Family communication with teens at clinical high-risk for psychosis or bipolar disorder

Review of Major Social Determinants of Health in Schizophrenia-Spectrum Psychotic Disorders: I. Clinical Outcomes

BACKGROUND

Social determinants of health (SDoHs) are receiving growing attention and are particularly relevant to persons with schizophrenia-spectrum psychotic disorders (SSPDs), considering their heightened risk of comorbidities, cognitive and functional decline, and early mortality. Yet, we did not find any comprehensive review of multiple SDoHs in SSPD.

STUDY DESIGN

We conducted a scoping review of meta-analyses and systematic reviews of nine major SDoHs in SSPD.

STUDY RESULTS

Childhood abuse, parental psychopathology, parental communication problems, bullying, and urban settings with lower socioeconomic status were major risk factors for the greater incidence of SSPD and/or worse health. Social network size was inversely associated with overall psychopathology and negative symptoms. Experiences of racial/ethnic discrimination correlated with the prevalence of psychotic symptoms and experiences. Compared to native populations, the risk of psychosis was higher in immigrants, refugees, and asylees. Social fragmentation was associated with an increased prevalence of schizophrenia. Homeless populations had a 30-fold higher prevalence of schizophrenia than the general population. Seriously mentally ill people were 2.7 times more likely to report food insecurity than controls. The prevalence of non-affective psychosis in prisoners was 2.0%-6.5%, compared to 0.3% in the general population. Certain potentially positive factors like family and community resilience remain poorly studied.

CONCLUSIONS

SDoHs are associated with higher rates of and worse outcomes in SSPD. Well-designed longitudinal studies are needed to understand SDoHs' contribution to health in persons with SSPD, to develop interventions, and to implement changes in clinical care and public health policies that would reduce adverse health impacts of SDoHs. Positive SDoHs deserve greater attention.

Family communication and the efficacy of family focused therapy in individuals at clinical high risk for psychosis with comorbid anxiety

AIM

Comorbid anxiety disorder is related to greater illness severity among individuals at clinical high risk (CHR) for psychosis, but its potential role in moderating response to Family Focused Therapy (FFT) for CHR is unexamined. We investigated whether comorbid anxiety disorder in CHR individuals is associated with less constructive communication during family problem-solving interactions, whether their communication skills differentially improve after FFT, and whether FFT is effective in reducing anxiety in this population.

METHODS

Individuals recruited into the second phase of the 8-site North American Prodrome Longitudinal Study (NAPLS2) participated (N = 129). They were randomly assigned to 18-sessions of FFT-CHR or three-sessions of Enhanced Care (EC). Participants completed a diagnostic interview at pre-treatment, a family interaction task at pre-treatment and 6-months, and a self-report anxiety measure at pretreatment, 6 and 12-months.

RESULTS

Individuals at CHR with comorbid anxiety engaged in more negative and fewer positive behaviours during family problem-solving interactions at pre-treatment than did those without comorbid anxiety. There was a significant interaction between anxiety diagnosis and time on interactional behaviour scores, such that individuals at CHR with an anxiety diagnosis showed a greater decrease in negative behaviours and increase in positive behaviours from baseline to 6-months than those without anxiety disorder(s) regardless of treatment condition. However, individuals' self-reported anxiety symptoms decreased more in FFT-CHR than in EC from pre-treatment to 12-month follow-up, regardless of anxiety diagnoses.

CONCLUSIONS

Individuals at CHR with symptoms of anxiety benefit from family interventions in showing reductions in anxiety and improvements in family communication.

Family-focused therapy for individuals at high clinical risk for psychosis: A confirmatory efficacy trial

AIMS

Young people with attenuated psychotic symptoms (APS), brief intermittent psychosis, and/or genetic risk and functional deterioration are at high risk for developing psychotic disorders. In a prior trial, family-focused therapy for clinical high risk youth (FFT-CHR) was more effective than brief psychoeducation in reducing APS severity over 6 months. This 7-site trial will compare the efficacy of FFT-CHR to a psychoeducational and supportive intervention (enhanced care) on APS and social functioning in CHR individuals over 18 months.

METHODS

Participants (N = 220, ages 13-25 years) with a CHR syndrome will be randomly assigned to FFT-CHR (18 1-h sessions of family psychoeducation and communication/problem-solving skills training) or enhanced care (3 1-h family psychoeducational sessions followed by 5 individual support sessions), both given over 6 months. Participants will rate their weekly progress during treatment using a mobile-enhanced online platform. Family communication will be assessed in a laboratory interactional task at baseline and post-treatment. Independent evaluators will assess APS (primary outcome) and psychosocial functioning (secondary outcome) every 6 months over 18 months.

