Social anhedonia in the daily lives of people with schizophrenia: Examination of anticipated and consummatory pleasure.

Social anhedonia is a hallmark symptom of schizophrenia. Discrepancies in anticipated versus consummatory pleasure for non-social stimuli are well-documented. Thus, a similar emotional paradox may underlie social anhedonia. If so, our understanding of social anhedonia-including how to treat it in schizophrenia-could be enhanced. This project used a 5-day experience sampling method (ESM) to measure discrepancies between anticipated and consummatory pleasure for real-world social activities in people with schizophrenia and healthy controls (n = 30/group). ESM results were compared to laboratory assessments of negative symptoms and neurocognition. The schizophrenia group exhibited similar levels of anticipated and consummatory social pleasure as controls throughout daily life, and both groups were accurate in their short-term predictions of pleasure. Clinical interviews revealed those with schizophrenia showed significant deficits in long-term social pleasure prediction (i.e., a 1-week timeframe). Thus, people with schizophrenia may exhibit differences in ability to predict pleasure in the short-term versus the long-term. Negative symptoms and neurocognition were related to anticipated, but not consummatory, social pleasure, suggesting anhedonia is driven by deficits in thinking about pleasure, rather than inability to experience pleasure. Clinical implications include focusing on building upon short-term ability to predict pleasure in therapy to increase social motivation in schizophrenia.

Social Activity in Schizotypy: Measuring Frequency and Enjoyment of Social Events.

Improving social functioning deficits-a core characteristic of schizophrenia-spectrum disorders-is often listed by patients as a key recovery goal. Evidence suggests that social deficits also extend to people with schizotypy, a group at heightened risk for psychotic and other psychopathological disorders. One challenge of social functioning research in schizotypy is understanding whether social deficits arise from receiving less pleasure from social activities or from participating less in high-pleasure activities. However, limited information exists on what constitutes highly pleasurable, common social activities. In this study, 357 college students rated the frequency and enjoyment of 38 social activities. Our aims were to categorize activities based on their frequency and enjoyment, and whether these correlated with validated social functioning and schizotypy measures. We found that social activities could be characterized based on their frequency and enjoyment and created a frequency-enjoyment matrix that could be useful for future studies. Activities were correlated with social functioning, generally reaching a small effect size level, with increasing frequency and enjoyment showing associations with greater social functioning. Further, negative and disorganized-but not positive-traits were associated with less engagement and pleasure. Although follow-up studies in community samples are needed, our findings have the potential to help researchers and clinicians better understand which activities participants are more likely to engage in and derive pleasure from. The findings may also illustrate the extent to which social deficits may be due to less engagement or less pleasure from social activities, as well as which aspects of schizophrenia-spectrum disorders are associated with these facets of social functioning.

Differential Risk: Gender and Racial Differences in the Relationship between Trauma, Discrimination, and Schizotypy.

Traumatic experiences are associated with increased experiences of positive schizotypy. This may be especially important for People of Color, who experience higher rates of trauma and racial discrimination. No study to date has examined how racial disparities in traumatic experiences may impact schizotypy. Furthermore, of the studies that have examined the relationship between trauma and schizotypy, none have examined racial discrimination as a potential moderator. The present study examined if racial discrimination moderates the relationship between trauma and multidimensional (positive, negative, and disorganized) schizotypy. In a sample of 770 college students, we conducted chi-squared analyses, analyses of variance, and stepwise regressions. We found that Black students experienced significantly higher racial discrimination and trauma than Latinx and Asian students. Furthermore, Black and Latinx students experienced significantly more multidimensional schizotypy items than Asian students. Trauma and racial discrimination explained 8 to 23% of the variance in each dimension of schizotypy. Racial discrimination did not moderate the relationships between trauma and multidimensional schizotypy. Our findings suggest that we need to examine risk factors that may prevent recovery from psychotic disorders. Additionally, disorganized schizotypy showed the most robust associations and may be a critical site of intervention.

Narrative Forewarnings: A Qualitative Analysis of the Themes Preceding Disorganized Speech in Schizophrenia.

