Aim of Investigations
Approximately 4 % of adults have ADHD. This condition remains underdiagnosed as only 10. 9% of adults with ADHD receive treatment. Small studies suggest that there is an association with analgesics consumption, CNCP and ADHD. This possible association is what motivated us to create a research protocol and screen ADHD in adults with CNCP. 
Methods
After ethics approval by the Human Research Ethics Committee at CRCHUM, (Protocol 18.288), we started the research protocol. We present the preliminary results of a part of our protocol. six electronic questionnaires were used. We present here the analysis of 2 questionnaires:  Demographic questionnaire; Self-Report Scale (ASRS-v1.1) for ADHD. Results were compiled using the Survey Monkey software.  

Results
A total of 65 patients were invited 10 don’t participate and 55 accept to participate (29 female and 26 male) age between 18-65 years old. The different types of pain were chronic spine pain, chronic post-surgical pain, CRPS, neuropathic pain and fibromyalgia. The average score of pain was 6,59. 22 of 55 (40%) was positive to the ASRS-v1.1. 7 of 55 patients were diagnoses and treated for ADHD.

Conclusions
Our preliminary results demonstrate a close relationship between CNCP and a positive screening of ADHD, but the high number of positive ADHD makes us to believe that the ASRS-v1.1 as screening tool might not be best screening for a CNCP population. Additional use of family history of ADHD and the evaluation of history of ADHD during adolescence are necessaries to improve the screening.
