Development and validation of the Bush-Francis Catatonia Rating Scale – Brazilian version

Desenvolvimento e validação da versão brasileira da escala de classificação de Bush-Francis para catatonia

Authorship SCIMAGO INSTITUTIONS RANKINGS

ABSTRACT

Objective:

This article aims to describe the adaptation and translation process of the Bush-Francis Catatonia Rating Scale (BFCRS) and its reduced version, the Bush-Francis Catatonia Screening Instrument (BFCSI) for Brazilian Portuguese, as well as its validation.

Methods:

Semantic equivalence processes included four steps: translation, back translation, evaluation of semantic equivalence and a pilot-study. Validation consisted of simultaneous applications of the instrument in Portuguese by two examiners in 30 catatonic and 30 non-catatonic patients.

Results:

Total scores averaged 20.07 for the complete scale and 7.80 for its reduced version among catatonic patients, compared with 0.47 and 0.20 among non-catatonic patients, respectively. Overall values of inter-rater reliability of the instruments were 0.97 for the BFCSI and 0.96 for the BFCRS.

Conclusion:

The scale's version in Portuguese proved to be valid and was able to distinguish between catatonic and non-catatonic patients. It was also reliable, with inter-evaluator reliability indexes as high as those of the original instrument.

Item	Original Version	Translation	Back translation	Summary	Comments
	5. Posturing/catalepsy:	5.A. Postura/Catalepsia	5.A. Posture / Catalepsy	5. Postura/Catalepsia:
	Spontaneous maintenance of posture(s), including mundane (e.g. sitting or standing for long periods without reacting).	Manutenção espontânea de postura(s), incluindo usuais (ex. permanecer sentado ou de pé por longos períodos sem reaçáo).	Maintenance of spontaneous posture (s), including the usual (eg sit or stand for long periods without reaction).	Manutenção espontânea de postura(s), inclusive comum(ns) (ex. permanecer sentado ou de pé por longos períodos sem reaçáo).
	0 = Absent.	0 = Ausente	0 = Absent	0 = Ausente	No disagreement regarding term translation. Regarding term definition, we preferred to translate “mundane” as “usual” since the term in the original language means ordinary. The translation into Portuguese - “mundano” - could eventually mean “someone seduced by material pleasures” or “belonging to the world,” the latter as something material and transitory.
	1 = Less than 1 min.	1 = Menos de 1 minuto.	1 = Less than 1 minute.	1 = Menos que 1 minuto.
	2 = Greater than one minute, less than 15 min.	2 = Mais de 1 minutos, menos de 15 minutos.	2 = More than 1 minute, less than 15 minutes.	2 = Mais de 1 minuto, menos de 15 minutos.
5	3 = Bizarre posture, or mundane maintained more than 15 min.	3 = Postura bizarra, ou usual mantida por mais de 15 minutos.	3 = bizarre posture, or usual held by more than 15 minutes.	3 = Postura bizarra ou corriqueira mantida por mais de 15 minutos.

	18. Gegenhalten:	18.A. Gegenhalten/paratonia	18.A. Gegenhalten / paratony	18. Gegenhalten (Paratonia inibitoria):
	Resistance to passive movement, which is proportional to strength of the stimulus, appears automatic rather than wilful.	Resistência ao movimento passivo que é proporcional à força do estímulo, aparentemente automatico e não intencional.	Resistance to passive movement that is proportional to the strength of the stimulus, apparently automatic and unintentional.	Resistência ao movimento passivo que e proporcional a força do estímulo, aparentemente automática e não intencional.
	0 = Absent.	0 = Ausente.	0 = Absent.	0 = Ausente.	“Gegenhalten” is a German word and has no translation in Portuguese. We considered translator 1's version closer to the original.
	3 = Present.	3 = Presente.	3 = Present.	3 = Presente.
