Filter by:Investigation is designed to determine whether the gold standard for treating anxious youth is enhanced by teaching parents to become their anxious child's CBT coach. Children (7-17 years old) with either Generalized Anxiety Disorder, Social Phobia, or Separation Anxiety Disorder are treated with a combination of the Coping Cat Program and a parent-training intervention that is designed to teach the child's parents the same cognitive and behavioral skills that the child is learning and how to help their child to complete exposure activities. The research methods are parallel to those used in the CAMS study so that this data can be merged with that data set to evaluate the relative efficacy of the enhanced intervention.
Coming for a cardiac test can be a daunting experience. Despite providing written information sheets for patients, experience in the scanner demonstrates that many patients are ill-prepared when they attend for cardiac computed tomography (CT). Heart rate control is essential for high image quality, as this prolongs cardiac diastole (during which imaging occurs) and results in less motion blur, but this may be challenging to achieve in the context of an anxious patient. In such situations, additional radiation exposure is required to optimise the chances of diagnostic images. Thus, poor patient selection and preparation has been shown to increase the radiation burden to the patient, as well as to increase the rate of non-diagnostic scans, leading to patients needing additional, alternative testing. This can be distressing for patients and increases downstream costs for the hospital. Poor patient awareness is also known to increase the anxiety of attending for a test. Improved patient information and understanding has been shown to improve outcomes in a wide variety of hospital settings. Evidence from cardiac catheterisation angiography suggests that the use of alternative information formats can reduce patient anxiety and improve patient satisfaction, as well as improving their understanding of the technical requirements of a test. The latter may contribute to improved preparation - for example, patients who do not understand the requirements for cardiac CT, particularly the need for a slow heart rate, will often consume caffeine, stop their heart-slowing drugs, or even run or cycle to their appointment. We have agreed a collaboration with Plymouth University to create patient information videos for CT. These will utilise the expertise of media students (their department also runs a commercial arm, due to the quality of their output), in conjunction with the clinical requirements and patient participation groups, to create an accessible, engaging and informative film. We wish to evaluate the impact of this method of conveying information to patients on how well they are prepared to undergo testing. If this concept is successful, it may be of use to patients undergoing a huge range of tests or treatments across specialities. We therefore need to demonstrate the efficacy (or otherwise) of such an intervention.
Research in the last fifteen years suggests that anxious individuals selectively attend towards threatening information. Attention modification interventions for internalizing adults have been developed to target cognition at this basic level; these programs have demonstrated initial efficacy in attention bias and anxiety symptom reduction. To date, there have been minimal published studies of attention modification in youths with clinical levels of anxiety. This study is a large randomized efficacy-effectiveness trial (N = 498) to test the benefit of this low-cost, computerized attention modification intervention (Cognitive Bias Modification (CBM) computer application) for anxiety disorders and symptomatology in youth ages 12 to 17. This trial conducted will compare three intervention arms, all of which include underlying treatment as usual (TAU). The investigators directly test the level of clinical support ("scaffolding") needed to adequately deliver self-administered CBM to anxious youth, a finding that will be key to preparing for future deployment-focused trials. The investigators will compare an attention control version of the CBM program (Arm 1) to two active versions of the CBM intervention that have varying levels of patient clinical support: a self-administered CBM program that participants download and install on their home computers (Self-Administered CBM-only; Arm 2), and the same CBM program paired with an adherence promotion (AP) component delivered via brief telephone calls from study "coaches," including as needed, brief motivational enhancement and/or technical assistance (Self-Administered CBM+AP; Arm 3). The investigators expect that youth receiving CBM and CBM+AP will have improvement in anxiety symptoms and functioning. The investigators will also complete a cost-effectiveness analysis to examine potential costs offset by this intervention.
The aim of this study is to examine if repetitive computerized cognitive training improves working memory in patients who are on sick leave due to complex symptom disorders (chronic pain, chronic fatigue, anxiety, depression and or sleep disorders), and whether effects of cognitive control training transfer to other tasks.
