The Attention Deficit Hyperactivity Disorder (ADHD) Observational Research in Europe (ADORE) project aims to describe the relationship between prescribed treatment regimen and quality of life in ADHD patients across Europe over a 2-year period. As an adjunct to the ADORE study, a survey was conducted to assess the availability and range of ADHD treatment services in the UK. A questionnaire was developed to assess service provision at 20 UK ADORE sites. These data give information regarding the assessment process (i.e. the formal psychological instrumentation used), whether information is requested from schools, and what other medical and allied health care specialities are frequently involved in the diagnosis. Results of the survey provide an important insight into the ADHD-related services provided by ADORE centres, as well as highlighting the availability and limitations of such services.
