What gets in the way of social engagement in schizophrenia?

Life-course perspective on the causal mechanism of social functioning in schizophrenia spectrum disorder

BACKGROUND

Due to prior emphasis on clinical recovery in Schizophrenia Spectrum Disorder (SSD), improving social functioning (SF) was oftentimes neglected, with ⩽15% of patients achieving social recovery. Priorly, we and others have shown that life-course factors, including childhood adversities, play a role in the occurrence and severity of postmorbid SF impairments, highlighting the need to understand these factors for effective interventions.

AIM

This study investigates the mechanisms influencing SF in SSD and examines the causal roles of childhood trauma, premorbid adjustment, perceived stigma, self-esteem, and quality of life.

METHODS

This longitudinal study utilized data of 1,057 SSD patients, with measures at baseline, 3 and 6-year follow-up, from the Genetic Risk and Outcome of Psychosis cohort, to unravel the causal mechanism underlying SF utilizing Structural Equation Modeling. Determinants were assessed using validated retrospective and self-report questionnaires. Model development and testing involved a multistage process, encompassing relationships exploration, fit evaluation and model comparison.

RESULTS

We developed a probable causal model. Impaired premorbid adjustment emerged as a crucial factor, exerting negative influence on long-term SF, with a direct effect of β = -.252, p < .001 on SF at 3-year follow-up and β = -.056, p = .073 at 6-year follow-up. Childhood trauma exhibited a negative direct effect on SF at 3-year follow-up (β = -.087, p = .039), while demonstrating a substantial carry-over, indirect effect. Elevated perceived stigma negatively affected SF at 3-year follow-up (β = -.112, p = .008). The model explained 9.9% of SF variation at the 3-year follow-up and 54.3% at the 6-year follow-up.

CONCLUSIONS

While validation is necessary, we found a foundational basis for causal interpretation. Premorbid adjustment, childhood trauma, and perceived stigma are essential life-course factors shaping postmorbid SF in SSD. We recommend interventions covering both prevention and treatment for individuals with established symptoms-addressing childhood trauma, premorbid adjustment, and perceived stigma-to enhance long-term social outcomes and offer actionable insights for clinicians.

Lack of social interaction advantage: A domain-general cognitive alteration in schizophrenia

People with schizophrenia (PSZ) showed preserved ability to unconsciously process simple social information (e.g., face and gaze), but not in higher-order cognition (e.g., memory). It is yet unknown how PSZ process social interactions across different cognitive domains. This study systematically investigated the cognitive characteristics of PSZ during social interaction processing from bottom-up perception to top-down memory, and established correlations with schizophrenic symptoms. In two experiments, social interactions were consistently displayed by face-to-face or back-to-back dyads. Experiment 1 enrolled 30 PSZ and 30 healthy control subjects (HCS) with a breaking continuous flash suppression (b-CFS) paradigm. Experiment 2 recruited 36 PSZ and 36 HCS for two memory tasks, wherein participants restored the between-model distance (working memory task) and recalled the socially bound pairs (long-term memory task). Results indicated that HCS showed advantageous processing of socially interactive stimuli against non-interactive stimuli throughout two experiments, including faster access to visual consciousness, closer spatial distance held in working memory and higher recollection accuracy in long-term memory. However, PSZ did not show any of these advantages, with significant interaction effects for all three tasks (task one: p = .018, ηp2 = .092; task two: p = .021, ηp2 = .074; task three: p = .015, ηp2 = .082). Moreover, correlation analyses indicated that PSZ with more severe negative symptoms (r = -.344, p = .040) or higher medication dosages (r = -.334, p = .046) showed fewer advantages in memorizing socially interactive information. Therefore, social interaction is not prioritized in schizophrenia from bottom-up perception to top-down memory, and the magnitude of such a domain-general cognitive alteration is clinically relevant to symptom severity and medication.

