TLDR
The data suggest that personality profiles can be looked at in schizophrenia, that these profiles do appear stable over time, and that negative symptoms have a strong influence on profile stability and appear to be "trait-like."Abstract:
This study was performed in an effort to begin characterization of personality traits in schizophrenia. Specific concerns included personality profiles relative to normal adults, personality profile stability over time, and trait-state issues. The authors administered the NEO Personality Inventory as well as symptom ratings at two time points to 21 patients. Patients were all stabilized outpatients attending an adult continuing day treatment program and diagnosed with either schizophrenia or schizoaffective disorder. Personality profiles were determined for all patients. Compared with a normal adult sample, this sample's scores on three out of five of the personality domains assessed were not distinguishable from normal adults. Test-retest correlations were highly significant over an average 28.2-week time interval. In general, the presence of positive symptoms did not appear related to NEO-PI stability, while negative symptoms did show a relationship to the stability of personality profiles. These data suggest that personality profiles can be looked at in schizophrenia, that these profiles do appear stable over time, and that negative symptoms have a strong influence on profile stability and appear to be "trait-like."read more

A systematic review of personality trait change through intervention.
TL;DR: Empirical studies identified 207 studies that had tracked changes in measures of personality traits during interventions, including true experiments and prepost change designs, and found that personality traits changed the most, and patients being treated for substance use changed the least.

The Relationship Between the Five-Factor Model of Personality and Symptoms of Clinical Disorders: A Meta-Analysis
TL;DR: A meta-analysis of 33 studies that examined the relationship between the Five-Factor Model and symptoms of clinical disorders was conducted by as mentioned in this paper, who found that the typical pattern associated with clinical disorders or measures of clinical disorder was high Neuroticism, low Conscientiousness, low Agreeableness, and low Extraversion.

Affective Traits in Schizophrenia and Schizotypy
TL;DR: Empirical studies of affective traits in individuals with schizophrenia spectrum disorders, population-based investigations of vulnerability to psychosis, and genetic and psychometric high-risk samples suggest that these traits play a role in vulnerability to schizophrenia, though they are implicated in other forms of psychopathology as well.
Journal ArticleDOI
Personality self-reports are concurrently reliable and valid during acute depressive episodes.
TL;DR: The results suggest that the effect of acute depression is to amplify somewhat the personality profile of people prone to depression, rather than regard these depression-caused changes in assessed personality trait levels as a distortion, and interpret them as accurate reflections of the current condition of the individual.

TL;DR: The data support the position that personality is stable after age 30 and show evidence of small declines in Activity, Positive Emotions, and openness to Actions that might be attributed to maturation, but none of these effects was replicated in sequential analyses.
