Exploring the predictive properties of the Hayes Ability Screening Index subtest background information in identifying individuals with MBID among in-patients with SUD.

Introduction: For individuals with substance use disorder (SUD), mild to borderline intellectual disability (MBID) goes undetected in treatment clinics. The Hayes Ability Screening Index (HASI) has been found to be a valid, time-saving screening instrument for MBID in SUD treatment. MBID can have significant implications for treatment planning and outcomes.

Prevalence and Characteristics of Borderline Intellectual Functioning in a Cohort of Patients With Polysubstance Use Disorder.

To determine the prevalence and associated demographic and clinical features of borderline intellectual functioning (BIF) among individuals with polysubstance use disorder (pSUD). We applied a cross-sectional analytical design to data from the Norwegian STAYER study ( = 162), a cohort study of patients with a pSUD from the Stavanger University hospital catchment area. We used Wechsler Abbreviated Scale of Intelligence Full Scale IQ (FSIQ) to define BIF (FSIQ = 70-85) and non-BIF (FSIQ = >85) and collected demographic and clinical data using semi-structured interviews and self-reports on the Symptom Checklist 90-Revised (SCL-90-R) and the Satisfaction With Life Scale (SWLS).

Prevalence of drug use among adults with intellectual disabilities compared with drug use in the general population.

Purpose: Individuals with intellectual disabilities (IDs) have more health problems, a poorer general health, and a shorter life expectancy than individuals in general. High rates of drug use in IDs have been reported. Despite the increasing interest in health problems in individuals with IDs, little is known about their drug use.

Screening for intellectual disabilities: a validation of the Hayes Ability Screening Index for in-patients with substance use disorder.

Background: There is a reason to believe that many individuals with substance use disorder (SUD) in contact with services have an undiagnosed intellectual disability (ID). Assessing ID in persons with SUD can be challenging due to the influence of substances, time consumption, and specific requirements for the education of the assessor. On the other hand, an undiagnosed condition may lead to a lack of treatment adjustment and may result in drop-out from treatment or lack of treatment effect.

Intellectual Functioning in In-Patients with Substance Use Disorders: Preliminary Results from a Clinical Mediation Study of Factors Contributing to IQ Variance.

Aims: To investigate the direct effect of different childhood difficulties on adult intelligence coefficient (IQ) and their possible indirect effect through the mediating pathways of education and severity substance use.

Participants: Ninety in-patients aged 19-64. The participants had abstained from substance use for at least 6 weeks and had different substance use profiles.
