The validity and reliability of the Swedish CancerSupportSource-Caregiver: a screening tool for psychological distress and support needs in clinical cancer care.
Article in Journal of cancer research and clinical oncology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundTimely, individually tailored support for family caregivers of cancer patients is stressed, reinforcing the importance of implementing screening tools in clinical practice.
aimThis study aims to evaluate the validity and reliability of the Swedish CancerSupportSource-Caregiver among 145 Swedish family caregivers of persons diagnosed with cancer.
methodsWe evaluated the validity and reliability of the Swedish CancerSupportSource-Caregiver among 145 Swedish family caregivers of persons diagnosed with cancer who responded to the Swedish CancerSupportSource-Caregiver, sociodemographic questions, and the Hospital Anxiety and Depression Scale. Psychometric analyses were performed using descriptive statistics and classical test theory to evaluate data quality, targeting, scaling assumptions, and internal validity. Construct validity was assessed through confirmatory factor analysis; criterion validity through concurrent validity; and reliability through internal consistency.
resultOverall, in the sample, evaluations demonstrated generally satisfactory psychometric properties with respect to data quality, targeting, and scaling assumptions. The hypothesized five-domain model showed an acceptable fit to the data, although there were indices that it could be improved. Item loadings were generally high, supporting the proposed construct structure. Further, assessments of the criterion validity were satisfactory. However, the evaluations of internal validity and internal consistency indicated redundancy, mainly within the emotional well-being domain.
conclusionThe Swedish CancerSupportSource-Caregiver demonstrated preliminary satisfactory abilities to screen for support needs and psychological distress among Swedish family caregivers of persons diagnosed with cancer. Further evaluations in larger samples, using Rasch measurement theory, could provide a deeper understanding of the functioning of items and response options.
