After 4 items have been administered (the minimum), the default for the NIH Toolbox CAT administration is to stop the CAT after either 12 items have been administered (the maximum) or the SE of the EAP score estimate is less than 0.3, which corresponds to a minimum reliability of 0.91. Other CATs may implement these or additional stopping rules, or may include content balancing or item exposure constraints.

The symptom scores were measured by using the COPD Assessment Test (CAT) and the m MRC dyspnea scale. Quality of life was measured by using the St. George Respiratory Questionnaire (SGRQ). Hospitalization was defined as hospitalizations resulting from disease exacerbation. The primary time points for the analysis were baseline and the end of the intervention.
The continuous variables included the 6 MWD, CAT score, and SGRQ score.

The daily real-time assessments of 3 variables were administered as a computer adaptive test (CAT) [42], which aims to estimate an examinee’s level of the construct (eg, depression) through sequentially administered items (questions), where each item is selected adaptively based on the examinee’s previous response. As a consequence, the estimate of the examinee’s level of the construct typically becomes more precise as more items are administered.

By using start rules, stop rules, estimation methods, and item selection procedures, almost any test can be turned into a CAT.
To our knowledge, the graded response model and CAT have not yet been used with the DASS-21.

For each CAT, at each possible assessment length, concordance between CAT and full-length score was measured with the Pearson correlation coefficient, root-mean-square error (RMSE), and 95% limits of agreement. RMSE is a measure of the difference between full-length CLEFT-Q scale scores and CLEFT-Q CAT scores, averaged across the population, and 95% limits of agreement demonstrate the difference between full-length CLEFT-Q scale scores and CLEFT-Q CAT scores at the individual level.

Patients were also instructed on the use of a peak expiratory flow (PEF) meter and the Chronic obstructive pulmonary disease assessment test (CAT) questionnaire, and how to record the results on a diary card. Subjects were monitored for 6 months or until they recovered from the first exacerbation (whichever was earlier).
Data recorded in the first week were not included in the analysis.

One of the biggest advantages of using modern test theory is that item properties can be used in a computerized adaptive testing (CAT) environment.
CAT refers to a process of selecting the most informative items for people responding to questionnaires.
