Acetaminophen and Social Processes

Ohio State University9 enrolled

Overview

Recent research has identified heightened sensitivity to social rejection as a core feature of BPD. Rejection sensitivity can trigger the aggressive, impulsive, and self-injurious behaviors characteristic of the disorder. Therefore targeting therapy towards the reduction of rejection sensitivity may improve the low rates of effectiveness of current pharmacological and behavioral therapies. Therefore, this proposal tests a theoretically-based pharmacological approach that specifically targets the heightened sensitivity to rejection experienced by BPD patients. In prior research with normal controls, it was shown that chronic treatment with the physical pain-killer acetaminophen (e.g. Tylenol) reduced both neural responses to social rejection (using fMRI) as well as self-reported feelings of rejection in a daily diary study. It is the aim of this research project to determine if the over-the-counter analgesic, acetaminophen (active ingredient in Tylenol), can reduce symptoms and behaviors in BPD patients. The goal of this proposal is to use an open-label design to determine if acetaminophen improves symptoms in BPD patients.

Outcomes

Primary Outcomes

Change from baseline in symptom reports on the PAI-BOR at week 6

Symptom reports on the PAI-BOR.

Time frame: Baseline, Week 6

Change from baseline in symptom severity on the Zanarini Rating Scale for Borderline Personality Disorder

Zanarini Rating Scale for Borderline Personality Disorder

Time frame: Baseline, Week 6

Secondary Outcomes

Symptom Reports

Each week participants will be emailed a link to complete that will have three surveys. 1. The Beck Depression Inventory 2. The Beck Anxiety Inventory 3. The Inventory of Interpersonal Problems (Aggression and Interpersonal Sensitivity Subscales). This weekly survey report will also be sent to the participants once after the completion of pharmacotherapy (at the two weeks post cessation treatment).

Time frame: Baseline, weeks, 1,2,3,4,5,6 and 8.

Daily Diary

The importance of these measures will be to assess how rejected, aggressive, and social participants have been in order to determine if acetaminophen affects these proclivities. Participants will report on: hurt feelings, rejection, affect, aggressive feelings, impulsive behaviors, alcohol use, sleep, social interactions, perceived stress, self-esteem

Time frame: Daily for week 0,1,2, and 3
