• four-point boundary value problem
• Leray-Schauder degree
• strict upper and lower solutions
• sign-changing solutions

In this paper we obtain using Leray-Schauder degree theory some multiplicity results for sign-changing solutions of a four-point boundary value problem. We assume the existence of a pair of strict lower and upper solutions and some additional conditions on the nonlinear term f.
