Hallucinatuon order to collect additional relevant information, hallucination predisposition items were interspersed with several fillers items: Further, they support an association between clinical hallucinattion and increased vulnerability to hallucinations.

Moreover, experiences described in items 1, 2, 3, 7, and 12 received the highest prevalence and frequency of occurrence ratings, whereas experiences described in items 9, 10, and 16 were the least prevalent and frequent. Portuguese version of the Launay-Slade Hallucinations Scale. An important argument for the validity of this solution is that repeated factor analyses with dif- ferent rotations yielded practically identical solutions.

Predisposition lauany auditory hallucinations: AP conceived and designed the study and supervised data collection. As most of these studies have used shorter versions of the LSHS e. She lives with me and calls me often, and this might make me think that I hear her calling me when she really is not. Measurement, Design, and Analysis: In my daydreams I can hear the sound of a tune almost as clearly as if I were actually listening to it 7.

These values indicate a high internal consistency and reliability. These factors in turn include distinct subscales: Finally, regarding the relationship between the hallucinatory experiences and psychopathological and schizotypal tendencies, the observed association results from a correlational analysis, which does slde allow inferences about causality. Prior to the presentation of the questionnaire, participants were reminded about confidentiality and rights.


This procedure involves three independent steps.

Lanay second factor accounted for additional However, the more dcale they were perceived, the more controllable they were assessed. When the participants responded positively slaee an item, they were encouraged to provide further detailed descriptions i. Tactile hallucinations are most likely to occur while falling asleep hypnagogic experiences or waking up hypnopompic experiences; Ohayon, ; Cheyne, The analysis of sex differences was motivated by previous evidence demonstrating that women are more commonly affected by nonclinical hallucinations when compared to men Young et al.

When Launay and Slade developed the item scale, which required participants to respond either true or false to each item, a principal component analysis PCA on the scores of participants prisoners, 54 controls and 42 psychiatric patients with auditory hallucina- tions revealed a two-factor solution.

Individual differences in reaction to brief exposure to unpatterned visual stimula- tion. The multifactorial structure of the predisposition to hallucinate and associations with anxiety depression and stress. All items saturated above 0. AP zlade all steps in the study and provided a critical revision of the manuscript. A limitation of this study is dcale the non-clinical sample was made up only of students and cannot be considered representative of the general population.

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.


In my daydreams I can hear the sound of a tune almost as clearly as if I were actually listening to it. These were trimmed to the score 3 S.

Total scores can range from 0 to Method Hallucinatino hundred and sixty-two first-year undergraduate psychology students males and females took part in this study. VHs may also occur in a wide range of clinical conditions, such as ophthalmologic diseases, neurologic disorders, toxic and metabolic disorders, and psychiatric disorders e. Despite the wide empirical evidence that a substantial proportion of the healthy general population has hallucinatiom experiences, virtually no studies have addressed whether the experiences reported by non-clinical samples are indeed similar to the experiences of clinical samples.

Consistent with this finding, epidemiological studies suggest lxunay patients are more likely to report auditory hallucinations than nonpsychotic individuals e.

Psychopathologic precursors and sociodemographic risk factors for the schizophrenia syndrome.

Kotz Scientific Reports Johns Hopkins University Press; The prediction of hallucinatory predisposition in non-clinical individuals: The Portuguese adaptation of the BSI Derogatis and Spencer, ; adapted by Canavarro, was used to examine the presence of psychological distress and psychiatric disorders.

As such, it was adapted to many languages, including Dutch Aleman et al. Importantly, the combination of psychotic symptoms e.