RESULTS

We hypothesize that, compared to enhanced care, FFT-CHR will be associated with greater improvements in APS and psychosocial functioning over 18 months. Secondarily, improvements in family communication over 6 months will mediate the relationship between treatment condition and primary and secondary outcomes over 18 months. The effects of FFT-CHR are predicted to be greater in individuals with higher baseline risk for psychosis conversion.

CONCLUSIONS

Results of the trial will inform treatment guidelines for individuals at high risk for psychosis.

The relationship between stress responding in family context and stress sensitivity with sleep dysfunction in individuals at clinical high-risk for psychosis

Stress and sleep have been implicated in the etiology of psychosis, and literature suggests they are closely related. Two distinct domains of stress associated with sleep dysfunction in the general population are responsivity to environmental stressors and stress sensitivity. However, to date, no research has examined relationships between these stress domains and sleep dysfunction in individuals at clinical high-risk (CHR) for psychosis. A total of 57 CHR (mean age = 18.89, SD = 1.82) and 61 healthy control (HC; mean age = 18.34, SD = 2.41) adolescents and young adults completed a measure of emerging stress intolerance. A subset of participants (CHR = 50, HC = 49) completed a measure indexing responsivity to family stressors - an integral context for this developmental stage overlapping with the psychosis-risk period. Sleep efficiency, continuity, and duration were objectively assessed by actigraphy (CHR = 38, HC = 36). Partial correlations with age and sex as covariates were conducted in both groups separately to examine relationships between stress and sleep. Results indicated that automatic maladaptive responsivity to family stressors was associated with disrupted sleep in the CHR but not HC group. Specifically, greater involuntary engagement was associated with poorer sleep efficiency (r = -.42) but not sleep continuity (r = 0.31) and duration (r = .-19). Interestingly, both adaptative and maladaptive voluntary responses to stressors (engagement and disengagement coping) were not associated with sleep. Finally, impaired stress tolerance was associated with sleep efficiency (r = -0.47), continuity (r = 0.37), and duration (r = -0.43). Taken together, findings provided important groundwork for understanding the role of the relationship between involuntary maladaptive responsivity to family stressors and stress sensitivity with sleep in psychosis etiology.

Individuals at ultra-high risk of psychosis and first-degree relatives of patients with schizophreniaexperience impaired family functionality and social support deficit in comparison to healthy controls

AIM

The present study was designed to assess the role of family function and social support in the context of different phases of schizophrenia.

METHODS

First-episode patients with experiences of schizophrenia (FEP), ultra-high risk for psychosis (UHR), first-degree relatives (FDR) of patients with experiences of schizophrenia, and healthy controls (HC) (40 per group) were subjected to in-person clinical interviews. The results of these interviews were then used to gauge social support and family function using the Perceived Social Support Scale (PSSS) and the Family Adaptability and Cohesion Scales (FACESII-CV). Data were analyzed through ANCOVA, correlation analysis and logistic regression analyses.

RESULTS

We found that family function and social support showed a approximately gradual downward trend through the HC, FDR, UHR, and FEP groups but no significant differences were found in the family function of the FDR, UHR and FDR group. Logistic regression analyses indicated that UHR group patients exhibited decreased family support and family cohesion relative to members of the HC group, but had greater perceived social support than did members of the FEP group. Results for members of the FDR group were in line with those of members of the UHR group.

CONCLUSIONS

These findings suggested that both UHR and FDR individuals experience impaired family functionality and social support which expanded the understanding of the psychological characteristics of the prodromal period of schizophrenia. Further explorations are warranted to develop optimal psychosocial interventions.

Family environmental factors in at-risk mental states for psychosis

The family environment represents an important psychosocial factor that impacts psychosis prognosis, but little is known about its effect on the at-risk stages of psychosis. This study presents a comprehensive review and summarizes the state of the art of study on the wide range of family factors related to family functioning in the At-Risk Mental State (ARMS) for psychosis, as well as family interventions in ARMS individuals. Publications were retrieved by an extensive search on MEDLINE, PsycINFO and SCOPUS (1990-2020). Expressed Emotion is the most studied variable in ARMS literature, but there is scarce evidence of the role of other significant family factors at the ARMS stage. Overall, high Expressed Emotion did not appear to be reactive to ARMS patients' poor clinical status. However, initial evidence has suggested that relatives' beliefs about the disorder may play a significant role, either as mediators of these relationships or as predictors of Expressed Emotion. Available literature yet to yield a consistent pattern of findings on the association between Expressed Emotion or other family functioning indicators and negative outcomes, but some longitudinal studies highlight the greater potential for the protective effects of positive family environments at the ARMS stage. Family-based interventions have demonstrated benefits for both ARMS individuals and family dynamics. An increased focus on the impact of the at-risk stage of illness on relatives' mental well-being is required to provide family support based on their needs and to clarify the mechanisms leading to dysfunctional family dynamics during the critical ARMS period.

