    Developing effective communication for climate change adaptation and disaster risk mitigation
    (2021) Lim, JungKyu Rhys; Liu, Brooke Fisher; Communication; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
    Preparing for natural disasters and adapting to climate change can save lives. However, little research has examined how organizations can effectively communicate climate change adaptation and disaster risk mitigation behaviors. This dissertation employs two studies to examine how to effectively communicate disaster mitigation and preparedness to help at-risk publics better prepare for natural disasters. Fragmented studies so far have not provided an integrated model to identify the most effective factors for explaining and predicting disaster preparedness behaviors and policy support. Moreover, studies have not yet developed and tested communication messages that can motivate publics’ disaster risk mitigation through experiments. Thus, in Study 1, this dissertation attempts to build an integrated model and identify the key factors that motivate disaster preparedness behaviors and policy support through three large-scale online surveys (N = 3,468). Two of the most common federally declared disasters in large disaster-prone states are studied: wildfires and hurricanes with floods. Study 1 finds that social norms and self-efficacy strongly motivate disaster preparedness behaviors, while response efficacy strongly motivates policy support behaviors. Then, based on Study 1 and consultation with eight communication experts, Study 2 develops messages using social norms and efficacy. Study 2 tests the social norms and coping appraisal messages through four between-subject online experiments (2 X 2 X 2 X 2) with an additional vicarious experience condition in flood- and hurricane-prone states (N = 5,027). Injunctive norms and disapproval rationale strongly encourage at-risk publics to take mitigation behaviors, and vicarious experience seems promising for message design. Additionally, this dissertation reveals at-risk publics’ awareness, behavioral engagement, preferred communication channels, and information sources for preparing for hurricanes and wildfire risks. Weather forecasters and the National Oceanic and Atmospheric Administration (NOAA), including the National Weather Service (NWS), were the preferred information sources for preparing for hurricane risks. Conversely, local and state fire departments were the preferred information sources for preparing for wildfire risks. By developing and testing messages on the strongest factors using preferred information sources, the dissertation provides guidance for risk communication researchers and professionals.

    CREATIVE PERSUASION: ENHANCING WELL-BEING AND SELF-EFFICACY THROUGH THEATRICAL PERFORMANCE
    (2018) Ganzermiller, Josie Deanna; Khamis, Sahar; Communication; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
    This manuscript is intended as a first step in exploratory research to examine the efficacy of creative performance in entertainment-based health interventions, as well as the cognitive mechanisms for that efficacy. Creative performance for the purposes of this study is defined as engaging in an activity that requires the participant to use his or her body to creatively portray a character and/or enact a message. While much is known about the efficacy of entertainment-based health interventions, less empirical work has focused on how merely participating in creative performance promotes well-being. Well-being is psychological and mental health, which is more than the absence of mental disorder or disease, but rather the state of "optimal psychological functioning and experience" (Ryan & Deci, 2001). This document outlines a panel study that evaluates the degree to which active involvement in an immersive theatre camp leads to increases in well-being and self-efficacy for adolescents, as well as the theoretical basis for expecting such a result. A front matter table (p. vii) provides a reference for the key concepts and variables included in the study. The following chapters expand on the rationale for this work, including entertainment-education, benefits of creative performance, and the importance of well-being in adolescence.

    A Meta-Analytical Test of Perceived Behavioral Control Interactions in the Theory of Planned Behavior
    (2013) Boudewyns, Vanessa; Fink, Edward L.; Communication; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
    This study used meta-analytic procedures to test for interaction effects among the components of the theory of planned behavior (TPB). The central hypothesis examined was that attitudes and subjective norms should perform less well in explaining intentions when perceptions of behavioral control are low. A traditional meta-analysis of nine studies that directly examined perceived behavioral control (PBC) interactions was conducted. A second meta-analysis--the main focus of this dissertation--was conducted that tested for two- and three-way interactions in which the presence of PBC interactions was investigated in 121 studies, which provided 154 data sets with 44,424 participants. In addition to testing for two-way PBC interactions, this meta-analysis also examined whether the presence of PBC interactions depended on other variables. Specifically, three-way interactions with type of behavior classification (i.e., public versus private, familiar versus unfamiliar) and type of PBC operationalization (e.g., self-efficacy, perceived difficulty, perceived control, or some combination of the three) were explored. Results indicated that attitude by PBC interactions exist but that the effects vary depending on the type of PBC operationalization and behavior context. In addition, meta-analytic structural equation modeling was used to examine whether the association between PBC and intention is mediated by attitude and subjective norms; however, no evidence for this relationship was found. Finally, results from an auxiliary analysis revealed that the attitude by PBC interaction on intention had statistically significant nonlinear effects in addition to a linear effect. In contrast, the norm by PBC interaction did not have statistically significant linear or nonlinear effects. The discussion highlights the effects of different meta-analytic techniques, the need for future investigation using experimental designs, the implications of these findings for further theory development, and practical implications for health communication researchers. In sum, through the use of a multi-faceted approach to quantitatively review attitude by perceived control and norm by perceived control interactions in the TPB, this study helped to address inconclusive results with regard to the existence and type of PBC interactions.
