Biological substrates of impulsivity and aggression; neurophysiological (EEG, ERPs) and neuropsychological correlates of substance use disorders, antisocial behavior and impulse control disorders; assessment and treatment of aggressive behavior.
This study will examine the association between impulse control and heart rate variability in people with alcohol use disorders and the feasibility of implementing heart rate variability training (breathing exercises) in these patients as a potential way to reduce the impulse to drink.
Impulse control may serve as an important mechanism of change in the treatment of alcohol use disorders (AUDs). Prior studies have also suggested a link between impulse control and heart rate variability (HRV), a physiological index of self-regulation. This study is designed to examine whether a direct association exists between impulse control and HRV in AUD individuals. In addition, the study will provide preliminary data regarding feasibility of implementing a breathing training to enhance HRV in this population. Results of this study should provide a foundation for future studies examining the effects of HRV training on impulse control and drinking in relation to AUDs.

In this study, Dr.
Leonard examined heavy drinking, cognitive functioning, and
marital satisfaction and conflict in 300 couples over a three-year
time period. Couples in which the husband, wife, both, or neither
are frequent heavy drinkers were recruited. Researchers tested
whether self-regulation skills, in conjunction with heavy drinking,
smoking, and other health issues, influence marital satisfaction,
marital stability, and marital conflict. Funded by an award of
$2,635,812 from NIAAA, 2007-2012.

In this study, Principal Investigator Kenneth Conner of the University of Rochester investigated variables that decrease risk for suicide attempts in young people ages 12 to 25. Three types of variables that decrease risk will be examined: 1) “promotive” factors that decrease risk directly, that is they show a direct, inverse relationship to substance abuse; 2) “protective” factors that serve as a buffer against risk by moderating (lowering) the potency of risk factors; 3) variables that are both promotive and protective. Informed by a social connectedness framework, Dr. Conner and colleagues focused on promotive and protective effects of connectedness to peers, school, parents, and family. In addition, they examined promotive and protective effects of social capital, a measure of the connectedness within a community. Finally, the investigation included whether or not the promotive and/or protective effects of connectedness to parents, etc. assessed during adolescence endure into emerging adulthood. The project was conducted by an experienced multi-disciplinary research team which included Dr. Rebecca Houston of RIA; Drs. Robert Bossarte, Peter Wyman and Xin Tu of the University of Rochester Medical School; and Dr. Victor Hesselbrock of the University of Connecticut Health Center. Funded by the Centers for Disease Control and Prevention to Dr. Conner with a subaward to Dr. Houston from the University of Rochester, 2010-2013.

Using a case-control study design, this study examined the roles of reactive aggression and social isolation in suicide attempts and the level of planning preceding attempts in treated alcoholics. This study was funded by NIAAA to Dr. Kenneth Conner, principal investigator on the study and assistant professor in the Department of Psychiatry at the University of Rochester Medical Center. Co-investigators in Rochester include Yeates Conwell, M. D., Paul Duberstein, PhD and Sean Meldrum, M. A. RIA Research Scientist Dr. Rebecca Houston was co-investigator on the study, managed data collection at two Buffalo sites, and supervised the Buffalo-based staff. Subaward to Dr. Houston from the University of Rochester, 2006-2011.
This project used a multi-modal measurement approach to the assessment of impulse control before, during, and after a cognitive behavioral treatment for alcohol dependence. Since it is likely that the decision to initiate drinking is indicative of a momentary lapse in impulse control for individuals with an alcohol disorder, this study 1) investigated whether changes in impulse control during treatment are related to alcohol use during treatment, as compared to pre-treatment and 2) whether changes in impulse control during treatment result in changes in post-treatment alcohol use, as compared to pre-treatment. A two-group design consisting of a Standard Assessment Group and a Frequent Assessment Group was used with men and women who met DSM-IV criteria for alcohol dependence to examine the multi-dimensional nature of the impulsivity construct. Results yet to be published will better define the role of impulse control as a potential mechanism of behavioral change and inform the development of subsequent avenues of investigation on this mechanism in the treatment of alcohol use disorders. Results will also provide information about refining existing treatments as well as developing new treatment methods. Dr. Houston’s co-investigators are Drs. Ronda L. Dearing and Gerard J. Connors of RIA, and Dr. Gregory G. Homish of UB’s Department of Health Behavior. Funded by a grant of $416,063 from NIAAA, 2007-2010.
Neurophysiological and Behavioral Characteristics of Heavy Drinkers & Aggressive Drivers (funded by UB Interdisciplinary Research Development Fund). Examination of the potentially interactive effects of aggressive driving and heavy drinking history on neurophysiological (event-related brain potentials; ERPs) and behavioral measures during a driving simulation task. (Award made to Changxu Wu, PhD, UB Industrial and Systems Engineering, subaccount to Rebecca Houston).
Transitional Mechanisms in the Relapse Process: A Pilot Study (funded by RIA Research Development Program). This pilot study is investigating the role of implicit responses (behavioral and neurophysiological) to alcohol cues as they relate to relapse.
