Outcome measures
Primary outcome
The primary study parameters are the non-verbal characteristics of speech
analysed by SPRAAK software developed by the University of Amsterdam.
Secondary outcome
There are no secundary study parameters or outcome parameters in this study.
Background summary
It has long been known that people with schizophrenia and people with an
autistic spectrum disorder have speech peculiarities. This phenomenon has been
described in the context of schizophrenia (Bleuler) and autism (Kanner,
Asperger). Within the common paradigma the etiology of both disorders is
different. Autism has a stronger genetic component than schizophrenia which can
be diagnosed from an age of 18, whereas autism may be diagnosed in very young
children.
This gives rise to the hypothesis that autism influences the speech development
because of the age at which autism influences the development as a whole (at a
pre-verbal age).
Study objective
This study aims to investigate the possible differences in speech
characteristics of people with schizophrenia and autism, compared to people
without a psychiatric diagnosis. Also, the possibility of creating a new means
of improving the differential diagnosis between schizophrenia and autism, will
be investigated.
Study design
Participants will be asked to complete three tasks which will be recorded by a
solid-state recording device and analysed by special speech characteristisc
software.
The first tasks entails repeating 10 sentences from the Reynell language test.
The second tasks is answering an open question like "what do you like to do in
the weekend?". Participants answers will be recorded for approximately one
minute.
The third (and last) tasks consists of describing the "Cookie theft" picture.
The second part of the study design entails asking a group of psychiatrists and
psychologists to listen to the recordings (which will be made unintelligeable)
and try to make the distinction between the participants with schizophrenia,
autism and the controlgroup.
Study burden and risks
The nature and extent of the burden and risks for the participants are very
small. There is no intervention in the treatment, nor will the treatment be
influenced by the study. Participants will be asked to complete a single
measurement as described above.
