Buckingham, C.D. & Birtle, J. (1997). Representing the assessment
process for psychodynamic psychotherapy within a computerized model of
human classification.British Journal of Medical Psychology,
70, 1-16.
This research describes a computerised model of human classification
which has been constructed to represent the process by which
assessments are made for psychodynamic psychotherapy. The model
assigns membership grades (MGs) to clients so that the most suitable
ones have high values in the therapy category. Categories consist of a
hierarchy of components, one of which, ego strength, is analysed in
detail to demonstrate the way it has captured the psychotherapist's
knowledge. The bottom of the hierarchy represents the measurable
factors being assessed during an interview. A questionnaire was
created to gather the identified information and was completed by the
psychotherapist after each assessment. The results were fed into the
computerised model, demonstrating a high correlation between the model
MGs and the suitability ratings of the psychotherapist (r = 0.825 for
24 clients). The model has successfully identified the relevant data
involved in assessment and simulated the decision-making process of
the expert. Its cognitive validity enables decisions to be explained
which means that it has potential for therapist training and also for
enhancing the referral process, with benefits in cost effectiveness
as well as in the reduction of trauma to clients. An adapted version
measuring client improvement would give quantitative evidence for the
benefit of therapy, thereby supporting auditing and accountability.
