Be outspoken and overcome stigmatizing thoughts (BOOST): a group treatment for internalized stigma in first-episode psychosis

Diverse elements comprising studies of peer support complicate evidence synthesis

BACKGROUND

Innovative approaches to care, such as peer support, are needed to address the substantial and frequently unmet needs of people with serious mental illnesses such as schizophrenia. Although peer support services continue to expand in mental healthcare, findings of effectiveness from systematic reviews are mixed. However, the studies evaluated in these reviews consisted of diverse elements which the review methods neglected to consider.

AIMS

This review aims to demonstrate the substantial diversity in intervention components and measured outcomes among studies of peer support and lay the groundwork for more focused reviews of individual intervention components.

METHODS

As part of a realist review of the literature, here we synthesize evidence in a way that examines the substantial diversity in intervention components and measured outcomes comprising studies of peer support.

RESULTS

Seven categories of outcomes were represented, including recovery, symptoms and functioning, and care utilization. Importantly, seven distinct intervention components were represented in 26 studies: "being there," assistance in self-management, linkage to clinical care and community resources, social and emotional support, ongoing support, explicit utilization of shared lived experience or peer support values, and systems advocacy. Reflecting diversity in approaches, no study reported all intervention components, and no component was found among all studies.

IMPLICATIONS

Peer support services constitute a category of intervention approaches far too varied to evaluate as a single entity. Results suggest intervention components deserving more focused research, including assistance in self-management, "being there," and explicit utilization of shared lived experience or peer support values.

PRISMA/PROSPERO

As this article reports results from a realist review of the literature, we did not follow the PRISMA guidance which is suitable for systematic reviews. We did follow the Realist and Meta-narrative Evidence Syntheses: Evolving Standards (RAMESES) guidelines.This review was not registered on PROSPERO as it is not a systematic review.

Reducing self-stigma in psychosis: A systematic review and meta-analysis of psychological interventions

The burden of self-stigma in psychosis has been widely studied, leading to the development and implementation of self-stigma reduction programmes to ameliorate its impact. In order to successfully improve self-stigma in psychosis, we must evaluate the effect of available interventions to help clinicians select the most appropriate approach for their patients. This systematic review and meta-analysis aimed to evaluate the effect of self-stigma reduction interventions in people with psychosis while considering the interventions' characteristics as an important moderator of their effect. The results from this systematic review suggest that interventions involving more than one component, particularly those combining psychoeducation, social skills training and cognitive approaches, were most effective at reducing self-stigma in people with psychosis. Additionally, shorter interventions were found best reduced self-stigma at post-treatment evaluation. A meta-analysis mirrored these results, finding an overall favourable effect of interventions but high heterogeneity in the sample. Subgroup analyses found larger self-stigma reductions following multi-component interventions compared to single-component interventions. An analysis of risk of bias revealed a trend suggesting studies with lower risk of bias produced smaller effects. The results of this review can inform practitioners select and develop interventions to reduce self-stigma in psychosis.

Manualized group cognitive behavioral therapy for social anxiety in first-episode psychosis: a randomized controlled trial

BACKGROUND

Social anxiety (SA), a prevalent comorbid condition in psychotic disorders with a negative impact on functioning, requires adequate intervention relatively early. Using a randomized controlled trial, we tested the efficacy of a group cognitive-behavioral therapy intervention for SA (CBT-SA) that we developed for youth who experienced the first episode of psychosis (FEP). For our primary outcome, we hypothesized that compared to the active control of group cognitive remediation (CR), the CBT-SA group would show a reduction in SA that would be maintained at 3- and 6-month follow-ups. For secondary outcomes, it was hypothesized that the CBT-SA group would show a reduction of positive and negative symptoms and improvements in recovery and functioning.

METHOD

Ninety-six patients with an FEP and SA, recruited from five different FEP programs in the Montreal area, were randomized to 13 weekly group sessions of either CBT-SA or CR intervention.

RESULTS

Linear mixed models revealed that multiple measures of SA significantly reduced over time, but with no significant group differences. Positive and negative symptoms, as well as functioning improved over time, with negative symptoms and functioning exhibiting a greater reduction in the CBT-SA group.

