Item A pilot randomized controlled trial comparing a novel compassion and metacognition approach for schizotypal personality disorder with a combination of cognitive therapy and psychopharmacological treatment(BMC, 2023-02-20) Cheli, Simone; Cavalletti, Veronica; Lysaker, Paul H.; Dimaggio, Giancarlo; Petrocchi, Nicola; Chiarello, Francesca; Enzo, Consuelo; Velicogna, Francesco; Mancini, Francesco; Goldzweig, Gil; Psychiatry, School of MedicineBackground: Schizotypal personality disorder is characterized by a pervasive pattern of maladaptive behavior that has been associated with the liability for schizophrenia. Little is known about effective psychosocial interventions. This pilot non-inferiority randomized controlled trial aimed to compare a novel form of psychotherapy tailored for this disorder and a combination of cognitive therapy and psychopharmacological treatment. The former treatment - namely, Evolutionary Systems Therapy for Schizotypy-integrated evolutionary, metacognitively oriented, and compassion focused approaches. Methods: Thirty-three participants were assessed for eligibility, twenty-four randomized on a 1:1 ratio, nineteen included in the final analysis. The treatments lasted 6 months (24 sessions). The primary outcome was change across nine measurements in personality pathology, the secondary outcomes were remission from diagnosis and pre-post changes in general symptomatology and metacognition. Results: Primary outcome suggested a non-inferiority of the experimental treatment in respect to control condition. Secondary outcomes reported mixed results. There was no significant difference in terms of remission, but experimental treatment showed a larger reduction of general symptomatology (η2 = 0.558) and a larger increase in metacognition (η2 = 0.734). Conclusions: This pilot study reported promising results about the effectiveness of the proposed novel approach. A confirmatory trial on large sample size is needed to provide evidence about relative effectiveness of the two treatment conditions.Item A pilot study of participatory video in early psychosis: Qualitative findings(PAGEPress, 2022-10-04) MacDougall, Arlene G.; Price, Elizabeth; Glen, Sarah; Wiener, Joshua C.; Kukan, Sahana; Powe, Laura; Bird, Richelle; Lysaker, Paul H.; Anderson, Kelly K.; Norman, Ross M. G.; Psychiatry, School of MedicineFor people with psychotic disorders, developing a personal narrative about one’s experiences with psychosis can help promote recovery. This pilot study examined participants’ reactions to and experiences of participatory video as an intervention to help facilitate recovery-oriented narrative development in early psychosis. Outpatients of an early psychosis intervention program were recruited to participate in workshops producing short documentary-style videos of their collective and individual experiences. Six male participants completed the program and took part in a focus group upon completion and in an individual semistructured interview three months later. Themes were identified from the focus group and interviews and then summarized for descriptive purposes. Prominent themes included impacts of the videos on the participants and perceived impacts on others, fulfilment from sharing experiences and expressing oneself, value of collaboration and cohesion in a group, acquiring interpersonal and technological skills, and recommendations for future implementation. Findings of this study suggest that participatory video is an engaging means of self-definition and self-expression among young people in recovery from early psychosis.Item A qualitative exploration of stakeholders' perspectives on the experiences, challenges, and needs of persons with serious mental illness as they consider finding a partner or becoming parent(Frontiers Media, 2023-01-11) Dubreucq, Marine; Lysaker, Paul H.; Dubreucq, Julien; Psychiatry, School of MedicineBackground: While many persons with serious mental illness (SMI) consider intimate relationships and becoming parent as central parts of their lives deeply affecting wellbeing and recovery, others anticipate facing multiple challenges in these life domains. This qualitative study sought to explore the perspectives of persons with SMI and mental health providers (MHPs) with diverse backgrounds and practices on the experiences, challenges, needs and expectations of persons with SMI as they consider finding a partner or becoming parent. Methods: For this qualitative study, we conducted five focus groups between March and December 2020 for a total number of 22 participants (nine persons with SMI and thirteen MHPs) recruited from a center for psychiatric rehabilitation and a community mental health center in France. We used the inductive six-step process by Braun and Clarke for the thematic analysis. Results: Participants reported some challenges related to intimate relationships, stigma/self-stigma, disclosure and decision-making about start a family. Their expectations included: (i) psychoeducation about decision-making about finding a partner and starting a family; (ii) support in making empowered decisions about finding a partner, starting a family or disclosure to a prospective partner or their child; (iii) peer-support interventions; (iv) enhancing coping strategies; (v) integrated service provision including home treatment interventions, training to recovery-oriented practices and access to dedicated resources for providers. Conclusion: In short, intimate relationships and desire to start a family for persons with SMI should be more considered in psychiatric rehabilitation and additional support and