Translation of Fit & Strong! for Use by Hispanics With Arthritis: A Feasibility Trial of ¡En Forma y Fuerte!

This study evaluated the feasibility and effectiveness of translating the evidence-based program, Fit & Strong!, into a Spanish program, iEn Forma y Fuerte!. A single-group, quasi-experimental design (n = 34, mean age = 58.8 [8.1], 87.2% female, 87.2% reported speaking mostly Spanish) was used to assess implementation feasibility and the impact of iEn Forma y Fuerte! on arthritis-related outcomes in Hispanics with arthritis.
