Anxiety disorders are the most common mental health problems among children (e.g., Costello et al., 2005; Polanczyk et al., 2015). Children with anxiety disorders experience impairment across academic, family, and social domains, and report lower life satisfaction compared with children without anxiety disorders (Swan & Kendall, 2016). Among the anxiety disorders, separation anxiety disorder is the most common for children under 12 years of age (American Psychiatric Association, 2013). Separation anxiety disorder is characterized by excessive and impairing concerns about being separated from attachment figures or home (American Psychiatric Association, 2013). Early in life, some anxiety upon separation from attachment figures is developmentally appropriate and evolutionarily adaptive (Feriante et al., 2023). In 4% of children, however, excessive separation anxiety persists into childhood and becomes impairing (Copeland et al., 2014; Shear et al., 2006). Symptoms present in a myriad of ways, including distress and/or physical symptoms upon separation, excessive concern that harm will befall their attachment figure or themselves when separated, refusal to sleep alone, and refusal to attend school, which contribute to significant impairment for the child and family (American Psychiatric Association, 2013).
Family Accommodation
Children, like all mammals, are born ill-prepared for independent life and thus, rely on their parents for many aspects of survival, including safety when experiencing threat. When young children feel scared, they exhibit fear cues that alert their attachment figures to respond by providing protection, regulation, and comfort (Bowlby, 1973; 1982). This social aspect of the immature anxiety response is typically adaptive. However, among children with anxiety disorders, who experience chronic overactivation of their threat detection systems, there is overactivation of the social signaling of fear, which leads parents to implement extensive accommodations for their child’s anxiety (Lebowitz et al., 2013).
Family accommodation of child anxiety refers to changes in parental behavior aimed at avoiding or alleviating child anxiety-related distress (Lebowitz et al., 2013). Family accommodation is exceedingly common among parents of children with anxiety disorders, with an estimated 95–100% of parents reporting some degree of family accommodation (Benito et al., 2015; Lebowitz et al., 2013; Shimshoni et al., 2019; Thompson-Hollands et al., 2014). Accommodation for separation anxiety, particularly by parents, takes many forms, such as allowing a child to sleep in their bed, avoiding leaving the child with a babysitter or relative, and remaining present at playdates or birthday parties (Thompson-Hollands et al., 2014). Although well-intentioned, family accommodation plays a role in maintaining, rather than diminishing, child anxiety over time (Lebowitz et al., 2013). When parents accommodate a child’s anxiety, they unintentionally communicate that the child is unable to handle fear independently (Lebowitz et al., 2013; Norman et al., 2015; Shimshoni et al., 2019). This message increases child avoidance of anxiety-provoking stimuli, which contributes to more severe impairment in a child’s life (Swan & Kendall, 2016). Extensive empirical evidence supports this conceptual model whereby the degree of family accommodation is positively correlated with anxiety symptom severity and impairment (Benito et al., 2015; de Barros et al., 2020; Kagan et al., 2016; 2017; La Buissonnière-Ariza et al., 2018; Lebowitz et al., 2013; Lebowitz et al., 2014; Storch et al., 2015; Thompson-Holland et al., 2014).
Family Accommodation in Youth Separation Anxiety
Although family accommodation is prevalent across all anxiety disorders, studies have reported particularly high levels of family accommodation for separation anxiety symptoms (La Buissonnière-Ariza et al., 2018; Lebowitz et al., 2013; Storch et al., 2015; Thompson-Holland et al., 2014). Lebowitz and colleagues (2016) found biological evidence in support of this association, showing that salivary oxytocin levels in anxious children were significantly associated with degree of family accommodation and were most strongly associated with separation anxiety symptoms compared with other anxiety symptoms. Parents may be more willing to accommodate separation anxiety as their child’s desire for closeness with them may be viewed more positively than accommodations of other types of anxiety (Storch et al., 2015). The strong association between family accommodation and separation anxiety symptoms is also unsurprising given that separation anxiety is inherently related to the presence and behavior of attachment figures.
Moderation of Family Accommodation and Youth Anxiety
As summarized above, family accommodation plays a key role in the course of child anxiety, but relatively little is known about factors that predict for which children accommodation may be particularly impactful. Several variables have been found though, that moderate the association between family accommodation levels and overall child anxiety symptoms. Settipani and Kendall (2017) found maternal anxiety and maternal empathy significantly moderated the link between child anxiety distress and family accommodation in clinically anxious youth (N = 70, 7-17 yrs). Schleider and colleagues (2018) found family accommodation was significantly associated with anxiety symptom severity in clinically anxious children with low anxiety sensitivity, but not children with high anxiety sensitivity (N = 103, 6-17 yrs).
The Role of Child-Parent Attachment
The particularly strong association between family accommodation and separation anxiety symptoms relative to other anxiety symptom subtypes suggests there may be unique moderators of this association. In considering separation anxiety, one variable that may moderate family accommodation is child attachment security. As theorized by Bowlby and illustrated by Mary Ainsworth in the seminal “strange situation” paradigm, securely attached children separate more easily and with less anxiety compared with insecurely attached children and recover more quickly than insecurely attached children upon reunification with their caregiver (Ainsworth, 1979; 1989). The positive internal working model of the caregiver as a “secure base” provides the basis for secure separation, without fear of abandonment (Ainsworth, 1979; 1989; Bowlby, 1973; 1982). Given that children differ in their ability to separate from their caregivers based on their attachment style, attachment security may play a more significant role for separation anxiety symptoms than for other anxiety symptom subtypes. In line with this theory, insecure attachment is associated with separation anxiety symptoms and insecure infant attachment predicts separation anxiety symptoms at age six (Brumarui & Kerns, 2010; Dallaire & Weinraub, 2005; Mofrad et al., 2010).
Family accommodation’s impact on separation anxiety may also vary based on a child’s attachment security, much like a child’s response to reunification in the strange situation varies based on attachment style. For example, in less securely attached children, a parents’ accommodation could serve to reinforce internalized feelings of vulnerability in a hostile and untrustworthy world, leading to more severe anxiety (Blandin et al., 1994). In more securely attached children, the parents’ accommodation may be less likely to exacerbate anxiety severity as it could be perceived as part of the internalized secure base the parent provides (De Wolff & Ijzendoorn, 1997; Koehn & Kerns, 2018; Nievar & Becker, 2008). No studies have yet to examine the potential interactions between family accommodation and attachment security in relation to child separation anxiety symptoms.
Present Study
Family accommodation has been identified as an important factor in maintaining anxiety and is particularly strongly associated with symptoms of separation anxiety. Although both family accommodation and separation anxiety concern the child-parent attachment relationship, this study is the first to examine child attachment within the context of these two constructs. Understanding the role of child attachment security within this well-established association helps advance our conceptualization of separation anxiety and our understanding of for which children family accommodation is most important. The goal of the present study was to examine how child attachment security moderates the association between family accommodation and separation anxiety symptoms, and to determine whether this moderation effect is specific to separation anxiety symptoms among other anxiety symptom subtypes and overall anxiety symptoms. Family accommodation was hypothesized to be more strongly associated with separation anxiety symptoms in children with lower attachment security than children with higher attachment security.
