“…Insomnia is a major source of daytime impairment (Riedel & Lichstein, 2000; Drake, Vargas, Roth, & Friedman, 2014) and is associated with a number of negative health consequences (Ohayon, 2002). Although a number of factors increase vulnerability to insomnia (see Drake & Roth, 2006 for review), one factor that has gained increasing support is sleep reactivity (Drake, Richardson, Roehrs, Scofield, & Roth, 2004; Drake, Friedman, Wright, & Roth, 2011; Jarrin, Chen, Ivers, & Morin, 2013; Nakajima et al, 2014).
