Psychometric validation of the Danish cancer caregiver roles and responsibilities scale

Purpose: The purpose of this study was to translate and culturally adapt the Caregiver Roles and Responsibilities Scale (CRRS) into Danish and to conduct a psychometric analysis of its validity and reliability among informal caregivers of cancer patients in Denmark. Methods: The translation and cultural adaptation followed the Functional Assessment of Chronic Illness Therapy (FACIT) translation methodology. Cognitive debriefing interviews were carried out with ten native Danish-speaking caregivers to assess comprehensibility and relevance. Psychometric properties were evaluated using a survey, test-retest design, with data collected from 180 caregivers at baseline (t0) and a subsample of 80 caregivers at the second time point (t1), 10 days after baseline, to evaluate test–retest reliability using Intraclass Correlation Coefficient (ICC). Results: The Danish CRRS demonstrated good psychometric properties, with Cronbach’s α values exceeding the acceptable threshold of 0.70 for most subscales, indicating high internal consistency. ICC analysis showed strong test—retest reliability across all subscales (ICC ≥ 0.80) and excellent reliability for the total CRRS score (ICC = 0.91), confirming the measure’s reliability over time. Conclusion: The Danish CRRS demonstrated good validity and test—retest reliability. The CRRS is now available for Danish-speaking individuals to use in both clinical cancer care and research for assessing the impact of cancer on the lives and wellbeing of informal caregivers.
