RESUMO

BACKGROUND: Schizophrenia (SZ) and autism spectrum disorders (ASD) are characterized by difficulties in theory of mind (ToM). We examined group differences in performance on a ToM-related test and associations with an estimated IQ. METHODS: Participants [N = 1227, SZ (n = 563), ASD (n = 159), and controls (n = 505), 32.2% female] completed the Reading the Mind in the Eyes Test (RMET) and assessments of cognitive ability. Associations between IQ and group on RMET were investigated with regression analyses. RESULTS: SZ (d = 0.73, p < 0.001) and ASD (d = 0.37, p < 0.001) performed significantly worse on the RMET than controls. SZ performed significantly worse than ASD (d = 0.32, p = 0.002). Adding IQ to the model, SZ (d = 0.60, p < 0.001) and ASD (d = 0.44, p < 0.001) continued to perform significantly worse than controls, but no longer differed from each other (d = 0.13, p = 0.30). Small significant negative correlations between symptom severity and RMET performance were found in SZ (PANSS positive: r = -0.10, negative: r = -0.11, both p < 0.05). A small non-significant negative correlation was found for Autism Diagnostic Observation Schedule scores and RMET in ASD (r = -0.08, p = 0.34). CONCLUSIONS: SZ and ASD are characterized by impairments in RMET. IQ contributed significantly to RMET performance and accounted for group differences in RMET between SZ and ASD. This suggests that non-social cognitive ability needs to be included in comparative studies of the two disorders.

RESUMO

BACKGROUND: Loneliness impedes recovery from mental illness. Despite increased interest in loneliness in psychosis, qualitative methods are underused in clinical research on this topic. AIMS: We used qualitative interviews to explore loneliness among persons with schizophrenia spectrum disorders (SSDs). We examined which aspects of living with psychosis were associated with the experience of loneliness, including symptomatology, social relationships, and disruptions in school/work. METHODS: Sixteen participants diagnosed with SSDs engaged in semi-structured, qualitative interviews about loneliness. Participants commented on current activities and social relationships, including their perceptions of the quantity, quality and types of relationships. Important demographic and clinical information was acquired through communication with participants and/or through medical record review. Thematic analysis was used to examine interview content. RESULTS: Our analyses revealed four key topic areas and several sub-themes related to loneliness across participants, including aspects of the physical environment (e.g. financial limitations), social context (e.g. lacking a romantic partner), and psychological functioning (e.g. psychotic/symptoms) that impact lonely feelings. Participants commented on coping strategies to manage loneliness and provided suggestions for possible interventions. CONCLUSIONS: Persons diagnosed with SSDs report significant and impactful feelings of loneliness. This study highlights the need for novel and effective treatments targeting loneliness in this population.

RESUMO

BACKGROUND: Premature mortality in individuals with schizophrenia spectrum disorders (SSDs) is largely due to high rates of chronic health conditions. Although exercise has been shown to improve health in this population, scalable and accessible interventions are limited. AIM: To examine the impact of Physical Activity Can Enhance Life (PACE-Life), a novel walking intervention, on physical activity, and on secondary outcomes of cardiorespiratory fitness (CRF), physical health, autonomous motivation, social support, and quality of life. METHOD: Sixteen individuals with SSDs were enrolled in a 10-week open trial. The intervention included walking groups, home-based walks, Fitbit use, and goal-setting and if-then plans. Within-group effect sizes were calculated to represent changes from baseline to post-test and 1-month follow-up. RESULTS: Participants increased self-reported weekly walking minutes and decreased daily hours spent sitting; however, Fitbit-recorded exercise behavior changed only minimally. There were also improvements in secondary outcomes including autonomous motivation and hip circumference. CRF improved only minimally, and findings were relatively unchanged with outliers removed from the full sample. CONCLUSIONS: This open trial demonstrates modest improvements in key parameters of exercise behavior and physical health from participating in PACE-Life. Future research should assess the efficacy of this intervention in a randomized controlled trial.

