“…The instrument was validated observing parenting behavior and child misbehavior, distinguishing between mothers of children in clinical and non-clinical populations (Arnold et al, 1993). Since the publication of the PS, several studies have examined its dimensionality using exploratory and confirmatory approaches (Arney et al, 2008;Collett et al, 2001;Del Vecchio, Jerusalmi, & Terjesen, 2017;Harvey et al, 2001;Irvine et al, 1999;Karazsia et al, 2008;Kliem et al, 2019;Prinzie et al, 2007;Reitman et al, 2001;Rhoades & O'Leary, 2007;Salari et al, 2012;Steele et al, 2005). However, only Arney et al (2008) identified a factor structure that was similar to the original one reported by Arnold et al (1993), and even then they reported low internal consistency and test-retest reliability for verbosity.…”
