Evaluation of Dream Content among Patients with Schizophrenia, their Siblings, Patients with Psychiatric Diagnoses other than Schizophrenia, and Healthy Control.

OBJECTIVE

Schizophrenia is a chronic psychotic disorder with unknown etiology that causes cognitive impairment, affecting thinking, behavior, social function, sleep and dream content. This study considered the dream content of patients with schizophrenia, siblings of patients with schizophrenia, patients with psychiatric diagnoses other than schizophrenia, and a group of healthy controls. The aim of this study was to compare the dream content of patients with schizophrenia with dream content of individuals with other mental disorders, first degree relatives of patients with schizophrenia, and community controls.

METHOD: Seventy-two patients were selected and placed in 4 groups. The first group consisted of 18 inpatients with schizophrenia whose medications were stable for at least four weeks; the second group consisted of 16 nonpsychotic mentally ill inpatients; the third group consisted of 18 individuals who were siblings of patients with schizophrenia; and the fourth group consisted of 20 healthy individuals in the community with no family history of mental or somatic disorders. The four groups were matched by age and gender. A 14-item dream content questionnaire was administered for all the participants, and the Positive and Negative Symptoms Scale (PANSS) was also administered for the two groups of hospitalized patients.

RESULTS

Results showed that there were significant differences in dream content among groups included friends acquaintances, females and colorful components. No significant differences were found between the positive and negative subscales of PANSS and any of the dream questionnaire subscales.

CONCLUSION

Our results suggest that there were a few changes in the dream content of the patients with schizophrenia compare to other groups.