RESUMO

BACKGROUND: Autism spectrum disorder (ASD) and schizophrenia (SCZ) are separate neurodevelopmental disorders that are both characterized by difficulties in social cognition and social functioning. Due to methodological confounds, the degree of similarity in social cognitive impairments across these two disorders is currently unknown. This study therefore conducted a comprehensive comparison of social cognitive ability in ASD and SCZ to aid efforts to develop optimized treatment programs. METHODS: In total, 101 individuals with ASD, 92 individuals with SCZ or schizoaffective disorder, and 101 typically developing (TD) controls, all with measured intelligence in the normal range and a mean age of 25.47 years, completed a large battery of psychometrically validated social cognitive assessments spanning the domains of emotion recognition, social perception, mental state attribution, and attributional style. RESULTS: Both ASD and SCZ performed worse than TD controls, and very few differences were evident between the two clinical groups, with effect sizes (Cohen's d) ranging from 0.01 to 0.34. For those effects that did reach statistical significance, such as greater hostility in the SCZ group, controlling for symptom severity rendered them non-significant, suggesting that clinical distinctions may underlie these social cognitive differences. Additionally, the strength of the relationship between neurocognitive and social cognitive performance was of similar, moderate size for ASD and SCZ. CONCLUSIONS: Findings largely suggest comparable levels of social cognitive impairment in ASD and SCZ, which may support the use of existing social cognitive interventions across disorders. However, future work is needed to determine whether the mechanisms underlying these shared impairments are also similar or if these common behavioral profiles may emerge via different pathways.

RESUMO

INTRODUCTION: Persons diagnosed with schizophrenia spectrum disorders (SSDs) often experience pervasive feelings of loneliness, which are considered a significant barrier to treatment and recovery. AIM: As impaired social cognition may contribute to increased loneliness and less skillful social interactions, this study examines the relationships between loneliness and measures of social cognition and functional outcome from the Social Cognition Psychometric Evaluation (SCOPE) study. METHODS: This study evaluated the relationship between loneliness, social cognitive ability, and social functioning in the context of a large-scale psychometric investigation. We also explored the associations of select demographic characteristics and clinical variables on the endorsement of loneliness in persons diagnosed with a psychotic disorder. RESULTS: Seventy-four stable outpatients with SSDs and 58 healthy controls completed the UCLA Loneliness Scale in addition to the standard SCOPE battery. Our findings support prior research indicating persons diagnosed with a psychotic disorder experience greater levels of loneliness than normative groups. However, the results also indicate that self-reported loneliness is not associated with social cognitive abilities or functional outcome in psychosis. Regression analyses indicate that roughly half the variance in loneliness endorsed by persons with SSDs is accounted for by clinical variables, with loneliness most strongly associated with guilt and self-esteem. CONCLUSION: These findings suggest that treatments aiming to reduce perceived social isolation in psychosis should incorporate techniques to bolster selfesteem, reduce guilt, and improve depressive symptoms.

RESUMO

The health benefits of exercise are well documented, yet annual health care costs related to physical inactivity are well within the billions. Furthermore, individuals with schizophrenia spectrum disorders (SSDs) are more likely to lead sedentary lives, exercise less than the general population, and die prematurely from preventable causes. Previous research examining the effects of exercise on individuals with SSDs has been encouraging yet limited in creating accessible and sustainable interventions. The current pilot study developed and evaluated the impact of Work out by Walking (WOW), a multicomponent group walking intervention on the health of 16 individuals with SSDs. Results indicated improvements in indicators of physical health, activity level, social support, and mental health and a high level of program satisfaction. Future research should examine multicomponent group walking programs for individuals with SSDs in larger samples and with the inclusion of a comparison condition.

RESUMO

Objectives: The current study sought to qualitatively characterize the experiences of American users in a recent open trial of the Horyzons digital platform. Methods: In total, 20 users on Horyzons USA completed semistructured interviews 12 weeks after their orientation to the platform and addressed questions related to (1) the platform, (2) their online therapist, and (3) the peer workers and community space. A hybrid inductive-deductive coding strategy was used to conduct a thematic analysis of the data (NCT04673851). Results: The authors identified seven prominent themes that mapped onto the three components of self-determination theory. Features of the platform itself as well as inter- and intra-personal factors supported the autonomous use of Horyzons. Users also reflected that their perceived competence in social settings and in managing mental health was increased by the familiarity, privacy, and perceived safety of the platform and an emphasis on personalized therapeutic content. The behaviors or traits of online therapists as perceived by users and regular contact with peers and peer support specialists satisfied users' need for relatedness and promoted confidence in social settings. Users also described aspects of Horyzons USA that challenged their satisfaction of autonomy, competence, and relatedness, highlighting potential areas for future iterations of the platform's content and interface. Conclusions: Horyzons USA is a promising digital tool that provides young adults with psychosis with the means to access tailored therapy material on demand and a supportive digital community to aid in the recovery process.

