Trauma has been found to be highly prevalent among individuals diagnosed with SMIs. Mental health professionals have been reported to misdiagnose or avoid addressing trauma in this population. There is a need to provide information about trauma and to foster awareness among mental health professionals who are treating individuals diagnosed with SMIs. With a TIC approach, operating from a recovery-oriented philosophy, there have been interventions created to address trauma and SMIs with the aim of developing awareness about trauma and the impact it may have on someone’s life. With these factors in mind, mental health professionals should be competent in TIC in order to provide effective treatment to this population in the future. This study investigated the impact of a trauma-informed care training program on mental health professionals’ knowledge, attitudes, and skills regarding clients who have been diagnosed with SMIs and may have experienced trauma. Despite the small sample size, the study found a significant increase of mental health professionals’ knowledge and attitudes from pre- to post-training evaluation. The results of this study suggest that the training had a positive impact on the professionals that attended and participated in this training. Implications and recommendations based on these findings were discussed.
