Design outcomes

Primary

Measure	Time frame
The primary objective of this study is to estimate the prevalence of ADHD in non-psychotic adults in psychiatric outpatient care as assessed by the Diagnostic Interview for ADHD in Adults (DIVA) instrument according to DSM-IV criteria.	—

Secondary

Measure	Time frame
The secondary objectives of the study are as follows: - to characterize the Adult ADHD population as diagnosed by DIVA in terms of symptoms, functioning, quality of life, work status and resource use prior to study entry and also the population of patients without ADHD diagnosis in psychiatric outpatient care - to estimate the prevalence of ADHD in adults in non-psychotic psychiatric outpatient care in different settings and countries or groups of countries with similar mental health organization/health care systems - to estimate the prevalence of ADHD in non-psychotic adults in psychiatric outpatient care based on meeting for example only either 5 or 4 DSM-IV criteria from the attention or hyperactivity/impulsivity symptoms list and with and without the 7- year age limit for childhood onset of symptoms as per DSM-IV, foreseeing the upcoming changes in the next generation of diagnostic criteria - to explore properties of Adult ADHD Self-Report Scale Symptom Checklist ;(ASRS) and/or the ADHD questions of the Provisional Diagnostic Instrument-4 (PDI-4) as derived from ASRS by examining the DIVA item results of patients with various scores on the screening instruments - to estimate the prevalence of other non-psychotic mental disorders in psychiatric care (depression/dysthymia, bipolar disorder, obsessive-compulsive disorder, anxiety disorders, eating disorders, substance/alcohol abuse or dependence, antisocial or borderline personality disorders, autism spectrum disorder) and to estimate their comorbidity with adult ADHD - to provide additional data to support validation of the DIVA.	—
