The Use of Crisis Services Following the Mass School Shooting in Uvalde, Texas: Quasi-Experimental Event Study

Abstract

Background Mass shootings result in widespread psychological trauma for survivors and members of the affected community. However, less is known about the broader effects of indirect exposure (eg, media) to mass shootings. Crisis lines offer a unique opportunity to examine real-time data on the widespread psychological effects of mass shootings. Objective Crisis Text Line is a not-for-profit company that provides 24/7 confidential SMS text message–based mental health support and crisis intervention service. This study examines changes in the volume and composition of firearm-related conversations at Crisis Text Line before and after the mass school shooting at Robb Elementary School on May 24, 2022, in Uvalde, Texas. Methods A quasi-experimental event study design was used to compare the actual volume of firearm-related conversations received by Crisis Text Line post shooting to forecasted firearm conversation volume under the counterfactual scenario that a shooting had not occurred. Conversations related to firearms were identified among all conversations using keyword searches. Firearm conversation volume was predicted using a seasonal autoregressive integrated moving average model trained on the 3 months of data leading up to the shooting. Additionally, proportions of issue tags (topics coded post conversation by volunteer crisis counselors at Crisis Text Line after the exchange) were compared in the 4 days before (n=251) and after (n=417) the shooting to assess changes in conversation characteristics. The 4-day window was chosen to reflect the number of days conversation volume remained above forecasted levels. Results There was a significant increase in the number of conversations mentioning firearms following the shooting, with the largest spike (compared to forecasted numbers) occurring the day after the shooting (n=159) on May 25, 2022. By May 28, the volume reverted to within the 95% CI of the forecasted volume (n=77). Within firearm conversations, “grief” issue tags showed a significant increase in proportion in the week following the shooting, while “isolation/loneliness,” “relationships,” and “suicide” issue tags showed a significant decrease in proportions the week following the shooting. Conclusions The results suggest that the Uvalde school shooting may have contributed to an increase in demand for crisis services, above what would be expected given historical trends. Additionally, we found that these firearm-related crises conversations immediately post event are more likely to be related to grief and less likely to be related to suicide, loneliness, and relationships. Our findings provide some of the first data showing the real-time repercussions for the broader population exposed to school shooting events. This work adds to a growing evidence base documenting and measuring the rippling effects of mass shootings outside of those directly impacted.

The blood currency of suicidal mass shooters: 60 years of U.S. evidence

“…Mass shooting survivors, witnesses, and their families tend to suffer from severe mental and psychological trauma, such as post-traumatic stress disorder (PTSD), major depression, anxiety, and substance abuse (Abrams, 2022;Lowe & Galea, 2017). In addition, to the general public, mass shootings also lead to fears and a declined perception of public safety in society (Lowe & Galea, 2017), as extant literature shows that mass shootings increase depression and other mental health disorders among adolescents and adults in society (Abrams, 2022;Brenan, 2019;Weitzel et al, 2023). On top of the psychological impact, mass shootings also have far-reaching economic consequences.…”
