Children acquire the skills to monitor the adequacy of their spoken message and to self-initiate repair strategies that modify the message during early, middle, and late childhood. To characterize further the communication deficits of childhood-onset schizophrenia, this study compared self-initiated repair strategies in schizophrenic and normal children and their relationship with formal thought disorder, discourse deficits, and distractibility.
Measures of self-initiated repair, formal thought disorder, and cohesion were coded in 32 schizophrenic and 47 normal children, aged 5.6 to 12.4 years, from speech samples elicited with the Story Game.
The schizophrenic children used some repair strategies (false starts, fillers, referential revision) more infrequently than the normal children. Within the schizophrenic group, the children who were receiving neuroleptic medication underutilized repair and had more discourse deficits than the unmedicated patients. Loose associations and distractibility were associated with increased use of false starts but not fillers.
In addition to formal thought disorder and discourse deficits, schizophrenic children underutilize self-initiated repair when presenting their thoughts to the listener, particularly if they are being treated with neuroleptics, a potential sign of increased clinical morbidity. Impoverished communication skills might reflect negative signs in childhood-onset schizophrenia.