CONCLUSIONS

While SA decreased over time with both interventions, a positive effect of the CBT-SA intervention on measures of negative symptoms, functioning, and self-reported recovery at follow-up suggests that our intervention had a positive effect that extended beyond symptoms specific to SA.ClinicalTrials.gov identifier: NCT02294409.

Epistemic injustice amongst clinical and non-clinical voice-hearers: A qualitative thematic analysis study

OBJECTIVES

Research has suggested people who hear voices may be at risk of epistemic injustice. This is a form of discrimination whereby someone is unfairly judged to be an unreliable knower (testimonial injustice) or is unable to contribute to, and therefore access, concepts that make sense of their experience within mainstream society (hermeneutical injustice). Voice-hearing occurs both in people who are mental health service users and in the general population (clinical and non-clinical voice-hearers, respectively). The degree of distress and impairment associated with voices has been shown to relate to how individuals make sense of their experiences and how others respond to their identity as a voice-hearer. The aim of this study was to explore people's experiences of epistemic injustice in relation to voice-hearing and to understand how these may differ between clinical and non-clinical voice-hearers.

DESIGN

A qualitative design was used.

METHOD

Eight clinical and nine non-clinical voice-hearers partook in semi-structured interviews, which were analysed using thematic analysis.

RESULTS

Three pairs of themes related to (i) identity, (ii) relationships and (iii) power and position were constructed across the clinical and non-clinical groups, and two shared themes within both groups were created relating to testimonial and hermeneutical injustice.

CONCLUSION

Both clinical and non-clinical voice-hearers described experiencing epistemic injustice in wider society. The presence of a 'safe haven' (e.g. spiritualist churches) for non-clinical voice-hearers ameliorated the impact of this to some degree, by allowing people to make connections with others with similar experiences within a non-judgemental and accepting community.

The clinical and psychosocial correlates of self-stigma among people with schizophrenia spectrum disorders across cultures: A systematic review and meta-analysis

BACKGROUND

Individuals with schizophrenia spectrum disorders (SSD) are at heightened risk of experiencing self-stigma, and some cultures are more stigmatizing towards SSD than others. The first purpose of this review is to provide an estimate of the relationship between self-stigma and clinical and psychosocial outcomes. The second purpose is to examine how these relationships vary across cultures.

METHOD

Studies reporting correlations between self-stigma and outcome variable(s) were identified through electronic database searches from June 1, 2021, to January 2, 2022. Mean effect sizes were calculated using Fisher's r-to-Z-transformation.

RESULTS

Sixty-three articles (N = 8925, 22 countries) were included in the systematic review and fifty-three articles (N = 7756) were included in the meta-analysis. For the most studied clinical correlates, self-stigma had a moderate, positive correlation with depressive symptoms (r = 0.49, p < .001), a moderate, negative correlation with functioning (r = -0.39, p < .001), and a positive, small correlation with severity of psychotic symptoms (r = 0.29, p < .001), negative symptoms (r = 0.18, p < .001) and positive symptoms (r = 0.13, p = .01). For the most studied psychosocial correlates, self-stigma had a strong, negative correlation with quality of life (r = -0.52, p < .001) and self-esteem (r = -0.55, p < .001). The correlates of self-stigma were similar across cultures.

DISCUSSION

Self-stigma shows strong to small correlations with clinical and psychosocial variables similarly across cultures. More research is needed to examine underlying mechanisms to develop effective interventions.

Social exclusion in psychotic disorders: An interactional processing model

Psychotic disorders are among the most highly stigmatized mental disorders, and individuals with psychosis experience significant exclusion from the community. Stigma reduction programs have done little to reduce social exclusion of individuals with psychosis, and there are significant limitations to the traditional stigma model as it applies to social exclusion. Herein, we present the Interactional Processing Model (IPM) of social exclusion towards individuals with psychosis. The IPM considers social exclusion to be the result of two interacting pathways with additional consideration for a feedback loop through which social exclusion sets in motion natural behavioural responses of individuals with psychosis that inadvertently perpetuates exclusion. The IPM considers initial social exclusion to be the result of an interaction between these two pathways. The first path aligns with the traditional stigma model and consists of the community becoming aware that an individual is diagnosed with a psychotic disorder and then excluding the individual based on pre-existing, generalized knowledge about the disorder. The second path to exclusion involves the observation of atypical behaviours from the individual, and generation of an individualized exclusion response. We provide initial empirical support for the IPM of social exclusion, outline testable hypotheses stemming from the model, and discuss implications for novel ways to consider both societal stigma reduction and personalized intervention.

