The purpose of this study was to evaluate the benefits of participation in a one-day surf therapy program among youth at-promise. Participants (N=152) were predominantly Hispanic or Latino (71%), followed by Black or African American (18%), 57% were Female, and age ranged from 6 to 19 years. Participant drawings were rated to evaluate program process. The program outcome was evaluated through an observational one-group pretest-posttest follow-up design using the Children’s Hope Scale. A paired samples t-test found a statistically significant increase in mean scores on hope after participation. A one-way analysis of variance on a subsample (n=50) with one month follow up data found a statistically significant increase in mean scores on hope after participation and one-month after participation. Results suggest that the study participants experienced a significant increase in hope through their participation in the Jimmy Miller Memorial Foundation’s one-day ocean therapy program. Limitations of the study design and implications for research and practice are discussed.
