Professional overview
-
Dr. Thomas Kirchner is a clinical-health psychologist and methodologist interested in the analysis and graphical representation of longitudinal and geographic data, including methodologies that link individual behavior to the real-time context in which it occurs. Dr. Kirchner’s research targets momentary influences on the maintenance of health-related behavior utilizing both field-based (ecological momentary assessment) and laboratory-based paradigms. These geographic information systems and analytical methods can then inform public health, research, and policy.
As the Director and Principal Investigator of the mHealth (mobile health) Lab, Dr. Kirchner uses GIS to understand health-related behavior and decision-making in real time (e.g., how people make decisions about what they eat and drink, the places they go to exercise in their neighborhoods, the amount of time they spend outdoors, and whether they smoke cigarettes and/or marijuana). In the Lab, students apply mHealth tools to explore geospatial systems, technology, research, and community advocacy. Students learn how to leverage the power of their cell phones to collect data about neighborhoods and experiences.

348-359AbstractSmoking is thought to produce immediate reinforcement, and subjective satisfaction with smoking is thought to influence subsequent smoking. The authors used ecological momentary assessment (A. A. Stone & S. Shiffman, 1994) to assess cigarette-by-cigarette smoking satisfaction in 394 heavy smokers who subsequently attempted to quit. Across 14,882 cigarettes rated, satisfaction averaged 7.06 (0-10 scale), but with considerable variation across cigarettes and individuals. Women and African American smokers reported higher satisfaction. More satisfied smokers were more likely to lapse after quitting (HR = 1.1, p < .03), whereas less satisfied smokers derived greater benefit from patch treatment to help them achieve abstinence (HR = 1.23, p < .001). Cigarettes smoked in positive moods were more satisfying, correcting for mood at the time of rating. The best predictor of subsequent smoking satisfaction was the intensity of craving prior to smoking. Understanding subjective smoking satisfaction provides insight into sources of reinforcement for smoking.Patterns of intermittent smoking: An analysis using Ecological Momentary Assessment

365-376AbstractSmoking cessation interventions often target expectancies about the consequences of smoking. Yet little is known about the way smoking-related expectancies vary across different contexts. Two internal contexts that are often linked with smoking relapse are states associated with smoking abstinence and alcohol consumption. This report presents a secondary analysis of data from two experiments designed to examine the influence of smoking abstinence, and smoking abstinence combined with alcohol consumption, on smoking-related outcome expectancies among heavy smokers and tobacco chippers (smokers who had consistently smoked no more than 5 cigarettes/day for at least 2 years). Across both experiments, smoking abstinence and alcohol consumption increased expectancies of positive reinforcement from smoking. In addition, alcohol consumption increased negative reinforcement expectancies among tobacco chippers, such that the expectancies became more similar to those of heavy smokers as tobacco chippers' level of subjective alcohol intoxication increased. Findings suggest that these altered states influence the way smokers evaluate the consequences of smoking, and provide insight into the link between smoking abstinence, alcohol consumption, and smoking behavior.Predictors of residual invasive disease after core needle biopsy diagnosis of ductal carcinoma in situ

190-193AbstractAlthough much drinking occurs in social settings, there has been little testing of alcohol in groups. The authors examined the effects of alcohol on performance on a group decision-making task. Fifty-four unacquainted male social drinkers were randomly assigned to 3-person groups that consumed either alcohol (0.82 g/kg) or a placebo. After drinking, participants decided whether to complete a 30-min questionnaire battery or toss a coin and, pending the outcome of that toss, complete either no questionnaires or a 60-min battery. Alcohol groups were significantly more likely than placebo groups to choose the coin toss. Results highlight the potent effects of alcohol on group decision making and suggest that application of social psychological theory and methods to the study of alcohol is warranted.Effects of alcohol on controlled and automatic memory processes

R1236-44AbstractIntraventricular injections of vasopressin (VP) and antagonists with varying degrees of specificity for the VP receptors were used to identify the action of endogenous brain VP on 0.3 M NaCl intake by sodium-deficient rats. Lateral ventricular injections of 100 ng and 1 microg VP caused barrel rotations and a dramatic decrease in NaCl intake by sodium-deficient rats and suppressed sucrose intake. Intraventricular injection of the V(1)/V(2) receptor antagonist [d(CH(2))(5)(1),O-Et-Tyr(2),Val(4), Arg(8)]VP and the V(1) receptor antagonist [d(CH(2))(5)(1),O-Me-Tyr(2),Arg(8)]VP (MeT-AVP) significantly suppressed NaCl intake by sodium-deficient rats without causing motor disturbances. MeT-AVP had no effect on sucrose intake (0.1 M). In contrast, the selective V(2) receptor antagonist had no significant effect on NaCl intake. Last, injections of 100 ng MeT-AVP decreased mean arterial blood pressure (MAP), whereas 100 ng VP elevated MAP and pretreatment with MeT-AVP blocked the pressor effect of VP. These results indicate that the effects produced by 100 ng MeT-AVP represent receptor antagonistic activity. These findings suggest that the effect of exogenous VP on salt intake is secondary to motor disruptions and that endogenous brain VP neurotransmission acting at V(1) receptors plays a role in the arousal of salt appetite.
