ABSTRACT

BACKGROUND: The aim of this study was to adapt and obtain validity evidence of the Spanish Green Paranoid Thought Scales (S-GPTS). METHOD: 191 Spanish people responded to S-GPTS, Peters Delusions Inventory (PDI), and measures of psychopathology. RESULTS: Principal Component Analyses on the polychoric correlation matrix identified two factors accounting for 71.0% of the cumulative variance. Cronbach alphas for S-GPTS total and its subscales were above .90 in clinical and non-clinical group. The value of the area under the receiver operating characteristic curve was higher for the S-GPTS (.898), than for the PDI (.859). The best S-GPTS threshold to discriminate between cases and non-cases was 92 (sensitivity, 97.35%; specificity, 65%). S-GPTS scores positively correlated with PDI and measures of anxiety and depression. CONCLUSION: The S-GPTS has adequate psychometric properties to provide valid measures of delusional ideation in a Spanish population


ANTECEDENTES: el objetivo del presente estudio fue adaptar y obtener evidencias de validez de la versión española de las escalas de pensamiento paranoide de Green (S-GPTS). MÉTODO: 191 participantes españoles respondieron al S-GPTS, al Inventario de Delirios de Peters (PDI) y a medidas de psicopatología.RESULTADOS: el Análisis de Componentes Principales a partir de la matriz de correlaciones policóricas identificó dos factores que explicaban el 71% de la varianza acumulada. El coeficiente α de Cronbach para el S-GPTS y sus subescalas fue superior a .90 en ambos grupos. El valor del área bajo la curva ROC fue más alto para el S-GPTS (.898) que para el PDI (.859). El punto de corte que mejor discriminaba entre el grupo clínico y el no clínico fue 92 (97,35% de sensibilidad, 65% de especificidad). Las puntuaciones del S-GPTS correlacionaron positivamente con el PDI y con medidas de ansiedad y depresión. CONCLUSIONES: el S-GPTS posee propiedades psicométricas adecuadas para proporcionar una medida válida de la ideación delirante en población española

ABSTRACT

Synthetic analogs of the cathinone molecule have seen increasing recreational use as substitutes for cocaine, 3,4-methylenedioxymethamphetamine (ecstasy) and methamphetamine. Repeated use of these drugs is associated with a paranoid hallucinatory delirium. A subset of patients using these substances develops a syndrome of extreme agitation and violent behavior that has been reported following the use of other stimulant drugs that also produce rapid changes in brain monoamines. This syndrome, characterized as "excited delirium," presents to the acute care setting with a challenging combination of paranoia, severe agitation and violent behavior. These patients frequently suffer from dehydration, skeletal muscle damage and renal failure that may lead to multiorgan failure and death. Management of these individuals requires careful consideration of the consequences of interventions commonly implemented in medical settings to control dangerous aggressive behavior.

ABSTRACT

The authors present the case of a 60-year-old woman with elaborate paranoid delusions and cognitive impairment found during a workup for atypical chest pain. Clinical evaluation revealed mild dementia, and radiography showed basal ganglia calcification consistent with Fahr's disease. She was treated with risperidone and transferred to a psychiatric inpatient unit for definitive care. Psychiatrists should consider Fahr's disease as a differential diagnosis in the evaluation of psychosis and cognitive impairment when neuroimaging reveals calcification of the basal ganglia.

ABSTRACT

Introducción: La alteración del comportamiento, una afectividad negativa y el abuso sexual y/o físico en la infancia están relacionados con el abuso de sustancias y la conducta sexual de riesgo. Material y métodos: Analizamos la conducta sexual de un grupo de drogodependientes (n = 61) y correlacionamos con las características de personalidad. Se aplicaron análisis de variancia (ANOVA), test de la *2 y regresión lineal como procedimientos estadísticos. Resultados: Los rasgos de personalidad paranoide, esquizotípico y antisocial se correlacionaron con un inicio precoz de la conducta sexual. Hemos encontrado diferencias significativas entre la edad de inicio de la primera experiencia sexual y el subtipo de drogodependencia (F = 3,801; p < 0,05). Conclusión: Hay una relación entre el uso de sustancias tóxicas, la conducta sexual de riesgo y las características de la personalidad del individuo. Los resultados apuntan a que, entre la población drogodependiente, los rasgos de personalidad pueden ser un factor de riesgo y desencadenar el desarrollo del abuso de sustancias y la conducta sexual de riesgo (AU)
