We discuss the twist-3 contributions to the double-spin asymmetry A_{LT} for light hadron production in collisions between transversely and longitudinally polarized protons. So far only twist-3 effect in the transversely polarized proton have been studied for A_{LT}. In this talk, we discuss other possible twist-3 contributions in order to derive the complete leading-order cross section formula for A_{LT}.
