Cross-cultural adaptation of the Patient-Doctor Relationship Questionnaire (PDRQ-9) in Brazil.
Article in Revista de saude publica, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
objectiveTo describe the process of cross-cultural adaptation of the Patient-Doctor Relationship Questionnaire (PDRQ-9), as well as compare the agreement between two different types of application.
methodsThis is a cross-sectional study with 133 adult users of a Primary Health Service in Porto Alegre, State of Rio Grande do Sul, Brazil. The PDRQ-9 was answered by the participants as a self-administered questionnaire and in an interview. The instrument was also validated by interview, using data from 628 participants of the Mais Médicos Program Evaluation Research, which is a cross-sectional study with a systematic sample of Primary Care Services in all regions of Brazil. We evaluated the semantic, conceptual, and item equivalence, as well as factor analysis and reliability.
resultsAll items presented factor loading > 0.5 in the different methods of application and populations in the factor analysis. We found Cronbach's alpha of 0.94 in the self-administered method. We found Cronbach's alpha of 0.95 and 0.94 in the two different samples in the interview application. The use of PDRQ-9 with an interview or self-administered was considered equivalent.
conclusionsThe cross-cultural adaptation of the PDRQ-9 in Brazil replicated the factorial structure found in the original study, with high internal consistency. The instrument can be used as a new dimension in the evaluation of the quality of health care in clinical research, in the evaluation of services and public health, in health management, and in professional training. Further studies can evaluate other properties of the instrument, as well as its behavior in different populations and contexts.
