Brief Summary
The aim of the present project is to develop and evaluate a novel and brief method of generalizing habituation (i.e., calming down after being upset) from an original learning context in the laboratory to other contexts inside and outside the laboratory. Specifically, the primary aim of this project is to evaluate whether novel habituation reminders (HRs) introduced following personally-relevant emotional stressors reduce acute negative emotions and psychological distress outside of an original learning context. Using a team of basic and applied scientists, over 4 years the investigators expect to screen 420 adult outpatients to enroll 250 study participants who have extreme difficulties with emotion regulation. These 250 participants will be randomly assigned to one of eight experimental groups, with the experimental design leading them through 1 or 2 of 3 project experiments. Actual enrollment: 372 adult outpatients signed consent and enrolled into the study. 222 participants were eligible and began the study. Out of the 222, 210 completed the study (as opposed to the desired 250). Experiment 1 will evaluate whether novel auditory HRs following personally-relevant emotional stressors differentially reduce psychological distress and negative emotions (via self-report and psychophysiology), compared to no HRs, within the same and different lab contexts after a 1 week delay. Experiment 2 will evaluate whether HRs differentially reduce negative emotions, psychological distress, difficulties with emotion regulation, and psychiatric symptoms, compared to sham sounds outside the laboratory across a 1 week period, using 8x daily assessments of distress and emotions and automated HRs/shams when acute negative emotions are present. An automated server and cellular phone system will be used to assess distress and emotional states and to deliver HRs/shams. Experiment 3 will examine the feasibility, acceptability, and preliminary effect size estimates when participants self-initiate the use of HRs in their daily lives across a 2 week period when acute negative emotions are present. The specific randomization rules across the 8 groups are explained in detail in the full protocol . Risks in this study may arise from 1) the assessment interviews and questionnaires, and 2) discussing and hearing self-reported distressing events. Initial analyses will focus on the success of randomization to groups. The investigators will examine group differences on possible covariates (e.g., demographic variables) and those that are different across conditions will be used as covariates. Preliminary analyses will examine distributional properties of primary outcome measures and correlations among outcome measures and possible covariates. The investigators will set alpha at .05 for all analyses of primary hypotheses. To examine the influence of psychiatric symptoms (compared to the HR) on primary outcomes, the investigators will examine the relationship between baseline clinically relevant psychiatric variables (e.g., symptom severity) and changes in SUDS, emotional arousal, and clinical outcomes over time and if appropriate include these variables in primary analyses. Full data analytic plans are described in the full protocol.
