“…Much research on the prevalence of MSU has been conducted in clinical samples (Blow et al, 2011;Byqvist, 1999;Martin, Kaczynski, Maisto, & Tarter, 1996), university samples (Barrett, Darredeau, & Pihl, 2006;Martin, Clifford, & Clapper, 1992) or youth samples (Collins et al, 1998;Merrill, Kleber, Shwartz, Liu, & Lewis, 1999). Fewer studies have assessed MSU in the general population.…”