The recovery experiences of individuals with schizophrenia in northwestern Ethiopia

Introduction

Schizophrenia recovery is perceived as a one-time symptom remission. However, it is a process that may continue throughout an individual's life. Understanding the recovery experience of a person with schizophrenia is an essential component of filling the mental health service gap and enhancing a smooth recovery process. The objective of this study was to explore the recovery experience of individuals with schizophrenia in a developing country.

Methods

To understand these experiences, we used qualitative research. Seventeen participants were purposefully selected from two hospitals in Northwestern Ethiopia. Semi-structured, in-depth interviews were conducted, and data was analyzed using Interpretive Phenomenological Analysis.

Results

Finally, four themes were generated: the first theme was the meaning of recovery. The definition of schizophrenia recovery differs from person to person based on their personal experience. For some, recovery means becoming free of symptoms, and for others, helping their family and being economically independent. The second theme was obstacles to recovery. The obstacles included limited understanding from family members, decreased social engagement, financial dependency, hopelessness, and suicidal thoughts. The third theme was support by family and employers. Participants received support from people around them. Family members mainly provided support by feeding, clothing, giving medications, and taking them to spiritual places. The fourth theme was coping strategies used to manage illness, which included medication adherence, visiting holy water sites and traditional healers, and listening to spiritual lessons.

Conclusion

Generally, participants focused on recovery from illness by emphasizing being free from symptoms to start their regular life. However, some of them were interested in pursuing education and engaging in work. The meaning given for recovery determines the kind of recovery process individuals have. Accepting that schizophrenia is a lifelong disorder, following medical treatments, finding ways to be active in their social life, and engaging in day-to-day activities are crucial components of recovery. In addition, since support from family members is vital, creating awareness creation programs for family members and the community is essential. Finally, psychosocial support and vocational training are important strategies that need to be considered to support recovery.

Deciding to Be Left Alone After Being Left Out: Behavioral Responses to Social Exclusion in Schizophrenia

BACKGROUND AND HYPOTHESES

People with schizophrenia are at risk for social exclusion, yet we know little about their responses. We hypothesized (1) people with schizophrenia would be more likely to withdraw following social exclusion compared to controls; (2) withdrawal intentions would be greater following exclusion compared to disappointment; (3) withdrawal behavior would be predicted by rejection sensitivity, alternative sources of acceptance, chronicity of exclusion, and perceived fairness; and (4) withdrawal following exclusion would be associated with more negative symptoms and poorer functioning.

STUDY DESIGN

People with (n = 43) and without (n = 43) schizophrenia or schizoaffective disorder played Cyberball - Behavioral Response, a novel version of the exclusion task. Participants responded to social exclusion with affiliative, retaliatory, and withdrawal behaviors within a 2 (Group: Schizophrenia vs. Control) × 3 (Game Type: Exclusion vs. Disappointment vs. Inclusion) mixed design. Participants reported their social experiences, affective and psychological responses following exclusion, negative symptoms, and functioning.

STUDY RESULTS

People with schizophrenia reported heightened rejection sensitivity, fewer alternative sources of acceptance, and more chronic exclusion in daily life compared to controls. They responded to exclusion with more withdrawal behavior than controls, with social exclusion eliciting more of these responses than disappointment. Withdrawal responses were associated with chronicity of exclusion, and withdrawal and exclusion in daily life were linked to functional outcomes.

CONCLUSIONS

People with schizophrenia experience frequent social exclusion in daily life, and this predicts withdrawal responses to social exclusion. Findings provide initial evidence of vulnerability to a cycle of exclusion and withdrawal.

