Criticisms of the scientific validity of the RTS construct are that it is vague in important details; it is unclear what its boundary conditions are; it uses unclear terms that do not have a basis in psychological science; it fails to specify key quantitative relationships; it has not undergone subsequent scientific evaluation since the 1974 Burgess and Holstrom study; there are theoretical allegiance effects; it has not achieved a consensus in the field; it is not falsifiable; it ignores possible mediators; it is not culturally sensitive; and it is not suitable for being used to infer that rape has or has not occurred. PTSD has been described as a superior model since unlike RTS, empirical examination of the PTSD model has been extensive, both conceptually and empirically.