interventions should therefore be provided.Item Affective Empathy in Schizophrenia: A Meta-Analysis(Elsevier, 2016-08) Bonfils, Kelsey A.; Lysaker, Paul H.; Minor, Kyle S.; Salyers, Michelle P.; Department of Psychiatry, IU School of MedicineBackground Affective empathy, or the emotional response one has to the experiences or emotional states of others, contributes to relationship-maintaining behaviors and is key in fostering social connections, yet no work has synthesized the body of literature for people with schizophrenia. The aim of the present meta-analysis was to determine the extent to which those diagnosed with schizophrenia experience deficits in affective empathy. Methods A literature search was conducted of studies examining empathy. Data were analyzed using a random effects meta-analytic model with Hedges' g standardized mean difference effect size. Results Individuals with schizophrenia exhibited significant, medium deficits in affective empathy (k = 37). Measurement type moderated the affective empathy deficit such that performance-based measures showed larger schizophrenia group deficits than self-report measures. Conclusion Consistent, significant deficits in affective empathy were found comparing people with schizophrenia to healthy controls, especially when using performance-based assessments. The medium effect suggests an important role for empathy in the realm of social cognitive research, and points to the need for further investigation of measurement techniques and associations with functional outcomes.Item Autism Rating Scale: A New Tool for Characterizing the Schizophrenia Phenotype(Frontiers Media, 2021-01-26) Palumbo, Davide; Stanghellini, Giovanni; Mucci, Armida; Ballerini, Massimo; Giordano, Giulia Maria; Lysaker, Paul H.; Galderisi, Silvana; Psychiatry, School of MedicineSocial dysfunctions (SD) are frequently observed in subjects with schizophrenia. Some of these dysfunctions are also observed in other neuropsychiatric disorders such as autism spectrum disorders (ASD), major depression, bipolar disorder, or Alzheimer disease. Recently, a characterization of a specific type of SD in schizophrenia has been proposed, with the concept of dis-sociality, which form the core aspect of “Schizophrenic Autism” (SA). The present study aimed to explore the presence in people with schizophrenia of SA, independent of other autistic traits, which can be often found in schizophrenia and other neurodevelopmental disorders. We used a structured interview—the Autism Rating Scale (ARS), an instrument devised to detect and measure SA. Fifty-one outpatients affected by schizophrenia (26 remitted, SCZ-r) and 28 affected by bipolar disorder type 1, with psychotic features, in the euthymic phase (BD-e) were recruited. Before assessing the specificity for schizophrenia of SA, we tested the internal consistency, the convergent and divergent validity of the ARS in the schizophrenia sample. Specificity was assessed by examining potential differences in ARS scores between SCZ-r and BD-e subjects. ARS showed good internal consistency, as well as convergent and divergent validity. ARS items were more frequently of moderate severity in SCZ-r than in BD-e subjects. This scale can contribute to establish more precise phenomenal boundaries between schizophrenia and bipolar disorder, and opens up the possibility of identifying a different type of SD in schizophrenia, independent of autistic traits and negative symptoms, which might benefit from different treatments.Item Autobiographical memory in schizophrenia: The role of metacognition(Elsevier, 2021) Mediavilla, Roberto; López-Arroyo, Manuel; Gómez-Arnau, Jorge; Wiesepape, Courtney; Lysaker, Paul H.; Lahera, Guillermo; Psychiatry, School of MedicineBackground: Autobiographical memory is an important component of declarative memory, which refers to the ability to recall personal events that happened in the past. This requires that the person senses or experiences himself/herself in the past (i.e., conscious recollection). For people with schizophrenia, conscious recollection can be particularly difficult, resulting in difficulty accessing detailed, specific autobiographical information. Our hypothesis is that the ability to monitor and think about one's cognitive processes (metacognition) is a requisite for conscious recollection, and that it mediates the association between having schizophrenia and recalling fewer specific, personal memories. Methods: Participants were 30 adults with schizophrenia and 30 matched healthy controls. The main assessment instruments were the Metacognition Assessment Scale-Abbreviated (MAS-A) and the Autobiographical Memory Test (AMT). Severity of symptoms was assessed using the Positive and Negative Syndrome Scale (PANSS) for schizophrenia. Cognitive performance was measured with the Screen for Cognitive Impairment in Psychiatry (SCIP). Mediation analysis was conducted following Baron and Kenny's procedure. Results: People with schizophrenia had more semantic associations and fewer specific memories than controls in the AMT. Metacognition (MAS-A total score) partially mediated the association between having schizophrenia and recalling fewer specific past events, even after controlling for cognitive impairment as a potential confounding source. Conclusions: Metacognitive ability, which can be improved with available programs, intervenes in the process of accessing autobiographical memories in people with schizophrenia. Practical implications of this finding are discussed.Item Basic symptoms of schizophrenia are related to symptoms of traumatic stress: A pivotal role of