Yoga for generalized anxiety disorder: design of a randomized controlled clinical trial.

Generalized anxiety disorder (GAD) is a common disorder associated with significant distress and interference. Although cognitive behavioral therapy (CBT) has been shown to be the most effective form of psychotherapy, few patients receive or have access to this intervention. Yoga therapy offers another promising, yet under-researched, intervention that is gaining increasing popularity in the general public, as an anxiety reduction intervention. The purpose of this innovative clinical trial protocol is to investigate the efficacy of a Kundalini Yoga intervention, relative to CBT and a control condition. Kundalini yoga and CBT are compared with each other in a noninferiority test and both treatments are compared to stress education training, an attention control intervention, in superiority tests. The sample will consist of 230 individuals with a primary DSM-5 diagnosis of GAD. This randomized controlled trial will compare yoga (N=95) to both CBT for GAD (N=95) and stress education (N=40), a commonly used control condition. All three treatments will be administered by two instructors in a group format over 12 weekly sessions with four to six patients per group. Groups will be randomized using permuted block randomization, which will be stratified by site. Treatment outcome will be evaluated bi-weekly and at 6month follow-up. Furthermore, potential mediators of treatment outcome will be investigated. Given the individual and economic burden associated with GAD, identifying accessible alternative behavioral treatments will have substantive public health implications.R01 AT007257 - NCCIH NIH HHS; R01 AT007258 - NCCIH NIH HH

Predictors of Treatment Outcome in Modular Cognitive Therapy for Obsessive-Compulsive Disorder

Background: The present study sought to identify predictors of outcome for a comprehensive cognitive therapy (CT) developed for patients with obsessive-compulsive disorder (OCD). Methods: Treatment was delivered over 22 sessions and included standard CT methods, as well as specific strategies designed for subtypes of OCD including religious, sexual, and other obsessions. This study of 39 participants assigned to CT examined predictors of outcomes assessed on the Yale-Brown Obsessive Compulsive Scale. A variety of baseline symptom variables were examined as well as treatment expectancy and motivation. Results: Findings indicated that participants who perceived themselves as having more severe OCD at baseline remained in treatment but more severe symptoms were marginally associated with worse outcome for those who completed therapy. Depressed and anxious mood did not predict post-test outcome, but more Axis I comorbid diagnoses (mainly major depression and anxiety disorders), predicted more improvement, as did the presence of sexual (but not religious) OCD symptoms, and stronger motivation (but not expectancy). A small rebound in OCD symptoms at 1-year follow-up was significantly predicted by higher scores on personality traits, especially for schizotypal (but not obsessive-compulsive personality) traits. Conclusions: Longer treatment may be needed for those with more severe symptoms at the outset. CT may have positive effects not only on OCD symptoms but also on comorbid depressive and anxious disorders and associated underlying core beliefs. Findings are discussed in light of study limitations and research on other predictors

The epidemiology of the proposed DSM-5 hoarding disorder: exploration of the acquisition specifier, associated features, and distress

Compulsive hoarding, characterized by the acquisition of and failure to discard a large number of possessions, is increasingly recognized as a significant public health burden. Many facets of the phenomenology, including an understanding of the population prevalence and associated features, are not yet fully understood. There is growing evidence that hoarding may warrant its own diagnosis in DSM-5, and it is therefore imperative to investigate the proposed cardinal symptoms along with correlated features that may be diagnostically relevant. The present investigation examined the point prevalence of hoarding disorder in a nationally representative sample from the German population (N = 2,512). The hoarding definition considered in this study was derived from the Hoarding Rating Scale (HRS) and informed by 3 of the proposed DSM-5 criteria. Several hypothesized core components of hoarding disorder were also assessed using questions from the HRS and the UCLA Hoarding Severity Scale, including types of acquisition, perfectionism, indecision, procrastination, distress, and impairment. Data were collected from May 16, 2009, to June 19, 2009. Analyses revealed a current population estimate of 5.8%. Hoarding prevalence did not differ between men and women. Hoarders were significantly more likely to buy items, acquire free things, and steal items they did not need, compared to nonhoarders (P < .001). Perfectionism, indecision, and procrastination were all uniquely and significantly associated with hoarding status (P < .001). Relationships between the proposed core features and distress/impairment are also detailed. The current investigation identified the proposed hoarding disorder as a highly prevalent syndrome; however, it should be noted that we were not able to fully ascertain the DSM-5 criteria and that the current estimate may be higher than the actual population rate. Future research on the diagnostic criteria and associated features will be necessary to help clarify etiologic underpinnings, treatment efforts, and diagnostic nosology

