We conducted a randomized, double-blind placebo-controlled trial to examine the efficacy of an attention training procedure in reducing symptoms of social anxiety in forty-four individuals diagnosed with Generalized Social Phobia (GSP). Attention training comprised a probe detection task where pictures of faces with either a threatening or neutral emotional expression cued different locations on the computer screen. In the Attention Modification Program (AMP), participants responded to a probe that always followed neutral faces when paired with a threatening face, thereby directing attention away from threat. In the Attention Control Condition (ACC), the probe appeared with equal frequency in the position of the threat and neutral faces. Results revealed that the AMP facilitated attention disengagement from threat from pre- to post-assessment, and reduced clinician- and self-reported symptoms of social anxiety relative to the ACC. Participants no longer meeting DSM-IV criteria for GSP at post-assessment were 50% in the AMP and 14% in the ACC. Symptom reduction in the AMP group was maintained during four-month follow-up assessment. These results suggest that computerized attention training procedures may be beneficial for treating social phobia.
Our findings would seem to encourage the use of individual-level approaches to connectivity analyses to better delineate the cortical and subcortical networks underlying symptom severity and improvement at the dimensional level in OCD patients.
Background
Intensive residential treatment (IRT) is effective for severe, treatment-resistant obsessive-compulsive disorder (OCD). We sought to characterize predictors and course of response to IRT.
Methods
Admission, monthly, and discharge data were collected on individuals receiving IRT. We examined the association between baseline characteristics and percent change in OCD symptoms as measured by the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS) using linear regression. We compared baseline characteristics of IRT responders (≥35% reduction in Y-BOCS) versus non-responders, and of patients who did versus those who did not achieve wellness (Y-BOCS ≤12) using non-parametric tests. To examine the course of OCD severity over time, we used linear mixed-effects models with randomly varying intercepts and slopes.
Results
We evaluated 281 individuals admitted to an IRT program. Greater baseline Y-BOCS scores were associated with a significantly greater percent reduction in Y-BOCS scores (β = −1.49 ([95% confidence interval: −2.06 to −0.93]; P<.001). IRT responders showed significantly greater baseline Y-BOCS scores than non-responders (mean (SD) 28 (5.2) vs. 25.6 (5.8); P=.003) and lower past-year alcohol use scores than non-responders (1.4 (1.9) vs. 2.1 (2.2); P=.01). Participants who achieved wellness displayed lower hoarding factor scores than those who did not (5 (4.6) vs. 9.53 (6.3); P=.03). OCD symptoms declined rapidly over the first month but more slowly over the remaining two months.
Conclusions
Higher baseline OCD severity, lower past-year alcohol use, and fewer hoarding symptoms predicted better response to IRT. IRT yielded an initial rapid reduction in OCD symptoms, followed by a slower decline after the first month.
Willingness to fully experience unpleasant and unwanted thoughts, emotions, and bodily sensations during exposures appears to be a marker of successful exposure therapy in adults with OCD. Future research should examine how willingness may enhance extinction learning during ERP.
Obsessive-compulsive disorder (OCD) is a heritable disorder, but no
definitive, replicated OCD susceptibility loci have yet been identified by any
genome-wide association study (GWAS). Here, we report results from a GWAS in the
largest OCD case-control sample (N = 14,140 OCD cases and N = 562,117 controls)
to date. We explored the genetic architecture of OCD, including its genetic
relationships to other psychiatric and non-psychiatric phenotypes. In the GWAS
analysis, we identified one SNP associated with OCD at a genome-wide significant
level. Subsequent gene-based analyses identified additional two genes as
potentially implicated in OCD pathogenesis. All SNPs combined explained 16% of
the heritability of OCD. We show sub-stantial positive genetic correlations
between OCD and a range of psychiatric disorders, including anxiety disorders,
anorexia nervosa, and major depression. We thus for the first time provide
evidence of a genome-wide locus implicated in OCD and strengthen previous
literature suggesting a polygenic nature of this disorder.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