Disorganized speech is a critical barrier to recovery in schizophrenia, with profound negative impacts on one's ability to engage with the world. Despite the limited efficacy of existing treatments in addressing disorganization, a qualitative analysis of what leads to disorganization in patient narratives has been lacking. This study addresses this gap through inductive thematic analysis of 30 narrative interviews with individuals with schizophrenia, matched based on whether Formal Thought Disorder (FTD) is present. Through this analysis, we identified four core themes (alienation, interpersonal tension, personal benchmarks, and adverse experiences) and eight subthemes. Our findings suggest that disorganization may serve as a protective mechanism against psychological distress and highlight how the severity of FTD influences these themes. Alienation, particularly due to illness-related stigma, emerged more prominently in those with FTD. The themes of personal benchmarks and interpersonal tension pointed towards a heightened sensitivity to social interactions and self-perception among those with schizophrenia. Adverse experiences, encompassing past challenges, suggest a potential link between trauma and symptom exacerbation. Our qualitative analysis of what themes precede disorganized speech has implications for tailoring psychotherapy. By considering an individual's specific triggers and level of disorganization, therapy may be more effectively targeted to improve recovery-based outcomes. By identifying themes within patient narratives, this study advances our understanding of the qualitative aspects preceding disorganized speech in schizophrenia, paving the way for more personalized and effective recovery-focused interventions.

Meta-analysis of the relationship between metacognition and disorganized symptoms in psychosis.

OBJECTIVE: Disorganized symptoms show associations with metacognitive deficits in psychosis. However, the magnitude of this relationship is unclear. This meta-analysis aimed to 1) quantify relationships between metacognition and both disorganized symptoms and disorganized speech; and 2) examine moderators of these relationships (e.g., metacognition type, neurocognition). METHOD: A literature search was conducted using PsycINFO, Web of Science, PubMed, and EMBASE databases. English-language studies measuring disorganized symptoms and metacognition (i.e., introspective accuracy, metacognitive beliefs, or metacognitive capacity) in psychosis were included. Random effects meta-analyses were conducted using Pearson's r. RESULTS: Meta-analysis of 20 studies (n = 1490) resulted in a significant negative medium correlation between disorganized symptoms and metacognition (r = -0.332, 95 % CI [-0.423, -0.235]). Magnitude was moderated by metacognition type. A significant negative small correlation between disorganized speech and metacognition (r = -0.173, 95 % CI [-0.254, -0.089], n = 1470) was observed, with no significant moderators. CONCLUSIONS: Results clarify the magnitude of the relationships between metacognition and both disorganized symptoms and disorganized speech. Significant relationships may indicate conceptual links, yet the different magnitudes may reflect a distinction between disorganized symptoms and speech. The moderator finding highlights that metacognitive capacity has an especially strong link to disorganized symptoms and underscores the need for careful distinction between types of metacognition in future work.

Diversity, equity, and inclusivity in observational ambulatory assessment: Recommendations from two decades of Electronically Activated Recorder (EAR) research.

Ambient audio sampling methods such as the Electronically Activated Recorder (EAR) have become increasingly prominent in clinical and social sciences research. These methods record snippets of naturalistically assessed audio from participants' daily lives, enabling novel observational research about the daily social interactions, identities, environments, behaviors, and speech of populations of interest. In practice, these scientific opportunities are equaled by methodological challenges: researchers' own cultural backgrounds and identities can easily and unknowingly permeate the collection, coding, analysis, and interpretation of social data from daily life. Ambient audio sampling poses unique and significant challenges to cultural humility, diversity, equity, and inclusivity (DEI) in scientific research that require systematized attention. Motivated by this observation, an international consortium of 21 researchers who have used ambient audio sampling methodologies created a workgroup with the aim of improving upon existing published guidelines. We pooled formally and informally documented challenges pertaining to DEI in ambient audio sampling from our collective experience on 40+ studies (most of which used the EAR app) in clinical and healthy populations ranging from children to older adults. This article presents our resultant recommendations and argues for the incorporation of community-engaged research methods in observational ambulatory assessment designs looking forward. We provide concrete recommendations across each stage typical of an ambient audio sampling study (recruiting and enrolling participants, developing coding systems, training coders, handling multi-linguistic participants, data analysis and interpretation, and dissemination of results) as well as guiding questions that can be used to adapt these recommendations to project-specific constraints and needs.

Social pleasure in daily life: A meta-analysis of experience sampling studies in schizophrenia.

