Study summary

Attention deficit hyperactivity disorder (ADHD) is a common condition that affects children's behaviour, attention and activity levels. Medicines can be an effective treatment for ADHD, but it is often difficult to know which medicine will work best for a particular child. As a result, some children may need to try several medicines before finding one that is effective and well tolerated. This study aims to test a new online decision-support system called PETRA. The system is designed to help children, parents or carers, and doctors make shared decisions about ADHD medication. The study will assess whether it is practical and acceptable to run a larger clinical trial comparing this personalised approach with standard care.

  • Access to internet and email

Exclusion Criteria:

  • Based on the clinical judgement of the prescribing clinician, any current condition that would be a for ADHD medication, including abnormal cardiovascular examination (i.e., BP>95th percentile (for stimulants) and low blood pressure for guanfacine/clonidine as well as tachycardia ) or any conditions that should be treated before starting pharmacological treatment for ADHD such as alcohol/substance dependence, active psychosis, and active mania
  • Immediate risk to self or others
Terms in these criteria, in plain language(3)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

DSM diagnostic criteria

The American Psychiatric Association’s manual of mental health diagnoses. DSM-5 (2013, revised as DSM-5-TR in 2022) replaced DSM-IV, and some studies still name the older edition. “Meets DSM criteria for …” means diagnosed by that edition’s diagnostic criteria, usually by a clinician in an interview.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

Interventions

  • OtherPETRA decision-aid tool

    The PETRA decision-aid tool will use personalised data as well as data from meta-analysis to provide three best choices of ADHD medication. This will aid shared decision-making between clinician and patient.

  • OtherBest-evidence decision-support tool

    The output for this arm will look the same as the PETRA tool, providing three top choices of medication, each with respective pros and cons and margin of statistical uncertainty. However, the output of this tool will instead indicate the side effects that any medication is likely to cause, or not cause, based on population average data, regardless of the patients' individual characteristics.
