  • Neural predictors of synergy between self-affirmation and message tailoring

    PI: Emily B. Falk, PhD

    We propose self-affirmation as a theory driven intervention to improve self-efficacy for physical activity in sedentary, overweight adults. In particular, we hypothesize that self-affirmation manipulations that focus on a participantís strengths, delivered prior to exposure to a targeted health communication, will reduce defensive processing of messages (e.g. counter arguing), increase self-efficacy to perform the target health behavior, and may lead to increased behavior change, compared to a non-affirmation control.

  • Social & Cognitive Neuroscience Core (CECCR2)

    PI: Thad A. Polk, PhD

    Ultimately, the goal of CECCR2 aims to understand why and how communication affects health-related behavior and decision making. Specifically, we want to know how tailoring communication by specific individual characteristics influences subsequent health behaviors. For example:How does tailoring a message about smoking influence smokersí subsequent decisions about quitting? How does tailoring a message about colorectal cancer affect peopleís willingness to get screened? How does tailoring information about prostate cancer affect patientsí subsequent conversations with their physicians about their treatment preference? A significant obstacle to answering these kinds of questions is that health-related decisions can have many different causes; and these causes can be difficult to disentangle using purely behavioral measures. We therefore want to incorporate measures that begin to address the underlying neural and cognitive mechanisms that give rise to the observed behaviors. (09/01/2008 - 08/31/2013)

  • Neural Bases of Effectiveness of Individually Tailored Smoking Cessation Messages

    PI: Hannah Faye C. Chua, PhD

    Study 1 explores the self-relevance dimension of message tailoring while Study 2 focuses on the adaptation of content from message tailoring. Each study has two phases: the first phase demonstrates neural substrate activation associated with specific aspects of tailored messages (fMRI); the second phase explores smoking cessation associated with brain region activations found in the first phase of the study.

  • Cessation Messages & Neural Activation

    PI: Hannah Faye C. Chua, PhD

    This study explores whether listening to high-tailored smoking cessation messages activates the rostral medial prefrontal region more than listening to linguistically comparable but low-tailored cessation messages. (09/01/2006 - 08/31/2007)

  • CECCR - Center of Excellence in Cancer Communications Research

    PI: Victor J. Strecher, PhD, MPH

    The purpose of the University of Michigan Center of Excellence in Cancer Communications Research (CECCR) is to develop an efficient, theory-driven model for generating tailored health behavior interventions that is generalizable across health behaviors and socio-demographic populations.
