Understanding features of community strength both on and off the military installation will help identify and address the needs of military families. This study introduced a measure to identify adequacy of community resources for military families. Using confirmatory factor analysis with data from 717 service users (M age = 37.3 yr., SD = 10.6) representing four large U.S. Army installations, two domains of community resource adequacy were identified: resources on the installation and resources off the installation. This measure could be used in health research with military families and in improving resources available to this population.
