Mindfulness-based stress reduction program in coronary heart disease: A randomized control trial.

BACKGROUND Psychological risk factors such as anxiety and depression have been associated with coronary heart disease (CHD). Stress can have an impact on the risk factors for the disease, such as high blood pressure (BP), physical inactivity and being overweight. AIMS Examine the effect of the Mindfulness-Based Stress Reduction (MBSR) program on symptoms of anxiety and depression, perceived stress, BP and body mass index (BMI) in patients with CHD. SETTINGS AND DESIGN Intervention was carried out at an Outpatient clinic. Parallel group - MBSR group; and treatment-as-usual group (TAU) - randomized control design with pre- (baseline), post-intervention and follow-up assessments was adopted. MATERIALS AND METHODS Thirty male patients, age range (30-65 years) with CHD were randomly allocated to either group. The therapeutic program comprised of eight weekly sessions of structured MBSR intervention for the MBSR group and one health education session for the TAU group. Regular medical intervention and monthly consultations with the cardiologist were consistent for both groups. The main outcome measures were: Hospital Anxiety and Depression Scale, Perceived Stress Scale (perceived stress), BP and BMI. STATISTICAL ANALYSIS Independent sample t-tests, chi square test and paired sample t-test were used. RESULTS All patients completed intervention in the MBSR group. Significant reduction was observed in symptoms of anxiety and depression, perceived stress, BP and BMI in patients of the MBSR group after the completion of intervention assessment. At 3-month follow-up, therapeutic gains were maintained in patients of the MBSR group. CONCLUSION The MBSR program is effective in reducing symptoms of anxiety and depression, perceived stress, BP and BMI in patients with CHD.

Feasibility, Safety, and Efficacy of the Combination of D -Serine and Computerized Cognitive Retraining in Schizophrenia: An International Collaborative Pilot Study

The combination of pharmacotherapy and cognitive retraining (CRT) for the cognitive deficits of schizophrenia may be more efficacious than either approach alone, but this has not yet been tested. This study evaluated the feasibility, safety, tolerability, and efficacy of 12 weeks of D-serine, combined with CRT in the treatment of cognitive deficits in schizophrenia at two academic sites in parallel, in India and the United States. In a randomized, partial double-blind, placebo-controlled, parallel-group design, 104 schizophrenia subjects (US site=22, Indian site=82) were randomized to: (1) D-serine (30 mg/kg)+CRT (5 h/week), (2) D-serine+control CRT, (3) CRT+placebo D-serine, and (4) placebo+control CRT. Completion rates were 84 and 100% in the Indian and US samples, respectively. On various outcome measures of safety and tolerability, the interventions were well tolerated. D-Serine and CRT did not show any significant effect on the Global Cognitive Index, although both interventions showed differential site effects on individual test performance. CRT resulted in a significant improvement in Verbal Working Memory, and a trend toward improvement in Attention/Vigilance. This is the first study to demonstrating the feasibility, safety, and tolerability of combination pharmacotherapy and CRT in a multicenter international clinical trial. These preliminary findings provide support for future studies using higher doses of D-serine that have been shown to be efficacious or other pharmacotherapies, along with the newer cognitive remediation strategies that are individualized and that target basic information processing.

Behavioral interventions for insomnia: Theory and practice.

Insomnia is a general clinical term that refers to a difficulty in initiating or maintaining sleep. Insomnia is widely prevalent in the general population, especially in the elderly and in those with medical and psychiatric disorders. Hypnotic drug treatments of insomnia are effective but are associated with potential disadvantages. This article presents an overview of behavioral interventions for insomnia. Behavioral interventions for insomnia include relaxation training, stimulus control therapy, sleep restriction therapy, sleep hygiene, paradoxical intention therapy, cognitive restructuring, and other approaches. These are briefly explained. Research indicates that behavioral interventions are efficacious, effective, and likely cost-effective treatments for insomnia that yield reliable, robust, and long-term benefits in adults of all ages. Detailed guidance is provided for the practical management of patients with insomnia.

