Programs that offer therapeutic sessions that focus on the system of relationships and communication patterns among family members and which attempt to modify those relationships and patterns to achieve greater harmony. The therapist focuses on the family as a unit rather than concentrating on one of the members who is singled out as the person in need of treatment.

Programs that offer therapist-facilitated collective treatment sessions in which unrelated groups of individuals, couples or families discuss their attitudes, feelings and problems and, with input from other members of the group, attempt to achieve greater self and interpersonal understanding and adjustment and explore solutions to their problems.

Programs that offer personal therapeutic sessions in which the therapist works on a one-to-one basis with clients to help them resolve their mental, emotional or social problems.

Individual practitioners, programs, and/or systems whose approach to engaging people with a history of trauma involves recognition of the presence of trauma symptoms and acknowledgement of the role that trauma has played in their lives. The approach can be implemented in any type of service setting or organization and has been used in the delivery of a broad range of services including mental health, substance use, housing, vocational or employment support, domestic violence and victim assistance, and peer support. However, it is distinct from trauma-specific interventions or treatments that are designed specifically to address the consequences of trauma and to facilitate healing.
