Abstract: | Abstract.— Bannister and Fransella's Grid Test of Schizophrenic Thought Disorder based on Personal Construct Theory and the concept of "loosened construing", as measurable in the scores of Intensity and Consistency between intercorrelations, has been applied to a Scandinavian sample of psychiatric patients. The validity of the test was illustrated, and a significant difference was found between a group of schizophrenics and schizophrenic borderline states and a group without schizophrenic thought disorders. The Grid Test scores were found to agree with thought disorder manifestations as evaluated in qualitative terms on the basis of cognitive and projective tests, but they did not differentiate between developmental levels of thinking corresponding to con-creteness in organic impairment versus diffuseness in schizophrenia. Thus, the concept of "loosened construing" as applied in this thought disorder test seems too unspecific. |