Validation of the Comprehensive and Brief International Classification of Functioning, Disability and Health Core Sets for Schizophrenia from the Perspective of Individuals Diagnosed with the Disorder: A Worldwide Study Using Focus Groups

The comprehensive and brief International Classification of Functioning, Disability and Health (ICF) core sets for schizophrenia, based on the World Health Organization (WHO) framework, aim to describe the functioning of individuals with schizophrenia. The objective of this study was to identify the most common problems faced by these individuals and validate the ICF core sets. Eight focus groups were conducted, recorded, and transcribed verbatim. The linking process involved two independent coders identifying meaningful units and linking agreed-upon concepts to the ICF categories. Data saturation was defined as the point at which no new categories emerged from additional focus groups. The 37 participants in this study represented the WHO regions of Africa, South-East Asia, the Western Pacific, and Europe. The focus groups confirmed the relevance of all ICF core set categories, with an additional 21 second-level categories being proposed in at least six of the eight focus groups. In this study, the ICF core sets for schizophrenia were validated from the perspective of individuals. However, several second-level categories not currently included in the ICF core sets also emerged. To ensure that the ICF core sets are truly international in scope, the potential relevance of these categories should be investigated further.

'To loosen up and talk': Patients´ and facilitators´ experiences of discovery group sessions from the Tidal Model as an introduction before engaging in a person-centred group intervention

WHAT IS KNOWN ABOUT THE SUBJECT

Treatment groups in Mental Health Service is cost-effective, increases patients´ self-understanding and stimulate change Research shows that people with mental illness have different barriers to attend group sessions which often originates from a lack of trust in other people, but it is known that the possibility to build gradual trust among the participants encourages attendance.

WHAT THE PAPER ADDS TO EXISTING KNOWLEDGE

This study is based on the experience from outpatients and illuminates how discovery groups from the Tidal Model can be used as introductory sessions to build gradual trust among people with mental illness before engaging in a person-centred group intervention. The study fills a research gap in methods to create a safe and trusting environment in treatment groups for people with mental illness working with recovery-oriented person-centred interventions.

WHAT ARE THE IMPLICATIONS FOR PRACTICE

This study emphasizes the importance of meeting concerns about social interactions in persons with mental illness when joining treatment groups. It presents a recovery-oriented method which meets this requirement and is easy to implement in practice.

ABSTRACT

INTRODUCTION: Recovery-oriented interventions delivered individually or in groups are more and more common within mental health nursing. However, persons with mental illness may be cautious about engaging in groups. Therefore, it is important to provide a trusting basis in the group to allow for the best opportunities to promote engagement, attendance and impact of treatment.

AIM

The aim was to explore how discovery group sessions were experienced as introductory sessions from the perspectives of participants and facilitators before engaging in a person-centred group intervention.

METHOD

A qualitative interview study was conducted, involving four group facilitators and 16 participants with mental illness from five completed groups. Data were analysed with Ricoeur's theory of interpretation.

RESULTS

The findings showed that the two discovery group sessions were experienced as useful and meaningful to all and created a safe atmosphere and a trusted relationship among group participants and facilitators.

DISCUSSION

Feeling safe and sharing experiences and emotions contribute to the relational climate in a group.

IMPLICATION FOR PRACTICE

Addressing concerns about social interactions in persons with mental illness is important in group treatment. This study proved that engaging patients in designing or adapting interventions for mental health services is important to improve quality.

Relationship between the Use of Mobile Applications and Social Functioning in Patients with Schizophrenia

OBJECTIVES

The aim of this study is to examine the prevalence of digital technology tool use in individuals with schizophrenia or schizoaffective disorder in Turkey, as well as evaluating the association between the use and psychosocial functionality and clinical symptoms.

METHOD

Data were collected from 100 patients who were diagnosed with schizophrenia or schizoaffective disorder based on the DSM-5 criteria. The use of technology was evaluated with a questionnaire developed for this study. The level of psychosocial functioning was assessed using the Personal and Social Performance Scale (PSP), and the positive and negative symptom severity was evaluated using the Positive and Negative Syndrome Scale (PANSS).

RESULTS

The digital technology users were significantly younger than the non-users. The majority of patients own a mobile phone (86%) and a computer (67%). Furthermore, 61% of patients used mobile applications, with Facebook and WhatsApp being the most popular social media platforms (48%). Patients who used digital technology tools had higher PSP scores. Furthermore, patients who used digital technology tools had significantly lower scores in PANSS negative subscale. There was no difference in PANSS positive subscale scores between digital technology tool users and non-users.

