Age range: 18 to 89 years Admin: Individual or group Qualification level: C An objective inventory of adult personality, the PAI assesses psychopathological syndromes and provides information relevant for clinical diagnosis, treatment planning, and screening for psychopathology. Administration time is shorter than that for similar instruments. The 344 PAI items constitute 22 nonoverlapping scales covering the constructs most relevant to a broad-based assessment of mental disorders: four validity scales, 11 clinical scales, five treatment scales, and two interpersonal scales. To facilitate interpretation and to cover the full range of complex clinical constructs, 10 scales contain conceptually derived subscales.

Age range: 8 to 16 years Admin: Individual Qualification level: C The CCTT assesses sustained attention, sequencing, and other executive functions while reducing reliance on language and diminishing the effects of cultural bias and parental verbal report.  The salient features, color and number, were chosen because these characteristics are easier than letters for children to process and recognize.  Note: Form K is the standard test form for which normative data were collected and should be used for clinical evaluation. Forms X, Y, and Z should be used in research. Stopwatch is required for administration.

Age range: 18 to 89 years Admin: Individual Qualification level: C Developed to be free from the influence of language and cultural bias, the CTT assesses sustained attention in adults. Numbered circles are printed with vivid pink or yellow backgrounds that are perceptible to color-blind individuals. For Part 1, the respondent uses a pencil to rapidly connect circles numbered 1-25 in sequence. For Part 2, the respondent rapidly connects numbered circles in sequence, but alternates between pink and yellow. The length of time to complete each trial is recorded, along with qualitative features of performance indicative of brain dysfunction, such as near-misses, prompts, number sequence errors, and color sequence errors. Note: Stopwatch is required for administration. CTT Introductory Kit:  - CTT Professional Manual  -  25 Record Forms  -  25 Administrations of the CTT Form A, Parts 1 and 2
