I am currently planning a study looking into nutritional supplement effects on ADHD children (aged 7-10yo).
I want to empirically measure the attention of ADHD and healthy control children at baseline, midline (2wks) and end (4wks) of intervention. I found that the Conner's Continuous Performance Test would be perfect for this... however, not so perfect at £760! I came across a free software download which has a large testing battery included in it called PEBL - has anybody used this, and in particular the Continuous Performance Test within it? I am slightly worried there is no normative data for the PEBL software, unlike Conner's which there is, but if I am comparing to my own control group this is not a major problem.
Any alternative suggestions would be great and any input to my research is always welcome, thanks!
Not sure about the difference in cost, but have you considered the TOVA (Test of Variables of Attention)?

On their website, they have links to technical reports, if that helps. I will also attach an article that might be helpful.
you can continue inthis study for comparing with control group in good
enviroments ,so ther is not major problem.
I have a new CPT program, a new one. It is not so expensive as it is not commercial yet. You can ask me for detail or read one of my paper describe the construction of the test. The second paper describes a research when the test was used.

I am looking forward to hearing from you.

Have you considered the BrainResource WebNeuro or IntegNeuro assessments? They provide a CPT along with other methods of EF. Worth looking into.

Hello Katie,
First, I have an ownership interest in the test site that I will mention. So this post may not get shown. CogQuiz.com will soon have a set of tests including a CPT. The CPTs are in someways different from Go/NoGo tasks but not that important. Both have been criticized in numerous papers as assessments of attention. They are in my opinion pretty good. The cogquiz test allows you to manipulate the frequency and presentation rate of targets and non-targets. The typical CPTs have a single target in central focus, no distractors, and no motivation (e.g., rewards and punishments for hits and misses). See faces in the CogQuiz addressing these problems. You can make virtually any commercially available CPT in the CogQuiz CPT. Good luck. As for PEBLs, there is a reason it is free.
