The German 12-Item Brief Form of the Cancer Behavior Inventory (CBI-B-D-12): Factor Structure, Reliability, and Criterion Validity.
Article in Psycho-oncology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundThe Cancer Behavior Inventory Brief Form (CBI-B) allows assessing self-efficacy for coping with cancer as a personal resource of patients facing a diagnosis of cancer and its treatment. While psychometric analyses of CBI-B versions in other languages than English exist, the German version has not been analyzed more thoroughly in this respect yet.
aimsAgainst this background, we analyzed the factor structure, internal consistency, and criterion validity of the German 12-item version of the Cancer Behavior Inventory Brief Form, the CBI-B-D-12.
methodsBased on a pooled sample of N = 1034 cancer patients from various settings, we performed confirmative factor analyses, computed Cronbach's α and McDonald's ω for the 12-item summary scale, and determined criterion correlations with measures of patients' health-related quality of life, anxiety, depression, fear of progression, and fatigue.
resultsWith few adjustments, confirmative factor analysis revealed good fit of a 4-factor model identifying the same dimensions of coping self-efficacy as the original instrument (Maintaining Independence and Positive Attitude, Participating in Medical Care, Coping and Stress Management, and Managing Affect). With values of Cronbach's α and McDonald's ω being 0.89 and 0.88 respectively, estimates of the scale's internal consistency were good, and criterion correlations further supported its validity.
conclusionsThe German 12-item version of the CBI-B represents a reliable measure of cancer patients' self-efficacy for coping with cancer that is valid in terms of factorial structure and correlations with major distress and quality of life criteria. It may thus be used in clinical practice and psycho-oncological research.
