The group format of the Unified Protocol for Transdiagnostic Treatment of Emotional Disorders (UP) shows promise as a efficient method for delivering established and effective psychological treatments for emotional disorders. The implementation of psychological treatment in a group format varies according to a country’s local circumstances, policies, and culture. To date, there are no comprehensive reviews of aspects related to settings, participants, providers, and interventions for applying the UP in a group context. Therefore, we have prepared a scoping review protocol to clarify the fields, participant characteristics, intervention structures, and therapist training methods related to group-format UP, aiming to facilitate its implementation across diverse regions and contexts. Based on this protocol, the scoping review will follow the Joanna Institute guidelines and PRISMA statement extensions for scoping reviews. The review will include studies of the group format of UP that describe symptoms of emotional disorders in adults. The following databases will be searched: PubMed, MEDLINE, Web of Science, PsycINFO, and ClinicalTrials.gov. The selected data will be organized according to four predefined research questions. This scoping review will provide suggestions to promote the application and implementation of the UP in a group format and contribute to disseminating evidence-based psychological treatment.

ABSTRACT The network approach offers a novel perspective for conceptualizing the psychopathology of social anxiety disorder (SAD). This scoping review aimed to map the existing literature on the psychometric network structures of social anxiety symptoms and identify future research directions. A total of 61 studies were identified through searches in PubMed, PsycINFO, ScienceDirect, Cochrane Library, ClinicalTrials.gov and the Open Science Framework databases, employing the keywords (‘social anxiety disorder’ OR ‘social phobia’ OR ‘social anxiety’) AND (‘network analysis’). Of these, 10 studies examined the network structures of social anxiety symptoms in patients with SAD, 17 investigated such structures in individuals without an SAD diagnosis and 34 explored networks of other symptoms that included social anxiety symptoms. Most studies were conducted on Western and Chinese populations, underscoring the need for broader cross‐cultural comparisons. The central symptoms in SAD networks were fear and anxiety related to performing and interacting with groups, engaging with strangers or unfamiliar individuals, participating in events and being the center of attention. However, the network structures of SAD and related symptoms remain underexplored, with existing studies offering only partial insights. This review emphasizes the need for future research to comprehensively assess social anxiety symptoms and adopt cross‐cultural comparative designs to deepen the understanding of SAD psychopathology. These findings provide a foundation for future research on SAD utilizing network analysis.

Background This study developed the Japanese version of the Auckland Individualism and Collectivism Scale (J-AICS), examined its reliability and validity, and explored the associations between its factors (compete, unique, responsibility, advice, and harmony) along with variables related to mental health in the Japanese population. Methods We recruited 476 Japanese participants from the general population. Participants completed the J-AICS along with questionnaires pertaining to culture and mental health. Results Confirmatory factor analysis indicated the correlated five-factor model showed a good fit to the data. The Cronbach’s α and McDonald’s ω coefficients were high for the individualism, collectivism, compete, unique, and advice factors, but low for the responsibility and harmony factors. Convergent validity was supported by significant relationships between culture-related variables. A one-way analysis of variance revealed the low individualism/collectivism cluster had higher loneliness and lower satisfaction with life than the high individualism and collectivism clusters. The multiple regression analyses showed that the responsibility factor was significantly and negatively associated with mental health concerning anxiety and depressive symptoms, loneliness, and satisfaction with life. In addition, the harmony factor was significantly and positively associated with the mental health. Conclusion These findings demonstrate sufficient validity of the J-AICS; however, reliability was insufficient for responsibility and harmony. Further, responsibility was positively associated with mental health and harmony was negatively associated with mental health.
