Negative symptoms, particularly the motivation and pleasure (MAP) deficits, are associated with impaired social functioning in patients with schizophrenia (SCZ). However, previous studies seldom examined the role of the MAP on social functioning while accounting for the complex interplay between other psychopathology. This network analysis study examined the network structure and interrelationship between negative symptoms (at the “symptom-dimension” and “symptom-item” levels), other psychopathology and social functioning in a sample of 269 patients with SCZ. The psychopathological symptoms were assessed using the Clinical Assessment Interview for Negative Symptoms (CAINS) and the Positive and Negative Syndrome Scale (PANSS). Social functioning was evaluated using the Social and Occupational Functioning Assessment Scale (SOFAS). Centrality indices and relative importance of each node were estimated. The network structures between male and female participants were compared. Our resultant networks at both the “symptom-dimension” and the “symptom-item” levels suggested that the MAP factor/its individual items were closely related to social functioning in SCZ patients, after controlling for the complex interplay between other nodes. Relative importance analysis showed that MAP factor accounted for the largest proportion of variance of social functioning. This study is among the few which used network analysis and the CAINS to examine the interrelationship between negative symptoms and social functioning. Our findings supported the pivotal role of the MAP factor to determine SCZ patients’ social functioning, and as a potential intervention target for improving functional outcomes of SCZ.
This study showed a negative correlation between the glutamate level in the anterior cingulate cortex and cognitive theory of mind in individuals with high level of schizotypy but not in non‐schizotypy individuals.
Cutaneous pseudolymphoma (CPL) encompasses various forms of benign lymphocytic proliferative dermatoses that mimic the clinical and/or pathological changes of lymphoma. The clinical manifestations of CPL vary due to differences in the pathogenesis, and accordingly, no specific treatment has been identified. Here, we report a case of CPL on the nose, which had a distinctive appearance and was treated successfully using a combination of intralesional interferon alpha‐1b and compound betamethasone (betamethasone sodium phosphate and betamethasone dipropionate). This combination may be a good option for localized CPLs at particular anatomical sites.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
