  Transverse momentum ($p_{\mathrm{T}}$) distributions of identified hadrons
produced in p-Pb collisions at $\mathrm{\sqrt{s_{NN}} = 5.02\ TeV}$ have been
measured at mid-rapidity (0 $< y_{\mathrm{CMS}} <$ 0.5) by ALICE. Particle
tracks are reconstructed using the central barrel detectors. Particle
identification is performed via specific energy loss, time-of-flight or their
characteristic decay topology over a wide transverse momentum range (0 GeV/c up
to 8 GeV/c).
  Spectral shapes and particle ratios are measured in six multiplicity classes.
They are compared with several model calculations and results from Pb-Pb
collisions at $\mathrm{\sqrt{s_{NN}} = 2.76\ TeV}$ and pp collisions at
$\mathrm{\sqrt{s_{NN}} = 7\ TeV}$ at the LHC. The results are discussed with
respect to possible collective effects in p--Pb collisions.
