DSM-IV and DSM-5 alcohol use disorder among young Swiss men.

BACKGROUND AND AIMS: Previous studies suggest that the new DSM-5 criteria for alcohol use disorder (AUD) will increase the apparent prevalence of AUD. This study estimates the 12-month prevalence of AUD using both DSM-IV and DSM-5 criteria and compares the characteristics of men in a high risk sample who meet both, only one and neither sets of diagnostic criteria. DESIGN, SETTING AND PARTICIPANTS: 5943 Swiss men aged 18-25 years who participated in the Cohort Study on Substance Use Risk Factors (C-SURF), a population-based cohort study recruited from three of the six military recruitment centres in Switzerland (response rate = 79.2%). MEASUREMENTS: DSM-IV and DSM-5 criteria, alcohol use patterns, and other substance use were assessed. FINDINGS: Approximately 31.7% (30.5-32.8) of individuals met DSM-5 AUD criteria [21.2% mild (20.1-22.2); 10.5% moderate/severe (9.7-11.3)], which was less than the total rate when DSM-IV criteria for alcohol abuse (AA) and alcohol dependence (AD) were combined [36.8% overall (35.5-37.9); 26.6% AA (25.4-27.7); 10.2% AD (9.4-10.9)]. Of 2479 respondents meeting criteria for either diagnoses, 1585 (63.9%) met criteria for both. For those meeting DSM-IV criteria only (n = 598, 24.1%), hazardous use was most prevalent, whereas the criteria larger/longer use than intended and tolerance to alcohol were most prevalent for respondents meeting DSM-5 criteria only (n = 296, 11.9%). Two in five DSM-IV alcohol abuse cases and one-third of DSM-5 mild AUD individuals fulfilled the diagnostic criteria due to the hazardous use criterion. The addition of the craving and excluding of legal criterion, respectively, did not affect estimated AUD prevalence. CONCLUSIONS: In a high-risk sample of young Swiss males, prevalence of alcohol use disorder as diagnosed by DSM-5 was slightly lower than prevalence of DSM-IV diagnosis of dependence plus abuse; 63.9% of those who met either criterion met criteria for both.

Prevalence and correlates of DSM-5 bipolar and related disorders and hyperthymic personality in the community.

BACKGROUND: To 1) establish the lifetime and 12-month prevalence of DSM-5 bipolar and related disorders including the new algorithmically defined conditions grouped within Other Specified Bipolar and Related Disorders (OSBARD) as well as hyperthymic personality in a randomly selected community sample, and 2) determine the clinical relevance of the OSBARD category in terms of sociodemographic characteristics, course, comorbidity and treatment patterns by comparing the subjects of this category to those with bipolar-I (BP-I), bipolar-II (BP-II), major depressive disorder (MDD), and those with no history of mood disorders. METHODS: The semi-structured Diagnostic Interview for Genetic Studies was administered by masterslevel psychologists to a random sample of an urban area (n=3'719). RESULTS: The lifetime prevalence was 1.0% for BP-I, 0.8% for BP-II, 1.0% for OSBARD and 3% for hyperthymic personality. Subjects with OSBARD were more severely affected than subjects without a history of mood disorders regarding almost all clinical correlates. Compared to those with MDD, they also revealed an elevated risk of suicidal attempts, lower global functioning, more treatment seeking and more lifetime comorbidity including anxiety, substance use and impulse-control disorders. However, they did not differ from subjects with BP-II. LIMITATIONS: Small sample sizes for bipolar and related disorders and potential inaccurate recall of symptoms. CONCLUSIONS: The modifications of diagnostic criteria for manic/hypomanic episodes according to the DSM-5 only marginally affect the prevalence estimates for BP-I and BP-II. The new DSM-5 OSBARD category is associated with significant clinical burden, is hardly distinct from BP-II with respect to clinical correlates and deserves similar clinical attention.

