Measuring change in perceived well-being of family caregivers: validation of the Spanish version of the Perceived Change Index (PCI-S) in Chilean dementia caregivers.
Article in International journal of geriatric psychiatry, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled it.
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
objectiveFew instruments evaluate family caregiver perceptions of challenges caring for persons with dementia and improvement or worsening in these areas. To address this measurement gap, we examine psychometric properties of a Spanish version of the 13-item Perceived Change Index (PCI-S), originally validated with English-speaking caregivers.
methodsCross-sectional study with 94 caregivers of persons with mild to moderate dementia in Chile. Interviews included caregiver demographics, burden, health perception, distress with behaviours, dementia severity, behavioural symptoms and functionality.
resultsCaregiver mean age was 55.9 (SD ± 14.14) years and mean years caregiving was 3 (SD ± 2.60). The scale had strong internal consistency (Cronbach α = 0.94), and inter-observer consistency (CCI = 0.99; 95% CI = 0.95-0.99). Two factors were identified: Management skills (α = 0.89), and somatic well-being and affects (α = 0.92), explaining 63% of scale variance. Significant associations supporting convergent validity were observed for PCI-S and subscales with caregiver burden (p < 0.01), health perceptions (p < 0.01), depressive symptoms (p < 0.01) and distress with behaviours (p < 0.01); and in persons with dementia, functionality (p < 0.05), dementia severity (p < 0.05) and behavioural symptoms (p < 0.01) in expected directions. In logistic regression models, perceived worsening (PCI-S and subscale scores) was associated with more behavioural symptoms (OR = 1.07; 95% CI = 1.03-1.15) and caregiver burden (OR = 1.48; 95% CI = 1.18-1.86); whereas perceived improvement was associated with higher physical functioning (OR = 0.95; 95% CI = 0.91-0.99) in persons with dementia. PCI-S scores were not associated with socio-demographic characteristics reflecting divergent validity.
conclusionsSpanish version of the 13-item Perceived Change Index and its two-factor solution is a valid and reliable measure with clinical utility to detect improvement or worsening in caregivers concerning daily care challenges. Copyright © 2017 John Wiley & Sons, Ltd.