Stigma towards individuals with schizophrenia: Examining the effects of negative symptoms and diagnosis awareness on preference for social distance

Social exclusion towards individuals with schizophrenia can occur as a result of stigmatizing attitudes towards the diagnosis or as a response to observing atypical behaviours resulting from symptoms. The present study examined social exclusion towards schizophrenia as a function of diagnosis awareness and presence of negative symptoms. 64 healthy participants watched four different videos of confederates who were either labelled / not labelled with schizophrenia and displayed / did not display negative symptoms. Participants ranked their preference for social interaction with individuals in ten different activities and were told that they would complete the activities based on their rankings. A significant interaction between label and symptoms was found as knowledge of diagnosis increased desire for social distance if symptoms were absent and decreased desire for social distance if symptoms were present. A main effect of symptom presence was also found as participants displayed greater desire to complete activities with individuals not displaying symptoms than participants displaying symptoms but there was no effect of diagnostic label. Social exclusion appears to be dependent on both presence of negative symptoms and knowledge of diagnosis. It may be useful to focus on increasing public acceptance of specific symptom presentations in public mental health campaigns.

Self-concept and Engagement in LiFe (SELF): A waitlist-controlled pilot study of a novel psychological intervention to target illness engulfment in enduring schizophrenia and related psychoses

BACKGROUND

Illness engulfment, a process whereby one's self-concept becomes defined entirely by illness, is implicated in the association between insight and depressive symptomatology in schizophrenia. We examined the feasibility and acceptability of a brief intervention called Self-concept and Engagement in LiFe (SELF) that aims to reduce engulfment and enhance personal recovery.

METHODS

Forty individuals diagnosed with schizophrenia spectrum disorders were assigned to SELF intervention or waitlist-control (treatment-as-usual). Outcome measures included the Modified Engulfment Scale and measures of depressive symptomatology, self-esteem, recovery style, quality of life, and self-stigma.

RESULTS

Retention at post-therapy was 90% (18/20 completed SELF; 18/20 remained on waitlist). Eleven waitlist participants then completed SELF (73% overall retention). Participants reported high satisfaction with the intervention, and participation was associated with reduced engulfment (ES = 0.48), more adaptive recovery style (ES = 0.37), improved self-esteem (ES = 0.35), and reduced self-stigma (ES = 0.25). The treatment group had lower engulfment (adjusted mean = 91.9) compared to waitlist (adjusted mean = 100.0) post-therapy, F (1,32) = 5.78, p = .02, partial η² = 0.15.

CONCLUSIONS

The SELF intervention is highly acceptable to participants and can reduce engulfment and improve secondary outcomes. Future research should examine the efficacy of SELF in a larger randomized controlled trial.

Patterns and perceptions of face-to-face and digital communication in the clinical high risk and early stages of psychosis

Digital communication can mitigate some of the challenges inherent in face-to-face communication; however, it is unclear whether this communication format is preferred among youth with emerging psychosis. Therefore, we examined characteristics of face-to-face and digital communication in youth at clinical high risk for psychosis (CHR; n = 19) or in the first episode of psychosis (FEP; n = 57), as well as age-matched community comparisons (n = 51). Participants completed a 25-item self-report questionnaire to assess between- and within-group differences in the frequency of, satisfaction with, and barriers to face-to-face and digital communication. Compared to controls, both clinical groups endorsed a lower frequency of face-to-face and digital interactions across a range of communication partners. Controls reported higher satisfaction and fewer challenges with both communication formats than CHR and FEP groups. No between-group differences were identified among clinical participants in characteristics of face-to-face and digital interactions. Youth at clinical high risk for, or in the first episode of, psychosis exhibited similar communication patterns and perceptions that significantly diverged from community controls. These findings highlight that reductions in the quality and quantity of social interactions extend to digital contexts, and that both communication formats are relevant clinical targets in the high risk and early stages of psychosis.
