Spectrum Disorders

Risk of suicidal behaviour (SB) in schizophrenia spectrum disorders (SSD) is a major concern, particularly in early stages of the illness, when suicide accounts for a high number of premature deaths. Although some risk factors for SB in SSD are well understood, the extent to which personality traits may affect this risk remains unclear, which may have implications for prevention. We conducted a systematic review of previous studies indexed in MEDLINE, PsycINFO and Embase examining the relationship between personality traits and SB in samples of patients with SSD. Seven studies fulfilled predetermined selection criteria. Harm avoidance, passive-dependent, schizoid and schizotypal personality traits increased the risk of SB, while self-directedness, cooperativeness, excluding persistence and self-transcendence acted as protective factors. Although only seven studies were retrieved from three major databases after applying predetermined selection criteria, we found some evidence to support that personality issues may contribute to SB in patients with SSD. Personality traits may therefore become part of routine suicide risk assessment and interventions targeting these personality-related factors may contribute to prevention of SB in SSD.

The Impact

High levels of linguistic referential failures are associated with liability to develop schizophrenia-spectrum disorders, and it has been shown that these failures can differentiate healthy subjects, high-schizotypal and schizophrenics groups. Nevertheless, few investigations have focused on whether or not schizotypal traits in nonclinical populations can also impact linguistic reference. In Brazilian Portuguese, only one previous study (acceptability judgements task) had been conducted, and its results suggest association between schizotypal traits and a more rigid preference for assignment of specific readings to definite singular DPs. Here, we present another experimental study in Brazilian Portuguese,  a comprehension task designed to examine possible effects of schizotypal personality traits on the interpretation of definite singular DPs. The findings, in line with the previous results, support the conclusion that schizotypy does affect the interpretation of definite singular DPs in Brazilian Portuguese. Together, these two experiments suggest that schizotypal personality traits impact the integration of linguistic contextual information into the semantic meaning of definite DPs. This is  consistent with the general hypothesis that schizotypy, similarly to schizophrenia, is associated with pragmatic difficulties. Yet, our results emphasize that the impact of schizotypal traits on pragmatics can be observed even in healthy (nonclinical) speakers.

The Relationship

Schizophrenia spectrum disorders are chronic and debilitating mental illnesses characterised by both cognitive impairments and sleep deficits. In this systematic review protocol, we outline an approach to examine the available literature investigating the relationship between sleep and cognition in individuals with schizophrenia spectrum disorder.

AbstractBackgroundDespite knowing for many decades that depressive psychopathology is common in first-episode schizophrenia spectrum disorders (FES), there is limited knowledge regarding the extent and nature of such psychopathology (degree of comorbidity, caseness, severity) and its demographic, clinical, functional and treatment correlates. This study aimed to determine the pooled prevalence of depressive disorder and caseness, and the pooled mean severity of depressive symptoms, as well as the demographic, illness, functional and treatment correlates of depressive psychopathology in FES.MethodsThis systematic review, meta-analysis and meta-regression was prospectively registered (CRD42018084856) and conducted in accordance with PRISMA and MOOSE guidelines.ResultsForty studies comprising 4041 participants were included. The pooled prevalence of depressive disorder and caseness was 26.0% (seven samples, N = 855, 95% CI 22.1–30.3) and 43.9% (11 samples, N = 1312, 95% CI 30.3–58.4), respectively. The pooled mean percentage of maximum depressive symptom severity was 25.1 (38 samples, N = 3180, 95% CI 21.49–28.68). Correlates of depressive psychopathology were also found.ConclusionsAt least one-quarter of individuals with FES will experience, and therefore require treatment for, a full-threshold depressive disorder. Nearly half will experience levels of depressive symptoms that are severe enough to warrant diagnostic investigation and therefore clinical intervention – regardless of whether they actually fulfil diagnostic criteria for a depressive disorder. Depressive psychopathology is prominent in FES, manifesting not only as superimposed comorbidity, but also as an inextricable symptom domain.