Cognitive behavior therapy for Stuttering: A case series

The present investigation was aimed at studying the efficacy of cognitive behavior therapy (CBT) in reducing the symptoms of stuttering and dysfunctional cognitions and in enhancing assertiveness and quality of life in clients with stuttering. Five clients with stuttering who met the inclusion criteria (male clients with diagnosis of stuttering) and exclusion criteria (clients with brian damage), substance abuse or mental retardation were enrolled for the study. A single-case design was adopted. The pre-, mid- and post-assessment were carried out using Stuttering Severity Scale (SSI), Perception of Stuttering Inventory (PSI), Becks Anxiety Inventory (BAI), Dysfunctional Attitude (DAS), Fear of Negative Evaluation (FNE), Assertiveness Scale (AS), Rosenbergs Self-Esteem Scale (RSES), and World Health Organization - Quality of Life Scale (WHO-QOL). Five clients received cognitive behavioral intervention comprising of psycho-education, relaxation, deep breathing, humming, prolongation, cognitive restructuring, problem-solving strategies and assertiveness. At post-treatment assessment, there was improvement. The findings of the study are discussed in the light of available research work, implications, limitations of the study and suggestions for future research.

Behavioural and psychological management of somatic symptom disorders: an overview.

Abstract The number of patients who seek help at primary and secondary care for somatic symptoms which cannot be explained by any known medical condition is enormous. It has been proposed to rename ‘somatoform disorders’ in DSM-IV as ‘somatic symptom disorders’ in DSM-5. This is supposed to include disorders such as somatization disorder, hypochondriasis, undifferentiated somatoform disorder, pain disorder and factitious disorder. The reason for the renaming and grouping is that all these disorders involve presentation of physical symptoms and/or concern about medical illness. In the literature, there is considerable variation adopted with respect to diagnosis and in the approaches adopted for intervention. However, the common feature of these disorders is the chronicity, social dysfunction, occupational difficulties and the increased healthcare use and high level of dissatisfaction for both the clinician and the patient. A number of behavioural and psychological interventions for somatic symptoms have been carried out at primary, secondary and tertiary care settings and recently there have been more attempts to involve the primary care physicians in the psychological interventions. This review aims at giving an overview of the components of the behavioural and other psychological interventions available for addressing medically unexplained somatic symptoms and to present their efficacy.

Development of Cognitive-Behavioral Therapy Intervention for Patients with Dhat Syndrome

Dhat syndrome is a culture-bound syndrome prevalent in the natives of the Indian subcontinent characterized by excessive concern about harmful consequences of loss of semen (ICD-10). Treatment offered to the patients suffering from it continues to be esoteric, unstructured and without standardization. The present study aimed to develop and examine the feasibility of Cognitive – Behavior Therapy module for patients with Dhat syndrome. A draft module was developed based on existing theoretical knowledge and suggestions from five mental health professionals. This module was then applied on five patients with Dhat syndrome to assess and judge the suitability of the module. The pre and post-assessments were carried out using Sexual Knowledge and Attitude Questionnaire - II, Hamilton Depression Rating Scale, The Cognitive-Somatic Anxiety Scale, Screener for Somatoform Disorder, International Index for Erectile Function, Clinical Global Impressions, The World Health Organization Quality of Life Assessment - BREF. Experiences and insights gained from each patient were used to refine the module before applying on the next patient. The final module consisted of the following components was developed: Basic sex education, cognitive restructuring, relaxation training, imaginal desensitization, masturbatory training as homework and Kegels exercises and ‘start-stop technique’ and ‘squeeze technique’ for sexual dysfunctions. Results of the study reveal that it is feasible to carry out the CBT module in clinical settings. Number of sessions ranged from 11 to 16 sessions. The duration of the session was 45 minutes on the average. Findings of the present study revealed improvement in sexual knowledge, anxiety, depressive and somatic symptoms. Implications and limitations of the study are highlighted and suggestions for future research offered.

Mindfulness-based cognitive behavior therapy in patients with anxiety disorders: A case series

The present study is aimed at evaluating the effectiveness of a Mindfulness-Based Cognitive Behavior Therapy (MBCBT) for reducing cognitive and somatic anxiety and modifying dysfunctional cognitions in patients with anxiety disorders. A single case design with pre- and post-assessment was adopted. Four patients meeting the specified inclusion and exclusion criteria were recruited for the study. Three patients received a primary diagnosis of generalized anxiety disorder (GAD), while the fourth patient was diagnosed with Panic Disorder. Patients were assessed on the Cognitive and Somatic Anxiety Questionnaire (CSAQ), Penn State Worry Questionnaire (PSWQ), Hamiltons Anxiety Inventory (HAM-A), and Dysfunctional Attitudes Scale. The therapeutic program consisted of education regarding nature of anxiety, training in different versions of mindfulness meditation, cognitive restructuring, and strategies to handle worry, such as, worry postponement, worry exposure, and problem solving. A total of 23 sessions over four to six weeks were conducted for each patient. The findings of the study are discussed in light of the available research, and implications and limitations are highlighted along with suggestions for future research.

