We present a measurement of the branching fraction of the decay B{sup {+-}} {yields} {chi}{sub c0}K{sup {+-}} from a sample of 89 million B{bar B} pairs collected by the BABAR detector at the PEP-II asymmetric-energy B Factory at SLAC. The {chi}{sub c0} meson is reconstructed through its two-body decays to {pi}{sup +}{pi}{sup -} and K{sup +}K{sup -}. The authors measure {Beta}(B{sup {+-}} {yields} {chi}{sub c0}K{sup {+-}}) x {Beta}({chi}{sub c0} {yields} {pi}{sup +}{pi}{sup -}) = (1.32 {sub -0.27}{sup +0.28}(stat) {+-} 0.09(syst)) x 10{sup -6} and {Beta}(B{sup {+-}} {yields} {chi}{sub c0}K{sup {+-}}) x {Beta}({chi}{sub c0} {yields} K{sup +}K{sup -}) = (1.49{sub -0.34}{sup +0.36}(stat) {+-} 0.11(syst)) x 10{sup -6}. Using the known values for the {chi}{sub c0} decays branching fractions, they combine these results to obtain {Beta}(B{sup {+-}} {yields} {chi}{sub c0} K{sup {+-}}) = (2.7 {+-} 0.7) x 10{sup -4}.
