Parental deployment can disrupt the care children receive both as a result of deployment-related separation and the potentially destabilizing impact of deployment on the remaining caregiver and daily routines. This study will follow 230 intact military families with a child between 4-7 years in a longitudinal pre- mid- and post-deployment study. At Pre and post deployment, Service Members and their Spouses complete questionnaires and interviews regarding their psychological health, marital and family functioning, and parent functioning. Spouses complete questionnaires regarding childrens psych health and development at pre- mid- and post-timepoints. Children participate through doll and puppet play interview. Teacher ratings of the child are collected at all three timepoints. The objectives of this study are to 1 Determine the impact of Service Members post-deployment psychological health on children ages 4 to 7 years old, and 2Identify those particular Service Members Psychological Health-related symptoms that place children at risk for negative outcomes and assess the means by which these symptoms undermine childrens adjustment directly by the Service Member and indirectly via negative impact on the Spouse. Current progress includes successful IRB review and survey development. The PI changed institution and the award was transferred to her new institution. The US Marine Corps has agreed to host the study with the I Marine Expeditionary Force at Base Camp Pendleton. Data collection is underway.
