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.

The study demonstrates potential of the modified completion test (MCT) (text by H. Ebbinghaus) for diagnostics of patients with schizophrenia. MCT includes four 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 half an hour (Burlakova,2020).

The objective was to research diagnostical potential of the first 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.

The psychiatric patients in comparison to the control group: 1) accomplished the task slower; 2) although instructed to fill the gaps in succession, often violated the instruction and demonstrated orientation on specific fragments rather than on the whole; 3) had lower efficiency: ˜5% of the clinical group did the task without mistakes; 4) chose strategies of interacting with the text not detected in the control group: a) did not fill several gaps, b) added words outside the gaps, and c) crossed out fragments of the text; 5) filled the gaps with words inadequate emotionally, semantically and/or logically.

Comparative analysis demonstrated that already on the first stage, the method proves informative in pathopsychological assessment.

The formation of thinking in ontogenesis follows the line of progressive differentiation and integration of the representations of objects, events, and relationships. The same is true for the development of mentalization ability, conceived as a thought process in the area of social interactions.

The purpose of the study was to compare the particularities of thought processes when dealing with different types of material: physical objects (operational thinking) and social situations (mentalization).

40 inpatients with schizotypal personality disorder, 40 inpatients with paranoid schizophrenia and 40 controls took part in the study. The Objects Sorting Test was used to assess operational thinking. The mentalization ability was assessed using two SCOR-S scales for Thematic Apperception Test: Complexity of representations of people and Understanding of social causality.

The results of correlation analysis support the existence of the reverse links between the impairments of operational thinking and both the complexity of representations of people (r=-.36, р<.001) and the understanding of social causality (r=-.38, р<.001). It is supported by the qualitative analysis, where inpatients with thought distortions, characterized by arbitrary generalizations, are inclined to make similar errors in the reasoning about the mental states, ignoring the conventional explanations and relying on their own emotional impression and etc.

The limitations of the operational thinking as reflected in the inability to form adequate generalizations on the basis of socially predefined attributes of meaning are closely related to the ability of differentiation, integration and causal explanation of meaningful aspects or social situations.

Formal thought disorder (FTD) and social functioning impairments are core symptoms of schizophrenia. Although both have been observed for over a century, the strength of the relationship between FTD and social functioning remains unclear. Furthermore, a variety of methodological approaches have been used to assess these constructs—which may contribute to inconsistency in reported associations. This meta-analysis aimed to: (a) systematically test the relationship between FTD and social functioning and (b) determine if the methodology used to assess FTD and/or social functioning moderates this relationship.

Following Preferred Reporting Items for Systematic reviews and Meta-analyses (PRISMA) guidelines, a targeted literature search was conducted on studies examining the relationship between FTD and social functioning. Correlations were extracted and used to calculate weighted mean effect sizes using a random effects model.

A total of 1,478 participants across 13 unique studies were included in this meta-analysis. A small-medium inverse association (r = −0.23, p < 0.001) was observed between FTD and social functioning. Although heterogeneity analyses produced a significant Q-statistic (Q = 52.77, p = <0.001), the relationship between FTD and social functioning was not moderated by methodology, study quality, demographic variables, or clinical factors.

Findings illustrate a negative association between FTD and social functioning. Despite differences in the methodological approach used and type of information assessed, measurement type and clinical factors did not moderate the relationship between FTD and social functioning. Future studies should explore whether other variables, such as cognitive processes (e.g., social cognition), may account for variability in associations between these constructs.

Poor social cognition is prevalent in schizophrenia spectrum disorders. Some authors argue that these effects are symptom-specific and that socio-cognitive difficulties (e.g. theory of mind) are strongly associated with thought disorder and symptoms of disorganisation.

The current review tests the strength of this association.

We meta-analysed studies published between 1980 and 2016 that tested the association between social cognition and these symptoms in schizophrenia spectrum disorders.

Our search (PsycINFO, MEDLINE and Web of Science) identified 123 studies (N = 9107). Overall effect size as r = −0.313, indicating a moderate association between symptoms and social cognition. Subanalyses yielded a moderate association between symptoms and theory of mind (r = −0.349) and emotion recognition (r = −0.334), but smaller effect sizes for social perception (r = −0.188), emotion regulation (r = −0.169) and attributional biases (r = −0.143).

The association is interpreted within models of communication that highlight the importance of mentalisation and processing of partner-specific cues in conversational alignment and grounding.

Most empirical studies into the covariance structure of psychopathology have been confined to adults. This work is not developmentally informed as the meaning, age-of-onset, persistence and expression of disorders differ across the lifespan. This study investigates the underlying structure of adolescent psychopathology and associations between the psychopathological dimensions and sex and personality risk profiles for substance misuse and mental health problems.

This study analyzed data from 2175 adolescents aged 13.3 years. Five dimensional models were tested using confirmatory factor analysis and the external validity was examined using a multiple-indicators multiple-causes model.

A modified bifactor model, with three correlated specific factors (internalizing, externalizing, thought disorder) and one general psychopathology factor, provided the best fit to the data. Females reported higher mean levels of internalizing, and males reported higher mean levels of externalizing. No significant sex differences emerged in liability to thought disorder or general psychopathology. Liability to internalizing, externalizing, thought disorder and general psychopathology was characterized by a number of differences in personality profiles.

This study is the first to identify a bifactor model including a specific thought disorder factor. The findings highlight the utility of transdiagnostic treatment approaches and the importance of restructuring psychopathology in an empirically based manner.

Thought disorder has been proposed as an indicator of schizotypy, which is considered to be necessary but not sufficient for the development of schizophrenia. It is unclear whether thought disorder is an indicator of susceptibility (i.e. an endophenotype) for schizophrenia. The goal of the present study was to elucidate the role of thought disorder in relation to schizotypy by examining its presence in high-risk individuals during mid-childhood.

The sample consisted of 265 subjects drawn from the New York High-Risk Project. Individuals at high risk for schizophrenia (i.e. offspring of parents with schizophrenia) were compared with individuals at low risk for schizophrenia (i.e. offspring of parents with affective disorder or offspring of psychiatrically normal parents). Videotaped interviews were rated for thought disorder using the Scale for the Assessment of Thought, Language, and Communication (TLC). The same subjects were administered diagnostic interviews in late adolescence/early adulthood.

Although positive thought disorder was equally present in subjects with affective and non-affective psychoses, negative thought disorder (namely, poverty of speech and poverty of content of speech) was elevated only in subjects with schizophrenia-related psychosis. Logistic regression analyses revealed that negative thought disorder added to the prediction of schizophrenia-related psychosis outcomes over and above positive thought disorder.

These findings suggest that negative thought disorder may have a specific association with schizotypy, rather than a more general association with psychosis. The findings also support consideration of negative thought disorder as an endophenotypic indicator of a schizophrenia diathesis.