Exploring the proposed DSM-5 diagnostic threshold and severity scale for the alcohol use disorder

Aims :¦Several studies have questioned the validity of separating the diagnosis of alcohol abuse from that of alcohol dependence, and the DSM-5 task force has proposed combining the criteria from these two diagnoses to assess a single category of alcohol use disorders (AUD). Furthermore, the DSM-5 task force has proposed including a new 2-symptom threshold and a severity scale based on symptom counts for the AUD diagnosis. The current study aimed to examine these modifications in a large population-based sample.¦Method :¦Data stemmed from an adult sample (N=2588 ; mean age 51.3 years (s.d.: 0.2), 44.9% female) of current and lifetime drinkers from the PsyCoLaus study, conducted in the Lausanne area in Switzerland. AUDs and validating variables were assessed using a semi-structured diagnostic interview for the assessment of alcohol¦and other major psychiatric disorders. First, the adequacy of the proposed 2- symptom threshold was tested by comparing threshold models at each possible cutoff and a linear model, in relation to different validating variables. The model with the smallest Akaike Criterion Information (AIC) value was established as the best¦model for each validating variable. Second, models with varying subsets of individual AUD symptoms were created to assess the associations between each symptom and the validating variables. The subset of symptoms with the smallest AIC value was established as the best subset for each validator.¦Results :¦1) For the majority of validating variables, the linear model was found to be the best fitting model. 2) Among the various subsets of symptoms, the symptoms most frequently associated with the validating variables were : a) drinking despite having knowledge of a physical or psychological problem, b) having had a persistent desire or unsuccessful efforts to cut down or control drinking and c) craving. The¦least frequent symptoms were : d) drinking in larger amounts or over a longer period than was intended, e) spending a great deal of time in obtaining, using or recovering from alcohol use and f) failing to fulfill major role obligations.¦Conclusions :¦The proposed DSM-5 2-symptom threshold did not receive support in our data. Instead, a linear AUD diagnosis was supported with individuals receiving an increasingly severe AUD diagnosis. Moreover, certain symptoms were more frequently associated with the validating variables, which suggests that these¦symptoms should be considered as more severe.

Taxometric analysis of DSM-IV and DSM-5 alcohol use disorders.

BACKGROUND: With preparations currently being made for the Diagnostic and Statistical Manual of Mental Disorders-5th Edition (DSM-5), one prominent issue to resolve is whether alcohol use disorders are better represented as discrete categorical entities or as a dimensional construct. The purpose of this study was to investigate the latent structure of DSM-4th edition (DSM-IV) and proposed DSM-5 alcohol use disorders. METHODS: The study used the Wave 2 National Epidemiologic Survey on Alcohol and Related Conditions (NESARC) to conduct taxometric analyses of DSM-IV and DSM-5 alcohol use disorders defined by different thresholds to determine the taxonic or dimensional structure underlying the disorders. RESULTS: DSM-IV and DSM-5 alcohol abuse and dependence criteria with 3+ thresholds demonstrated a dimensional structure. Corresponding thresholds with 4+ criteria were clearly taxonic, as were thresholds defined by cut-offs of 5+ and 6+ criteria. CONCLUSIONS: DSM-IV and DSM-5 alcohol use disorders demonstrated a hybrid taxonic-dimensional structure. That is, DSM-IV and DSM-5 alcohol use disorders may be taxonically distinct compared to no disorder if defined by a threshold of 4 or more criteria. However, there may be dimensional variation remaining among non-problematic to subclinical cases. A careful and systematic program of structural research using taxometric and psychometric procedures is warranted.

Des "psychoses affectives" aux "caractéristiques psychotiques" : les symptômes psychotiques selon le DSM, discutés à la lumière d'une série de 16 cas de dépression psychotique = From "affective psychoses" to "psychotic features": DSM's psychoticsymptoms discussed in the light of a series of 16 cases of psychoticdepression.