Quality of life in anxiety disorders: Its relation to work and social functioning and dysfunctional cognitions: An exploratory study from India

The aim of the study was to examine quality of life, functioning, disability, work and social adjustment, depression, anxiety and dysfunctional cognitions in patients with anxiety disorders. One hundred patients with anxiety disorders and 98 non-clinical participants were recruited for the study. A cross sectional design was adopted. The participants were assessed on the WHOQoL-BREF, Global Assessment of Functioning (GAF), Sheehan Disability Scale (SDS), the Work and Social Adjustment Scale (WSAS) and Dysfunctional Attitudes Scale (DAS). Data was analyzed using descriptive statistics, Mann-Whitney test, Spearmans Rho and regression analysis. Patients with anxiety disorders reported significantly lower quality of life than the community sample (df=98, p<.001). A shorter duration of illness was associated with lower quality of life. QoL was significantly correlated with severity of anxiety, depression and stress as well as with measures of disability and adjustment. Partial correlations indicated that depression did not significantly impact the relationship between work and social adjustment and QoL. Work and social adjustment, depression and dysfunctional cognitions emerged as significant predictors of QoL. The findings of the study are discussed in the light of existing research and the implications for future interventions are highlighted.

Efficacy of mindfulness-integrated cognitive behavior therapy in patients with predominant obsessions

Background: Cognitive behavior therapy (CBT) involving exposure and response prevention is the gold standard psychotherapeutic intervention for obsessive-compulsive disorder (OCD). However, applying traditional CBT techniques to treat patients with predominant obsessions (POs) without covert compulsions is fraught with problems because of inaccessibility of mental compulsions. In this context, we examined the efficacy of mindfulness-integrated CBT (MICBT) in patients with POs without prominent overt compulsions. Materials and Methods: Twenty-seven patients with Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition diagnosis of OCD were recruited from the specialty OCD clinic and the behavior therapy services of a tertiary care psychiatric hospital over 14 months. Patients had few or no overt compulsions and were free of medication or on a stable medication regimen for at least 2 months prior to baseline assessment. All patients received 12–16 sessions of MICBT on an outpatient basis. An independent rater (psychiatrist) administered the Yale–Brown Obsessive-Compulsive Scale (YBOCS) and the Clinical Global Impression Scale at baseline, mid- and post-treatment, and at 3-month follow-up. Results: Of the 27 patients, 18 (67%) achieved remission (55% reduction in the YBOCS severity score) at 3-month follow-up. The average mean percentage reduction of obsessive severity at postintervention and 3-month follow-up was 56 (standard deviation [SD] = 23) and 63 (SD = 21), respectively. Conclusions: Our study demonstrates that MICBT is efficacious in treating patients with POs without prominent overt compulsions. The results of this open-label study are encouraging and suggest that a larger randomized controlled trial examining the effects of MICBT may now be warranted.

Symptom Dimensions in Obsessive-Compulsive Disorder and Obsessive Beliefs

Background: Obsessive-compulsive disorder (OCD) is a heterogeneous condition with a few major symptom dimensions. These symptom dimensions are thought to have unique clinical and neurobiological correlates. There seems to be a specific relation between OCD symptom dimensions and obsessive beliefs, but the findings are not consistent across studies. There is also a paucity of literature from culturally diverse settings. One of the reasons for the varied findings could be due to the method employed in measuring OCD symptoms. Materials and Methods: In this study, we examined the relation between symptom dimensions and obsessive beliefs using the Dimensional Yale-Brown Obsessive-Compulsive Scale and the Obsessive Beliefs Questionnaire respectively in 75 patients with Diagnostic and Statistical Manual of Mental Disorders-Fourth Edition OCD. Results: Perfectionism predicted both aggressive and symmetry dimensions whereas responsibility beliefs predicted sexual and religious dimensions. Conclusions: The findings suggest that certain obsessive beliefs predicted certain OCD symptom dimensions, but results are not entirely consistent with the published literature suggesting the possibility of cross-cultural variations. That the symptom dimensions have unique belief domains support the argument that symptom dimensions could be targeted to reduce the heterogeneity in etiological and treatment studies of OCD. Therapeutic interventions may have to aim at modifying unique belief domains underlying certain symptom dimensions rather than having generic cognitive-behavioral strategies.