CONCLUSION

Patients diagnosed with schizophrenia may benefit from mobile applications and social media tools that can help them participate in daily activities and improve their overall well-being.

Neurostructural changes in schizophrenia and treatment-resistance: a narrative review

Schizophrenia is a complex disorder characterized by multiple neurochemical abnormalities and structural changes in the brain. These abnormalities may begin before recognizable clinical symptoms appear and continue as a dynamic process throughout the illness. Recent advances in imaging techniques have significantly enriched our comprehension of these structural alterations, particularly focusing on gray and white matter irregularities and prefrontal, temporal, and cingulate cortex alterations. Some of the changes suggest treatment resistance to antipsychotic medications, while treatment nonadherence and relapses may further exacerbate structural abnormalities. This narrative review aims to discuss the literature about alterations and deficits within the brain, which could improve the understanding of schizophrenia and how to interpret neurostructural changes.

Associations between social engagement, internalizing symptoms, and delusional ideation in the general population

BACKGROUND

Delusions are a hallmark feature of psychotic disorders and lead to significant clinical and functional impairment. Internalizing symptoms-such as symptoms of depression, anxiety, and trauma exposure-are commonly cited to be related to delusions and delusional ideation and are often associated with deficits in social functioning. While emerging studies are investigating the impact of low social engagement on psychotic-like experiences, little work has examined the relationship between social engagement, internalizing symptoms, and delusional ideation, specifically.

METHODS

Using general population data from the Nathan Kline Institute-Rockland (NKI-Rockland) database (N = 526), we examined the relationships between self-reported delusional ideation, internalizing symptoms, and social engagement and tested four indirect effect models to understand how these factors interrelate.

RESULTS

Delusional ideation was significantly associated with both increased internalizing symptoms (r = 0.41, p < 0.001) and lower social engagement (r = - 0.14, p = 0.001). Within aspects of social engagement, perceived emotional support showed the strongest relationship with delusional ideation (r = - 0.17, p < 0.001). Lower social engagement was also significantly associated with increased internalizing symptoms (r = - 0.29, p < 0.001). Cross-sectional models suggest that internalizing symptoms have a significant indirect effect on the association between delusional ideation and social engagement.

CONCLUSIONS

These findings reveal that elevated delusional ideation in the general population is associated with lower social engagement. Elevated internalizing symptoms appear to play a critical role in reducing engagement, possibly exacerbating delusional thinking. Future work should examine the causal and temporal relationships between these factors.

Schizophrenia: Communication Disorders and Role of the Speech-Language Pathologist

PURPOSE

This clinical focus article aims to provide a comprehensive overview of schizophrenia and understanding of communication disorders resulting from its psychopathology. Schizophrenia is a spectrum disorder with varying levels of symptom expression. It is characterized by positive and negative symptoms that can cause communication disorders of different severity levels. Communication difficulties manifest as a range of symptoms such as alogia, disorganized speech, and impaired social communication. These challenges may result in receptive and expressive language deficits that lead to misunderstandings, reduced social interactions, and difficulties expressing thoughts and emotions effectively. The purpose of this clinical focus article is to explore the role of the speech-language pathologist (SLP) in assessing and treating communication disorders presented in schizophrenia.

CONCLUSIONS

In order to understand the role of the SLP in assessing and treating communication disorders in schizophrenia, it is imperative to understand the overall course, etiology, assessment, and treatment consideration of this condition. SLPs can provide services in the areas of social skills training and community-based intervention contexts.

