These presentations offered comprehensive yet practical techniques to anyone who is currently engaged in or about to be engaged in evaluating a collaborative of non-profit service providers that are trying to expand access to behavioral healthcare services across a network. The presentations addressed the design strategies and issues associated with conducting such evaluations in Southeast Louisiana—one Post-Hurricane Katrina and one Post-BP Oil Spill. The presentations highlighted key contextual factors, data management, data validation, and other analysis issues that had to be considered in determining the value and relative implications of the findings generated from these evaluations. Common logistical challenges were identified, and these challenges were further confounded with balancing realistic expectations and values of the various stakeholders. Strategies to address these challenges and how to apply our lessons learned to other communities and settings were discussed.#BehavioralHealth #DisasterResponse #SocialWork #2011Conference #HumanServicesEvaluation #Collaboratives #DisasterandEmergencyManagementEvaluation
