Can a Theory of Mind Disruption Help Explain OCD Related Metacognitive Disturbances?

The link between anxiety and theory of mind in children: A meta-analysis

BACKGROUND

The ability to reason about someone else's mental states, an ability known as theory of mind, is essential to help children navigate social life. However, not all children are socially skilled. Given socialisation is key for healthy development in children, finding what might exacerbate these difficulties is important. Emerging research suggests a potential link between anxiety and theory of mind abilities in children. This meta-analysis aims to characterise that link.

METHOD

Four electronic databases were systematically searched to identify relevant studies. Search terms included variations of terms for theory of mind, anxiety, and children. Studies were screened with inclusion and exclusion criteria for eligibility and identified papers were appraised on quality.

RESULTS

The search returned 3674 papers of which 20 were included in the analysis. These included a total of 3110 participants, aged 4-19. Overall, it was found that anxiety had a negative relationship with theory of mind and this appeared to be more pronounced in theory of mind processes related to affective states. There were no differences in the negative relationship between subtypes of anxiety or between studies with autistic and neurotypical children.

CONCLUSION

The findings suggest that anxious children may have difficulties using theory of mind abilities. Heterogeneity was substantial in the data, which limits the confidence in conclusions. Quality appraisal identified that the quality of theory of mind and anxiety measures varied between studies.

Pathways to orthorexia nervosa: a case series discussion

BACKGROUND

Orthorexia nervosa (ON) has gained increasing interest in the last 2 decades. Although a consensus on the diagnostic boundaries of ON has not yet been reached, there is some evidence for an overlap with eating disorders, obsessive-compulsive disorder, and psychotic disorder. Most of the knowledge about ON has emerged from studies of non-clinical and at-risk populations and is focused on differential diagnosis; therefore, further clinical studies are needed to better outline the ON phenomenon in a real-life setting.

OBJECTIVE

This case series aims at describing clinical cases that developed symptoms suggestive of ON after being diagnosed with a prior psychiatric disorder and then discussing them in light of possible clinical pathways.

METHODS

Four women consecutively admitted to an outpatient unit for the treatment of eating disorders were diagnosed with ON through a clinical interview, according to Dunn and Bratman's criteria and self-administered questionnaire assessment (ORTO-15), and were considered to be eligible for this case series study. Psychiatric anamnestic data were collected retrospectively.

RESULTS

The anamnesis revealed that all patients were previously diagnosed with a psychiatric disorder (i.e. obsessive-compulsive disorder, bulimia nervosa, illness anxiety disorder, and psychotic disorder) before developing ON.

CONCLUSION

Past literature focused on differential diagnosis between ON and other psychiatric disorders. This is the first description of clinical cases in a real-life setting that started with different psychiatric disorders and later developed symptoms suggestive of ON. These cases have generated a new research question on the possibility that different psychiatric disorders may associate with a later onset of ON.

Childhood trauma in obsessive compulsive disorder: the roles of alexithymia and attachment

OBJECTIVE

The aim of this study was to investigate the interrelationships between childhood trauma, attachment, alexithymia, and the severity of obsessive compulsive disorder (OCD) in a cohort of participants with OCD.

RATIONALE

There is a growing body of research linking traumatic experiences in childhood with the development of OCD. The mechanisms involved in this association are not yet clear.

METHODS

The sample was comprised of 82 people with OCD and 92 comparison participants. A cross-sectional design was used, utilizing internet-mediated administration of the Childhood Trauma Questionnaire - revised (CTQ-R); the Yale-Brown Obsessive Compulsive Scale - Self-Report (Y-BOCS-SR); the Experiences in Close Relationships Scale (ECR); and Toronto Alexithymia Scale (TAS-20). Partial least squares (PLS) analysis was used to determine significant paths between the constructs.

RESULTS

Results of PLS analysis supported all of the hypotheses made: there was a significant positive correlation between childhood trauma and attachment avoidance, which in turn was significantly positively associated with alexithymia. Alexithymia was significantly associated with the severity of OCD symptoms and the number of OCD symptoms. Mediational analysis showed that alexithymia significantly carried an influence from attachment avoidance to the severity of obsessions and the number of obsession symptoms.

CONCLUSIONS

There is a relationship between childhood trauma and OCD, however this relationship is not direct in nature but is influenced by peoples' past experiences with significant others and associated difficulties in emotional processing.
