Interpretation, emotional reactions and daily life implications of hallucination-like experiences in clinical and nonclinical populations.

Background: Research on Hallucination-Like Experiences (HLEs) has not yet explored whether people without psychosis who have HLEs attribute the same level of significance to them. This significance includes whether or not the HLEs elicit similar emotional reactions in people with and without psychosis, or if the HLEs occur in same context between the two groups. The objective of this study was to compare the characteristics of these experiences in a non-clinical group and a clinical group of patients with schizophrenia and schizophrenia spectrum disorders. Method: Both groups were evaluated to determine the prevalence of HLEs. After the evaluation, they were interviewed about the characteristics of these experiences. Results: Both groups sought to actively eliminate the HLEs, could identify the presence of a trigger factor, and experienced little perceived control. However, HLEs elicited more anxiety, discomfort and interference in daily life in the clinical group than in the nonclinical group. Furthermore, the clinical group members defined their hallucinations more negatively and were reported to have experienced them under stressful events. Conclusions: These findings suggest that the two experiences are not entirely equivalent, especially when taking into account the emotional reaction produced by these experiences and the meaning people attach to them.