RESUMO

Measurement-based care (MBC) involves the regular administration of outcome assessments to track and evaluate treatment progress and requires psychometrically sound instruments. While there are widely used patient-reported outcome measures (PROMs) for several psychiatric disorders and symptom categories (e.g., depression, anxiety), there is less consensus about self-report assessments for measurement-based care of schizophrenia. The present review provides an initial guide to this area by reporting on psychometric studies that introduce or evaluate PROMs designed for the ongoing treatment of schizophrenia. Out of an initial database of 6,153 articles, and review of 141 full-text articles, an analysis of 21 articles examining 12 measures is presented in this review. Findings suggest robust options exist for clinical and research institutions aiming to assess symptom outcomes in schizophrenia, with most measures showing strengths in internal consistency, test-retest reliability, and a number of measures with evidence of convergent or criterion validity. While there exist heterogeneous options, multiple measures demonstrated promising psychometric strengths. Future work validating consistent psychometric validity could involve measures which could be valuable in context of MBC for schizophrenia.

RESUMO

AIM: We evaluated the feasibility and acceptability of Horyzons, an online social media platform designed to facilitate relationship development among, and introduce therapeutic content to, first-episode psychosis (FEP) clients. We also evaluated whether participation in the platform was related to reduced loneliness, improved social integration and increased psychological well-being. METHODS: Twenty-six participants diagnosed with a schizophrenia spectrum disorder were provided access to the moderated Horyzons platform for 12 weeks. During the intervention period, participants were encouraged to access therapeutic content and social components embedded within the site. Participants were recruited from three first-episode coordinated specialty care clinics in North Carolina and assessed at four time points: baseline, mid-treatment, post-treatment and 1-month follow-up. RESULTS: Findings indicated that Horyzons was both feasible and very well tolerated, with a 92.3% retention rate and 79.2% of participants actively engaged in the platform. The most commonly identified personal strengths selected by Horyzons users were creativity (61.5%), curiosity (42.3%) and courage (38.5%). Feedback from participants indicated Horyzons could be improved by the development of a smartphone application, expanding the size of the Horyzons community and facilitating private messages between users. Preliminary results with engaged participants showed the greatest improvements in psychosis-related symptoms, followed by self-reported experience of negative emotions, depressive symptoms and loneliness. CONCLUSIONS: This open trial found that Horyzons is both feasible and acceptable to FEP persons early in the course of illness living in the United States.

RESUMO

OBJECTIVE: The Social Cognition Psychometric Evaluation (SCOPE) study supported the utility and practicality of the Hinting task as a measure of social cognition/mentalizing in clinical trials, specifically with the SCOPE authors' stringent scoring system. However, it remains unclear whether the SCOPE scoring system is necessary for the task to be judged as psychometrically sound. METHOD: Independent raters rescored data from the three phases of SCOPE using the Hinting task's original scoring criteria. Psychometric properties of the task when scored with the original criteria versus more stringent SCOPE criteria were compared in a large sample of individuals with chronic schizophrenia (n = 397) and matched controls (n = 300) as well as a smaller sample of individuals with early psychosis (n = 38) and controls (n = 39). RESULTS: In both samples, SCOPE criteria resulted in lowered average scores and reduced ceiling effects. Further, revised scoring resulted in strengthened relationships between the hinting task and outcome measures in the chronic sample, and better differentiated early psychosis patients from controls. Conversely, test-retest reliability and internal consistency estimates were not improved using revised scoring and remained suboptimal, particularly for healthy controls. CONCLUSION: Overall, SCOPE scoring criteria improved some psychometric properties and clinical utility, suggesting that these criteria should be considered for implementation.