Objectifs. - Le DSM-5 donne une définition du symptôme psychotique indépendante de tout concept depsychose. Chez les patients dépressifs, la présence d'hallucination ou d'idée délirante, quelle que soit leurforme clinique, conduit en principe à diagnostiquer une dépression psychotique et à prescrire des neurolep-tiques. Les symptômes psychotiques sont subdivisés par le DSM en « congruents » ou « non congruents » àl'humeur. Nous discutons de la pertinence d'une catégorie de symptômes psychotiques « atypiques », peuévocateurs d'une psychose au sens classique du terme. Méthode. - Discussion de la définition opérationnelle des symptômes psychotiques du DSM, étude d'unesérie de 16 patients chez qui un diagnostic de dépression psychotique a été posé. Résultats. - Sur les 16 patients, deux seulement présentaient des symptômes psychotiques classiques, évo-cateurs d'une psychose. Chez les autres, le diagnostic reposait sur la présence de symptômes très atypiques,comme des hallucinations visuelles par exemple.

Resultados preliminares de una escala experimental para la evaluación del trastorno antisocial de la personalidad según los criterios diagnósticos DSM-III

El estudio que se presenta consiste en la aplicación de una escala ajustada a criterios para el diagnóstico del Trantorno Antisocial de la Personalidad (eje II, 301.70) a una población penitenciaria a efecto de comprovar su valor discriminativo resto al diagnóstico clínico. La escala propuesta se reveló altamente sensible (87,5%), específica (90%) y predictiva (valor predictivo positivo del 89% y valor predectivo negativo del 87%) frente a la evaluación clínica. La evaluación se llevó a cabo por dos clínicos especializados mediante la utilización de una entrevista semiestructurada extraida y adaptada del DIS (Robins, 1981), obteniéndose un índice concordancia intragrupo entre evaluadores de 8.82. Se hacen refencias a la posible explicación de los falsos positivos obtenidos en la escala TAP.

Escalas empíricas derivadas de la escala de Desviación Psicopática del MMPI, para la evaluación del trastorno antisocial de la personalidad del DSM-III en delincuentes y no delincuentes

Se realiza un análisis de los ítems de la escala de Desviación Psicopática (Pd;50 ítems) del MMPI que más discriminan entre delincuentes diagnosticados del trastorno antisocial de la personalidad (DSM-III), de delincuentes que no tienen el trastorno y estudiantes, del que se resulta dos escalas (Pd-P;24 ítems y Pd-N;33 ítems). Estas escalas obtienen mayor sensibilidad y especificidad que la propia escala Pd respecto al trastorno. Psicométricamente tienen mayor validez y fiabilidad, propiedades, que junto a su brevedad, hacen aconsejable su uso en el estudio de la personalidad antisocial.

The Psychometric Properties of the French Version of the Personality Inventory for DSM-5.

In the context of the publication of DSM-5, the Personality Inventory for DSM-5 (PID-5) has been proposed as a new dimensional assessment tool for personality disorders. This instrument includes a pool of 220 items organized around 25 facets included in a five-factor second-order domain structure. The examination of the replicability of the trait structure across methods and populations is of primary importance. In view of this need, the main objective of the current study was to validate the French version of the PID-5 among French-speaking adults from a European community sample (N=2,532). In particular, the assumption of unidimensionality of the 25 facet and the five domain scales was tested, as well as the extent to which the five-factor structure of the PID-5 and the DSM-5 personality trait hierarchical structure are replicated in the current sample. The results support the assumption of unidimensionality of both the facets and the domains. Exploratory factor and hierarchical analyses replicated the five-factor structure as initially proposed in the PID-5.

Asignaturas pendientes del DSM-5

El presente artículo analiza las críticas generadas a partir de la publicación del Manual diagnóstico y estadístico de los trastornos mentales, quinta edición (DSM-5), ya anunciadas parcialmente durante las últimas fases de su elaboración. Una parte de las críticas se ha centrado en los cambios de los criterios diagnósticos para determinados trastornos y en la incorporación al DSM de nuevas entidades. Sin embargo, otra vertiente crítica va dirigida a la falta de validez de los diagnósticos del DSM, por cuyo motivo se ha cuestionado su eficiencia en el campo de la investigación. El fallo básico del DSM se centra en la incoherencia de un modelo basado en un amplio repertorio de definiciones de entidades categóricas, todas ellas con un alto componente de comorbilidad. Como propuesta para superar el bloqueo generado en la investiga ción y la parquedad de avances terapéuticos, el Instituto Nacional de Salud Mental de estados Unidos ha propuesto una estrategia de investigación cuyo punto de partida se sustenta en la identificación y el estudio de las dimensiones básicas de las disfunciones que se presentan de modo transversal en los trastornos mentales.

