RESUMEN
OBJECTIVE: Loneliness is a concern for patients with schizophrenia. However, the correlates of loneliness in patients with schizophrenia are unclear; thus, the aim of the study is to investigate neuro- and social cognitive mechanisms associated with loneliness in individuals with schizophrenia. METHOD: Data from clinical, neurocognitive, and social cognitive assessments were pooled from two cross-national samples (Poland/USA) to examine potential predictors of loneliness in 147 patients with schizophrenia and 103 healthy controls overall. Furthermore, the relationship between social cognition and loneliness was explored in clusters of patients with schizophrenia differing in social cognitive capacity. RESULTS: Patients reported higher levels of loneliness than healthy controls. Loneliness was linked to increased negative and affective symptoms in patients. A negative association between loneliness and mentalizing and emotion recognition abilities was found in the patients with social-cognitive impairments, but not in those who performed at normative levels. CONCLUSIONS: We have elucidated a novel mechanism which may explain previous inconsistent findings regarding the correlates of loneliness in individuals with schizophrenia.

While considerable emphasis has been put on investigating the mechanisms that drive reduced social connection in patients with schizophrenia (SCZ), recent studies have increasingly focused on the issue of loneliness in SCZ. As both social cognitive bias and self-reported empathy predict loneliness in non-clinical populations, the current study aims to examine the relationship between loneliness, reduced social connection and social cognitive biases, and self-reported empathy in SCZ. Ninety-three adult SCZ and sixty-six matched healthy individuals completed a battery of questionnaires measuring loneliness and social connection (Revised-UCLA Loneliness Scale, Lubben-Social Network Scale, Social Disconnectedness Scale), cognitive biases (Ambiguous Intentions Hostility Questionnaire, Davos Assessment of Cognitive Biases Scale, Cognitive Biases Questionnaire for psychosis) and self-reported empathy (Interpersonal Reactivity Index). Significant predictors of loneliness in SCZ were entered into two latent variables ("Social Threat Bias", "Social Connection"), and structural equation modeling was used to explore the direct and indirect relationships between Social Threat Bias, symptoms. and loneliness in SCZ. Patients reported higher levels of loneliness, cognitive biases and personal distress compared to controls. Furthermore, SCZ reported less social connection and perspective taking compared to controls. Structural equation modeling revealed that Social Threat Bias was linked to increased loneliness in SCZ both directly and indirectly via decreased social connection. Negative symptoms were directly linked with loneliness, while the association between affective symptoms and loneliness was mediated via Social Threat Bias. The results of the current study suggest that social threat bias should be considered while planning the interventions aimed to reduce loneliness in schizophrenia.

Social cognitive deficits are currently considered as one of the main predictors of clinical symptoms and functional outcome in patients with schizophrenia. Multiple studies have suggested that a two-factor solution (low-level vs. high-level) best describes the structure of social cognitive processes in patients. While higher-order processes have been repeatedly linked to negative symptoms, no such association was found for lower-level processes. Thus, the aim of the current study is to examine whether the association between basic social perception processes and symptoms in patients with schizophrenia is mediated by mentalizing abilities. One hundred thirty-nine patients have completed basic social perception (Communicative Interactions Database task CID-12) and mentalizing (Reading the Mind in the Eyes task) tasks. In line with our hypothesis, we have observed full mediation of the effects of basic social perception abilities on negative symptoms via mentalizing abilities in patients. This effect suggests that, similarly as in the case of positive symptoms, a hierarchical nature of social cognitive processes should be considered while investigating negative symptoms of schizophrenia.

A significant body of research supports the relationship between religious attendance, objective and subjective social networks characteristics, and mental well-being. This trajectory may be particularly important in the wake of the COVID-19 crisis. Thus, the current study examined the relationship between religious attendance, social network characteristics, loneliness, and mental well-being in a sample of 564 young adults (aged 18-35 years) soon after the first COVID-19-related restrictions were imposed in Poland. In line with previous findings, both frequent (FAs) and infrequent religious attenders (IAs) reported more people in their social networks compared to non-attenders (NAs). Further analysis revealed full mediation of religious attendance (FAs vs. NAs) via social network size on loneliness and mental well-being. This pattern of results was still observed after the exclusion of worship-based affiliates from the social network score. A follow-up survey carried out one year later (N = 94) showed that all three groups of participants (FAs, IAs, and NAs) reported increased loneliness and decreased mental well-being. Taken together, these findings show that the influence of religious attendance on social functioning cannot be attributed solely to congregational relationships.
