Training for Lasting Change: Trauma-Informed Training Results in Improved and Sustained Individual and Organizational Knowledge, Attitudes, and Policies.

Trauma-informed care (TIC) trainings seek to improve individual and organizational recognition and care to individuals who have experienced trauma. However, whether TIC trainings result in long-term changes to an organization's policies and practices remains unclear. This article describes the effectiveness of a workshop designed to train professionals across disciplines in understanding and implementing TIC in their work and workplace. Between July 2021 and May 2022, participants completed a 2-day (approximately 12 hours) training in TIC that included didactics on cultural responsivity, the biological effects of trauma, the components of TIC, and how to deploy TIC within their organization. Prior to the training, participants completed a previously validated survey, the Survey for Trauma-Informed Systems Change, which evaluated their pre-training (T0) competency in TIC and the level of TIC within their organization. Within 48 hours following the training, participants completed a post-survey (T1). To evaluate the longer-term impact of the training, participants repeated the post-survey at 6 months post-training (T2). Over a 1-year period, 598 individuals (78% women, 20% men; mean age = 45.5 years) received training in TIC. There was a significant increase between the T0 survey and the T1 post-survey in self-assessed knowledge and attitudes; systemwide knowledge and attitudes; training, support, interaction, and environment; and awareness of cultural background at work ( values < .001), but not safety and acceptance at work ( = .06). Open-ended qualitative responses on the T2 survey, which probed what specific policies and/or practices had been modified within the participant's organization, revealed improvement in several key themes (training, policy, and communication). This unique trauma-informed didactic training resulted isn persistent quantitative and qualitative change within individuals and organizations. Most notably, the training yielded greater confidence in utilizing TIC practices and systemic change at the organizational level. The results suggest that a 2-day training in TIC can transform organizational training, policy, and communications.
