Product Description

Conners CPT 3

  • Krebs Attention Span Performance is an attention-related test software used to test individuals.

  • Conners CPT can help assess whether the subject suffers from Attention Deficit and Hyperactivity Disorder (ADHD), and other attention-related psychiatric conditions.

  • Conners CPT3 can provide an objective value of the individual's performance in the attention test.

  • Can help identify specific areas of concern and areas of struggle for the subject. For example, the testee may struggle with the persistence test, but can focus on impulsivity, which can provide a more macro interpretation.

  • CPT can assess individuals in an objective manner because the test of attention cannot possibly be scored by another biased individual who recognizes what the problem is.

  • CPT Report

After the subject accepts the test, relevant reports can be produced, and the scores of various indicators can be judged according to the report content, which are mainly divided into four aspects: A) Inattentiveness,  B) Impulsivity, C) Sustained Attention, D) Vigilance; And use the scores of various responses to judge the main aspect of the subject's attention problem

  • There are also two ways to present the report

  1. Assessment Reports: Provide detailed information from the scores in a single test, this report will be presented in numerical and graphical form, compare the testee's scores with the standard sample, and point out the differences between the scales

  2. Progress Reports: It is used to compare the test results of the same subject at different times, and can compare the content of 2-4 tests. These reports are very suitable for monitoring treatment.
