A question about the linear response theory?

I am studying linear response theory and i have a dub :S

if i have <Ψ(0)|O(interaction)|Ψ(0)> ¿can i say that is the same that? <Ψ(0)|O|Ψ(0)>

where Ψ(0) is the wave fuction in t=0 and O is and operator, O(interaction) is the operator in the interaction picture and O is the operator in the schrodinger picture
