“…Specifically, factor analytic techniques have been used to identify the number of latent factors that underlie covariation among the AAI attachment state of mind ratings and the degree to which specific rating scales load on the various latent variables (see Haltigan, Roisman, & Haydon, 2014, for an overview of research on the factor structure of the AAI). The factor analytic results from over 10 separate samples have provided robust evidence that the variation in the AAI ratings of individuals’ attachment states of mind is accounted for by two latent variables: one reflecting individuals’ dismissing states of mind and the other reflecting individuals’ preoccupied states of mind (Bernier, Larose, Boivin, & Soucy, 2004; Haltigan, Leerkes, Supple, & Calkins, 2014; Haltigan, Roisman, et al, 2014; Larose & Bernier, 2001; Macfie, Swan, Fitzpatrick, Watkins, & Rivas, 2014; Martin et al, 2017 [this issue]; Raby, Labella, Martin, Carlson, & Roisman, 2017 [this issue]; Roisman et al, 2007; Scharf, Mayseless, & Kivenson-Baron, 2012; Whipple, Bernier, & Mageau, 2011). …”
