The purpose of this study is to examine whether Staying Strong With Schools, a school-based intervention to support military-connected children, will be helpful for school professionals and military parents in supporting specific needs of this population of children. As part of the partnership between three school districts in Massachusetts and the Red Sox Foundation and Massachusetts General Hospital Home Base Program, the investigators will examine the efficacy of a training delivered to these schools. The schools will be randomly divided into two groups (like a toss of a coin). Half of the schools will receive the training in 2014-2015, and the other half will be waitlisted and receive the training the following year (2015-2016). All participants (school teachers, military-connected children, and their parents) will be asked to complete questionnaires the first year. The investigators hypothesize that, compared to the control schools, at the end of the school year, SSWS schools will be associated with: (1) greater sense of competence and quality of relationships with military-connected children (MCC) among school professionals; (2) lower parental distress and increased parental sense of competence and general family functioning; and (3) increased social support, and fewer academic, emotional, and behavioral problems among MCC. The investigators hypothesize that an increase in school professionals' sense of competence in identifying and handling MCC's needs, increased quality of relationships with MCC, lower parental distress, increased parental sense of competence, and increased general family functioning will mediate the efficacy of SSWS on MCC's social support and psychosocial functioning.
