About this study

In the current study we will examine a specific aspect of these processes that has yet to be studied. We will test the effect that a physically effortful assignment has on the choices that a preadolescent makes using a forced choice paradigm in which the participant will be asked to choose between and carry out either a high cost-high reward option (HR) or a low cost-low reward (LR) option. The HR option will demand a significant amount of physical effort and will be paired up with a large reward as opposed to the LR option which will be less demanding physically and paired up with a small reward. The assignment will be carried out using a hand held dynamometer which measures the power produced by the participants' upper extremity.

We propose that a child with attention deficit hyperactivity disorder (ADHD) will choose a task that involves less effort despite the small reward tied to it compared to a control child who will choose the more demanding task and the larger reward.

Questions about this trial

What is this clinical trial studying?

An observational study of ADHD, run by Shaare Zedek Medical Center at 1 site in Israel.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 9 Sep 2015. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Israel. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The number of "low effort" choices of the ADHD participants compared to the number of "low effort" choices of the control participants (time frame: immediately after testing). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 9 Sep 2015.
