Psychometric validation of the Danish cancer caregiver roles and responsibilities scale.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeThe 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.
methodsThe 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).
resultsThe 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.
conclusionThe 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.