Binge/purge thoughts in nonsuicidal self-injurious adolescents: An ecological momentary analysis

Objective Adolescents who self-injure often engage in bingeing/purging (BP). Ecological momentary assessment (EMA) has potential to offer insight into the relationship between self-injury and BP. The aims of this study were to examine the frequency and context of BP using EMA in a sample of nonsuicidal self-injurious (NSSI) adolescents. Method Thirty adolescents with a history of NSSI responded to questions regarding self-destructive thoughts/behaviors using a palm-pilot device. Descriptive analyses compared thought/behavior contexts during reports of BP and NSSI thoughts/behaviors (occurring together vs. individually). Results BP thoughts were present in 22 (73%) participants, occurring on 32% of the person-days recorded; 59% of these participants actually engaged in BP behavior. Seventy-nine percent of BP thoughts co-occurred with other self-destructive thoughts. Adolescents were more often with friends/peers than alone or with family when having BP thoughts. Worry and pressure precipitated both BP and NSSI thoughts, but perceived criticism and feelings of rejection/hurt were associated more often with BP thoughts than with NSSI thoughts. Discussion BP thoughts and behaviors were common in this sample, often occurring with other self-destructive thoughts. Future EMA research is needed to address the function of BP symptoms, the contextual variables that increase risk for BP thoughts, and the factors that predict the transition of thoughts into behaviors in adolescents with and without self-injury.Psycholog

Predictors of long-term recovery in anorexia nervosa and bulimia nervosa: Data from a 22-year longitudinal study

Objective The objective of this study was to investigate predictors of long-term recovery from eating disorders 22 years after entry into a longitudinal study. Method One hundred and seventy-six of the 228 surviving participants (77.2%) were re-interviewed 20-25 years after study entry using the Longitudinal Interval Follow-up Evaluation to assess ED recovery. The sample consisted of 100 women diagnosed with anorexia nervosa (AN) and 76 with bulimia nervosa (BN) at study entry. Results A comorbid diagnosis of major depression at the start of the study strongly predicted having a diagnosis of AN-Restricting type at the 22-year assessment. A higher body mass index (BMI) at study intake decreased the odds of being d

Cardiovascular adverse events during adjuvant endocrine therapy for early breast cancer using letrozole or tamoxifen: safety analysis of BIG 1-98 trial

PURPOSE: Previous analyses of adjuvant studies of aromatase inhibitors versus tamoxifen, including the Breast International Group (BIG) 1-98 study, have suggested a small numerical excess of cardiac adverse events (AEs) on aromatase inhibitors, a reduction in the incidence of hypercholesterolemia on tamoxifen, and significantly higher incidence of thromboembolic AEs on tamoxifen. The purpose of the present study is to provide detailed updated information on these AEs in BIG 1-98. PATIENTS AND METHODS: Eight thousand twenty-eight postmenopausal women with receptor-positive early breast cancer were randomly assigned (double-blind) between March 1998 and May 2003 to receive 5 years of adjuvant endocrine therapy with letrozole, tamoxifen, or a sequence of these agents. Seven thousand nine hundred sixty-three patients who actually received therapy are included in this safety analysis, which focuses on cardiovascular events. AE recording ceased 30 days after therapy completion (or after switch on the sequential arms). RESULTS: Baseline comorbidities were balanced. At a median follow-up time of 30.1 months, we observed similar overall incidence of cardiac AEs (letrozole, 4.8%; tamoxifen, 4.7%), more grade 3 to 5 cardiac AEs on letrozole (letrozole, 2.4%; tamoxifen, 1.4%; P = .001)--an excess only partially attributable to prior hypercholesterolemia--and more overall (tamoxifen, 3.9%; letrozole, 1.7%; P < .001) and grade 3 to 5 thromboembolic AEs on tamoxifen (tamoxifen, 2.3%; letrozole, 0.9%; P < .001). There was no significant difference between tamoxifen and letrozole in incidence of hypertension or cerebrovascular events. CONCLUSION: The present safety analysis, limited to cardiovascular AEs in BIG 1-98, documents a low overall incidence of cardiovascular AEs, which differed between treatment arms
