As 4 PhD students leave for internship (😭), @stresslab.bsky.social is excited to welcome 3 PhD students: Andrew Rolles, Dominique Sheldon, Jeniska Rivera Galarza.

Excited for this dream team to bring new ideas & energy to the lab. I couldn't do it without the support of @benjaminwkatz.bsky.social!

So (so, so, so) proud of Dr. Reina Kiefer for successfully defending her dissertation! Reina's work reflects an unwavering commitment to women who have experienced college campus sexual assault and will undoubtedly have a meaningful impact on their lives.

We are so grateful for your support ❤️

I don't recommend it 😂 Fortunately, this group made the process smooth/easy.

Congratulations!!! @katherineaberry.bsky.social

Congratulations to @stresslab.bsky.social graduate students on a successful match day 🥳

3/ Our finding broadly provide psychometric support for using the 20-item PCL-5 in intensive longitudinal studies

2/ Results indicated lower but acceptable discrimination for PCL-5 items 8 (traumatic amnesia), 16 (reckless or self-destructive behaviors), and 17 (hypervigilance). DIF analysis indicated that Item 2 (nightmares) exhibited DIF indicating potential bias; however, the effect sizes were negligible.

Psychometric evaluation of the Posttraumatic Stress Disorder Checklist for DSM-5 in daily surveys: An item response theory and longitudinal measurement invariance analysis The Posttraumatic Stress Disorder (PTSD) Checklist for the DSM-5 (PCL-5) has demonstrated excellent psychometric qualities across cross-sectional stud…

Interested in using the PCL-5 to measure PTSD symptoms in your EMA study?

We conducted item analysis to examine item thresholds & discrimination parameters & examined DIF across daily surveys

2/ Compared to those without PTSD, individuals with PTSD were less likely to decrease opioid use over the 60-day period. Although individuals with PTSD were less likely to increase their engagement with opioid treatment, individuals with PTSD engaged in treatment at much higher levels.

Influence of Posttraumatic Stress Disorder on Daily-Level Trajectories of Opioid Use Among Trauma-Exposed Individuals in the Community Who Use Opioids Objective: Individuals who use opioids are at elevated risk of posttraumatic stress disorder (PTSD). The objective of this study was to examine the influence of PTSD diagnosis on opioid use outcome...

Studied PTSD and opioid use across 60 days in people in the community who use opioids and have a history of trauma.

75% met criteria for current OUD

2/ Findings suggest an important role of emotion dysregulation in modulating stress, and underscore the need for additional research in this area.

📣 New Pub 📣

We captured 30-day emotion intensity & dysregulation data from EMA & examined in relation to cortisol (from hair) during the same period. Emotion intensity & hair cortisol levels were significantly associated among women with high (but not low) emotion dysregulation.

We're the lucky ones -- grateful for you!

Thanks to everyone who braved the early hour to attend our panel discussion on treating PTSD and substance use disorders!

With @nicoleweiss.bsky.social

So proud of Alexa Raudales for being the recipient of the @istss.bsky.social Outstanding Student Achievement Award

Thank you!

Congratulations to you too!

Thank you!

Went to dinner last night with @heatherschatten.bsky.social & our new R01!!! We're using the BACtrack Skyn & EMA to examine the timing & mechanisms underlying alcohol use & suicide risk.

I'm excited to be doing work that matters with close friends (also @lesliebrickphd.bsky.social and Amy Stamates)

Congratulations, Reagan!!!

Congratulations to you and Amy (now my URI BFF haha), and thanks for sharing your journey. I've been patiently waiting on an R01 (2nd percentile score in 10/24, council moved twice and finally happened in 05/25, pending status 05/25, JIT 06/25, second JIT 09/25). This feels like madness.

Proud to empower our community through naloxone distribution on IOAD. Community engagement is more than research; it's action. @nicoleweiss.bsky.social @benjaminwkatz.bsky.social @hodiana.bsky.social (and many others!)