Clinical and Sociodemographic Correlations with Neurological Soft Signs in Hospitalized Patients with Schizophrenia: A Preliminary Longitudinal Study

Schizophrenia is a severe, chronic neuropsychiatric disorder characterized by symptoms that profoundly impact behavior, cognition, perception, and emotions, leading to a reduced quality of life and physical impairment. Given the complexity of schizophrenia, there is a pressing need for clinical markers and tools to predict its course, enhance disease staging, facilitate early intervention, improve differential diagnosis, and tailor individualized treatment approaches. Previous studies focused on the relationship between neurological soft signs (NSS) and factors such as age, illness duration, and symptomatology, indicating NSS as state markers improving in parallel with psychotic symptom remission or predicting treatment resistance. However, there is a lack of consensus on NSS assessment tools, hindering routine clinical monitoring despite diagnostic and prognostic potential. The present longitudinal study involved 81 psychiatric inpatients diagnosed with schizophrenia. Patients were assessed at three time points: baseline, 1 month, and 6 months. The examination included the use of scales to evaluate psychotic and neurological symptoms, as well as the identification of adverse extrapyramidal reactions caused by neuroleptic treatment. The progression of NSS was correlated to both the symptomatology and the sociodemographic data of the patients. The main findings from the present investigation revealed a statistical correlation between NSS and psychopathological symptoms, especially with negative symptoms of schizophrenia. However, it is important to note that neuroleptic side effects only had a limited impact on NSS. Therefore, instead of being linked to extrapyramidal symptoms caused by neuroleptics, NSS appears to be more frequently related with symptoms of schizophrenia. Our findings provide further support for their strong association with the course of schizophrenia, independent of treatment side effects, thus emphasizing their potential as reliable assessment tools in both research and clinical settings.

Effects of metacognitive training (MCT) on social cognition for schizophrenia spectrum and related psychotic disorders: a systematic review and meta-analysis

BACKGROUND

Individuals with schizophrenia spectrum and related psychotic disorders (SSD) experience significant impairments in social cognition that impede functioning. Social cognition is a multidimensional construct consisting of four domains: 1. theory of mind, 2. emotion processing, 3. attributional style and 4. social perception. Metacognitive training (MCT) is an intervention designed to target cognitive biases in psychosis containing two modules addressing social cognition.

METHODS

A systematic review and meta-analysis was conducted to investigate the effects of MCT on social cognition and two of its domains: theory of mind and emotion processing. Ten electronic databases were scoured from 2007 to 1 February 2022 for MCT studies reporting social cognition outcomes for people with SSD (1050 identified, 282 assessed). Effect sizes were calculated using Cohen's d in R.

RESULTS

Nine studies were included in the meta-analysis (nMCT = 212, ncontrol = 194). MCT had a small but positive effect on global social cognition (d = 0.28 [95% CI 0.07-0.49]) and theory of mind (d = 0.27 [95% CI 0.01-0.52]). MCT showed no evidence of an effect on emotion processing (d = 0.03 [95% CI -0.26 to 0.32]).

CONCLUSION

MCT has a small but significant effect on social cognition for people with SSD. Our results add to other recent meta-analyses showing significant effects of MCT on clinically relevant outcomes such as positive symptoms, cognitive biases and cognitive insight. We recommend that future studies on MCT report outcomes on all four domains of social cognition.

Cognitive Control in Schizophrenia: Advances in Computational Approaches

Psychiatric research is undergoing significant advances in an emerging subspeciality of computational psychiatry, building upon cognitive neuroscience research by expanding to neurocomputational modeling. Here, we illustrate some research trends in this domain using work on proactive cognitive control deficits in schizophrenia as an example. We provide a selective review of formal modeling approaches to understanding cognitive control deficits in psychopathology, focusing primarily on biologically plausible connectionist-level models as well as mathematical models that generate parameter estimates of putatively dissociable psychological or neural processes. We illustrate some of the advantages of these models in terms of understanding both cognitive control deficits in schizophrenia and the potential roles of effort and motivation. Further, we highlight critical future directions for this work, including a focus on establishing psychometric properties, additional work modeling psychotic symptoms and their interaction with cognitive control, and the need to expand both behavioral and neural modeling to samples that include individuals with different mental health conditions, allowing for the examination of dissociable neural or psychological substrates for seemingly similar cognitive impairments across disorders.

