</jats:title> <jats:p>Considering that this questionnaire appraises bowel function in more depth, it is recommended for use in clinical practice and research with colorectal cancer patients.</jats:p> </jats:sec>