Social anhedonia is considered a key feature of schizophrenia that leads to impaired social functioning. Although traditional laboratory measures assess non-current social pleasure, researchers have begun using experience sampling methods (ESM) to measure current, or consummatory, experiences of social pleasure in daily life. A recent meta-analysis examined deficits in consummatory social pleasure in schizophrenia and found vast heterogeneity in effect sizes across ESM studies. Thus, this meta-analysis aimed to extend those results by testing moderators of this effect. Meta-analysis of 14 ESM studies suggests those with psychotic disorders exhibit a moderate deficit in consummatory social pleasure compared to healthy controls. Yet, this effect was significantly moderated by the type of measure used to assess social pleasure. Measures that directly assessed positive emotional experience during socialization yielded small effects that failed to reach significance; indirect measures of other social factors related to pleasure yielded large, significant effects. This suggests daily social anhedonia observed in psychotic disorders is not due to reduced experience of positive emotion. Instead, social anhedonia may be driven by other elements of social functioning. Most clinical variables did not influence effects, but there was a trend such that patient groups with lower cognitive functioning exhibited greater pleasure deficits. Inconsistent reporting across studies limited our ability to examine other real-world variables that may contribute to deficits in social pleasure. Yet, results show different ESM items used to measure social pleasure do not assess the same construct. Future research is needed to validate ESM measures and standardize protocols across studies.

Metacognitive Beliefs and Metacognitive Capacity: Do They Assess Related Phenomena?

ABSTRACT: Metacognition has been defined several ways across different fields. In schizophrenia, two primary approaches to assessing metacognition focus on measuring metacognitive beliefs and metacognitive capacity. The degree of association between these two approaches is unclear. In this pilot study, schizophrenia (n = 39) and control (n = 46) groups were assessed using metacognitive beliefs (Metacognition Questionnaire-30) and metacognitive capacity (Metacognition Assessment Scale-Abbreviated) scales. We also examined how these two approaches predicted quality of life. Results showed anticipated differences for metacognitive beliefs, metacognitive capacity, and quality of life when comparing schizophrenia and healthy control groups. However, metacognitive beliefs and metacognitive capacity were not significantly related and only predicted quality of life in the healthy control group. Although preliminary, these findings suggest that these two approaches have a limited relationship with one another. Future studies should test these findings in larger samples and focus on examining associations at different levels of metacognitive functioning in those with schizophrenia.

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.

Automated measures of speech content and speech organization in schizophrenia: Test-retest reliability and generalizability across demographic variables.

Technological advances in artificial intelligence and natural language processing have increased efficiency of assessing speech content and speech organization in schizophrenia. Despite these developments, there has been little focus on the psychometrics of these approaches. Using two common assessments, the current study addressed this gap by: 1) measuring test-retest reliability; and 2) assessing whether speech content and/or speech organization generalize across demographics. To test these aims, we examined psychometric properties of the Linguistic Inquiry Word Count (LIWC), a speech content measure, and the Coh-Metrix, a speech organization measure. Across baseline to six month (n = 101) and baseline to one year (n = 47) narrative speech samples, we generally observed fair reliability for speech content measures and fair to good reliability for speech organization measures. Regarding demographics, multiple speech indices varied by race, income, and education. The lack of excellent reliability scores for speech indices holds important implications for examining speech variables in clinical trials and highlights the dynamic nature of speech. This work illustrates the importance of designing speech content and speech organization measures with external validity across demographic factors. Future studies examining speech in schizophrenia should account for potential biases against demographic groups introduced by linguistic analysis tools.

Mild vs. moderate: How behavioral speech measures predict metacognitive capacity across different levels of formal thought disorder.

