Validation of the Pearlin Mastery Scale for unpaid caregivers of people living with dementia in Brazil: a methodological study.

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
backgroundSense of mastery has been described in the literature as a psychological resource potentially associated with reduced caregiver burden. However, there are no validated instruments in the Brazilian context that allow the evaluation of the sense of mastery as a possible outcome of interventions aimed at supporting unpaid caregivers of people with dementia.
objectiveTo validate the construct of the Brazilian version of the Pearlin Mastery Scale among unpaid caregivers of people living with dementia. DESIGN AND
settingThis methodological study was conducted with 100 unpaid caregivers of people living with dementia, cared for at home, and who resided in Brazil.
methodsEvidence of validity was tested based on internal structure, reliability, and correlations with theoretically related constructs. Sociodemographic data on sense of mastery, burden, depressive symptoms, anxiety, and quality of life were collected.
resultsDifficulties involving burden (80%), depressive symptoms (70%), anxiety (65%), and low quality of life (62%) were reported. Satisfactory measures of adjustment were found in the factor analysis; however, by removing two inversely scored items, these measures improved, resulting in a Cronbach's alpha of 0.75. Significant correlations were found between sense of mastery and burden scores (ρ = -.56), symptoms of depression (ρ = -.57), anxiety (ρ = -.57), and quality of life (ρ = .64).
conclusionEvidence of validity was found for the Pearlin Mastery Scale Brazilian version based on the internal structure, reliability, and correlations with theoretically related constructs, indicating that it is a suitable instrument for use in Brazil.