Objective: The overall aim of this protocol is to examine the effect of pharmacological manipulations of affective and cognitive processes on anxiety and task performance. Ultimately, the goal is 1) to provide insight into the relative influence of cognitive and affective states on anxiety, 2) generate theoretical models that can be applied to a better understanding of the interaction between cognition and emotion, 3) develop a better screening approach to candidate anxiolytics, and 4) help formulate novel therapeutic interventions for clinical anxiety. Excessive or inappropriately sustained anxiety and fear lead to the most common group of psychiatric disorders. A number of theoretical models have been proposed to understand the mechanisms engaged in these maladaptive behaviors. Most recent emphasis has focused on the synergistic contribution of cognitive and emotional processes. Our laboratory has been instrumental in delineating aspects of behavioral and neural processes that are associated with fear and anxiety, using psychophysiological and neuroimaging measures of fear and anxiety. Evidence shows that levels of anxiety modulate cognitive performance, such as working memory or perceptual discrimination, and that, conversely, cognitive engagement influences severity of experimentally induced anxiety. The exact contribution of emotional processes vs. cognitive processes to the experience of anxiety is not clear, similarly to the neural mechanisms underlying these interactions. In this protocol, we propose to manipulate pharmacologically separately cognitive and emotional processes to dissociate their contribution to fear/anxiety, while using state-of-the-art measures of anxiety derived from translational work. Indeed, we already developed integrative experimental models of fear and anxiety via the manipulation of predictable and unpredictable shock, respectively. We already employed successfully these models to measure anxiolytic and anxiogenic effects of various compounds such as alprazolam, citalopram, hydrocortisone, and oxytocin in healthy participants. We propose in a first step (step-1) to start with a simple proof-of-concept study, using two pharmacological compounds in a double-blind randomized parallel design, each preferentially acting respectively on the cognitive (methylphenidate) or affective (propranolol) domain, and using a single cognitive process (working memory). In a second step (step-2), we propose to extend this work to the fMRI to examine the cognitive correlates of the effects seen in the step-1 behavioral study, specifically with methylphenidate. Whereas the comparison among three drugs is planned for the electrophysiology study, we plan to study only the drug that improves cognition in the fMRI. The reason we will focus on methylphenidate in step 2 is that our overall goal is to study the effect of improving cognitive functions on anxiety using neuroimaging. To reach this goal, we plan to use different approaches to boost cognitive functions in the coming years, including psychopharmacology, direct current stimulation, mindfulness. Methylphenidate is our first psychopharmacological study towards this objective. Future work will also expand to other compounds and cognitive processes, as well as vary the strategy to induce anxiety. Presently, anxiety will be induced using the threat of shock, while participants perform the task. We will examine in step-1 whether 1) the reduction of induced-anxiety with propranolol improves cognitive performance, and 2) the facilitation of cognitive performance with methylphenidate reduces induced-anxiety. In step-2, we will identify the neural mechanisms underlying the effects of methylphenidate, the drug having beneficial effects on cognitive function. Study population: Medically and psychiatrically healthy adult males and females, aged 18 to 50 years. Design: The study is a double-blind design. For step-1, three groups of healthy participants will come for one experimental session. During this session, they will be asked to perform a working memory task under the threat of shock, i.e., while anticipating unpleasant electric shocks. Each group will receive one drug challenge, either placebo, propranolol (40 g) or methylphenidate (20 mg). For step-2, the study tasks will be conducted in a 3T fMRI scanner. In this step, only methylphenidate and placebo will be compared. Two groups will come for one experimental session, one will receive placebo and the other one will receive methylphenidate (20 mg). In a follow-up study for the step-2 fMRI the two groups will come for one experimental fMRI session one will receive methylphenidate (60 mg). Outcome measures: In step-1, the primary outcome measures are the startle reflex and performance on the working memory task. In step-2, the primary outcome measures are the startle reflex and the cerebral fMRI blood-oxygen-level ...