Disorganized speech is a key component of formal thought disorder (FTD) in schizophrenia. Recent work has tied disorganized speech to deficits in metacognition, or one's ability to integrate experiences to form complex mental representations. The level of FTD at which differences in metacognitive capacity emerge remains unclear. Across two studies, using different cut scores to form FTD groups, we aimed to 1) explore the relationship between disorganized speech and metacognition and 2) compare trained rater and automated analysis methods. Clinical interviews were coded for disorganized speech and metacognition using the Communication Disturbances Index (CDI), Coh-Metrix multidimensional indices, and Metacognition Assessment Scale. In Study 1, we examined CDI and Coh-Metrix's ability to predict metacognition in FTD (n = 16) and non-FTD (n = 29) groups. We hypothesized the FTD group would have lower metacognition and that both CDI and Coh-Metrix would account for significant variance in metacognition. In Study 2, we conducted the same analyses with an independent sample using more stringent FTD cut scores (FTD: n = 23; non-FTD: n = 23). Analyses indicated that at a moderate but not mild cutoff: 1) automated methods differentiated FTD and non-FTD groups, 2) differences in metacognition emerged, and 3) behavioral measures accounted for significant variance (34%) in metacognition. Results emphasize the importance of setting the FTD cutoff at a moderate level and using samples that contain high levels of FTD. Findings extend research linking FTD and metacognition and demonstrate the benefit of pairing trained rater and automated speech measures.

Emergence of Language Related to Self-experience and Agency in Autobiographical Narratives of Individuals With Schizophrenia.

BACKGROUND AND HYPOTHESIS: Disturbances in self-experience are a central feature of schizophrenia and its study can enhance phenomenological understanding and inform mechanisms underlying clinical symptoms. Self-experience involves the sense of self-presence, of being the subject of one's own experiences and agent of one's own actions, and of being distinct from others. Self-experience is traditionally assessed by manual rating of interviews; however, natural language processing (NLP) offers automated approach that can augment manual ratings by rapid and reliable analysis of text. STUDY DESIGN: We elicited autobiographical narratives from 167 patients with schizophrenia or schizoaffective disorder (SZ) and 90 healthy controls (HC), amounting to 490 000 words and 26 000 sentences. We used NLP techniques to examine transcripts for language related to self-experience, machine learning to validate group differences in language, and canonical correlation analysis to examine the relationship between language and symptoms. STUDY RESULTS: Topics related to self-experience and agency emerged as significantly more expressed in SZ than HC (P < 10-13) and were decoupled from similarly emerging features such as emotional tone, semantic coherence, and concepts related to burden. Further validation on hold-out data showed that a classifier trained on these features achieved patient-control discrimination with AUC = 0.80 (P < 10-5). Canonical correlation analysis revealed significant relationships between self-experience and agency language features and clinical symptoms. CONCLUSIONS: Notably, the self-experience and agency topics emerged without any explicit probing by the interviewer and can be algorithmically detected even though they involve higher-order metacognitive processes. These findings illustrate the utility of NLP methods to examine phenomenological aspects of schizophrenia.

Meaning-making processes across the lifespan: An investigation of the developmental course of metacognitive capacity.

Deficits in metacognitive capacity (i.e., the ability to integrate knowledge of oneself and others into a cohesive whole) have been shown to lead to poor functional outcome in psychosis. However, there is a gap in the literature concerning the role of metacognition in typically developing populations, which makes it difficult to define what level of metacognition is normative and at what point deficits in metacognition suggest pathology. To explore this issue, we utilized cross-sectional design to assess metacognitive capacities among 69 neurotypical adults whose ages varied from 18 to 65 using the Metacognitive Assessment Scale - Abbreviated (MAS-A) and then compared those with MAS-A scores from a second previously gathered sample of 360 adults diagnosed with psychosis across four key developmental windows: emerging adulthood, early adulthood, middle adulthood, and late adulthood. Our findings suggest that in our overall sample, individuals with psychosis had significantly lower levels of metacognitive capacity across all domains assessed by the MAS-A in comparison to neurotypical individuals. Additionally, our data suggest a deleterious effect of psychosis such that individuals with psychosis showed significantly lower metacognition in each developmental stage. Additionally, these differences were largest in emerging and late adulthood and for both groups awareness of others stood out as the single metacognitive domain which was significantly less impaired among older groups. Our results suggest a developmental course for metacognitive capacity such that awareness of others is the sole domain that grows over the lifespan.

Stuck Inside: How Social Functioning in Schizophrenia Changed During the COVID-19 Pandemic.

