How to Implement Trauma-informed Care to Build Resilience to Childhood Trauma

---

Resilience to Childhood Trauma

When parents, service providers, and programs employ a resilience framework to childhood trauma, they understand there are always opportunities to support positive developmental trajectories among children, even if they have experienced trauma. Resilience has been defined as “a dynamic process encompassing positive adaptation within the context of significant adversity.”[28] Resilience is not a personal trait that individuals do or do not possess (thus, the term “resiliency” is best avoided because it connotes an individual characteristic),[29] but rather a product of interacting factors—biological, psychological, social, and cultural—that determine how a child responds to traumatic events.[30]

Resilience to trauma can be defined in several ways: positive child outcomes despite exposure to trauma, prevention of trauma recurrence despite high risk for further exposure, or avoidance of traumatic experiences altogether in the face of significant risk. All three of these conceptualizations of resilience are based on an ecological approach.

Ecological approach to resilience. Using an ecological approach to promote resilience in development among children who experience trauma is useful because it assumes that there are multiple levels of influence on a child’s development—the individual, parent, family, school, community, and culture—which may increase or decrease a child’s risk for and response to experiencing trauma. These various influences are often referred to as risk and protective factors.[31]

Risk factors. Risk factors are circumstances, characteristics, conditions, events, or traits at the individual, family, community, or cultural level that may increase the likelihood a person will experience adversity (e.g., childhood trauma, re-traumatization, or negative outcomes due to trauma).[32],[33] Risk factors for specific types of trauma may vary, but commonly include living in poverty, a lack of social supports, and prior history of trauma.[34],[35] Additionally, children who identify as lesbian, gay, bisexual, transgender, or queer (LGBTQ)[36] and children in military families[37] are at an increased risk for experiencing trauma. However, the presence of risk factors or membership in a high-risk group does not necessarily mean that a child will experience trauma or its most adverse effects.[38] Protective factors can buffer children from risk and improve the odds of resilient functioning.

Protective factors. Protective factors are characteristics, conditions, or events that promote healthy development and minimize the risk or likelihood a person will experience a particular illness or event, or its related negative outcomes.[39] Research shows that the strongest protective factor linked with resilience to childhood trauma is the reliable presence of a sensitive, nurturing, and responsive adult.[40] The presence of such a figure can help children by restoring a sense of safety, predictability, and control; giving them the feeling of safety; providing them a way to process traumatic events; protecting them from re-traumatization; supporting their development of self-regulation; and helping them heal.[41], [42],[43],[44]

In addition, the National Child Traumatic Stress Network highlights the following protective factors that promote resilience to childhood trauma:[45]

• Support from family, friends, people at school, and members of the community
• A sense of safety at home, at school, and in the community
• High self-esteem and positive sense of self-worth
• Self-efficacy
• Spiritual or cultural beliefs, goals, or dreams for the future that provide a sense of meaning to a child’s life
• A talent or skill in a particular area (e.g., excelling in school or in a sport)
• Coping skills that can be applied to varying situations

Finally, resilience to childhood trauma depends largely on the supports available to a child and his or her family. Family members, teachers, mental health providers, child welfare workers, and other community service providers can work together to ensure that children and families receive the emotional and concrete supports (e.g., food, shelter, financial stability) they need.[46] This system of care approach is also a cornerstone of TIC.[47]

Trauma-informed Care

The context in which children live, learn, and grow shapes both their immediate and long-term well-being.[48] Accordingly, children who experience trauma are more likely to exhibit resilience when their environments are responsive to their specific needs. Families, schools, community-based programs and services, and the individuals caring for children can increase the chances of resilience following childhood trauma when they become aware of the impact of childhood trauma, provide a sense of safety and predictability, protect children from further adversity, and offer pathways for their recovery. In other words, children benefit when these entities provide them with trauma-informed care (TIC).[49]

Implementing TIC with child-serving programs, institutions, and systems

Despite its focus on trauma, TIC is inherently a strengths-based perspective that emphasizes resilience instead of pathology.[50] TIC has been defined and implemented in a number of ways, but the Substance Abuse and Mental Health Services Administration has identified four key elements—the Four Rs (see description of each “R” below)—that can be used broadly across programs, institutions, and services.[51]

Applying TIC to real-world settings begins with a child’s first contact with a program, institution, or service system. It requires a comprehensive and multi-pronged effort involving the many adults in children’s lives. For example, in a school or afterschool program, TIC means increasing trauma-related knowledge and skills among program facilitators, school administrators, bus drivers, food service workers, classroom assistants, administrative staff, volunteers, teachers, leadership, special education professionals, school social workers and psychologists, families, and anyone else who comes into contact with children. However, increasing trauma knowledge is only one aspect of TIC, which also means that the individuals who care for children must be able to:

