Anxiety Sensitivity, Obsessive Beliefs, and the Prediction of CBT Treatment Outcome for OCD

Technology supported mindfulness for obsessive compulsive disorder: The role of obsessive beliefs

The current study examined the association of OCD symptoms and OCD belief domains, for individuals engaged in Technology Supported Mindfulness training (TSM) using an EEG-based biofeedback device (called "Muse") that permits individuals to engage in home based mindfulness meditation practices. In this randomized controlled study, treatment-seeking participants with a principal DSM-5 diagnosis of OCD (N = 71) were randomly assigned to eight weeks of: 1) a meditation program involving daily use of the "Muse" device, or 2) wait list control. At weeks 1, 4, and 8, participants completed self-report measures of OCD symptoms (YBOCS: Yale-Brown Obsessive Compulsive Scale) and OCD beliefs (OBQ; OCCWG, 2005). Latent Difference Score (LDS) models indicated that there was no significant longitudinal relationship between OBQ "Responsibility/Threat" (OBQ R/T) scores and OCD symptoms. The analysis of OBQ "Perfectionism/Certainty" (OBQ P/C) and OCD symptoms demonstrated a significant reciprocal relationship between these two variables, in which OCD symptoms predicted subsequent increases in OBQ P/C and vice versa. The analysis of OBQ "Importance/Control of Thoughts" (OBQ I/C) and OCD symptoms demonstrated a significant reciprocal relationship between these two variables, in which OCD symptoms predicted subsequent increases in OBQ I/C and vice versa. The analysis of OBQ domains and EEG derived attentional changes demonstrated a significant association between OBQ P/C and Alpha band frequencies. These results clarify the association of OBQ belief domains, OCD symptom change and EEG derived indicators of attention during TSM.

Anxiety sensitivity and emotion regulation as mechanisms of successful CBT outcome for anxiety-related disorders in a naturalistic treatment setting

BACKGROUND

Numerous randomized controlled trials (RCTs) have examined the efficacy of cognitive behavioral therapy (CBT) in reducing anxiety symptoms. However, relatively fewer studies have examined the effectiveness of CBT in naturalistic treatment settings. There is even less known about the mechanisms underlying successful outcomes in naturalistic samples receiving CBT. This study aimed to examine the absolute and relative mediation of emotion regulation (ER) difficulties and anxiety sensitivity (AS) on anxiety symptom reduction.

METHODS

Participants were treatment-seeking patients (N = 247) at an outpatient anxiety clinic. Measures of difficulties in ER, AS, and disorder specific symptoms were administered at baseline, mid, and post-treatment. A composite anxiety score was calculated to measure anxiety disorder symptom severity across anxiety-related diagnoses.

RESULTS

Individual mediation models revealed that both AS and ER significantly mediated the reduction in anxiety-related symptoms over the course of treatment. A multiple mediation model found that ER was the strongest mediator (indirect effect = -1.030, 95% CI = -2.172 to -0.153). Further analyses revealed that the ER subscale of impulse control difficulties (e.g., the tendency to avoid when confronted with a feared stimulus) was the strongest mediator (indirect effect = -0.849, 95% CI = -1.913 to -0.081).

LIMITATIONS

This study relied solely on self-report measures of ER, AS, and anxiety pathology, and did not have a control group.

CONCLUSIONS

These results suggest that improvement in the ability to control impulses may act as a mechanism of anxiety symptom reduction and may be important to target in CBT with naturalistic samples.

Treating a 16 Year Old with a History of Severe Bullying: Supplementing Cognitive Behavioural Therapy with EMDR within the Context of a Case Formulation Approach

This article describes the use of a case formulation approach, integrating evidence-based treatment in the context of individual clinical traits. It focuses on the supplementation of cognitive behavioural therapy (CBT) with eye movement desensitization and reprocessing (EMDR) in the treatment of a young person, presenting with an initial diagnosis of obsessive-compulsive disorder (OCD). A case formulation suggested the possibility of a differential diagnosis of Adjustment Disorder, indicating the usefulness of the addition of EMDR sessions to process memories of severe bullying. Previous studies promote the idea of using EMDR in cases that do not meet the threshold for Post-Traumatic Stress Disorder (PTSD), in order to reduce the presentation of anxiety. Earlier research suggests that each of these models has specific strengths and attributes in the treatment of mental health difficulties and, whilst based within the context of a well-established case conceptualisation, can be effectively integrated.
