Especially at times of crisis, there is a generally unmet need to help people come to terms with their emotional responses and facilitate ongoing emotional support. Internet-based research, in particular, has tremendous potential to identify needs and provide immediate solace and opportunity for self-reflection. Our experience using the Internet to assess responses after the 9/11 terrorist attacks and that of other similar research will be presented. We highlight key findings in the areas of denial, changes in worldview, growth, and resilience to illustrate the main factors which are predictive of adaptation. Our Internet findings suggest that the ability to express and come to terms with trauma-related emotions, use of effective coping strategies, maintenance of a supportive social environment, and cognitive reorganization and meaning-making can reduce distress in the long run and may lead to higher well-being and posttraumatic growth. We illustrate how the virtual world of the Internet may offer these opportunities.