Social Motivation in Schizophrenia: What's Effort Got to Do With It?

BACKGROUND AND HYPOTHESIS

Social motivation, defined as the fundamental human desire to seek out, engage in, and maintain interpersonal bonds, has become a growing area of research in schizophrenia. The major focus has been on understanding the impact of social reward-related processes. An obvious but rarely acknowledged fact is that social interactions, much like other goal-directed acts, require the exertion of effort. In this Review Article, we argue that social motivation in schizophrenia can be conceptualized through the lens of an established framework: effort-based decision-making (EBDM).

STUDY DESIGN

We conducted a literature review on social reward processing in schizophrenia, then extended these findings by applying concepts and insights from the literature on EBDM to the study of social motivation.

STUDY RESULTS

Within the EBDM framework, decisions about whether or not to pursue social interactions are bound by cost/benefit calculations. That is, people do not pursue social behaviors when the estimated "cost" of the required effort outweighs the anticipated "benefit" or reward. We propose that people with schizophrenia are less likely to engage in social interaction compared with healthy samples because they: (1) underestimate the benefits of relationships (based on expectations of reward/punishment), (2) overestimate the effort costs associated with social interaction, and/or (3) fail to integrate cost-benefit information in an optimal manner.

CONCLUSIONS

EBDM is an especially promising framework of social motivation that goes beyond the current focus on social reward processing to include a focus on effort.

Do People With Schizophrenia Enjoy Social Activities as Much as Everyone Else? A Meta-analysis of Consummatory Social Pleasure

BACKGROUND

The "emotion paradox" of schizophrenia suggests people with schizophrenia demonstrate deficits when reporting anticipated and retrospective pleasure; yet, in-the-moment, consummatory pleasure is largely intact. It is uncertain how these findings extend to social situations. This meta-analysis aimed to (1) determine the mean difference in consummatory social pleasure between people with schizophrenia and healthy controls, and (2) examine moderators of this effect, including study design and clinical characteristics of participants.

DESIGN

A literature search using PsycINFO, Web of Science, Pubmed, and EMBASE databases was conducted. Studies measuring consummatory social pleasure using experience sampling methods and laboratory social simulations were included. Random effects meta-analyses were conducted using Hedge's g.

RESULTS

Meta-analysis of 26 studies suggests people with schizophrenia exhibited a small, significant deficit in consummatory social pleasure (g = -0.38, 90% CI [-0.53, -0.22]). There was significant heterogeneity in effect sizes; magnitude was moderated by study design and type of measure used to assess social pleasure.

CONCLUSIONS

Overall, people with schizophrenia seem to exhibit less consummatory social pleasure than controls. However, this deficit is smaller than in studies of anticipated and retrospective pleasure. Thus, consummatory social pleasure may not be quite as impaired in people with schizophrenia as traditional anhedonia research suggests. Moreover, pleasure deficits observed in people with schizophrenia may result from differences in the quality of their daily social experiences rather than differences in their capacity for social pleasure. Results have important implications for clinical interventions that address barriers to social engagement, low-pleasure beliefs, and cognitive remediation to treat schizophrenia.

The effects of group-based cognitive behavioral therapy in the rehabilitation of patients with chronic schizophrenia with more than two years of community-based mental health group rehabilitation

BACKGROUND

Studies have shown that community-based group rehabilitation activities can have a positive impact on patients.

OBJECTIVE

This study attempted to improve schizophrenia patients' social and self-cognition through short-term group-based cognitive behavioral therapy (G-CBT), break negative coping styles, and improve the patients' quality of life.

METHODS

The patients with schizophrenia who participated in long-term community-based group rehabilitation were treated with G-CBT. Training on coping styles was conducted to improve their self-cognition and social cognition, and the rehabilitation effects of G-CBT on these patients were evaluated.