1. Realize the widespread nature of childhood trauma and how it impacts the child’s emotional, social, behavioral, cognitive, brain, and physical development, as well as their mental health. In addition, adults must be aware of the influence of trauma on family members, first responders, service providers, and others who may experience secondary stress (trauma-related reactions to exposure to another person’s traumatic experience).[52],[53] In some instances, adults endure the same traumatic events or circumstances as the child (e.g., a natural disaster, community violence, death of a community member) and may benefit from similar supports.
2. Recognize the symptoms of trauma, including how trauma reactions (i.e., symptoms of posttraumatic stress) vary by gender, age, type of trauma, or setting. In addition, the adults in children’s lives must understand that a child’s challenging behaviors are normal, self-protective, and adaptive reactions to highly stressful situations, rather than viewing that child as intentionally misbehaving. Children’s trauma reactions are understood to be adaptive efforts to protect themselves in response to traumatic events. For example, a child may be hypervigilant to an adult’s anger or disapproval because, in the past, he or she experienced physical abuse by a parent. Or, a child may disassociate or daydream as a learned response that enables them to avoid feeling or thinking about a traumatic experience.[54] In addition, TIC means recognizing that trauma may influence a child’s engagement in activities and services, interactions with peers and adults, and responsiveness to rules and guidelines.[55]
3. Respond by making necessary adjustments, in their own language and behavior, to the child’s environment; and to policies, procedures, and practices to support the child’s recovery and resilience to trauma.[56]
4. Resist re-traumatization by actively shaping children’s environments to avoid triggers (sounds, sights, smells, objects, places, or people that remind an individual of the original trauma) and protect children from further trauma, which can exacerbate the negative impacts of trauma and interfere with the healing process.[57],[58]

Training and professional development on child trauma is an important first step in TIC. Providing adults (staff, leadership, families, and community partners) with training and professional development on childhood trauma is an important component of implementing TIC.[59] It is essential that adults become aware of the prevalence and impact of trauma, and learn to apply a “trauma lens” (i.e., gain the capacity to view children’s difficulties in behavior, learning, and relationships as natural reactions to trauma that warrant understanding and sensitive care).[60] In addition, adults can learn key strategies to manage trauma-related problems in childhood. These include creating environments that feel physically and emotionally safe; teaching children self-regulation, language and communication skills, and how to build healthy relationships; learning each child’s trauma triggers and how both the child and adults can limit, anticipate, and cope with them; and supporting the development of healthy attachments with parents and other caregivers, as well as positive relationships with peers. Evaluations of TIC initiatives also indicate that when parents, service providers, and programs share a common language and view of trauma, they are better able to work together to meet children’s needs.[61]

Training and professional development opportunities are also important for increasing the capacity of adults to attend to other aspects of TIC, including family engagement; practices that are responsive to culture, gender, and sexual orientation; collaboration with community service providers (e.g., mental health providers who can screen for childhood trauma and provide evidence-based treatment); developing and integrating emergency and crisis response protocols; and establishing trauma-informed policies that support positive youth development despite exposure to trauma. Building capacity and maintaining an ongoing commitment to TIC efforts are critical to sustainability.[62], [63] However, although it is a critical component of TIC, training staff and parents on the impact of childhood trauma is not sufficient and does not in and of itself constitute TIC. TIC must also include comprehensive, ongoing professional development and education for parents, families, school staff, out-of-school program staff, and community service providers on jointly addressing childhood trauma.

Parents and service providers who work with children who experience trauma require self-care to prevent and mitigate the effects of secondary traumatic stress. TIC also means attending to the psychological and physical safety and well-being of the adults who care for children who have experienced trauma.[64], [65] Professionals, parents, and other caregiving adults may suffer secondary traumatic stress (trauma-related reactions to exposure to another person’s traumatic experience).[66],[67] Psychoeducation (helping others understand the impact of trauma, both on affected individuals and on their service providers, as well as pathways toward recovery),[68] skills training, high-quality supervision, and self-care (e.g., rest, exercise, social support, mindfulness and other stress reduction activities, engaging in pleasurable activities and hobbies, psychotherapy) are critical to ensuring adult well-being and providing sufficient personal resources to work effectively with children who are exposed to trauma. See Figure 4 for specific strategies recommended by the National Child Traumatic Stress Network to combat secondary traumatic stress and reduce related staff burnout and turnover.[69]

Further research is needed on TIC in child-serving programs, institutions, and systems to develop a sufficient evidence base to inform policy and practice. TIC is a relatively new framework for working with individuals who experience trauma, and the evidence base in support of its effectiveness is in the early stages of development. However, a number of promising TIC initiatives in early care and education, schools, child welfare, and behavioral health have demonstrated improvements in trauma-related knowledge and skills among service providers, foster parents, and family members; reductions in children’s posttraumatic stress symptoms and problem behaviors; and increases in children’s strengths and protective factors.[70],[71],[72],[73],[74] In addition, a growing number of clinical treatment models—including Trauma-Focused Cognitive Behavioral Therapy,[75],[76] Child-Parent Psychotherapy,[77],[78] Attachment and Biobehavioral Catch-up,[79],[80] and Parent-Child Interaction Therapy,[81],[82]—have undergone rigorous evaluation and shown positive outcomes for children from infancy to late adolescence. However, TIC is not limited to mental health professionals. Each child-serving program, institution, or service system can play a role in TIC, including referral to clinical treatment and follow-up with families.

Conclusion

Trauma-informed programs, institutions, and service systems are critical to promoting and fostering resilience in all children, and particularly those who have experienced trauma. TIC requires comprehensive, multi-pronged support from adults in all aspects of children’s lives. It includes increasing adults’ knowledge of childhood trauma and helping them recognize the symptoms, as well as giving them the resources to support and refer children who have experienced trauma to appropriate services. Additionally, as programs make their services more trauma-informed, it is important that they promote self-care to prevent or address secondary trauma among adults working with children who have experienced trauma.
