“…However, parent-child separation refers not only to a single event, but also involves multiple levels of conceptualization, such as the form of the separation (i.e., father migrating, mother migrating, or both parents migrating; Wen & Lin, 2012), the duration of the separation, as well as separation distance and location (González-Ferrer, Baizán, & Beauchemin, 2012), parent-child relationship (Jia & Tian, 2010), and frequency of parental home visits (Su et al, 2013). For example, children with two migrating parents reported a longer separation time and less frequent parental visits compared to children with one migrating parent (Su et al, 2013). Tao, Guan, Zhao, and Fan (2014) compared preschoolers with one migrating parent, two migrating parents, and no migrating parents, and found no significant differences between the three groups in terms of the mental health variables (e.g., emotional symptoms, negative characteristics, social maladjustment, peer problems, behavior problems, dietary and sleep disorders, and hyperactivity), after adjusting for demographic indicators.…”