Annual Research Review: Prevention of psychosis in adolescents - systematic review and meta-analysis of advances in detection, prognosis and intervention

BACKGROUND

The clinical high-risk state for psychosis (CHR-P) paradigm has facilitated the implementation of psychosis prevention into clinical practice; however, advancements in adolescent CHR-P populations are less established.

METHODS

We performed a PRISMA/MOOSE-compliant systematic review of the Web of Science database, from inception until 7 October 2019, to identify original studies conducted in CHR-P children and adolescents (mean age <18 years). Findings were systematically appraised around core themes: detection, prognosis and intervention. We performed meta-analyses (employing Q statistics and I ² test) regarding the proportion of CHR-P subgroups, the prevalence of baseline comorbid mental disorders, the risk of psychosis onset and the type of interventions received at baseline. Quality assessment and publication bias were also analysed.

RESULTS

Eighty-seven articles were included (n = 4,667 CHR-P individuals). Quality of studies ranged from 3.5 to 8 (median 5.5) on a modified Newcastle-Ottawa scale. Detection: Individuals were aged 15.6 ± 1.2 years (51.5% males), mostly (83%) presenting with attenuated positive psychotic symptoms. CHR-P psychometric accuracy improved when caregivers served as additional informants. Comorbid mood (46.4%) and anxiety (31.4%) disorders were highly prevalent. Functioning and cognition were impaired. Neurobiological studies were inconclusive.

PROGNOSIS

Risk for psychosis was 10.4% (95%CI: 5.8%-18.1%) at 6 months, 20% (95%CI: 15%-26%) at 12 months, 23% (95%CI: 18%-29%) at 24 months and 23.3% (95%CI: 17.3%-30.7%) at ≥36 months.

INTERVENTIONS

There was not enough evidence to recommend one specific treatment (including cognitive behavioural therapy) over the others (including control conditions) to prevent the transition to psychosis in this population. Randomised controlled trials suggested that family interventions, cognitive remediation and fish oil supplementation may improve cognition, symptoms and functioning. At baseline, 30% of CHR-P adolescents were prescribed antipsychotics and 60% received psychotherapy.

CONCLUSIONS

It is possible to detect and formulate a group-level prognosis in adolescents at risk for psychosis. Future interventional research is required.

Depression, family interaction and family intervention in adolescents at clinical-high risk for psychosis

AIM

The relationship between family behaviour and depression in adolescents at clinical high risk (CHR) for psychosis remains understudied despite high rates of depression in this population. This study examines the relationship between family problem-solving behaviours and depression in CHR adolescents and the impact of family interventions targeting subthreshold symptoms of psychosis on reducing symptoms of depression over 2-years.

METHODS

Participants were a subset of the North American Prodrome Longitudinal Study who were randomized to 6-months of family focused therapy for individuals at CHR or family psychoeducational treatment. We evaluated the relationship between communication during family conflict discussion and adolescents' symptoms of depression before treatment. At follow-up assessments the family treatment groups were compared on depression. Finally, we compared those in family treatment with matched controls.

RESULTS

Adolescents' constructive communication was associated with less severe symptoms of depression before treatment. Symptoms of depression improved for adolescents in both family treatment groups. However, there were no significant group by treatment interactions. When adolescents who participated in either type of family intervention were compared to CHR adolescent controls, symptoms of depression improved for adolescents in treatment and control groups, but there were no significant time by treatment interactions.

CONCLUSIONS

The communication skills of CHR adolescents are related to both depression and their parents' communication skills pre-treatment. However, reductions in depression over the course of the treatment trial cannot be attributed to family treatment. It is imperative to incorporate interventions that directly target depression into future family treatment studies.

The Critical Need for Help-Seeking Controls in Clinical High-Risk Research

Despite rapidly growing knowledge of the clinical high-risk (CHR) state for psychosis, the vast majority of case-control studies have relied on healthy volunteers as a reference point for drawing inferences about the CHR construct. Researchers have long recognized that results generated from this design are limited by significant interpretive concerns, yet little attention has been given to how these concerns affect the growing field of CHR research. We argue that overreliance on healthy controls in CHR research threatens the validity of inferences concerning group differences, hinders advances in understanding the development of psychosis, and limits clinical progress. We suggest that the combined use of healthy and help-seeking (i.e., psychiatric) controls is a necessary step for the next generation of CHR research. We then evaluate methods for help-seeking control studies, identify the available CHR studies that have used such designs, discuss select findings in this literature, and offer recommendations for research.
