The Color Trails Test (CTT) assesses sustained attention in adults, and was developed to be free from the influence of language and cultural bias.
The CTT retains the sensitivity and specificity of the original Trail Making Test (TMT) but substitutes color for letters, making it more suitable in cross-cultural and special needs contexts. Instructions may be presented either verbally or with visual cues.
The Color Trails Test Form A Trial 2 Test Sheet contains a practice trial on one side, and the test trial on the opposite side.
The respondent is instructed to rapidly draw a line between numbered circles, maintaining the sequence, but alternating between pink and yellow colours. For example, they would need to draw a line from Pink 1 to Yellow 2 (avoiding Pink 2). The respondent would have completed the practice trial prior. The examiner will record the number of near misses, prompts, colour sequence errors and number sequence errors made by the respondent.
