We have measured the transverse momentum distributions of charged hadrons in d+Au collisions at {radical}(s{sub NN})=200 GeV in the range of 0.5<p{sub T}<4.0 GeV/c. The total range of pseudorapidity, {eta}, is 0.2<{eta}<1.4, where positive {eta} is in the deuteron direction. The data has been divided into three regions of pseudorapidity, covering 0.2<{eta}<0.6, 0.6<{eta}<1.0, and 1.0<{eta}<1.4, and has been compared to charged hadron spectra from p+p collisions at the same energy. There is a significant change in the spectral shape as a function of pseudorapidity. As {eta} increases we see a decrease in the nuclear modification factor R{sub dAu}.
