Participaron sujetos, con una edad de El coeficiente alpha de Cronbach de la DES fue de 0. Dissociative disorders are characterized by impaired conscious integration functions, personal identity, memory and environment perception. Their frequent psychopathological manifestations are amnesia, depersonalization, fugue states, extra sensorial experiences, trance states and total personality changes. They usually appear under different life stressors, and their clinical course is highly variable.
This wide variation is one of the indicators of the complexity of this diagnostic entities and of its difficulty to be studied. Culture is a key factor in functionality of subjects with a dissociative disorder, because the acceptance of many of its clinical features varies.
It is accepted that these diagnostic categories are barely-recognized, not only by general physicians, but by experienced mental health specialists. Unfortunately, structured interviews face an important limitation as there is a lack of trained, and some times, experienced psychopathologist, a fact that difficults to use them in large samples.
Self-report instruments, when they show good reliability and validity, are of great value in terms of time, costs and feasibility. Their major limitation is the low reliability that they show in psychiatric conditions in which lack of insight is present psychotic disorders. To evaluate the psychometric properties of translated versions of instruments is highly desirable.
This is specially important when elusive disorders are being evaluated. Given that the cultural environment of Mexico is surrounded by several factors that influence this kind of disorders, the availability of reproducible research instruments is of outmost relevance. Therefore, the Dissociative Experiences Scale DES -the most widely used measure in this field- in contrast with the Dissociative Disorders Interview Schedule DDIS , was evaluated, with the purpose to give a first approach to a 12 month prevalence of some Dissociative disorders in Mexican psychiatric patients.
A non-random, consecutive sample of male and female patients, between 18 and 63 years old were included. They were receiving treatment, regardless of the diagnosis, at the Institute of Mental Health of Jalisco, from the State's Ministry of the Health in Mexico.
The ethics committee authorized the study, and they all gave informed consent. The DDIS was translated by one bilingual psychiatrist, and independently reviewed by another. Consensus was reached in controverted items.
Once a final translated version was obtained, it was given to 10 subjects mainly with primary school level , to assess item understanding. A second review was performed to reach a culturally compatible version, concentrating in respecting item content validity. Back translation was not considered, because this method does not capture common language of low school population, which is the case of most Mexicans. This is a 28 items, self-report scale, designed to evaluate different kinds and severity of Dissociative conditions, in a 0 to range.
Most populations without a psychiatric condition or with a non-Dissociative disorder, scored under A cut-off point of 30, usually indicates the possibility of a Dissociative disorder diagnosis. Given that a Spanish version of the DES is available from Spain, only an idiomatic adaptation to Mexican Spanish was performed changes in slang or word content differences between countries.
It is to be applied by mental health professionals, properly trained on its use. It does not give a total score, it assesses each disorder independently. As previous studies performed in different languages, it has adequate psychometric properties, and is the usual golden standard for Dissociative categories.
Demographic and clinical variables were obtained, as well as the diagnosis assigned in the patient chart. To analyze results two procedures were planned: 1 compare DES total score punctuation between positive and negative presence of Dissociative disorders according with the DDIS and 2 compare between patients with a Dissociative disorder with or without concomitant major depression.
The DES internal consistency index was 0. Mean DES total score was The most common concomitant diagnosis as assessed in the patient chart was unipolar major depression 17 When a Dissociative disorder was comorbid with major depression, comparing it with Dissociative disorders only, the difference was greater Dissociative disorder measurements evaluated, seem to work adequately in Mexican population.
Prevalence of dissociative disorders found in this psychiatric population, is consistent with other studies. Further research in the field is needed, to evaluate the influence of cultural factors, including rural and indigenous samples.
