Filter by:The proposed research will be the first study to focus on experimentally manipulating both injunctive and descriptive norms on social networking sites in order to elucidate the relationship between alcohol and abstainer displays on social networking sites and subsequent alcohol cognitions, use, and related negative consequences. Based on literature focusing on developmentally appropriate health models for adolescents, the Prototype Willingness Model (PWM) assumes that health-risk behaviors occur either when individuals have developed intentions to engage in a risk behavior (and these intentions vary as a function of attitudes and perceived injunctive norms) or through willingness to engage in risks (which varies as a function of perceived vulnerability to negative consequences, perceived descriptive norms , and prototypes). To fully understand the relationships between alcohol abstaining displays on social networking sites, we will examine 1) the role of descriptive and injunctive abstainer and user norms, when experimentally manipulated with SNS profiles, on willingness and intentions, subsequent alcohol use and related negative consequences among adolescents (age 1 5-20) 2) whether intentions and willingness mediate the relation between our experimental manipulation and subsequent alcohol use and negative consequences and whether 3) individual differences in social influence moderate the effect of the experimental manipulation on intentions, willingness, alcohol use, and negative consequences. We will test these aims by recruiting a community sample of adolescents (N = 300), living in the greater Seattle metropolitan area. Participants will complete a web-based baseline assessment and participate in an in-person experimental manipulation in which they are either assigned to see same-sex social networking site profiles of alcohol abstainers, abstainers +users, or a control condition where neither user or abstainer information will be provided. Immediately after the manipulation, participants will answer a series of questions about the profiles they just viewed and their alcohol-related cognitions. Participants will also complete a one-month in person follow up assessment to test for impacts on intentions, willingness, alcohol use, and related negative consequences. Additionally, individual differences in social influence will be examined as possible moderators o f the relationship between SNS-portrayed norms and our primary outcomes. This study is both significant and innovative in that it uses a theoretical perspective to experimentally test the impact of alcohol content, in particular abstainer norms, on Facebook on adolescent alcohol use and related cognitions. The results have the potential to inform preventative interventions while addressing NIH priorities.
The research project investigates in a randomized controlled trial the effectiveness as well as moderating and mediating factors of psychometric feedback to therapists. In the intended study a total of 423 patients, who applied for a cognitive-behavioral therapy at the psychotherapy clinic of the University Trier and suffer from a depressive and/or an anxiety disorder (SCID-interviews), will be included. The patients will be randomly assigned either to one therapist as well as to one of two intervention groups (CG, IG2). An additional intervention group (IG1) will be generated from an existing archivale data set via propensity score matching. Patients of the control group (CG; n = 85) will be monitored concerning psychological impairment but therapists will not be provided with any feedback about the patients assessments. In both intervention groups (IG1: n = 169; IG2: n = 169) the therapists are provided with feedback about the patients self-evaluation in a computerized feedback portal. Therapists of the IG2 will additionally be provided with clinical support tools, which will be developed in this project, on the basis of existing systems. Therapists will also be provided with a personalized treatment recommendation based on similar patients (Nearest Neighbors) at the beginning of treatment. Besides the general effectiveness of feedback and the clinical support tools for negatively developing patients, further mediating and moderating variables on this feedback effect should be examined: treatment length, frequency of feedback use, therapist effects, therapist's experience, attitude towards feedback as well as congruence of therapist's and patient's evaluation concerning the progress. Additional procedures will be implemented to assess treatment adherence as well as the reliability of diagnosis and to include it into the analyses.
This research examines a theoretically informed web-based personalized feedback intervention to reduce alcohol-related risky sexual behavior among young adult drinkers. To accomplish this objective the study has enrolled a national sample of 1200 young adults aged 18-20 and is in the process of assessing them at 3-, 6-, 9-, and 12-months. The investigators will evaluate the overall efficacy of the interventions based on the Prototype Willingness Model by comparing underage young adult drinkers randomly assigned to receive the reason-based pathway intervention (n=300), the social-based pathway intervention (n=300), or the integrated intervention based on the full Prototype Willingness Model (both pathways, n=300) to an attention control group (n=300). The investigators will examine whether changes in components of both the reasoned and social pathways and drinking mediate intervention efficacy on reducing alcohol-related risky sexual behavior. Past behavior and college student status will be evaluated as moderators of intervention efficacy. The proposed study is both significant and innovative in that it will evaluate brief interventions among a national sample of young adults attending and not attending college, will utilize social networking sites for participant recruitment, and will test the efficacy of interventions based on individual and integrated pathways of the Prototype Willingness Model.
This research will adapt an evidence based intervention for alcohol and other drugs and evaluate its efficacy on Prescription Stimulant Medication (PSM) misuse in a web-based format for use with college students who have misused PSMs.
The study is to examine the therapeutic effect of a brief version of biofeedback therapy (developed bu the research team) on panic disorder. It is a randomized controlled design. The severity of panic symptoms of two groups of panic patients (reveiving biofeedback therapy or not) were measured before and after the six week duration. Besides, the severity of anxiety, depressive, somatic symptoms, and physiological indexes were recorded.
Exposure to life threatening, traumatic and stress inducing events in general is an inevitable part of military combat service . Among individuals exposed to a traumatic event, approximately 85-90 % will develop a stress response from which they will recover without need for any medical intervention whatsoever. However, roughly 10-15 % will continue to suffer from post-traumatic symptoms along with depression or anxiety disorders1, . The prominent symptoms of post - traumatic stress disorder (PTSD), consists of reliving the event via invasive and painful memories that include: images, thoughts or feelings, night terrors, and extreme emotional distress that arise when exposure to external or internal cues similar to or symbolizing aspects of the traumatic event. Following this distress, behavioral avoidance of situations that trigger unpleasant memories may develop. Such mental stress may lead to avoidance of social situations and hinder normal daily functioning in a variety of contexts2. The question arises as to what distinguishes between those who are exposed to a traumatic event and recover spontaneously and those who fail to resume daily life and develop PTSD. Attempts to find personality and environmental risk factors for the development of PTSD have yet to yield any unequivocal conclusions. This has lead the scientific community to look for neuro-physical risk factors as well . Furthermore, evidence that early diagnosis and treatment of the disorder helps reduce the severity of post-trauma symptoms -stresses the need for the accurate localization of neurological risk factors and new immediate and/or preventative interventions. The aim of the present project is to develop a brain oriented training method for early preventive interventions of PTSD.
Force generation and force level control are important neuromuscular control mechanism for successful execution of movement for our daily activities. Impaired force level control is a major deficit of motor control in people with stroke. Electromyographic biofeedback (EMG biofeedback) has been suggested by researchers and clinicians to be a useful and effective tool for enhancing control of force level during motor skill learning for people with stroke. Based on the concept of motor-skill learning, practice with variable force levels may be more effective than practice with a constant force level to enhance movement performance. The EMG biofeedback provides a suitable tool for such practice of force level control and hence for motor skill learning. However, research literatures thus far have yet to provide convincing evidences to support this claim. Neural imaging studies have shown corresponding brain reorganization and neural plasticity following physical practice of movement skills in people with stroke. It is curious whether EMG biofeedback augmented physical practice of motor skills enhances brain reorganization. Using brain mapping techniques, in particular, the transcranial magnetic stimulation (TMS), we could investigate neural plasticity accompanying motor function changes induced by physical training, and hence may help to develop safer and more effective training parameters. The purpose of this study is to examine the effects of variable practiced EMG biofeedback training emphasized on force level control of the ankle muscle on balance and gait performance and the corresponding changes of corticospinal excitability using TMS in people with chronic stroke.