RESULTS

Compared with the control group, patient scores for self-esteem, self-efficacy, and positive coping in the G-CBT group increased, while patient scores for negative coping decreased. Compared with the control group, the differences in the total scores for mental health and the five dimensions of physical functioning, general health, vitality, social functioning, and emotional role function in the short-form (SF-12) survey were statistically significant. Compared with the baseline data, the differences in self-esteem, self-efficacy, positive coping, negative coping, and quality of life scores were statistically significant.

CONCLUSION

Short-term G-CBT had a good effect on patients with chronic schizophrenia who participated in community-based group rehabilitation for the long-term.

"Why I stay in community psychiatric rehabilitation": a semi-structured survey in persons with schizophrenia

AIMS

Although community psychiatric rehabilitation plays an important role in returning persons with schizophrenia to the society, many patients in China stay in rehabilitation centers for longer periods of time and subsequently fail to integrate. This study is aimed to explore the underlying causes of this trend and identify possible solutions.

METHODS

This study used a qualitative descriptive design to examine the persons with schizophrenia who stay in rehabilitation centers for longer periods of time. The researchers conducted semi-structured telephone interviews with the patients recruited through purposeful sampling. The audio-recorded interviews were transcribed in transcripts in Chinese. Thematic analysis was performed using Colaizzi's 7-step method.

RESULTS

Most patients believe that they have gained knowledge, improved skills, friendship and social circles through community mental rehabilitation, with the sense of belonging and enriched life strongly attracting them to the rehabilitation centers. They felt that the difficulty of further integration into society is mainly because of social prejudice and rejection. In addition, the activities of community mental rehabilitation meet the needs of social communication, which also hinder patients from further entering the society.

CONCLUSIONS

Persons with schizophrenia with long-term stay in community mental rehabilitation centers meet their friendship, sense of belonging and social needs by participating in rehabilitation activities. Providing special social opportunity for these patients can get them out of the rehabilitation center. Overall, it is possible for patients to gradually return to society in a collective form.

Intact differentiation of responses to socially-relevant emotional stimuli across psychotic disorders: An event-related potential (ERP) study

Event-related potential (ERP) studies of motivated attention in schizophrenia typically show intact sensitivity to affective vs. non-affective images depicting diverse types of content. However, it is not known whether this ERP pattern: 1) extends to images that solely depict social content, (2) applies across a broad sample with diverse psychotic disorders, and (3) relates to self-reported trait social anhedonia. We examined late positive potential (LPP) amplitudes to images involving people that were normatively pleasant (affiliative), unpleasant (threatening), or neutral in 97 stable outpatients with various psychotic disorders and 38 healthy controls. Both groups showed enhanced LPP to pleasant and unpleasant vs. neutral images to a similar degree, despite lower overall LPP in patients. Within the patients, there were no significant LPP differences among subgroups (schizophrenia vs. other psychotic disorders; affective vs. non-affective psychosis) for the valence effect (pleasant/unpleasant vs. neutral). Higher social anhedonia showed a small, significant relation to lower LPP to pleasant images across all groups. These findings suggest intact motivated attention to social images extends across psychotic disorder subgroups. Dimensional transdiagnostic analyses revealed a modest association between self-reported trait social anhedonia and an LPP index of neural sensitivity to pleasant affiliative images.

Psychological Dimensions Relevant to Motivation and Pleasure in Schizophrenia

Motivation and pleasure deficits are common in schizophrenia, strongly linked with poorer functioning, and may reflect underlying alterations in brain functions governing reward processing and goal pursuit. While there is extensive research examining cognitive and reward mechanisms related to these deficits in schizophrenia, less attention has been paid to psychological characteristics that contribute to resilience against, or risk for, motivation and pleasure impairment. For example, psychological tendencies involving positive future expectancies (e.g., optimism) and effective affect management (e.g., reappraisal, mindfulness) are associated with aspects of reward anticipation and evaluation that optimally guide goal-directed behavior. Conversely, maladaptive thinking patterns (e.g., defeatist performance beliefs, asocial beliefs) and tendencies that amplify negative cognitions (e.g., rumination), may divert cognitive resources away from goal pursuit or reduce willingness to exert effort. Additionally, aspects of sociality, including the propensity to experience social connection as positive reinforcement may be particularly relevant for pursuing social goals. In the current review, we discuss the roles of several psychological characteristics with respect to motivation and pleasure in schizophrenia. We argue that individual variation in these psychological dimensions is relevant to the study of motivation and reward processing in schizophrenia, including interactions between these psychological dimensions and more well-characterized cognitive and reward processing contributors to motivation. We close by emphasizing the value of considering a broad set of modulating factors when studying motivation and pleasure functions in schizophrenia.

