    The idea for this research project came from a notion that there might be a lot of people with ADHD among the homeless population. Because of my own late ADHD diagnosis I wanted to do work as a ADHD advocate, I became an experience worker and came in contact with homeless people. My focus was triggered because in my lifspan I had been homeless on several occasions. I suspected that maybe as much as 30% of the homeless might e homeless because of ADHD.

    Fact checking

    When I tried to find out more about the connection ADHD and being homeless I found little literature and data. The few papers I found where among others an
    American and a Canadian paper with real data and to my surprise pointing to a prevalence of up to 50%. Most papers only talk about what we perceive as the major psychiatric disorders like psychosis and substance abuse. Without negating that problem I have long had my doubts if ADHD as probable underlying problem is even taken serious. That is when I decided to make work of this so people with ADHD can be helped better.

    With everything I discovered I decided to set up a research proposal that was sent to several parties. My first goal with this was to get feedback and support in form of endorsement. After this I continue as set out in the timeline. By now Impuls en woortblind the major Dutch ADHD support group and Het Straat Consulaat the support group for homeless and addicted people in The Hague have endorsed the the idea. If you or your organisation want to join please do contact me through the contact form.

    Resource collecting

    Interested parties and finances must be found before the plan can start. Although I have ideas about the design of the research, I cannot work it out on my own. I need professionals, preferably 1 or 2 academics, who want to help give the research a good basis and form. I also want to see which institutions can contribute with knowledge, support and subsidies. I want to close this phase around December 2019, after which preparations can begin.

    UPDATE: 14/06 In the fall of 2019, Akke Meilink psychiatrist at Equisto and pediatrician, author and chairman of Impuls en Woortblind Rob Rodrigues Pereira plan to conduct a number of exploratory talks with homeless people for the project.

    For the methodology, I refer again to the research proposal in which the goals are described. Given the target group, equality and respect are important. The researchers serve themselves to facilitate. In particular, also listen seriously to experiences, opinions and ideas. No research on homeless people, but research with homeless experts. The methodology should support this.

    I want to start looking for interviewers early. On the one hand to have enough, on the other hand to involve them in the design on time. I am thinking here of recruiting through faculties and colleges. Of course, publicity must also be given for this during contacts with institutions.

    Start fieldwork

    It should be possible to start the fieldwork by this time. Groups to be approached are, in addition to the people in shelters, also the so-called outdoor sleepers, and the couch surfers (people who stay with family and friends for short periods).

    I hope to be able to evaluate quickly because the statistical data can be processed already during collection time. Also formats can be prepared ahead for academic and popular presentation.

  • May 2021


    It is my intention to use both an academic paper and a popular brochure to publish the results. The methodology that I use to document on this website must also serve as a template for peer review and possible follow-up research. With this I hope not only to facilitate the academic community but also the growing group of serious evidence-based citizen scientists.