RESUMO

Although social cognition is frequently identified as a target in clinical trials and psychosocial interventions for adults with autism spectrum disorder (ASD), these efforts are hampered by a lack of consensus and validation of social cognitive measures. The current study provides psychometric evaluation of 11 frequently used measures encompassing different subdomains of social cognition. Adults with autism (N = 103) and typically developing controls (N = 95) completed 11 commonly used social cognitive tasks spanning the domains of emotion processing, social perception, and mentalizing/theory of mind. We examined each measure's internal reliability and sensitivity to group differences, how performance related to general intellectual ability, and alignment of measures with a proposed two-factor structure of social cognition in ASD. Controls outperformed the ASD group on 8 of the 11 social cognitive tasks, with the largest group differences occurring on two mentalizing measures, The awareness of social inference task (TASIT) and hinting task. In ASD, all tasks demonstrated strong internal consistency and avoided ceiling and floor effects. Social cognitive performance was also related to, but not redundant with, intellectual functioning. We also found support for a two-factor structure of social cognition, with basic social perception and emotional processing aligning into a lower-order social perception factor, while mentalizing tasks aligned into a higher-order social appraisal factor. In sum, eight tasks showed adequate to strong psychometric properties. The psychometric data, effect size estimates, and correlations between measures reported here can be used for study planning for social cognitive interventions in autism.

LAY SUMMARY: We examined 11 tasks that measure how adults with autism perceive and interpret social information. Eight of the tasks were reliable and showed lower performance in adults with autism compared to typically-developing controls. Task performance was related to but distinguishable from IQ. These measures evaluated here may be useful in assessing the effectiveness of interventions and treatments to improve social abilities in adults with autism.

RESUMO

BACKGROUND: Evidence-based approaches and early intervention have improved the long-term prognosis of individuals with schizophrenia. However, little is known about the therapeutic processes involved in individual therapy in first-episode psychosis. A comprehensive psychosocial/psychiatric programme for this population, NAVIGATE, includes an individual therapy component, individual resiliency training (IRT). Fidelity of clinicians' adherence to the IRT protocol has been collected to ensure proper implementation of this manual-based intervention. These data can provide insight into the elements of the therapeutic process in this intervention. MATERIALS AND METHODS: To achieve this goal, we first examined the factor structure of the IRT fidelity scale with exploratory factor analysis. Second, we explored the relationships among the IRT fidelity ratings with clinician years of experience and years of education, as well as client's baseline symptom severity and duration of untreated psychosis. RESULTS AND CONCLUSIONS: Results supported a 2-factor structure of the IRT fidelity scale. Correlations between clinician years of education and fidelity ratings were statistically significant.

RESUMO

Positive psychology interventions that integrate a person's strengths into treatment result in improvements in life satisfaction and well-being. Character strengths classified within six core virtues (wisdom/knowledge, courage, humanity, justice, temperance, and transcendence) have been the subject of substantial research. Though a number of studies have been conducted in the general population, little is known about the character strengths of individuals with first episode psychosis (FEP). Moreover, positive psychology principles, in particular a focus on personal strengths, have been increasingly integrated into FEP treatment and was a core component of Individual Resiliency Training (IRT), the individual therapy component of NAVIGATE tested in the Recovery After an Initial Schizophrenia Episode Early Treatment Program. As such, the present study offers an examination of character strengths among 105 FEP clients in specialized early intervention treatment. The present study included two primary aims: 1) to conduct a descriptive analysis of character strengths of FEP individuals and 2) to examine exploratory associations between character strengths and changes in symptomatic and recovery variables over six months. Results revealed that the most commonly identified strengths were: Honesty, Authenticity, and Genuineness (40.95%), Kindness and generosity (37.14%), Fairness, equity, and justice (29.52%), Gratitude (29.52%), and Humor and playfulness (29.52%). Three virtues (Humanity, Justice, and Transcendence) were significantly associated with improvements in symptoms, psychological well-being, and interpersonal relations over six months. Overall, the present study offers a glimpse into how persons with FEP view their strengths and how certain clusters of strengths are related to important outcomes.

