Hallucinations may occur in different sensory modalities e. Nonetheless, auditory hallucinations are the most common, especially in patients with schizophrenia David and Busatto, Hallucinatory or hallucinatory-like experiences cannot be reliably and validly assessed only as a matter of frequency or intensity. Portuguese version of the Launay-Slade Hallucinations Scale. This is not to deny the importance of studies on hallucinations in non-psychotic persons or the presence of hallucinations in normal population, but rather to challenge the kind of methodology used to date to assess this phenomenon.

Launay-Slade Hallucination Scale-Revised (LSHS-R) – Allie: Abbreviation / Long Form Info.

Indeed, the onset of psychosis is often preceded by an increased frequency of nonclinical psychotic symptoms e. Cognitive factors in predisposition to auditory and visual hallucinations. The first factor in the current analysis of the LSHS-R suggests that vivid and perhaps intrusive mental events may also be part of the predisposition to halluci- nations in healthy individuals.

Therefore, we hypothesized that the prevalence of hallucinatory experiences would be higher in individuals reporting more clinical symptoms. Dreaming of white bears: Further evidence of the multi-dimensionality of hallucinatory predisposition: Predisposition toward auditory hallucinations: This suggests that experiences reported in Factor II might be more easily differentiated from other forms of hallucinations.

AP conceived and designed the study and supervised data collection. A Keiser—Meyer—Olkin statistic of 0.

Quality of hallucinatory experiences: differences between a clinical and a non-clinical sample

In the last decades, a growing number of studies probed the pathophysiological mechanisms underlying the experience of hallucinations in nonclinical samples e. Three distinct states are thought to represent the phenotypic continuum of psychosis: Sometimes my thoughts seem as real as actual 0. An important argument for the validity of this solution is that repeated factor analyses with dif- ferent rotations yielded practically identical solutions.

Despite the increased number of studies probing the incidence of nonclinical hallucinations, the underlying phenomenological characteristics are still poorly understood. The reliability was quantified by measuring the internal consistency of the questionnaire with item-total score correlations correlation of each item with the total of the remaining itemsas well as with Cronbach’s alpha coefficients internal consistency and reliability.

The factor structure of the 12 variables was initially examined by PCA. Cambridge University Press— Auditory and visual hallucinations in university students. Table 1 displays the factor analysis of the Portuguese version of the LSHS, which resulted in a three-factor structure. The decision to use this LSHS version was motivated by the fact that it comprises items concerning several types of hallucinatory experiences auditory, visual, olfactory, and tactileand a response format that allows measuring additional relevant aspects of these experiences e.

Specifically, the more pleasant the hallucinatory experiences were perceived, the more controllable they were judged. This characterization can avoid diagnostic mistakes, e.

Quality of hallucinatory experiences: differences between a clinical and a non-clinical sample

Abstract In this study, we asked people from two samples a clinical one, consisting of patients with schizophrenia, and a non-clinical one, including university students to complete the Revised Hallucination Scale RHS as a self-questionnaire. These findings provided support for a continuum model of psychotic experiences that extends not only across diagnostic categories, but also into the non-clinical general population e. Psychotic-like experiences in nonpsychotic help-seekers: The same factor structure was obtained when the outliers were not trimmed.

Answers were automatically saved after the participants’ selection using the mouse. PC collected, analyzed and interpreted the data, and produced the drafting of the manuscript.

First, psychometric properties of the LSHS Portuguese adaptation were examined by assessing its sensitivity, internal validity and internal consistency, and reliability.
