We present studies of the transverse momentum dependence of valence quark transverse and longitudinal spin distributions through measurements of spin-azimuthal asymmetries in Semi-Inclusive Deep Inelastic Scattering (SIDIS) of kaons using the upgraded JLab 11 GeV polarized electron beam and the CLAS12 detector with longitudinally polarized proton and deuteron targets. Measurements with kaons are complementary to measurements with pions and will provide additional information on the Collins fragmentation mechanism. The P{sub T} dependence of the double spin asymmetry provides additional information on the flavor and polarization dependence of transverse-momentum-dependent helicity distributions of quarks, which provides complementary to the Single-Spin Asymmetry (SSA) measurements access to spin-orbit correlations. The large acceptance of CLAS12 would allow simultaneous detection of scattered electrons and leading hadrons, providing information on the struck quark's flavor and transverse momentum.
