Prevention of implantable defibrillator shocks by cognitive behavioral therapy: a pilot trial.

BACKGROUND: Although psychological stress is known to favor ventricular arrhythmic events, there is no evidence that stress management intervention decreases ventricular electrical instability in implantable cardioverter-defibrillator (ICD) patients. The aim of the study was to determine whether cognitive behavioral therapy (CBT) results in a decrease of arrhythmic events requiring ICD intervention through an improvement in sympathovagal balance. METHODS: Of 253 consecutive ICD patients (age 59 +/- 10 years, 64 men), 70 were randomly assigned to CBT (n = 35) or conventional medical care (n = 35). Measures of heart rate variability, psychological well-being, and quality of life were assessed at baseline, 3 months, and 1 year. The primary outcome was appropriate ICD shock. RESULTS: Although, it was not statistically different, the number of patients requiring shocks was less in the CBT group than in the conventional treatment group. At 3 months, among patients without antiarrhythmic drugs, none of the subjects in the CBT group had experienced arrhythmic events requiring ICD intervention, as compared with 4 in the control group (P < .05). At 12 months, there was no difference in the number of arrhythmic events requiring therapy between the CBT group versus the control group. Among heart rate variability indexes, daytime pNN 50 and nocturnal SDNN improved significantly in the CBT group, as compared with the control group. CONCLUSIONS: By decreasing anxiety and possibly improving sympathovagal balance, cognitive behavior therapy may decrease the propensity for ventricular arrhythmias in ICD patients. However, these effects appear to be limited over time.

Combining Pharmacotherapy with cognitive-behavioral interventions for obsessive-compulsive disorder.

This paper reviews the evidence-based literature concerning the efficacy and effectiveness of cognitive behavior therapy (CBT), drug treatment and their combination for obsessive compulsive disorder (OCD). After a brief outline of the seminal studies, the state of the art is presented with reference to the consensual recommendations proposed in the last 10 years. Management of OCD rests on potent selective serotonin reuptake inhibitors and CBT, used separately, sequentially, or concurrently. A hierarchical model for clinical decision-making is reported. With greater severity of OCD, it is recommended to add medications. However, the response rate is still too low in many patients, and some patients remain refractory to any kind of treatment. This stresses the importance of joint efforts of psychological and biological teams to develop new treatments.

Recent developments in research and treatment for social phobia (social anxiety disorder).

PURPOSE OF REVIEW: This review covers three themes of research that brought fresh data useful for clinical practice in a handicapping anxiety disorder: social phobia. Recent findings deriving from basic biological research, new forms of psychological therapies, and recent psychopharmacology controlled trials are reviewed. RECENT FINDINGS: The basic neuroimaging research suggests that greater activation of the amygdala to novel versus familiar faces may be an underlying trait marker for social phobia. Social phobia may represent a phenotype that expresses a genetically driven trait of social withdrawal, which may be related to infantile inhibited temperament (Kagan's syndrome). The development of virtual reality therapy as therapeutic tool for social phobia appeared promising in one controlled, but not randomized, study. A controlled study suggests that social phobias in children can be effectively treated with cognitive behavioural therapy. This represents an extension of the work done with adults. Venlafaxine appears an effective short-term treatment for social anxiety disorder in two controlled studies. A new compound, pregabalin, appeared clearly effective in a positive controlled study. This trial marks the advent of a new pharmacological lineage for social phobia. Both venlafaxine and pregabalin, however, have been studied in short-term studies. Longer follow-up and relapse prevention studies are warranted. SUMMARY: Neuroimaging research points to a temperamental basis for social phobia. Virtual reality therapy is an emerging tool to carry out exposure treatment. Group cognitive behavioural therapy can be extended successfully to children. Venlafaxine and pregabalin have a proven short-term effectiveness in social phobia.

The validation of the Posttraumatic Stress Disorder Checklist Scale in posttraumatic stress disorder and nonclinical subjects.

BACKGROUND: The Posttraumatic Stress Disorder Checklist Scale (PCLS) is a short self-report inventory for assessing the 3 main syndromes of Posttraumatic Stress Disorder (PTSD). The aim of this study was the validation of the French version of the PCLS in PTSD subjects and nonclinical subjects. METHODS: One-hundred and thirteen outpatients suffering from PTSD according to DSM-IV were administered the PCLS. The patients' scores on the PCLS were then compared to those of 31 nonclinical control subjects. Thirty-five of the patients were administered the PCLS twice over an interval of 1-2 weeks and also completed questionnaires measuring depression, phobia and anxiety. RESULTS: The patients' total score and subscores on the PCLS were found to be significantly higher than those of control subjects. The cutoff score of 44 on the French version PCLS distinguishes well between the PTSD group and control group with a high diagnostic efficacy (0.94). Factor analysis revealed 3 main factors corresponding to the reexperiencing, numbing and hyperarousal syndromes. The PCLS showed satisfactory test-retest reliability and internal consistency. CONCLUSIONS: The PCLS is therefore a valid and effective measurement of PTSD. It may be a useful tool for screening and assessing PTSD in psychiatric as well as in primary-care settings.
