Social cognition has been associated with functional outcome in patients with first episode psychosis (FEP). Social cognition has also been associated with neurocognition and cognitive reserve. Although cognitive reserve, neurocognitive functioning, social cognition, and functional outcome are related, the direction of their associations is not clear. Therefore, the main aim of this study was to analyze the influence of social cognition as a mediator between cognitive reserve and cognitive domains on functioning in FEP both at baseline and at 2 years.
The sample of the study was composed of 282 FEP patients followed up for 2 years. To analyze whether social cognition mediates the influence of cognitive reserve and cognitive domains on functioning, a path analysis was performed. The statistical significance of any mediation effects was evaluated by bootstrap analysis.
At baseline, as neither cognitive reserve nor the cognitive domains studied were related to functioning, the conditions for mediation were not satisfied. Nevertheless, at 2 years of follow-up, social cognition acted as a mediator between cognitive reserve and functioning. Likewise, social cognition was a mediator between verbal memory and functional outcome. The results of the bootstrap analysis confirmed these significant mediations (95% bootstrapped CI (-10.215 to -0.337) and (-4.731 to -0.605) respectively).
Cognitive reserve and neurocognition are related to functioning, and social cognition mediates in this relationship.

Having one parent diagnosed with a severe mental disorder is considered one of the main risk factors for developing that disorder in adulthood, and it also increases the risk of a wide range of mental disorders in the offspring. The aim of this study is to compare the prevalence of several psychopathological diagnoses, the presence of prodromal symptoms, and global functioning in offspring of parents with schizophrenia or bipolar disorder and in offspring of controls at baseline and 2-year follow-up. This study included 41 offspring of parents with schizophrenia, 90 offspring of parents with bipolar disorder, and 107 offspring of controls (mean age 11.7 ± 3.2 at baseline and 13.9 ± 3.2 at follow-up). The prevalence of psychopathology and comorbidity was higher in offspring of parents with schizophrenia and offspring of parents with bipolar disorder than in offspring of controls at baseline and at 2-year follow-up. Interestingly, mood disorders were more prevalent in offspring of parents with bipolar disorder and disruptive disorders were more prevalent in offspring of parents with schizophrenia. Prodromal symptoms were more frequent in offspring of parents with schizophrenia than in offspring of controls, while the offspring of parents with bipolar disorder showed an intermediate pattern. Finally, global functioning was lower in the offspring of parents with schizophrenia than the offspring of parents with bipolar disorder and the offspring of controls. Screening patients’ children is clinically relevant, since, as a group, they have an elevated risk of developing a psychiatric disorder and of experiencing their first symptoms during childhood and adolescence.

Suicidality in childhood and adolescence is of increasing concern. The aim of this paper was to review the published literature identifying key psychosocial risk factors for suicidality in the paediatric population. A systematic two-step search was carried out following the PRISMA statement guidelines, using the terms ‘suicidality, suicide, and self-harm’ combined with terms ‘infant, child, adolescent’ according to the US National Library of Medicine and the National Institutes of Health classification of ages. Forty-four studies were included in the qualitative synthesis. The review identified three main factors that appear to increase the risk of suicidality: psychological factors (depression, anxiety, previous suicide attempt, drug and alcohol use, and other comorbid psychiatric disorders); stressful life events (family problems and peer conflicts); and personality traits (such as neuroticism and impulsivity). The evidence highlights the complexity of suicidality and points towards an interaction of factors contributing to suicidal behaviour. More information is needed to understand the complex relationship between risk factors for suicidality. Prospective studies with adequate sample sizes are needed to investigate these multiple variables of risk concurrently and over time.

