Using a sample of 2.59x10{sup 7} {psi}(2S) decays collected by the CLEO-c detector, we present results of a study of {chi}{sub cJ} (J=0, 1, 2) decays into baryon-antibaryon final states. We present the world's most precise measurements of the {chi}{sub cJ}{yields}pp and {chi}{sub cJ}{yields}{lambda}{lambda} branching fractions, and the first measurements of {chi}{sub c0} decays to other hyperons. These results illuminate the decay mechanism of the {chi}{sub c} states.
