Abstract:
Professional horticultural therapists are responsible for evaluating their programs to see if they are having the desired effect. A formal evaluation is also of interest to clients, administrators, funding sources, and others who must discriminate between the effectiveness of various health care services. To gather information for a formal report, programs with individualized goals and objectives must be evaluated on the collective results of the success or failure of each individual program. Programs with standardized goals and objectives rely on the collective pre and post test results to determine if their program is working. Evaluation methods for programs with generalized goals and objectives are the most difficult to evaluate and rely on a non-experimental approach, quasi-experimental approach, or classic experimental design. Once the information is collected, a formal program evaluation must be clearly written with recommendations for change. This report must be put into the hands of influential people to help secure funding, improve programs, and ultimately benefit the client.
