  We study q-stars in Brans-Dicke gravitational theory. We find that when the
Brans-Dicke constant, $\omega_{\textrm{BD}}$, tends to infinity, the results of
General Relativity are reproduced. For other values of $\omega_{\textrm{BD}}$,
the particle number, mass and radius of the star and the absolute value of the
matter field are a few percent larger than in the case of General Relativity.
We also investigate the general scalar-tensor gravitational theory and find
that the star parameters are a few percent larger than in the case of General
Relativity.
