ABSTRACT
Objective@#Acceptance and commitment therapy (ACT) has been recently introduced for treating obsessive-compulsive disorder (OCD). Although there are data supporting the efficacy of ACT, only few studies have investigated the effectiveness of ACT against any obsessivecompulsive (OC) symptom dimension or a specific dimension alone. @*Methods@#In total, 64 patients with OCD received an 8-session ACT group program. All measures were evaluated before and after treatment. The Dimensional Obsessive-Compulsive Scale was used to assess OCD severity across the four empirically supported symptom dimensions (i.e., contamination, responsibility for harm, unacceptable thoughts, and symmetry). ACT processes were evaluated using the Acceptance and Action Questionnaire-II (AAQ-II), Acceptance and Action Questionnaire for Obsessions and Compulsions (AAQOC), and Cognitive Fusion Questionnaire. @*Results@#After an 8-week program, there were significant reductions in all four OC symptom dimensions after ACT. The unacceptable thoughts and contamination domains had medium effect size. The responsibility for harm and symmetry dimensions had small effect size. The unacceptable thoughts dimension was significantly correlated with all ACT process measures. The symmetry dimension was significantly correlated with AAQ-OC and AAQ-II scores while the responsibility for harm dimension was correlated with AAQ-II alone. However, the contamination dimension was not associated with any process measures. @*Conclusion@#ACT may be effective for managing all four symptom dimensions with small to moderate effect size. Moreover, depending on the symptom dimension, there may be different relationship patterns between symptom reduction and changes in ACT processes.
ABSTRACT
Objectives@#：Acceptance Commitment Therapy (ACT) was recently introduced to the treatment of the obsessivecompulsive disorder (OCD). Major core components of ACT can be effectively applied to OCD treatment. Cognitive defusion can make to reduce anxiety related to obsessional thought by observing and flowing the thoughts in a nonjudgemental manner. Value-based commitment can be helpful to confront situations rather than experiential avoidance. Although several studies verified the effectiveness of ACT treatment on OCD, there is a lack of study in Korea. @*Methods@#：Forty-four patients with OCD were randomly assigned to treatment or control groups (22 patients per group). An eight-session, 90-minute ACT program was developed and conducted for 8 weeks for the treatment group. Symptoms were measured before and after 8 weeks, using Yale-Brown Obsessive-Compulsive Scale (Y-BOCS), Obsessive-Compulsive Inventory (OCI), Beck Depression Inventory (BDI), and Cognitive Fusion Questionnaire (CFQ). @*Results@#：After eight-week program, the treatment group showed greater reductions in cognitive fusion score (p= 0.001) as well as obsessive-compulsive symptoms measured by both Y-BOCS and OCI (ps<0.001) compared to the control group. Moreover, changes in cognitive fusion score were significantly correlated with changes of Y-BOCS, OCI, and BDI scores (all ps<0.05). @*Conclusions@#：To the best of our knowledge, our study is the first report to verify the effectiveness of a group based ACT program on OCD in Korea. Our ACT program was effective to reduce symptoms of OCD and related cognitive fusion. Future study with longitudinal design and large sample sizes are needed to investigate confirmatory and longterm effects of our ACT program for OCD.
ABSTRACT
Background@#Dietary intake of n-3 fatty acids have been suggested for their protective role against cardiovascular disease. However, findings from recent studies have been inconsistent. Thus, we investigated the association between dietary intake of n-3 fatty acids and the 10-year risk of cardiovascular disease (CVD). @*Methods@#We analyzed data from 17,390 adults who were aged 30–64 years and free of CVD using the Korea National Health and Nutrition Examination Survey, 2012–2016. Dietary intake of n-3 fatty acids was calculated by using food-frequency questionnaire, and the 10 year risk of CVD was calculated by Framingham general cardiovascular disease risk score (2008) model. We analyzed the odds ratios (ORs) and 95% confidence intervals (CIs) from logistic regression to evaluate the association between dietary intake of n-3 fatty acids and the 10-year risk of CVD. @*Results@#Logistic regression anlaysis showed that dietary intake of n-3 fatty acids was not significantly associated with the 10-year risk of CVD, after adjusting for confounders (OR=0.91; 95% CI, 0.77–1.07). But higher dietary intake of n-3 fatty acids was associated with reduced the 10-year risk of CVD for the female (OR=0.74; 95% CI, 0.58–0.95). @*Conclusion@#Our research indicated no significant association between dietary intake of n-3 fatty acids and the 10-year risk of CVD. But the inverse association was observed in the female.
