Parent-report measure of Theory of Mind: Adaptation to Polish of the Children’s Social Understanding Scale

The main aim of the study was to investigate whether the Children’s Social Understanding Scale (CSUS), a parent report technique, is a valid and reliable measure of Theory of Mind (ToM) abilities in Polish-speaking children. Additionally, the role of language abilities in ToM development was explored. A group of 225 parents of approximately 3.5-year-old Polish children was tested using the Polish version of the CSUS. Their children were tested with a word comprehension test and five behavioural ToM tasks. Satisfactory psychometric properties of the Polish CSUS were observed and positive correlations between the CSUS and behavioural ToM tasks were found. A two-factor structure was found in the CSUS: Mental State Talk (MST) and Mental State Comprehension. The MST factor was significantly related to word comprehension. The utility of the Polish version of the CSUS for future cross-cultural research with this population is discussed.     

Seeking a Common Framework for Research on Narcissism: An Attempt to Integrate the Different Faces of Narcissism Within the Circumplex of Personality Metatraits

The current paper presents a proposal for integrating different narcissism constructs (grandiose, vulnerable, communal, and collective) within the Circumplex of Personality Metatraits (CPM), an integrative model of personality structure that could also be used to accommodate the narcissism spectrum model. The study was conducted on a community sample (N = 781 adults). The theoretically predicted locations of the different narcissism constructs within the CPM space were empirically verified using the structural summary method. We found that grandiose, vulnerable, and communal narcissism can be meaningfully located within the CPM, while the status of collective narcissism remains unclear. Thus, the CPM can serve as a personality matrix explaining the differences and similarities between the various faces of narcissism. © 2019 European Association of Personality Psychology