RESUMO

Overlapping social impairments in Autism Spectrum Disorder (ASD) and Schizophrenia (SCZ) contributed to decades of diagnostic confusion that continues to this day in some clinical settings. The current study provides the first direct and detailed comparison of social behavior in the two disorders by identifying profiles of social skill in adults with ASD (n = 54), SCZ (n = 54), and typically developing (TD) controls (n = 56) during a real-world social interaction. ASD and SCZ groups exhibited poorer social skill, both overall and on most discrete abilities, relative to the TD group. Direct comparison of ASD to SCZ revealed distinct behavioral profiles, with ASD uniquely characterized by fewer interactive behaviors, and SCZ characterized by greater impaired gaze and flat/inappropriate affective responses. Additionally, IQ was associated with both overall social skill and many discrete social skills in SCZ, but was largely unrelated to social skill in ASD. These results indicate that overlapping social deficits in ASD and SCZ are comprised of both shared and distinct social skill impairments. The largest distinctions-reduced social reciprocity but better expressivity in ASD relative to SCZ, and a greater role of IQ in social skill for SCZ than ASD-highlight disorder-specific features that can improve etiological understanding, diagnostic differentiation, and treatment strategies.

RESUMO

Social cognition is an important outcome in schizophrenia research. Unfortunately, there has been a lack of consensus regarding which measures of social cognition best capture this domain of functioning. The Social Cognition Psychometric Evaluation (SCOPE) study was developed to address the need for a battery of measures that have sound psychometric properties and can be implemented in clinical trials for individuals with chronic schizophrenia. The current study expands upon the SCOPE study by examining the psychometric properties of the eight candidate measures administered to individuals early in the course of psychosis. Thirty-eight stable outpatients with first episode psychosis and thirty-nine healthy controls completed the battery at baseline and one-month follow-up assessments. The SCOPE battery was evaluated on a collection of psychometric properties, including: (1) Reliability - including test-retest and internal consistency, (2) Between group differences, (3) Utility as a repeated measure, (4) Relationship to social and occupational functioning, (5) Incremental validity - variance in functioning beyond neurocognition, and (6) Feasibility - including practicality of administration and tolerability. Social cognition accounted for substantially more variance in functional outcome than neurocognition. Only one measure, the Hinting task, displayed adequate psychometric properties to be recommended for use in clinical research with first episode psychosis. The remaining candidate measures would require modifications before implementation or cannot be recommended for use in clinical research with first episode psychosis.

RESUMO

An emerging body of research suggests that people with schizophrenia retain the ability to implicitly perceive facial affect, despite well-documented difficulty explicitly identifying emotional expressions. It remains unclear, however, whether such functional implicit processing extends beyond emotion to other socially relevant facial cues. Here, we constructed two novel versions of the Affect Misattribution Procedure, a paradigm in which affective responses to primes are projected onto neutral targets. The first version included three face primes previously validated to elicit varying inferences of threat from healthy individuals via emotion-independent structural modification (e.g., nose and eye size). The second version included the threat-relevant emotional primes of angry, neutral, and happy faces. Data from 126 participants with schizophrenia and 84 healthy controls revealed that although performing more poorly on an assessment of explicit emotion recognition, patients showed normative implicit threat processing for both non-emotional and emotional facial cues. Collectively, these results support recent hypotheses postulating that the initial perception of salient facial information remains intact in schizophrenia, but that deficits arise at subsequent stages of contextual integration and appraisal. Such a breakdown in the stream of face processing has important implications for mechanistic models of social cognitive impairment in schizophrenia and treatment strategies aiming to improve functional outcome.

RESUMO

Social cognitive deficits in schizophrenia are well documented and related to functional outcome. Current social cognition measures are often not psychometrically validated, too heterogeneous for standardization, and focus principally on one domain of social cognition rather than the simultaneous activation of multiple domains. Also, few if any allow for personalization of stimuli and interpretation of personally evocative events. An alternative methodology that addresses these limitations is the analysis of samples of personal narratives. The present study evaluates the psychometric properties of a measure called the Narrative of Emotions Task (NET). The NET was used to assess the performance of participants with a diagnosis of schizophrenia or schizoaffective disorder and nonclinical controls. Use of the NET revealed significant impairments in the emotional narratives of participants with schizophrenia. Various NET indices were significantly related to current measures of theory of mind and emotion perception, as well as a social skills role-play, but were not related to measures of attributional style or clinician-rated functioning scales. Overall, the NET׳s psychometric properties justify further use of the narrative sampling method of social cognition assessment in this population.
