“…In line with this, breastfeeding is predicted by attitude (Manstead, Proffitt, & Smart, 1983), subjective norm (Bai, Wunderlich, & Fly, 2011), perceived control (Dodgson, Henly, Duckett, & Tarrant, 2003;McMillan et al, 2008), and self-efficacy (Blyth, Creedy, Dennis, Moyle, Pratt, & De Vries, 2002;de Jager, Broadbent, Fuller-Tyszkiewicz, Nagle, McPhie, & Skouteris, 2015;de Jager, Broadbent, Fuller-Tyszkiewicz, & Skouteris, 2014). Moreover, interventions based on these social-cognitive factors have been found to increase breastfeeding intentions (Giles et al, 2014). This suggests that the social-cognitive factors proposed by the theory of planned behavior and extensions of this model (i.e., self-efficacy) are likely to predict exclusive breastfeeding.…”
