The Cognitive Behavioural Assessment-2.0 (CBA-2.0) Primary Scales is an automated assessment package investigating the cognitive-verbal response system. It consists of: (1) self-reports and questionnaires aimed at identifying and specifying patients' problems; (2) a group of programs and logical rules, implemented on personal computers, providing an editor with items, questionnaire scoring and an analysis of responses; (3) an intelligent program which analyzes the responses emerging from the questionnaires and forms hypotheses for the selection of Secondary Scales and for further assessment. The package is part of a research project aimed at reducing part of the decision-making process to an operational language and simulating behavioral therapists decisions in cases of clinical assessment.