The study is to explore the effectiveness of omega-3 fatty acids and mindfulness-based stress management program to maintain healthy mental state in hospital nurses. The participants will be junior nurses who work in inpatient wards and are not clinically depressed. The participants will be randomly allocated to four intervention arms: 1) Mindfulness-based stress management program plus omega-3 fatty acids pills ; 2) Mindfulness-based stress management program plus placebo pills; 3) Psychoeducation leaflet plus omega-3 fatty acids pills; and 4) Psychoeducation leaflet plus placebo pills. Thirty participants will be allocated to each arm. These interventions will terminate until three months from registration for each participant. Information about depression and anxiety symptoms (primary outcome), insomnia, burnout, presenteeism, quality of life, sick leave, consultation about mental state of herself, and oxidative stress will be collected at 3 months, 6 months (primary time point) and 12 months from registration for each participant.
This study looks at the effects of a protocolized music therapy intervention on state anxiety for patients with cancer undergoing simulation for radiation therapy. Simulation, which is an imaging and diagnostic procedure, has been identified as producing significantly high levels of anxiety in many cancer patients.
Background: There is need for more effectiveness studies concerning treatment of emotional symptom problems indicating anxiety and depression in adolescents. SMART is the only treatment manual for combined emotional disorders developed in Norwegian. Purpose: To find the best individualized treatment for adolescents with emotional difficulties by: Finding criteria for the selection of appropriate patients for treatment with cognitive-behavior therapy program SMART in an outpatient population (14-18 years). Finding predictors of completion of treatment program SMART. Examining the effects of treatment with the SMART program at 6 months follow-up. Design: A randomized controlled study in six outpatient clinics in the north of Norway. N= 160 referred adolescents (14-18 years) with score above 6 on the Emotional Problems scale of the Strength and Difficulties Questionnaire (SDQ). Two thirds are treated according to the SMART-manual immediately, while the waiting list control group is treated with SMART after six weeks. Hypothesis: The SMART treatment is an effective treatment for emotional symptom problems. Publication: The results sought published internationally and nationally and will be communicated to clinicians.
This study is being conducted in GOA India. The study addresses specific issues of depression prevention in older adults living in low- and middle income countries (LMICs), by developing risk-reduction strategies through the use of lay health counselors. We will be training Lay Health Counselors (LHC's) to deliver simple behaviorally oriented interventions, designed to enhance the ability to relax, to improve active coping via better problem solving, and to increase protective factors such as good quality sleep. Lay Health Counselors are inhabitants of Goa. The aim of phase 1 is to create a depression and anxiety prevention intervention for use by lay health counselors. We will test the feasibility and acceptability of Problem Solving Therapy for Primary Care (PST-PC) and Brief Behavioral Treatment for Insomnia (BBTI). The products of phase 1 will be a prevention and counseling manual to standardize the implementation of the interventions for further testing in a randomized prevention trial (Specific Aim 2) and the adaptation of PST-PC and BBTI for the Indian population. In Phase 2, we will: gather data on the feasibility of identifying, enrolling, randomizing and retaining participants; implement the experimental intervention and enhanced usual care; identify "real world", barriers and develop strategies for addressing them; and assess the fidelity of the interventions.
Test anxiety is a well-known phenomenon in general population, but only few scientific advances have been made in order to fully understand and prevent this circumstance. The number of students which use neuro enhancement to improve their performance and to prevent test anxiety, is increasing. A US-survey estimated that almost 7% of students in US universities have used prescription stimulants against anxiety, and that on some campuses, up to 25% of students had used them in the past year. Acupuncture might act as an alternate. Several trials could demonstrate, that different forms of acupuncture could relieve symptoms of pre-exam anxiety syndrome significantly and that this therapy was highly safe. In special, the investigation of single point effects in test anxiety could be of general interest. The acupuncture point with the most convincing evidence up to date is Heart 7. Yet, its effectiveness has mainly been chosen in combination with other acupuncture points and not as single remedy in test anxiety. Therefore we establish a trial investigating the immediate needling effects at Heart 7 on the reduction of test anxiety. Therefore qe implemented a validated stress test, the Trier Social Stress Test TSST, which is known to provoke serious stress responses in healthy subjects. 24 medical students with test anxiety in there history will be randomised to two interventional groups (verum acupuncture and laser acupuncture), being treated and then pass this test. Main outcome is the increase of cortisol in saliva, which is the standardized measure of stress response used in this paradigm.
