H. Altman et al., SUBCLINICAL HALLUCINATIONS AND DELUSIONS IN NONPSYCHOTIC ADOLESCENTS, Journal of child psychology and psychiatry and allied disciplines, 38(4), 1997, pp. 413-420
A number of studies have suggested that clinical populations of adoles
cents may report hallucinations and/or delusions without meeting crite
ria for a psychotic disorder. The purpose of this study was to provide
information about the prevalence and symptom correlates of these subc
linical hallucinations and delusions that occur in a nonpsychotic popu
lation of adolescents. Thirty-eight adolescents from a residential pro
gram and day treatment center were assessed with respect to hallucinat
ory experiences, ideas of reference, paranoid ideation, dissociative e
xperiences, depressive symptomatology, and schizotypal cognitions. Res
ults of this study indicated that 33 % of the participants reported ha
ving experienced auditory hallucinations, and 24% reported having had
delusional ideas. In addition, the results suggest that subclinical au
ditory hallucinations may have an especially strong relation with diss
ociative processes, whereas subclinical delusions appeared to be most
strongly correlated with schizotypal thought processes. The results of
this study begin to clarify the phenomenon of hallucinatory and delus
ional experiences in a nonpsychotic population.
