Does cognitive behavioral therapy alter mental defeat and cognitive flexibility in patients with panic disorder?

OBJECTIVE: Mental defeat and cognitive flexibility have been studied as explanatory factors for depression and posttraumatic stress disorder. This study examined mental defeat and cognitive flexibility scores in patients with panic disorder (PD) before and after cognitive behavioral therapy (CBT), and compared them to those of a gender- and age-matched healthy control group. RESULTS: Patients with PD (n = 15) received 16 weekly individual CBT sessions, and the control group (n = 35) received no treatment. Patients completed the Mental Defeat Scale and the Cognitive Flexibility Scale before the intervention, following eight CBT sessions, and following 16 CBT sessions, while the control group did so only prior to receiving CBT (baseline). The patients' pre-CBT Mental Defeat and Cognitive Flexibility Scale scores were significantly higher on the Mental Defeat Scale and lower on the Cognitive Flexibility Scale than those of the control group participants were. In addition, the average Mental Defeat Scale scores of the patients decreased significantly, from 22.2 to 12.4, while their average Cognitive Flexibility Scale scores increased significantly, from 42.8 to 49.5. These results suggest that CBT can reduce mental defeat and increase cognitive flexibility in patients with PD Trial registration The study was registered retrospectively in the national UMIN Clinical Trials Registry on June 10, 2016 (registration ID: UMIN000022693).

A feasibility study of the clinical effectiveness and cost-effectiveness of individual cognitive behavioral therapy for panic disorder in a Japanese clinical setting: an uncontrolled pilot study.

BACKGROUND: In Japan, cognitive behavioral therapy (CBT) for panic disorder (PD) is not well established. Therefore, a feasibility study of the clinical effectiveness and cost-effectiveness of CBT for PD in a Japanese clinical setting is urgently required. This was a pilot uncontrolled trial and the intervention consisted of a 16-week CBT program. The primary outcome was Panic Disorder Severity Scale (PDSS) scores. Quality of life was assessed using the EuroQol's EQ-5D questionnaire. Assessments were conducted at baseline, 8 weeks, and at the end of the study. Fifteen subjects completed outcome measures at all assessment points. RESULTS: At post-CBT, the mean reduction in PDSS scores from baseline was -6.6 (95 % CI 3.80 to -9.40, p < 0.001) with a Cohen's d = 1.77 (95 % CI 0.88-2.55). Ten (66.7 %) participants achieved a 40 % or greater reduction in PDSS. By calculating areas under the curve for EQ-5D index changes, we estimated that patients gained a minimum of 0.102 QALYs per 1 year due to the CBT. CONCLUSIONS: This study demonstrated that individual CBT for PD may be useful in Japanese clinical settings but further randomized control trials are needed. TRIAL REGISTRATION: UMIN-CTR UMIN000022693 (retrospectively registered).

Differential reactivity of attention biases in patients with social anxiety disorder

Information-processing biases based on cognitive and cognitive behavioral models have been reported in social anxiety disorder (SAD). One such bias is the attention bias, or selectively attending to threat stimuli. This bias has been associated in anxiety with maintenance and worsening of SAD symptoms. The objective of the present study was to examine, compare, and clarify differences in attention biases to language stimuli between SAD patients and healthy people. Results indicated, no differences between the two groups, but differences were seen in the attention bias score among SAD patients. This suggests that there is an increased threat effect among SAD patients triggered by their attention bias toward social threat stimuli (AU)
