The modified completion test (MCT) based on the stories by H. Ebbinghaus enables to assess cognitive functions in situation close to a real-life task with an affective load (Burlakova,2016,2020). MCT includes the following stages: 1) filling the gaps in the story; 2) reading and retelling; 3) making up a continuation and a title; 4) retelling the story and its continuation after 30–40 minutes.

The objective was to research diagnostical potential of the second stage of MCT for patients suffering from paranoid schizophrenia with hallucinatory syndrome.

The study included 42 patients (28 female, 14 male) with schizophrenia (disease onset at least 5–7 years ago), aged from 19 to 51 (average age 35±8), receiving treatment. Control group consisted of 44 people (average age 37±6), never sought psychiatric help, never diagnosed with any mental disorders. Groups were organized to be equal in gender proportions, age, and educational level.

In comparison to the control group, the psychiatric patients demonstrated: 1) lower connectedness in narration, lower ability to reproduce main elements of the plot; 2) unusual logic in introduction of new details, extensiveness of such details; 3) lower integrity of mnestic functions, lower ability to maintain concentration. The clinical group: 1) imposed on the text principally different logic, subjectively significant, yet far from the original context; 2) suddenly introduced of new ideas; 3) had confabulations; 4) were altiloquent.

The stage of retelling enables to assess semantic memory, regulatory functions, connectedness of the narration, cogitation and to examine cognitive functions in the context of patient’s personality.