sensitization. An observational study(Wolters Kluwer, 2022-07-15) Pec, Ondrej; Lysaker, Paul H.; Bob, Petr; Psychiatry, School of MedicineIntroduction: Subjective cognitive deficits have been broadly reported in schizophrenia and described by Huber as basic symptoms. It remains unclear however to what extent they may be related to psychosocial stressors including trauma. Methods: We assessed basic symptoms using the Frankfurt Complaint Questionnaire (FCQ) in a sample of 40 patients with schizophrenia. Trauma-related symptoms were assessed concurrently using the Trauma Symptom Checklist-40, symptoms of dissociation using the Dissociative Experiences Scale, and sensitization phenomena using the Complex Partial Seizure-like Symptoms Inventory and Limbic System Checklist-33. Psychotic symptoms were measured by Health of the Nation Outcome Scales. The dosage of antipsychotic medication was assessed in terms of equivalents of chlorpromazine, and antidepressant medication in terms of equivalents of fluoxetine. Spearman correlations were performed to explore the relationship between FCQ and other trauma-related measures. To determine the relative contributions of trauma-related symptoms to basic symptoms a linear regression analysis was performed. Results: The results showed that higher levels of basic symptoms of schizophrenia were associated with greater levels of symptoms of dissociation, traumatic stress, and sensitization or kindling-like processes in schizophrenia. Among the trauma-related variables, sensitization phenomena assessed with Complex Partial Seizure-like Symptoms Inventory were closely associated with basic symptoms. Discussion: These results indicate that basic symptoms measured by FCQ might be related to trauma. The potential of trauma to influence neurodevelopmental hypotheses of schizophrenia is discussed.Item Clinical and Psychological Correlates of Two Domains of Hopelessness in Schizophrenia(2008-12) Lysaker, Paul H.; Salyers, Michelle P.; Tsai, Jack; Spurrier, Linda Yorkman; Davis, Louanne W.Hopelessness is a widely observed barrier to recovery from schizophrenia spectrum disorders. Yet little is known about how clinical, social, and psychological factors independently affect hope. Additionally, the relationships that exist between these factors and different kinds of hope are unclear. To explore both issues, we correlated two aspects of hope, expectations of the future and agency, with stigma, clinical symptoms, anxiety, and coping preferences in 143 persons with a schizophrenia spectrum disorder. Multiple regressions revealed that hope for the future was predicted by lesser alienation, lesser preference for ignoring stressors, and lesser emotional discomfort and negative symptoms, accounting for 43% of the variance. A greater sense of agency was linked to lesser endorsement of mental illness stereotypes, fewer negative symptoms, lesser social phobia, and lesser preference for ignoring stressors, accounting for 44% of the variance. Implications for research and interventions are discussed.Item Co-occurring Deficits in Clinical and Cognitive Insight in Prolonged Schizophrenia- Spectrum Disorders: Relationship to Metacognitive Deficits(Oxford University Press, 2021-07-20) Mervis, Joshua E.; Bonfils, Kelsey A.; Cooper, Samuel E.; Wiesepape, Courtney; Lysaker, Paul H.; Psychiatry, School of MedicinePeople diagnosed with schizophrenia have been broadly observed to experience deficits in clinical and cognitive insight; however, less is understood about how these deficits are related. One possibility is that these deficits co-occur among people when other deficits in cognition are present, such as in executive function, social cognition, and metacognition, which may either promote the development of both forms of poor insight or allow one to negatively influence the other. To explore this possibility, we conducted a cluster analysis using assessments of clinical and cognitive insight among 95 adults with a schizophrenia spectrum disorder. As predicted, this analysis yielded a group with concurrently poor clinical and cognitive insight (n = 36). Additional groups were found with concurrently good clinical and cognitive insight (n = 28) and poor clinical insight and good cognitive insight (n = 31). Groups were then compared on assessments of executive function, social cognition, and metacognition. The group with concurrently lower levels of cognitive and clinical insight had significantly poorer metacognition relative to the other groups. In particular, they tended to form more fragmented and less integrated ideas about themselves and others. No differences were found for executive function or social cognition. The result may suggest that while clinical and cognitive insight is partially orthogonal phenomena, relatively lower levels of metacognition, or difficulties forming integrated ideas about oneself and others, maybe a condition leading to the confluence of lower clinical and cognitive insight. Interventions targeting metacognition may be of particular use for this group.Item A cognitive model of diminished expression in schizophrenia: The interface of metacognition, cognitive symptoms and language disturbances(Elsevier, 2020-12) García-Mieres, Helena; Lundin, Nancy B.; Minor, Kyle S.; Dimaggio, Giancarlo; Popolo, Raffaele; Cheli, Simone; Lysaker, Paul H.; Psychology, School of ScienceThe 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 (β = -.073, p = .008, ±95% CI [-0.126, -0.019]). and fully mediated the influence of cognitive symptoms in diminished expression (β = 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.
