Military life involves frequent movements requiring frequent and sometimes difficult life adaptations, especially for military families who have children with special needs. The problem addressed in this study is active-duty military families are not provided consistent family assistance or support for their children with special needs during relocation from the military affiliated service they serve or the schools. This often results in family stress and feelings of isolation. The purpose of this qualitative multiple-case study was to investigate the lived experiences of active-duty military families who have children with special needs during their permanent change of duty station. A theoretical framework integrating attachment theory and family systems theory guided the study. Eight families recruited via Facebook participated in semi-structured interviews; to be eligible for the study, they must have relocated within the past 2 years, be active duty in the Air Force, Army, Marine Corps, or Navy, and have a child with a special need. Nine major themes emerged from thematic analysis of the data to describe participants' lived experiences before, during, and after permanent change of duty station (PCS) with regard to challenges and supports, the consequences of their PCS experience on their child with special needs, and additional supports the military and schools could provide. Participants reported encountering specific challenges that impacted the availability of services for their children when relocating while being on active duty. Parents were required to focus efforts on advocating for their child, perceived minimal benefits to enrolling in Exceptional Family Member Program, and experienced minimal assistance from the School Liaison Officer. The parents reported their children experienced increased difficulty in adjusting to various school requirements and particular difficulty in creating new bonds. Participants suggested improvements in the relocation services the military states provide and the need for military family members to be engaged in conversations surrounding additional supports needed. Implications include the need to provide programs to help military families acquire information and maintain resiliency, thus enabling them to adapt quickly to new environments.
