“…Although a specific program of primary prevention is not feasible given the current state of knowledge, enough is known to implement a secondary prevention strategy. For example, there is increasing evidence of the effectiveness of cognitive behavioral therapy (CBT) for addressing such symptoms (Buckelew, 1989;Martin et al, 1989;Peck et al, 1989;Salkovskis, 1989;Blanchard et al, 1990;Hellman et al, 1990;Skinner et al, 1990;DeGuire et al, 1992;Keefe et al, 1992;Sharpe et al, 1992Sharpe et al, , 1996Payne and Blanchard, 1995;Sharpe, 1995;Speckens et al, 1995;Van Dulmen et al, 1996;Deale et al, 1997;Fulcher and White, 1997;Clark et al, 1998). Studies also indicate that medically unexplained symptoms are more difficult to treat once they have become chronic (Kellner, 1986(Kellner, , 1991Kroenke and Mangelsdorff, 1989;Craig et al, 1993;Barsky, 1998), providing an additional incentive to identify and treat sufferers early.…”