Offspring of individuals with schizophrenia (SZCOff) are at an increased risk for this disorder. Neuropsychological decline is a core feature of the disorder and researchers have reported increasing impairments in cognition during the prodromal phase in high-risk adolescents. Additionally, factors like the presence of prodromal symptoms or specific behavioral patterns could predict, together with neurocognitive functioning, the risk of conversion to severe mental disorders in SCZOff. This study aims to compare the neuropsychological functioning of a sample of 41 SCZOff children and adolescents and 105 community control offspring (CCOff) and to develop a prediction model to examine whether neuropsychological functioning, clinical and behavioral factors predict subsequent risk of severe mental disorders. We collected demographic, clinical and neuropsychological data. We found significant differences between groups in working memory, speed of processing, verbal memory and learning, visual memory and intelligence quotient (IQ). The socioeconomic status, verbal memory, working memory and positive prodromal symptoms predicted a significant proportion of the dependent variable variance. In conclusion, SCZOff showed neurocognitive impairments in several neuropsychological domains compared to CCOff. Neuropsychological functioning, environmental factors and positive prodromal symptoms could predict the risk of onset of severe mental disorders in SCZOff.

BackgroundHaving one parent diagnosed with a severe mental disorder is considered one of the main risk factors for developing that disorder in adulthood and it also increases the risk of a wide range of mental disorders in the offspring from early childhood and adolescence. The aim of this study is to analyze the prevalence of several psychopathological diagnoses, the presence of prodromal symptoms and global functioning in schizophrenia offspring (SZoff) or bipolar offspring (BDoff) compared to community control offspring (CCoff) at baseline and 2-year follow-up.Methods41 SZoff, 97 BDoff and 107 CCoff between 7 and 17 years were included. Clinical assessment consisted of a clinical evaluation using the following instruments: structured interview KSADS-PL or SCID-I, semi-structured Interview for Prodromal Syndromes (SIPS) and the Children’s Global Assessment Scale (CGAS). To test between-group differences in DSM-IV diagnoses multilevel mixed-effect logistic regression models (categorical variables) or linear (continuous variables) regression models were conducted with group (SZoff, BDoff and CCoff), time (baseline or 2-year follow-up), interaction time x group, age, gender and socio-economic status as fixed variables.ResultsSignificant differences between groups were found in any lifetime axis I disorder (F=8.720; p<0.001), mood disorders (F=4.774; p=0.009), anxiety disorders (F=4.368; p=0.013), ADHD (F=21.593; p<0.001), disruptive behavioral disorders (F=10.788; p<0.001) and comorbidity (F=5.588; P=0.004). Significant differences between groups were also found in the positive (F=6.088; p=0.003), negative (F=4.423; p=0.015), disorganized (F=3.866; p=0.024) and total (F=6.394; p= 0.002) sub-scales of the SOPS and CGAS (F=11.613;p<0.001). Interestingly, mood disorders were more prevalent in BDoff and disruptive disorders were more prevalent in SZoff. Prodromal symptoms were higher in SZoff compared to CCoff, while the BPoff group showed an intermediate pattern. Finally, global functioning was lower in the SZoff group compared to BDoff and CCoff.DiscussionScreening patients’ children is clinically relevant since, as a group, they have an elevated risk of developing a psychiatric disorder and of experiencing their first symptoms during childhood and adolescence.

Antipsychotic Agents - adverse effects

Previous literature supports antipsychotics' (AP) efficacy in acute first-episode psychosis (FEP) in terms of symptomatology and functioning but also a cognitive detrimental effect. However, regarding functional recovery in stabilised patients, these effects are not clear. Therefore, the main aim of this study is to investigate dopaminergic/anticholinergic burden of (AP) on psychosocial functioning in FEP. We also examined whether cognitive impairment may mediate these effects on functioning.
A total of 157 FEP participants were assessed at study entry, and at 2 months and 2 years after remission of the acute episode. The primary outcomes were social functioning as measured by the functioning assessment short test (FAST). Cognitive domains were assessed as potential mediators. Dopaminergic and anticholinergic AP burden on 2-year psychosocial functioning [measured with chlorpromazine (CPZ) and drug burden index] were independent variables. Secondary outcomes were clinical and socio-demographic variables.
Mediation analysis found a statistical but not meaningful contribution of dopaminergic receptor blockade burden to worse functioning mediated by cognition (for every 600 CPZ equivalent points, 2-year FAST score increased 1.38 points). Regarding verbal memory and attention, there was an indirect effect of CPZ burden on FAST (
= 0.0045, 95% CI 0.0011-0.0091) and (
= 0.0026, 95% CI 0.0001-0.0006) respectively. However, only verbal memory
analyses showed a significant indirect effect (
= 0.009, 95% CI 0.033-0.0151) adding premorbid IQ as covariate. We did not find significant results for anticholinergic burden.
CPZ dose effect over functioning is mediated by verbal memory but this association appears barely relevant.