ABSTRACT: Social distancing policies enacted during the COVID-19 pandemic altered our social interactions. People with schizophrenia, who already exhibit social deficits, may have been disproportionally impacted. In this pilot study, we a) compared prepandemic social functioning to functioning during the pandemic in people with schizophrenia ( n = 21) who had data at both time points; and b) examined if patterns of decline in schizophrenia differed from healthy controls ( n = 21) across a series of repeated-measures analyses of variance. We observed larger declines in social functioning in schizophrenia (η 2 = 0.07, medium effect size) during the pandemic compared with the control group. Between-group declines did not extend to other domains, suggesting that declines are specific to social functioning. Our findings signal that treatments focusing on reconnecting people with schizophrenia to their social networks should be prioritized. Future studies should continue tracking social functioning after the pandemic to illustrate patterns of recovery.

Semantic and phonetic similarity of verbal fluency responses in early-stage psychosis.

Linguistic abnormalities can emerge early in the course of psychotic illness. Computational tools that quantify similarity of responses in standardized language-based tasks such as the verbal fluency test could efficiently characterize the nature and functional correlates of these disturbances. Participants with early-stage psychosis (n=20) and demographically matched controls without a psychiatric diagnosis (n=20) performed category and letter verbal fluency. Semantic similarity was measured via predicted context co-occurrence in a large text corpus using Word2Vec. Phonetic similarity was measured via edit distance using the VFClust tool. Responses were designated as clusters (related items) or switches (transitions to less related items) using similarity-based thresholds. Results revealed that participants with early-stage psychosis compared to controls had lower fluency scores, lower cluster-related semantic similarity, and fewer switches; mean cluster size and phonetic similarity did not differ by group. Lower fluency semantic similarity was correlated with greater speech disorganization (Communication Disturbances Index), although more strongly in controls, and correlated with poorer social functioning (Global Functioning: Social), primarily in the psychosis group. Findings suggest that search for semantically related words may be impaired soon after psychosis onset. Future work is warranted to investigate the impact of language disturbances on social functioning over the course of psychotic illness.

Personalizing interventions using real-world interactions: Improving symptoms and social functioning in schizophrenia with tailored metacognitive therapy.

OBJECTIVE: When clients' lives are not reflected in therapy, they struggle to apply the skills learned in treatment to everyday situations. In this pilot study, we determined if using clients' real-world interactions in therapy could effectively target metacognitive capacity-yielding improved symptoms and social functioning-by tailoring treatment to focus on issues faced by clients in daily life. METHOD: Using a randomized controlled trial design, schizophrenia subjects with metacognitive deficits completed 24 sessions of: (a) Standard Metacognitive Reflection and Insight Therapy (MERIT); or (b) Tailored MERIT. Real-world interactions were captured via the Electronically Activated Recorder (EAR), a smartphone application that passively records audio in daily life. All subjects wore the EAR; however, real-world interactions were only used to personalize sessions in Tailored MERIT. RESULTS: Feasibility and acceptability were shown; those in Tailored MERIT wore the EAR 84% of their waking hours and reported minimal burden. When compared to Standard MERIT, Tailored MERIT participants showed large pre-post reductions in negative metacognitive beliefs and disorganized symptoms. Small, but nonsignificant, improvements in social functioning were also observed. CONCLUSIONS: Compared to an evidence-based benchmark, we observed that real-world interactions can be used to tailor metacognitive therapy and improve outcomes in schizophrenia. Tailored MERIT has the potential to impact practice by personalizing treatment to account for individual variations in environment and lifestyle-aligning with the Precision Medicine Initiative-in a way that is not possible with current therapy. This is particularly salient in schizophrenia, where limited insight and cognitive deficits often make subjective reporting unreliable. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

Social functioning in schizophrenia: Comparing laboratory-based assessment with real-world measures.

Researchers have measured social functioning in schizophrenia using many different strategies. Recent technological advances have made it possible to passively measure behaviors in real-world social situations-allowing for more objective, ecologically valid assessments. Yet, research testing the convergent validity among real-world and laboratory-based social functioning assessment is sparse. The purpose of this study was to test the convergent validity among four social functioning measures: two interview-based rating scales, a self-reported ecological momentary assessment (EMA), and a passive, ambulatory ecological assessment. Data was collected from 36 people with schizophrenia and 33 control participants. Across the entire sample, relationships between interview-based ratings and real-world measures of social functioning only demonstrated small correlations (r's = 0.17-0.19), whereas real-world measures exhibited moderate correlations with one another (r = 0.36). Within groups, real-world measures showed moderate, significant relationships in the control group (r = 0.44) but not in the schizophrenia group (r = 0.27). For those with schizophrenia, the interview-based measures of social functioning were moderately associated with ambulatory ecological assessment (r's = 0.38 and 0.47), but only small associations were observed with self-reported EMA (r's = 0.15 and 0.17). Results suggest social functioning assessments are not highly convergent and likely target different aspects of social functioning. Laboratory-based measures offer global impressions of social functioning whereas real-world measures represent a more nuanced approach. Moreover, ambulatory ecological assessment may most accurately gauge frequency of daily social interactions for those with schizophrenia as it circumvents common pitfalls of self-report and offers a less-biased, in-depth evaluation of social behavior.

