Attention deficit/hyperactivity disorder (ADHD) is an increasingly recognized
comorbid condition in subjects with substance use disorders (SUDs). This paper
describes the methods and study population of the International ADHD in Substance
Use Disorders Prevalence (IASP) study. Objectives of the IASP are to determine
the prevalence of ADHD in adult treatment seeking patients with SUD in different
countries and SUD populations, determine the reliability and validity of the
Adult ADHD Self-report Scale V 1.1 (ASRS) as ADHD screening instrument in SUD
populations, investigate the comorbidity profile of SUD patients with and without
ADHD, compare risk factors and protective factors in SUD patients with and
without a comorbid diagnosis of ADHD, and increase our knowledge about the
relationship between ADHD and the onset and course of SUD. In this
cross-sectional, multi-centre two stage study, subjects were screened for ADHD
with the ASRS, diagnosed with the Conner’s Adult ADHD Diagnostic Interview for
DSM-IV (CAADID), and evaluated for SUD, major depression, bipolar disorder, anti
social personality disorder and borderline personality disorder. Three thousand
five hundred and fifty-eight subjects from 10 countries were included. Of these
40.9% screened positive for ADHD. This is the largest international study on this
population evaluating ADHD and comorbid disorders.
