The individual sessions intervention focuses on education, skills building, and support. It will be delivered in six sessions by telephone over three months. A Caregiver Notebook will include comprehensive materials for all sessions and topics. Treatment fidelity will be monitored and ensured through assessment of intervention delivery, receipt, and enactment. The intervention is targeted and individualized to the concerns of the specific caregiver and care recipient through a risk assessment. The Risk Assessment (RA) assesses the main caregiving risk areas for the specific caregiving dyad. The RA is used to tailor the intervention for care recipient behaviors or safety issues and/or caregiver centered issues/concerns related to health, physical and emotional well being, and/or social support.

For the education webinar sessions, topics addressing each of the caregiving risk factors topics but without the skills building or cognitive restructuring components present in the individual intervention sessions will be available online in webinars. The education webinar sessions will focus on general information about post 9/11 concerns, problem behaviors, caregiver health, caregiver emotional well-being, and red flags. Education webinar session participants will not receive the Caregiver Notebook until they have completed their 6 month interviews. Parents will be able to view all 6 webinars at any time during the first 3 months. Each session will last approximately thirty minutes through PowerPoint slide presentation format with a pre-recorded script.
