There is currently no information available regarding the test-retest reliability of the PEBL Continuous Performance Test (P-CPT). This psychometric information would be useful for laboratories considering adopting this attention test. Participants (N=12, 41.2% male) completed the P-CPT twice with an inter-test interval of fourteen days. The consistency of measurement for the mean response times on correct trials (r(10) = .795, p < .005) and bias (r(10) = .823, p < .001) was satisfactory. Although this small pilot study generally indicates that the test-retest reliability is good, further research is needed with a larger sample that includes individuals with Attention Deficit Hyperactivity Disorder.
