Emotion regulation in adults with Klinefelter syndrome (47,XXY): Neurocognitive underpinnings and associations with mental health problems

OBJECTIVES: The aim of this study is to evaluate if language and executive functioning deficits in individuals with the 47,XXY chromosomal pattern contribute to emotion regulation problems and related symptoms of psychopathology. METHODS: A group of 26 adult men with 47,XXY completed measures of cognitive emotion regulation strategies, neurocognitive functioning, and symptoms of psychopathology. RESULTS: Atypical emotion regulation strategies were found in the XXY group, with increased expression of emotions (69%), avoiding (65%), distraction seeking (54%), and passive coping (54%). More difficulties in mental flexibility and attention regulation, and speeded responding were associated with more pronounced emotion expression (emotional outbursts). Emotion regulation problems were associated with symptoms of anxiety, depression, thought problems, and hostility. CONCLUSION: This study has identified emotion regulation as a potential target for treatment and intervention, with a specific focus on executive functions in the management of emotions in individuals with 47,XXY.
