“…Although stepped-care and matching strategies have been identified as important topics for study (Abrams et al, 1996; Fiore et al, 1996), few studies have been published that assess the potential value of these approaches. In terms of stepped-care strategies, the only published research involves studies in which participants initially took 2-mg nicotine gum and were later given the option of taking 4-mg nicotine gum (e.g., Campbell, Prescott, & Tjeder-Burton, 1991; Kornitzer, Kittel, Dramaix, & Bourdoux, 1987; Lando, Kalb, & McGovern, 1988). To our knowledge, only one study has systematically manipulated pharmacotherapy contingent on cessation difficulties.…”
