Validity evidence, sensibility and specificity of the severity dimension of the SDSS alcohol dependence scale.

Objective: Therapeutic success in the treatment of alcohol use disorders highly depends on an appropriate diagnosis. The Substance Dependence Severity Scale –SDSS- is a scale that assesses substance dependence in dimensional terms and that follows the diagnostic criteria established by the international classification systems. The aim of this study is to provide validity evidence for the severity dimension of the alcohol dependence scale of the SDSS comparing it with the Mini International Neuropsychiatric Interview –MINI-, and others variables related to substance use included in the EuropASI.

Psychometric properties and adaptation of the ASRS in a Spanish sample of patients with substance use disorders: Application of two IRT Rasch models.

The Adult ADHD Self-Report Scale (ASRS; Kessler et al., 2005) is one of the most extensively used scales to detect attention-deficit hyperactivity disorder (ADHD) in adults. The aim of this work is to analyze the psychometric properties of the 18 ASRS items in people with substance use disorders (SUDs).

Reliability and validity of the Spanish version of the substance dependence severity scale.

Purpose: The purpose of this study was to estimate the reliability and provide evidence for the validity of the Spanish version of the Substance Dependence Severity Scale (SDSS).

Methods: A total of 211 substance abusers recruited at a public center that provides treatment for substance-related disorders in an outpatient setting were assessed. Reliability was estimated by Cronbach's α and test-retest.

[Spanish adaptation of the Substance Dependence Severity Scale: preliminar results].

The Substance Dependence Severity Scale -SDSS- is one of the few scales that assesses substance dependence and abuse according DSM criteria in dimensional terms. Several studies have provided evidence of psychometric validity and reliability in its English version, but there is no Spanish version available. The aim of this work was to describe the adaptation process of the English version of the SDSS into Spanish, and provide preliminary results on its reliability and validity evidence.
