Validation and psychometric properties of the persian version of the caregiver contribution to self-care of chronic illness inventory: a confirmatory factor analysis.
Article in BMC nursing, 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
backgroundChronic illness management requires self-care. Although family caregivers are essential in helping patients, there is currently no approved tool in Iran to assess their impact. Translating and assessing the psychometric qualities of the Caregiver Contribution to Self-Care of Chronic Illness Inventory (CC-SC-CII) in Persian was the goal of this work.
methodsConvenience sampling was used to choose 334 family caregivers of patients with chronic illnesses for this methodological study, which was carried out in Zanjan, Iran. In accordance with Beaton’s recommendations, the forward-backward approach was used to translate the instrument. Confirmatory Factor Analysis (CFA) was used to evaluate construct validity. Cronbach’s alpha for internal consistency and the Intraclass Correlation Coefficient (ICC) for test-retest stability were used to assess reliability.
resultsSelf-care maintenance, self-care monitoring, self-care management, and caregiver self-efficacy were the four initial factors that the CFA endorsed. Acceptable goodness-of-fit indices were shown by the model (χ²/df = 2.8, RMSEA = 0.07, CFI = 0.98, GFI = 0.90). Excellent internal consistency (Cronbach’s alpha = 0.96) and stability (ICC = 0.96, p < 0.001) were demonstrated by the instrument. On a standardized 0–100 scale, caregivers reported poor mean scores for self-efficacy (26.32) and self-care management (29.41).
conclusionWith low management and self-efficacy ratings, the Persian CC-SC-CII is a valid and reliable tool that may be used for clinical screening and research. Clinicians should use this measure to identify caregivers who need specific educational interventions about symptom response. CLINICAL TRIAL NUMBER: Not applicable.