An Effortful Approach to Social Affiliation in Schizophrenia: Preliminary Evidence of Increased Theta and Alpha Connectivity during a Live Social Interaction

People with schizophrenia often experience a profound lack of motivation for social affiliation—a facet of negative symptoms that detrimentally impairs functioning. However, the mechanisms underlying social affiliative deficits remain poorly understood, particularly under realistic social contexts. Here, we investigated subjective reports and electroencephalography (EEG) functional connectivity in schizophrenia during a live social interaction. Individuals with schizophrenia (n = 16) and healthy controls (n = 29) completed a face-to-face interaction with a confederate while having EEG recorded. Participants were randomly assigned to either a Closeness condition designed to elicit feelings of closeness through self-disclosure or a Small-Talk condition with minimal disclosure. Compared to controls, patients reported lower positive emotional experiences and feelings of closeness across conditions, but they showed comparably greater subjective affiliative responses for the Closeness (vs. Small-Talk) condition. Additionally, patients in the Closeness (vs. Small-Talk) condition displayed a global increase in connectivity in theta and alpha frequency bands that was not observed for controls. Importantly, greater theta and alpha connectivity was associated with greater subjective affiliative responding, greater negative symptoms, and lower disorganized symptoms in patients. Collectively, findings indicate that patients, because of pronounced negative symptoms, utilized a less efficient, top-down mediated strategy to process social affiliation.

Effects of Renaming Schizophrenia on Destigmatization among Medical Students in One Taiwan University

The stigma associated with serious mental illnesses causes a huge burden on patients, their families, and society. In October 2012, in Taiwan, schizophrenia was renamed to reduce the stigma associated with this disease. The aim of this study was to compare the differences of public stigma, self-stigma, and social distance associated with schizophrenia between old and new name of schizophrenia in medical students. A cross-sectional survey was administered to 180 medical students of Taipei Medical University from October 2014 to February 2015. In total, 123 complete questionnaires were included in this study. Participants completed the modified attribution questionnaire, the perceived psychiatric stigma scale, and modified social distance scale to assess public stigma, self-stigma, and social distance, respectively. We also collected basic demographic data and previous experience of contact with people with mental illness. In total, 52 and 71 of the first- and fourth-year medical students, respectively, participated in the study. Among them, there were 51 females and 72 males. A significant difference in age was observed between the first- and fourth-year groups (20.2 ± 1.7 years vs. 22.7 ± 0.9 years, p < 0.001). After renaming schizophrenia, we noted significant differences in the scores in the modified attribution questionnaire, the perceived psychiatric stigma scale, and the modified social distance scale in all participants and the fourth-year students, respectively. Female gender (Beta = 0.230, p = 0.018) was significantly associated with the difference in the score of the modified attribution questionnaire after name change. The difference in the score of the perceived psychiatric stigma scale after the name change (Beta = 0.277, p = 0.004) and age (Beta = −0.186, p = 0.049) were significantly associated with the difference in the score of the modified social distance scale after name change. In conclusion, renaming was associated with the changes in the scores of the modified attribution questionnaire, the perceived psychiatric stigma scale, and the modified social distance scale toward individuals with schizophrenia in medical students of one Taiwan university. Further studies with large sample sizes, diverse participant backgrounds, and that monitor the subsequent behavioral changes are warranted.
