“…The instrument is more than 35 years old and has been studied in several countries (e.g. Bradley, Corwyn, & Whitesid-Mansell, 1996;Cruz, Abreu-Lima, Barros, Costa, & Pacheco, 2011;Glad, Jergeby, Gustafsson, & Sonnander, 2012;Goemans, van Geel, Vedder, & Bradley, 2014), however, in 2003 all the versions of the instrument were reformulated and standardized, with validity and reliability studies being performed. The instrument is available for clinical use and for research and is currently considered the world reference in the evaluation of the family environment (Caldwell & Bradley, 2003).…”