The objective of this study is to investigate cognitive performance in a first-episode psychosis sample, when stratifying the interaction by cannabis use and familial or non-familial psychosis. Hierarchical-regression models were used to analyse this association in a sample of 268 first-episode psychosis patients and 237 controls. We found that cannabis use was associated with worse working memory, regardless of family history. However, cannabis use was clearly associated with worse cognitive performance in patients with no family history of psychosis, in cognitive domains including verbal memory, executive function and global cognitive index, whereas cannabis users with a family history of psychosis performed better in these domains. The main finding of the study is that there is an interaction between cannabis use and a family history of psychosis in the areas of verbal memory, executive function and global cognition: that is, cannabis use is associated with a better performance in patients with a family history of psychosis and a worse performance in those with no family history of psychosis. In order to confirm this hypothesis, future research should explore the actual expression of the endocannabinoid system in patients with and without a family history of psychosis.

Development and psychometric properties of the “Suicidality: Treatment Occurring in Paediatrics (STOP) Risk and Resilience Factors Scales” in adolescents
2020
Suicidality in the child and adolescent population is a major public health concern. There is, however, a lack of developmentally sensitive valid and reliable instruments that can capture data on risk, and clinical and psychosocial mediators of suicidality in young people. In this study, we aimed to develop and assess the validity of instruments evaluating the psychosocial risk and protective factors for suicidal behaviours in the adolescent population. In Phase 1, based on a systematic literature review of suicidality, focus groups, and expert panel advice, the risk factors and protective factors (resilience factors) were identified and the adolescent, parent, and clinician versions of the STOP-Suicidality Risk Factors Scale (STOP-SRiFS) and the Resilience Factors Scale (STOP-SReFS) were developed. Phase 2 involved instrument validation and comprised of two samples (Sample 1 and 2). Sample 1 consisted of 87 adolescents, their parents/carers, and clinicians from the various participating centres, and Sample 2 consisted of three sub-samples: adolescents (n = 259) who completed STOP-SRiFS and/or the STOP-SReFS scales, parents (n = 213) who completed one or both of the scales, and the clinicians who completed the scales (n = 254). The STOP-SRiFS demonstrated a good construct validity—the Cronbach Alpha for the adolescent (α = 0.864), parent (α = 0.842), and clinician (α = 0.722) versions of the scale. Test–retest reliability, inter-rater reliability, and content validity were good for all three versions of the STOP-SRiFS. The sub-scales generated using Exploratory Factor Analysis (EFA) were the (1) anxiety and depression risk, (2) substance misuse risk, (3) interpersonal risk, (4) chronic risk, and (5) risk due to life events. For the STOP-SRiFS, statistically significant correlations were found between the Columbia-Suicide Severity Rating Scale (C-SSRS) total score and the adolescent, parent, and clinical versions of the STOP-SRiFS sub-scale scores. The STOP-SRiFS showed good psychometric properties. This study demonstrated a good construct validity for the STOP-SReFS—the Cronbach Alpha for the three versions were good (adolescent: α = 0.775; parent: α = 0.808; α = clinician: 0.808). EFA for the adolescent version of the STOP-SReFS, which consists of 9 resilience factors domains, generated two factors (1) interpersonal resilience and (2) cognitive resilience. The STOP-SReFS Cognitive Resilience sub-scale for the adolescent was negatively correlated (r = − 0.275) with the C-SSRS total score, showing that there was lower suicidality in those with greater Cognitive Resilience. The STOP-SReFS Interpersonal resilience sub-scale correlations were all negative, but none of them were significantly different to the C-SSRS total scores for either the adolescent, parent, or clinician versions of the scales. This is not surprising, because the items in this sub-scale capture a much larger time-scale, compared to the C-SSRS rating period. The STOP-SReFS showed good psychometric properties. The STOP-SRiFS and STOP-SReFS are instruments that can be used in future studies about suicidality in children and adolescents.

