Lab Projects

The TVA lab values teamwork and collaboration. While individual lab members pursue research endeavors in their particular area of interest, they also contribute their knowledge and expertise to other lab projects. This allows the TVA lab to explore diverse research areas relating to various aspects of trauma, violence, and abuse. Below is a sample of the research projects currently being conducted by the TVA lab members and faculty collaborators. Dr. DiLillo serves as a supervisor/collaborator on the following ongoing projects (student names and other collaborators listed in parentheses).  

Comparison of Written Versus Spoken Exposure Therapy (Haws, Andrews): This study is examining modifications to Written Exposure Therapy for treating PTSD in collaboration with Dr. Trey Andrews and the Latinx Mental Health and Treatment Outcomes Lab.

Emotion Dsyregulation and PTSD (Haws, Brockdorf, Messman-Moore, Gratz): This study is examining the bidirectional relations among symptoms of PTSD and emotion dysregulation using network analysis.

Using VR to Assess the Efficacy of a Motivational Interviewing Intervention to Increase Bystander Behaviors (Grandgenett, Gervais): This study uses virtual reality to examine the efficacy of a novel motivational interviewing intervention to increase bystander behaviors.

IPV and the Stress Spillover Hypothesis (Grandgenett, Franz, Calkins, Brock): The purpose of this study is to examine IPV and the stress spillover hypothesis (i.e., that general life stress will "spill over" into the couple's conflict management style) in pregnant couples. This project is being conducted in collaboration with the Family Development Lab under Dr. Rebecca Brock.

Roles of bystander intoxication and perpetrator status in bystander effectiveness (Steel, Grandgenett): This study examines two factors—bystander alcohol intoxication and perpetrator social status—that may influence the effectiveness of popular bystander intervention programs.

Objectification and Bystander Intervention (Brockdorf, Eagan, Gervais): This study examines how objectification may impact bystander efficacy through perceived barriers to bystander intervention in both men and women.

Service Utilization Barriers Among Undergraduate Sexual Assault Survivors (Brockdorf, Kumar, Jaffe, Holland): The purpose of this project is to examine the role of assault characteristics and responses in predicting perceived barriers to seeking mental health services. This study is being conducted in collaboration with Dr. Katy Holland.

Does partner support buffer the effects of PTSD on daily distress and experiential avoidance?: (Franz, Brock): The purpose of the current study is to examine the stress-buffering role of partner support in reducing daily emotional distress and experiential avoidance resulting from elevated PTSD symptoms. We hypothesize that the detrimental impact of PTSD symptoms on daily trajectories of positive emotion, negative emotion, and experiential avoidance (across 14 days) will be weaker to the extent that partner support is of high quality.  This project is being conducted in collaboration with Dr. Rebecca Brock's lab.

Longitudinal Assessment of Interpersonal Victimization in Undergraduates (Jaffe, Kumar): This longitudinal study is designed to examine the nature of sexual assault and dating violence victimization in college men and women. Risk factors for revictimization and PTSD (e.g., alcohol use, posttraumatic cognitions, social support) will be examined.

Alcohol, Sexual Objectification, and Sexual Aggression Study (Haikalis, Franz, Gervais): This study utilized an experimental approach and eye tracking technology to test the impact of alcohol intoxication on sexual objectification and sexual aggression in a lab-based setting. We are now examining sexual objectification as a mediator between acute intoxication and lab-based sexual aggression. This project is being conducted in collaboration with Dr. Sarah Gervais' lab.
