Traumatic experiences can have long-lasting negative effects on individuals, organizations, and societies. If trauma is not addressed, it can create unsafe cultures with constant arousal, untrusting relationships, and the use of coercive measures. Trauma-informed care (TIC) can play a central role in mitigating these negative consequences, but it is unknown how and in which way(s) TIC should be implemented. Our objective was to conduct a scoping review that systematically explored and mapped research conducted in this area and to identify existing knowledge about the implementation of TIC. The search was conducted on the CINAHL, Cochrane, Embase, ERIC, Medline, PsycINFO, and Web of Science databases, and more than 3000 empirical papers, published between 2000 and 2022, were identified. Following further screening, we included 157 papers in our review, which were mainly from the USA, Australia, New Zealand, and Canada, focusing on study settings, methodologies, and definitions of TIC, as well as the types of interventions and measures used. This review shows that TIC is a complex and multifaceted framework, with no overarching structure or clear theoretical underpinnings that can guide practical implementations. TIC has been defined and adapted in varied ways across different settings and populations, making it difficult to synthesize knowledge. A higher level of agreement on how to operationalize and implement TIC in international research could be important in order to better examine its impact and broaden the approach.

Constructing a coherent life story through the formation of self-event connections may help maintain unity in the self. We examined how positive and negative self-event connections were related to symptoms of psychopathology when controlling for two other measures of self-unity: self-concept clarity and dissociation. While most studies of life stories use content coding, we used a self-report method and hence provide a rationale for this method. One hundred five young adults identified life story chapters and rated them on self-event connections, including questions of positive or negative self-change and self-stability connections. They also completed scales measuring self-concept clarity, dissociation, and symptoms. Higher ratings of positive and lower ratings of negative self-event connections in life stories were related to fewer symptoms of psychopathology. Positive self-change was related to fewer symptoms when controlling for self-concept clarity and dissociation. The results suggest that positive and negative self-event connections are differentially related to symptoms of psychopathology. In addition, the results indicate that self-report measures of life stories may be a useful supplement to coding of narratives.

It has been proposed that schizophrenia reflects disturbances in personal identity, which include sense of personal agency, sense of belonging within a social group, and metacognition. Less is known about how these different processes are related to one another and to well-being outcomes. To study this, we measured themes of agency and communion in narrative identity in 29 individuals with schizophrenia and 29 individuals with HIV. All participants had previously been assessed on metacognitive abilities using the Indiana Psychiatric Illness Interview (IPII) and completed scales measuring hopelessness and self-esteem. For the present study, themes of agency and communion were coded from the IPII transcripts. Results indicated that participants with schizophrenia had lower levels of agency and communion compared with participants with HIV. More presence of agency and communion themes were related to better metacognitive abilities as well as less hopelessness and higher self-esteem across groups. Agency predicted variance in hopelessness after controlling for metacognitive abilities. The results suggest that although the construction of narrative identity may depend on metacognitive abilities, agency themes predict outcomes beyond metacognition.

While it is known that being mechanically restrained during hospitalization can, in severe cases, lead to PTSD in individuals with mental illness, less is known about why some develop posttraumatic...