Diagnosing Gender: Transitivity Analysis on the Diagnostic Category of Gender Dysphoria in DSM-5

Tässä tutkielmassa analysoidaan teoksessa ’Diagnostic and Statistical Manual of Men-tal Disorders, Fifth Edition’ (DSM-5) ja tarkemmin sen kappaleessa ’Gender Dysphoria’ käytettyä kieltä. DSM-5 on mielenterveydenalan ammattilaisille suunnattu luokittelu virallisesti tunnustetuista mielenterveyden häiriöistä ja se sisältää myös oireiden kuvai-luun perustuvat ohjeet näiden mielenterveyshäiriöiden diagnosoimiseksi. ’Gender dys-phoria’ (vapaasti suomennettuna sukupuolidysforia) on lääketieteellinen termi, joka viittaa biologisesta sukupuolesta eriävän sukupuoli-identiteetin aiheuttamaan henki-seen pahoinvointiin. Sukupuoli-identiteetin ja mielenterveysongelman yhdistäminen sisältää ideologisiin arvoihin pohjautuvia perusteluja ja tässä tutkielmassa analysoi-daan ’Gender Dysphoria’ – kappaleen ideologista sisältöä kriittisestä näkökulmasta. Tutkimuksen tarkastellaan ’Gender Dysphoria’ – kappaleessa käytetyn kielen ideologi-sia heijastumia ja niiden sosiaalisia vaikutuksia kolmen tutkimuskysymyksen avulla: 1) Kuinka diagnosoitu henkilö esitetään tekstissä? 2) Kuinka tekstissä rakennetaan kuvaa sukupuolidysforiasta mielenterveyshäiriönä? 3) Miten analyysin tulokset saattavat vai-kuttaa käsitykseen sukupuolen yhteydestä mielenterveyteen ja sukupuolidysforian diagnosoimiseen. Analyysissä käytetään metodina M. A. K. Hallidayn transitiivisuusteo-riaa ja tulosten sosiaalisia vaikutuksia analysoidaan Norman Faircloughn diskurssiana-lyysimallin avulla. Transitiivisuusanalyysin avulla tarkastellaan kirjoittajien tekemiä va-lintoja kielenkäytön suhteen, jotka Hallidayn teorian mukaan heijastavat kirjoittajien henkilökohtaisia kokemuksia ympäröivästä maailmasta. Tutkimus paljasti, että sukupuolidysforia esitetään mielenterveysongelmana erotta-malla se yksilöstä erilliseksi toimijaksi, joka suorittaa erilaisia prosesseja yksilön sisällä. Yksilöistä erityisesti lapset esitetään tekstissä voimakkaasti perinteisiin sukupuoliroo-leihin pohjautuvan ideologian valossa, joka heijastuu oireiden kuvailuun. Analyysi osoittaa myös logiikkaongelmia lasten oireiden kuvailussa, jotka johtavat ristiriitoihin oireiden ja mielenterveysongelman yhteydessä ja kumoavat perusteet, joiden pohjalta lapset diagnosoidaan. Tutkimuksen lopussa ehdotetaan, että sukupuolidysforiaan liit-tyvien diagnoosiohjeiden ja – kriteerien perusteita muokataan yleisesti sukupuoli-identiteetin itsemääräämisoikeuteen pohjautuvaksi ja lasten osalta tekstiin sisällytet-täisiin mahdollisia tieteellisiä perusteluja, jotka kumoaisivat diagnoosiohjeiden nyky-muodossaan sisältämät ristiriidat ja perustelisivat lasten diagnosoinnin oikeellisuuden
