The goal of this randomized controlled trial is to learn about how to effectively help children (aged 7-12) who have developed moderate symptoms of posttraumatic stress after exposure to trauma, and prevent development of more severe problems. The main research questions are: * Will the parent-led, therapist assisted treatment "Stepping Together for Children after Trauma" (ST-CT) be more effective, compared to usual care, in reducing symptoms of posttraumatic stress, depression and sleep disorders, and in improving daily functioning for children and their parents after trauma? * Is ST-CT implemented to the municipal first-line services cost-effective? * Will ST-CT prevent use of health care services and prescribed drugs in the long term? The children and their non-offending caregivers will be randomized to receive treatment with ST-CT or usual care, and symptoms and general functioning will be assessed at five time-points.
Childhood trauma is a major public health challenge and affects a substantial number of children. Trauma impacts psychological and physical development, as well as long term mental and physical health and behaviour. These adverse outcomes can be prevented through appropriate treatment. Unfortunately, there is a substantial gap between the need for treatment and access to evidence-based care. Low-intensive treatments that utilize and strengthen family resources could contribute to bridging this gap and contribute to improving long-term public health and quality of life. The Stepped Care Cognitive Behavioral Therapy for Children after Trauma (SC-CBT-CT; Salloum et al. .2014) is a promising intervention for traumatized children that consists of two steps: 1) Stepping Together for Children after Trauma (Stepping Together CT, ST-CT), which is a parent-led, therapist-assisted treatment that takes advantage of and strengthens parent resources; and 2) Trauma-Focused Cognitive Behavioral Therapy (TF-CBT; Cohen et al. 2017) which is a therapist-led treatment provided when Stepping Together CT does not sufficiently help the child. Results from a recent randomized control trial (RCT) conducted in the United States, show that SC-CBT-CT is as effective as standard therapist-led TF-CBT in reducing post-traumatic symptoms, depression, sleep disturbance and parental distress, while simultaneously reducing treatment-related costs by 50% (Salloum et al. 2022). In Norway, a recent pilot study found that the first step, ST-CT, is well accepted by children, parents, and therapists, and is feasible as a first-line intervention in the municipal services (ClinicalTrials.gov Identifier: NCT04073862). The current study is an RCT with a hybrid effectiveness-implementation design where ST-CT will be implemented to municipal first-line service centers. Participants will be randomized to either the ST-CT or usual care (UC). We will recruit 160 child-parent dyads through 30 participating municipalities from 2023-2025. This will be the first RCT of ST-CT from an independent research group, with the potential for wider implementation which will greatly impact the resources and tools the municipalities have in facing challenges related to childhood trauma. Aims and data collection: 1\) Assess the effectiveness of the parent-led intervention in reducing symptoms on post-traumatic stress, depression, somatic pain and quality of life from both children and caregivers compared to UC. In addition, an objective assessment of quality of sleep will be recorded with a sensor that registers the child's sleep patterns; 2) Evaluate the cost-effectiveness and cost-utility of the ST-CT model; 3) Assess the potential preventive effect of the intervention through long-term follow-up data on use of health services from the Norwegian Patient Registry (NPR), the Norwegian Prescribed Drug Registry (NorPD), and Statistics Norway (SSB); and 4) Investigate barriers and facilitator for implementation, develop culturally adapted treatment material, and an implementation guideline. Assessments of the children and parents will be conducted by an independent assessor at five time points: T1 = baseline, T2 = after completion of the workbook (ST-CT)/9 weeks (UC); T3 = after the maintenance phase (ST-CT)/ 15 weeks (UC); T4 = 6 months after baseline; T5 = 12 months after baseline. A secondary aim is to investigate the change-processes within the ST-CT arm, including when during the treatment change in PTSS occurs and how change is related to parenting practices and the child's perceived relationship to their parent. Assessments related to change-processes will take place in the first 6-9 weeks of treatment, between T1 and T2, for participants in the ST-CT arm only. Specifically, we will collect a short post-traumatic stress symptom assessment (at each parent-child meeting at home, and the first four sessions with the therapist, altogether 15 times), and assess parenting practices and the child's perceived relationship to the parent (the first four sessions with the therapist).

ST-CT is Step One of Stepped Care CBT for Children after Trauma (previously called Stepped Care Trauma-focused Cognitive Behavioral Therapy; Salloum et al., 2014). It consists of five components: psychoeducation, stabilization, trauma narrative, in-vivo exposures and consolidation. The parent and child have 11 at-home-meetings and complete tasks in a workbook, Stepping Together (from the Preschool PTSD Treatment by Michael Scheeringa et al), over 6-9 weeks. In addition, there are weekly calls and five sessions with the therapist. Children who meet responder-criteria (i.e., no more than four symptoms of PTSS) continue to a 6-week maintenance phase, after which treatment is complete if the child still meets responder criteria. For those who do not meet responder-criteria, or are not able to complete the workbook, the responsibility for the treatment is transferred from the municipal service level to the corresponding child and adolescent mental health service (BUP).
Therapists in the control group will provide the treatment they usually provide, and develop a treatment plan in collaboration with the parents. This may consist of individual sessions with the child, parent sessions, group treatment, meetings with the school and other collaborating services, or referral to the second line mental health centres (BUP).

Child sleep quality: objective measure and sleep diary
A non-contact sensor (Somnofy radar, Vital Things A/S) will be used to assess the child's sleep quality in 7 days before treatment start. The sensor registers the child's movement, respiration frequency and sleep quality during the night. A sleep diary will be completed for the same 7 days, with parents recording: when their child falls asleep, wakes up, time taken to fall asleep, awake periods during the night and how well they slept; and the child reporting: if they woke up at time, how many times and how well they slept.
