description The complete next to leading logarithmic [O(α<sub>s</sub>)] corrections to the spin-dependent weak deep inelastic structure functions g<sub>1</sub>,g<sub>3</sub>, and g<sub>4</sub> are calculated using dimensional regularization within the HVBM method. Analyzing the quark- and gluon-initiated contributions to these corrections for different values for the quark masses, a consistent factorization prescription for spin-dependent quark distributions, which safely removes soft contributions, is defined. It is shown that within this scheme, quark-initiated corrections are comparable in magnitude to those of gluonic origin, even though their contributions to the moments are small.