Quality versus quantity: Determining real-world social functioning deficits in schizophrenia.

Social dysfunction is a hallmark of schizophrenia that is associated with emotional disturbances. Researchers have employed ecological momentary assessment (EMA) to measure social and emotional functioning in people with schizophrenia. Yet, few studies have evaluated quality of real-world social interactions, and it is unclear how interactions impact emotional experiences in this population. Using novel EMA that passively collects audio data, we examined daily social behavior and emotion in schizophrenia (n = 38) and control (n = 36) groups. Contrary to hypotheses, both groups interacted with others at the same rate and exhibited similar levels of positive emotion. However, as expected, the schizophrenia group exhibited significantly less high-quality interactions and reported more negative emotion than controls. Social versus non-social context did not influence experienced emotion in either group. This is the first real-world study to passively assess quality of social interactions in schizophrenia. Although those with schizophrenia did not differ in their number of interactions, they were less likely to engage in substantive, personal conversations. Because high-quality interactions are linked with better social outcomes, this finding has important potential treatment implications. Future research should investigate quality of interactions across different types of social activities to gain a more nuanced understanding of social dysfunction in schizophrenia.

Comparing symptoms and emotion recognition in African American and White samples with schizophrenia.

Racial status has an important role in schizophrenia, with African American samples being rated lower than White participants on a range of constructs. In many studies, however, demographic factors are not accounted for. In the present study, African American (n = 106) and White participants (n = 81) were compared on symptom severity and emotion recognition scales while controlling for other demographic factors. Contrary to our hypothesis, there were no differences in symptoms between racial groups. However, White participants performed better on an emotion recognition measure than African Americans. These differences were most prominent in response to negatively-valenced stimuli. This study replicated previous findings of racial differences in emotion recognition but not symptom severity. Future research should assess the role of racial identity on symptom severity. In addition, further research is needed to assess if utilising multi-ethnic stimuli improves performance by racial minorities on emotion recognition measures.

A cognitive model of diminished expression in schizophrenia: The interface of metacognition, cognitive symptoms and language disturbances.

The resistance of negative symptoms to pharmacologic treatment has spurred interest in understanding the psychological factors that contribute to their formation and persistence. However, little is understood about the psychological processes that reinforce and sustain the negative symptoms domain of diminished expression. Prior research has shown that higher levels of diminished expression relate to deficits in metacognitive capacity. We propose a more complex model in which diminished expression occurs when impairments in metacognitive self-reflectivity, alterations in higher-order language structure, and cognitive symptoms interact and thus interfere with persons' ability to understand and express emotions in ways others can recognize. Individuals with schizophrenia-spectrum disorders (N = 201) provided personal narratives detailing their life story and reflections about their mental illness. Self-reflectivity was measured with the Metacognition Assessment Scale-Abbreviated, and situation models were extracted from participants' personal narratives via Coh-Metrix 3.0, an automated program that calculates language indices. Diminished expression and cognitive symptoms were measured with the Positive and Negative Syndrome Scale. Structural equation models (SEM) examined whether self-reflectivity mediated the impact of cognitive symptoms and situation models on diminished expression. Results of the SEM revealed that self-reflectivity partially mediated the impact of situation models on diminished expression (ß = -.073, p = .008, ±95% CI [-0.126, -0.019]). and fully mediated the influence of cognitive symptoms in diminished expression (ß = 0.099, p = .001, ±95% CI [0.038, 0.160]). In conclusion, results suggest that self-reflectivity, linguistic cohesion, and cognitive symptoms may be useful targets for intervention in efforts to treat diminished expression in psychosis.
