Understanding the prevalence and manifestation of anxiety and other socio-emotional and behavioural difficulties in children with Developmental Language Disorder

Abstract Background It is well-documented that children with Developmental Language Disorder (DLD) have a higher likelihood of experiencing anxiety, as well as other socio-emotional and behavioural (SEB) difficulties. Despite this, there is little consensus as to how these difficulties manifest. This study aims to understand the prevalence of broader SEB difficulties and anxiety, informing intervention development by understanding the relationships between them. Methods A mixed-methods, case–control study was conducted. First, an online survey was completed by 107 parents of either children with DLD (“DLD sample”; n = 57) or typically developing children (“typical sample”; n = 50), aged 6–12 years old. Binary SEB statements informed by previous qualitative work (e.g. “my child requires routine/sameness”; “my child has frequent tantrums”) provided an insight into the prevalence of SEB difficulties in both DLD and typical samples. Validated measures of anxiety, emotion regulation, intolerance of uncertainty, insistence on sameness, family stress and coping mechanisms were also collected. Correlation and mediation analyses were run using these validated measures to understand the manifestation of anxiety in children with DLD in more detail. Qualitative interviews were then carried out with a select panel of survey respondents (n = 4). Results The DLD sample scored significantly higher on all binary SEB statements than the typical sample: experiencing anxiety (80.7%, p
