coleen, no you don't have to have concrete floors,
in the sense of a slab on grade or a mud bed,
but you do need a substrate that won't move much,
either by flexion or with moisture content. Your ok
as long as your sub-floor meets the minimum standard
standard for rigidity of L/360 deflection or less.
Usually this is achived by at least 5/8" (3/4" preferable)
plywood over 16" oc joists.
