The cognitive model of negative symptoms in schizophrenia: a hierarchical component model with PLS-SEM.
Open accessAbstract
The cognitive model of negative symptoms suggests that some dysfunctional beliefs mediate the relationship between neurocognitive deficits and negative symptoms and disability. This study tested the hypothesis that dysfunctional performance beliefs mediate neurocognitive deficits, negative symptoms, and disability. We used a hierarchal component model with 85 men patients diagnosed with chronic schizophrenia. Results showed a moderate to strong correlation between dysfunctional performance beliefs, neurocognitive deficits, negative symptoms, and disability. These results support the Hierarchal component model (HCM) of the cognitive model of negative symptoms. Our results indicated that the disability in schizophrenia is mediated through dysfunctional performance beliefs, neurocognitive deficits, and negative symptoms pathway. Further, dysfunctional performance beliefs have a crucial role in this pathway. Therefore, targeting this vicious cycle of dysfunctional beliefs can improve disability in patients with schizophrenia.

Relevant contributing psychological processes in development of negative symptoms seem to be demoralization due to low expectancies for pleasure or success, internalized stigma, lack of participation and activities, and maladaptive coping responses such as social anhedonia and substance abuse.
“Relevant contributing psychological processes in the development of negative symptoms thereby seem to be a demoralization due to patients’ low expectancies for pleasure or success (64, 86), internalized stigma (87), a lack of participation and activities (88), and maladaptive coping responses such as social anhedonia and substance abuse to deal with aversive internal and external experiences (89).”
From Developing a mechanism-based therapy for acute psychiatric inpatients with psychotic symptoms: an Intervention Mapping approach (2023) · cites this paper as [64]
The Discussion (page unavailable) describes negative symptoms as a maladaptive mechanism that protects against anticipated pain and rejection from activity, supporting the coping-process part of the cited clause. The Introduction lists anhedonia and asociality as negative symptoms, but our copy does not identify social anhedonia or substance abuse as coping responses to aversive experiences. (LLM, conf=0.84)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
