At the end of January 2022, we published a new study in the Journal of Speech, Language and Hearing Research following an exciting collaboration between University College London (UCL) and the Western Norway University of Applied Sciences. The study systematically reviewed the literature and analysed findings from 11 studies that had compared anxiety and depression symptoms in children and adolescents (2-18 years) who do and do not stutter.
This project has been a little while in the making – starting when
Dr Hilde Hofslundsengen joined UCL as a visiting researcher at the end of 2018!
I was last invited to contribute
to this blog after my stay with Hilde in
Sogndal in May 2019, so I was delighted to be asked to share the study findings
now our article has been published!
There were several take-home findings from this meta-analysis that
we hope will inform clinical practice, future research and benefit young people
who stutter.
Firstly, although there was substantial variation in reported
anxiety symptoms across studies, overall, children and adolescents who stutter
report higher anxiety symptoms than peers. At first glance this may not seem
that surprising given the elevated risk for anxiety and social anxiety disorder
reported in adults who stutter. But the high variability across studies is noteworthy.
Secondly, the high variability in outcomes mean that not all young
people who stutter experience anxiety. We suggest that elevated anxiety may
reflect other risk factors such as exposure to bullying, access to therapy, or
family history of anxiety and depression, which may increase risk or resilience
in children and adolescents who stutter. Unfortunately, few studies reported
these additional variables, so it is currently unclear what factors contribute
to this increased risk.
Thirdly, there were too few studies investigating depression to reliably
comment on risk in young people who stutter. This highlights the need for more
research, especially given the co-occurrence of anxiety and depression in the
general population.
However, our findings do indicate the need to carefully monitor
the mental health and well-being of children and adolescents who stutter.
Ideally, in future, longitudinal studies that follow large groups of children
who stutter over time would help us understand the association between stuttering
and anxiety over the course of development.

It’s been an amazing experience collaborating with Hilde and
Professor Norbury on this study, and I look forward to working together again
soon!
