The impact of treatment delivery format on response to cognitive behaviour therapy for preadolescent children with anxiety disorders

Background: Multiple sclerosis (MS) is commonly associated with psychological complications. Previous research by Hayter and colleagues (2016) found that in patients with MS, health anxiety (HA) can account for part of the variance in quality of life (QoL) independent of physical and cognitive impairment caused by the disease. MS patients with HA perceived their intact physical and cognitive performance as impaired relative to those without HA and attributed the impairment to MS. These misperceptions might be useful targets in the treatment of HA in MS using cognitive behaviour therapy (CBT). Aims: Study 1 sought to replicate the main findings from Hayter et al. (2016). Study 2 examined the impact of HA-focused CBT in a case series. Method: In Study 1, twenty participants with MS were screened for HA and assigned to either a high or low HA group. They completed assessments of cognitive and physical functioning before rating their performance on these tasks, followed by measures of QoL, mood and physical disability. Four participants in the high HA group subsequently received six sessions of CBT using a consecutive AB case series in Study 2. Results: Study 1 replicated the main findings from the earlier study. In Study 2, three of the four patients who received treatment showed substantial improvements in HA and mood and all showed improvement in QoL. Conclusion: Given the high rates of HA in MS patients and its impact on QoL, this case series suggests that a brief CBT intervention could significantly improve patients’ wellbeing.

Abstract Anxiety disorders that are the most commonly occurring psychiatric disorders in childhood, are associated with a range of social and educational impairments and often continue into adulthood. Cognitive behaviour therapy (CBT) is an effective treatment option for the majority of cases, although up to 35–45% of children do not achieve remission. Recent research suggests that some genetic variants may be associated with a more beneficial response to psychological therapy. Epigenetic mechanisms such as DNA methylation work at the interface between genetic and environmental influences. Furthermore, epigenetic alterations at the serotonin transporter (SERT) promoter region have been associated with environmental influences such as stressful life experiences. In this study, we measured DNA methylation upstream of SERT in 116 children with an anxiety disorder, before and after receiving CBT. Change during treatment in percentage DNA methylation was significantly different in treatment responders vs nonresponders. This effect was driven by one CpG site in particular, at which responders increased in methylation, whereas nonresponders showed a decrease in DNA methylation. This is the first study to demonstrate differences in SERT methylation change in association with response to a purely psychological therapy. These findings confirm that biological changes occur alongside changes in symptomatology following a psychological therapy such as CBT.
