This report presents data collected during 1989-90 for the Adventure Program Incident Reporting Project, a joint project between the Wilderness Risk Managers Committee and the Association for Experiential Education. The project provides a means to educate interested parties about the risk management implications of different adventure activities, a comprehensive incident database for use in statistical analysis and trend analysis, and a central reporting forum for incidents in adventure programming. Programs were asked to estimate actual hours of participation by clients and staff for specific activities and for client groupings. The report also requested detailed information on each incident including a brief narrative. The first section of the report includes definitions of terms and models that were used for analyzing data. Section 2 provides descriptive statistics on incidents reported in the database. The 55 programs providing data included private and public instructional organizations, psychiatric hospitals, universities, county parks and recreation departments, camps, schools, 4-H programs, and court service programs. A total of 832 injuries and illnesses were reported, of which 433 were deemed serious injuries. Other data describe clients, activities, types of injury or illness, primary causes of injury or illness, injury rates, injury by time of day, and reinjury profiles. The last section includes narratives describing both near-miss situations and injury-producing incidents during games and initiatives, ropes courses, rock climbing, caving, cycling, snow skiing, canoeing, whitewater paddlesports, hiking, camping, backpacking, and transportation. The appendix includes information on the incident reporting project and a copy of the incident report form. (LP)
