Purpose: The main aim of this study was to gain insight into whether temperament and/or stuttering severity were associated with anxiety and depression in children who stutter. Additionally, the study also provided an indication into the prevalence of anxiety and depression in children who stutter in a clinical cohort.

Method: The participants were 132 English-speaking children (105 boys and 27 girls) between 9;0 and 14;11 years old (M = 11;8, SD = 1;10) and their mothers. At their first visit to a specialist center for children who stutter, mothers and children completed the relevant versions of the Early Adolescent Temperament Questionnaire-Revised (EATQ-R; Ellis & Rothbart, 2001) and a screening of children's anxiety and depression, using the Revised Children's Anxiety and Depression Scale (RCADS; Chorpita et al., 2000). Stuttering was evaluated using the Stuttering Severity Instrument Fourth Edition (SSI-4). Correlations were conducted between child and parent versions of the EATQ-R and RCADS; EATQ-R and RCADS; as well as the SSI-4 and RCADS. A comparison was made between those children who scored below the clinical threshold for anxiety and depression, and those who scored above. Results: Significant correlations were found for all mother and child EATQ-R factors and RCADS scales (except for Obsessive Compulsive Disorder). Correlations were also found between the child-and mother-reported temperament factors of positive reactivity, negative reactivity, and self-regulation and anxiety and depression. Children who scored above the clinical threshold for any category of anxiety or depression had significantly lower positive reactivity and higher negative reactivity scores, compared to those who scored below the threshold. There were no differences between the two groups with regard to SSI-4 scores.

Conclusions: This is the first study to evaluate associations between temperament and anxiety and depression in children who stutter. Higher negative reactivity scores and lower positive reactivity and self-regulation scores are associated with elevated levels of anxiety and depression in children who stutter. Further, those who score above the clinical threshold have significantly higher levels of negative reactivity and lower levels of positive reactivity compared to those scoring below the threshold. Findings suggest that levels of anxiety that reach clinical threshold are more prevalent in children who stutter than would be expected based on population data. Current findings have implications for both the assessment and therapy of children who stutter presenting at clinics for support.
