Using second quantization for scalar field, spinor field and vector fields, we can get commutation and anticommutation relations for the birth and destruction operators of the fields, which leads us to the Bose or to Fermi statistics. Is it possible to expand these results on a field of arbitrary spin (integer or half-integer), using the basic idea that each field can be built by combination of spinor $\frac{\hbar }{2}$ fields?

Suppose we assume that an object's statistics depend only on its spin and not on whether the object is composite or fundamental. This assumption seems natural, since if it failed, it would be too good to be true -- it would give us a way of finding out about the internal structure of any particle, at all scales, without having to build particle accelerators.
Given that assumption, the full theorem follows directly from the spin-1/2 case. Any spin can be realized by coupling spin 1/2's. Given that spin 1/2 has an eigenvalue of $-1$ under particle exchange, coupling $n$ of them produces a composite system that has an eigenvalue of $(-1)^n$.
