Interactions between parenting styles, child anxiety, and oppositionality in selective mutism.

Selective mutism (SM) is a poorly understood condition, and debate continues regarding its etiology and classification. Research suggests that a genetic vulnerability may play a role in the development of the disorder which may be compounded by anxious and over-protective parenting. While previous studies supported the role of parenting styles in the development of SM, most of them examined child and parent factors in isolation. The current study examined how the interactions between child internalizing and externalizing behaviors (anxiety and oppositionality, respectively) and parenting styles (authoritative, permissive, and authoritarian) are associated with SM diagnosis. The study included 285 children aged 3-7 years (57.2% females), and their parents (66 children with SM and 219 typically developed children). Parents completed questionnaires about child social anxiety, oppositional behavior, SM severity, and their parenting style. Results showed that parents of children with SM reported lower levels of authoritative practices than those of typically developed children. We also found that child social anxiety and oppositionality moderated the effects of authoritative and authoritarian parenting practices on SM diagnosis. Our results suggest that child anxiety and oppositionality may explain the different susceptibility of children to adaptive and maladaptive parenting styles.

Selective mutism in immigrant families: An ecocultural perspective.

Although the diagnosis of selective mutism (SM) is more prevalent among immigrant children, the link between the disorder and an immigration background has been elusive. Guided by ecocultural models of development, the current study aimed to construct a theory-based description of SM while considering individual, family, and contextual risk factors. Participants were 78 children with SM (38.4% with an immigration background), and 247 typically developed children (18.2% with an immigration background). Consistent with previous studies, our results suggest that anxiety was the most important predictor of SM symptoms, above and beyond immigration background. Immigration, especially if coupled with bilingual status and low family income, predicted increased levels of SM symptoms. Identifying multi-level predictors of SM may help researchers and clinicians to improve early identification and treatment of SM in culturally and linguistically diverse children.