A developmental approach to dimensional expression of psychopathology in child and adolescent offspring of parents with bipolar disorder
2017
The aim of this is to describe psychopathology, functioning and symptom dimensions accounting for subthreshold manifestations and developmental status in child and adolescent offspring of parents with bipolar disorder (“high-risk offspring”). The study population comprised 90 high-risk offspring (HR-offspring) and 107 offspring of community control parents (CC-offspring). Direct clinical observations and parental and offspring reports based on selected standardized clinical scales were used to assess offspring threshold and subthreshold diagnoses, symptoms and functioning. All outcomes were compared between the whole HR-offspring and CC-offspring samples and then by developmental status. After controlling for potential confounders, HR-offspring showed significantly poorer adjustment for childhood (
r
= 0.18,
p
= 0.014) and adolescence (
r
= 0.21,
p
= 0.048) than CC-offspring, as well as more emotional problems (
r
= 0.24,
p
= 0.001) and higher depression scores (
r
= 0.16,
p
= 0.021). As for differences in lifetime categorical diagnoses (threshold and subthreshold) between HR-offspring and CC-offspring, the prevalence of disruptive disorders was higher in pre-pubertal HR-offspring (OR 12.78 [1.45–112.42]), while prevalence of mood disorders was higher in post-pubertal HR-offspring (OR 3.39 [1.14–10.06]). Post-pubertal HR-offspring presented more prodromal (
r
= 0.40,
p
= 0.001), negative (
r
= 0.38,
p
= 0.002), manic (
r
= 0.22,
p
= 0.035) and depressive (
r
= 0.23,
p
= 0.015) symptoms than pre-pubertal HR-offspring, as well as more peer relationship problems (
r
= 0.31,
p
= 0.004), poorer childhood adjustment (
r
= 0.22,
p
= 0.044) and worse current psychosocial functioning (
r
= 0.27,
p
= 0.04). Externalizing psychopathology is more prevalent in pre-pubertal HR-offspring, while depressive and prodromal symptoms leading to functional impairment are more prominent in post-pubertal HR-offspring. Developmental approaches and dimensional measures may be useful for identifying children at high risk of developing bipolar disorder and help guide specific preventive strategies.

The aim of the study was to analyze changes in functional adjustment from childhood to 2 years after the first episode of psychosis (FEP) in patients with early-onset schizophrenia spectrum disorders (SSD) and affective psychoses (AFP) and a good or intermediate level of premorbid adjustment. We followed 106 adolescents (aged 12–17 years) with FEP for 2 years after recruitment. Premorbid adjustment in childhood was assessed in 98 patients with the childhood subscale of the Cannon-Spoor Premorbid Adjustment Scale (c-PAS). Global functioning was assessed 2 years after the FEP with the Children’s Global Assessment Scale (c-GAS) or the Global Assessment of Functioning scale (GAF), as appropriate. Functional deterioration was defined as a downward shift in the level of functional adjustment from childhood to 2 years after the FEP. In patients with good or intermediate premorbid adjustment, functional deterioration was observed in 28.2 % (26.5 % of the AFP group, 29.4 % of the SSD group). Longer duration of untreated psychosis (Beta = 0.01;
P
= 0.01) and higher symptom severity at the FEP, as measured with the Clinical Global Impression Scale (Beta = 1.12;
P
= 0.02), significantly predicted the presence of functional deterioration, accounting for 21.4 % of the variance. Irrespective of diagnosis (SSD or AFP), almost one-third of adolescents with FEP and good or intermediate premorbid adjustment showed functional deterioration from the premorbid period to 2 years after the FEP.
