LAUNAY SLADE HALLUCINATION SCALE PDF

Akijas 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. Indeed, the onset of psychosis is often preceded by an increased frequency of nonclinical psychotic symptoms e.

What is different is the personal quality of these experiences. Hallucinatory or hallucinatory-like experiences cannot be reliably and validly assessed only as a matter of frequency or intensity. Their assessment requires a precise characterization of the phenomenal quality of the experience. As recently argued by Kendler 19 , psychopathological assessment should neither be confined to determining the presence or absence of a given symptom, nor should it simply focus on surface symptoms picked for their reliability.

Rather, it should look for deeper phenomena which may emerge only from careful phenomenological analysis. The results of this study suggest that it is not advisable to analyze and study hallucinations, especially in non-clinical populations, using research protocols based solely on yes-or-no answers to questionnaires.

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. The issue addressed by this paper is the importance of the quality of such experiences, and what makes them similar or radically different from those in persons with schizophrenia. We need an in-depth, fine-tuned characterization of the phenomenal quality of abnormal perceptual experiences, including hallucinations.

This characterization can avoid diagnostic mistakes, e. Without such an effort to phenomenologically characterize normal as well as abnormal experiences, any attempt at a comparison is at risk of leading to non-informative conclusions A limitation of this study is that the non-clinical sample was made up only of students and cannot be considered representative of the general population.

In addition, the details provided by the participants must be understood within the specific Spanish cultural context. In future research, it would be of interest to compare these results with those obtained in samples from other cultures, as well as in different clinical e. References 1. David AS.
