Show moreObjectives: Art therapy (AT) as a treatment option for anxiety is regularly employed in clinical practice, but scientific evidence for its effectiveness is lacking, since this intervention has hardly been studied. The aim was to study the effectiveness of AT on anxiety in adult women. The specific type of AT studied was anthroposophic AT.Methods: A RCT comparing AT versus a waiting list (WL) condition on anxiety symptom severity, quality of life, and emotion regulation. Factors influencing treatment outcome were additionally explored. Participants were women, aged 18–65 years, diagnosed with generalized anxiety disorder, social anxiety disorder or panic disorder, with moderate to severe anxiety symptoms. The trial was registered in the Dutch Trial Registration (NL6661).Results: Fifty-nine women were included, of which 47 completed the trial. Both per-protocol and intention-to treat analyses demonstrated effectiveness of AT compared to WL, showing a reduction in anxiety, an increase in subjective quality of life (both with large effects) and an improvement in accessibility of emotion regulation strategies (medium effect). Treatment effects remained after 3 months follow-up. Improved acceptance of emotions and improved goal-oriented action are aspects of emotion regulation that are associated with the decrease in anxiety level.Conclusion: AT is effective in reducing anxiety symptoms, improving quality of life and aspects of emotion regulation. Future RCTs should use active controls (treatment as usual) and study cost-effectiveness. Show less

Show moreAbout 1 in 650 boys are born with an extra X chromosome (47,XXY or Klinefelter syndrome). 47,XXY is associated with vulnerabilities in socio‐emotional development. This study was designed to assess types of cognitive deficits in individuals with 47,XXY that may contribute to social‐emotional dysfunction, and to evaluate the nature of such deficits at various levels: ranging from basic visuospatial processing deficits, impairments in face recognition (FR), to emotion expression impairments. A total of 70 boys and men with 47,XXY, aged 8 to 60 years old, participated in the study. The subtests feature identification, FR and identification of facial emotions of the Amsterdam Neuropsychological Tasks were used. Level of intellectual functioning was assessed with the child and adult versions of the Wechsler Intelligence Scales. Reaction time data showed that in the 47,XXY group, 17% had difficulties in visuospatial processing (no social load), 26% had difficulties with FR (medium social load) and an even higher number of 33% had difficulties with facial expressions of emotions (high‐social load). Information processing impairments increased as a function of “social load” of the stimuli, independent of intellectual functioning. Taken together, our data suggest that on average individuals with XXY may have more difficulties in information processing when “social load” increases, suggesting a specific difficulty in the higher‐order labeling and interpretation of social cues, which cannot be explained by more basic visuospatial perceptual skills. Considering the increased risk for social cognitive impairments, routine assessment of social cognitive functioning as part of neuropsychological screening is warranted. Show less

Show moreBackground: Several genetic mechanisms have been proposed for the variability of the Klinefelter syndrome (KS) phenotype such as the parent-of-origin of the extra X chromosome. Parent-of-origin effects on behavior in KS can possibly provide insights into X-linked imprinting effects on psychopathology that may be extrapolated to other populations. Here, we investigated whether the parent-of-origin of the supernumerary X chromosome influences autistic and schizotypal symptom profiles in KS. Methods: Parent-of-origin of the X chromosome was determined through analysis of the polymorphic CAG tandem repeat of the androgen receptor gene. Autistic traits (Autism Diagnostic Interview-Revised) were measured in a younger KS sample (n = 33) with KS and schizotypal traits (Schizotypal Personality Questionnaire) were assessed in an older KS sample (n = 43). Scale scores on these questionnaires were entered in statistical analyses to test parent-of-origin effects. Results: The results show that parent-of-origin of the X chromosome is reflected in autistic and schizotypal symptomatology. Differences were shown in the degree of both schizotypal and autistic symptoms between the parent-of-origin groups. Furthermore, the parent-of-origin could be correctly discriminated in more than 90% of subjects through Autism Diagnostic Interview-Revised scales and in around 80% of subjects through Schizotypal Personality Questionnaire scales. Conclusions: These findings point to parent-of-origin effects on psychopathology in KS and indicate that imprinted X chromosomal genes may have differential effects on autistic and schizotypal traits. Further exploration of imprinting effects on psychopathology in KS is needed to confirm and expand on our findings. Show less
